At what height is the outlet of the sewer under the sink. Bathroom sink installation height: standards and wiring diagrams. Video tutorial: installation and connection of the sink on a pedestal
The sink in the bathroom or in the kitchen is a household appliance that is closely related to everyday life people living in an apartment, house, country house. It would seem that there is nothing easier than installing a sink and using it comfortably.
Note, as practice shows, even the height of the sink in the bathroom has an impact on the degree of convenience for the user, not to mention other subtleties of installation.
We will tell you how the optimal sink height is determined, taking into account design features appliances and ease of use. Here you will learn how to pick up and install a siphon for a suspended sink. With our advice plumbing work will be carried out perfectly.
If we turn to the standards for installing plumbing fixtures, in particular, bathroom sinks, they are directly related to the physiological parameters of a person. Specific physiological parameters, in turn, are determined by the age (and gender) of people.
There is no single clearly defined figure that determines the height of the installation of sinks for bathrooms or kitchens.
- older age, average height (800 mm);
- young age, average height (700 mm);
- children's age, average height (600 mm).
As a rule, construction organizations involved in social facilities adhere to these installation parameters. Kindergartens, clinics, schools, etc. - at such facilities, installation is carried out strictly according to the standard.
Installation of the sink in full accordance with the parameters standard requirements gives the owner of the bathroom additional amenities and comfort. An incorrectly calculated installation height alone threatens to cause wet floors
Owners of personal households (apartments, houses, summer cottages) often turn a blind eye to the standard of installation height for sinks in a bathtub. Here, installation is usually carried out based on personal preferences and ideas about comfort. And yet, it is recommended to take the distance as the golden mean of height: the floor is the edge of the sink, in the range of 750-850 mm.

About installation schemes for household sinks
modern industrial production release sanitary sinks the most varied configuration. At the same time, the variety of appliances for bathrooms and kitchens affects not only the design component. Schemes for installing sinks in bathrooms and kitchens may also differ.
The indicated values are relevant for medium-sized plumbing fixtures. Installation of larger models will require adjustments. In any case, the documentation for the new device contains installation criteria for all .
The installation of the bowl and the connection of communications are completed. The master only needs to put a pedestal under the sink, after which the system will be ready for operation. The pedestal hides the details technical connections, which is no less important
Usually fasteners and mounting fittings are included in the instrument kit. If not available, they can be purchased separately. The standard mounting hardware kit contains a pair of gaskets and the same number of screws with dowels.
It should be noted that there are models of sinks for sale in the bathtub with decorative pedestals. Such a scheme excludes the functions of the pedestal as a supporting component. It simply closes the connection points to communications.
Installation of plumbing with a decorative pedestal is carried out as follows:
- A sink is attached to the marked wall surface.
- Faucet mixer installed.
- The device is connected to the cold water / hot water lines with flexible hoses.
- The siphon system is installed.
- The pedestal is installed according to the previously marked landmarks.
Fixing the sink to the wall is not a difficult process. But here it is important not to overtighten the fasteners. Faience or porcelain is a fragile material. The standard one is fixed with two screws.
On the back of the device there are special holes for this. The softness of the suspension (cushioning towards the wall) is provided by silicone gaskets.
Schematic solutions in the style of "moydodyr"
Complex wiring diagrams with markings and fitting do not threaten the “moidodyr” of the floor type. This is one of those bathroom plumbing options that is actually done on a turnkey basis. That is why the floor systems "moidodyr" have won consumer sympathy.
The basics of installation here come down to assembly and then laying the sink on the countertop. The installation height of the sink, in this case, depends on the height of the cabinet. But, what is remarkable, furniture, as a rule, has support legs equipped with a height adjustment mechanism.
The convenience of the devices of the outdoor "moidodyr" series is an obvious fact. In this installation option, there is no need to fix the sink to the wall. However, there are devices of the same type that are mounted according to the wall suspension scheme.
Meanwhile, there are also constructions "moidodyr" hanging type. Moreover, there are two types of such products - for installation in the area of \u200b\u200bthe corner of the room with a bathroom and for installation on a flat wall. Such a project will have to be installed according to the scheme of a full-fledged installation - with marking, drilling, and the creation of fasteners.
True, with any installation of the “moidodyr”, the standard sizes remain relevant:
- distance from the floor to the outlet point of the sewerage system (510 - 590 mm);
- distance from the floor line to the cold water and hot water outlet points (560 - 650 mm);
- distance between cold water and hot water outlet points (80 - 150 mm).
As can be seen from the indicated standard parameters, there is sufficient headroom when manipulating the installation. Nevertheless, each sink of a particular “moidodyr” model is often distinguished by individual circuit solutions. Projects contain several components, and the sink is just one of them. Moreover, there are models of sinks with or without a place for a mixer tap.
Installation and connection of the mixer tap is carried out in the traditional way:
- put a gasket on the threaded limit switch;
- insert the mixer tap into the hole in the sink;
- put a second gasket on the trailer from below;
- screw on and tighten the lock nut;
- connect flexible hoses to the cold water / hot water lines.
By standard scheme the siphon outlet is also connected to the sewer line. Typically, a corrugated tube with a diameter of 40-50 mm is used for these purposes.
Rational installation of water lily shells
The installation scheme with rational use space under the sink. It is obvious that this space can be usefully used to accommodate some household equipment relating to the bathroom.
For example, place a compact washing machine there. It is only necessary to choose the plumbing of a suitable configuration.
Such sinks include models of the "water lily" series and similar ones. Design feature - the drain pipe is located as close as possible to the rear wall of the device (in the center, left or right). The shape of the bowl is flattened (height 130-160 mm)
If placement is foreseen exactly, it is recommended to choose models where it is applied horizontal scheme drain pipe.
Judging by the operation, the horizontal drain scheme does not seem to be entirely successful. This arrangement is fraught with frequent congestion formations.
Both from the point of view of design and in terms of comfortable operation, the installation scheme for the installation of water lily shells requires a clear combination of two objects according to overall dimensions. That is, in width and length from rear wall to the end of the sink and washing machine should be almost flush.
Even more convenient option installation, a project is considered where the length of the water lily shell extends 50-60 mm beyond the line of the front panel of the washing unit.
Installation scheme with rational use free space bathroom premises. This option is especially relevant for small rooms, where every square meter is in short supply
Installation of a plumbing fixture must be carried out on special mounting brackets. There is always a small gap between the top cover of the machine and the bottom of the sink, allowing you to move the machine freely if necessary.
The optimal height size for the washing unit is 650-700 mm. With such parameters, it will not be difficult to install the sink within the height standards of 800-850 mm.
Siphons for water lilies are slightly different in size (they are smaller), but the installation scheme is not much different from the usual version.
Countertop washbasin as a single project
To place a washing machine in tandem with a sink, schemes began to be offered not so long ago complete solution. Construction of two different elements constitutes a whole.
The functionality and convenience of such solutions are attractive, but their purpose is bathrooms. large area. If you wish, you can get a draft of an individual plan. However, the cost of such solutions is not available to everyone.
The choice of such structures is limited to two options:
- countertop as one piece with the bowl;
- countertop with mortise bowl.
This design is installed in the same way as it is done with other types of devices. For example, if you have a worktop with mortise sink, before the installation of the board is performed, then the bowl of the sink is superimposed.
The tabletop is laid on mounting metal corners. The location of these elements is pre-marked, taking into account the future location of the upper part of the countertop at around 850 mm from the floor level.
Sturdy corner brackets and wall corner supports are required to fix the elements of the sink-countertop scheme. Such projects are usually built on stone countertops, the weight of which requires reliable fasteners.
The supply of communications is carried out based on the power of the washing machine and the sink, as well as taking into account the load on the sewerage system simultaneously from two devices. The entry / exit points of communications must comply with the parameters indicated in the technical documentation for the machine and plumbing.
Standards for mounting dimensions are usually taken as follows:
- height from the floor to the top edge of the bowl (850 mm);
- height from the floor to the bottom of the siphon (700 mm);
- height from the floor to cold water / hot water and sewerage points (600 mm);
- distance between hot water/hot water points (at least 150 mm)
It is recommended to mount countertops based on natural or artificial stone. Wood and especially drywall, even if there is strong protection against moisture, in the conditions of the bathroom they will not last long.
How the installation is carried out, as well as how to choose it correctly, is described in detail in the next article.
Siphon connection diagrams
Regardless of the design of bathtub sinks and how they are installed, siphons are traditionally used:
- single-turn;
- double-turn;
- bottle.
The use of a single-double-turn siphon is typical for water lilies, when it is necessary to free up as much free space under the sink as possible to accommodate a washing machine or other household items.
The name "single-double-turn" was obtained due to the presence in the scheme of one or two pipe bends. Due to such bends inside the line, a hydraulic seal is created.
Another option - "bottle", is the most common. It differs from the first one in the absence of bends, the functions of which are performed by a special “bottle” with a drain pipe from the top of the structure. This scheme is more convenient than the first one when performing maintenance - clearing the line in case of blockage. At the bottom of the “bottle” there is a technical cap that can be easily turned off.

A few tips for installing your sink will help you get it to the right height.
Installation work on the installation of sinks inside bathrooms, carried out taking into account existing standards and schemes, is a guarantee of convenience and comfort.
Existing options, values for height, width, length, etc. calculated on the basis of operating practice. You can deviate from these parameters and values to some extent, but it is not recommended to ignore them completely.

The modern construction market is saturated huge amount various types faucets, sinks, sinks, bathtubs and toilets, differing in size, color and design. However, despite the apparent diversity, plumbing fixtures can be clearly divided by functionality and method of connection with pipelines. pages of the site, we will not touch on the topic of choosing sanitary equipment of a particular company and their design differences, but we will focus only on the most common ways to connect them to pipelines.
Plumbing fixtures should be installed after the installation of pipelines and the complete readiness of all construction and preparatory and finishing works, i.e. before finishing premises. Before installing the devices, plumbing connections must be made ending with water sockets with internal thread 1/2 inch or elbows, tees, couplings or manifolds with the same thread for connecting mixers or other types of taps to them. The distance between the axes of cold and hot water outlets for wall-mounted mixers should be strictly 15 cm. under washing and dishwashers can be 40 and 32 mm, depending on the type of unit. In this case, it is better to make the same type of bends with a diameter of 40 or 50 mm, since today you have one washing machine, tomorrow there may be another, and manufacturers washing machines supply drain hoses of their products with adapters for these drain diameters.
All plumbing fixtures are installed strictly according to the level. The height of their installation is regulated normative documents. Permissible deviation in dimensions for all free-standing devices 20 mm.

It is advisable to install sewer outlets and water supply lines (apartment pipelines) in the presence of already purchased plumbing equipment: sinks, sinks, faucets, siphons, etc. This is especially true for closed pipelines hidden in a wall or floor structure. If an open pipeline can be “corrected” when installing equipment, then with a closed one it will be extremely problematic. With today's development of chemistry, in particular, means for cleaning sewer pipelines, as well as with technological methods for connecting pipes and fittings, a modern pipeline looks like shown in Figure 35. That is, only water sockets and a socket are visible from a wall or floor sewer pipe, the rest of the pipeline is hidden in the wall or behind a false wall. With this installation of pipelines, bulky plumbing equipment: toilets, bathtubs and showers, as well as all kinds of furniture, can be moved close to the walls.
Rice. 35. Socket for connecting plumbing fixtures
However, hidden installation also implies a more accurate location of water outlets and sewer outlets. For example, installing a washbasin in a bathroom with wall mount the mixer assumes the presence of the sink itself and the siphon to it. The outlet from the siphon immediately enters the wall, which means that at least you need to know the depth of the sink and the height of the siphon in order to mark the exit point of the sewer pipe from the wall. According to the norms, the faucet should be 200 mm higher than the edge of the sink, here water outlets should come out of the wall. If you can decide on the installation of a sink and a mixer without buying a sink according to the above table, then it is quite difficult to do this with the outlet of the sewer pipe: sinks are made of different depths, and siphons various heights. And another case, suppose that instead of wall-mounted, you want to install a faucet on the sink that is attached directly to the sink shelf. The situation is changing dramatically. Connecting the faucet to water outlets located above the sink will be extremely unaesthetic. Water sockets in this case should be below the sink (Fig. 36). Moreover, at such a height that it does not interfere with the connection of the mixer to them rear shelf sinks and that there is enough length of the eyeliner supplied with the faucet. Well, if these are flexible hoses, they can be thrown out and longer ones put in, but what if they are brass or chrome-plated pipes supplied with the mixer? Of course, it is possible to extend the branded connection of an expensive imported mixer with flexible hoses, and it will work. long years, but this is somehow wrong, it’s the same as attaching a bumper from Zaporozhets to a Mercedes: they’ll go, but they will laugh.
Rice. 36. Example of sink connection Thus, at high quality work and hidden laying of pipelines, it is necessary to accurately mark the outlets of water outlets and sewer outlets for existing plumbing equipment. For washing machines the recommended water outlet is located at a height of 80 cm (although options are possible here), the water connection is not regulated, but is done at approximately the same height.
If lower requirements are imposed on the quality of work, then the outlets for water outlets for mixers installed on the appliance shelf, and sewer outlets can be made lower, for example, 30–50 cm from the floor, and the water supply and drainage can be made with flexible hoses and a corrugated sewer pipe. To install wall faucets, you should be guided by the standards given in the table above and on the website page. Drainage from showers, bathtubs and toilets is done directly at the floor, the water supply depends on the type of mixers: wall-mounted or floor-mounted (in the sense, on the appliance shelf) and is made either above or below the installation site of the device. And of course, the pipelines should have slopes towards the riser: in the sewer for a constant flow of liquid, in the plumbing (cold and hot water) to empty the system during repairs. Water pipes must be without fail directly at the riser are equipped with shut-off ball valves and preferably water drains and dirt traps: imported plumbing does not tolerate dirty water with particles of sand, rust and other impurities.
Sanitary fixtures are attached to stone or concrete walls and partitions, as a rule, with the help of dowels and self-tapping screws, and to wooden structures- directly with self-tapping screws.
There are a lot of questions that come up during the renovation process. I will single out the most common ones that arise during the repair of bathrooms.
What is the slope of the sewer pipe?
- for a pipe with a diameter of 100 mm - at least 2 cm / meter
- for a pipe with a diameter of 50 mm - at least 3 cm / meter
At what height is the sewer...
- for an attached toilet bowl 160-190 mm (depending on the manufacturer and model), fitting in place will give the most correct answer
– for a wall-mounted toilet 220-240 mm from the floor
– for a shower cabin with a 60 mm tray
– for washbasin 500-550 mm
– for a bathtub 100-150 mm
– for kitchen sink 300-400 mm
- for washing and dishwasher 500-650 mm
If, for technical reasons, the sewer outlets for the bathroom (shower, toilet) are made higher, then a podium can be made under the bath (shower, toilet) to the required height. Perhaps this situation will upset someone, but on the other hand, this podium can play a decorative character.
An example of a podium for a shower cabin.
At what height is the cold and hot water…
- for an attached toilet bowl 400-600 mm (depending on the water supply to the tank - bottom, side or back) fitting in place will give the most correct answer
- for a shower cabin with a tray 1200 mm from the bottom of the tray, and shower heads - 2100-2250 mm (from the bottom of the watering can to the bottom of the tray)
– for a bath 750-800 mm from the floor
– for washbasin 550-650 mm
– for kitchen sink 500-600 mm
– for washing machine and dishwasher 500-750 mm
Distance between water outlets…
– for shower and bath 150 mm from the central axes
– for a washbasin and for a kitchen sink 100 mm (not so rigidly tied, as they are connected by flexible hoses)
The bath is mounted at a height of 600 mm, the washbasin 850-900 mm.
These sizes are subject to change and depend on the height of family members. And behind them they pull the adjustment of the remaining dimensions (output of water outlets)
And do not forget that the floor level in the toilets and bathrooms should be 15-20 mm lower than the floor level in adjacent rooms, or the rooms should be separated by a threshold. And also do not forget about waterproofing in the bathroom and toilet.
It is advisable to buy all the plumbing before the plumbing begins. communications. This will simplify the task of the plumber and reduce the risk of errors.
