To ensure functionality and comfort, it is essential to comprehend the dimensions and standards when planning a bathroom renovation or building project. The SNiP (Sanitary Norms and Rules) regulate these standards in Russia and offer comprehensive guidelines regarding the minimum sizes and specifications for bathrooms in residential buildings.
Respecting SNiP standards is crucial for establishing a secure and welcoming environment as well as for regulatory compliance. In order to maximize the use of available space, these regulations consider a number of variables, including the positioning of fixtures, door openings, and general layout.
Knowing these measurements will help you make wise decisions whether you are remodeling an old bathroom or designing a new one. The SNiP guidelines cover every important detail to make sure your bathroom is both functional and comfortable, from the minimum space required for a toilet to the suggested height for sinks and showers.
We’ll discuss the important measurements as laid out by SNiP in this post, giving you a clear idea of how to organize your bathroom. Armed with these insights, you can start building or renovating your bathroom with confidence, knowing that it will fulfill all the requirements.
| Type of Bathroom | Minimum Dimensions |
| Combined Bathroom | 3.8 m² |
| Separate Bathroom | 1.2 m² (toilet), 1.5 m² (shower) |
| Accessible Bathroom | 2.2 m² |
Dimensions – SNiP and DIN
The dimensions of a bathroom for residential premises are clearly defined by the current technical regulations, which are reflected in SNiP and DIN 18022:
- minimum floor/ceiling height – 2500 mm;
- depth – not less than 1200 mm;
- in the attic, the distance from the toilet to the roof slope is 1050 mm;
- minimum width of the bathroom – 800 mm.
Doors must only open outward, and exits may only be made from living rooms, kitchens, and hallways; leaving the restroom or bathroom is not permitted. In the corridor at the exit, the ceiling height should be at least 2100 mm.
Additionally, SNiP governs the installation of plumbing fixtures in bathrooms, as well as the standard sizes of bathrooms and bathrooms with combined toilets and bathtubs:
- there must be at least 700 mm of free space in front of the bathtub and shower, and 600 mm of free space in front of the toilet;
- the bidet is installed 250 mm from the toilet, unless otherwise provided by the model;
- there should be 250 mm of free space on the sides of the plumbing point.
Typical bathrooms in residential buildings
Standard apartment buildings typically have toilets that are 1200 * 800 mm, 1500 * 800 mm, or, with an upgraded layout, 100 * 1500 mm, which can fit a narrow washing machine or sink.
The average bathroom’s dimensions are 1650–2000 * 1200–2500 m. combined space of 3.3 and 3.8 m2 in Khrushchev.
Toilets in new economy class buildings are already somewhat larger, starting at 4 m2, and rooms in better series of homes are 5–6 m2. Rarely is the space in a luxury apartment less than 7 m^2. In a private home, a bathroom should ideally measure 9 square meters. With this space, you can set up a whole haven of calm.
Minimal bathroom
The smallest latrines have a diameter of 1.8–2.0 m.Kv. found in compact housing. However, even these spaces can be furnished comfortably.
Naturally, the bathtub will have to go in favor of a cheap cabin or panel, but even a narrow washing machine can fit if plumbing fixtures are positioned correctly.
A small curved bathtub can already be placed in a combined room with a small area of 2.2 m.kv. When there are young people living in the home, a shower cabin is a good idea, but baths are a need for elderly and young children.
How to choose a size
Many people get tired of their ordinary small bathrooms and start dreaming of a large space where they don’t have to save every centimeter when they can independently set the size of the bathroom without any space restrictions. A large bathroom is a complete waste, so let’s schedule a reservation now. Here, you need to find a compromise.
The ergonomic laws state that a shower stall needs to be 1.7–2.5 m³, a comfortable bath needs to be 2.7–3.5 sq. m³, a toilet needs to be 1.2–1.8 m³, and a sink needs to be about 1 m. Therefore, 7-9 m.kv is the ideal restroom area for a family of 4-6 people. It is ideal if the space is rectangular, with the bathroom measuring 2.5 meters in width and 3.5 meters in length.
In order to properly plan a bathroom, it helps to know:
- height of a standard bathtub with legs – 640 mm, without – 480-510 mm, bath sizes 750-800×1600 mm, 750-800×1700 mm, corner models – 1500×1500 mm and 1600×1600 mm;
- shower cabins – 800×800, 900×900 and 1000×1000 mm; for small rooms it is recommended to choose a shower panel with a tray;
- To make it easy to reach, the heated towel rail should be 500-700 mm away from the bath or shower;
- depending on the model, toilet sizes may differ – 440×650, 400×600, 360×650;
- bidet – 370×540 and 400×600 mm;
- The minimum washbasin size is about 400 mm wide.
It is important to know

Therefore, the bathroom should have a minimum area of 2.3 square meters. m, toilets with washbasins starting at 1.6 m.kv., and 1.2 m without washbasins are permitted. wheelchair users, the bathroom’s dimensions are 1800 mm in depth and 1650 mm in width.
