How to install a sink in the kitchen: rules for installing mortise and free-standing models. Installing an undermount sink into a countertop: a step-by-step guide How to glue a sink to a kitchen countertop

How to embed a sink into a countertop

DIY furniture

When replacing a sink or purchasing a new one kitchen set there is a need to embed the sink into the countertop. This work can be entrusted to furniture makers or a craftsman can be called in, but this is not always possible. You can embed the sink into the countertop yourself, and in this case you can be confident in the quality of the work. This process is not very difficult, but at the same time it requires attention and high-quality execution. An incorrect insert will cause water to seep into the tabletop, causing it to become wet, swell and deform. The service life of the tabletop depends on the correct installation of the countertop, regardless of the material.

When purchasing a sink, you need to find out how it is attached. There are fasteners for sinks different designs and shape, but it may also differ in quality. It is important to select fasteners for a specific sink model, and at the same time choose the highest quality products.

The sink embedding process includes several main steps, described below.

Installation of a mortise sink is more complicated than in the case of an overhead model, but this is compensated by the absence of dampness between the cabinets of the kitchen unit, which is possible with an overhead sink. The differences between these two options are that the edges of the mortise models have a height of 5 mm, while the edges of the overhead sinks are stamped and equal to 3 mm.

As for the shape of a built-in sink, there is no difference between installing a round and rectangular sink.

To install a mortise tabletop into a chipboard tabletop you will need following materials and tools:

Pencil

Construction corner

crosshead screwdriver

Jigsaw

Silicone sealant

Self-tapping screws

Choosing a sink installation method

Exist different variants washing installations, which depend on the features kitchen furniture and the wishes of the customer. An undermount sink can be installed below, above or flush with the countertop. Options flush and below the countertop provide sinks without sides, which provide many advantages: ease of cleaning the work surface, big choice bowl for washing and accessories for them, extension working area, Beautiful appearance. In any case, it is necessary to carefully seal the sink seams to prevent water penetration.

Tabletop markings

It is necessary to correctly mark the countertop where the mortise sink will be installed. To do this, you need to take into account the following: at least 5 cm away from the front side, and at least 2.5 cm away from the back side. These figures may vary depending on the design of the kitchen unit, the size of the kitchen or the location of the sink.

Using a pencil, draw two perpendicular lines at the place where the countertop is mounted, at the intersection of which the center of the sink bowl will be located. After this, mark the boundaries of the edges, place the inverted sink on the countertop and outline its outer contours.

Each sink must be equipped with fastening elements. They can be made of plastic or metal, and it is better to give preference to the second option - such fastenings are more reliable. The fasteners from the fastening kit are installed on the sink, and the fasteners for the countertop are set aside for now.

Next, measure the exact width of the side, taking into account the protrusions of the fasteners. For stainless steel sinks this size is 12 mm. On the countertop, inside the already drawn contour of the sink, another contour is drawn, taking into account the size of the side, which will indicate the cutting line. It is necessary to accurately measure and draw this contour so that during subsequent installation the sink fits freely into the groove, and there are no distortions or excess material anywhere.

From the outer contour it is necessary to step back inward by the width of the side, while a backlash of no more than 2 mm is allowed.

Cutting a hole for a sink

If the sink bowl fits freely into mounting hole and the play is small, then everything is done correctly. If the sink does not fit into the hole and gets stuck somewhere, then the protruding parts must be trimmed with a jigsaw.

Sealing the sink

After forming the mounting hole, the walls of the table top at the cut site are cleaned of dust and applied silicone sealant. Then a special seal is glued to the side of the sink along the entire contour.

After this, you need to check the evenness of the seal. If it protrudes somewhere by more than 1 mm, then it is trimmed with a sharp knife.

After attaching the seal, silicone sealant is completely applied to it and proceed directly to installing the sink.

Installation of a mortise sink

The sink is lowered into the mounting hole and its edges are aligned along the first marked contour. Then take the tabletop fasteners and use them to secure the bowl without fully tightening it. It is important to align the sink strictly along the outlined contour. When the product is completely installed according to the marks, you can finally tighten all the fasteners.

If everything is done correctly, then a little sealant should be squeezed out along the entire contour of the sink. Using a clean cloth or napkin, remove excess sealant and pencil markings, and leave the sink for a day to dry completely.

At correct execution work, the mortise sink and kitchen countertop will serve you for a long time and reliably.

How to embed a sink into a countertop with your own hands

Every kitchen must have a sink, as it is an integral attribute and hardly any housewife can do without it. For those who have never installed sinks, it will be interesting to know that currently there are two methods - overhead and mortise. You can familiarize yourself with each of them in this article and then choose the most suitable one for yourself.

The choice of method will depend on several factors - the customer’s desire and the characteristics of the kitchen furniture. You have the opportunity to install mortise sinks as you like or suit the chosen interior - below the countertop, flush, or above. Both options, except the one above, involve the use of separate bowls without any sides. By installing a built-in sink you will receive a number of advantages: a beautiful aesthetic appearance, the work surface is quite convenient to care for, there is a wide choose sinks, of various sizes with all kinds of accessories, the working area is significantly increased, hygienic.

Whatever installation you choose, the seams formed must be carefully sealed. How to install a compact dishwasher. A built-in sink also has a drawback - it is quite inconvenient to connect the communications; to do this you will have to crawl under the sink or turn over the countertop.

If your choice is to install a built-in sink, then this service will cost you a little more, but in return you get a complete absence of dampness between the cabinets, which is for the kitchen. The sinks differ only in the height of the side and the brackets: the side of a stamped sink is 3 cm, and the side of a mortise sink is 5 mm.

Quite often, professional specialists are asked the question of how to properly install a round sink? In reality, there is no difference in the installation of a rectangular and round sink; the technology is similar everywhere.

Let's look at the most popular installation option - installing a sink in a countertop made of such a common material as chipboard. To carry out this “operation” we will need a tape measure, a knife, a Phillips screwdriver, a pencil, a ruler and a construction corner. Don’t forget to get yourself self-tapping screws, a jigsaw, an electric drill and silicone sealant.

So, let's start looking at the installation, first you need to prepare the table and make all the necessary markings, of course there are no specific frameworks, each case is unique. In most cases, the indentation from anterior wall is 50 mm, and from the back 25 mm, but I repeat once again that these data are not a rule for all types of countertops. Sometimes calculations will depend on the kitchen furniture itself and its features.

Now we find the golden mean, for this we draw two perpendicular lines corresponding to 90˚ on the table and the place where they intersect will be the center of our sink, then we outline the outer contour.

Manufacturers can complete their sinks various elements fastenings, mostly either plastic or metal; if you have a choice, then give your preference to all-metal ones. As practice shows, they are more practical to use and can last longer. We install the fasteners that are attached to the sink first, and those that are on the countertop should be put aside for now.

Now the turn has come to the most important thing - this is measuring the width of the side (the protrusions of the fastenings must be taken into account). In case if stainless steel sink has standard dimensions, the deviation will be 12 mm. We now have an outer circle, and next to it draw an inner one.

According to your calculations, the sink should fit freely into the countertop so that everything goes perfectly. Take the outer drawn contour and, retreating a couple of millimeters, begin to manually draw the inner circle.

Let's start cutting in the countertop; we will need one hole if we are talking about a round sink, or up to five if we need to install a trapezoidal or rectangular one. The through hole must be made inside the second contour, but at the same time, so that it does not touch the cut line.

The jigsaw should fit into the countertop with outside, so we will drill the hole from here, and it’s much more convenient. We carefully follow the line with a jigsaw and, as we move, insert self-tapping screws into the resulting hole, this way we will protect ourselves from the sawn-off tabletop falling down. Once the hole is made, lower the sink into the countertop to check that everything is done correctly. IN ideal The sink should fit freely into the hole and have a slight play; if not, then we cut off the “problem” areas with a jigsaw.

Now it’s a small matter - we clean the walls and cut areas from dust and sawdust, after which you can apply sealant to the entire surface. We glue the seal along the entire perimeter of the sink; if in some places it sticks out more than 1 mm, it should be cut off with a knife. As soon as the seal sits well on the sides, we now apply silicone sealant around the entire perimeter of the sink itself.

Finishing touches for installation

Now we have come to the final moment of work on carpentry machine. We put our sink in its future place and align it along the first contour, now we take the clamps that we had previously put aside and install it, but be careful, you need to constantly monitor the fit of the sink so that it does not move anywhere.

After complete installation and properly tightening the fasteners, the remaining sealant should be squeezed out, then we take a damp cloth and carefully remove traces of markings and remaining sealant. The structure should be left for a day for complete hardening and installation.

Is it possible to remove bulges on chipboard around a built-in sink?

Is it possible to remove swelling on the chipboard around a built-in sink?

** Sage (14993) 5 years ago

Theorists.

1.Remove the sink. 2. Select a groove under the swelling. or stupidly pick out the sodden rot. the area is larger than the swelling, place a hardwood board or chipboard on top and compress with a powerful clamp. looked. we saw that the hernia was pressed in (under the board, if it didn’t press all the way, place 5-6 pieces of paper over the area of the swelling. This will create some emphasis on the damaged surface. (cut out the leaves according to the area of the hernia) 3. drive epoxy glue there (take bourgeois or Moment in 2 syringes, carefully read the instructions, especially the polymerization time.) Since the curing time of the glue is insignificant, first practice laying and pressing.

Now after pinching, take a household hair dryer and heat the glued area for 10 minutes.

If there is not enough glue for the entire volume of the gap, then when applying the glue, proceed as follows - apply part of the glue to the walls of the hole, and quickly mix part of the glue with the scooped out sawdust and fill up the missing volume with this mass. from start to finish 30-50 minutes of work.

From the heart so that the thickness of the silicone is as thick as a finger so that there are no gaps left. then we install the sink in place, first coat the cutout with silicone around the perimeter. The pot stood up. pulled it in, removed the excess silicone (and it should protrude around the entire perimeter..) and waited for it to dry completely. Using a thin knife, cut the silicone around the perimeter of the sink and remove the tape.

You can use the sink after you have installed it and removed excess silicone.

At work I simply cut out the defect and add volume with polymers.

I tint epoxy glue (only from the Dzerzhinsky plant) and write out a fragment... Then I restore the surface texture.

How to embed a sink into a countertop - make a mounting hole

Installing a sink into a countertop - the finishing line

1 Installing a sink in a countertop - determining the method

The choice of one or another installation method is determined by the characteristics of the kitchen furniture and the desire of the customer. Undermount sinks can be installed above, flush or below the countertop. The last two are completely separate bowls of various shapes without sides. This installation of mortise sinks creates many advantages:

very hygienic;

easy maintenance of the work surface;

expansion of the working area;

a large assortment of all kinds of sinks and accessories for them;

aesthetic appearance.

For any installation option, it is necessary to seal the seams. The only inconvenience of a built-in sink is the supply of communications, for which it is necessary to penetrate under the sink or turn over the countertop.

Installing a built-in sink is somewhat more expensive to install, but it compensates for this by the absence of dampness between the kitchen cabinets, which is possible if a cabinet with an overhead sink is installed. The fundamental difference between the two types of sinks is the design of the side and brackets; for a mortise sink the side has a height of about 5 mm, while for an overhead sink the stamped side is 3 cm high.

Experts are often asked the question of how to install a round sink. In principle, there is practically no difference between installing a rectangular sink and a round one. Below we will describe how, following the advice, you can install a mortise sink made of stainless steel (the most popular material) with your own hands using ordinary power tools.

Installation of a sink in a countertop made of chipboard (the most common type of kitchen countertop) is carried out using a pencil, tape measure, ruler, construction corner, Phillips screwdriver, knife. As well as power tools: jigsaw, electric drill, self-tapping screws and silicone sealant.

2 Installation of a mortise sink - marking the territory

Installing a sink into a countertop begins with marking the area where it will be installed. Typically, the distance from the front side of the tabletop is at least 50 mm, and from the back - about 25 mm or less. But these figures are not absolute and universal; in each specific case they may be different, depending on the size of the sink, the features of the insert, as well as the kitchen furniture.

On the tabletop, draw two perpendicular (90˚) lines with a pencil, the center of their intersection marks the center of the bowl, and mark the boundaries of the edges. After this, we place the inverted sink on the markings made and carefully outline the outer contour of the product.

In addition to the product itself, the kit must also include fastening elements. Manufacturers complete their products with different types (metal or plastic). If you have a choice, it is better to give preference to all-metal ones; they are more reliable in operation. We install the clamps on the sink, and those that are attached to the countertop need to be set aside a little.

The next step is to accurately measure the width of the side, taking into account all the protrusions of the fasteners. Typically for stainless steel sinks this width is about 12 mm carpentry tools names and photos. On the tabletop, parallel to the drawn outer contour, but inside it, draw another contour (cut line).

It must be drawn in such a way that the sink bowl can fit into it freely. To do this, we step back from the outer contour inward by the width of the side, allow about 2 mm of play on each side, and draw the inner contour by hand.

3 How to embed a sink into a countertop - make a mounting hole

In order to cut a mounting hole, make a hole in the countertop in one (if the sink is round) or 4-5 places (if the sink is rectangular or trapezoidal) through hole so that it is inside the second contour, close to the cutting line, but does not touch it.

You only need to drill a hole with front side countertops. This will be the entry point for the jigsaw blade. After this, we make a closed cut along the cutting line. During the process, it is necessary to periodically screw self-tapping screws into the gap, which will serve as temporary fasteners in order to prevent the sawn-off tabletop from falling down. After this, we lower the sink into the sawn hole and check that the work was done correctly.

If the sink fits in freely and has a slight play, then everything is done correctly, but if not, then trimming with a jigsaw is necessary. After this, we clean the sawn walls of the tabletop from dust and apply silicone sealant.

We glue the seal along the entire contour to the side of the sink. If it protrudes somewhere by more than 1 mm, it must be trimmed with a knife. When the seal is in place, apply silicone sealant to it in a continuous strip. Now we have come close to how to install a sink into a countertop.

4 Installation of a sink into a countertop - the finishing line

Having lowered the sink into the mounting hole, we align it with the first circuit. After this, we take 2-4 previously set aside fasteners and fix the product (but do not tighten it completely), while constantly monitoring its position relative to the contour.

When the product is clearly installed on the markings of the first circuit, we finally tighten all the fasteners. Indirect confirmation of correct installation is the squeezed out sealant. We wipe off the markings and excess sealant with a clean napkin and leave the entire structure for a day for the sealant to harden.

We hope that after reading this article, questions about how to install a built-in sink will disappear, or at least there will be much fewer of them.

Having purchased kitchen furniture and plumbing fixtures, many turn to professionals for help. But it often happens that there is no one to expect help from and you have to do everything yourself.

You need to learn in advance how to install an overhead sink on a cabinet in the kitchen in order to be prepared for possible difficulties and nuances.

So, we purchased convenient plumbing fixtures that fully meet the owners’ needs in practicality and appearance. By the way, today sinks made of of stainless steel. Firstly, they are affordable, light weight, and durable to use.

The universal metallic color can be combined with a variety of color solutions in room.

Installation is quite simple, there are only two stages:

Assembling the sink cabinet;
Installation of an overhead stainless steel sink on a cabinet.

The sink is an indispensable attribute of the kitchen. You can easily install it yourself - you don’t need to have any special knowledge and skills.

Furniture assembly

The first stage requires preparing the furniture itself so that the plumbing can be installed. Usually delivered to the customer in disassembled form. If you don’t know how to assemble a sink cabinet, the instructions included with the furniture will help.

Looks like a diagram.

The standard set is:

2 side walls;
2 doors (or one);
Bottom;
3 frames for rigidity;
Fittings, corners, screws.

You need to have a screwdriver on hand to carry out assembly, or a standard furniture hexagon.

Installing a sink: what is needed for this?

How to attach a stainless steel sink to a cabinet so that it holds well and the installation itself does not take too long? To do this, you need to have accessories and tools, thanks to which installing the sink on the cabinet will not be much of a problem.

Secure the sink with sealant without additional accessories It's possible if it's light. If the overhead sink is heavy, then installing it on the sealant will lead to the collapse of the structure. In this case, it must be fastened with self-tapping screws.

The classic tools and accessories used for such purposes are:

Drill, screwdriver;
Screwdrivers;
Ruler;
Pliers;
Drills (for wood);
Self-tapping screws;
Sealant (we’ll give it Special attention Further);
Masking tape;
L-shaped corner.

The above items are also suitable for installing a sink on a countertop.

But experienced craftsmen only need a sealant and corners.

Installation

We lay out the tools and accessories in advance so that they are at hand. It is also advisable to decide on the mixer and siphon so that everything is installed at once, otherwise it will be difficult to install later.How to attach a stainless steel sink to a cabinet? This is not difficult if you have already completed the assembly of the frame itself.

L-shaped fasteners are installed, either included in the kit or purchased separately.

For fastenings, it is better to purchase L-shaped plates with oblique slots at a fastening store. You will need 4-5 plates.
Attach with inside fasteners and mark under them the places where it is necessary to screw in the self-tapping screw. Drill a hole (not through) 0.5 cm above the mark, screw in a self-tapping screw and install the fastener. Do the same actions in other places of the structure.

During the assembly process, make sure that all holes are at the same level.
Next, assemble the plumbing product, attach the siphon with all the gaskets to it, and attach the mixer.

Before installing the overhead sink itself on the base or cabinet and securing it, you need to assemble it completely - secure the siphon and mixer in their places, install gaskets.
Treat the ends of the walls with sealant. It is needed so as not to protect the furniture from moisture.

This product provides additional fastening of the sink to the cabinet in the kitchen.
Now you can start fixing- place it on a furniture frame, where the fastenings are placed on self-tapping screws.

The fasteners are placed on self-tapping screws and moved along the slot. This presses the sink against the cabinet.
Do it plumbing work for connecting water supply and drainage in the kitchen.

Take care of the accuracy of the work and reliability.
After attaching the stainless steel sink to the cabinet is completed, you can check it for leaks. The sink fills with water. Check if water is seeping out at the junction of the sink and siphon.

If water leaks out, the system is assembled incorrectly.
Installing kitchen cabinet doors- the final stage, which will become the final point in plumbing work.

The sink is secured to the cabinet with fasteners and a sealant. This is the most reliable way, quite durable.

So the question of how to install a stainless steel sink on a cabinet has been resolved. If the work is done correctly, it can stand for a long time.

Many people attach the sink to the countertop. There are options when, when ordering kitchen furniture, the need for a hole in the countertop for installing plumbing is specified. Then there will be little work involved in installing the sink.

If there is no specially allocated space on the countertop, then you will have to do everything yourself.

Mark the contours on the surface with a pencil. Take into account the margins from the edges (5 cm). Take measurements for the bowl.

Remember that the gap from the edge of the countertop to the side of the sink must exceed 50 mm. If this distance is less than 50 cm, then the sink needs to be deepened.
Make a hole in the corners of the outline.

To make a hole in the tabletop you will need an electric jigsaw.
Apply masking tape to the outer side of the outline so that the surface around it is not damaged when working. Before cutting the opening, secure the part to be removed from below so that if it falls, it does not damage the surface underneath.

To avoid chipping on the front surface, choose the opposite direction of the tooth.
Treat the ends of the countertop with sealant, assemble all the plumbing elements (mixer and siphon) and install. This will prevent moisture from getting under the structure, thereby spoiling the appearance of the furniture by deformation and delamination.

Stepping back a couple of millimeters from the edge of the hole, we apply the silicone in a thickness just above the side of the sink.
Secure with clamps (included with purchase).

The sink needs to be inserted into the hole and the edges should be pressed firmly so that the silicone strands take the shape of the sink and left for a few minutes.

So, having looked at how to attach a stainless steel sink to a cabinet with fasteners and to a countertop, you will notice that doing this is not as difficult as it seems.

The most difficult thing is to make the hole correctly. If it turns out to be larger than expected, the paws will not be able to hold the sink.

Selecting a sealant

Big role in installation work plays a sealing role. The following types of products are available on the market:

Silicone acrylic;
Elastic silicone;
Polyurethane silicone.

When purchasing, you need to pay attention to the features and characteristics of the sealant: shrinkage, adhesion, purpose.

Apply the product to a dry, clean surface to ensure maximum adhesion. If the surfaces are not fully prepared for sealing, then moisture may penetrate into the cracks, which can lead to the growth of fungus and mold.

Typically, elastic silicone sealing material is used. It is easy to use and quite reliable.

Summing up

Advantages of installing a sink yourself:

There are tools in almost every home; attaching an overhead sink to a cabinet can be done using almost improvised means;
You can save on the cost of a professional plumber by doing the steps yourself;
If the plumbing product did not come with any fasteners, then purchasing them is not a problem.

If you cannot install the plumbing yourself, it would be better to turn to professionals.

VIDEO: Installing a stainless steel kitchen sink.

All modern sinks are divided into built-in and overhead sinks based on the type of placement on the washing base. In this case, the surface of the sink itself can be below the level of the desktop, above the plane of the countertop, or be flush with it. But be that as it may, the bowl under the mixer should be mounted between those parts of the kitchen set that are intended for serving dishes, cooking and placing dirty dishes. The cabinet to which the sink is attached is usually separate element kitchen interior. Integrated and built-in sinks are installed in a continuous work surface floor modules. In this article we will talk about how the sink should be attached to the countertop from the bottom, top or flush, and how to carry out the installation correctly similar designs.

Fastenings for modern sinks

The attachment for the sink to the countertop in the case of a built-in model should be as reliable as possible so that the sink bowl is well fixed during installation. This type of mounting hardware greatly simplifies the installation and subsequent disassembly of the sink. We will consider it further.

Features of fasteners and main purpose

Overhead and mortise sinks have almost replaced other models of kitchen sinks due to their practicality, beauty and ease of use. This type of sanitary ware is ideal for installation in non-standard modern countertops, which require maximum integration into the overall interior ensemble of all household appliances. Its main feature is that there should be no traces of fasteners, cracks or gaps in the visible areas and on the surface. So, in order to implement this requirement, you will need reliable hidden fasteners that can simultaneously and unnoticeably hold the sink bowl in the countertop.

Fastening device:

The fastener consists of two main elements and a clamping screw.
The lower part is attached to special holes or grooves in the sink apron.
The upper part is cut into the tabletop with special teeth.
All elements are connected to each other using a screw.
All parts have a hinge connection; the upper part can be bent relative to the lower one at your discretion. It is thanks to this feature that you can first bend the teeth inward, then insert the shell into the hole, and only after that bend them again and firmly rest them on the board.

Important! Fasteners may consist entirely of metal parts or have plastic inclusions. All-metal clamps are considered the most reliable.

Even if you use an all-metal case, it is recommended to tighten all screws only by hand, because the threads on the washer are too fragile and can be easily torn off with a screwdriver.

Is it possible to install without a clamp?

It happens that fasteners for a kitchen sink are lost during transportation or are simply not the right size for a particular countertop because it is too thick. In such situations, it is difficult to find a way out, but it is still possible.

There are several options to solve this problem:

Attach the sink using sealant or glue.
Make your own fastening from parts for installing gypsum boards.

Glue mount

Considering the fact that the sinks are placed on top of the hole and rest on the countertop, we can say with confidence that the entire load falls on the bowl, and under the resulting forces it is pressed even harder. But sometimes a gap appears between the board and the sides. So, if you install the sink on the glue and press it with some weight while it hardens, the gap will be minimal, and the fixation, in turn, will be reliable.

Important! The biggest problem with glue is the inability to easily and quickly dismantle the sink in case of repair or replacement of the faucet.

Fastening for gypsum boards

You can use a remote mount and cut it into several parts. The antennae are simply inserted into the mount on the sink, self-tapping screws are inserted through one of the holes at an angle and pulled to the countertop. Due to this, an attractive force is created, the fastening is durable and reliable.

Important! Screws can only be screwed into tabletops made of wood. Polymer, composite and stone products are completely unsuitable for this method; only the use of dowels is appropriate here.

Installation of an overhead sink

Overhead types of sinks can be called the simplest in terms of installation. This - traditional version installation of equipment intended for washing dishes. In the interior, such products are free-standing bedside tables, complemented by a panel for folding already clean kitchen utensils.

Installation proceeds as follows:

Before attaching the sink, a mixer, siphon and water supply hoses are installed. The overhead structure is fixed with fasteners with an oblique slot. Then self-tapping screws are screwed into the mounting points, previously marked on the inner surface of the cabinet. This should be done using a screwdriver, and the screws should protrude 5 mm from the walls of the underframe.
The fastening grooves are mounted on self-tapping screws; the sink must be moved until it is firmly fixed. Using fastening brackets, the panel is fixed on the cabinet or pushed into grooves on the base using special slides. Often the kit comes with a tubular adhesive seal that is inserted into a groove on the panel.

Important! The hole between the sink and the cabinet is coated with sealant to prevent moisture penetration.

Supporting bars are installed under the sink to increase the strength of the structure. The underframe itself remains open for cleaning the siphon, sewerage and repairing pipeline connections.
On last stage it is necessary to tighten all the screws, remove the sealant protruding at the joints.

Installation of an undermount sink

The sink itself can be made of porcelain, stainless steel or earthenware. Installing an undermount sink begins with cutting holes in the countertop.

To install such a container, prepare the following materials and tools:

Electric jigsaw with fine-toothed saw.
Screwdriver, drill.
Ruler, pencil, tape measure.
Silicone sealant, self-tapping screws.
Spanners.
Construction knife, sandpaper.

Installation diagram of the mortise structure:

Mark the contours of the mounted panel with a pencil; to do this, turn it over and lay it on the countertop. The margins from the edges must be at least 5 cm.
Measure the location of the bowl relative to each edge of the panel. You should have an outline of the hole that you will cut for the sink.

Important! It is necessary to transfer the contours of the sink to the surface of the countertop as accurately as possible. The line along which you will make the cut should move outward from the sides by 1 cm.

Drill a hole at one of the points on the outline to insert the jigsaw blade into. If the bowl has rectangular shape, then holes are drilled in the corners of the resulting contour.
Apply masking tape to the outside to protect the surface from damage when sawing. When cutting out the required opening, screw in the screws to a shallow depth so that the inside does not fall out during operation.
Cover the ends of the tabletop with sealant strictly along the cut to protect the material from moisture penetration. It must be applied along the edges of the panel along the drawn contour.
Insert a sink with a built-in siphon and mixer into the finished opening, and attach it to the countertop with clamps.
Connect the faucet to the water supply, draining to the sewer through a siphon.

Installation of an integrated sink

Now we will look at how to attach a sink to the countertop flush with it to make its use comfortable, maximize aesthetic perception the entire structure.

Important! Installation of mortise sinks is not required high-quality processing cuts, because they are not visible under the panel. In the case of integrated bowls, it is recommended to do this carefully to get an impeccable result. Only compliance with this condition will ensure maximum tightness of all connections and an unsurpassed decorative appearance.

Fasteners for a mortise sink are required part for fixing the sink bowl to the countertop when installing it. This type fastening fittings greatly simplifies the process of installation and subsequent dismantling kitchen sinks, and we want to look at it in more detail.

Sink mounts

Purpose and features

Mortise and overhead sinks have practically forced all others out of the market due to their beauty, practicality and ease of use. It is this type of plumbing fixtures that is best suited for installation in a modern countertop, which involves maximum integration of all fixtures into the overall interior ensemble of the room.

One of the features of such an installation is that there should not even be traces of fastening fittings, gaps, cracks and other technological details on the surface and in visible areas. To realize this requirement, you need a hidden and reliable fastener that can not only imperceptibly, but also with sufficient force, pull the sink bowl to the surface of the countertop.

Of course, plumbing manufacturers took care of such a device, because the “do it yourself” and “finish with a file” options have long been out of date, and modern products should be equipped to the maximum.

Let's consider the design of the fastening element:

The product consists of two parts and a clamping screw;
The lower part is attached to the sink apron in special grooves or holes;
The upper part rests against the tabletop, cutting into it with special teeth;
The parts are connected to each other using a screw, by tightening which we can adjust the distance between them. If the lower part is fixed on the sink, and the upper part rests on the tabletop, then by reducing the distance we will press the sink against the table;
The parts have a hinge joint, and the upper part can bend relative to the lower one. During installation work, this feature allows you to first bend the teeth inward, insert the sink into the hole in the countertop, and then bend them again and rest them against the board.

The product may consist entirely of metal (tin, stainless steel, galvanized) or have plastic inclusions. All-metal clamps are considered more reliable.

Important!
Even in the case of an all-metal clamp body, the screw should only be tightened by hand, since the threads on the washer are weak and can easily be torn off with a screwdriver.

Installation without clamp

There are situations when fasteners are lost or do not match the thickness of the tabletop. In this case, you can do without them, although this is extremely undesirable.

There may be options here:

Use glue or sealant for fastening;
Make the fastening yourself from parts for installing gypsum boards.

Since the sinks are placed over the hole and rest on the countertop from above, all operational loads and forces that arise tend to press the bowl even more tightly. The only issue is the gap between the sides and the board.

If we put the sink on glue (silicone sealant, epoxy resin etc.) and press the bowl with a weight while it hardens, then as a result the gap will be minimal and the fixation will be reliable.

Important!
The main problem with glue is the impossibility of quickly and easily dismantling the sink if necessary for other structural parts.

You can take the remote fasteners for gypsum plasterboard profiles and cut it into two parts. We insert the antennae into the mount on the sink, and insert a self-tapping screw through one of the holes and tighten it to the countertop at an angle. This creates an attractive force, and the fastening is reliable and durable.

Important!
A screw can only be screwed into a wooden tabletop.
Composite, polymer and stone products are not suitable for this method; here it is possible to mount them with a dowel.

The price of fasteners is very low, so there is no point in reinventing the wheel in this case. It is much easier to buy suitable fasteners and save time and effort.

Installation

It is very easy to install the fastener on the sink body and use it to secure the bowl with your own hands.

The instructions will be short and clear:

On the body of the sink we find special grooves or ears for attaching clamps;

One of the indispensable attributes of any kitchen is the sink. It is required to the same extent as a stove (gas or electric). But installing a sink in the kitchen with your own hands is much easier than connecting a stove, if you know basic instructions and the characteristic secrets of such work.

Different sinks are needed, different sinks are important

Indeed, kitchen sinks are produced in a wide range of products, which can make your eyes wide open in a specialized plumbing store. Kitchen sinks can be divided into at least six categories:

Wall-mounted, mortise and overhead sinks. Mounted option is now rare, it is more relevant for communal apartments and government institutions than for modern renovation. But inset and overmount sinks compete with each other in popularity; their long-term reliability and aesthetic appeal are comparable;
Sinks made of stainless steel alloys, chrome-plated or nickel-plated, sinks made of natural granite or porcelain stoneware artificial stone, acrylic and even glass (!). However, due to practicality, 90% of all models are made of stainless steel and representative porcelain stoneware;
Sinks are angular and standard, round, oval, square, rectangular and shaped. The more intricate the shape of the sink, the more difficult it is to give it impeccable cleanliness and maintain a sparkling shine on a daily basis. After all, the sink is used not for beauty in the living room, but for mundane household needs in the kitchen;
By design, a distinction is made between ordinary single sinks and sinks with two bowls (one or different sizes, the same or various shapes etc.). Available comfortable models with water pouring from one bowl to another;
According to the location of the mixer - on the wall or on the sink itself (the first option is rare);
According to the availability of additional options - the possibility of installing a water filter, outlets for connecting washing machine, automatic valves for adjusting drainage, additional taps for connecting garden hoses, etc.

Stainless steel sinks have gained overwhelming popularity due to their reasonable price, durable functionality, and compatibility with the most various repairs kitchen space and ease of sanitization.

You can check the quality of the steel alloy of the sink right in the store - an ordinary flat magnet will stick to it very firmly, but with bad steel the magnet will “fly off” at the slightest vibration.

Granite and steel sinks are available in overhead and inset versions; installing a sink in the kitchen with your own hands is possible for both. However, first we need to take care of the furniture base of our installation efforts.

How to assemble a kitchen sink - install a cabinet

Recessed and overhead sinks are installed in cabinets and cabinets, with opening (less often sliding) doors in the front and an empty opening in the back. The assembly of these elements of the kitchen set has its own characteristics. The fact is that they do not have internal bulkheads; they can interfere with the connection of the sewerage system and water pipes. This means that there will be no additional stiffeners inside the cabinet. If a countertop sink is installed, even the countertop is missing; it is replaced by a steel sink panel.

The assembly of the sink cabinet should be much more reliable and durable than other parts of the kitchen set. It needs to be installed on special supports, because... Even with the best sealing, water leaks are possible. It wouldn’t hurt to treat the material itself with water-repellent compounds. Inside the bedside table, it is necessary to provide fastenings for tightening jumpers - they are installed after connecting the sink to the communications for the strength of the entire structure. The lintels themselves can be made from flat and thick planks, which will serve as additional mini-shelves inside the cabinet.

How to install an overhead sink on a cabinet - brief instructions

Overhead installation option kitchen sink It can be ordinary or “sliding”. In the latter case, the sink itself is equipped with curved slides on the side and front sides, and special grooves are provided on the bedside table. After you have successfully assembled a sink in the kitchen, all that remains is to slide the sink into these grooves, move the structure to the wall - and you can connect the communications.

If you use a direct overhead mounting option, you will have to seal all joints. Qualitative waterproof sealant combines the properties of glue and protective waterproof composition. The upper perimeter of the open cabinet is generously coated with this composition; all that remains is to precisely place the sink itself on top.

A large and heavy overhead sink cannot be installed using sealing adhesive alone!

Otherwise, one day it will fall inside the cabinet along with the dishes, destroying the sewer and breaking off the pressure water hoses. Negative impressions from such an accident will be available to both you and your neighbors below. As well as eliminating the plumbing collapse and renovating two rooms from the personal budget. How to install an overhead sink on a cabinet without the risk of such an incident? Using auxiliary bars or internal sheathing.

Simple overhead sinks are usually equipped with additional fasteners. Massive bars, precisely screwed to the wrong side of the cabinet, are suitable as such. It is necessary to accurately mark the bottom edge of the pre-installed (without glue!) sink and build an internal sheathing along this line. Then the sink will rest on auxiliary bars, and not on the thin end of the bedside table. The operation is similar to hidden installation of sheathing, only in final stage complemented by adhesive sealing of the joint between metal and wood.

Installing a sink in the kitchen - do-it-yourself mortise installation

Before attaching a metal sink to the cabinet using the mortise method, you need to make sure that the cabinet is strong and that the entire structure can be accurately installed in the installation opening. Experiment with moving the cabinet in advance - after fixing the sink you will only have to do this once. After connecting the sewerage and water supply, the cabinet with the sink should stand like a glove, without distortions or vibrations.

How to install a sink in the kitchen with your own hands - step-by-step diagram

Step 1: Marking

Most mortise sinks are sold with a ready-made template; it acts as a packaging container. It is enough to cut out such a template from cardboard and attach it to the countertop at the location of the sink - and the outline seat ready.

If there is no template, you will have to make it yourself. To do this, it is better to use thick cardboard (for example, from a TV or monitor). After measuring the inside of the sink, transfer this measurement to the cardboard surface and cut off a few centimeters more. It is better to cut a piece of cardboard several times than to look for a new piece.

Step 2: Location

The proverb about the need to measure seven times before the first cut is very relevant for our work. Move ready-made template you can move across the tabletop easily and freely - as long as you don’t start sawing right through it. So consider how the tap will open, where the filter will be, how kitchen utensils will be positioned, etc.

The cardboard template should be traced as evenly and accurately as possible. To do this, attach it to the tabletop with ordinary tape and carry out one thin line pencil. After which the “cardboard helper” peels off and goes into waste paper; we will no longer need it. The perimeter of the future hole with outside paste over masking tape by 8-12 cm in order to prevent damage from mechanical tools.

Step 3: Drill and saw

Yes, yes, first mechanical tool It will be a drill, not a saw. A drill with a diameter of 2 mm is selected and several closely spaced holes are drilled in the place where it is convenient to start cutting out the contour. The holes are connected into a single groove using a chisel.

It is convenient to saw the tabletop wood jigsaw. Just don’t forget to stock up on extra blades - thick tabletops are difficult to saw, and the blade is likely to break if it deviates slightly from the vertical. Take your time and move the jigsaw confidently - it is more difficult to correct a crooked cut than to immediately cut a hole along a plumb line, with a strictly perpendicular cut.

Step 4: Complete the installation

Apply sealant to the end of the fresh mounting hole and insert the sink tightly. We hold the sink under load for 10 to 60 seconds (depending on the type of sealing compound). Carefully remove excess glue from the outside and inside of the sink and wait several hours until the sealant has completely hardened. We connect hoses, pipes, sewerage, install a faucet and use the new sink for your pleasure.
