“It would be nice to attach your bathhouse to the house” - so many people think, imagining how in winter they rake a path to it in the snow, carry firewood, and after the procedures they return to the house with a pile of towels and clothes. What conveniences and problems the installation of such an extension promises us, we will figure it out in this article. Content:

To begin with, you can attach a bathhouse to the house. This is not prohibited by law and building codes. Therefore, in our case, you just need to know the technology of work and the required tolerances that must be observed to ensure fire safety and convenient operation of the bath extension.
Ways to attach a bath to the house
The addition of a bath to the house can be done in three ways. Let's consider them.
Using one of the walls of the house to add a bath
In this case, the bathhouse and the house have one common wall. This method is the most budgetary, as it can significantly reduce the cost of building walls for a bath.
However, some problems associated with the use of this method still arise:
- The need to protect a room adjacent to a common wall from steam penetrating through the enclosing structure. For walls of a house made of vapor-tight concrete materials, such protection is not needed. A brick or wood wall of a house requires a vapor barrier.
- Fire protection of the building is required.
In a wooden house, the wall adjacent to the bath must be protected from fire. This is done with the help of special insulation, which is laid from the side of the bath on the wall, and then covered with a vapor barrier film. Dense basalt wool slabs can be used for fireproof insulation.
Bath in the form of an attachment to the house
In this case, the extension will not have a common wall with the house, but a separate one. With this method, there is no need for an additional layer of vapor barrier, but fire protection of the wooden wall of the house is required.
The passage to the bath room is carried out through a passage with a thickness of two walls. In such a large door frame, it will be useful to make two door leaves to protect the premises of the house from the penetration of steam.
Connecting the bathhouse with the house by the passage
In this case, the two walls of the bathhouse and the house are absolutely separated, but they are close to each other at a distance of 1-1.5 m. Their doorways are connected by a short vestibule, through which it is possible to bring water pipes, heating pipes and power supply cables to the bathhouse attached to the house. … The vestibule corridor is usually heated and is often used as a dressing room.
Advice: in this case, you can connect the wastewater discharge system from the bath with the general sewage system of the house.
Features of choosing a way to add a bath
Which of the three ways to use is up to you. In our opinion, method No. 1 is more economically profitable, but from the point of view of fire safety, method No. 3 will be more interesting.
Extensions made according to the first two options may have a common roof with the house. The third version of the extension assumes a common or separate roof.
It is necessary to choose the design of the bath extension before starting work. To do this, you should carefully study the projects of the attached baths and choose the right option, taking into account the nuances of work specific to your conditions. It should contain a specification of materials for the extension, the layout of the premises and the organization of the transition between buildings. The construction of the foundation depends on the type of extension.
The future sauna should not only be comfortable and enjoyable, but also completely safe for your home. It should not suffer from increased dampness, flooding, or fire.
Choosing a foundation for an attached bath
The foundation for the extension can be done independently. It is poured in as a separate array, or it is joined with the main tape under the house. Separate filling is preferable, since in its case the shrinkage of the extension will be uniform.
For such a bath, a lightweight strip foundation is quite suitable. The binding of the new foundation to the main one is carried out using brackets made of metal. The joints are processed with polyurethane foam and insulated with mineral wool.
Selection of material for the extension of the bath
It is not recommended to make a bath extension to a new house from materials other than those used in the construction of the walls of the house. The shrinkage of dissimilar materials is not the same, therefore, cracks may appear in the places of wall joints. The above does not apply to the old building. Here, different materials can be used for the extension: lumber, bricks, foam blocks, etc. Facade cladding can be made with clapboard, siding, imitation of timber and others. When used on an extension, finishes similar to the main structure can be achieved in one attractive and harmonious design.
The subtleties of building an attached bath
Before attaching a bath to the house, it is important to think about the transition between them. Walkthrough is the simplest option. In this case, the door from the house leads directly to the dressing room. The advantage of this junction design is minimal heat loss. The transitional vestibule requires additional insulation. Benches, clothes hangers are placed in the vestibule and used as a utility room or a recreation room.
When building an extension, it is necessary to take into account some of the features of sequential actions:
- The doorways in the baths are made low with high thresholds to keep warm. The same reason for bringing the main door not to the street, but to the vestibule.
- Waterproofing of walls inside the bath is done with foil film. Sheathed it from above, as a rule, with clapboard made of aspen or linden.
- The chimney is insulated and led out to the side opposite to the wall of the house. This prevents smoke from entering the house. Such an installation is regulated by fire safety techniques for the construction of bath extensions.
Fire safety for attached saunas
To protect the house from fire, a special spark arrester is installed on the chimney. You can make it yourself or buy it in a store. The outside of the pipe is insulated with an asbestos cord, and inside with foil insulation.
It is not allowed to make a bath extension in the place where the gas pipe passes in order to avoid a fire in the event of a gas leak.
After the completion of the construction, the sauna extension must be certified by the fire authorities. If safety measures are observed, the bath is ready for use.
Sanitary and technical standards for the addition of a bath
The attached bath must comply with the sanitary and technical standards. The moisture that gets from the bath into the house must be minimized. Otherwise, its destruction will follow. This issue is solved with the help of a properly designed and installed ventilation system.
For additional heating of the washroom and the rest room, the steam extractor can be brought into these rooms. To reduce the effect of moisture on the structure of the extension, the bathhouse is opened for drying in summer, and periodically heated in winter.
A good solution is a sauna extension adjacent to the kitchen of the house. In this case, there is a common oven. Such an extension will purify the air by warming up even in summer. In winter, the bathhouse will take part in heating the living room. Additionally, ventilation of the premises is carried out through the blower of the furnace.

That's all! We hope that our material and photos of the bathhouse attached to the house will help to unravel the secret of the construction of any extension. And let it please you with comfort no worse than a separate bath.
