Office under the stairs. Design of the space under the stairs: stylish and functional solutions (95 photos). Kitchen under the stairs: design features

If more than one person lives in the house, an additional bathroom will definitely not be superfluous. And if there are often guests there, even more so. And sometimes you have to look for a place for the only “corner of thoughtfulness” in the house if the opportunity to create it arose much later than the completion of construction. But you can always find a way out - for example, placing a toilet under the stairs in the house.

The space under it is often not used in any way, or is used for storing rarely needed items - seasonal clothes and shoes, a vacuum cleaner, etc. So why not make this area functional and useful, and at the same time beautiful?

It doesn’t matter what style the room with the stairs is decorated in. The partitions that hide the restroom underneath can be finished to suit any style - from rustic to the most modern. This is not the most important difficult task. Difficulties may arise in a completely different way.

Requirements for toilet design

Unfortunately, to implement this idea, you need not only funds and desire, but also compliance with certain conditions that take into account the specifics of the bathroom, and the materials from which the staircase and the house itself are made.

Among them:

Technical feasibility of connecting water supply and sewerage systems to the selected location;
Required device forced ventilation;
The need for waterproofing.

But that's not all. A bathroom underneath can only be placed in a niche with sufficient dimensions.

The minimum dimensions are 0.8 x 1.2 meters, provided that only the toilet is installed. If a sink, bathtub or washing machine is planned, they are increased accordingly.

For reference. If the size of your niche is a little smaller, it doesn’t matter. In city apartments under toilet room Often a very tiny room is also allocated. Modern plumbing fixtures that take up little space will help you get out of this situation. But more on that later.

Where the toilet is installed, the ceiling height must be at least one meter;
And his height in front of him is at least a few centimeters greater than the height of the tallest member of the family. Of course, if we are not talking about a children's toilet;
The same applies to the ceiling height at the sink and other plumbing fixtures:
The door to the room must open outward.

Advice. If there is no room for a swing door to the bathroom, you can consider sliding or folding structures. But keep in mind that they do not provide high-quality sound insulation and odor protection.

Communications

The easiest way is to install a water supply under the stairs and drain the wastewater if there is a kitchen or other nearby. utility room with communications. We will not describe in detail how such work is carried out; we will only touch on the most important points.

Effluent from the toilet can be discharged directly into a septic tank or shambo using a separate pipe, or connected to a common house pipe. sewer system. In this case, it is necessary to provide an angle of inclination of the pipeline for the free passage of waste by gravity.

It depends on the diameter of the pipe. The instructions recommend using pipes of the following diameters for sewer installation in a private house:

50 mm– for indoor sewerage from bathtubs, sinks and showers. The optimal angle of inclination for them is 2.5-3.5 cm per linear meter;
100 or 110 mm– for drainage of wastewater from the toilet with a slope of 1.2-2.0 cm per linear meter;
Pipes of the same diameter or the next standard size (150 mm) used for external laying and give them a slope of 0.7-1.0 cm per linear meter.

The water supply line can be laid from the nearest node using the same pipes as the entire system in the house. If it is not available, water is supplied from a well or a well with an installation pumping station, for which you also need to find a place.

In this case, for year-round living water pipes laid below the ground freezing level, or insulated and equipped with a heating cable.

It is important! If the house is intended only for summer living, the water from the system must be drained in the winter.

Another important point: before making a toilet under the stairs, take care of the ventilation of this room. Otherwise, you risk constantly feeling unpleasant odors, and also acquire mold, which is very difficult to get rid of.

This is quite a difficult task if the stairs are located far from the external walls. You will either have to run the duct under the first floor ceiling, or route it through the second floor to the roof or attic space.

Finishing

Before finishing the toilet in the house under the stairs, you need to think about waterproofing the floor. And protecting walls from mold and rot if they are wooden. This also applies to elements.

All wooden structures are treated with special protective compounds. If you decide not to hide them under tiles or plastic panels, you can use stains, varnishes or tinting impregnations.

The choice of waterproofing depends on the material from which the floor is made and the type of finished floor covering:

Natural wooden floors are covered with several layers of varnish or water-repellent impregnation;
On concrete base apply bitumen-polymer mastic, then make a screed and lay tiles or linoleum;
You can lay bitumen-based roll insulation under the laminate.

The toilet and bath under the stairs in a country house are finished with standard moisture-resistant materials: tiles, plastic panels, moisture-resistant paint, etc. Below are some examples.

Advice. For the installation of partitions, it is best to use moisture-resistant plasterboard. It can be painted over putty and tiles can be glued to it.

It is important to think carefully about lighting. If the ceiling height is small, pendant and built-in lamps are unlikely to be relevant. Flat ones to the rescue ceiling lamps and wall sconces.

Equipment and furnishings

As a rule, the bathroom under the stairs has very modest dimensions, limited by the width of the span and the slope of the structure. And in this limited space you can't go wrong, so you have to select the plumbing fixtures very carefully.

Pay attention to the following items that differ in functionality and optimal dimensions:

Wall-hung toilet with installation. It does not have a visible tank - it hides in a niche in the wall or in a box specially built for it. In our case, if the toilet is placed at the end of a niche, there will be a place for installation under the lower steps of the stairs, which is still not used.

Mini-sink. If you only need it to rinse your hands, there is no need to buy a large product. Compact sinks are wall-mounted and corner, built-in and wall-mounted, deep and flat. There are even some that can be installed on washing machine, which greatly saves space in a small bathroom.

Hygienic shower will successfully replace a bidet and allow you to easily fill a bucket with water for wet cleaning.

As for furniture, such a small room is unlikely to fit full-fledged cabinets or cabinets for linen, household tools and household chemicals. But you can find or make to order narrow cabinets or hanging cabinets.

In any case, you can always find a place for small shelves for hygiene items. And if you have built an installation box, you can put it to good use horizontal surface, and a cavity in which it is easy to hide pipes and water supply.

What else can you do under the stairs?

If you live in a city two-level apartment, where “wet” areas cannot be placed above dry ones.

Or you don’t have the desire or ability to run communications through the entire house.
Or the niche is too small to fit a toilet.
Or you just don’t need another bathroom under the stairs - what else can be installed there?

Many things. For example, a small niche adjacent to the bathroom or kitchen can accommodate a washing machine, dishwasher or dryer. You just need to put hoses there to supply and drain water. And if you want to make this design with your own hands from metal frame and drywall.

And if there is no need to lay communications, then a huge number of options arise. And the price for arranging such a space is reduced significantly.

It's easier to show examples than to describe possible solutions, so see for yourself:

It can also become a place to store bicycles and skis, a small workshop or a house for a pet.

And you need to use it not only because there is not enough space in the house for these purposes. A simply furnished niche looks much more aesthetically pleasing than empty space or a warehouse of unnecessary things.

Conclusion

In the video in this article you will find many other examples of the use of under-staircase niches. And if you want to thoroughly understand how to make a toilet under the stairs, then you will have to become a little plumber and a little builder. We wish you success in this.

When there is not enough free space in the house, when every meter counts, you have to rationally approach the issue of its use. The space under the stairs is no exception. However, many owners country houses They don’t attach any importance to this area, cover up the space and don’t use it in any way.

But it’s in vain: you can show your imagination, devote some free time and use Construction Materials, and ultimately get a rational use of the precious meter. The space under the stairs can be designed in accordance with the design of the house.

Functional room under the stairs: kitchen arrangement

It is rare to find a kitchen located under flight of stairs, however, this option also occurs if the house is decorated in the “loft” style. A kitchen under the stairs involves placing its individual components in a niche: a sink, wall drawers and shelves. Sometimes gas equipment is placed in a niche. Buying kitchen furniture for the stairs is an impossible task, so in this case it will be necessary to order individual project or make it yourself.

The kitchen under the stairs has some features that are associated with the slope of the structure. Will this be an obstacle to comfortable use of the kitchen? You should think in advance about how communications will be laid into the space under the stairs.

It is also necessary to take into account that steam will come from the sink, and this will adversely affect the condition wooden structure. Therefore, it is necessary to ensure good insulation and also consider a ventilation system.

You can install another one in a niche household appliances: refrigerator, dishwasher, shelf with microwave, and washing machine.

If necessary, also provide additional lighting. Don't forget about the hood. We will have to extend a ventilation duct into our area. If this is not possible, you can use a hood without an air duct.
Risers. It is necessary that they be present in the staircase structure. Open marches will promote settlement on kitchen surfaces dust flying from above.
Protection of the staircase structure. When using kitchen equipment, the stairs will be exposed to unfavorable factors, such as high humidity, temperature changes. This must be taken into account when choosing material for the stairs and methods of finishing and processing. It is also desirable that the design is easy to clean.

Cabinet. It is also possible to place a small library here.

Wardrobe.

Bathroom. If space allows, you can additionally install a sink and bathtub.

Installation of a bathroom under the stairs

Construction of a toilet in the space under the stairs requires the presence of certain knowledge and skills.

This is a rather critical area, and the following aspects should be taken into account when designing:

Carefully calculate whether the size of the niche allows you to place a bathroom underneath it.
Possibility of connecting sewerage and water supply, installation of ventilation.
When placing a toilet, be sure to treat the inside walls with antibacterial agents and waterproof the floor.
Seasonal deformations are possible in a wooden house. This must be taken into account when laying communications (special damping devices are installed or gaps are provided), as well as when choosing materials for finishing.

The placement of a bathroom in residential buildings is regulated building codes(SNiP). Despite the fact that strict rules do not apply to private houses, and it is permissible to arrange a toilet under the stairs in a wooden house in accordance with the existing conditions, based on ease of use, you should have an idea about these requirements.

The minimum toilet size is 0.8x1.2 m; With installed sink- 1.6x2.2 m; combined with a bathroom - 2.2x2.2 m. Ceiling height - 2.5 m. There must be at least 0.6 m of free space in front of the toilet. The entrance to the bathroom is prohibited from the living room or kitchen. The door must only open outwards.

Let's take a step-by-step look at how to arrange a bathroom in a wooden house under the stairs with your own hands.

Installation of water supply and sewerage

To supply water to the bathroom and remove waste water, it is recommended to use pipes made of plastic and metal-plastic to eliminate possible deformations. Most often, PVC pipes with fittings are used for sewer installation.

Special rubber sealing rings are installed at their connection points. Pipes must be insulated using mineral wool or expanded polystyrene.

Sewage installation

An important task when carrying out sewer installations is to ensure the free passage of wastewater, without delays or congestion.

To do this, it is necessary to provide for the angle of inclination of the pipes. It depends on the diameter of the pipes, and should ensure a fluid flow speed of 0.7-1 m/s (calculated optimal speed sewer water).

The angle of inclination is determined in centimeters per 1 meter of pipe. The most convenient way is to set it using a level.

Requirements for sewerage are established in SP 30.13330.2012 “Updated edition of SNiP 2.04.01-85 “Internal water supply and sewerage of buildings”” and SNiP 2.04.03-85 “Sewerage. External networks and structures."

Typically, pipes with a diameter of 50 mm are used inside the house, and for external installation - 100-150 mm. For withdrawal Wastewater A septic tank with a filter system is installed in which the wastewater is purified in such a way that disinfected water can be safely discharged into the ground.

If it is not possible to install a competent septic tank, you can take a simpler route - dig a couple of pipes into the ground to collect sewage water. concrete rings, but then there may be a problem with a fetid, pungent odor.

This scourge can be almost completely overcome by timely pumping out of the storage tank using special equipment and the use of enzyme preparations.

Used for pumping sewage water fecal pumps. They differ in power, configuration (can be equipped with automatic equipment, a shredder), material of manufacture (steel, plastic, cast iron) and installation options (submersible, semi-submersible, surface).

When choosing a pump, take into account:

Transportation distance.
Performance.
Inclusion size.
Chemical composition of wastewater.
Temperature regime.

Installation of water supply

If there is no centralized water supply in the premises, the water supply is carried out from a well or borehole.

Laying a water supply system consists of several stages:

Compilation detailed diagram water supply with connection points and taking into account all components: pump, boiler, filtration system, collector.

It is possible to organize water supply without using a collector, but only if the water consumption in the house is small. At this method It is enough to connect the water consumption points in series.

Here you may encounter the problem of reducing pressure pressure at the most remote points, while simultaneously using several water intake units at once. However, this connection results in significant savings on piping.

Determining the diameter and type of pipes for laying water supply.

The choice of material from which pipes are made is not an idle question.

There are several points to pay attention to:

Easy to install. Installation of pipework requires the use of special equipment and tools.
Influence of temperature factors. Metal-plastic pipes tension cannot be installed. Temperature changes can cause connections to become loose.
Durability.
Easy to maintain. Steel pipes without proper care they are susceptible to corrosion.
Price. The most expensive are copper pipes.

Have become quite popular recently polypropylene pipes(For hot water- reinforced). They have good performance characteristics, their service life can reach 50 years; such pipes do not require special care.

Having grouped all the pipes required for installation by size, their number is determined, taking into account the reserve (about 10%).
For pipeline sections less than 10 m long, pipes with a diameter of 16-20 mm are usually used.
It is important to correctly determine the diameter of the collector pipe (if a collector connection diagram is used).
To do this, the maximum water intake from all consumers is calculated. The pipe diameter is selected: 25 mm at a flow rate of 30 l/min, 32 mm at 50 l, 38 mm at 75 l.
A list of necessary filters, shut-off valves, fittings and fastenings is also compiled (it is convenient to use clips for attaching pipes to walls (see photo)).

Additionally, you should take care of the material for insulating water pipes.

System installation.

All holes for pipes in a wooden house are made with gaps to prevent destruction of the water supply system during seasonal deformations of the building.

Installation of an outdoor water supply system is carried out taking into account the depth of soil freezing. Additionally, communications are equipped with thermal insulation.
Particular attention should be paid to the section of the pipe located between the ground and the building, and located in the open air. It must be carefully insulated.
The hydraulic accumulator, metering and control devices are usually installed next to the pipe entrance to the house.

If there are no residents, in cold weather the water from the pipes must be drained, otherwise they may burst.

Ventilation installation

Ventilation in a wooden house plays an important role, since high humidity capable of causing bad smell, rot, fungus and destruction of wood structures.

The forced ventilation system must be made of non-combustible materials. The ventilation duct and air exhaust pipes are not mounted directly on a wooden structure.

There are special fastenings for this. Ventilate into the attic or under suspended ceiling. The fan must be protected from moisture.

Waterproofing device

Properly performed waterproofing will increase the service life of wooden structures.

There are two groups of waterproofing: roll and coating. Roll insulation is usually made with a bitumen base. It has a relatively short service life (no more than 15 years).
Coating materials are a water-repellent mixture that forms a protective membrane.
If the wooden floor is not intended to be finished in the future, you can apply varnish or a water-repellent coating to it.
When used for flooring ceramic tiles or porcelain stoneware, you can protect the base with bitumen-polymer mastic, since it must be covered with a layer of screed.

Waterproofing of the floor should be carried out with approaches to the surface of the walls (about 20 cm). The walls and ceiling must be treated with antiseptics before finishing.

Plumbing installation

Requirements for sanitary equipment are established by GOST 30493-96 “Sanitary ceramic products”. The choice of products is carried out based on the size of the resulting room, the tastes of the owner and his financial capabilities.

Choosing a toilet

The toilet model is selected according to several parameters:

Based on how the exit is carried out sewer pipe(from the wall or from the floor). They come with vertical, horizontal and inclined drainage.

According to the design of the bowl. There are disc-shaped, visor-shaped and funnel-shaped models. The shape of the bowl should ensure hygiene, high-quality flushing and no splashing.
In the direction of flushing. Toilets are available with direct and circular flush. The circular flush covers a larger area and produces less noise.
According to the method of fastening. Depending on the installation method, they are divided into floor-mounted and suspended. Floor-standing toilets also include corner and wall-mounted toilets, which allow for economical use of bathroom space.

According to the design and fastening of the tank. Toilets are:

with the tank located under the ceiling:
monoblocks;
with a hidden tank location;
without tank;
standard, combined with tanks.

Toilet lids can be made of polypropylene and duroplast. The first option is budget-friendly, but not durable enough. The second one has excellent performance, but is quite expensive.

TO additional advantages Duroplast lids can be attributed to the presence of a microlift, which allows the lid to lower slowly and quietly.
An important point when choosing a toilet is high-quality fittings.
Each flush uses about 6 liters of water.
Some models have a button with an economical supply of liquid.

The best option for placing a toilet in the space under the stairs would be to install it at the end of the room with a lower ceiling height.

Sink selection

There are a lot of options for sinks for installation in the bathroom. They differ in shape, material, color.

Depending on the method of fastening the sink, there are:

Finishing work
