Reliable fastening kitchen sink sinks to a countertop, cabinet or other structure - a guarantee of long-term operation of the plumbing fixture. It is possible to achieve rigid fixation of the product only if you approach the process correctly, from the point of view of using an installation technique that corresponds to the model of the sink being installed. Therefore, the fastening for the sink to the countertop, cabinet or console is determined by the model of the plumbing fixture.
Types of sinks for washing
The range of kitchen sinks is represented by a huge assortment household appliances, differing not only in size and design, but also in the installation method and fastening. Thus, according to the installation method, there are such models of kitchen sinks as:
- Tabletop. These sinks are installed on top of countertops kitchen set, to which they are attached at the level of the siphon of the drain structure. This type of sink is used extremely rarely in kitchens. In bathrooms, these sinks are found as premium appliances. Therefore, their price is appropriate.
- Invoices. Devices of this type are installed on floor stands. The design of the sinks contains sides that serve as supporting planes. The device is placed on them, resting on the upper ends of the cabinet walls. Most often, these models are made of stainless steel, hence low price products.
- Mortise. Structurally, a device of this type is “recessed” into the countertop of the kitchen unit, to which it is attached from the reverse side of the plane with special fasteners. The installation process involves cutting out a part of the countertop exactly to fit the size of the sink.
- Under-table. Such sinks are installed just below the front surface of the countertop. These models are usually placed in countertops made of stone (natural or artificial). To secure them, special brackets are used, and the ends of the appliances are treated with a special adhesive composition, which not only glues the sinks to the countertop, but also creates a tight seal between the planes.
- Integrated. Basically, such sinks are made of synthetic stone, less often of stainless steel. The main installation condition is the minimum gap between the appliance and the countertop.
Attention! Only professional plumbers install underbench and integrated models. This is due to the fact that the installation of such sinks is a complex process, which is based on an exact fit to the countertop. Therefore, it is better not to carry out such installation yourself.
Installation technologies
The easiest installation method is to install an overhead model.
- The floor cabinet of the kitchen set is aligned in a horizontal plane using a short building level.
- If the mounting dimensions of the plumbing fixture correspond to the installation parameters of the cabinet, then installation and fastening of the first is carried out on silicone sealant. To do this, the upper surfaces of the ends of the cabinet, on which the sink is installed, are treated with sealant. It is pressed harder against the ends, for which some weight is placed inside the bowl. After 12 hours, the device is connected to the water supply and sewer networks and functions in the desired mode.
- There is a so-called standard mount. These are special brackets made of metal or plastic. They are installed on the inner walls of the cabinet using a self-tapping screw, which is not fully screwed in at first. A bracket is put on it, pressing the top shelf of the sink to the ends of the cabinet. By moving the bracket along the direction of the bevel angle, the sink is tightly pressed against the cabinet walls. After this, the self-tapping screw is screwed in completely. Plumbers advise that all work on screwing in fasteners be carried out with a screwdriver, and not with a screwdriver or drill. This is due to the fact that strong pressure on the thin metal of the sink leads to its deformation. The photo below shows this option.
- Almost the same option as the previous one, only instead of brackets for attaching the sink, wooden blocks and furniture corners. The sink is placed on bars, which are pressed from above with your hands, and the corners are installed on the block and the wall of the cabinet. The connection is made with self-tapping screws.
Installation of a mortise structure
First of all, a cutout is made in the countertop for the sink. To do this, use the template that comes with the sink. If there is none, then make it yourself. To do this, the sink is turned over and placed on a cardboard sheet. A line is drawn along its perimeter to indicate the shape of the hole. It can be round or rectangular.
Next, the same line is laid inward from the drawn line, showing the shape and dimensions of the landing area. Application distance is 1-2 centimeters. A hole in the cardboard is cut along the second line. After which the template is applied to the countertop at the exact location of the plumbing fixture, an outline is made on the surface, along which holes for the sink are cut.
The easiest way to cut is to drill many through holes around the perimeter of the marked line with a small drill with a diameter of 6-8 millimeters. A jigsaw blade is inserted into one of them, with which the material is cut around the perimeter. If the countertop is made of laminated chipboard, then there is no need to make a lot of holes, since this is a rather soft base, and a jigsaw will easily cut it.
Next, all cut planes are treated with silicone sealant, and butyl tape is laid on top of the tabletop around the perimeter of the cut hole. Both seals are designed to seal the joint and perform additional functions waterproofing. Now the most important point– fastening the sink from below. For this, a special metal bracket is used, consisting of two parts: a clamp and a holder. The first one has teeth at the end, which, when pulled together, will cut into the tabletop material and prevent the fasteners from moving. The other end is installed in the side of the sink, holds it, and when tightening the screw, presses the product to the plane of the table.
Both parts of the fastener are connected to each other with a screw, often spring-loaded. By screwing or unscrewing the screw, the clamp is strengthened or loosened, respectively. In this case, the connection between the two parts is hinged, that is, the lower clamp rotates relative to the upper holder, which simplifies the installation of the fastener.
The bracket is made of metal: stainless steel, galvanized. Today manufacturers offer fastening element with plastic inclusions. It is clear that hardware stronger. As in the case of overhead sinks, all threaded fasteners are screwed in with a screwdriver.
Rules for installing stone sinks
Sinks made of stone or granite and quartz agglomerate are in great demand today. They have heavy weight, therefore, during the installation process they have one important advantage over other models: pressure on the countertop, which ensures a minimum gap between the planes of the sink and the table. Therefore, the main thing is to accurately align the surface of the kitchen countertop in a horizontal plane. Then all cut planes of the hole for the plumbing fixture are treated with silicone sealant or any other similar material. The main task is to carry out thorough waterproofing.
After this, the sink is installed in the hole and pressed. Plumbers recommend immediately checking the horizontal position of the installation. building level. After 12 hours, the device can be used, but first it will have to be connected to communication networks. There are no fasteners, the sink will stay firmly on the countertop due to its weight and sealant.
Conclusion on the topic
The question of how to properly secure a sink to a countertop is asked quite often. Home craftsmen are looking for simple but effective solutions with which they can carry out this installation process themselves. In any case, the main requirement for installed sink– this is a rigid and reliable fastening.
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 to install 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. In marked on inner surface Self-tapping screws are screwed into the cabinets and places for fastening. 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. In this case, 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 rectangular shape Holes are drilled in the corners of the intended contour.
By outside masking tape is glued to 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 inner part did 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. The sink with built-in faucet and siphon is inserted into the prepared opening and secured to the countertop with clamps included in the kit. plumbing fixture. All that remains is to connect the mixer to the water supply and drain the sink through a siphon to the sewer.
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, stainless steel sinks are popular for kitchens today. 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.
Washing – indispensable attribute kitchens. You can easily install it yourself - you do not need to have 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.
You can attach a sink with sealant without additional equipment if it is 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 will pay special attention to it later);
- Masking tape;
- L-shaped corner.
The above items are also suitable for installing a sink on a countertop.
But experienced craftsmen All you need is 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 tool provides additional fastening sinks 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.
- Carry out plumbing work to connect the water supply and drainage in the kitchen.
Take care of the work being carried out accurately and reliably.
- 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 ordering kitchen furniture the need for a hole in the countertop to install plumbing fixtures 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.
- From the contour with outside Apply masking tape so that the surrounding surface 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 damaging it. appearance furniture 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.
Today there is a wide variety of all kinds of mortise (built into the countertop) kitchen sinks made of different materials having various shapes and colors. The most popular, inexpensive and at the same time durable type of kitchen sink can be considered stainless steel sinks. Let's look at how to install it with your own hands, using simple household power tools. kitchen sink made of stainless steel. Absolutely any mortise sinks are installed using the same principle.
We will install the sink in a countertop made of chipboard, covered with plastic on top - the most common type kitchen countertop. If necessary, e embed the sink into a countertop made of another material (for example, artificial stone), you need to follow the recommendations of the countertop manufacturer. There are also overhead sinks that are simply put on (placed) on top of the cabinet; such sinks are considered obsolete and are used extremely rarely; they will not be discussed in this article.
To install a kitchen sink, we need:
- Pencil, tape measure, ruler, construction angle, Phillips screwdriver, sharp knife.
- Jigsaw with file type Bosch T101B orT101BR.
- Electric drill with a metal drill with a diameter of 10-12 mm.
- Several self-tapping screws 16-30 mm long.
- Silicone colorless sealant (universal or plumbing).
FilesBosch T101B (top) andBosch T101BR (bottom).
They differ in the direction of the teeth: straight andthe opposite(reverse) respectively.
Marking.
Accurate marking is the key to successful installation. To begin with, you need to decide on the axis of symmetry, that is, symmetrically to what the sink will be installed. Typically, the line of the center of the sink bowl (for a round one - its diameter) goes along the center of the cabinet above which the sink is installed. Other installation options are possible, depending on the specific case (kitchen set configuration). As a rule, the distance from the front edge of the tabletop should not be less than 50 mm, and from the rear edge - less than 25 mm. However, these figures cannot be considered universal, and depending on the size of the sink, as well as the features of the insert, the figures may be different. With a pencil we draw two perpendicular axes on the front surface of the tabletop, indicating the center of the bowl and mark the boundaries of the sink (left, right, top, bottom).
Indentations from the edges of the tabletop.
Place the sink on the front surface of the countertop with the bowl facing up and align the sink relative to the markings made. Carefully, without moving the sink from its place, outline the outer contour of the sink with a pencil. We remove the sink from the countertop.
Depending on the manufacturer, the stainless sink kit (d Most sinks made of artificial stone do not have such fastenings.) may include metal, or plastic fastenings. If possible, preference should be given to metal (all-metal) fasteners, as they are more reliable. Before installing the fasteners on the sink, it is recommended to disassemble them (by separating the parts mounted on the sink and on the countertop from each other). By clicking, the parts of the fastenings are installed on the sink into the corresponding metal eyes so that the fastenings protrude minimally outward - “looking” into the inside of the sink.
Part of the fastening installed on the sink.
We accurately measure the width of the sink side (the distance from the outer edge of the sink to installed fasteners), taking into account the protrusions of the fasteners. As a rule, the width of the rim of a stainless steel sink ranges from 10 to 15 mm.
The sink is ready to be outlined on the countertop.
Parallel to the outer contour of the sink previously drawn on the countertop, draw by hand (or using a ruler to control accuracy) another contour - the cutting line - inside (closer to the center of the sink), indented by the width of the side of the sink minus 1-2 mm. The sink should fit freely into the future hole, allowing up to 2 mm of play on each side.
Marking the cutting line.
Cutting a mounting hole in the countertop.
In one (with round sink) or in several places (in the corners of the marking, with a rectangular sink) of the countertop, we make a through hole with a 10-12 mm drill so that the future hole is close to the cutting line, but does not touch it (it is closer to the center of the sink). It is necessary to drill from the front surface of the tabletop! We get a hole(s) for the file to enter.
Using a jigsaw, exactly along the cutting line, we make a closed cut. To keep the inside of the tabletop in place (not fall down), you need to screw screws into the gap from time to time, which will act as temporary fasteners (wedges). We insert the sink into the countertop, check that the cutout is made correctly (the sink should fit freely with a slight play), if necessary, perform additional trimming with a jigsaw.
Close-up of the hole.
Small chips of plastic are acceptable.
To avoid chipping at all, you need to use a file.T101BRwith reverse direction of teeth.
After sawing is completed and the unnecessary (inner) part of the tabletop is removed, it is necessary to clean the cut from dust and carefully cover it with silicone sealant (using a small rubber spatula), this will prevent the tabletop from swelling when water gets in. You also need to lubricate the plastic chips that formed during sawing. There is no need to get too carried away - there is no point in covering the cut with a thick layer of sealant.
Applying sealant to the cut.
We glue a sealant made of foamed polyethylene (included with the sink) to the side of the sink around the entire perimeter. If, after gluing the seal, it protrudes beyond the outer contour of the side (rises above it) by more than 1 mm, then the seal must be trimmed with the sharp tip of a knife, otherwise there is a possibility that the fasteners will not be able to fully press the seal and press the sink to the plane of the countertop . If we are dealing with a sink made of artificial stone, then there is no need to glue any seals.
Using a clean cloth soaked in gasoline or acetone, degrease the surface of the seal and the line of contact of the seal to the countertop. We apply the sealant to the sealant in a continuous strip, not being carried away by the thickness of this strip (it is assumed that the sealant is glued flush with the protrusion of the side). In practice, you can find a way to install a stainless steel sink without using a sealant at all; in this case, the entire space designed for inserting the sealant is filled with sealant. This is acceptable, but undesirable for several reasons: high consumption of sealant (as a result, long drying time), difficult control of filling the seam, labor-intensive process of dismantling the sink in case of unsuccessful installation. An exception is the installation of a sink made of artificial stone; such a sink is mounted only on sealant.
Applying sealant to the seal.
Sink fastening.
We insert the sink into the hole in the countertop and align it with the markings (the markings must be applied so that they are partially preserved after cutting out the countertop). We take two or four fasteners and, equidistant from each other, pre-fasten the sink (without fully tightening the fastenings), constantly monitoring its position relative to the markings. Attention! Tightening the sink fasteners must be done manually, without using a screwdriver, as the threads in plastic parts are easily torn off!
We turn the tabletop upside down (for convenience), install all the fasteners, and finally tighten them, trying to do this evenly and consistently. To ensure that the sharp spikes of the fasteners penetrate the tabletop in the best possible way, you can sharpen them with a file and/or lightly tap them with a hammer while tightening them.
Assembly on the sink. By tightening the self-tapping screw, the sink is pulled to the countertop. The sharp ends of the metal part of the fastening must be securely fixed in the tabletop.
Tighten the fasteners with a screwdriver.
The fastening is tight. It is recommended to lightly tap the fastener with a hammer so that the sharp ends cut deeper into the tabletop.
Let's look at the result of the work: the sink should be pressed along the entire perimeter to the surface of the countertop, installed along the marking lines. Indirect confirmation of the complete fit of the sink can be the squeezed out sealant. Use a cloth to wipe off excess sealant and markings from the front surface of the countertop. Allow the sealant to harden overnight. If the sink is made of artificial stone and is not equipped with fasteners, it is necessary to ensure that it is completely immobile while the sealant is curing.
The sink is well pressed to the countertop. The sealant squeezed out slightly.
Installing a built-in kitchen sink is a responsible undertaking. Poor installation of a sink can not only spoil the appearance of the kitchen, but also lead to rapid failure of the countertop due to water penetrating under the sink onto the cut of the countertop. Primary importance should be given to sealing the sink-countertop joint; do not rely on well-executed processing of the cutout end.
The kitchen sink is strategically important role, so you need to choose and install it yourself correctly.
Choosing a kitchen sink and preparing for its installation
Before deciding how to install a sink into a countertop, you need to decide on the choice of product. The best option- connecting a deep sink and a faucet that is not too high - in this case there will be a minimum of splashes when washing dishes. The sink should be deep so that it is convenient to wash large pots or stack plates after a family dinner.
The material also matters - it is easiest to connect a traditional stainless steel sink yourself. Good decision enamelled steel will also become.
Installing a kitchen sink with your own hands requires the following tools and materials:
- Sealant;
- Self-tapping screws and screwdrivers;
- Jigsaw;
- Fasteners (as a rule, they are included with the product).
Advice! Before fixing the kitchen sink, you should carefully treat all seats with sealant. This will ensure high-quality waterproofing and protection of the chipboard from damage due to high humidity.
Types of kitchen sinks
Installing a kitchen sink with your own hands can be done using various technologies. The installation method is selected depending on the type of sink structure:
- Invoices are considered the most budget-friendly and easiest to install with your own hands. The sink is placed on a separate cabinet. The disadvantage of this option is that there are gaps between the sink and the cabinet.
- Mortise ones are installed directly into the tabletop, for which you need to cut out the corresponding hole.
- Undercounter sinks belong to the more expensive segment; they are mounted below the countertop, thanks to which they provide excellent sealing and appearance.
Installation of an overhead sink
The affordable overhead (built-in) sink is made of stainless steel. It is mounted on a separate module and covers its entire top part. It's very easy installation– special L-shaped elements with an oblique slot are used for fastening. About 4-5 such fasteners are provided for one sink.
Advice! The connection of the mixer is carried out before the installation of the sink (the sink is already installed with installed equipment) – otherwise it will be inconvenient to do all this at subsequent stages.
How to attach an overhead sink with your own hands:
- You need to attach the L-shaped fasteners to the cabinet from the inside and make notes;
- Screw the screws in the marked places. It is important to choose short 15 mm screws and screw them in so that no less than 5 mm remains above the mark;
- Cover the end of the drawer with sealant - it will protect the furniture and additionally glue the sink;
- After this, the sink is installed on the screws screwed into the cabinet and moved until it fits completely;
- Then the fasteners are fixed, the excess sealant is wiped off, and you can begin connecting the sink to the water supply and sewerage system.
Inset sink type - step-by-step installation
Of course, it’s easier to install an overhead sink yourself, but a built-in model provides a greater level of tightness and looks very neat on a cabinet with a common countertop. The question of how to embed a sink into a countertop is solved quite simply - you just need to make the right hole for the sink.
Installing a sink into a countertop is carried out according to the following algorithm:
- The location of the sink is found on the countertop and the shape of the future hole is determined. To do this, turn the sink over and trace the contour directly on the countertop or on cardboard. If you have chosen a product of complex shape, then a ready-made template is most likely already included in the kit - this will help you cut out the desired hole;
- The finished template is applied to the tabletop at a distance of about 7 centimeters from the edge and begins to be cut out. To do this, step 1.8 cm deep from the edge of the template, leaving support for the sides of the sink;
- On the cutting line, first make a hole with a drill, and then cut out the outline with a jigsaw. The lower part of the tabletop is secured so that it does not fall out during cutting and damage the edge of the remaining surface;
- Sealant is applied along the contour of the cut. It also covers the lower joints of the sink;
- You can start attaching the sink - it is pressed with the included clamps;
- After the excess sealant has been removed, you can begin connecting the communications.
Installation of the sink flush or below the level of the countertop. Unusually shaped sinks
An undermount sink can be mounted flush with the countertop - however, this is a labor-intensive process that requires experience, since it involves removing the layer of countertop under the edge. The depth of removal is equal to the height of the side with a layer of sealant.
If you decide to install and connect the sink so that it is below the table level, you will have to resort to the services of specialists. After all, this installation method is chosen for expensive structures - not made of steel, but of natural, artificial stone. In this case, special tools are required for fastening - for example, a jigsaw and diamond-coated saws. Indeed, in such sinks there may not be a hole for draining water - complete sawing of products is not carried out in industrial conditions. Shells from natural materials secured with special mounting adhesive.
As for sinks with unusual shapes, they come with a paper template from which the installation hole can be cut.
Do you want to connect the sink yourself correctly? Don't forget 3 more points:
- It is better to replace rubber seals with silicone sealant. Rubber will not provide a tight fit and does not have a sufficient service life, while the sealant will fill all the gaps and cracks;
- It is better to connect sinks made of natural or artificial stone together to prevent falls and damage;
- Fastening the sink to the countertop or module with self-tapping screws is carried out exclusively by hand. Using a tool may create too much tension, which may damage the structure.
Main rules of connection
When the installation work is completed, you can connect the sink. To do this, the hoses through which cold and hot water, are connected to the general water supply system.
Advice! Connection requires use rubber gasket For better sealing junction points.
After the hoses are secured, the connection is made in the following sequence:
- A siphon outlet is inserted into the sink (it is better to use S-shaped designs, since the bottle one gets clogged too quickly);
- A pipe (angular rigid or flexible corrugated) is added to the siphon;
