Correct installation of the washbasin: wall-mounted, surface-mounted (tabletop), floor-standing

Choosing the right washbasin in terms of size, material and shape is just the first step towards creating a beautiful and comfortable bathroom. The selected washbasin still needs to be installed correctly, and since the task is not very difficult, if you have at least minimal experience and if you want to figure it out, you can cope with the installation yourself. But the installation of different types of washbasins differs in its nuances and features that require more careful study.

Correct sink height

install washbasinBefore proceeding directly to the installation of the sink, you need to find out at what height it should still be mounted. Many do not pay enough attention to this issue, and as a result, even the most stylish and modern bathroom is often decorated with a completely non-ergonomic sink, which requires bending over to use. And if once such inconveniences can be tolerated, then day after day for several years it will be difficult to wash, brush your teeth, paint or shave behind an uncomfortable sink. That is why it is important to determine the optimal height for its location.

So, earlier there were standards that determined the location of the sink at a height of 70-75 cm. Since Soviet times, these standards have not actually been revised, but the experience of using washbasins tells us that for greater convenience it should be located a little higher. So, ergonomists have determined that the optimal height is 5-10 cm below the elbow, since in this position the cyst is most convenient. That is why there can be no question of any one figure, one height value that would suit absolutely everyone. So, with an average female height, the height of the washbasin should be about 90 cm.If there are several people in the family, then the average value is displayed, or, as in American baths, they use several sinks, and there are even sinks for children, and they can be adjusted in height …

Installing a washbasin on a vanity

installation of a washbasin on a vanity 3In the case of installing a washbasin on a pedestal, the process is as simple as possible, since the main load of the washbasin is taken over by the pedestal, therefore, fastening to the wall can be neglected. In addition, all pipes are neatly hidden under the sink, and as a result, the bath gets a nice stylish look.

It is immediately clear that if the cabinet was purchased disassembled, then it must be assembled according to the scheme that is usually attached in the kit. But now we are not talking about that, but about how to put a sink on an already assembled cabinet. The washbasin, by the way, can be recessed into the cabinet, or stand on it: from the point of view of design, there are many options, but from the point of view of technology, the set of work carried out is the same.

installation of a washbasin on a vanity unit 2So, first, a mixer must be installed on the washbasin, and it is recommended to use modern single-lever models, which are more convenient and economical to use. At this stage, it is necessary to use gaskets in order to avoid leaks in the future. All that remains is to attach the mixer to the underside of the sink using a washer, gasket and nut. You need to fasten it tightly, but do not overdo it, since if excessive force is applied, the gasket can deform, which will nullify all efforts and lead to a leak.

When the mixer is installed, it is the turn of the siphon installation: as a rule, the scheme and sequence of work is presented in detail on the packaging, so with the proper approach, even a beginner can cope with the task. However, it is worth considering a few nuances. So, it is better to once again carefully check the installation sites of all rubber seals: the presence of burrs on them can cause a leakage, therefore, in order to avoid further problems, it is better to remove them immediately. The gaskets are subjected to the same inspection procedure. Of course, pay attention to the condition of the gaskets: dry rubber, for example, will not cope with its functions, and it will still have to be replaced soon, so it is better to immediately find and use normal gaskets, and you must put them on like this, so that the cone points away from the nut.

installation of a washbasin on a cabinetNow you can proceed to the next stage, when the cabinet moves to the installation site, and the washbasin is tried on on the cabinet so that it does not interfere with the summing up of all communications. If everything fits well, and you don’t need to cut out anything, then we put the sink on the pedestal, and proceed to fixing the entire structure to the wall. To do this, you can use anchor screws, but such a fastening forces you to drill a hole in the tile, and for a washbasin with a reliable support in the form of a cabinet, it may even be superfluous. That is why it becomes more practical to use silicone, with which the sink is glued to the wall: the fastening strength is not inferior to the previous method, but after using silicone it is better not to turn on the water for an hour.

Completion – connecting water supply and sewerage. It is better to start by connecting the water supply to the faucet: this is a simple process, of course, unless you decide to connect the faucet directly to the water pipes. With the help of union nuts and rubber gaskets, a corrugated metal hose and a flexible hose are connected to the mixer. Try not to overtighten the nuts so that they do not accidentally cut out the seals, otherwise you will have to tinker. If everything went well, then you can proceed to connecting the sewage system: you need to connect the corrugated hose from the siphon and the bell of the sewer outlet, and to make this connection tight, gaskets or special cuffs are usually used.

This is where the process ends, you can turn on the water and check the quality of the work done.

It is worth noting here that instead of special, ready-made pedestals, shelves are sometimes used. In this case, the shelf itself is attached to the wall using dowels, but before installing it, it is necessary to cut a hole in it that corresponds in size to the washbasin, because it will then be inserted into it. If the washbasin will be invoiced, then it is necessary to provide an opening of such a size so that all the necessary elements of communications can be easily located there. After the shelf is attached to the wall, a sink is inserted into the hole, fixed with a sealant, all communications are connected according to the method described above.

Installing the washbasin on the brackets

installation of the washbasin on the bracketsA wall-mounted washbasin is one of the most popular types of washbasins, especially in small bathrooms, where this technique allows you to visually increase the space. Cope with the installation of this type of sink is not difficult.

Initially, it is necessary to mark the wall: using a ruler or a hydro level, the height required from the floor is measured, and a line is drawn with a pencil – the place where the sink is installed. Now, downward from the resulting line, set aside a segment, the length of which equals the width of the side edges of the sink, and also make a mark on the wall. Now we try on the brackets to the sink, and then we attach the resulting system to the wall to check the correctness of the lines drawn.

mounting the washbasin on the brackets 2After making sure that the marking is done correctly, through the holes for fixing we mark on the wall the places where the fixing will need to be done. Now we drill holes at the designated points, insert plugs or dowels there and fix the brackets with self-tapping screws. Now it remains to install the sink, connect the siphon and install the mixer. As a result, the washbasin should not wobble, and it is better to seal the gap between it and the wall with a sealant so that water does not get there.

Installing the sink on a pedestal

installation of the washbasin on a pedestalPedestal shells are commonly referred to as “tulips” for their similar shape. They are made of faience or porcelain, less often – their glass or artificial stone. If you want to install such a product in your bathroom, then you will need strong walls, since such a sink rests on them and on the floor. That is why you should not install such a product near a drywall wall – it may not withstand the load. Special requirements are also put forward for the floor: it must be as flat as possible so that the sink does not warp on the pedestal. If there is a slight bias, then it can be corrected with silicone gaskets, and if the angle of inclination is very large, then you cannot do without cement alignment. To check how stable the structure will turn out, it is pre-assembled. At this moment, by the way, it would be nice to mark the location of each of the parts on the floor and wall. When marking, it is better to use a level to be sure that the structure will definitely be level.

installation of the washbasin on a pedestal 3Now we start drilling the holes, which we then grease with glue and hammer in the expansion dowels there. We install self-tapping screws into the prepared holes and put the shells on them. Now we install the pedestal, which must be mounted so that the drain hole is located exactly in its center. Then we put on the gaskets on the self-tapping screws and carefully screw them to the wall, not tightening the nuts too much, so as not to damage the entire structure.

The installation of the mixer and siphon is carried out according to the above schemes. By the way, it will not be superfluous to use an overflow hole in the sink, which is also discharged into the sewer.

In conclusion

It is worth starting self-installation of the sink only if you are confident in your abilities and have at least minimal experience in such matters. Otherwise, problems may arise either with the installation or with further functioning in the form of unforeseen emergency situations.

But many craftsmen are able to cope with such a task on their own, especially since the whole process is not so complicated. Whether it is the installation of adjustable sinks, when using pedestal poles with a screw system to adjust the height, or screw mechanisms attached to the walls. Sinks are even sometimes hung on ropes or chains from the ceiling: it becomes easy to adjust the height, the decorative function is expressed as much as possible, but installation will require a professional approach.
