Preparing tools and dismantling the old bathroom sink

Installing a new bathroom sink with your own hands requires the following tools:

1. Perforator or impact drill.
2. Special drill for concrete.
3. Screwdriver or screwdriver set.
4. A set of wrenches.
5. gas key.
6. Dowel-screws.
7. silicone sealant.
8. windings.

Before you start installing a new sink in the bathroom with your own hands or any other work related to the plumbing, you must definitely turn off the water.

First of all, unscrew the nut holding the mixer and disconnect the rigid or flexible hose. Disconnected pipes are best released into a bucket, because. they may have runoff. After that, you can remove the mixer. Next, you need to disconnect the siphon connecting the sink in the bathroom to the sewer. Carefully loosen the bottom nuts and remove the siphon.

If you want to replace old components, then the siphon must be disconnected from the drain, and the remaining hole should be plugged with a rag or cork so that unpleasant odors do not enter the room. After that, the sink should be removed from the mounts and discarded (at the discretion).

Do-it-yourself installation of a new sink in the bathroom: what should be considered?

Installing a new sink in the bathroom with your own hands requires taking into account many characteristics, including dimensions and type of product.

According to the design and type of installation, the following bathroom washbasins are distinguished:

• sink on a shelf or cabinet;
• shell-tulip;
• washbasin on brackets;
• washbasin on a pedestal.

Installing each type of bathroom sink with your own hands has its own characteristics. If you are not sure that you can do the installation correctly with your own hands, it is better to immediately contact the professionals.

Sink-tulip and washbasin on brackets: installation procedure

Do-it-yourself installation of a tulip sink for a bathroom does not have fundamental differences from the installation of other types of products. The only feature of this type is the installation of the legs on which the bowl fits. The installation height of the washbasin must be selected according to the height of the bottom leg. Together with the washbasin, a faucet is also performed. The installation of these devices may require the use of special tools.

Another feature of this type is that the drain will be located inside the leg. Therefore, all parts must be carefully fixed and insulated so that in the future you do not have to dismantle the product several times and constantly be afraid of leaks.

Do-it-yourself installation of a sink on brackets is not a very difficult undertaking. Installation of such a product is carried out after completion of all finishing works. First you need to make the correct markup and only after that proceed to the installation of fasteners. First you need to draw a horizontal line at the required height (usually 85 cm from the floor). After that, stepping back to a distance equal to the thickness of the washbasin from the side adjacent to the wall, you should draw a second line, which will become the basis for the brackets.

Measure the width of the sink, attach the brackets to the wall and mark future holes. At these points it is necessary to drill holes and install dowels. Fixings are screwed onto the dowels, after which the sink is installed on them. It shouldn't move or wobble. Only after the bowl is stable and snug against the wall, you can drain. An alternative to this method is to mount the washbasin with your own hands on hanging shelf or cabinet.

Installing a washbasin on a cabinet and pedestal

Scheme of connecting a bottle siphon.

If it is carried out on a curbstone, then the countertop becomes at the same time a holder for the bowl. The washbasin is either top-mounted or completely built into the hole. In both cases, the drain is hidden under a shelf or in a cabinet. Such a sink is installed in accordance with the above technology, however, the advantage is that for this method created many models of products of non-standard design. Such models can have standard and extraordinary forms. Designer sinks can be made of glass, have a spherical or cubic shape, and you can decorate such a product with your own hands, using smalt, stones and everything that your imagination suggests for this.

If the sink is mounted on a pedestal, then it all depends on the type of bowl itself. Sometimes the washbasin is mounted on brackets, and the pedestal performs a purely decorative function. In other cases, the bowl of the shell rests on a pedestal and seems to stand on it. In this case, the sink can be located at a sufficiently long distance from the wall. If the structure will be adjacent to the wall, then it must first be mounted in the right place and the places for mounting the bowl must be marked. In this embodiment, fastening with brackets is used, the execution technology of which was described above.

Be sure to attach rubber washers to the screws. It is not necessary to tighten them very tightly - it is enough that the washbasin simply does not budge. Large forces may cause cracks to form on the bowl. When the washbasin is installed on a semi-pedestal, the outlet socket should be positioned at a distance of 50 cm from the floor. The bowl is attached to the wall, and the semi-pedestal is installed in accordance with the manufacturer's recommendations.

A washbasin is a key element of the sanitary and hygienic purpose of any home. The need to replace which may arise for various reasons. And the comfort and convenience of its subsequent operation depends on how correctly the installation of the sink in the bathroom is carried out.

Plumbing works of this level can be performed by anyone who wishes, if certain rules are followed.

The main stages of work are:

Selection of equipment for installing a sink in the bathroom;

Preliminary preparation of tools and related materials for dismantling the old washbasin and installing a new one;

Dismantling of old equipment;

Direct replacement of the sink with your own hands;

Connecting the tap and connecting it to the water supply;

Connecting the drain to the sewer;

Testing plumbing fixtures for performance.

Do-it-yourself sink installation: preparation

Installing a washbasin in a bathroom requires a well-thought-out solution, not only in terms of aesthetics, functionality, but also in terms of installation possibilities.

Currently offered the following options sinks, differing in the type of installation: mounted, built-in and on the leg.

However, it should be remembered that when replacing the sink in the bathroom, it is necessary to take into account where and how the nodes for connecting to the sewer and the location of the water pipes are located. This will minimize subsequent modifications when installing new equipment.

To "fit" a new sink in place of the previous one, you must first take measurements, which you will rely on when choosing a washbasin. The key parameters are the length, width and depth of the washbasin.

To successfully replace the sink with your own hands, you may need the following tools and materials:

A set of screwdrivers, pliers;

Special plumbing keys;

Connecting pipes;

Silicone sealant;

Spatula, bucket, rag.

Remember: do-it-yourself sink replacement begins with blocking the source of water supply.

As a rule, the main valve is located at the inlet in front of the water meter or directly under the sink itself. After closing it, make sure that hot and cold water does not flow.

Do-it-yourself sink installation: dismantling

1. To replace the sink in the bathroom, you first need to disconnect the water pipes from the faucet. Be careful, as this may result in the leakage of accumulated water. Prepare a bucket and a rag in advance.

2. Find the place where the sink drain siphon and drain to the sewer connect. Using a tool, disconnect the sink from the drain by directing the siphon socket towards the bucket.

3. Using wrench dismantle the water supply system (cold and hot flow).

4. Remove the fasteners that secure the sink to the wall.

5. Using a spatula, carefully remove the old sealant and separate the sink from the wall and contact surface.

6. Remove the old sink and clean the installation area for the new sink.

To competently replace the sink with your own hands, consider the size of the new equipment: analyze whether there is enough space to install it in the old place. It is convenient to use a specially made template or just a tape measure. Often, ready-made templates for a sink cutout are included with the sink. Perhaps, given the new dimensions, the replacement of the bathroom sink will require additional work.

In case of installation of faucets and a faucet from an old washbasin on new equipment, remove the faucets and fix them on the new sink, do not forget to treat the joints with sealant.

Usually new sinks come with clamps and screws. The crane is completed with drain. If you don't have them, buy optional equipment separately. Make sure that the supply pipes match the faucet and fittings under the washing surface.

Do-it-yourself sink installation: INSTALLATION

1. When installing the sink in the bathroom, you must first apply a layer silicone sealant on the lower base of the upper "lip" of the washbasin, and then fix it in place of the old equipment, in the recess on the wall. Fix the sink in the hole, remove excess silicone.

In the event that the installation of the sink in the bathroom requires fastening to the wall or a stone counter is used, then you will need to pre-prepare the areas for fixing the equipment - drill holes in the wall. This requires diamond-tipped drills.

2. Fasten the washbasin with clips, following the instructions step by step.

3. Install the drain siphon tail. If a gasket is included between the shank and the sink, then secure it with a nut, locknut and cardboard washer. At the point of connection to the sewer, an additional seal of the appropriate configuration will be required. When connecting pipes, use Teflon tape or special gaskets as a sealant.

4. When connecting a faucet to a water pipe, use hoses of sufficient length so as not to stress the connections. Tighten them with wrench. The tightening force must not be excessive, so as not to destroy the sealing gasket.

5. Treat all cracks and joints with sealant and let it dry for a day.

6. Testing plumbing for performance. Open the valve, then turn on the faucet. If minor leaks are found at the joints, tighten the fasteners tighter, but do not overdo it. If in some places tightening of the connections does not work, then the seals may have to be replaced.

If a leak is not detected and the entire system is functioning properly, then we can assume that the replacement of the bathroom sink has been successfully completed.

Regardless of the reasons, many people wonder - how? Replacing an old washbasin can take two to four hours. To independently install a new sink does not require special knowledge and skills.

Before starting work, it is important to determine in advance whether the wall can withstand the new washbasin, because it may weigh much more than the old one. If this is true, then it is necessary to use special fasteners - a supporting frame.

How to replace a bathroom sink - step by step

The process of replacing an old sink with a new one consists of several stages:

1. Wall marking. measuring tape you need to measure the dimensions of the old washbasin. When you go shopping for a new sink, it's important to have all your measurements with you.
2. Overlapping water. To turn off the water, use a wrench of the desired diameter to turn the valve located under the sink. To make sure that the water is shut off, just turn on the tap.
3. Removal drainage pipe. To begin with, it is important to put an empty bucket or a deep container under the siphon, and then loosen the bolts using an adjustable wrench (with their help the siphon is attached to the sink at the bottom). The siphon must be carefully removed from the washbasin.
4. Disconnecting the hot and cold supply hoses cold water wrench.
5. Removal of fasteners of old plumbing. The screws are removed with a flathead screwdriver.
6. Removal of adhesive material. The adhesive or putty is removed from the wall with a conventional spatula.
7. Installation new plumbing. The sink must be installed on a flat surface, so it is necessary to clean the tile, removing the remnants of adhesive and sealant.
8. Removing the drain and faucet from the old plumbing (if you plan to install a new faucet).
9. Fastening new fasteners to the wall. After all parts of the sink have been attached, it is necessary to cover the joints of the faucet with sealant.
10. Application of silicone sealant to the rim of the bottom of the washbasin. Excess sealant can be removed with napkins or a cloth.
11. Fixing the sink to the wall with screws. It is necessary to climb under the sink and use a screwdriver to fasten the screws in the plumbing fixtures.
12. Connecting hot and cold water hoses with a wrench. The siphon under the washbasin must also be secured with a key, while it is important not to overtighten the valves.
13. Checking the water supply. Do not remove the bucket from under the sink until you are sure that the water is not leaking. If the siphon leaks, then it is necessary to turn off the water and wrap the thread of the hose with fluoroplastic tape.

The arrangement of the bathroom is a responsible event that raises a lot of questions from the owners who install the equipment on their own. A rich selection of sinks provides consumers with the opportunity to select equipment for any interior.

We will talk about how the sink in the bathroom is installed in accordance with building codes and sanitary and hygienic requirements. In the article presented by us, examples of mounting the built-in and console versions are considered. Based on our recommendations, you can easily cope with the work yourself.

The method of installation of sanitary equipment is determined by the type of sink. Leading manufacturers produce several types of sinks.

The most widespread are four types of sinks, differing in the method of installation:

1. Embedded. They are installed in the countertop cabinets, tables or any other flat surface. Such models are convenient in that they allow you to completely hide unattractive communications behind the furniture doors.
2. Console. They represent suspended structures, which are fixed on the wall using a ready-made installation system. Models of this type look stylish and modern.
3. With a pedestal Models of the "tulip" series have decorative element in the form of a pedestal on which a massive bowl rests. The drain fitting is hidden inside the support.
4. With half pedestal. Models of this type are also equipped with a pedestal. But he does not rest on the floor, but on the wall. Thereby wall models look more elegant. The installation of such equipment is complicated by the need to bring the drain to a given height.

Built-in sinks can be mounted on top of the countertop, fixed with sides around the perimeter of the base, or built into the structure from below.

Regardless of the installation method, the bathroom sinks on sale are very diverse in shape and configuration: oval, round, cubic

In bathrooms where it is not possible to install a countertop standard width, it is convenient to use semi-embedded models that simply go around the edge of the countertop.

The only caveat - when installing such plumbing, you will need to install an improvised cabinet, behind the walls of which all communications will be hidden.

Console and built-in models are chosen by the owners of small-sized bathrooms, in which every centimeter of area is “under calculation”

How to dismantle old equipment?

To dismantle a device that has served its time, you must first turn off the water, then loosen the mixer. To do this, unscrew the nut fixing it. The equipment is disconnected from the supply pipes, carefully removed and cleaned.

Having unscrewed the taps, it is necessary to make sure that stagnant or water coming from the pipeline does not leak through the control valve

After that, the drain elements are dismantled:

1. Nuts are unscrewed from the lower outer part of the plumbing element.
2. Disconnect the siphon glass from the drain outlet, free it from water and clean it from accumulated dirt.
3. Remove liquid from drain and manually unscrew the lock nut by turning it counterclockwise.

If the siphon is to be replaced during the dismantling of the equipment, it must be separated from drain pipe. To do this, unscrew the lock nut located at the junction of the drain and the water seal, carefully lift the drain and drain the siphon.

Before removing the drain with the installed gasket, the wedge-shaped spacer washer must be pushed aside. At the final stage, it remains only to pull out the outlet pipe with the attached siphon from the sewer socket.

So that the accumulated water does not drain to the floor when disassembling the elements, it is advisable to install a bucket or any storage container under the siphon

After completion of work, to prevent the spread bad smell, the hole of the sewer pipe is carefully closed with a cork or a piece of fabric folded several times.

If you have to dismantle a sink attached to the wall using combined stands, you should look for attachment points on the sides, closer to the bottom of the washbasin. If the bowl does not have a floor support, when unscrewing the nuts, the sink should be held with your hands so that it does not fall to the floor under its own weight.

Cantilever washbasin installation procedure

There is nothing complicated in installing a sink in a bathroom without resorting to the services of professionals. The main thing is to strictly adhere to the installation technology, which includes several main stages.

Properly installed sink installation is the key to the normal functioning of plumbing equipment and ease of use by household members, as well as the absence of regular repair work.

To perform the work you will need the following tools:

• electric drill;
• drills for concrete;
• building level;
• tape measure and a simple pencil;
• spanners;
• expansion dowels;
• building glue;
• self-tapping screws;
• FUM tape.

Making holes for fasteners

For installing brackets in the outer supporting walls of the bowl with back side turn the item upside down. The plumbing fixture with installed brackets is moved to the horizontal line drawn. Along the drawn line, the places for mounting the fasteners are marked.

At the intended points of future fasteners, holes with a diameter of 1-2 mm are made using an electric drill. smaller size prepared dowels. The fixing screw should be difficult to enter into the “nest” made.

Small portions of glue are poured into the holes to strengthen the strength of the joints, then bushings are driven in and support brackets are installed for mounting the bowl

Expansion dowels of nylon or other polymeric design are driven into the prepared holes, self-tapping screws of the appropriate diameter are screwed into them. Then screw the brackets themselves.

A little trick: so that at the time of making holes, the drill bit does not slip on the tile, sticky mounting foam is glued to the treated area.

Mounting the sink bowl

After tightening the self-tapping screws, check the strength of the fasteners. A sink is put on top of the mounting studs. Sealing inserts and washers are put on the screws, and then the structure is carefully tightened. The washbasin is additionally fixed with a sealant or clips.

When tightening self-tapping screws, it is not necessary to apply special efforts, otherwise the surface of the washbasin may be covered with a scattering of cracks or split

The task of the master when twisting the washers is to achieve an effect so that the bowl does not sway. The attachment points are decorated by putting on plugs. To prevent the appearance of mold when water enters the gap between the sink and the wall, this place must be additionally coated with silicone plumbing sealant.

Connecting the siphon to communications

Installation of the siphon begins with fixing the release. To do this, a grid, a rubber or silicone gasket and a clamping screw are installed in the drain hole. The presence of a gasket is mandatory, since it ensures the tightness of the connection.

When installing gaskets, it is important to control that they fit as tightly as possible, without any gaps and displacements, fit the washbasin drain

After making sure that the gasket is installed correctly, tighten the clamping screw, thereby connecting the outlet to the siphon. After that, the end of the outlet pipe, made of hard plastic or corrugated hose, is connected to the sewer socket.

When connecting to the sewer, it is mandatory to use seals, which can be rubber gaskets or cuffs for corrugations.

Faucet installation process

It is better to install a plumbing fixture before fixing the washbasin to the wall. After installing plumbing, connecting it will be much more difficult. For this purpose, the mounting studs and flexible hoses that come with the kit are screwed into the mixer.

With the help of this eyeliner, they connect to the water supply. To seal the joints in order to prevent possible leaks, the FUM tape is wound.

Water supply hoses are inserted into the hole, having previously put moon-shaped gaskets and washers on them from the underside.

One end of the hose, equipped with fittings or fasteners, is connected to the mixer, and the other to water pipes. If the diameters of the pipe and the outlet differ, a sealing cuff is put on.

At the final stage of the connection, it remains to check the operability of the system and make sure that there are no leaks at the junctions of the pipes and cuffs.

You will find a step-by-step guide for installing a faucet on a sink in, which we strongly advise you to read.

Assembly and connection of the tulip sink

The bulk of the sink with a pedestal is distributed on a decorative support leg, however, the bowl itself is still attached to the wall. The process of installing and connecting this plumbing includes a number of traditional steps. The following photo gallery will help you get acquainted with it:

With the details of installing a tulip-type sink, the contents of which are completely devoted to this issue.

Features of mounting a built-in sink

Built-in models are cut into the countertop from below or from above.

Each installation method has its own nuances:

• When the bowl is placed on top, it will protrude from one to three centimeters above the surface.
• The lower tie-in method is preferable because during operation it is convenient to collect splashes with just one movement.

Regardless of whether the sink is completely recessed into the cabinet, or whether it will partially rise above the surface, drain valve will still be located inside the cabinet.

If you plan to mount a built-in sink, be prepared for the fact that you will need to perform the perfect processing of all joints

To implement the insert from below, L-shaped fasteners are used, and fixation is performed to the base of the support.

Marking the installation site

To simplify the marking of the countertop for the installation of a recessed sink, the use of a template will help. Many leading manufacturers include it in the kit with most built-in models.

When determining a place for installing a washbasin, two conditions are guided:

1. The sink should not be on the very edge or right up against the wall.
2. It should provide free access and ease of use.

The meaning of creation correct markup is that the washbasin is firmly fixed in the countertop, but at the same time does not fall through the hole in it.

For lack of a template, the shell is turned upside down and applied to the surface. Draw a contour with a simple pencil.

The line of the inner contour traditionally recedes to the center by 1.5-2 cm relative to the outer line; it serves as a guide when cutting a hole for the bowl

In order to correctly calculate the distance from the edges of the plumbing to the eyelets of the fasteners, measurements are taken and transferred to the circled contour. The resulting size determines the distance that should be retreated from the line in order to create an internal contour that acts as a support for the sides of the bowl.

Sawing and edging

The hole for installing the bowl is made using a jigsaw. If you have to work with a hacksaw, be prepared for the fact that you need to trim the edges.

When working with a hacksaw, in order to get a neat cut, first a hole is drilled in the region of the marking line inside the outlined contour. Its diameter should be such that the hacksaw blade fits freely.

Important! To minimize the risk of chipping on decorative coating countertops, sawing should be done slowly and without excessive effort.

The end surfaces of the created hole are treated with fine-grained sandpaper or polished with a file.

To avoid problems with leakage during operation of the equipment, the cleaned edges of the tabletop cut in 2-3 layers are covered with a sealing compound.

When choosing a sealant, it is important to focus on the type of material used in the manufacture of countertops. So for plastic and wood flooring alcohol-based sealants are used.

Installing the bowl and connecting equipment

The bowl is installed in the countertop and deepened. To ensure a tight fit, the product is rotated slightly back and forth. After that, it remains only to tighten the installed fasteners and remove the silicone with a napkin, which is squeezed out when the bowl is seated in place. The assembled and fixed structure is left for a day until the adhesive composition dries completely.

To connect the equipment, a mixer is installed in the hole, connected to the hoses and fixed with fasteners. The outlet of the siphon is brought into the sink, a pipe is attached to it, which is led out into the sewer socket.

In general, the technology and siphon of the built-in sink is almost identical to that described when installing the console model.

The specifics of assembling a complex from a countertop and a countertop sink, we recommend that you familiarize yourself with a very useful material.

When planning to install a washbasin located below the level of the table, it is better to use the services of a professional plumber. After all, this installation method is often chosen for expensive models made of natural or artificial stone.

And this requires not only to have at your disposal special equipment for cutting stone, but also to know the intricacies of working with capricious material.

Please write your comments in the box below. Tell us about how you assembled and installed the sink in the wash area in the bathroom. Ask questions, share useful technological nuances known to you, publish photos on the topic of the article.

Depending on which modification will be selected, installing a sink in the bathroom or in the kitchen involves an appropriate list of activities. After all, most modern manufacturers of sanitary equipment recommend a huge range of wash-hand basins for both the bathroom and the kitchen. If the structure is fastened incorrectly, repairs can be damaged not only in your apartment, but also in the neighbors living below you.

Before installing a sink in the bathroom, you must determine:

• what is the practicality of the material used to create the washbasin;
• what shade of the washbasin will be the most relevant in the shower room;
• which fixture for the bathroom sink is the most comfortable and ergonomic.

Types of washbasins for the bathroom according to the method of attachment

Do-it-yourself installation of a sink in a bathroom implies, first of all, an understanding of the instructional points regarding this sanitary equipment, in particular, how to fix it.

So, today there are the following types of fasteners for washbasin bowls in a bathroom or shower:

Other Important Details to Consider When Buying a Bathtub Sink

Before you put the sink in the bathroom, you need to clearly understand which particular variation of the model should be purchased (for example, with or without a pedestal), and also determine its desired scale. To do this, it is worth making preliminary measurements of the area of ​​\u200b\u200bthe room where it is planned to subsequently fix the equipment.

The configuration of the bowl can be anything, but the length is not less than 550 mm, otherwise the water from the tap will splash onto the floor.

Washbasins are produced deaf or with holes for the mixer, in this regard, you need to decide in advance on the method of attaching the latter. It is advisable to purchase it together with a washbasin, so that even before making a purchase, it is possible to diagnose the equipment for compatibility.

Another important aspect is the correspondence of the plumbing system with the fixing components of the washbasin. Complete with equipment, as a rule, a siphon is also attached, and in case of its absence, you must immediately select the optimal model.

The vending sink must be carefully checked for all kinds of scratches and chips. For example, if you purchase built-in equipment or a cup with a pedestal, then you should check on the spot how the product falls into place, and once again make sure that the pedestal has the desired height.

And the last important “trifle” - if the purchased equipment does not have fasteners, you must immediately purchase them so as not to miscalculate with the accuracy of fixing the sink and other structures to it directly on the spot.

Self-assembly

Having decided to figure out how to properly install a wall-mounted washstand bowl, with a pedestal or on a pedestal, you need to imagine the whole order necessary action. Only in this way the installation will be carried out efficiently and without problems.

First you need to dismantle the old structure, usually consisting of a sink, cabinet and other elements. Necessary:

1. Unscrew the nut, with which the installed mixer is fixed, disconnect the piping and carefully remove it.
2. Then unscrew the nuts from the underside of the washstand and disconnect the siphon from the drain outlet. The liquid must be drained from it in advance.
3. If the siphon needs to be replaced, it will need to be disconnected from the drain pipe. It is advisable to plug the water supply hole with a cork or a rag so that bad smell sewerage did not penetrate the bathroom.
4. Remove the washbasin that has served its park resource from the support (bedside tables, countertops, brackets, etc.).

The installation of the equipment itself consists of fixing the sink either on the wall of the room, or on the countertop or pedestal itself. Fixing the washbasin on the wall must be carried out with the accuracy of observing the horizontal level, while it is advisable not to tighten the bolts too tight (it is enough to fix the product so that it simply does not stagger).

It is much easier to install a washstand in a table-top rack or in a nightstand, since in this case the element is installed separately from the wall. All plumbing and drain communications are connected to the finished equipment with a pedestal.

After the sink is fully installed in the bathroom, it is imperative to open the water tap and drain the water to check the structure for leaks. If a leak occurs, then most often the cause of this is poorly tightened connections. To eliminate such a defect, you need to check the fastening sewer pipes and coat the joints with sealant.

It should be noted that there should not be gaps of more than 3-5 mm between the sink and the wall of the room. Otherwise, the ingress of water on the floor may cause the gradual destruction of the wall finish under the influence of dampness. The best solution- seal the gap with sealant in the same way as pipe joints. It must be remembered that the correct installation and daily care behind plumbing equipment significantly increase the period of its technical operation, as well as the comfort of using the installation.
