Step-by-step installation of a kitchen sink and useful tips for installation. Installing an Undermount Sink in a Countertop: Step-by-Step Guide Attaching a Square Sink to a Countertop

A set of kitchen furniture includes many components for different purposes. The central element of the set in this room can be called the tabletop. This is not just the main work surface, but also a kind of frame with which kitchen communications, shelves, cabinets and, of course, the sink interact. And if the communication connections are carried out according to standard diagrams with specified hole parameters, then the integration of functional elements into the platform niche itself requires more serious preparation. Cutting and fastening operations are only part of the work steps that a tabletop cannot do without. Implementing these and other tasks on your own is not easy, but it is possible if you follow the instructions.

Preparation for installation activities

Before starting work activities, you should prepare consumables, tools and the washing itself. By this point, the countertop should be installed, and the material of its manufacture should match the sink. The fact is that different countertops, depending on the size and material of manufacture, have different load-bearing capacity. Thin models based on composites can only withstand stainless sinks. If you plan to install a stone sink into the countertop, then you should focus on a high load. In this case, either the tabletop must be made of at least artificial stone, or additional holders must be provided in the cabinet itself under the platform.

As for tools, you should prepare a set of measuring instruments, an electric drill or jigsaw, screwdrivers, an adjustable wrench, a construction knife and a sealant gun. What consumables will be needed depends on the installation method, which will be discussed below. The universal list includes screws and sealant. In addition, do not forget about the plumbing, the organization of which involves the use of a siphon, a water supply hose and a mixer.

Rules for marking

This is a critical stage, during which the configuration of the sink placement will be determined in accordance with its size. Of course, you should start from the parameters of a specific sink, but there are also standard placement rules that the chosen installation scheme should not contradict. First of all, the cutting edge, that is, the line of contact between the sink and the countertop, should be located at least 50 mm from the edge. This value should be maintained regardless of the method used to further install the sink into the countertop.

You can install the sink yourself using both glue and hardware, but in both cases the load on the edge must be minimized. The only exception is the area with the rear end, where the distance from the edge to the cut can be 25 mm, since in this part the pressure on the structure will be less. Also, when marking, you should remember about the communications that will be connected to the central point of the sink - they must fit freely to ensure both water supply and drainage to the sewer.

Cutting countertops to size of sink

After marking, the lines for future cutting should be ready. To perform cutting, two tools are used - a jigsaw and an electric drill. First, a drill comes into play, which will create niches for sawing. If installation is planned, it is necessary to make holes with a depth of at least 10 mm in each corner. Next, from each hole you need to use a jigsaw to connect to another nearby point along a straight cutting line.

A different approach should be used if a round sink is installed in a countertop. It is more difficult to cope with this task on your own, since you will need to perform not a straight, but a curved cut. But you should also start by creating a hole with an electric drill. It will be one. To make cutting easier, it is advisable to initially have a jigsaw designed for figure cutting. Then you should carefully guide the saw strictly along the intended circular line. It is important to avoid even small deviations and to cut smoothly and without jerking.

Installing a sink using glue

The adhesive method of fixing the sink is not the most reliable, but it is practical and, provided it fits tightly, can be quite durable. Before applying the glue, it is necessary to treat the edges of the tabletop at the cut points. For this, fine abrasive materials or a fine-grained grinding wheel are used. Next, a polyethylene-based sealant is applied. It is usually supplied complete with the product.

It is also worth noting that the adhesive method is used to install a stainless steel sink into a countertop, but not stone models, the shift of which can lead to a breakdown in fixation. Both the future contact points of the sink itself and the polished edges of the countertop are first coated with glue. It will be possible to use the sink for its intended purpose only after the composition has completely crystallized - you need to wait about 24 hours.

Installation of sink with fastening materials

Mechanical fixation will provide greater reliability, but there is one caveat. The adhesive composition increases the tightness of the areas where the sink and countertop meet. In the case of screws, the risk of flooding at the joints will be prevented by using waterproof sealants in a larger volume than in the case of adhesive installation. Usually the fastening material is supplied included, so you don’t have to look for special hardware.

A “cross” installation of the sink into the countertop is considered optimal. You can do this installation yourself either using a screwdriver or using a screwdriver manually. The fastening strips are positioned diagonally, after which the complete screws are integrated into the technical holes.

Inset and overhead sinks - differences in installation

Built-in sinks require customized installation, including with a shaped cut countertop. Overlay models are also rarely done without pre-processing the platform, but in this case, markings for future cutting are made along straight lines. As a rule, a square or rectangular shape is prepared, and cutouts of this format are made in special panels in the factory.

What are the benefits of installing a built-in sink into a countertop? It is more difficult to implement figured cutting for such a sink yourself, but in the end it will provide a higher degree of reliability, not to mention aesthetic appeal.

Nuances of installing ceramic sinks

Both ceramic and stone sinks are made using the cut-in technique only. Such models require the creation of a more durable supporting structure with high-quality fixation. It is recommended to fasten using a combined method - that is, using glue and mechanical fasteners. This will ensure optimal installation of the ceramic sink into the countertop.

You can also prepare the internal holding base yourself. This is done using wooden planks that secure the niche of the heavy tabletop under the cabinet. Such planks can also be fastened with nails, but a more preferable option involves the use of self-tapping screws or self-tapping screws.

Connecting the sink to communications

First, the cold and hot water supply hoses are connected. On one side - to the mixer, on the other - to the water supply channel. The integration point of the mixer must contain a rubber seal. Next, a siphon outlet is introduced into the sink - it is advisable to use a curved model, since bottle ones quickly become clogged. A sewer pipe is connected to the siphon.

If it was installed in a countertop, then the communication line should be used as strictly as possible. For example, the nozzle may have a reinforced corner design. At the final stage, it is necessary to check all connections and, if necessary, provide sealing collars at the joints.

During the installation process, regardless of the installation method, a sealant will be used. You should not feel sorry for him, since the joints must be well sealed. However, excess that extends beyond the gaps must be removed before it dries.

Another nuance concerns working with stone and ceramic structures. This is the most labor-intensive installation of a sink into a countertop. It is physically difficult to carry out such installation on your own in the kitchen, so it is better to work with a partner. And one more point concerns the choice of the method of tightening the screws. If possible, it is better to perform such operations without power tools and manually, since excessive force can lead to deformation of the materials of the countertop and the sink itself.

Conclusion

How ergonomic a sink integrated into the countertop will be depends on many factors. The location of the object in the overall configuration of the headset will be of greatest importance. The durability and reliability of the structure will be determined by the installation of the sink in the countertop. Self-installation can guarantee the success of future operation only if the above recommendations are followed, as well as with the high quality of the consumables used.

Particular attention in this context should be paid to the sealant and adhesive composition. It is advisable to choose both products from the lines of major manufacturers recommended for use in the kitchen under harsh operating conditions.

1 Ergonomics in the kitchen

Food preparation must occur accurately and quickly. This is primarily influenced by the location of kitchen furniture and appliances. In accordance with the principles of ergonomics, kitchen equipment must be placed depending on the order of work, that is, from left to right: refrigerator, dishwasher, sink, stove, and between them work surfaces with cabinets.

The minimum distance between individual devices should be:

  • 40 cm between the refrigerator and the sink, as well as between the sink and the stove,
  • 40 cm between the refrigerator and the stove.

For right-handed people, the most convenient way is to place separate workspaces from right to left. Regarding the sink, this means that the sink should be on the right and the drain on the left.

It is best if the sink is installed near the connection to the water supply and sewerage system.

The drainage system at the sink is made of pipes and siphons with a diameter of 40 and 50 mm.

2 Types of sinks

When choosing a kitchen sink, you should pay attention to the following factors:

  • Capacity. It is determined by the number and size of dishes washed daily.
  • Functionality. It is determined by the nature of the work carried out in the kitchen, the number of additional bowls in the sink and wings for drying. If you have to carry out several personal manipulations in the sink at the same time, then these compartments will be very useful.
  • Ease of use. You must be comfortable standing and working at the sink.
  • Stability and durability. These parameters are determined by the material from which the sink is made.
  • Combination with kitchen interior. The sink should match the style, design, color scheme and, of course, the size of the entire kitchen.

From an installation point of view, there are two main types of sinks:

  • applied to a kitchen cabinet (overhead),
  • built into the kitchen countertop (mortise).

When installing built-in sinks, it is necessary to accurately cut a hole in the countertop for the selected sink. In the case of slabs made of chips, this is not a big problem, but if the tabletop is made of stone, conglomerate or composite, then special cutting tools are necessary. 

MATERIALS USED FOR THE PRODUCTION OF WASHES

Surface-mounted sinks are made of stainless or enameled steel. The two most common options for the appearance of steel sinks are smooth and linen-textured.

Drop-in sinks are made of stainless steel, mineral-epoxy composites and hard artificial materials.

Composite sinks often have an impressive grain structure, reminiscent of polished stone. Sinks made of artificial materials can be completely one-color. This group of kitchen accessories is characterized by an impressive appearance and high resistance to abrasion, scratches, dents and high temperatures.

WASH FORMS

Steel sinks have the widest range of shapes and varieties. In addition to the usual single-bowl sinks, there are sinks with several bowls (usually 2-4), which can be either shallow or deep, with additional side dryers.

3 Installation of an overhead sink

  1. The overhead sink is designed for installation on standard cabinets of standard widths 50, 60, 80 cm. For installation you will need: a tape measure, a screwdriver, 4 wood screws, clamps for the overhead sink 4 pcs, sanitary silicone.
  2. Installation is carried out after installing the cabinet in the chosen place in the kitchen.
  3. We determine how far the sink should hang over the front wall of the cabinet. We subtract the second size from the first and get the distance where the screws should be screwed in.
  4. We screw the screws into the upper part of the cabinet walls - do not screw them all the way, the heads should stick out a little so that they can snap into the holes in the base of the sink.
  5. We insert the sink - the heads of the screws should fit into the round fragments of the holes.
  6. Push the sink towards the wall so that the screws are locked at the end of the base.
  7. Check to see if the sink is inserted tightly; if it moves, remove it and tighten the screws.
  8. We insert it into the cabinet again.
  9. This installation method ensures a stable installation of the sink. If there is a metal splashback on the back of the sink, it should fit snugly against the wall.

4 Installation of a mortise sink

Built-in sinks are designed for installation in kitchen countertops.

The first step is to cut a corresponding hole in the tabletop. In tabletops made of wood and laminated particle boards, we cut out a hole with a wood jigsaw.

For countertops made of stone, conglomerates or composites, special devices are used when cutting holes, so this service must be ordered when purchasing them. It is necessary to indicate the dimensions of the hole and the exact location of installation of the sink. The size of the hole for the sink is obtained by measuring the length and width of the apron on the bottom of the sink.

ATTENTION

The hole should be 0.5 cm wider and longer than the apron.

1. The apron serves for stable installation of the sink. Some sinks come with a sample hole for the sink, which you just need to outline on the countertop.

2. Use a jigsaw to cut a hole in the tabletop.

3. We insert the seal under the sink, which is included with the sink.

ATTENTION

Wooden and laminated countertops must be protected from moisture after cutting the hole. Cover the edges of the cut hole generously with sanitary silicone. After it dries, you can begin installing the sink.

Steel sinks are fixed in the hole using clamps. The upper part of the mount is attached to holes drilled in the sink apron. The lower part rests against the bottom of the tabletop. Both parts are connected with a screw. By tightening the screw, we clamp the fastener and fix the sink in the hole.

4. After centering the sink in the hole, screw the first fastener. We don’t twist it all the way, leaving it a little loose.

5. In the same way, fasten the fastening located opposite.

6. Carefully tighten all the fasteners one by one.

7. The last stage of installation is to tighten all the screws one by one so that the entire contour of the sink rests on the countertop.

8. We install the mounting points of the latches in the hole cut out in the countertop in accordance with the drawing attached to the product by the sink manufacturer.

9. Screw the clamps into the designated places. There can be from 6 to 12 pieces. 

10. We glue self-adhesive sealing tape along the edges of the sink, which, depending on the manufacturer, is included in the kit or sold separately.

11. Fix the sink by carefully inserting it into the hole in the countertop. First, the tabletop will rest against the edge of the apron on the latch tongues.

12. We apply pressure to the sink at the places where the latches are installed. The tabs will snap into the recesses made on the sink apron. After fixing is completed, you can begin installing the mixer and siphon for draining.

ATTENTION

The precise placement of the latches and the precisely cut hole ensure that the sink is properly secured.

The times when the choice of plumbing equipment was minimal are long gone. Modern appliances are very diverse, so even the most experienced home craftsman sometimes does not know how to install a sink in a kitchen countertop. Let's look at the design features and step by step analyze the simplest method.

How to choose a sink for a countertop

In any plumbing store, the buyer will see a large number of the most important ones, but not all of them are suitable for insertion. There are several options:

  • Invoices. They are installed on the cabinet from above and completely cover it. Extremely easy to install. The main disadvantage is the presence of gaps between the furniture and the sink.
  • Mortise. They are inserted into the hole provided in the base. Installation is a little more complicated, but the cuts are reliably protected from moisture.
  • Integrated. Practical combination of sink and work surface. The side can be at different levels: level with the table, below it, etc.
  • Under-table. Integrated only in: hardwood or stone. The edge of the bowl drops below the level of the base.

In practice, mortise devices are most often installed. They are durable and attractive, easy to use. The most popular equipment is made of stainless steel and artificial cast.

Rules for installing a countertop kitchen sink

Before starting installation work, it is worth deciding on the place where the structure will be built. It is usually tied to . However, modern technologies make it possible to embed the device anywhere in the headset. When choosing an installation location, it is advisable to follow these recommendations:

  • The bowl is placed as close to the work area as possible, making it more convenient to cook.
  • The design divides the work surface into two parts: dirty and clean. In the first, food is processed, in the second, they are served.
  • The sink should not be placed near the stove or refrigerator. It's not practical.
  • It is advisable that there be light where the bowl will stand. If necessary, additional lighting is provided.

It is best to choose a deep appliance: you can wash large dishes and other large items in it. The mixer should be low - This combination will give a minimum of splashes during operation.

What to prepare before installation

For high-quality insertion of equipment into the countertop, in addition to the plumbing fixtures, you need to prepare:

  • electric drill and jigsaw;
  • Screwdriver Set;
  • drill bits;
  • pliers;
  • square, pencil and ruler;
  • fasteners, if they are not included with the device;
  • rubber seal;

The sink should be carefully inspected before purchasing. It should not have any dents or scratches if it is made of stainless steel. If not, you need to additionally check for chips. Even small defects in the sink will not allow it to fit tightly to the base, and this is unacceptable. It is optimal that the kit includes good quality fasteners. Otherwise, it is better to purchase them.

Inserting a sink into a countertop: 5 main steps

The equipment installation work is carried out in five steps.

1. Perform marking

Place the table top face up. Unpack the plumbing fixture. It is optimal if the kit includes a template for marking. If not, we will outline the product itself. To do this, turn it over and place it in the place where it will be placed. It is very important that the built-in sink does not prevent the cabinet doors from opening freely. This needs to be checked.

If everything is fine, draw a contour with a simple pencil and get a line on which the edge of the kitchen sink will be located. Now you need to define the inner contour of the bowl. To do this, we measure its side; its length is on average 12 mm. We put the resulting value inward from the intended line and mark the internal border. This is where you will need to cut the hole. To prevent chipping when cutting, apply masking tape along the contour.

2. Working with the hole

We take a drill and put a drill with a diameter of about 10 mm into it. We drill a hole on the previously outlined internal contour. We install a jigsaw file into this hole and carefully cut out an opening for the bowl. If the device has a quadrangular shape, drill holes are made in each of the corners.

The important point is to hold the sawn part. At the moment when the cutout is almost ready, it may fall out and break the laminated coating. Therefore, you need to either hold it from below or secure it with something suitable. These can be clamps, self-tapping screws, etc. Carefully remove the cut piece and clean the hole from fine dust.

3. Process the cut

You need to understand that absolute sealing of the cutting line is impossible. But it’s worth trying to ensure that it is protected as much as possible. Otherwise, this problem area will first become dark, which will indicate the appearance of moisture inside the wood board. Then pockets of mold may form, and the foundation will become unusable.

We start with sanding. We clean the cut with fine sandpaper, getting rid of all irregularities, and removing dust. Then we take the sealant and apply it to the cleaned surface. Considering that the area will not be noticeable, you can take the usual white composition. For ease of application, we use a small spatula; if you don’t have one, you can apply the product with your finger. Carefully smooth the sealant so that it covers the entire cut with a thick, smooth layer.

4. Preparing the sink

Before installing the equipment, it is necessary to apply sealing tape to it. We turn the bowl over and determine the place where the seal will be located. We take the rubber band that should be included in the delivery kit, and use a rag soaked in gasoline or solvent to degrease it.

Apply a continuous layer to the sealant. There should not be too much of it so that it does not come out during the gluing process. Apply the tape to the edge of the sink and press until the composition sets. It may be that the kit comes with a self-adhesive seal. It's easier to work with. You need to remove the protective strip and stick on the insulator.

5. Attaching the sink to the countertop

Apply a layer of sealant between the side and the seal. Since there is a small chance that a strip of the composition will be visible, you can choose a mixture that matches the color. For example, black or any other. Transparent sealant is a universal solution.

Then we place the fastenings on the back side of the bowl so that they are not fully secured. Now we insert the sink into the base. We begin the installation from the area where the mixer will be mounted.

We tilt the bowl and carefully lower it into the hole, putting the fragment in place. Next, we gradually install the structure so that the sides fit on the inside of the base. To ensure that the bowl fits tightly, carefully press it, moving around the perimeter of the equipment. In this case, excess sealant may protrude from under the device. We immediately remove them with a rag. After hardening, it will not be possible to do this unnoticed. We carry out the installation by tightening the fasteners.

At this point, the installation of the sink can be considered complete. All that remains is to connect it to the sewerage system, put it in place and connect it to the water supply pipeline. It cannot be said that installing mortise equipment is very simple. However, if you wish, you can do it yourself. Accuracy, patience and strict adherence to instructions guarantee a good result.

Based on the principle of placement on the underframe, sinks are divided into overhead and built-in. The surface of the washing panel can be located above the plane of the countertop, be flush with it, or be below the level of the desktop. In any case, the bowl under the mixer should be installed between the sections of the set to place dirty dishes and for cooking and serving dishes.

The cabinet on which the overhead sink is mounted is often a separate element of the kitchen interior. Mortise and integrated sinks are mounted into the continuous surface of the desktop of the floor-standing modules of the sets.

Installation of an overhead washing panel

Sink connection diagram: 1 – mixer pipe; 2 – gasket; 3 – fixing nut; 4 – flexible hose; 5 – pipeline supply; 6 – overflow hole; 7 – combined drain; 8 – drain device; 9 – compression ring; 10 – compression coupling; 11 – double-turn siphon; 12 – drain pipe.

Overhead types of sinks are easier to install than others. This is the traditional way of installing dishwashing equipment. In the kitchen interior, it is a free-standing cabinet with a sink, complemented by a panel for storing washed kitchen items.

The panel is fixed on the cabinet using fasteners in the form of brackets or is pushed onto the base into the grooves of the cabinet using special slides.

The sink kit may include an adhesive tubular seal that is inserted into a groove on the panel. The joint between the cabinet and the washing panel is coated with silicone sealant to protect against moisture penetration.

Rubber seals do not adhere tightly to the joining surfaces and have a short service life. More often they are replaced with a moisture-resistant sealant; it tightly fills the gaps and retains its properties for a long time when dry.

The underframe usually does not have additional internal elements; this provides access for repairing supply pipelines, cleaning the siphon and sewer pipes. Sometimes supporting bars are attached under the overhead sink, reinforcing the strength of the structure.

Before attaching the sink to the countertop, the mixer, water supply hoses and siphon are installed. The overhead sink is secured with L-shaped fasteners with an oblique slot. 4-5 such elements are installed. Self-tapping screws are screwed into the mounting points marked on the inner surface of the cabinet. They should protrude 5 mm from the walls of the underframe. It is better to screw in the screws with a screwdriver; if you use a screwdriver, the tabletop may be damaged.

During installation, the fastening grooves are placed on the screws and the sink is moved until it is firmly fixed to the overhead sink. Then the screws are tightened and the protruding sealant is removed.

Installation of a mortise sink

To prevent water from splashing when washing dishes, choose a deep sink and install a low tap.

The sink is installed in a pre-cut hole in a solid countertop. Moreover, the sink itself can be made of various materials: stainless alloy, earthenware, porcelain, etc.

To insert a washing container, you will need some tools and additional materials:

  • jigsaw with a fine-toothed file;
  • drill, screwdriver;
  • pencil, ruler, tape measure;
  • self-tapping screws, silicone sealant;
  • wrenches for installing the mixer;
  • sandpaper, construction knife.

The contours of the installed panel are marked with a pencil, turning it over and laying it on the countertop. The distances from the front and rear edges of the latter are at least 5 cm. Then the location of the bowl relative to the edges of the panel is measured. The outline of the hole cut for the sink appears along them.

The bowl can be of various shapes, so it is necessary to transfer its geometric parameters to the surface of the tabletop as accurately as possible. Manufacturers of mortise sinks often include a template with the kit, according to which the shape of the hole is drawn.

The cutting line should extend outward from the sides of the bowl by about 1 cm. A hole is drilled at one of the points on the contour to insert a jigsaw blade. For a rectangular bowl shape, holes are drilled in the corners of the intended contour.

Painting tape is glued to the outside of the outline. It will protect the surface of the tabletop from damage by the jigsaw foot when cutting. On a removable tabletop, the material is sawn with a jigsaw from the front side, so the surface cladding is less damaged. In the process of cutting the opening, self-tapping screws are screwed into the cut to a small depth so that the inner part does not fall out during operation. The sector to be removed can also be secured from below with support.

The edges of the tabletop along the saw cut are covered with silicone sealant to protect the material from moisture penetration. The sealant is also applied under the edges of the panel along the drawn contour. A sink with a built-in faucet and siphon is inserted into the prepared opening and secured to the countertop with clamps included in the plumbing kit. All that remains is to connect the mixer to the water supply and drain the sink through a siphon to the sewer.

A kitchen sink should be able to withstand absolutely everything. Hot pots and pans, cleaning supplies, ice water and more. Finding one is very difficult. A stainless steel sink is called eighteen by ten. This is the percentage of chromium and nickel that is part of stainless steel. This sink is resistant to corrosion, temperature, household acids and detergents.

Sinks can be mortise or overhead. The first ones cut into the tabletop, the second ones are simply placed on the furniture like a lid.

Overhead sinks are considered the most budget-friendly and easiest to install.

Mortise ones are installed directly into the tabletop, for which you need to cut out the corresponding hole

Undermount sinks mount below the countertop for superior sealing and appearance.

The choice of coverage is small. Either mirror or matte. Decorated stainless steel differs from smooth steel in being thicker, less noisy and more durable. In general service. A minimum of scratches is guaranteed if the wash meets the state standard. It is recommended to check the quality of your purchase using a magnet. High-quality stainless steel does not attract him. A high-quality alloy sink will cost no more than five thousand rubles. This is one of the cases when the price better matches the quality.

The metal sink fits most interiors, is simple and reliable in operation, and easy to clean.

A porcelain stoneware sink will cost about twelve thousand rubles. But the quality of porcelain stoneware is always at the level. Shape, size, smoothness of bends - all this does not play a fundamental role in the functioning of the sink. It's a matter of taste. It was revealed that for convenience, the sink should be at least 25 centimeters in length. And at least fifteen centimeters deep. When choosing a sink, you need to carefully examine it. The enamel should be even and smooth. There should be no protrusions or depressions. It should have two holes for the mixer and drain.

The porcelain stoneware sink is durable and strong, environmentally friendly, available in a wide variety of colors and configurations, but more expensive

Methods for installing a sink into a countertop

Mounting diagram for a mortise sink

Before installing a mortise sink, you need to decide on the place where it will stand. To begin installation, measure four centimeters from the far edge of the tabletop and six centimeters from the near edge of the tabletop. Take a pencil and mark.

We use a cardboard blank to apply the most accurate outline to the base of the tabletop

To accurately cut out the gap for the bowl, apply the sink with the back side and use it as a stencil. We outline it, it turns out to be an oval or a circle. We remove the bowl and trace it again with a thicker trace. We make another contour a centimeter deeper. We cut along this trace. We make a hole for the jigsaw in any convenient place, without going beyond the contour. Cut out a circle. To ensure an even cut, we use saws with straight teeth. To prevent the sawn oval from falling through, we secure it from below with ordinary self-tapping screws.

We cut out a niche from the front side of the tabletop using a jigsaw

We install crabs on special brackets, which will cling the sink to the countertop. Before installation, install a siphon and tap under the countertop. It's much more convenient. We immediately screw the hoses onto the tap. To be safe, you can screw in a couple more screws and continue. After finishing cutting out the oval, you can dismantle it. To do this you need to hold it well. We install the sink in its place. After installation, coat the end of the cut with sealant.

We apply a layer of sealant to the edge of the tabletop (on the cut), which will protect the wooden surface from moisture penetration and prevent the wood from swelling

Can be used as a sealing method

In the future, if moisture gets under the sink, the countertop will not swell. We connect the tap. We use the siphon.

You can use special fasteners to securely secure the sink to the countertop.

The surface-mounted sink is designed for installation on standard cabinets of standard width


We install the sink carefully so as not to damage the installed siphon and mixer and not to touch the applied sealant

We connect the mixer and siphon to the pipes and check the work done

Installing a stone sink into a countertop

Scheme of inserting a sink into a countertop

Stone sinks are eighty percent stone and twenty percent bonding materials. Stone sinks can withstand heavy loads, do not conduct electricity, are not exposed to aggressive substances, and are safe for food. We measure the dimensions of the sink in the countertop using a ruler and pencil. We take the sink, turn it over, circle it.

We outline the sink with a pencil and, stepping back inward by 1.5-2 cm (depending on the size of the side of the sink), draw a cutting line

We measure the exact dimensions. Drill a hole. We take a jigsaw, install it in the drilled hole, and cut out a circle. We apply the sink, it should fit exactly in the cut place.

When everything is sawed, you can simply remove the inside of the tabletop

We coat the edges with silicone using a construction gun. Apply a thick layer of silicone in a circle. Spread the silicone while cutting with a rag or glove. We also apply sealant to the sink. After that we install it in the cabinet.

Carefully turn the sink over and insert it into the hole, being careful not to touch the sealant applied to the edges.

The hole for the mixer should be closer to the wall. We put some weight in it to press it well. Leave for twelve to 20 hours. Remove excess silicone. We connect the mixer and siphon.

We install a siphon and mixer on the sink and connect the siphon to the sewer pipe

Installing an integrated sink into a countertop

An integrated kitchen sink creates a single composition with the kitchen countertop and requires skills in working with tools, so it is better to entrust an expensive option to professionals

Such equipment is one piece with the countertop and sink. Higher demands are placed on him. These devices are thicker than conventional ones and have a longer service life. Just as for installing previous types of sinks, we make a hole in the cabinet, clearly measuring the dimensions. You can order templates for installing any sinks. So, we mark the future hole and cut it out. Sharp edges are removed with a milling cutter. The curves are then sanded by hand. Polymer glue is applied. After application, install the sink. It is fixed and left for 12 hours. Finally, the shell is additionally fixed by filling it from the bottom with quickly hardening resin. It is important that the filling compound is applied only to the side walls. Then waterproofing is done using adhesive or aluminum tape. Remove excess glue after the filling compound has hardened. Connect water and drain.

Installation of siphon and sink mixer

Scheme for assembling a sink with a siphon into the sewer outlet

Siphons have two main parts: main, small. They are collected together. A plastic nut is inserted into the small one. The rubber seal is inserted under the nut. The small part is inserted into the larger one. The nut is screwed in until it stops. But even if you tighten the nut, most of it will move a little. This is necessary so that we can place the corrugation in a comfortable position. Into the tube that is on the larger part. Next to the one into which we screwed the small part. We insert a rubber seal into the second nut. We screw the second part of the siphon into this tube, which will be attached to the bottom of the sink and countertop. Screw the nut all the way so that the rubber gasket presses well. Screw the inspection cover into the siphon. If there is a blockage, you can unscrew this cap, clear the blockage and screw the cap back on. It is easier to install the siphon before installing the sink, and not vice versa. We screw the screw into the siphon until it makes a characteristic creak. No need to twist. All that remains is to install the corrugation. To do this, first insert the nut and seal, insert it into the siphon, and screw it in until it stops. Now you can connect to the sewer from the countertop.

It is important to choose the right countertop faucet. First, you need to decide how you want to turn on the water. Turn a faucet or raise and lower a lever. Everyone can choose a suitable design for themselves. It is worth remembering that a low price and fashionable design are a sign of low-quality production. It is better to buy a simple European faucet. When purchasing it, you should take into account the quality of the water and the presence of a gas water heater in the house. Faucet prices range from the lowest to the highest. Everything depends on quality. So, let's start the installation. Turn off the hot and cold water supply taps. We screw the flax onto the threaded connections. Apply plumbing paste to the flax. After that we screw it into the water sockets.

You can use silicone sealant. This is done to protect the flax from rotting. We attach flexible hoses to the mixer. There are two of them. Place an O-ring on the base of the mixer. It must be in the groove intended for it, otherwise water will leak. Screw in the threaded pins. There may be one or two of them in the mixer set. We pass flexible hoses through the mounting hole of the sink. In this case, you need to check whether the ring gasket has moved. We fix the mixer from below. We put on the rubber seal. Using an open-end wrench, firmly tighten the nuts over the seal. The crane must not move. We connect the flexible water supply hose to the water sockets. It is important that the hoses do not twist or bend during installation. After all these steps, we check the operation of the new equipment. We open the water and check for leaks.
