How to make a bathhouse from a container with your own hands. Construction of a bathhouse from a sea container is an affordable and effective solution. Hydro- and vapor barrier, insulation

Construction of a full-fledged bathhouse with a reliable foundation and walls is a complex process that requires large financial, labor and time costs. Many novice developers simply cannot afford this. In this case, an alternative option is suitable - a bathhouse from a container, which you can build with your own hands quickly and cheaply.

Advantages of a container bath

For the construction of mobile baths, wooden or metal block containers are used. The weight and number of containers used determine the final weight of the finished structure - a 20-foot or 40-foot bathhouse. This type of steam room is a good option for a summer house or summer country house, as it has many advantages:

• Economical construction. For the construction of such a structure, it is possible to use cheap materials - waste containers, which can significantly reduce the main item of construction costs.
• Mobility and practicality. If necessary, the finished bath structure can be easily transported from one plot of land to another.
• Simplicity and ease of installation. The construction of a container-type bathhouse does not require special knowledge and practical skills, so you can do all the work yourself.

Important! The use of several containers allows you to create multifunctional bath complexes consisting of one or two floors.

Choosing a place to build a bathhouse

Before starting construction work, you should choose one that is 20 meters away from the highway and reservoir, 5 meters from a neighboring site, and 4 meters from a residential building.

You should first build supports from wooden blocks or brick columns. Slag and concrete blocks are also used to build the base for the bathhouse.

Technology for constructing a bathhouse from an iron container

You can make such a bath without problems and on your own, with only minimal skills. All work is carried out in several stages.

Preparatory stage

1. The building site is thoroughly cleared of vegetation and debris.
2. The perimeter is marked with the location of the functional areas of the building and the placement of the drainage system.
3. Using pegs and string, the perimeter is indicated, as well as the axis lines for each zone.
4. The top part of the soil is removed at the locations of the pegs for the columnar foundation.

Important! If a strip base is provided for the bathhouse, the soil is removed along its perimeter.

Construction of a bathhouse

1. Filling with a waterproofing sand and gravel layer 15 cm high. Careful compaction and moistening with water.
2. Installation of a columnar foundation using concrete and brick blocks, sand-cement mixture. In the case of installing a monolithic strip base - performing formwork, installing a frame of reinforcing bars and pouring a concrete mixture.
3. Waterproofing the finished base with rolled roofing felt, treating joints with bitumen mastic.
4. Installation of a wooden frame on a foundation made of 150 × 150 mm beams. Corners made of metal profiles are used as clamps.

Important! All wooden products must be treated with antiseptics and fire retardants before installation.

1. Checking the base with a building level, leveling it with special pads for the installed frame.
2. Installation of the selected container on the finished base. It is recommended to use specialized equipment and machinery for lifting.

Important! The structure is installed at an angle towards the washing and steam compartments, so that the water flows quickly and evenly into the drain hole.

Interior arrangement of a bathhouse from a container

After completion of construction and installation work, you can begin the internal arrangement of the building.

1. Electricity supply to the bathhouse, wiring to all functional rooms.
2. Thermal insulation of the building with safe and durable materials. All surfaces require insulation - walls, floors and ceilings. Surfaces are thoroughly cleaned of dirt, existing defects and irregularities are repaired. Next, waterproofing is laid, and then thermal insulation. An outlet hole is made in the steam room for the drain pipe.

Important! Basalt wool, polyurethane foam and polystyrene are used as insulation. Installation of thermal insulation is carried out on all surfaces, except those where heating equipment will be located.

1. Decorative finishing of premises. If the bathhouse is built from a sea container or a wooden cabin, siding or wooden beams pre-treated with antiseptic preparations are used for the outer cladding. For interior decoration, it is advisable to use wooden lining or ceramic tiles.
2. Selection and installation of a sauna stove. Installation of the outlet for the chimney pipe is carried out before decorative finishing of the ceiling. For a mobile sauna, it is recommended to use a wood-burning or electric heater. When installing equipment, all surfaces located nearby are provided with additional fire protection. A hot water supply system for the washing department is being installed by installing heating equipment equipped with a water tank.
3. Installation of windows and doors. To maintain optimal temperature indoors, it is recommended to install double-glazed windows. They not only have high heat-saving characteristics, but also provide additional ventilation of the premises.
4. Installation of internal partitions. To separate the functional zones from each other, it is planned to use special partitions - a wooden frame made of blocks covered with boards or clapboard made of pine, aspen and exotic wood. Such materials are resistant to temperature changes and high humidity.
5. Installation of bath furniture and household items, arrangement of a drainage system.

In order to make the foundation, roof, walls and other parts of the building it will take a lot of money and effort. Not everyone can do it themselves or order it. Therefore, a bathhouse made from a sea container, in my opinion, is an interesting solution to this problem and at the same time very reliable.

You essentially get a ready-made design that you just need to upgrade to suit your needs. It will be necessary to make a pipe outlet, sheathe the building with insulation and wood. It is natural to make a beautiful entrance and shelves for the steam room. Well, of course, you will need to install a heating stove, that’s all that is needed at first glance, but not everything is so simple. We tried to delve deeper into this issue.

Initially, you need to determine where the iron container will stand. Check the site for one level and naturally level it. This can be done either manually or using special equipment. Remove excess debris and consider supporting posts or beams for the frame.

For columns, it is recommended to use concrete or reinforced concrete structures. As a last resort, you can use wooden logs, but as you understand, they will quickly dry out. Approximately 3-4 years and they will have to be replaced.

If you initially installed the sauna container on the ground, then there is nothing to worry about. It’s not even necessary to resort to special equipment. It is enough to have several strong men and use them and a lever to raise the corners of the future bathhouse. We place stops or logs there one by one.

It is also very important not just to remove weeds from the installation site, but to think through all the details. Where will the dressing room be, where is the porch and entrance, and so on. This will help you not to get confused when installing the frame on the site and quickly find your way around.

Quality finish

The assembled iron container requires very serious work and finishing. You must carefully check every inch of the iron and remove the old coating. If you see that there are places with some metal corrosion, it should be removed immediately. All corners and crevices must be eliminated and insulated. You also need to insulate the room from the inside. If this work is not done, the bath will heat up poorly and cool down quickly.

The stages of conversion must be carried out very carefully, because the reliability and durability of the structure depends on this.

Of course, it is advisable to insulate an additional metal frame for the structure and provide hydroprotection to the elements. The base of the frame should be protected from atmospheric influences. It is better to use sheathing and mineral wool.

If you want to improve the appearance of a mobile bathhouse made from an iron container, you can sheathe it with timber. Fortunately, our country has enough timber and its cost is very low. This is quite simple to do. On the Internet and in our article you will see most of the answers to your questions. For safety, before installation, it is better to treat the wood with an antiseptic with fire protection, because we are building a bathhouse, and this means an increased temperature and a risk of fire.

We also protect it from moisture from the inside, because there is always high humidity in the steam room. The floor in the locker room should be insulated so that it does not draw cold from the ground. This is done by paving several layers of boards with mineral wool. Think in advance about the shower drain, if you have one, and about electricity.

Installation of partitions

Which bathhouse project to choose and how to design the room. Logically, such a bathhouse from a container is divided into 3 main parts:

1. Restroom.
2. Wash compartments.
3. Steam room.

It is best to separate these parts in a container using wood. The basis of the partition will be logs that are covered with boards on the outside. But think about the fact that this is a steam room and it will be affected by high moisture and temperature. In order to prevent fungus and other misfortunes from growing there, it is worth treating with an antiseptic. There are quite a lot of building materials on the market now. Choose one with maximum protection from moisture and temperature. It’s easy to coat wood with this chemical with your own hands using a jar and a brush. Apply several times so that all pores are saturated with this substance. Natural impregnations based on wax or oils are perfect. This substance will create a stable film for a long time.

Some builders believe that it is not worth treating walls with such materials and their opinion has a right to life. They believe that when exposed to high temperatures, certain harmful fumes will be released. Yes, if you take cheap Chinese impregnations, then it will be so. If you don’t regret the money, then, of course, there won’t be any evaporation.

For the shelves on which you will sit, I would recommend using an impregnation that does not form a film. Such impregnations are all made on a natural basis and there are a lot of them in any hardware store.

Heating device

At the bathhouse design stage, it is worth considering what energy source we will use. This is an important point, because you will need to think about how energy will be supplied and by what methods. Bath boilers are of the following types, namely:

1. Electrical.
2. Woody.

Depending on the size of the container, 5-20 or 40 pounds, the actual heat source is selected. I would recommend a wood-burning stove, it warms up faster and is more efficient. Well, you should choose the size based on the size of the steel container that will be used as the frame of the building.

In order to provide the bathroom with hot water, it is worth considering in advance the plumbing methods for wiring from the boiler.

Is it difficult to make a sauna from a sea container with your own hands?

Some people think that creating your own sauna from a container is difficult. In fact, everything is much simpler than you think. Any work like this one should be divided into 3-4 main stages. Let's look at the main ones.

1. At this stage it is worth developing a project and plan for the future premises. You need to understand where they will be located and what rooms will be in your bathhouse that you build with your own hands. Determine which container you can buy, because there are quite a lot of them, namely: 40 feet, 20, and 5 tons. Based on the frame, the size of the room and all rooms will be designed. It doesn’t matter that you are building a bathhouse or sauna, planning is an important step.
2. Materials calculation and storage. When you have at least a primitive building design ready, you will know what container or how many containers you will need. If you want to make a really large bathhouse, you can even build it from two containers. So you calculate and transport absolutely all the necessary materials. It is important to bring them at once, because if you miss something, you will be forced to overpay for transportation costs.
3. Construction of a bathhouse. Some are constantly trying to speed up this process, but in vain. Everything must be done on time and according to technology. You must prepare a concrete or wooden base in advance and, if necessary, allow it to gain strength. Then perform each step slowly and very carefully. There is nothing complicated here and almost anyone can do it with their own hands if they follow the instructions in this article. Building a container bathhouse is a relatively quick process. Everyone can make it with their own hands from start to finish in a few months.

Has undeniable advantages:

• built quickly - within 1 month;
• can be built at any time of the year;
• blocks can be connected to each other to obtain a larger area or number of floors, as well as functionality;
• you can do it yourself and build it with your own hands, even without special skills;
• or you can order construction from professionals (or buy a ready-made one);
• high mobility, low transportation costs. You can transport the bathhouse to any place!;
• minimal construction costs (compared to traditional buildings).

The disadvantages of this option are the ability of the container to rust and the lack of heat transfer. These shortcomings are easily eliminated during construction; it is only necessary to ensure high-quality ventilation, hydro, steam and thermal insulation.

How to make a sauna from a container?

Construction stages

1. Choosing a site for construction.
2. Site preparation.
3. Planning the location of the main areas and drainage system.
4. Installation.
5. Zoning, electrification.
6. Insulation and interior finishing
7. Installation of water supply.
8. Selecting a suitable stove and installing it.
9. Installation of communications and flooring.
10. Exterior finishing.

1. Choosing a location

To ensure fire safety, the place for constructing a bathhouse or sauna (not only from the container, but also in principle) must be removed from:

• residential building - no less than 4 meters;
• neighboring areas - no less than 5 meters;
• reservoirs and trails - no less than 20 meters.

2. Site preparation and planning

To begin with, the construction site is cleared of vegetation and debris. The soil is carefully compacted and leveled.

The marking of the territory is carried out taking into account the functional areas of the bathhouse and the drainage system. It would be optimal to arrange a locker room closer to the entrance, followed by a shower room, and then a steam room. This way heat loss is minimized: the boiler is mounted to the internal partition of the steam room to heat the adjacent room. Also, this layout minimizes the consumption of pipes for hot water supply.

The photo shows a project for a bathhouse made from a 20-foot-long sea container.

If you want a larger steam room, purchase a container with a longer length, such as 40 feet.

3. Installation

To prevent water stagnation and corrosion, a bathhouse from a container is placed on piles 25-30 centimeters high. They provide the necessary underfloor ventilation. To do this, a timber frame is erected on a brick foundation. When choosing the height of the piles, take into account that the structure will be tilted towards the drain.

The use of cinder block is undesirable - due to frequent temperature changes and high humidity, it will quickly become unusable. The pitch of the supports is from half a meter to a meter. All wooden elements are carefully treated with an antiseptic and fire retardant. For waterproofing, roll roofing felt is used.

The container is installed on a frame made of piles. To raise it to the desired height, use special levers or jacks. The structure is checked at the building level and, if necessary, adjusted using special gaskets. Corners made of metal profiles are used as clamps.

Upon completion of installation work, the walls, ceiling and floor of the container are treated with an anti-corrosion compound. After this, doors and windows are installed, preferably double-glazed windows.

4. Zoning and communications

The room is divided into several sections. To do this, install partitions: install a frame of beams and cover it with boards.

In the area under the stove, the floor is reinforced with a cement base. Make exit holes:

• in the floor - under the drain pipe;
• in the walls - for ventilation;
• in the ceiling - under the chimney.

Electricity is supplied to the bathhouse and wiring is done to all functional rooms.

5. Hydro- and vapor barrier, insulation

All surfaces of the container are thoroughly cleaned of dirt and defects are repaired. Then a wooden sheathing is constructed and a layer of glassine is laid for hydro- and vapor barrier.

Heat-insulating material with a reflective foil outer layer, for example penofol, is mounted on the walls and ceiling. You can also use pure mineral wool without impurities and cover it with foil. The seams are taped with heat-resistant aluminum tape.

The listed materials are not only effective, but also non-toxic at high temperatures.

6. Interior decoration

For interior wall cladding, siding, antiseptic-treated wooden paneling or ceramic tiles are used. All wooden surfaces are treated with natural oil or wax compounds. They protect against fungus and premature wear, and preserve the beautiful appearance of natural wood. Without treatment, it darkens after 3-5 years.

7. Plumbing

From the place where the stove will be installed in the steam room, a system of hot water supply pipes is installed into the shower room. For free circulation of liquid, it is important to correctly position the water supply elements:

• lower level – heating tank;
• middle level – water supply pipes;
• the upper level is a container with water.

You can buy a tank for heating water ready-made or make it yourself from a heat-resistant metal profile. If there is no connection to a pressure water supply, it is recommended to choose its volume with a reserve so that the water “does not suddenly run out.” The distance from the tank to the wall must be at least 20 centimeters.

8. Furnace installation

The best option for a container bath is an electric or wood-burning heater. To protect against fire, nearby surfaces are additionally treated with a fire retardant. After this, taking into account the natural movement of air in the room, a stove is installed. Then the water supply pipes are connected, electrical equipment and a ventilation system are installed. All communications are laid taking into account current technical standards.

9. Gender

The final stage of interior work is the installation of removable floorboards on a wooden sheathing: this allows you to remove the floorboards for drying. It is recommended to lay two layers of boards, preferably tongue-and-groove, 2.7 centimeters thick. When using pine boards in a steam room, before laying it is recommended to heat the stove and wipe off the released resin before it dries.

Afterwards, bath furniture and household items are installed. Protective oil and wax compounds are not suitable for benches and sun loungers in the steam room - they can cause burns.

10. Exterior decoration

Before proceeding with the exterior finishing, a drainage system and chimney are installed. If necessary, for example, if the bathhouse is two-story, the outer sides are reinforced with a metal frame. The outer surfaces of the container are treated against mold and possible fire. Then they attach hydro- and thermal insulation and cover it with wood or siding.

A container bathhouse is the simplest and most economical way to organize a full-fledged steam room at your summer cottage.

The bathhouse is one of the indispensable places of relaxation, which gives the opportunity to relax not only with the body, but also with the soul. At the same time, all lovers of such useful leisure time know that a home bath is not a cheap pleasure. It is possible to minimize the costs of building your own steam room by building a bathhouse based on a standard block container, which is converted and equipped with all the necessary technical and hardware complex. The original idea of ​​a container steam room has already won hundreds of positive reviews and comments from lovers of such a hot holiday.

Advantages of a bathhouse made from a block container

Arranging a steam room in a container block has several significant advantages over constructing a bathhouse using classical construction technologies.

• Minimum material costs. The cost of a block container, together with the price of its re-equipment, costs the customer several times cheaper than organizing fundamental construction work.
• Mobility. The bathhouse, equipped on the basis of a standard block container, can be transported to a new location at any time. This is especially true when moving. In addition, if for one reason or another the desire to have your own steam room has disappeared, a container bath can always be sold or used to organize your own business.
• Easy heating. Practice shows that heating a sauna made from a block container is much easier than a standard design.
• Speed ​​of construction. A container steam room will please its owner within a few days after the start of construction work, since the entire stage of refurbishment and installation of the unit takes record time.

Features of converting a block container into a bathhouse

It is better to entrust it to professionals who have experience in implementing such projects. Nevertheless, there are some preparatory and facing works that the customer can easily perform independently, without the help of specialists.

• A container steam room does not require pouring a super-strong and reliable foundation, however, to increase the stability of the structure, it is recommended to place a cinder block, brick flooring, and asbestos-cement pipes under the container module. In addition to the main function, such a substrate will also provide the required level of ventilation, which is necessary for any bathhouse.
• Particular attention should be paid to internal and external waterproofing. The external facade is usually lined with wood materials, which allows not only to achieve the above-mentioned insulation characteristics, but also gives the steam room a traditional aesthetic appearance.
• Providing thermal insulation is one of the main tasks in the process of converting a block container into a bathhouse, since maintaining the air temperature inside the module must be maintained not only through the rapid release of heat, but also through its long-term retention. It is important that the internal coating of the walls and ceiling of the steam room can withstand sudden temperature changes.

The idea of ​​building a bathhouse from a container looks quite unusual. It would seem, why equip a bathhouse in a metal box if you can build a light frame building and arrange the bathhouse according to all the rules. Perhaps the idea is worth trying to put it into practice. Well-appointed houses and cottages are built from container structures, why not at least try to plan how to make a bathhouse from a container.

What is the value of a container bath

Making a bathhouse from a container box is relatively easy. All you need to do is develop and plan:

• A system of powerful insulation of metal walls, otherwise in winter the sauna from a container will turn into a glacier covered with condensation, and in summer in the sun the temperature will easily reach 70 o C;
• Ventilation diagram of the internal space and auxiliary insulation cavities;
• Water supply for shower cabin and steam room;
• Installation of a stove or electrical heating connection for lamps and fan drives.

All this is not difficult to do, if not for one “but”. On the one hand, it is possible to sheathe or cover a metal box with bricks, SIP panels, aerated concrete slabs, and problems with room insulation and corrosion protection would be solved. But why then fence a garden with a heavy metal body? Offhand it turns out that it is cheaper to build a bathhouse without a container insert.

Most owners choose to build a bathhouse from a container, photo, if they require:

Important! A container bathhouse does not require a full foundation, regardless of whether it is a bathhouse made from a 20-foot container, or whether it is planned to use several 5-ton boxes. A flat area filled with sand and gravel is sufficient.

Several container boxes, one of which is allocated for a dacha, after finishing and connecting communications, can easily serve as a full-fledged country house.

If the five-ton truck is used as an extension to an ordinary country house, the task can be simplified. For example, make only a steam room out of a container, and use the premises of a country house for relaxation and washing.

After trimming the side walls, the container body can become a frame for arranging an ordinary stationary bathhouse, built in accordance with all the rules and laws of heating engineering.

To do this, you don’t need to purchase a new or a whole container; you can buy a box with holes in the walls literally for the price of scrap metal, and it will be cheaper than:

• Pour the foundation;
• Spend half a cube of high-quality timber on the arrangement of racks and the upper and lower frame of the frame of the future bathhouse.

It will only be necessary to insulate the bathhouse on a container frame and veneer it both on the inside and on the outside of the building.

Container bath problems

Most developers planning to build their own bathhouse on a country site pay increased attention to container-based steam rooms and sauna projects. Often, three factors keep people from building a bathhouse from a container with their own hands, which many private owners are familiar with only through rumors:

• Significant cost of implementing a bathhouse project from a container;
• The metal of the case is subject to severe corrosion;
• In the summer, the interior of the steel container turns into a stove.

The main argument of opponents of the idea of ​​building a steam room from a container is the rather small number of offers of a ready-made bathhouse from a 20-foot container on the real estate market. This is not entirely true. Firstly, most specialized construction companies offer custom-made baths from a container according to a standard design. One of the options, costing about 500 thousand rubles, is given below.

Such a bathhouse made from a 20-foot container photo is divided into three rooms with an area of ​​10-12 m2:

• Steam room with electric stove;
• The second box is a dressing room and a wash room with a shower;
• The third room is reserved for a locker room and a rest room.

The internal space, 6 m long and 2.2 m wide, is lined with clapboard, the external walls can be finished with siding or block house. The price for a finished bathhouse from a 20-foot container is clearly too high, which limits mass demand for the product.

Secondly, there is a certain shortage of sea containers on the market. Companies involved in the production of premises from sea containers buy them in small quantities from carriers. A new or three-year-old box in good condition will cost at least 40-50 thousand rubles. If you set a goal and build a bathhouse from a 20-foot container for yourself, then with some patience you can find a single box in good condition for 25-30 thousand rubles.

How to prevent corrosion

The metal of most container models has practically no special properties. To protect steel walls from moisture and salts, the surface is phosphated and treated with special primers. If you already have plans to build a bath complex, then it is best to equip the bathhouse with your own hands from a sea container.

Such a building will easily last a couple of decades, while ordinary container boxes can be subject to corrosion due to improper ventilation of the steam room and insulation.

Advice! The simplest way to protect a steel body from corrosion is to use zinc or magnesium anodes. The rods are buried in the ground to a depth of 50-70 cm, and the leads are soldered to the metal walls of the room.

Decoration of the facade of a container bath

The rectangular shape of the steel box simplifies the task somewhat. In the most budget-friendly option, the body of the bathhouse can simply be painted in a pleasant color, white or red. Light colors are very popular among developers in the southern regions, where it is important to combat the heat of the sun, which heats any metal in the summer. White paint reduces heat by 30-35%. If we add foil thermal insulation to this, then the problem of overheating can be considered solved.

The second most popular finishing method is wall cladding with a block house, wall paneling or regular siding.

If you add a roof and a wooden porch to the wooden cladding, you can successfully hide the very fact of using a container in the construction of a bathhouse under the outer cladding.

If the bathhouse is attached to the house, then it would be quite logical to line it with the same material as the main building. For country and mobile bathhouse options, it is best to limit yourself to painting the external walls. If the container is new, with factory paint, then such a three-layer coating will last much longer than a semi-handicraft repainting with automotive enamel.

How to properly build a sauna from a sea container

Immediately after purchasing a 20-foot container, the first thing you need to do is check for damage to the walls and places with painted over, putty, rusty holes. A rusty hull costs half the price of a container in good condition, so owners widely use automotive putty and marine paints to mask problem areas. You can identify a hole in the wall with a magnet or a special device.

Which foundation to choose for a bathhouse - container

Despite the fact that a bathhouse can stand for many years even on a simple platform with crushed stone, most owners prefer to install it on a foundation.

A lightweight five-ton container for a steam room is usually installed on columnar supports cast in concrete formwork or built of brick. If the place for the bathhouse is chosen in the forest, or on the shore of a reservoir, then it is recommended to make a crushed stone cushion under the supports. To do this, dig mini-pits according to the number of pillars to a depth of 60-70 cm, fill them with a mixture of fine sand and gravel screenings. Such a foundation will support even a forty-foot container.

Often, the owners of a future bathhouse pour a slab foundation under the container block, motivating their decision with insurance against sagging of the building and the desire to install a second floor in the future. This is not the best option for a bathhouse. The container body is so strong that it will withstand even the collapse of 40% of the supports, and the concrete under the floor will require serious insulation of the bathhouse subfloor.

Insulation of container walls and ceilings

The main issue in building a bathhouse is always the choice of insulation method. At the first stage, the walls and ceiling are sheathed with wooden slats, providing a ventilation gap. Next, the material is selected.

Metal walls can be insulated in three ways:

Thermal insulation based on polyethylene foam and stone fiber must be sheathed with a vapor barrier. A 20-foot container will require at least one and a half rolls of film.

The insulation layer is sewn up with a wooden lath; for a three-room bathhouse you will need at least 80 m2 of linden or ash finishing. The gap between the container wall and the fiber must be ventilated after each visit to the bathhouse.

You can insulate the container space by spraying polyurethane foam directly onto the metal and sheathing slats. Next, a layer of vapor barrier, film and decorative finishing are laid. In this case, the dew point moves to the metal surface of the container.

The most optimal insulation option is considered to be the internal lining of the steam room compartment of the container with stone fiber with an aluminum screen. Layer thickness is at least 50 mm. Next, the outer walls of the bathhouse are covered with penoplex, at least 50 mm thick. The facade of the container is plastered or covered with clapboard.

Arrangement of the bathhouse floor in a container version

Expanded polystyrene insulation is laid on the floor of the bathhouse, onto which a screed of at least 100 mm thick is poured. In shipping containers, the floor is almost always made of thick, moisture-resistant plywood; polystyrene foam and concrete screed can be laid directly on the plywood base.

The next step is to lay a layer of mastic waterproofing over the concrete, install larch logs and install a ventilation system for the underground space. A wooden floor is laid on the joists. Most of the water and condensation that gets on the floorboards will be removed from the subfloor by the ventilation system.

The floor in the dressing room is arranged in a similar way; in the locker room or rest room, you can lay tiles directly on the concrete screed, and a lower level of floor covering will make cleaning the premises easier.

How to deal with condensation inside a bathhouse

The steel walls of a container can become a source of serious problems, primarily due to the metal’s impermeability to water vapor. Even with special treatment of metal parts under conditions of warm condensation and detergent vapors, pitting corrosion can form on the walls of the container. Especially if window openings were cut out, holes were drilled for screwing in self-tapping screws, and laying communications.

Wherever the protective coating has been damaged, the metal will rust. In addition, the wooden sheathing, on which the entire internal lining is supported, easily absorbs moisture even under a layer of varnish or oil impregnation.

There is only one way to prevent container corrosion - by providing effective ventilation. In fact, each room of the container is equipped with its own supply and exhaust ventilation, plus one system for ventilating the subfloor and places where condensation accumulates. Ventilation should be turned on every time lovers of light steam leave the bathhouse and the stove is extinguished. Due to the accumulated heat, the air accelerated by the fans effectively expels condensation at any air temperature outside the container.

Finishing the interior of the bathhouse

According to the standards, the requirements for cladding with wooden slats apply only to the steam room or sauna. In the Turkish bath, the walls of the hot compartment can be finished with ceramic tiles.

The dressing room with shower compartment is lined with wooden panels, clapboard or board. The space for the shower can be separated by a wall and tiled with ceramic tiles. The shower floor is equipped with a drain without a tray, or a plastic shower cabin is simply installed. All parts of the wooden finishing of the bathhouse must be treated with impregnation with fire-retardant additives.

How to properly install a stove in a steam room

Regardless of what type of heater, wood-burning or electric, will be used to heat the container sauna, it is necessary to measure or calculate the volume of the steam room. Based on the resulting cubic capacity, the thermal power of the heater required for the bath and its location are determined.

For a sauna built in a container, the most preferable option would be a wood-burning steel or cast iron heater. It will be difficult to heat the huge steel body of the bathhouse using electricity.

The location for installing the stove is selected next to the partition separating the rooms of the dressing room and the steam room of the bath. The housing is mounted closer to the wall of the container so as not to block the passage and simplify the removal of the pipe. In this case, part of the wooden cladding of the wall behind the stove is removed and replaced with heat-resistant tiles, and the base is laid out of it. A ventilation window is cut out in the wall next to the stove. The second window is cut into the opposite side of the bathhouse wall.

Conclusion

Building a bathhouse from a container is not only a good way to save on materials and labor, it also makes the building safer and all-weather proof. Having installed the steel body on the foundation and equipped the steam room, you can use the bathhouse without waiting for finishing work to be completed in the entire room. The rest is to move the façade and interior details to a period when time and funds become available.
