• What can be cooked from squid: quick and tasty

    Choosing how to build a bathhouse on your site in order to save money, they often stop at an extension of the structure to the main house. The annex bath has a number of advantages: cost-effectiveness, ease of installation, space saving on the site. The main thing during construction is to choose the right project, taking into account all the subtleties of the outbuilding. How to attach a bathhouse to the house, installation features and project selection in this article. We will acquaint the reader with some photos and videos on the issue of adding a steam room to the main house.

    To save space, a bathhouse is being built on the site.

    How to attach a bathhouse to the house: methods and methods

    Introducing an annex, not everyone understands that the design can be different. According to the features of installation to the main house, the annex to the bathhouse can be:

    1. An annex with three full-fledged walls and one common with the house.
    2. A full-fledged log house, which is located right next to the house.
    3. The bathhouse is located at a distance of 1-1.5 m from the box of the house. The structures are united by a warm heated corridor-vestibule. It is often used as a dressing room or rest room.

    The first two options can be located under a common roof with the house, the latter has a common or separate roof.

    It is necessary to choose what will be the construction of the outbuilding of the bath even at the planning stage. The choice will determine what the foundation will be.

    Choosing a foundation

    The foundation for an annex bath can be done by hand. It is poured separate or the tape is tied to the main one under the house. The first option is preferable, since the shrinkage will be more uniform.

    You should not choose a foundation that is different from the main one. Most suitable option tape lightweight. It is possible to bind to the main foundation using metal brackets, and in order to avoid the formation of hold bridges, the joints are additionally foamed and insulated with expanded polystyrene.

    For a bathhouse annex to a country house, you can use pieces of reinforced concrete piles or slabs as a foundation. Since the bathhouse attached to the country house has a minimum size.

    The transition between the bathhouse and the house, which is better?

    It is important to think about what the transition between the bathhouse and the house will be. The easiest option is to make a pass-through, when the door leads directly from the house to the dressing room or the rest room. The main advantage of the internal transition design is less heat loss.

    When passing through a separate vestibule, additional insulation... Tambour is used as additional room or dressing room. In the vestibule you can place benches, a clothes hanger.

    Features of communications

    Communications to the attached bath are carried out directly from home. Pipes and electrical wiring can be laid through a common wall or under the bath through the foundation. In the bath, the wiring is performed by any in a convenient way... You can put water into the bath separately, in the garden and summer cottage you can dig a well or make a well.

    Features of the construction of an attached bath

    During construction attached bath a series of sequential actions must be followed. Each of which has its own characteristics:

    1. It is important to draw up a project before construction. Even the smallest attached bathhouse for country house should not be based on the eye. The project of the annex should indicate the materials used, the layout inside the bath, the transition from the house to the bath.
    2. The foundation is made lightweight exactly of the same type as under the main house.
    3. Doorways are made low with a high threshold, for greater heat retention in the bath. For the same reason, it is better to lead the main door to the vestibule, and not to the street.
    4. The walls inside the bath are waterproofed with vapor-reflecting foil. The top is sheathed with any material you like, traditionally linden lining is used.
    5. The pipe is insulated and taken out on the opposite side from the wall of the house, so that when the fire is fired, smoke will not enter the house. Such an installation is also regulated in technology. fire safety during the construction of a bathhouse.

    It is important when building an attached bathhouse, even in a small summer cottage, to observe fire safety techniques.

    Fire safety rules for the annex bath

    It is necessary to protect the house from fire for this, a special spark arrestor is installed on the pipe from above. The device can be bought ready-made, or made by yourself.


    Decorating a bathhouse annex to a residential building.

    The joints of the walls are coated with bituminous mastic and foamed polyurethane foam... So the annex will be able to give it the shrinkage it needs without damaging the walls of the main house.

    In the dressing room and the vestibule, windows are made so that, if necessary, they can be urgently opened. Doors and windows should open outward of the structure.

    The pipe is insulated with asbestos outside and inside the bath with foil insulation. The material can withstand high temperatures and is not toxic.

    You should not build a bathhouse attached to the house in a place where it passes gas pipe... Leakage may result in fire.

    After the construction of the bath, it is necessary to invite fire service personnel and register the building. If all fire safety measures are observed, then you can safely use the bath.

    Sanitary-technical standards of the bathhouse annex

    Answering the question of how to attach a bathhouse to a country or residential house, it is worth mentioning sanitary and technical standards. They are no less important than fire safety engineering.

    Since the bathhouse is connected to the main house, it is necessary to keep the humidity to a minimum. Otherwise, the house will start to rot and collapse. Humidity can be prevented by calculating and installing the correct ventilation system.

    The exhaust from the steam room is taken to the rest room and the dressing room, last of all to the vestibule. So the heat will additionally heat the other rooms of the bath.

    In the summer, the bath is opened and dried so that moisture does not accumulate for a long time. In winter they are periodically heated.

    If there is a sewage system in the house, it is easier to combine a bath with a bathroom. So you can take bath procedures after the steam room and you do not need to arrange an additional septic tank.

    What material is better to choose for the extension of the bath

    For attaching a bath, a material is chosen that gives minimal shrinkage and is easily assembled with your own hands. For example, chamber-dried profiled timber or glued. It is not recommended to make the bathhouse annex made of material different from that with which the walls of the house were built. Shrinkage is different for different materials and cracks may appear at the joints of the walls. But a bathhouse is attached to the old house from different material: brick, foam blocks, lumber, frame made of OSV panels.


    You can attach a bath with any material, for example, brick.

    Outside, the facade is sheathed with any material you like: siding, lining, imitation of timber, block house. But using the same finishing material that on the facade of the house you can get a harmonious and aesthetically pleasing design. How to attach frame bath can be seen in the video:

    Subject to all the rules, the reader will not have any questions on the topic of how to attach a bathhouse to the house. And the steam room will delight the owners no worse than a free-standing structure.

    When building a new bathhouse on the site, the question arises of where to place it so that it is not only convenient, but also safe. Some people think that the best solution would be to attach it to the house, while others - that it is risky, as an accidental fire could occur. In addition, it is believed that the bathhouse attached to the house will become a source of excess moisture, which will cause fungus to appear, and the walls will rot and begin to collapse. In more detail, the option of adding a bath to the house, all its pros and cons, will be discussed below.

    Before attaching a bath to the house, you should carefully think over all the details of the project, so that later you do not have to redo the flaws. A construction plan that meets all modern requirements provides for:

    • heating;
    • water supply (hot and cold water);
    • sewerage.

    The first big advantage, given that the house itself already contains all the necessary communications, is savings. In this case, it will not be necessary to rebuild everything, which will save you from unnecessary costs. And if you place a bathhouse next to the boiler room, the costs will be halved.

    The second significant advantage will be the ability to get into the bath immediately from home, when equipping a direct passage from it. Also a good solution would be a door located next to the main entrance.

    In the bathhouse attached to the house, you can equip a washing area. This will eliminate unnecessary noise and clutter. You can place in it washing machine, clothes dryers and ironing equipment.

    The last but not the least important advantage will be the opportunity to arrange a joint terrace, which will be convenient both for relaxing after a bath, and for simple evening gatherings.

    Disadvantages and solutions

    Along with the advantages, there are a number of disadvantages of an extension to the bath house, which, if desired, can be avoided if you think over its arrangement in advance.

    The main fear among the opponents of such a project is that the bathhouse is an object of increased fire hazard... And it is not without foundation if a wood-burning boiler is installed and the pipe is not equipped with a spark arrestor.

    Modern technologies offer safer options for heating a bath and heating water:

    • electric heater;
    • steam generator (hamam);
    • infrared sauna.

    Each of them has different characteristics and you can choose the most suitable one for yourself.

    Also, in order to protect the house from fire, especially if it is made of wood, fireproof insulation should be laid on the adjacent wall.

    The second disadvantage of the location of the bathhouse close to the house, some consider the unpleasant smell of dampness and noise, which often occurs during gatherings in the recreation room.

    To prevent bath vapors and odors from entering the house, it would be best to make a separate passage to the bath. You can do it either through the boiler room or through a common vestibule.

    A good solution to protect the house from excess moisture would be to sheathe the adjacent wall with materials that repel moisture. Additional treatment of walls with special refractory compounds and antiseptics is recommended.

    Also, next to the recreation area, it is worth installing a toilet, and in the room itself - a small kitchen, with a minimum of necessary fixtures.

    Many people also fear that the house sewage system will not cope with the excess load. In fact, it is not like that and a big problem, as it is possible to equip a separate drain in the bath.

    The addition of a bathhouse to the house has a large number of advantages, as well as disadvantages that can be easily eliminated with proper planning of construction and arrangement of the premises.

    Sooner or later, every owner of a personal plot thinks about building a bathhouse. No wonder: having your own steam room is both a pleasure and a wonderful way to relax, relieve stress, and rejuvenate.

    Most often, baths are built in a separate building, usually in the corner of the site. However, this is not always possible and convenient, especially if the site small size... Firstly, if it is inhabited, there may not be a corny place on it for a new building. Secondly, according to the building codes SNiP, the distance from the bathhouse to the neighbor's fence should be at least 3 meters, to his house - 8 meters, and if both buildings are wooden - then all 15 m!

    So if you have a small plot, build on it wooden bath- a huge risk. A check can always come up and identify a building for demolition. How can you do everything right? We will tell you about this in this article.

    Is it possible to build a bathhouse combined with a house?

    A couple of decades ago, it was strictly forbidden to build a bathhouse in a residential building or adjacent to it in our country, due to fire safety rules. However, everything has changed, and thanks to new technologies and materials, it became possible to build attached baths that meet all the requirements of the PPB. So now the bathhouse can be located inside the house legally.

    What do you need to obtain a permit to build a bathhouse in a house?

    In order to attach a bathhouse to the house or place it inside it, you must obtain a building permit in the BTI of your area. To do this, you must submit the following documents there:

    • a certificate of ownership of a land plot or a long-term lease agreement with permission to carry out construction on it;
    • typical or individual project houses and baths;
    • site plan before construction and after the end of development;
    • a statement from the owner of the house or his trustee.

    The project of the bath is of primary importance, since it is there that all Construction Materials... It depends on their choice whether you get permission or not.

    What kind of bath can be built in the house?

    Most frequent question- is it possible to build a bathhouse inside the house if it is wooden? Yes it is possible. Main condition - interior walls that connect the bathhouse and the residential building must be made of non-combustible building materials

    Non-combustible material can be used both for wall construction and as a spacer between walls. Non-combustible building materials include:

    • bricks;
    • gas blocks and foam blocks;
    • expanded clay brick;
    • and concrete.

    As a spacer between wooden walls asbestos cement sheets or drywall can also be used.

    The latter option is the most optimal, since such a wall can be a wall of a house and a bath at the same time. Gypsum plasterboard refers to environmentally friendly non-combustible materials and is widely used in interior decoration premises for leveling the walls.

    Can a built-in or attached sauna be made of wood?

    Many homeowners believe that a bathhouse should have wooden walls. And they can be understood, since despite the flammability of wood, it has a lot of advantages:

    • the tree has a low thermal conductivity, so the steam room heats up quickly and cools slowly;
    • due to the high vapor permeability of wood, condensation does not accumulate on the walls and fungus does not appear;
    • wood is a very light material, as a result of which for wooden bath an overly massive foundation is not required;
    • wooden baths have the best air exchange. Even if the steam room is not used for a long time, unlike a brick one, there will be no musty smell in it.

    Answering the question posed: according to fire regulations, when building a bathhouse adjacent to a house, it is allowed that it can be wooden, provided that the internal walls are made of fire-fighting materials, both inside and in the places where heating devices are located.

    Observing all fire safety rules, you can safely build a bathhouse inside a residential building, having obtained prior permission and including it in the building project. This will save space at the summer cottage, make your rest comfortable, and allow you to bathe in it at any time of the year, without going outside.

    What type of wood is suitable for an attached bathhouse?

    In the old days, baths were built from logs. But building a log bath as an extension to a house is bad taste. Firstly, it is very difficult to create a normal look for such a building. Secondly, there may be difficulties with the selection of logs. Thirdly, you will have to wait until log cabin will shrink.

    It is much easier to use dried profiled timber for the construction of an attached bathhouse. Such beams have the same geometry and fit almost perfectly to each other. To insulate a log house, you can use flax, as in the old days.

    What size should the attached bathhouse be?

    The size of such a building can be any. It all depends on your wishes and the free area of ​​the personal plot. Even a small bathhouse can be made very comfortable if you make a competent layout in it.

    Although, if conditions allow, it is better not to save on the size. For example, a bathhouse made of 6x8 m timber (useful area of ​​48 m2) will become a great place for relaxation and gatherings, which will surely please not only your family, but also your friends. If the site allows, you can make a more spacious bath.

    Another recommendation: you can make the rest room an order of magnitude lighter if you choose a bathhouse project with a bay window. This will allow 2-4 additional windows to be installed. And on the porch of the bathhouse, you can have a pleasant time with a cup of tea on warm summer evenings.

    What should be considered when installing walls and floors in a bath?

    In the construction of a bath, how and from what the walls and especially the floor are made are of great importance. If your region is rather warm, and "Siberian frosts" are not characteristic of it, then this is done as follows:

    The logs are used to support the floor beams. For the durability of the structure, the beams must be impregnated with an antiseptic. Another option is tar for impregnation.

    Next, cut or grooved coniferous boards with a thickness of 19 to 29 mm are laid. This option is suitable if a bath is designed with a size of no more than 2 by 3 meters. For buildings of a larger size, logs should be placed on pillars of brick or concrete, on which a section of 25 by 25 cm is applied.

    The distance between the posts should be about 80 cm. It is better to take sand or concrete as a basis.

    Do not forget about the base for the stove and about preparing the drainage system for water flow. An ordinary pit is suitable if the soil in the area under the bath absorbs water well and has a lot of sand in its composition.

    The dimensions of the pit are selected individually for the size of the bath. The soil near the drainage pit is compacted and covered with fragments of brick, gravel, or the like. It is necessary to create a slight slope towards the pit and cover it with roofing felt.

    More effort will have to be spent on building a drainage system if the soil is clayey. You will need a pit made of concrete, a drain pipe and a water seal. The pit parameters are as follows: depth - 0.4 m, wall thickness - 0.1 m, size - 0.5 by 0.5 m.The diameter of the pipe is at least 5 cm.The pipe should be placed deep enough, but not less than 10 cm from the bottom.

    Boards are laid without gaps, but with the obligatory location of a hole for water drainage (directly above drainage pit). It is imperative to provide for a slope of the floor towards the drain. On request, the floors in the steam room and shower area can be laid out with a collapsible cover made of thin boards, and the dressing room - with a dense cover made of cattail.

    If the floors and walls are sheathed with plinth, then its water resistance must be taken into account. It is forbidden to open them with chemical coatings, in order to avoid intoxication at high temperatures.

    The concrete floor is laid on a crushed stone and sand base (10 cm each). Then the floor is insulated with materials at the discretion, on the insulation - another layer of concrete 5 cm thick. After hardening, the concrete floor is leveled, tiles are laid on it.

    I want to attach a bathhouse to the house - this is how many owners begin to think when, on cold winter days, they have to rake a path to the bathhouse, carry firewood there, and then, after the bath, go to the house with an armful of clothes and towels.
    Is it possible to attach a bathhouse to the house and what benefits and problems it promises - let's try to figure it out.

    Is it possible to attach a bathhouse to the house?

    You know, as the people say - of course you can't, but if you really want to, you can. All jokes, but in this matter you need to dot the i's for yourself once and for all.

    So, you can attach a bathhouse to the house. No regulation or law prohibits this. Moreover, the existing building standards regulate the construction of this kind of extensions - after all, it is about the extension in question rather than building a separate structure.

    In this case, you need to know how to attach a bathhouse to the house and what tolerances should be maintained so that such an extension is safe in terms of fire and operational plans.

    How to attach a bathhouse to the house

    There are three ways to add a bathhouse to your home. Let's take a look at all three.

    Method number 1. Using the wall at home

    This is a method when the bath is attached to the wall of the house, using the wall of the house as the fourth wall of the bath. That is, the wall of the house is one of the walls of the bath, one wall near the house and the bath is common.

    This method is the most budgetary for execution. It allows you to cut the cost of building the walls of the bath by a quarter. However, at the same time, you have additional costs for vapor barrier and counter fire protection.

    1. First, with this method, it is necessary to protect the premises of the house from steam penetrating through the wall of the house. If the wall of the house is made of vapor-proof materials - reinforced concrete, expanded clay concrete, etc., then vapor barrier can be neglected. If, light blocks or wood, then a layer of vapor barrier material should be laid.
    2. Secondly, with this method, you need to think about fire protection at home. If the house is built of wood, then the wall to which the bathhouse is attached is protected from possible fire. This is done using fireproof insulation, a layer of which is mounted on the wall from the side of the bath and then protected with a vapor barrier. High density basalt wool sheets are suitable for insulation.

    Attention! The ALL wall of the house is subject to protection, for the entire height and width, and not just the area of ​​the wall to which the bathhouse is attached!

    Method number 2. Attaching a bath to the house

    With this method, the blockhouse of the bath (or box) is, as it were, attached to the house. The main plus from this method is that you do not need to do a vapor barrier. Cons are still the same - required fire protection for .

    With this method, we have the usual passage to the bathhouse through the doors. Only the passage will turn out to be two walls wide - the wall of the house and the wall of the bath. It will be useful to make two doors in one large door frame... This will protect the house from steam penetration.

    If you make one of the doors fireproof, then this will further increase the fire protection of the house from the bath.

    Method number 3. Short transition to the bath

    This method, strictly speaking, cannot be considered an extension of the bathhouse to the house. In this case, the bathhouse is located close to the house and is connected to it by a short vestibule. The walls of the bathhouse do not touch the walls of the house. However, through the vestibule, electricity, water supply and heating pipes can be supplied to the bathhouse. You get a fully equipped sauna annex, but as if at some distance.

    In addition, in this case, you can also link the bath toilet with the general sewage system of the house. And also to equip a drain in a cheap bath and send it to common system sewerage at home.

    Which of the three ways to add a bath to the house is better to use? The most interesting from the point of view of safety is method No. 3. The most budgetary method will be No. 1. Look only so that the desire to save money on building a bath does not translate into a desire to save money on your own safety and the safety of your family.

    If the size of the site does not allow the construction of a separately located steam room with its own communications and functional area, then it is worth stopping the choice on the project of a bath-extension to the house. With the correct, rational approach to design, a comfortable complex can be obtained, profitable from an economic and practical point of view.

    As already mentioned, a steam room attached to the house will save space on the site. In addition, such a solution is beneficial from the point of view of comfort in winter period when to visit the bath you do not need to go out into the cold, but just open the door and go to another room.

    Another advantage of the attached structure is the possibility of increasing useful area already existing bath. For example, a steam room without a rest room was originally built, but over time the owners decided to make it more comfortable and connect it with a nearby residential building.

    If the location of the buildings does not allow connecting them to each other the traditional way, the use of the L-shaped bath project will help to solve the problem.

    Beginning of work

    An extension of a bathhouse to a residential building is organized in various ways:

    • The structure has one common and three separate walls with the house;
    • A full-fledged structure, erected close to the house;
    • A small distance (1-1.5 meters) is left between the bathhouse and the residential building, and the buildings are connected by a warm corridor. The latter can be used as a dressing room or a recreation room.

    Potential difficulties

    The addition of a bathhouse to the house is a completely solvable task. However, it requires special attention and responsibility. Otherwise, there is a possibility of structural failure and a decrease in its strength characteristics.

    The first thing a builder may face is the particular difficulty of organizing a tight connection of two walls. In this regard, most projects involve the installation of a small connecting insert between two structures, which should hide the contrast of the abutment.

    The second thing that you should pay close attention to is the quality of the bath foundation. Its depth must necessarily correspond to the depth of the base of the house. This is necessary in order to reduce the likelihood of detachment of the extension during shrinkage and operation.

    Third, it is necessary to organize a separate pipe and sewage system. Drainage of water into the general system is very unwise, as this will significantly increase the load.

    When creating a bath, you need to take care of its fire safety. I must say that it is precisely the likelihood of ignition that stops many developers from adding a steam room to a residential building.

    Design

    The design of the attached bath differs in certain features. This stage should be very thoughtful, since the comfort and practicality of the future structure depends on it.

    The first thing you need to decide on is the shape of the building and its location. Will the bathhouse have a common wall with the house, or will the 2 buildings be divided by a small vestibule?

    Finished projects

    If the owner's plans do not include the construction of a non-standard structure, then separate room factory production design can be installed. It does not need wood fuel, but is heated by an electric boiler.

    Self-design

    Self-drawing up a project requires a thorough study of construction technology. These norms should not be violated even in an effort to increase comfort.

    It is recommended to take into account the specific construction conditions, plan the number and size of premises, their location and the transition between buildings. The construction of the base depends on how exactly the extension will be made.

    Foundation

    The base for the bath is organized as a separate strip array or joined to the base of the house. The first option is considered more preferable, since it will ensure uniform shrinkage of the extension.

    When choosing the second option, the joining of the two foundations is carried out using iron brackets. The joint is filled with polyurethane foam and covered with mineral wool.

    Walls and roof

    It is desirable that the bathhouse and the house be built from the same material. The use of dissimilar options threatens with uneven shrinkage, and hence the formation of cracks in the joints.

    Fulfillment of this requirement may cause difficulty if the bath is attached to an old house that has already experienced shrinkage. Then you can take into work not only wood, but also foam blocks, bricks, etc.

    The roof is made shed. At the same time, its highest point should adjoin the wall of the house, going under the main roof.

    Conclusion

    To add a bathhouse to the house requires attention and the development of the correct project. At the end of the work, it is recommended to invite a specialist who can check the quality of the erected structure.
