Condensation in the dressing room, what to do. Condensation in the dressing room in winter: how to get rid of it? A new bathhouse requires new technologies

Eliminating the cause of condensation in the dressing room in winter is not always easy due to the proximity to the most wet areas. But this must be done as soon as possible.

Nowadays, a bathhouse is one of the mandatory holiday attributes for many Russians. Owners of summer cottages and residents of the private sector who have built a bathhouse on their site often encounter the phenomenon of condensation in the dressing room. Water drips from the ceiling, the walls get wet, mold and mildew form, which, in turn, harms not only the structure itself and the things stored there, but also human health.

Eliminating the cause of condensation in the dressing room in winter is not always easy due to its proximity to the wettest rooms. But this must be done as soon as possible.

What is condensate?

Condensation is the name given to moisture that settles on walls and ceilings due to temperature differences. Under the influence of heat from the stove, the water evaporates and is converted into steam, which, thanks to the circulation of air in the room, collects at the boundaries of the room. The walls, ceiling and windows are at the junction of two temperatures. On the one hand, it's warm interior space, on the other hand, the cold from the street. The steam settles on the cooler surface, forming dampness.


A number of factors can influence the formation of moisture:

  • Violations during thermal insulation work. A thermal insulator, for example, polystyrene foam, does not “breathe” simply because it does not allow steam to pass through it, which results in the formation of moisture. Sometimes the reason is the dew point, which is located not outside, but inside the room, causing the walls to become damp and wet. Recall that the dew point is the temperature at which steam turns into water.
  • Violations during installation of ventilation. The temperature in the steam room and dressing room varies significantly and when the doors are opened, steam settles in the room and flows down the walls.
  • High humidity in the room. Water evaporates in the form of steam, collects near the walls and ceiling and forms condensation.
  • Heat air, especially in winter period. The temperature in the bathhouse (dressing room) is always higher than the temperature outside, and in winter this value can be tens of degrees. Steam settles on a colder surface, windows sweat, and moisture collects on the walls and ceiling.




Why is condensation dangerous?

Dampness and high humidity, first of all, are a favorable environment for the development of various microorganisms, fungi, and mold. Wet walls and ceilings often lead to the formation of rot, which can cause the bathhouse to fall into disrepair. Just as mentioned above, all this can adversely affect human health.


How to eliminate the causes of condensation in the dressing room?

One of the most simple ways To remove condensation is to cover surfaces exposed to hot steam with heat-insulating paint. When the bath is warming up, top part The walls and ceiling will heat up faster, which will significantly reduce the amount of moisture formed on them. It is also necessary to insulate the room from the outside, moving the dew point closer to the outer layer of load-bearing walls.

If you are willing to spend one time, you can buy a dehumidifier, which will do all the work for you. It will eliminate excess humidity, which causes condensation, which means that the windows will no longer sweat, the walls will not get wet, and the ceiling will not drip.

Upgrading the ventilation system will help get rid of condensation in the dressing room in winter. One of the easiest ways is to create ventilation holes in the ceiling - strictly opposite each other at opposite ends of the room. This way, excess steam and humidity will escape from the room, and you won’t have to worry about drafts.

Already ready ventilation holes low-power fans can be installed that will help cope with dampness. Do not forget that during procedures in the steam room, all ventilation holes must be closed thick fabric or special valves until the end of the session.



It would also be a good idea to simply ventilate the room after use. Wet walls and ceilings can be wiped with a rag or mop and left open door until completely dry.

Many craftsmen advise installing vaults for water drainage. If you have a so-called leaky floor - gaps are left between the floorboards, then the vault is installed directly under the floor itself and should have a slope towards the drain hole.

In the case of floorboards tightly fitted to each other, the drain is installed in the lowest place. It is imperative to insulate the floor with waterproofing and periodically check its integrity. Craftsmen advise installing valves in the drain to prevent the appearance of an unpleasant odor.




Water from the drain must be discharged outside the building or the bathhouse itself must be built on pile foundation so that the wood dries better and the evaporating liquid does not condense in the bath.

Installing heating devices in the dressing room also helps reduce humidity and eliminate condensation factors. A stove or fireplace heated with wood or heated by electricity will dry the air from steam and prevent condensation from forming.

Don't forget about safety precautions. Any heating devices must be installed strictly according to the rules, because their presence increases the risk of ignition. Do not leave stoves and fireplaces unattended, extinguish the coals before leaving and turn off the power from the mains.

How to eliminate the causes of condensation in the dressing room?

One of the easiest ways to remove condensation is to coat surfaces exposed to hot steam with heat-insulating paint. When the bath warms up, the upper part of the walls and ceiling will heat up faster, which will significantly reduce the amount of moisture formed on them.

Why does condensation form in the dressing room? This question worries many. Any Russian bathhouse has a room called a dressing room. In it, as a rule, people relax after the steam room, store things, other various attributes and a small fuel reserve for the stove.

However, very often the condensation that forms on the walls and ceiling in the dressing room becomes a huge problem, since it is not easy to get rid of it due to the fact that the dressing room directly communicates with the “wettest” rooms.

Build a bathhouse on your own suburban area- this is one thing, but something completely different is proper care for her. Problem high humidity with the formation of condensation, which settles on the surface of the walls and ceiling of the bathhouse, leading to the appearance of mold and mildew on them, as well as wet walls from excess moisture they are subject to very rapid destruction building structures and rotting of wooden parts.

It is rare that a stove is installed in the dressing room, which simultaneously performs the function of heating the room and natural ventilation through her. In all other options for getting rid of condensation in the dressing room, the most optimal and convenient ways ventilation of the bath.

Reasons for the formation of condensation in the dressing room

When there is a low minus temperature outside, which cools the outside walls and windows of the building - baths, and inside this building the air is usually somewhat warmer, then condensation forms on the entire surface from the inside. Excess moisture accumulates, and since in cold times years, drops of water simply do not have time to evaporate from the surface, then it begins to slowly be absorbed into facing material building and thereby destroy it.

Due to the constant temperature change, after a certain period of time, the owner of the bathhouse most often has to replace the bottom boards in the floor, which begin to rot, become overgrown with fungus and ooze bad smell, to new ones.

Why does condensation collect in the dressing room? There are several reasons influencing this process:

  • high humidity;
  • improperly performed thermal insulation;
  • high air temperature;
  • poor ventilation.

Advice from the master!

It is often very difficult, and sometimes completely unrealistic, to identify the main root cause of condensation in the dressing room. However, in order to reduce the content and accumulation of moisture in the bathhouse, and especially in the dressing room after taking water procedures, it is recommended to install an exhaust ventilation system and provide a small window in the room with a window to additionally naturally dry the walls in the dressing room and thereby reduce the formation of water droplets on their surface.

Ways to get rid of condensation in the waiting room

How to get rid of the condensation that has formed on the walls and ceiling in the dressing room in simple and in effective ways? To answer this question, you can offer several options and actions that will help reduce the level of condensation in the bath:

  1. Under the very ceiling, in the opposite walls in the dressing room, it is recommended to make round or rectangular holes under ventilation. The holes must have rectangular sides or a diameter of at least 10 cm.
  2. Low-power electric fans of several W can be installed in the holes provided for ventilation. These fans will forcefully pull excess moist air outside.
  3. IN winter time, if necessary, cover the vent holes with a thick material - a cloth or a sponge while heating the bathhouse - so that the room does not cool down, and then, after all the water procedures have been completed, the holes are opened again.
  4. The ceiling of the dressing room can also be dried by opening the doors from the heated steam room. Thus released warm air will move from one room to another and, of course, will rush upward. Naturally, it is recommended to carry out this activity after completing the main process of staying in the bathhouse.
  5. It is not recommended to paint the waiting room and steam room, varnish it, or dry it in parts wooden products. If necessary, “windy” areas are treated with emery cloth.
  6. The wooden ceiling in the dressing room can be impregnated with antiseptic, antifungal and moisture-resistant compounds that will protect it from blackness, blueness and other unpleasant manifestations. You can apply impregnation to the ceiling using a roller or brush in several layers - for reliability.
  7. It is elementary and not superfluous, after you have steamed, to take an ordinary mop with a rag and wipe the ceiling in the dressing room from the drops of water that have formed on it - condensation.
  8. Reason increased dampness in the dressing room there may also be moisture under the floor, which drains during washing and accumulates there, and then evaporates through cracks in the floor and settles on the ceiling.
  9. Under the floor in the dressing room, it is recommended to install several sheets of galvanized iron with a slope in one direction so that water drains and does not accumulate in the underground.

Conclusion and conclusions

Why does condensation collect in the dressing room and how to get rid of it? This question is not easy to answer, but finding the answer and solving this problem is quite feasible. In conclusion, it should be noted that the dressing room will need to be thoroughly and well insulated, while completely eliminating the appearance of drafts.

Advice from the master!

It is advisable to make the floor in the dressing room from ceramic tiles, since it is not susceptible to rotting and mold.

Preferably after acceptance bath procedures thoroughly ventilate and dry the dressing room, even if regular or forced exhaust is working ventilation system. Good luck!

Bath » Useful information

Many people love to wash in a Russian bath. Why not build it on your country plot? But it’s one thing to build it, and quite another to take care of it. Many bathhouse owners are faced with the problem of high humidity, which settles on the walls and ceiling and leads to wood rotting and the formation of mold and mildew on the walls.

Why does condensation occur in the dressing room and how to get rid of it?

Condensation flows down the walls without drying completely, and this causes irreparable damage to building structures.

What is condensate?

Low in the cold season outside temperature helps to cool external windows and walls, as well as lower the temperature of the heated air in the room itself. When this happens, moisture begins to condense in the air, which flows down the windows and begins to be absorbed into the cladding materials of the building. In the winter season the situation worsens due to the fact that Fresh air cannot replace the wet and so the process called condensation is repeated over and over again. Very often find out main reason The occurrence of condensation can be very difficult, and sometimes completely impossible. The influence is exerted by many factors, including:

  • air temperature;
  • poor ventilation;
  • thermal insulation;
  • humidity.

Is condensation dependent on ventilation?

Condensation on the walls in the dressing room is not a consequence correct installation ventilation. It is known that in the washing room and steam room the air temperature is much higher than in the dressing room. When people leave the steam room, all the steam goes into the room and settles on the walls, flowing down in streams. All this happens due to temperature changes. After a certain period of time, the bottom boards have to be replaced, as they begin to rot, become overgrown with fungus, and an unpleasant musty smell appears. It is necessary that the room has a window with a window, in addition to the main ventilation, this will make it easier to dry the walls and reduce condensation.

A new bathhouse requires new technologies!

When building a new bathhouse, new technologies can be used. Wood paneling the inside can be treated with special antiseptics that do not emit harmful fumes. You can also impregnate the wood with the antiseptic composition “Senezh Ecobio” before construction, protecting the deep layers of wood. After this, treat with special protective coating“Senezh sauna”, it has increased moisture resistance and an antimicrobial effect. At the same time, paint, varnish, dry wooden structures no need. It is recommended to lay ceramic tiles on the floor, which are not susceptible to rotting and mold and will last a very long time. If, when building a bathhouse, ventilation is installed correctly, treat modern materials wood, then these actions can minimize the release of condensation on the walls and floor, which will lead to long-term operation. Take care of your health!The problem of condensation in the bath

How? It is necessary to provide ventilation and hang a fabric curtain over the doorway in the steam room.

In our bathhouse, the relaxation room was once very damp and there was a lot of condensation there. Although the walls and ceiling were normally insulated. Last year I connected the heating to the bathhouse and the problem immediately disappeared. Now the bathhouse is constantly dry and warm. Even when there were frosts of about 40 degrees. I heated it for 2 hours and it’s already comfortable to steam.

Condensation on the ceiling is a fairly typical phenomenon for any cold room, be it a bathhouse or a garage or underground.

If warm or even hot air enters a cold room, then, naturally, when it comes into contact with a cold surface, the warm air turns into water and settles on the same cold surface.

If you haven’t heated the bathhouse all week, and it’s frosty outside, then when it floods sauna stove, all the warm air will rush to the ceiling and “settle” on it as condensation. If you go into the bathhouse after a couple of hours, you will see that there is less condensation, because after 2 hours of heating the walls, floor and ceiling (the entire room) have warmed up and dried to some extent.

In winter, to prevent the bathhouse from condensing, it is necessary to heat it for at least 4 hours, since all structures are frozen and it is necessary for them not only to warm up, but also for excess moisture to evaporate from them.

You've probably noticed that when you come to your dacha in the spring, everything in the house, including clothes, mattresses and linen, is damp. The same thing applies to building structures, be it a house or a bathhouse. In the spring, they need to be warmed up for 3-5 days so that the humidity and cold coming from the walls and floor are no longer felt.

If in winter you heat a bathhouse once a week, on weekends, then you need to come on Saturday, heat it all day to dry, and then on Sunday steam and wash in a normal, dried bathhouse. By the way, this is what all the villagers do: they heat the bathhouse the day before the bathhouse Saturday or Sunday.

With this kind of heating, which warms the bathhouse, condensation will first form not only on the ceiling, but also on the upper logs. In winter, it is better to heat the stove moderately, adding firewood little by little, so that there is no huge emission of very hot air from the stove, so that the heating of the structures occurs more gently and gradually.

It happens that condensation in a bathhouse forms only on the ceiling, even when the bathhouse was heated the day before. Since only the ceiling is cold, this means the reason is an insufficient layer of insulation in the ceiling.

If insulation was done with modern materials such as mats or slabs made of basalt fiber or mineral wool, then for a residential building a thickness of 150 mm is needed, and for a bathhouse, in which the room temperature is much higher, the thickness of the insulation should be 200 mm.

A cold ceiling can be the case when there is no vapor barrier layer, which must be laid before laying insulation made of mineral wool or glass or basalt fiber. Over time, your insulation will pick up moisture and lose all its thermal insulation qualities. You think that you have 200mm there (on the ceiling) good insulation, and there has been nothing there for a long time.

When expanded clay is used as insulation in a bathhouse, the ceiling will also be cold:

  1. Expanded clay is inferior in its thermal properties basalt slabs several times and, accordingly, its thickness should be much greater: no longer 200 mm, but 600, since mineral wool insulation has a thermal conductivity coefficient of 0.045 W/m*k, and expanded clay = 0.15, that is, 3.34 times more, which is 3 times worse for the bathhouse ceiling.
  2. Expanded clay has a fractional nature and the larger the fraction, the more voids there are between the expanded clay pebbles. That is, there is no dense insulation. For insulation, it is necessary to use expanded clay of a minimum fraction of 5-10mm.

To make sure that a large (600 mm) thickness of the insulation layer is needed from expanded clay, simply make a thermal calculation taking into account the average winter temperature for your region (let it be -20 C) and the internal air in the bathhouse premises.

Condensation in the bathhouse on the ceiling of the relaxation room

Another case is when condensation in the bath is on the ceiling of the rest room and only here. In the steam room and washing room - no. Again, in the winter, visit the bathhouse.

The fact is that in the steam room it is 100 degrees, in the washing room it is 50 degrees, and in the relaxation room it is 10 degrees. Naturally, of all the rooms, the rest room is the coldest. To avoid condensation in the bathhouse on the ceiling of the rest room, there is only one way out: in winter, additionally heat the rest room (dressing room) with some kind of electric heating device(heater) to reduce the temperature difference between rooms.

You can specifically warm up the ceiling of the rest room (dressing room) with some kind of wall heater with a directed air flow. While the bathhouse is heating, such a heater will have time to warm up and dry the ceiling of the rest room.

Usually there is no such problem if a five-wall bathhouse with a steam room and a relaxation room, that is, consists of two rooms located in one log house. Moreover, the sauna stove is heated from the rest room. In such a bath, heating of the structures occurs evenly. Accordingly, if there is no cold surface, then there is no condensation in the bath.

Constant condensation in the bathhouse leads to rotting of the wood and an unpleasant odor from mold and mildew. Therefore, when using a bath not only in summer period, but also in winter, you need to consider measures for ventilation and drying of rooms and structures.

If in summer to dry the bath it is enough to open all the windows, doors and lift the floor boards, then in winter you cannot open the door. And, during a week of no heating, everything remained damp wooden surfaces They won't dry out, they'll freeze.

In winter, it makes sense to do a special heating of the bath the next day, with which you can dry those surfaces that were wet after the bath day:

  • cold surfaces in the bathhouse can be not only ceilings, but also windows, if their design summer version(with one glass and cover made of 50mm bars)
  • in a small bathhouse, in the absence of a ventilation system, usually the doors are opened for ventilation and then above the doors (the ceiling and the ceiling around the door) will be wet from condensation (from the collision of warm air with the outside cold air let in through the door)

The reasons for the appearance of condensation in a bathhouse are different. And in each specific case, you need to find it, then somehow solve the problem so that your bathhouse lasts longer.

The problem of high humidity with the formation of condensation, which settles on the surface of the walls and ceiling of the bathhouse, leads to the appearance of mold and mildew on them, and wet walls from excess moisture are susceptible to very rapid destruction of building structures and rotting of wooden parts.

It is rare that a stove is installed in the dressing room, which simultaneously performs the function of heating the room and providing natural ventilation through it. In all other options, to get rid of condensation in the dressing room, the most optimal and convenient methods of ventilating the bath should be provided.

Reasons for the formation of condensation in the dressing room

When there is a low minus temperature outside, which cools the outside walls and windows of the bathhouse building, and inside this building the air is usually somewhat warmer, then condensation forms on the entire surface from the inside. Excess moisture accumulates, and since in the cold season drops of water simply do not have time to evaporate from the surface, then it begins to slowly be absorbed into the facing material of the building and thereby destroy it.

Due to the constant temperature change, after a certain period of time, the owner of the bathhouse most often has to replace the bottom boards in the floor, which begin to rot, become overgrown with fungus and emit an unpleasant odor, with new ones.

Why does condensation collect in the dressing room? There are several reasons influencing this process:

  • high humidity;
  • improperly performed thermal insulation;
  • high air temperature;
  • poor ventilation.

Advice from the master!

It is often very difficult, and sometimes completely unrealistic, to identify the main root cause of condensation in the dressing room. However, in order to reduce the content and accumulation of moisture in the bathhouse, and especially in the dressing room after taking water procedures, it is recommended to install an exhaust ventilation system and provide a small window with a window in the room in order to additionally naturally dry the walls in the dressing room and thereby reduce the formation drops of water on their surface.

Ways to get rid of condensation in the waiting room

How to get rid of the condensation that has formed on the walls and ceiling in the dressing room in simple and effective ways? To answer this question, you can offer several options and actions that will help reduce the level of condensation in the bath:

  1. It is recommended to make round or rectangular holes for ventilation under the very ceiling, in the opposite walls in the dressing room. The holes must have rectangular sides or a diameter of at least 10 cm.
  2. Low-power electric fans of several W can be installed in the holes provided for ventilation. These fans will forcefully pull excess moist air outside.
  3. In winter, if necessary, the vent holes are covered with dense material - a cloth or a sponge while heating the bathhouse - so that the room does not cool down, and then after all water procedures are completed, the holes are opened again.
  4. The ceiling of the dressing room can also be dried by opening the doors from the heated steam room. Thus, the released warm air will move from one room to another and, of course, will rush upward. Naturally, it is recommended to carry out this activity after completing the main process of staying in the bathhouse.
  5. It is not recommended to paint the waiting room and steam room, varnish it, or dry some of the wooden products. If necessary, “windy” areas are treated with emery cloth.
  6. The wooden ceiling in the dressing room can be impregnated with antiseptic, antifungal and moisture-resistant compounds that will protect it from blackness, blueness and other unpleasant manifestations. You can apply impregnation to the ceiling using a roller or brush in several layers for reliability.
  7. It is elementary and not superfluous, after you have steamed, to take an ordinary mop with a rag and wipe the ceiling in the dressing room from the drops of condensed water that have formed on it.
  8. The reason for increased dampness in the dressing room may also be the presence of moisture under the floor, which drains during washing and accumulates there, and then evaporates through cracks in the floor and settles on the ceiling.
  9. Under the floor in the dressing room, it is recommended to install several sheets of galvanized iron with a slope in one direction so that water drains and does not accumulate in the underground.

Conclusion and conclusions

Why does condensation collect in the dressing room and how to get rid of it? This question is not easy to answer, but finding the answer and solving this problem is quite feasible. In conclusion, it should be noted that the dressing room will need to be thoroughly and well insulated, while completely eliminating the appearance of drafts.

Advice from the master!

It is advisable to make the floor in the dressing room from ceramic tiles, as they are not susceptible to rotting and mold.

It is advisable to thoroughly ventilate and dry the dressing room after taking bath procedures, even if a regular or forced exhaust ventilation system is running. Good luck!
