Is it possible to install a gas boiler in the bathroom?

Owners of country real estate at the stage of designing a heating system very often have a question: are there regulations allowing the installation of a gas boiler in the bathroom or should such an arrangement be immediately excluded?

You won’t believe it, but the question is really relevant, so next we will help you figure out whether there are any restrictive standards or not, and also whether it is worth entering into disputes with gas workers in court for the right to install a boiler in the bathroom or is this wasted time.

What do you need to know when installing a gas boiler in a bathroom?

When looking for a convenient place to install a gas boiler, owners often stop at the bathroom or toilet. But to what extent is such placement allowed by SNiP rules and fire safety standards? Before installing a gas boiler in the bathroom, you should understand this issue in detail.

You are unlikely to find a clear answer to the question of whether it is possible to install a gas unit in a bathroom in the documentation. According to SNiP standards of 1987, the placement of such equipment in the bathroom is prohibited. However, later, since 2003, the cited SNiP was declared invalid and instead SNiP 42-01-2002 “Gas distribution systems” was put into effect. But it does not clearly indicate whether a gas boiler can be installed in a bathroom. You can only get an affirmative answer by contacting your gas supply company.

Important! Only a device with a closed, hinged combustion chamber can be installed in a bathroom or toilet. As practice shows, most gas workers prohibit the installation of gas equipment in the bathroom. The main reasons for refusal are the following:

The main reasons for refusal are the following:

As practice shows, most gas workers prohibit the installation of gas equipment in the bathroom. The main reasons for refusal are the following:

• requirements of old standards;
• insufficient room size;
• high humidity in the bathroom, which leads to rapid failure of equipment;
• interruption of traction due to mixing of moisture with combustion products.

It’s easier for those who already had a gas boiler in their bathroom or toilet. Then they replace the old unit with a new one without much paperwork.

However, some owners resort to tricks and, in order to obtain permission from the gas service, pass off the future bathroom as a furnace room. And after installing the unit, a shower and sink are also placed there. But such a violation is fraught with negative consequences in the form of fines and disconnection from the gas main. The fact is that gas workers are required to periodically check the gas equipment located in the house, so in a year or two the fraud will still be discovered and you will have to pay dearly for it.

If, despite the refusal, you are ready to continue to seek permission to install the unit in the bathroom, then you can go the following way:

1. You need to submit a request to the head of the gas service to connect a heating device in the bathroom. In this case, you should attach a list of regulatory documents that allow you to do this.
2. If you are refused, you can file a claim in court, where you can always win the case.

Pros and cons of installing a gas boiler in the bathroom

Many people are attracted to installing a gas device in the bathroom for the following reasons:

• compact location;
• the unit is not “conspicuous” and does not interfere with movement;
• hot water is immediately supplied to the main water intake points - the sink and shower.

There are also disadvantages to this arrangement:

• high humidity negatively affects the metal parts of the device;
• bathrooms usually have small dimensions, so even a compact wall-mounted unit will take up quite a lot of space;
• there is a high probability that in order to meet all safety requirements, the bathroom will have to be re-equipped.

Think carefully about whether such placement of a gas boiler is suitable in your case. Perhaps the best installation option would be a kitchen or hallway.

What requirements must a bathroom meet?

It is important to understand that not every bathroom is suitable for installing a gas boiler. For example, standard bathrooms in ordinary Khrushchev or 9-story buildings built in the 70s and 80s are too small and do not have sufficient ventilation. In order for it to make sense to even consider the possibility of installing a gas boiler in the bathroom, it must meet certain requirements:

In order for it to make sense to even consider the possibility of installing a gas boiler in the bathroom, it must meet certain requirements:

• total area of ​​at least 7.5 m²;
• the presence of a working ventilation system;
• there must be a window with an area of ​​at least 0.25 m²;
• ceiling height not lower than 2 m;
• when the door is closed, there should be a gap of 1-2 cm between it and the floor;
• there should be nothing in front of the unit at a distance of 1 m;
• Bathroom walls must be made of non-combustible materials.

Thus, from the above requirements it is clear that apartment owners in multi-storey buildings are practically deprived of the opportunity to install a gas boiler in the bathroom. The owners of private houses have a better chance, since they can initially build a bathroom that meets all the given standards.

Types of water heating equipment for the bathroom

Today, the range of devices for heating water is very wide and varied. The choice of equipment suitable for household needs depends on how many liters of water per day each family member needs. In addition, when purchasing a water heating device, it is necessary to take into account the following indicators:

• Energy source
• The location where the unit will be installed. For small apartments, it is advisable to choose compact water heating devices.
• Safety.
• Source of energy consumed.
• The amount of gas or electricity consumed.

If a number of problems may arise with the installation of gas-powered units in the bathroom, then the installation of water heating equipment in such parts of the house is permitted. That is why most apartment owners use storage tanks to heat water, which also provide heating for the bathroom.

Currently, the most common water heating devices are:

• Storage units for heating water.
• Instantaneous water heaters.
• Single-circuit and double-circuit boilers.
• Thermostatic mixer-water heater.

Chimneys and ventilation

Existing state standards for the placement of gas boilers in the private sector provide for requirements for the safe organization of air exchange, for example, the ventilation system must uninterruptedly ensure three times renewal of the air environment within one hour, otherwise the operation of the unit will be stopped due to a lack of oxygen during the preparation of the gas-air mixture. Insufficient air exchange causes the formation of large amounts of carbon monoxide, which is dangerous to others.

Forced ventilation is installed in the room to supply clean air and remove carbon monoxide. The supply duct is installed opposite the unit, as close as possible to the entrance door opening. The internal diameter of the flue must be equal to the boiler smoke outlet pipe and be at least 110.0 mm.

The first 5 m in the gas duct at the boiler outlet are made of heat-resistant metal, then other heat- and chemically resistant materials are used. According to the requirements of the SES, the use of materials containing asbestos in residential premises is prohibited.

Technical requirements for equipment

The piping system of the boiler is also regulated:

1. Install the tanks on the bases and fix them with anchor bolts.
2. If there are two circulation pumps - one is placed on the return line between the boiler unit and the separator, and the second - on the supply after the separating column.
3. A safety relief valve is installed on the supply line of hot coolant from the boiler to protect the equipment from overpressure.
4. The drainage line for emergency drainage from the boiler must not be connected to a plastic sewer.
5. To automatically recharge the heating circuit, a make-up regulator is installed on the water supply.
6. Gas pipes are installed only from metal.
7. Installation of a gas meter on the boiler is mandatory.
8. Boiler equipment must be well grounded, and the quality of grounding must be checked annually by a specialized organization.
9. A gas analyzer must be installed in the boiler room to warn of gas leaks. In case of danger, it transmits a signal to an automatic shut-off valve to emergency stop the gas supply.

Nuances and requirements for attached boiler rooms

Full compliance with state standards and requirements for the premises for placing a gas boiler will help the owner to avoid fines and supervisory authorities, but also to prevent the occurrence of explosive situations during operation. When placing a boiler room in basements or basement rooms, it obliges the owners to install a door in such a room with a separate exit to the street.

When placing a gas boiler in the basement, it is necessary to install a door with a separate exit

Installing a gas boiler in an extension requires that it be placed against a wall of the house that does not have glazing. The requirements of SNiP 41-01-2003 and MDS 41-2.2000 set the minimum distance of such a unit to the window - at least 4 m. The manufacturer of gas equipment for boiler circuits took care and indicated the exact boiler installation diagrams for different types of premises. Such information must be provided to the user with a passport and operating instructions.

What to do after redevelopment

When the apartment owner completes repairs, he must update the technical passport:

1. An inspector from the Housing Inspectorate is called to the house.
2. The owner receives hidden work certificates from the construction company that carried out the renovation.
3. The owner of the apartment receives documents confirming the reconstruction from the inspector.
4. A BTI technician is called to your home to take measurements of the premises.
5. After some time, the BTI issues a new passport.

Remodeling a bathroom and toilet is a complex but completely doable process. If you find an experienced contractor who takes a responsible approach to construction, or thoroughly study all the issues regarding redevelopment, then you can agree on a plan and obtain permission without unnecessary nerves and waste of time.

It is important to remember that demolishing the partition and changing the position of some plumbing parts is possible in a simplified manner. But enlarging the restroom or partially relocating it is a more complex procedure that requires a full BTI inspection and the preparation of a package of documents

Requirements for organizing the boiler room

If the boiler power does not exceed 200 kW, any built-in rooms in the house can be used as a boiler room. These include basement and basement rooms. For boilers with a power of up to 30 kW, the minimum room volume must be at least 7.5 m³. Accordingly, for equipment from 30 to 60 kW - 13.5 m³, more than 60 kW - from 15 m³. You also need to take into account other characteristics of the boiler room.

These include the following requirements:

• ventilation opening area for gas boilers up to 30 kW – 0.02 m², from 30 to 200 kW – 0.025 m² (read about boiler room ventilation here);
• the distance from the protruding parts of the equipment to the walls is regulated by the manufacturer;
• the presence of a transom or window to reduce gas concentration in the event of a leak, providing three air changes in 1 hour;
• natural and artificial lighting of the room, the ratio of window area to volume is 0.03 m² per 1 m³;
• if the boiler room is located on the first or basement floor, a separate passage must be installed, the door must open outward;
• ceiling height – at least 2.5 m;
• On the walls in the boiler installation area, fire-resistant material is installed, the fire resistance limit of which is at least 0.75 hours.

The placement of heat supply components is free. The main requirement is that nearby objects should not interfere with repair or maintenance work.

Beautiful examples

Having a window in the bathroom that leads to the kitchen is not always a problem. In some cases, this makes it possible to take a shower in the daytime without turning on the light, and for those who like to steam, there is a chance to quickly ventilate the room and refresh it. In order for a window opening to fit into a modern design, you need to be able to decorate it correctly and use it based on your own needs.

Using glass blocks instead of regular glass is a good way to keep the room light, but at the same time decorate it and give it a completely different look. The drawing should fit into the design of the room and complement it. The color range of glass blocks can be different, everyone has the right to choose what they like.

Stained glass is an equally beautiful option for finishing a window opening in a bathroom. The use of original and custom designs can be captivating and promote relaxation while taking a bath. The stained glass pattern should be such that it looks equally good in the bathroom and kitchen, otherwise one of these rooms will look awkward with stained glass.

The shape of the window plays an equally important role in interior design. If the apartment is designed in a modern style, then a round window opening will be a real find and will complement the concept of the room. The size of a round window can be any size, from small, about 30 cm in diameter, to large, 60 cm or more. The use of stained glass or other decorative elements in this case will be unnecessary, as it will distract from the originality of the frame itself and the illusion of being on an underwater or ordinary ship.

If there is no possibility or desire to change the size and shape of the hole for the window, but you want to make it special, then the simplest solution would be to choose platbands in a non-standard color scheme. The most common color is white, so many people want to install a window in any other color to stand out and make their apartment unique. The wood-colored frame looks very beautiful, expensive and stylish, and goes well with almost any interior, which is very convenient.

For those who do not see the need for a window between the bathroom and the kitchen, it is possible to transform a niche into a useful space and instead make a shelf for useful small items or decorative elements.

Supporters of creativity can decorate the window in an original style, showing all their resourcefulness and talent. Each option deserves consideration, so it's worth considering all the possibilities before making any decision regarding a bathroom window.

What types of boilers can you get a permit for?

In some regions, the installation of water heating systems with a closed combustion chamber is permitted. Therefore, before purchasing equipment, you should familiarize yourself with its technical characteristics and design, and also consult with a representative of the Gas Service.

You can obtain permission for boilers with a closed combustion chamber.

What do you need to know when installing a gas boiler in a bathroom?

To determine whether it is possible to place a gas boiler in the bathroom, you will have to carefully study the current building codes and regulations and evaluate the existing premises. Here it is recommended to first decide for yourself whether a gas boiler is needed in the bathroom at all. Traditionally, in private houses or cottages there is a special room for such devices, equipped with forced ventilation and meeting all the conditions for furnace and boiler rooms. The location of the boiler in the bathroom is a somewhat non-standard option, although in Soviet times it was allowed to combine a bathroom and a furnace in low-rise buildings in the private sector. But this was most likely an exception, and in the future, when replacing old gas equipment with new appliances, gas workers usually refused permission to install a gas boiler in the same place in the bathroom. Today, if you are guided by existing standards and fulfill all the technical conditions for this premises, it is quite possible.

The second no less important point that you will have to take into account is the requirements of gas equipment manufacturers for the installation site. The bathroom, even if all the nuances of ventilation and size are observed, will still be a room with high humidity

And high humidity, as we know, is one of the reasons why service centers will quite reasonably remove the device even with a partial warranty. Alas, control boards for gas appliances remain very sensitive to high humidity.

Sanctions for violation of norms

In case of violation of the requirements for the installation of gas-using systems, penalties may be imposed, followed by shutdown of the fuel supply and other unpleasant consequences.

Equipment is checked once a year, so during the next scheduled inspection, gas service employees may issue a fine.

If the mandatory rules of the joint venture regarding gas supply are ignored, the violator faces being disconnected from the main pipeline within 40 days.

In addition, leading boiler manufacturers will remove the warranty on appliance servicing if they deviate from safety standards.

Requirements for premises according to SNiP

The installation of gas equipment in the bathroom is regulated by SNiP. Document 2.04.08-87 mentions a direct ban on the installation of heating devices in such buildings.

Studying the latest edition of the act SP 402.1325800.2018, you can see clause 5.6, which states that it is prohibited to install gas-using devices in bathrooms and bathrooms.

To protect the system from moisture, copper pipes are used.

Regardless of the features of the model, the equipment includes metal parts that are subject to oxidation when interacting with moisture. To protect the system from such phenomena, pipes made of copper or metal-polymer materials are used. If the rules are not followed, the unit will quickly wear out, increasing the likelihood of an explosion.

For speakers

Gas water heaters are potentially dangerous devices. Therefore, the room where the boiler will be installed must meet the strict fire safety requirements specified in SNiP and SP, as well as in the official recommendations of equipment suppliers.

The main regulatory restrictions include the following:

1. The ceiling height is from 2 m.
2. The room has a supply and exhaust or natural ventilation system, which ensures effective air replacement.
3. The total area of ​​the room is at least 12 square meters. m.
4. The room has a window or window that opens.

The bathroom must meet strict requirements.

Any non-residential buildings that meet the listed requirements are suitable for the boiler room. Technical restrictions vary based on regional specifications. Therefore, before installing the column, you should familiarize yourself with the regulations in force in your locality.

The regulations indicate that the equipment should be fixed at a distance of at least 25-30 cm from the ceiling. A distance of 80-120 cm is maintained between the floor covering and the body.

For gas boilers

Domestic gas boilers can be installed in those premises that meet the following requirements:

1. Area from 4 sq. m.
2. Entrance door from 80 cm wide.
3. Good lighting (0.3 sq.m of glazing per 10 cubic meters of space).
4. Ceilings from 2.5 m high.
5. Availability of a ground loop.
6. Access to cold water pipes.
7. The presence of a chimney, the cross-section of which corresponds to the performance of gas-using equipment.

Domestic gas boilers can be installed in rooms with an area of ​​4 square meters. m.

In addition, the surface of the walls in the boiler room must be leveled and plastered.

Is it possible to use liquefied gas

Complex bureaucratic procedures are eliminated in cases where liquefied (bottled) gas is used instead of natural gas. But for smooth installation it is necessary to choose the appropriate type of heater.

Burners for 2 types of fuel differ in different sizes of injector nozzles. In addition, equipment for liquefied gas is much less common on sale than for main gas.

The surface of the wall in the bathroom must be made of non-flammable and especially durable materials.

Features of kitchen renovation and design with a gas water heater

When planning the design and renovation of a kitchen with a gas heater, you need to take into account fire safety rules, ventilation and ergonomic requirements. Here are some important tips to help you design your workspace in the best possible way.

1. If you are equipping a kitchen from scratch, then it is advisable to think about the location of the gas water heater, layout and interior design even before renovating and purchasing furniture. Then you will have more room for maneuver and fewer problems. For example, you can move the speaker, change it to a more modern model or one that suits the future environment, improve the ventilation and chimney at the same time, adjust the color scheme of the interior to match the speaker, etc.
2. It is advisable to purchase a kitchen set to order, regardless of whether you plan to build the water heater into a cabinet or not. This will allow you to arrange your headset without errors and use every centimeter to your advantage.
3. Is it possible to install a suspended ceiling in a kitchen with a gas water heater? It is possible if the height of the room with the sheet installed is at least 2.25 m, and there remains a distance of at least 8 cm from the chimney opening to the ceiling. In this case, it is advisable to equip the chimney not with an aluminum corrugated pipe, which gets very hot, but with a sandwich chimney with thermal insulation layer. This way, the ceiling will not be damaged by heat (from combustion products going into the chimney) and will not itself become an obstacle to draft. If necessary, the chimney opening can be lowered slightly.
4. The walls in a kitchen with a gas water heater should not be decorated with wallpaper or plastic panels (at least near the water heater), as these materials can deteriorate/melt under the influence of heat. Ideally, the walls should simply be plastered, painted or finished with ceramic tiles (see photo).

Small kitchen with geyser and walls lined with ceramic tiles

1. In a kitchen with a gas water heater, a constant flow of fresh air is required (50-90 cubic meters per hour). This is necessary both for your safety and for the combustion stability of the unit. Therefore, when installing plastic windows, choose those that have a micro-ventilation function, that is, special fittings that allow you to open windows with micro-slots from 3 to 7 mm. Both in winter and in summer, kitchen windows with a gas water heater should be opened in this mode. If wooden windows are planned or have already been installed in the kitchen, then due to their natural micro-slits the issue of passive ventilation will be resolved by itself. The main thing is not to overdo it with waterproofing, seals and window insulation.
2. Supply ventilation valves embedded in the wall, for example, Kiv-125 or KPV-125, will help ensure air flow even more effectively. It is advisable to take care of their installation before repairs, so as not to spoil the finish.
3. In a kitchen with a gas water heater, both the supply and exhaust systems must work in a balanced manner. Therefore, it is necessary to invite professional ventilation specialists to check the chimney and ventilation duct. If necessary, they need to be put in order. And, of course, when arranging your kitchen, do not make the most serious and, unfortunately, common mistake - do not cover the ventilation duct with plasterboard boxes, wallpaper, or furniture.
4. And the last piece of advice - “in any unclear situation,” consult the gas service and act in accordance with the requirements of regulatory documents.

Selecting a gas device

A geyser is a device that is not purchased for a day or a month. Such a mechanism should serve you for years without causing any complaints.

To make your choice the most practical and effective, when choosing a geyser, pay attention to the following parameters:

Gas water heater performance

This most important criterion is responsible for the volume of water that the device can heat in one unit of time. As we mentioned, speakers are divided into low, medium and high power products.

Your choice depends on the following nuances:

• your personal needs;
• number of people living in the house;
• number of intake points: the mechanism can heat water not only for the bathroom, but also for the kitchen.

  A gas boiler can heat water for the kitchen and bathroom

If each aspect is higher, you need to give preference to a more powerful product.

Ignition type

The column can be ignited by matches (a lighter), a piezo that provides a spark, or automatic equipment.

Such a mechanism is both safer and more convenient.

Burner type

This nuance is very important, because some models require your intervention, which is not very practical. For example, a constant power burner requires manual adjustment. And the modulating power burner independently adjusts to frequently changing water pressure, guaranteeing a stable temperature level.

Removal of combustion products

At this point, you need to choose a turbocharged or chimney engine. In the first case, all waste is removed through the pipe simply into the street, in the second case - into the chimney.

There are two options for waste disposal: turbocharged or chimney method

Safety

Each device has several levels of security. Experts recommend purchasing a product with three degrees of protection for the bathroom. Such mechanisms have the following protective functions:

ionization sensor: self-blocking; if the flame goes out, the draft level will decrease or disappear altogether; overheating sensor: pay attention to the presence of a hydraulic safety valve that will protect the mechanism from overheating; combustion sensor: the system will automatically shut off the gas supply if the flame goes out and the ionization sensor does not work; draft sensor: protects the column from turning on or off in the absence of draft; water temperature sensors.

Each of the sensors is optional, but you must admit that with them you will be much calmer.

We have presented to you the most important five criteria that will determine the quality and durability of a new bathroom device. However, do not forget about the manufacturer, which is also important when choosing a speaker.

Valliant geyser

Among the world's manufacturers of such equipment, the following names enjoy the greatest confidence:

• Ariston;
• Termaxi;
• Vaillant;
• Beretta.

Gas water heaters produced by the presented manufacturers are considered the golden mean in the equipment market. Such companies offer a wide selection of devices at different prices, and most importantly, of high quality.

Pros and cons of installing a gas boiler in the bathroom

In order to evaluate the possibility of equipping a bathroom with a gas boiler, it is worth, among other things, studying all the positive aspects of this project. In a private house, especially if the premises are being redeveloped, the problem of placing new equipment is always very acute. That is why the option of using a heating boiler and a bathtub together in the bathroom is quite ambitious and has a number of advantages:

• The space inside the house is significantly saved;
• The number of pipelines is reduced;
• Hot water enters the bath faster, there is no large temperature loss;
• In other rooms there is no noise from operating equipment;
• A window will appear in the bathroom.

On the other hand, this arrangement also has a number of disadvantages that must be taken into account:

• The bathroom will have to be equipped with a separate ventilation system and constantly maintained in good condition;
• High humidity has a negative effect on equipment, especially electronic components;
• In the bathroom, in addition to the water supply pipes, additional heating pipes will be added, and this will take up a little more space.

How to get official permission

To obtain official permission to install a gas supply system in the bathroom, you can use the following methods:

1. Carrying out work on redevelopment of the building with adjustment of technical documents. If the Gas Service does not register heating appliances, you can change the status of the premises to “Converting a bathroom into a technical or household room” and submit a corresponding application to the BTI.
2. Connecting new equipment. If the project specifies registered heating equipment, installation difficulties will not arise.

Additional installation conditions

It must be remembered that placing gas appliances in the basements of apartment buildings is prohibited. When installing, you must follow the following rules from clause 7.3.8:

1. Gas units and heat generators are mounted on walls made of non-flammable or low-flammable materials.
2. Installation must be carried out so that the gaps between the device and the wall are at least 3 cm.
3. The finishing of walls near the heat generator must be made of fire-resistant materials.
4. The facing coating must extend beyond the unit body by no less than 10 cm.
5. For floor-standing equipment, additional fire safety measures must be taken. The floor surface where the heat generator is installed should be covered with special non-combustible materials. This area must be arranged so that it extends beyond the body of the gas appliance by at least 10 cm.

The official regulatory document on heating, ventilation devices and air conditioning 41 – 01–2003 in the section on heat supply systems provides rules for the installation and operation of gas appliances, as well as technical conditions for rooms where such equipment is connected.

In residential multi-storey buildings and various outbuildings, it is necessary to install heat generators with a sealed combustion chamber and automatic safety devices. Such devices stop the flow of gas when the power suddenly goes out, the protection circuits break down, when the burner malfunctions or when the pressure in the coolant decreases significantly. Sometimes an automatic emergency shutdown is necessary when there is poor smoke removal or other equipment malfunctions.

Appliances with heating output exceeding the specified norm must be installed in separate extensions. The total power of such equipment should not exceed one hundred kilowatts according to the standards.

The supply of oxygen for combustion processes must occur through the air duct. It must be placed on the street side for equipment with a sealed chamber. And for open-type heat generators, air is taken from the very room in which the installation was carried out. These requirements are listed in paragraph 6.2.4 of SNiP.

In the room where the heat generator with a sealed combustion chamber is located, it is necessary to equip general exchange ventilation, the calculation of which should be at least 1 exchange per hour.

Gas water heater

Gas heating equipment in the kitchen

Why was it made at all?

Old houses had their own characteristics that some people liked, while others struggled with them in every possible way, changing everything inside on their own. In Soviet apartments, especially five-story buildings, a common bathroom was initially built, which took up a minimum of space, but at the same time allowed you to enjoy the comfort of your own communications. Each house was designed taking into account certain rules that were considered necessary at that time.

The size of this window was approximately the same - 50x70 or 60x40 cm, depending on the dimensions of the wall. The presence of an additional product was due to several factors.

Protection of the premises in the event of a blast wave from a gas water heater. The designers assured that the presence of a window would help minimize the impact on the wall, which would make the damage minimal. In fact, this is not so, and if a gas water heater explodes, a wall with or without a window will collapse in the same way.

Ventilation in the toilet and bathroom. This function is not the main one, since most of the structures were solid and could not help in ventilating the bathroom and creating an additional draft in the apartment.

Possibility of saving electricity. In sunlight during the daytime, it was possible not to use a light bulb in the bathroom, since the room was quite well illuminated by the sun's rays. By the time the “Khrushchev” buildings were built, there was often no light in the houses, and the presence of at least a small light source in each of the rooms was a great advantage, but this reason was also not the main reason for installing a window between the bathroom and the kitchen.

The main task of erecting an additional window structure in Soviet times was to combat the tuberculosis epidemic, which was spreading at a rapid pace, and it was necessary to solve the problem by any possible means. Thanks to sunlight, it became possible to disinfect the bathroom, which had the most favorable environment for the proliferation of microorganisms, due to the warm and humid environment. Even with a minimum of two hours of light exposure throughout the day, it was possible to significantly improve the morbidity situation thanks to the prevention of housing in each apartment.

We invite you to familiarize yourself with Finishing a bathroom with panels in a wooden house In modern realities, there is no longer a need to place a window between the bathroom and the kitchen, since the tuberculosis epidemic is already a thing of the past; it is successfully combated with medications. Modern houses are built without additional structures in the walls; a good hood, which draws out all excess moisture, helps to achieve cleanliness and comfort in the bathroom. Old apartments that still have windows between the bathroom and kitchen can be remodeled depending on personal wishes and needs. Those who consider the presence of such a product appropriate simply replace the old window with a plastic one.

During the construction of Khrushchev houses, the main plan was to quickly provide housing to the population, in particular to the working class. The emphasis was not on building comfortable and spacious mansions, but on housing that was completely suitable for living. Under these conditions, the well-known 438 and 480 series of apartment buildings were born, which were distinguished by a small bathroom and a small kitchen.

Another reason for the creation of the notorious window was the frequent power outages at that time. In the Khrushchev-era layout, the window between the bathroom and the kitchen goes directly onto the main kitchen window. As a result, in those days, even when the power was turned off, a working person could easily, albeit in poor lighting, take a shower or go to the toilet.

Show or hide

Of course, we all want to make the bathroom the most comfortable and aesthetically pleasing room possible, because this is a territory not only of hygiene, but also of relaxation. Large-sized gas equipment that is not always attractive in appearance usually does not fit into our ideas of a beautiful and comfortable bathroom, although now you can find speakers on sale that can become a decoration for the bathroom.

It would seem that the most obvious solution is to hide the gas water heater inside the wall, but all standards and safety requirements strictly prohibit this. Therefore, if you do not want to leave your instantaneous water heater in plain sight, you can hide it in a plasterboard niche or in a closet.
