Do-it-yourself ventilation arrangement in the bath

How to make ventilation in each room of the bath?

Let's start with some design points. As noted earlier, it is desirable to draw up a ventilation system project simultaneously with the design of the bath itself. Also, certain requirements are put forward for the process of installing ventilation, which are given below.

• The system must receive enough power to function efficiently and smoothly.
• In the room where ventilation is installed, the temperature should be above zero all year round.
• Finally, take care of soundproofing as well.

What materials may be required?

In order for your ventilation to be maximally protected from various kinds of external negative factors, and also to make it look aesthetically pleasing, be sure to sew it into wooden boxes. Alas, there are no such products on the modern market yet, and therefore you must do everything yourself (or, alternatively, hire professionals for this).

In addition, at work you will need:

• carpentry/industrial tools;
• corrugated pipes (required length - 150 centimeters);
• ventilation grates;
• special sliding systems intended for exhaust ducts.

How to equip ventilation in a steam room?

We talked about the possible ways of arranging ventilation in this room, and therefore we know that two holes need to be made here - for exhaust and air flow. It is worth noting that people who think that it should always be hot in the steam room, and therefore the diameter of the ventilation ducts should be small, are mistaken - this does not comply with building codes at all. And if your holes are too large and you are sure that too much heat is escaping through them, you can simply plug them periodically using a plug made in advance for this purpose.

Even the smallest deviations from the requirements that were described in one of the previous sections of the article can lead to the most negative consequences - from constant cold to the accumulation of toxic gases in the steam room. In a word, position the ventilation holes correctly!

And what about the washer?

Rotting wood, unpleasant odors that accompany this process - all this inevitably awaits every washing room where there is no floor ventilation system.How to take care of it? Let's make a reservation right away that there are practically no special differences, if we compare everything with the same steam room.

In order to equip ventilation here, be sure to follow these steps:

• making holes between the rough / finish flooring;
• removal of the ventilation pipe to the roof;
• installation of a fan on this pipe.

thanks to the use of a ventilation system in the bath, the heating of the floor will be carried out approximately as follows: the cooled air, which we also call exhaust air, will be brought out through the pipe, and instead of it, already warm air will fall (from the upper layers located under the ceiling). Moreover, due to the relatively low air flow temperature, for this purpose, even a plastic box can be used more fully.

We take care of the ventilation system in the dressing room

The air exchange features here are practically the same as in the options described above, so the ventilation in the bath in this case should be similar. First of all, what is it for? All the same, in order to bring the exhaust air outside and deliver fresh, oxygen-rich air into the room. And the circulation of air masses must be arranged in such a way as to ensure high-quality ventilation and drying not only of the room itself (that is, the dressing room), but also of all pieces of furniture and decor in it.

Experienced bath attendants know that the main difficulty of any dressing room is nothing more than condensate - it forms in large volumes here on the ceiling and walls of the room. Because of this, people have to face the most horrific consequences, including the appearance of mold and various kinds of fungi, which, in turn, provokes premature decay of the tree. To avoid all these unpleasant things, the dressing room needs high-quality thermal insulation, which will allow you to forget even the slightest hint of drafts.

In some cases, stoves are installed in the dressing rooms. If you have the same, then the problem of air exchange in this case disappears as such, since both the inflow of air and its outflow will be carried out precisely through it.

General rules for installing the hood in the bath

Standards for ventilation of premises are regulated in SNiP 41-01-2003. These documents refer to the establishment of the air exchange rate in various rooms, depending on their purpose and application features.

For a bath, these tasks are hampered by the fact that the ventilation system must quickly displace moist air, and at the same time maintain the optimum temperature in the steam room.

In addition, it must be borne in mind that bath procedures are taken by people of different ages. In addition to the steam room itself, situations may arise when the stove still gives off heat, but children need to wash themselves. To regulate the temperature here, one cannot do without ventilation, because without it it will not be possible to quickly ventilate the room and reduce the temperature to the desired values.

Dependence of the bath ventilation system on the type of building

In a log and timber bath, a natural hood perfectly justifies itself, but on condition that the vents are correctly located and they correspond to their given dimensions.

If the bath is frame, then it is understood that it is airtight. Therefore, to ensure the flow and uniform circulation of air, a fan must be installed in such a room.

Bath and sauna, built of brick, cinder blocks or foam blocks, are provided only with artificial ventilation.

Performing work on the installation of ventilation systems

In the baths, both supply and exhaust ventilation systems are calculated. Their work is balanced by the influx of not only fresh air from the street, but also taking into account the inflow or outflow of air from adjacent rooms.

In the steam room, ventilation for the bath is also allowed exhaust or supply. In this case, air circulation occurs from the dressing room through a special hole or flows into an adjacent room.

Natural air exchange in a wooden bath is the cheapest option. This is due to the fact that in the walls, already during construction work, you can simply leave holes of the required diameter.

Hole in the wall for natural ventilation

Metal or plastic air ducts are mounted in them, and gratings for air circulation are installed on the outside. In this case, such an extract must be equipped with an adjustable damper.

It is covered to a greater or lesser extent, depending on the season of the year, or when the room is warmed up. The installation site of the ventilation duct must provide a stable air flow, on the one hand, and free access to it, on the other.

In baths, forced ventilation equipment is installed from the outside in through holes, and the control is located in a room with low humidity: a dressing room or in a rest room.

During operation, all structural elements of the bath are subject to high humidity - this is especially true for wooden products. To neutralize the effects of humidity, there is an outlet in the basement through which fresh air penetrates to the wooden floor, drying the room.

Sometimes such an element is an integral part of the air flow in the general ventilation system.

Conclusion

In a small steam room of a Russian bath, competent ventilation is the key not only to your health, but also to safety in general, and it doesn’t matter what the bath is heated with: wood, coal or electricity.

Cleansing the air from harmful impurities, comfortable heat exchange directly depends on it, and only then the bathing procedure will be favorable.

Recommendations before you start

Pay attention to the installation location of the sauna stove. If the stove is located right in the steam room, then natural air exchange is present initially

You just don’t need to rely solely on it - such ventilation only works when the stove is running.

Ventilation

It is not recommended to place the ventilation holes too high. Although in most other cases it is recommended to make an exhaust hole directly under the ceiling, slightly different rules apply in baths.If you place the hood directly under the ceiling, hot air will leave the room very quickly.

Extract for a bath: in which department?

If we leave aside the issues of ventilation of walls, foundations and roofs already discussed in other articles, there are rooms - a steam room, a washing room, a dressing room and a rest room - where you need to organize air circulation. At the same time, there are certain standards regarding ventilation in each of them and the specifics of the manufacture of the hood. But first things first.

Extractor in the steam room

For steamers, the hood in the steam room of the bath is a guarantee that they will come out of there alive and healthy.

IMPORTANT! You can not leave the steam room without ventilation holes at all, this is a big risk of getting black or losing consciousness and suffocating with carbon dioxide. You can’t make only one hole - this is how ventilation does not work .. The method of ventilation of the steam room can be natural (due to the laws of physics) or forced (due to fans)

Openings can lead to the street, to air ducts and to neighboring rooms. On the ventilation openings, either blinds or dampers are placed. Air inflow can be organized through the bottom of the steam room door, spaced 3 cm from the floor or with blinds at the bottom of the door leaf

Air inflow can be organized through the bottom of the steam room door, spaced 3 cm from the floor or with blinds at the bottom of the door leaf.

With your own hands you will have to make only a box.Everything else (corrugation, valves, gate valves, dampers) is on sale. Fans (if needed) vary in diameter and power. For automatic control forced ventilation, you can use a relay. Holes in the wall are either left during construction, or they make their way in an already built bath.

See how the craftsmen made a box for extracting ventilation from the boards:

In the washing

According to the already mentioned standards, the air circulation in the washing room per hour should be a multiple of 8 room volumes. for forced ventilation and 9 - for the hood. It means:

• that the dimensions of the exhaust opening will be larger than the inlet;
• or there will be two exhaust outlets per one inlet;
• or a fan is installed on the hood.

In any case, this is an intensive air exchange, which is intended primarily for quickly draining the car wash. During the washing process, it is not required, so it is regulated by dampers.

By the way, air inlets can be made in the dressing room or rest room, and exhaust holes in the washing room. This will allow you to ventilate two rooms at once. Similarly, the hood is done in the bathroom, and forced to create low pressure. Then the air will be drawn from the neighboring rooms and leave through the forced exhaust. Thus, the rooms are connected by through holes, which on the one hand will be supply, and on the other - exhaust.

The components of the hood in the washing bath do not differ from those used in the steam room.

The ventilation system in the bath: what can it be?

Ventilation systems in baths are divided at once according to several parameters:

• forced or natural;
• exhaust, supply or supply and exhaust;
• local or public.

Let us explain that forced differs from natural by the presence of fans that forcibly drive air in or out, local differs from general exchange by its local character, for example, the chimney above the stove is local ventilation, and vents are part of general exchange.

As for the supply, exhaust and their combination, these are indications of which air is directed where: the exhaust drives the exhaust air out, the supply air drives fresh air in, and their combination creates a balanced air exchange inside the room.

These are general terms for any ventilation, but our task is to consider a bathhouse that has its own specifics. We advise you to familiarize yourself with the dependence of ventilation on the type of bath (8 types).

Watch a short video, as one of the options for organizing ventilation in the bath:

Natural ventilation in the bath

It works on the principles of physics, which say that heating makes air lighter and causes it to rise. And an increase in the volume of cold air accelerates the movement of hot air. Knowing about this property, you can not install any devices at all, there are enough ventilation holes, the location of which will make some of them supply air, and others - exhaust.

And in the bath there is a stove, and this is a very favorable circumstance for the direction of air circulation. If a natural ventilation inlet located near the floor next to the blower, then the stove itself will draw in fresh air, without any fan. Also, raising the finished floor just above the hole under the firebox contributes to improving traction.

The exhaust opening is usually made on the side that is opposite the wall with the supply opening, but this is not the only option.

Forced ventilation

If fans are placed in the same holes, then you can not be afraid of calmness or other weather conditions that adversely affect the air circulation in the bath.

In principle, there is no big difference between natural and forced ventilation in the circuit itself, it is only a matter of which holes the fans are in. Because you can not put them everywhere, reinforcing only the exhaust or only the inflow. But by creating a large difference between the inflow and outflow, we change the pressure in the room. This is easily detected by the way the door slams. The task is to create a balance between outflow and inflow, and the air during bath procedures should circulate slowly, without causing a draft. And when drying, a draft is only good.

IMPORTANT! The direction in which the fan drives the air depends on the location of its blades, so it is important to ensure that there is no exhaust fan in the supply opening and vice versa.

Types of ventilation

There are two types of ventilation:

• natural;
• forced.

Which one to choose when installing a ventilation system with your own hands depends on the design of the bath and the volume of its premises.

Ventilation system with electronic control unit

natural ventilation

This type of ventilation works due to the difference in temperature and pressure inside and outside the room. The efficiency of its work depends on the location of the openings for the inflow and outlet of air.The most suitable solution - the supply openings are located near the floor, at a height of 250-350 mm, next to the stove, and the exhaust openings are on the wall opposite them, below ceiling level on 150-200 mm.

Natural ventilation systems are not suitable for ventilating a steam room or steam room, since the cold air in this room collects at the very floor, and the hot air in the upper part. Adjusting the movement of air flows is accompanied by difficulties, but with the correct arrangement of the ventilation elements in the steam room of a Russian bath, it is possible to cope with this problem with your own hands.

Natural ventilation is not suitable for a steam room, it is advisable to equip it in a rest room

Forced ventilation

For this type of ventilation in the steam room of a Russian bath or sauna, two subspecies can be distinguished:

Ventilation with the help of special electronic systems that control the temperature and humidity of the air, regulating its flow and filtration with the help of automation. Such systems are quite expensive, and their use is often knocked out of the budget.
Combined ventilation systemwhen, through the use of fans, the effect of natural ventilation is obtained.
