Gas units are not intended for location in enclosed spaces. It is almost impossible to obtain official approval for installation. Why do gas workers refuse, what motivates the ban, what documents are they referring to and what to do in this case? Find out the answers to these questions from this article.
- 2 Regulatory standards
- 3 SNiP regulations, comments on standards
3.1 What requirements must a bathroom meet?
Is it possible to install a gas boiler in a bathroom?
In Soviet times, this arrangement of speakers was practiced in five-story buildings. Technical standards in the USSR allowed this. This arrangement made sense - while bathing, a person could regulate the heating temperature of the water. In addition, bulky equipment did not spoil the interior of the kitchen.
Modern standards prohibit installing or hanging boilers in bathrooms. The main reason is the large number of cases of carbon monoxide poisoning. There is no direct ban, but standards for compliance of premises have been stated. The bathroom and toilet do not meet these requirements. Therefore, if it is possible to place the device in another room, give up the idea of unauthorized mounting of the device.
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.

Regulatory Standards
The story of obtaining documentary consent to install a gas boiler in a bathroom is complicated by confusion with permitting papers. Current regulations do not contain specific information about whether it is feasible to place the device in a bathroom.
Gas company employees refuse, citing SNiP 2-04 . The ban is clearly regulated there.
However, according to the Decree of the State Construction Committee, these documents have lost their legal force. The result is that difficulties and misunderstandings arise. To get approval from gas workers, you need to collect a bunch of papers. Unauthorized connection is fraught with big problems.
What is more profitable to buy in terms of price?
To determine which heater is cheaper, you need to consider several points:
- The price of the device itself. Depending on the parameters of the model, it will vary greatly.
- Cost of installation work. Installing a gas heater is much more expensive than installing a boiler.
- Energy costs. For our country, the use of natural gas is more accessible and cheaper than the consumption of electricity.
- Maintenance costs. Both types of appliances need to be cleaned periodically.
Most often, the price of a geyser, taking into account the cost of installation, turns out to be more expensive than the price of a boiler, but energy costs are higher for a boiler, since gas in our country is quite cheap.
SNiP regulations, comments on standards
The procedure for installing equipment in residential spaces is regulated by SNiP. The document says: it is not recommended to hang a gas boiler in bathrooms and toilets - provision 2-04 SNiP.
The paradox is that this standard is being canceled by another document - Gosstroy Resolution No. 163. Together with it, the Gas Distribution Code SP 62-13330 came into force. There is no information about the ban at all. The document defines the general conditions that apply to the premises where the equipment is planned to be installed. Let us consider them in more detail in relation to a specific space.
What requirements must a bathroom meet?
Standard placement principles:
- useful area - less than 7 m, total - from 9 - for gas equipment with an open burner. For closed models - from 8 squares;
- there is a supply and exhaust;
- window - its parameters depend on the energy consumed by the equipment. If we are talking about an apartment building, the standard requirement is an opening of no more than 1.7 square meters;
- Leave a space of 2-3 centimeters between the door and the frame. Experts recommend installing a ventilation grill into this space at the bottom of the door;
- the distance from the wall opposite is 1 meter - this is necessary for uniform circulation of air flow.
From the listed nuances it is clear that locating the boiler in the toilet is impossible precisely because of the inadequacy of the room - a small square area, no natural light.
Installation: recommendations and diagrams, main stages of chimney installation
Chimney installation is divided into several stages - preparatory work, installation itself, then connection, startup and, if necessary, debugging of the entire system.
General requirements
When several heat-generating installations are combined, each of them creates its own chimney. In exceptional cases, a tie-in to a common chimney well is allowed, but a difference in height of at least one meter must be maintained.
First, the chimney parameters are designed and calculated, which are based on the recommendations of gas boiler manufacturers.
When summing up the calculated result, the internal cross-section of the pipe cannot be less than the diameter of the boiler outlet pipe. And according to testing according to NPB-98 (fire safety standards), the initial speed of the natural gas flow should be 6-10 m/sec. And besides, the cross-section of such a channel must correspond to the overall performance of the unit (8 cm2 per 1 kW of power).
Installation steps
Chimneys for gas boilers are mounted outside (attached system) and inside the building. The simplest is the installation of the outer pipe.
Installation of an external chimneySource astroyresurs.ru
Installing a chimney on a wall-mounted boiler is done as follows:
- A hole is cut in the wall. Then a piece of pipe is inserted into it.
- The vertical riser is assembled.
- The joints are sealed with a fireproof mixture.
- Fixed with wall brackets.
- An umbrella protecting from precipitation is fixed on top.
- An anti-corrosion coating is applied if the pipe is made of metal.
Proper installation of the chimney guarantees its impermeability, good draft, and does not allow soot to accumulate. Installation performed by specialists will significantly reduce the cost of maintaining this system.
When constructing an opening for a pipe in the roof of a house, special boxes with aprons are used. In this case, the design as a whole is influenced by such factors as:
- The material from which the pipe is made.
- External design of the chimney.
- Type of roof covering.
The main factor influencing the choice of design is the temperature of the gas that passes through the pipe. At the same time, according to standards, the distance between the chimney pipe and combustible materials must be at least 150 mm. The most advanced assembly system is considered to be in segments, where all elements are assembled using the cold forming method.
What is the penalty for installing a gas boiler in a bathroom?
The reasons why it is prohibited to install gas equipment seem unfounded to many. But the punishment for unauthorized installation is quite serious. Self-installation means, at a minimum, penalties and forced removal.
Unscrupulous users circumvent the law. They order design papers in such a way that the premises are listed as a boiler room. The bathroom, accordingly, is excluded from the project plan. The gas unit is installed and connected. After this, all plumbing returns to its place. The apartment owner happily forgets about troubles and problems with documents.
A year later, when gas workers check the operation of the boiler, violations will come to light. The employee will draw up a report and issue a fine, the minimum amount of which is 45,000 rubles.
Legal information! If the illegal installation of gas equipment caused damage to someone else’s property or resulted in the loss of human health or life, criminal liability and a real sentence of 2 to 5 years arise.
Advice! If you still decide to install a boiler in the toilet, do it legally. Since regulatory documents do not strictly prohibit installation, proceed as follows:
- submit an application to the head of the gas organization with a request to install a boiler in the bathroom or toilet;
- motivate your demand, formulate the reasons why you insist on installation in this location;
- attach supporting documents;
- If the arguments were not enough, write a statement of claim to the court. There is a chance that the decision will be made in favor of the plaintiff.

Connecting a ceramic chimney
Ceramic chimneys themselves are practically eternal, but since this is a rather fragile material, you need to clearly understand how to correctly connect (docking) the metal part of the chimney and the ceramic one.
Docking can only be done in two ways:
For smoke - a metal pipe is inserted into a ceramic
It is important to remember here that the outer diameter of the metal pipe should be smaller than that of the ceramic one. Since the thermal expansion of metal is much greater than that of ceramics, otherwise the steel pipe, when heated, will simply rupture the ceramic one.
For condensate, a metal pipe is placed over a ceramic pipe.
For both methods, specialists use special adapters, which, on one side, are equipped with a gasket for contact with a metal pipe, and on the other, which contacts directly with the chimney, are wrapped in a ceramic cord.
The joining should be carried out through a single-wall pipe - it has a higher heat transfer coefficient. This means that the smoke will have time to cool down a little by the time it reaches the adapter, which ultimately extends the service life of all materials.
Which boiler can be installed in a bathroom?
If you decide to install a boiler in a toilet, choose the equipment correctly. The Code of Practice dated January 2003 does not prohibit the installation of gas units in the bathrooms of apartment buildings that are not connected to an individual or central heating system. The main condition is the closed type of the boiler chamber.
Advantages of gas heating
Everyone knows that residents of apartment buildings in the city pay much more for heating their homes than people living in country houses. What is this connected with?
First of all, with the fact that prices for heating and hot water are too high, and sometimes simply unreasonably high. At the same time, the temperature in the apartment often does not correspond to the norm, so there cannot be any pleasure from such a stay.
To solve the problem, some townspeople install an autonomous heating system with a gas boiler, the advantages of which are obvious:
- Autonomy - independence from hot water suppliers. And gas shortages are extremely rare.
- Creating a comfortable level of heat in rooms with the ability to regulate it.
- In addition to heating the home, it is possible to use hot water.
- Significant financial savings when paying for housing and communal services.
- Creating coziness and comfort regardless of the beginning of the heating season - at any time, in cold weather, in autumn and spring, you can independently turn on the heating of the apartment.
Official conditions for the location of gas water heaters in the bathroom
Why do many people want to hang a boiler in the bathroom? This location has a number of advantages:
- compactness;
- the device does not spoil the interior of the kitchen, does not take up additional space;
- hot water flows directly to its destination - to the shower and sink.
Installation rules:
- redesign the premises;
- record changes in technical documentation;
- register the boiler with the gas company. To do this, reformat the room in the BTI - give it the status of a storage room;
- Call a specialist - a representative of the gas service and connect the equipment.
Types of equipment
There are two types of boilers:
- storage water heater;
- flow boiler.
Storage type equipment is a boiler that is similar to a boiler. The device is equipped with a reservoir of various capacities. Storage elements are placed inside the tank. As hot water is consumed from the tank, the tank is filled with tap water. The automatic control panel allows you to regulate the heating temperature, prevents overheating and boiling of the liquid in the tank. Such boilers are produced in two modifications:
- hanging - they are mounted on the wall;
- stationary - installed on the floor.
A flow-through boiler has a more complex design. The column heats up quickly thanks to the heat exchanger. The liquid will become hot in 7-10 minutes. The main advantages of flow-through boilers:
- efficiency;
- ease of operation;
- reliability of the unit.
In addition, such devices have an automatic ignition system. This guarantees the safety of using the equipment - gas vapors are burned in full.
As practice shows, flow-type boilers are more popular. The device has small parameters, it is convenient to place it in small rooms. At the same time, the boiler’s power is enough for a family of 5 people.
Selecting panels for finishing
To make PVC panels look beautiful and last a very long time, you need to choose the right materials. Today in stores there are many options for panels that differ in color, width, thickness and plastic density.
First of all, you need to evaluate the evenness of the panels. There should be no “waves” on the surface of the material, because after using such panels the walls will look ugly and cheap.
An important parameter is the strength of the material, or rather its ability to break when bent and be pierced by sharp objects that are found in any bathroom. Typically, panels with dimensions of 2700x250x10 mm are used to decorate a bathroom.
Rules for choosing quality panels:
- When choosing, look at the number of stiffeners. The strength of the panels directly depends on their number, therefore, the more ribs, the better;
- The thickness of the material must be at least 1 centimeter, and the thickness of the coating must be from 0.5 millimeters;
- In the store you need to take the PVC panel in your hands and look at the condition of the stiffeners. If they are deformed, this means that the material is of poor quality and was not stored in proper conditions. Such panels will not last long;
- Also carefully examine the color of the panels. If the pattern is blurred or the panels of the same color are not monochromatic, then such a finish will not look beautiful, and this does not indicate high quality;
- Joint density. This can also be checked directly in the store by connecting two panels. If they are of high quality, then the seams will be almost invisible;
- The dimensions of finishing materials are usually indicated on the label, but it is better to double-check. If the values do not match, then the reason is either an unfortunate mistake by the manufacturer, or that they are trying to sell you a fake;
Before going to a hardware store, you need to take all measurements and calculate how many panels you will need. If you take too much material, then it will be a waste of money, and if you take too little, then you will have to run to the store again, where there may already be another batch with a slightly different shade.
