Some experts say that if you wish, a real Russian steam room can be arranged even in a fairly spacious bathroom of an ordinary apartment. We will make a reservation right away. You can steam with a broom in such a mini-bath, but getting real dry steam is very difficult. After all, this requires a sufficiently powerful and heavy stove-heater. It is much easier to equip a mini-sauna in the apartment.
How to build a mini-sauna in a city apartment and make a steam room in the bathroom, construction steps, features of using a mini-sauna, choosing a stove in a sauna.
In order to build such a sauna, any easily ventilated room should be at our disposal. The floor must first be tiled. If the bathroom is equipped with a sauna, you need to bring the ventilation duct from the sauna directly to the street.
For example, through a kitchen window. Do not connect to the general ventilation uniting the ventilation ducts of all the apartments of your house or entrance. The air here is poor in oxygen and is not suitable for a sauna. If you managed to solve this problem, you can purchase the necessary materials and begin construction.
Stages of building a sauna in a city apartment.
Electrical wiring and installation of the sauna frame.
The construction of a mini-sauna should begin with the installation of a vertical frame of timber. At the same time, the door is installed and wiring is done. The shape of the frame can be different depending on what part of the room is reserved for the sauna. As for the wiring, a professional electrician should do it. After all, to power the furnace of the required power, you need to have a separate power wiring of 4-6 mm with double insulation.
In addition, a separate phase and zero should be brought to the furnace. If this is not done, then when connected to a single-phase network, the wires for low-power consumers may not withstand the load and catch fire. To reduce the fire hazard, bricks must be laid under the stove. It is possible to make a lining around the oven on three sides of brick or ceramic tile..
Installation in the sauna of a horizontal frame from a smaller beam.
An external horizontal sauna frame is installed from a smaller diameter beam. It is needed to secure the external cladding and helps create an air gap between the walls and the vapor barrier. At the same stage, the frame is sheathed with boards along the outer contour.
Heat and vapor barrier of a sauna steam room in a city apartment.
Any heat insulator is suitable for this (if it does not contain impregnations harmful to health). As a vapor barrier, foil is most often used. And at first, a heater is placed in the interpanel space, then foil. The ceiling is insulated with a double layer of insulation. After that, the internal horizontal frame is installed, on which the lining is then attached. This skeleton helps to create an air gap between honey and steam lining..
Finishing the ceiling and walls of the sauna with clapboard.
The walls and ceiling are lined with clapboard. It is best to use a Euro profile lining with a tongue of at least 8 mm for this purpose in the sauna.
Installation of shelves in the sauna.
First, frames are made. If the area allows, it is better to install two shelves: one closer to the ceiling (about a meter away from it), the second closer to the floor. In this case, the lower shelf will also serve as a stepping stone. If you arrange the lower shelf at a height of half a meter from the floor, you get a very convenient design. Both shelves are best made from aspen boards, and their thickness should be at least 4 cm.
Some experts recommend making a centimeter gap between the boards so that sweat can flow freely through these slots. Through these same slots, cooler air can also flow from below. This is not very pleasant, so just below the shelf-bed, you can install another, internal, shelf-screen. It needs to be made solid, and the space between these shelves can be filled with healing herbs. They will absorb sweat and create a pleasant aroma in the steam room..
Installation of a sauna stove in a sauna.
A practically finished sauna is equipped with a stove-heater of the required power. For our purposes, any electric furnace with a dry air mode is suitable. Most often, air heaters with a power of 2-3 kW are installed in furnaces. You can purchase a branded sauna stove. In this case, you will have at your disposal a safe, easily adjustable electric furnace, which will help you create various steam modes in your sauna.
When choosing power, the stoves are guided by the following rule. Each cubic meter of volume requires about 1 kW of power. But this only applies to small saunas. Between the furnace compartment and the shelves it is best to install an impenetrable partition made of boards lined with clapboard. This will allow you to create the right steam circulation and protect you from burns with superheated steam.
Checking the ventilation system.
Air from the street must be forced down to the furnace compartment. A flap is installed to adjust the air supply. After that, a silent fan is installed under the ceiling opposite the shelf. It will allow you to create a fairly low humidity in the steam room, improve the process of evaporation of sweat from a heated body. If you still can’t lower the humidity, you can use a fan heater.
Installation of luminaires, boardwalks or removable wooden grilles in the sauna.
The floor (fixed or removable) must have a gap between the floorboards (at least one and a half to two centimeters). This will help to dry it well if necessary. Electric lamps in the mini sauna need to be protected with a hemispherical grill for safety.
If you decide to arrange a sauna in the entire bathroom area of a city apartment.
If the sauna covers the entire area of the bathroom, adhere to the above sequence with the exception of some nuances. Firstly, you do not need to install a freestanding wooden frame. You can simply insulate the walls and ceiling of the bathroom with any heat insulator (insulated, foam concrete, asbestos chips, felt, even an old bike blanket will do).
Instead of a frame made of timber, use slats with a thickness of 3&# 215; 3 cm. The walls and ceiling are upholstered with slats (the distance between the slats is approximately 0.5 m). A heat insulator is laid between the rails, thin boards are fixed on top of it, between which a foil is laid. Then you can sheathe the bath with planed boards. The support for the stove needs to be made not only of brick, but also of thick slate.
Security measures if you built a sauna in the entire area of the bathroom.
Since the bath in this case is inside the steam room, you should think about safety measures.
The stove should not be placed directly next to the bathroom and at the same level with it..
The power outlet must be outside the steam room.
The electrical cord must be well insulated and routed along the wall..
Carrying is not allowed; the cord must never be pulled on the floor..
If instead of a branded sauna heater, a conventional dry-air electric furnace is used, it must be loaded with stones.
Features of using a mini sauna, getting steam.
Since there is not enough space in the bathroom, the removable shelves will have to be fixed directly to the bathroom. All nails need to be “drowned” in a tree; metal handles on a door should be replaced with wooden ones. That’s probably all.
It remains only to turn off all electric heaters in the house and turn on the stove. If this is not done, it may “knock out” the cork. The wood for cladding should be well dried. The drier the boards, the higher the temperature in the sauna. If you like wet steam, you can pour some hot water into the bath.
As already mentioned, in a home mini-sauna it is impossible to get dry saturated steam, for this you need to have a very powerful source of heat. A powerful electric furnace can only be installed if there is a supply of electricity through three-phase wires. It is theoretically possible to do this in a modern apartment building (for example, pottery workshops with muffle kilns for firing are sometimes equipped just like that), but in practice this is rare.
But you can still take a steam bath in such a mini-sauna. To get steam you need a birch or oak broom. It is steamed in warm water for no more than 10-15 minutes, then raised to the ceiling and shaken vigorously. A white cloud of steam forms near the broom. This broom pair is enough for a few claps in the body. After that, you need to dip the broom in warm water. Just don’t get carried away, otherwise waterlog the steam room, and it will have to be dried.
Choosing a stove in a mini-sauna arranged in a city apartment.
The most difficult part in building a home mini-sauna is choosing the stove with the right capacity. Too powerful a furnace is fire hazardous, moreover, it consumes a lot of electricity and occupies a large area – after all, powerful furnaces are usually large. We don’t need any extra energy costs, and there’s not much usable space for a sauna in the apartment.
At the same time, a weak stove will heat up the steam room for a very long time, it will need to be turned on more often to maintain the desired temperature, as a result, it will quickly wear out. In addition, the humidity in the steam room heated by a weak oven will be high. Consult with experts. Perhaps your choice will be limited to a safe pendant oven that does not require additional insulation between the stove and the wooden lining of the bath.
It will not be difficult to purchase special heat-resistant and waterproof luminaires. They are, of course, more expensive than usual, but for the sake of safety it is still worth listening to our recommendation. In any case, all wires must be heat-resistant, ventilation should exclude spontaneous combustion.
It should also be taken into account that if there is masonry in the steam room that is not sheathed in wood, the stove must be selected with even greater power. For each square meter of masonry, add another 2 cubic meters to the calculated volume of the steam room. It is much easier to completely cover the brickwork with wood..
Selection of wood in a mini-sauna.
The wood used to build a sauna in the apartment is the same as for a freestanding sauna. Outside, it can be sheathed with larch or spruce. They have almost no tarry odor. For interior decoration, walls, ceiling, aspen or linden. Well, if they underwent special heat treatment, then the service life of the wood will be long. Shelves can also be made from aspen. Some people prefer poplar.
Door to the mini sauna.
When building a mini-sauna in the apartment you need to install a small door (no more than 70&# 215; 190 cm). This will avoid heat loss during a visit to the steam room. The appearance of the door is a matter of your taste. Doors can be solid wood, and with built-in glass inserts – portholes. Among lovers of exotic lately glass doors have been especially popular..
For their manufacture, a special heat-resistant non-fogging tinted glass is used that visually expands the volume of the steam room. This is important, especially if the steam room is small. In addition, glass doors to the sauna are ideal for people who cannot tolerate enclosed spaces. However, supporters of the traditional bath still believe that no glass can replace a tree that gives the steam room a natural, pristine look.
