Project of a country toilet with a shower: choice of the scheme + construction

A cottage and a shower are needed at the dacha, because only thanks to these facilities it is possible to spend time with relative comfort on your own plot. Do you agree? And they should be built before the start of garden work.

If there are no centralized water supply and sewage systems (and usually it happens), you need to think about the project of a country toilet with a shower with a separate cesspool. The best option - combined buildings with a partition under the same roof. We will tell you how to be a joint project of the toilet and shower, and what is required for its implementation.

The article presents useful recommendations from experienced professionals on how to properly design and build a joint construction with their own hands. The material is accompanied by thematic videos that will help put into practice the drafted project, as well as enrich with new ideas.

Features of the combined design

Combined shower and toilet are one building under a common roof. The premises are separated only by a wall, and the entrance to each of them is separate. Above the shower is placed above the tank. It is installed on the roof and supply water through the pipes, install a tap and a watering can.

If a washbasin is provided in the toilet, then water should come from the common tank. Similarly, water is supplied to the toilet if they decide to install a standard toilet with a sink.

However, at the dacha rarely put such plumbing fixtures, much more often they manage with a standard “hole in the floor” with a cesspool.

If a cesspool is used to accumulate waste from the toilet and shower, it should be located no less than 20-25 meters from the source of drinking water. In areas where it is not possible to comply with the rules, it is necessary to carefully concrete the bottom of the pit.

This is to avoid accidental contamination of drinking water with fecal bacteria.

A toilet with a shower is built at a distance of 10 m from residential buildings (both its own and neighbors). Violation of sanitary norms in this case threatens with flooding of foundations and basements if the pit is crowded during spring floods and / or depressurized. The distance to the fence should be at least 1-3 m.

When planning the location of the toilet with a cesspool should take into account the distance not only to buildings, but also to communications:

• asbestos cement pipes - 5 m or more;
• to cast iron pipes with a diameter of less than 20 cm - 1.5 m;
• to cast iron pipes over 20 cm - 3 m;
• to gas - 5 m and more.

It happens that the site is too small or its location does not allow to maintain even the minimum distance between objects recommended by the SNiP. In this case, you should consult the BTI, how to resolve this issue.

Building a toilet and a shower under one roof has several significant advantages:

• Compactness. Cottage is a place not only for recreation, but also for growing vegetables, fruits, berries. Each square meter should be used with maximum efficiency. Construction of the combined construction solves the problem of lack of space.
• Saving building materials. Any construction - it costs, and the lower they are, the better. Especially expensive is the foundation. If it is one for two rooms, it is already a cost reduction. If you add more savings on roofing materials and load-bearing walls, the benefit is obvious.
• Time saving. The construction of two structures takes much longer than the construction of one. You get two vital designs for almost the same period as one, because the most energy-intensive works (digging of pits, pouring foundations) are done at once for both structures.
• One drain hole. Arrangement of the drain hole requires effort, time and money. If she is alone, this is a significant savings. An additional plus is less unpleasant odors in the area, since There is only one “aromatic” zone.

There is one serious drawback, but a big one: when bathing in the shower, the smell from the toilet may disturb, but this is a solvable problem. If the ventilation pipe is brought out above the roof of the building, unpleasant odors can be avoided altogether.

Below there is a video that describes in detail the design of the ventilation of the odorless toilet.

Before building a summer shower, you should carefully consider how water will be drawn into the tank. Ideal - pump and hose.

If it is not possible to pump water from the source to the tank, it will have to be carried by buckets manually and lifted onto the roof of the building, and this is quite difficult. To facilitate the work, you need to plan a wide comfortable track.

What to consider when developing a project?

As for any other facility, for a combined toilet with a summer shower, first of all, a project is prepared.

When developing it, one should take into account such nuances:

• The layout should be comfortable.. Separate entrances are provided for each room, so care must be taken to ensure that access to both doors is free. A toilet and a summer shower should be comfortable to use. If there are children, elderly people or disabled people in the family, their needs should be taken into account.
• The project takes into account the features of building materials, finishing. The loads on future structures depend on this and, accordingly, the choice of the type of foundation.
• The area and height of the premises are calculated based on the personal needs of family members.. Most often they build structures of 2.75x2 m or 3x3 m. The height can be 2 or 2.5 m, depending on the height of family members. Too low rooms are uncomfortable, and in too high rooms it can be difficult to reach the shower head.

The calculation of the area also depends on the number of sanitary appliances and furniture. If you build spacious rooms 1,3x2 m, then there is enough space for a shower stall, benches, shelves and a washbasin. In addition, the rectangular shape facilitates the task of placing furniture and plumbing.

The more thoroughly the project is developed, the more comfortable and durable the construction will be. You should not begin construction earlier than every detail will be thought out, because building and rebuilding is much more difficult and expensive than providing all the necessary amenities once.

Step # 1 - the choice of materials for construction

The choice is small: it usually comes down to just two materials - wood and brick. For long-term construction, which will be used for decades, it is better to choose a brick. It is durable, tolerates the effects of negative external factors.

The disadvantage is that you have to build a solid foundation. This involves considerable expenses.

Wooden construction is cheaper, it can be built faster, but it is not the most durable option. On the other hand, it is difficult to build capital structures on loose soils, and for them it is better to choose lighter wooden structures. If desired, they can be trimmed outside, so that the tree is less spoiled.

Sometimes built metal toilets combined with a summer shower. This is a difficult task, because need a welding machine.

The building itself may not meet the expectations and quickly collapse due to corrosion, because in the shower there is constantly increased humidity. Another option is slate, but it is fragile, and the walls of it are short-lived.

Step # 2 - Cesspool Construction

There are two main types of cesspools - with filter bottom and sealed. The first ones are simpler in construction and do not require special expenses for operation, and for cleaning of sealed pits it is necessary to call the vacuum trucks.

There is a caveat: although many gardeners build filter pits, it is prohibited by sanitary standards, because can cause pollution of aquifers.

For the construction of a cesspool choose a variety of materials and structures:

• brick;
• reinforced concrete rings;
• solid concrete;
• plastic containers or metal tanks;
• improvised materials.

Capital leakproof pit is the easiest way to build a brick. To do this, dig a square pit of the desired diameter, compact the soil, equip a sand pillow and fill the bottom of the pit with concrete.

When the material hardens, they build brick walls (the construction should rise 10-20 cm above the ground), plaster and waterproof the bitumen mastic. Detailed instruction on the construction of a brick drain hole we brought here.

Often also build leaky brick pits. In this case, make the filter bottom, and put a brick in a checkerboard pattern, leaving gaps. Such structures do not waterproof, because the water goes into the ground, and only the sludge remains in the pit itself, which needs to be occasionally removed.

It is best to build a hermetic pit from solid concrete or reinforced concrete well rings. For waterproofing septic of rings use penetrating compounds or bitumen, bitumen-polymer mastics.

Combinations of different types of materials are possible to create a durable and reliable waterproofing layer.

Volumetric barrels with a bottom (for hermetic) or without it (for filtering) are installed as cesspools. To get acquainted with the scheme, calculations and rules of arrangement of the pit from the barrel, go by this link.

It is also possible to construct a structure from scrap materials, for example, from old used tires. There are plenty of options, especially if the drain from the shower is equipped separately.

Arrangement of a toilet without a cesspool

Sometimes it is not possible to build a cesspool due to the close occurrence of the aquifer. Then you can remove the drain pipe from the shower to the compost pile and put a bio-toilet or powder-closet. Dry closets are sold in finished form. They are suitable for installation both on the street and in the premises.

Powder-closet is a structure with a small sealed pit in which sewage is sprinkled with peat. The pit is regularly cleaned, bringing its contents to compost. If you do not live in the country during the entire summer season, this is a good option.

To make it more convenient to use powder-closet, a toilet seat with a lid is made, and a container with waste is covered with a covering. It is best to provide a special door for removing the tank. Ventilation is required.

Relatively recently, an interesting modern type of powder-closet - peat toilet. The principle of its operation is the same, but the tank with peat is located directly inside the structure. When it is filled, it is removed and cleaned. After that, the toilet is again ready for use.

We recommend to read our article on the specifics and toilet cleaning methods peat and liquid type.

Let us consider an example of the construction of a complex of a shower room with a toilet for the dacha, located in a frame building 3 m long and 1.5 m wide:

An example of building a utility block with a toilet without a cesspool will help to understand the intricacies of the process:

Having completed the lining of the facade and rear wall, proceed to the arrangement of the windows, the installation of the doors and the arrangement of the internal space:

Independent construction of a toilet with a shower

Consider the option of building a toilet with a summer wood shower with your own hands. The construction is relatively light, it can be installed on almost any soil. Under it will require a column base.

The roof can be equipped with a gable and covered with metal tile or other suitable material.

Before construction, you need to purchase materials:

• bars (for upper and lower trim, vertical supports, roof frame);
• edged boards (for crates, subfloor);
• OSB-sheets (for finishing floor, ceiling);
• pipes (for sewage and ventilation);
• plywood (for formwork);
• metal tile (for the roof);
• bulk materials - gravel or crushed stone, sand;
• metal corners (for mounting bars).

Timber must be dry (permissible humidity not higher than 22%). On boards and uneven bars there should be no defects: knots, cracks, signs of fungal damage.

Stage # 1 - arrangement of the sump and foundation

To begin with, the plot is laid out for the foundation and cesspool, and then proceed to earthworks. Under the pit they dig a pit with a perimeter of 1 x 1.5 m, a depth of 1.5 to 2 m. Walls are reinforced with either concrete or brickwork, and the bottom is concrete.

When the pit is ready, you can begin to build the foundation. Under it make small holes (20 cm) with a depth of 0.8 m. A sand pad (10 cm) is placed on the bottom of the holes and carefully tamped.

Formwork, fittings are installed in the finished wells, concrete pillars are poured and left for 2-3 days to solidify the material. After that, you can already remove the formwork. If it is hot outside, it makes sense to cover the concrete during the drying period so that it does not crack due to the rapid evaporation of moisture.

Stage # 2 - construction of the structure

A drain pipe is installed under the shower so that moisture does not accumulate under the structure and does not destroy its lower part. After that, you can proceed to the construction of the lower strapping.

The bars are connected with wooden elements, and fastened to the concrete with metal pins. Above the pit make a metal frame of the channel.

For the construction of walls in the corners set the frame of the bars, and in the place of the doorway put two pillars at a distance of 77 cm from each other. If everything is installed correctly, you can proceed to the arrangement of the upper trim. It is attached to the screws, metal corners and plates.

The ridge board is attached to the top trim. The rafters are made of boards with a step of 65 cm, after which they install the crate. Boards should protrude 20 cm beyond the edges of the vertical design. Later they will serve as a visor. Further wind boards fix and cover a roof with a metal tile.

The floor is made of boards with a minimum thickness of 4 cm. They are fastened with screws to the bottom trim. Immediately make the frame "steps" for future elevation and sheathe it with boards 2 cm thick.

It remains to insulate the structure with polystyrene foam and blow out the cracks with construction foam. Exterior walls and ceiling sheathed boards.

Stage # 3 - arrangement of shower and toilet

To arrange the drainage system, they dig a ditch and lay down a sewer pipe, which is connected to the drain. The floors in the shower are covered with rubble, reducing the thickness of its layer near the drain hole.

Crushed stone is poured with concrete so that, after solidification, the floor will turn out with a uniform inclination to the sink from all sides. The surface is waterproofed with bitumen mastic.

On top of the concrete floor is laid wooden with a distance between boards of 1.5-2 cm. The walls are sheathed with boards and treated with waterproofing agents, antiseptics.

After that, all surfaces are opened with two layers of yacht varnish. Similarly, wood cladding is treated.

A tank is placed on the roof of the structure, drain pipes are removed, and ventilation is installed in the toilet. It remains only to install the doors, take care of connecting the electricity for the use of the premises in the evening, install the shower head and equip the toilet seat.

Photo instruction for home craftsmen

The construction of the sewer system will require more money, time and effort, but in the operation of such a utility unit will be much more convenient:

For the device complex shower-toilet with drain hole from the shower box, you must first develop a shallow pit.

The sides of the pit are 4 m, the depth is 0.3 - 0.5 m, then:

The skeleton of the building is ready, now we proceed to the wall covering and the internal arrangement of the block:
