15 ways to create a bright space |

Basement bathroom ideas can help turn your unused lower level into some of the most desirable living space in your home: an in-law suite, guest quarters, or a basement theater room that doesn't require pausing the film every time someone needs to run upstairs for a restroom break.

Aside from the practical considerations, bathroom ideas in a basement are also a chance to add style and even luxury to your home. Because it's off of the main floors of your house, you can step outside the style constrictions of the rest of your decor. And if you have the room, fun add-ons like a home sauna or rainfall shower can make the room the best bathroom in the house.

Basement bathroom ideas

By necessity, any basement ideas you search might be compromised by space restrictions more than any rooms at ground floor level and above will be, with the exception of the attic. For this reason, basement bathroom ideas need to include clever, space smart options that can feel luxurious and look aesthetically pleasing, too.

1. Let in light where you can

(Image credit: Erick Zumwalt, Phil Ruhl)

Depending on how far below grade your basement sits, you may not have room in your basement bathroom for a full-size window. But any natural light is better than none, so get creative with the types of windows that will work in your space.

Clerestory-style windows, like the one in this bathroom by California-based design duo Erick Zumwalt and Phil Ruhl, sit high up on the wall, providing natural light without the need for a full-length window. Plus, the position means you won't have to deal with window treatments or privacy concerns. 

2. Warm it up

(Image credit: Samantha Burkhart)

Basements can tend to feel a bit cold and industrial thanks to their subterranean location. One way to cozy-up your basement bathroom and make it feel like a part of your home? Incorporate furniture pieces, like the warm-toned wooden dresser and tufted chair in the Montana bathroom of celebrity stylist Samantha Burkhart.

If you have a basement bedroom, too, choose complementary furniture to tie the spaces together and make it feel like its own suite. 

3. Draw the eye up

Unless you've hit the basement jackpot, there's a good chance your basement bathroom has standard height ceilings of eight or nine feet, possibly even less if you live in an older home or an area where building codes okay lower ceilings.

'Painting the crown molding black in this showhouse bathroom originally got some pushback from the builder; she had originally painted it gray and was afraid to go darker. The gray was meh and didn't help the space out at all!' says designer Leah Atkins . 

'Painting the trim black and adding a collage wall really made this basement bathroom feel larger. Adding a red and blue oriental rug to ground the space was the homey finishing touch it needed.'

4. Add wallpaper

Just because it's a basement bathroom doesn't mean you should scrimp on the details. like this space by House of Jade Interiors proves. From the checkerboard floors, to the marble walls and the built-in shower nooks, there's a lot to love about this chic space. But it's the wallpaper that brings the wow factor. 

Choosing a rich color and traditional pattern adds gravitas and sophistication to this otherwise monotone space, and warms up the cool palette. 

5. Add a luxurious shower

Oftentimes, the basement serves as a home's guest suite, so why not add a high-end  feature that'll make your nearest and dearest feel like they're at a posh hotel? The designers at Classic Homeworks in Denver made this basement bathroom one of the home's most luxurious spots thanks to a glass-walled shower. 

6. Tile a wetroom

Is there anything more luxurious than a wetroom? Pair a flush shower tray with matte or slip-resistant tiles with a realistic marble-effect to create the ultimate showering experience.  

This bathroom goes one step further and includes a freestanding bath with ceiling speakers so you can sit back and relax away from it all. 

7. Embrace unusual basement spaces for a unique bathroom

To make the most of your basement, you'll have to embrace its quirks. If your project deals with a sloping site, or if you’re wrestling with low ceilings in the basement, embracing the individual qualities of the space could make your new bathroom even more special. 

A change in floor level and an innovative shower recess – with built-in storage – design makes the most of the space available and creates a bespoke finish in this stunning, modern bathroom. 

8. Remember good lighting is key

When planning your lighting for a bathroom always remember the three essentials: task, ambient and accent lighting. 

Glamour lights in vanity mirrors or strategically placed pendant lights are great to illuminate jobs like putting make-up on or shaving while recessed downlights in the ceiling can take care of general (ambient) lighting.  

Accent lighting – such as LED strips or wall sconces – adds that finishing touch to any space, highlighting special objects or pictures. 

9. Create a light well 

(Image credit: Maison Vanentina)

Where possible, adding a glazed light well to the outside of your bathroom will always be worth the effort. 

Basement bathrooms by their very nature struggle with natural light and anything you can do to fight feeling cramped or claustrophobic will get you one step closer to your dream room. 

10. Reference natural elements

(Image credit: Porcelain Superstone)

Basement bathrooms suffering from a lack of natural light can feel a bit disconnected from the outside world so introducing links to the great outdoors where you can is essential. 

Wooden vanity units, natural stone tiles and even a natural clay wall finish are all wonderful ways to connect a bathroom basement to nature. 

11. Install walk-on roof lights

(Image credit: Mereway Bathrooms)

Consider installing walk-on rooflights above the basement as they are a great way to ensure natural light will be able to permeate the room from spaces above.  

It's an excellent small basement bathroom idea for creating a space that feels more expansive, and also works wells for spaces that are entirely subterranean. Do keep privacy in mind though – think carefully about their position and ensure the glass is opaque.

12. Make the bath the star of the show

(Image credit: Paul Raeside)

Freestanding baths are without a doubt one of the most beautiful elements to include when designing a new bathroom. 

Placing the tub in the middle of the floor – and adding LED wall panels as in this example – not only provides a luxurious finish inspired by boutique hotels, but also makes bath time fun for young children. 

Although be sure to choose a suitable flooring for the splash zone.

13. Get creative with lighting

(Image credit: Matki One)

Planning in basement lighting ideas with your architect or electrician in advance of your basement project can inspire some wonderful results. For instance, recessing an LED strip within a shadow gap before adding the finishing touches can create a beautiful wash of light, as this bathroom goes to show.  

14. Contrast light and dark

(Image credit: Porcelain Superstore)

Matching a pale wall tile with an on-trend bold wall and industrial-style matte black fixtures is a sure-fire way to make a big impact. Tile floors are also one of the best basement flooring ideas because they're resistant to moisture and dampness.

15. Create a view with a feature wall

This majestic monochrome bathroom is a masterclass in elegance and timeless style. Keep your fixtures simple and splurge on a mural or statement wallpaper so your new space in the basement takes you to another place. 

How much does it cost to put a bathroom in the basement? 

Let's talk money, how much does it actually cost to put a bathroom in the basement? 

'The answer is — it depends,' says James Hockley, managing director of Trace Basement Systems . 'In respect of the waterproofing, for a full conversion of a responsibly-sized single room from a reputable company providing the worthwhile guarantees could be in the region of £10-£15,000 ($12-19,000). '

Add on top of the costs of a normal new bathroom, which can range anywhere from £3,000 up to £9,000+, depending on the quality of finish and professional installation costs. 

How do I plumb in a new basement bathroom?

There are also logistics to consider, like how you go about plumbing a new basement bathroom.

Plumbing is one of the most challenging aspects of creating a bathroom in a basement so positioning the layout close to existing plumbing above will reduce costs a little as extending the water lines to create new hot and cold water taps is naturally cheaper than routing new ones. 

'Pay particular attention to mechanical ventilation as basement bathrooms do not typically include windows and the structure may effectively be vapor tight as a result of the installed waterproofing,' explains James Hockley. 

'Therefore you must take provision to adequately deal with vapor production or otherwise suffer condensation issues.'

Do you need a special toilet for a basement?

Yes, you might need a different or special toilet for a basement bathroom.

While installing a normal toilet is feasible in some basement bathrooms, if your space is positioned below the sewer lines an upflush (also known as a macerating) toilet would be more suitable. 

Where a normal toilet flows down towards the soil stack, upflush units discharge into a tank (which can be concealed behind drywall), where waste is ground up before being piped towards the stack, meaning these toilets can be installed pretty much anywhere. 

How should I decorate a basement bathroom? 

Once the structure and waterproofing has been completed, it's time to think about how to decorate a basement bathroom.

The design can be similar to any other bathrooms, although you may want to compensate using various tricks of the trade for the lack of natural light, such as including large mirrors, rooflights or even small courtyards outside the basement. 

How do I light a basement bathroom? 

Rooms underground are going to be dark, so it's important to think about how to light a basement bathroom.

'Compensate for natural light by using multiple layers of light in your bathroom,' advises Sian Parsons, associate designer at John Cullen Lighting. 

'Use downlights to provide ambient lighting and wall lights either side of a mirror for task lighting. Look at building your layers with a mid level of light such as downlights in niches, uplights behind a bath or floor washers — by putting the layers together you get a good feeling of general light.'

And the last room is the gym in the basement. This is the only place that is not economic, but rather entertaining. Under it allotted 16.1 square meters. m. this is quite enough to accommodate several simulators, wall bars and a shower room. The lighting in the gym should be bright so that the eyes do not get tired quickly.

Space planning

As soon as the tenant climbs the stairs, he will enter the hall (7 sq. m.) on the first floor. From it, through an opening in the wall, you can get into the hallway (6.7 sq. M.). From the living room and from the hall you can go to the kitchen, the area of ​​​​which is 19.6 sq. m. On the ground floor there is also a shared bathroom and a vestibule (2.9 sq. m.). The guest bedroom on the ground floor is 33.6 sq. m., designed for temporary residence of two people.

plan of the 1st floor of the house

The second floor of the house has a standard layout, only from the hall you can get into each of the five rooms. So, the first is an office on the second floor. It is located at some distance from the rest of the rooms so that extraneous sounds and noise are not heard. From the office you can go to a long balcony overlooking the site. nine0004

The two bedrooms on the second floor are 13.9 sq. m. and 14.0 sq. m., these rooms are located nearby. The third room can be arranged as planned by the owners, it is advisable to arrange a nursery or a library there. The size of this room is 15 sq. m., it has a small feature - the bearing wall, which overlooks the backyard, is a huge window. This allows in the daytime not to use any additional artificial light sources at all. nine0004

And the last room is the bathroom (7.8 sqm). This room will be enough to accommodate not only the bath, but also the shower, sink and other plumbing equipment.

Additional information

The layout of the house with a basement provides for a family of six people to live all year round. Total area - 251.8 sq. m. Of which the living area is 106.33 sq. m. m.

Characteristics:

To build such a structure, the plot (at least) must have the following dimensions: 10.2 x 12.3 m.

construction of country houses. A large number of advantages, coupled with the requirements, will ultimately provide a large free space that can be arranged as you wish. There are enough rooms for technical rooms, and for the implementation of any design idea. nine0004

Project of a house with a garage in the basement

For a modern house, the main thing now is to be compact, but at the same time convenient and comfortable, and, of course, to have some kind of zest. The garage in the basement of the house is just such a feature that can change the perception of the entire building as a whole. Such a building is suitable for a family of no more than 7 people, all year round.

Project of a modern cottage with a garage and a high-tech basement

This layout of the house with a basement and a garage provides for traditional architecture. Spacious and bright rooms will prevail. One of the main advantages will also be a complex consisting of a bathhouse, a sauna and a relaxation room. The owners of the house will be pleased with the presence of a guest room and an office for work.

The layout of the house, built in high-tech style

So, as soon as the tenant enters the house, he enters the hall, the size of which is 9.5 square meters. m. The entrance is through double doors, which are equipped with safety chambers. Next comes the living room, its area is 39.5 sq. m., this space can also be used to good use. For example, to embody a design idea or install a sofa for relaxation.

In order to isolate extraneous sounds and noise that can be heard from rooms located nearby, the door and walls are upholstered with insulation. It is able to isolate not only sound, but also heat. It is for this reason that comfort will reign in such a house.

ground floor plan with garage

The kitchen-dining room (12 sqm) is accessed through the hall. It provides for the presence of a zone for eating food, as well as a zone for its preparation. Between themselves, they will be separated by a folding partition in style and design that matches the surrounding interior. The first floor also implies the presence of a shared bathroom, the area of ​​​​which is 3.5 square meters. m.

modern hi-tech house layout with semi-circular terrace

From the ground floor, stairs lead to the upper or lower floors. The ground floor includes a hall with an area of ​​4 sq. m. From it you can go to two storage rooms with a size of 12 square meters. m. each, into the boiler room (12 sq. m.). From the hall you can get to the garage (27.0 sq.m.), and from it to another technical room. There is also a bath complex, which is very convenient for small areas where it is almost impossible to place a separate bath. nine0004

plan of the second floor of the house with a large balcony

It is worth noting that before making a decision on the construction of a bath complex, it is necessary to take care of heating. As a rule, a modern boiler room requires a lot of free space. In order for autonomous heating of the house to be really effective, one cannot do without such components as:

Garage in the basement: advantages and disadvantages

Another feature of the project is that the basement is equipped with an attached garage. Its area is 27.0 sq. m. It will be possible to get into it exclusively from the street, along a ladder specially built for this purpose. Quite often there are similar projects involving the construction of a garage in the basement.

Previously, such an extension was found to be inexpedient, since car smells constantly penetrated into the house, thereby creating a certain discomfort. However, this layout of the house with a basement and a garage in it includes a serious and well-thought-out ventilation system, so absolutely no extraneous “incense” can enter the living quarters. nine0003 Another reason why a garage is often abandoned in such a place is the fact that it is necessary to overcome a large angle of inclination to get into the garage. In summer it is not scary, but in winter it can turn into a big danger. However, this issue was also resolved. To do this, you need to use a special ladder, equipped with small protrusions from the edges.

The machine is thus completely safe from tilting. With the use of a boiler room (for a bath complex), it is possible to provide an inlet line with a heating device. Then, even in the cold season, ice will not form in this place, snow will not accumulate, which means that movement will be safe. nine0004

Garage in the basement

The second floor was built without any special features or "highlights". Everything is as simple and comfortable as possible: two bedrooms with a size of 21 sq. m., 12 sq. m. There is an office (32 sq. m.), as well as a bathroom with an area of ​​6.1 sq. m. m adjoining one of the bedrooms. From the office and bedroom you can get to the balcony. The entire space of the second floor should be bright and light, as if filled with air.

If the first two floors are intended for active activity, for daytime pastime, then when you go up, you get a feeling of calmness and silence. It is this atmosphere that allows each family member to relax and unwind after a busy and hard day at work. nine0004

General part

Construction of the building will be made of insulated bricks. The foundation of the flood type goes along a monolithic slab. Insulated bricks are also used as a material for external walls, and reinforced concrete slabs are used for ceilings. Roof made of wooden rafters. The roof is ventilated, made of tiles. For the facade, plaster based on mineral substances and insulation is used.

This layout of the house is very comfortable and functional. Such a house is suitable for a large number of people and each of them will find a place and something to do. Unusually in the layout, even a clear separation of boundaries. The first floors are working, and the second is exclusively for recreation. The garage in the basement and several bathrooms are all trifles, but it is precisely because of them that the general sociability of the entire structure is formed. nine0004

Back to the top

A house with a basement for a large family

A house that will suit almost every modern person. It consists of two floors, suitable for a family of four all year round.

The entrance to the house begins under a small canopy. This is necessary so that on a hot day you can hide from the scorching rays of the sun. Further stairs and entrance to the house. From the very beginning, the tenant enters the entrance hall, whose area is 2.3 square meters. m. This is enough to accommodate a small closet or just a shoe rack. nine0004

From the entrance hall, a door leads to the hall, which measures 5.8 square meters. m. From it you can get into a small bathroom (3.3 sq. m.), and a shared bathroom (1.5 sq. m.), which is located opposite the bathroom.

layout of the 1st floor of the house

From the hall you can go to the kitchen (12.4 sq.m.) and living room (14 sq.m.). Here is hidden the first feature of the entire internal layout of the house. The passage will be in the form of an arch (its appearance can be chosen in accordance with the surrounding interior). nine0004

The second feature is that the living room and kitchen are a single space, which will be divided by a large two-sided wardrobe. The kitchen will have all the necessary elements for cooking, as well as its use. The living room, like any other, has items for an interesting and exciting pastime (set-top boxes, computer, TV). In the living room on one of the main load-bearing walls there is a huge window in the entire height of a person. This will make the lighting in the daytime much better. nine0004

In addition, the first floor includes two bedrooms. They are for the residence of family members, their size, respectively, is 15.6 square meters. m., 16.3 sq. m. A terrace is attached to the house, on which it will be possible to arrange a recreation area, place a deck chair there and put a table. Its size is 1.7 square meters. m., and access to it can be done from the street or from the kitchen.

Bath complex in the basement

Before going to the basement, you need to pay attention to the stairs to the basement. Unlike standard layouts, it is of a screw type. This is necessary in order to save space and complement the interior of maximalism. This staircase looks beautiful and unusual. After descending along it, the tenant enters the hall (12 sq. m.), from which you can go to the room (14.4 sq. m.), the owners will be able to equip it at will. It is recommended to place a library or workshop in this place. nine0004

Next comes the billiard room (26.8 sqm). This large space is reserved for a small refrigerator, one table and several sofas. In this place and the previous room, it is recommended to create the most favorable lighting. You should not choose white or yellow for this, as the eyes can quickly get tired from multi-colored lighting.

plan of the basement floor of the house with a sauna

From the hall you can go to the dressing room (6.5 sq. m.), from which there is access to a shared bathroom (1.7 sq. m.). Further from the locker room there is a passage to the washing room (4.1 sq. m.), from there to the sauna (4.1 sq. m.). Such a complex will not require bright lighting, most likely, on the contrary, a little dim. For complete comfort, it is necessary to carry out not only work to improve the ventilation system, but also take care of heating, as well as water supply. nine0004

And the last room on this floor is the boiler room (7.9 sq.m.). This space is used to install heating boilers, gas water heaters, etc.

Benefits of this plan

The presence of a sauna in the basement provides certain advantages. One of them is that you do not need to go anywhere, everything is in your own home. Another - next to the sauna, you can place a room in which engineering systems will be located. And the last - you can do the construction of not only a sauna, but also a shower room and a rest room. Be sure to take into account that competent waterproofing must be present. nine0004

House with a basement - convenient and comfortable

Another plus is the presence of a boiler room. It will contain not only boilers, but also engineering systems. In the case of this plan, all space is distributed reasonably and economically. For this reason, it is possible to avoid heating costs, since the heat emitted by pipes and boilers is quite sufficient.

Other pluses depend directly on the presence of a basement floor, and they can be listed by points:

  1. Saving space. nine0013
  2. No building load.
  3. Comfort and convenience.
  4. The ground floor is the highlight of the building.
  5. It can be arranged according to one's own desire, regardless of the style of the whole house.

Subsequently, you will not regret that you decided to build a basement, since the area of ​​​​one floor does not always allow you to place so many rooms that are actually necessary for the normal life of several people, and the construction of the second floor will cost more, than a plinth. nine0004

Remodeling of the bathroom and toilet in 2023.

2. Agreed options for remodeling the bathroom and toilet.

1. Redevelopment of the bathroom and toilet - laws and nuances. nine0042

Remodeling of the bathroom and toilet. Permission.

1.1. Enlargement of the bathroom at the expense of the room.

According to clause 7.20 of SP 54.13330.2022, such redevelopment of the bath and toilet is not allowed in apartments, in which they will be above the living room or kitchen of the neighbors below, with the exception of two-level apartments, in which the bathroom and toilet are allowed directly above the kitchen of the first level.

In other words, according to the above standards, the expansion or transfer of the bathroom at the expense of the living room or kitchen is prohibited and impossible. This also applies to the toilet, shower, restroom and so on. This rule does not apply only to the laundry room (utility room with a washing machine), since the washing machine itself is not indicated in any way on the plans of the BTI. nine0004

Therefore, from the point of view of the above, from the point of view of building codes, such works as transferring a bath to a kitchen, moving a toilet to a kitchen, installing an additional bathroom on the territory of a room or kitchen, and so on, are also prohibited and inconsistent.

Redevelopment of the bathroom and toilet with an extension to the living room is possible only if there is a non-residential premises under your apartment (in the basement or on the first floor), because then the bathroom and toilet are not above the living rooms of the neighbors below and no norms are violated. nine0004

1.2. Enlargement of the bathroom due to the corridor.

However, there are no regulations that would prohibit the transfer or extension of the bathroom and toilet to non-residential premises (corridor, pantry, built-in closet, utility room, etc. ). Therefore, it is possible to carry out and agree on such redevelopment. Also, an additional toilet or bathroom is allowed on the territory of non-residential premises.

Often, when moving or installing a bathroom, it is not possible to sewer along the walls with the desired slope, since any route taken from the sewer riser results in an intersection with the doorway. In such cases, special pumps (the most common - sololift) are installed in bathrooms and toilets, which allow you to drain sewage from almost anywhere. nine0004

Video comment:

The paragraph has changed: at the time of 2023, the approval of the expansion of the bathroom under the project is required not according to paragraph 2.2.6 of Appendix 1 to Decree of the Government of Moscow No. 508 (changing the design of floors), but according to paragraph 2.2.1 of Appendix 1 of the same decree.

From March 1, 2021, it is allowed to arrange an exit from the toilet or bathroom directly to the kitchen or room, since Decree of the Government of the Russian Federation No. 1631 canceled the SanPiN, which prohibits doing this earlier. nine0298

1.3. Waterproofing in the bathroom and toilet.

In accordance with SNiP 2.03.13-88 "Floors", bathrooms or toilets after redevelopment are required to have waterproofing in the floor structure. Thus, when enlarging a bathroom or toilet, you must dismantle the old floors in the extended area and arrange new ones with waterproofing in their place. The laying of waterproofing is documented by an act for hidden work, which is signed by a representative of architectural supervision and a builder, or a representative of the Management Company, if you are doing the repairs yourself. nine0004

At the moment there are two main types of waterproofing floors: rolled and coated. Recently, coating has become more and more widespread. The fact is that rolled waterproofing must be laid on a leveling layer of the screed. If it is laid directly on the ceiling, then under the load from the upper layers of the floor, it can break on minor protrusions of an uneven ceiling, and leaks can occur in this place during the bay. Coating waterproofing, due to its technology, does not require the installation of an additional layer of such a leveling screed. nine0004

1.4. Floor installation in the bathroom and toilet.

Permission to extend the bathroom with corridor

Repair of a bathroom with redevelopment in accordance with paragraph 4.11 "Technical requirements and rules for design, installation, acceptance, operation and repair (in development of SNiP 2.03.13-88 "Floors") until recently had to be done so that the floor level in it was made 15 - 20 mm below the level of the finished floor in adjacent rooms, or a separating threshold was installed. Now you can not fulfill this requirement if you provide floor waterproofing throughout the apartment. nine0004

Thus, it is necessary either to make the floor level in the bathrooms and toilets lower than the floor level of other rooms, or to install a threshold at the entrance to it (at least for the time the housing inspection commission arrives).

1.5. Bathroom arrangement with access to the living room or kitchen.

The redevelopment of the toilet and bathroom in the apartment used to become illegal due to clause 3.9 of SanPiN 2.1.2.2645-10 , which said , that it is forbidden to enter a room equipped with a toilet bowl from living rooms and kitchens. Now this SanPiN has been canceled, and therefore it is allowed to arrange an exit from the bathroom and toilet in any room. nine0004

1.6. Replacing a bathtub with a shower cabin - is it redevelopment or not?

Many people who contact us have a question: if we do not touch the walls of the bathroom and toilet, but only want to move plumbing fixtures within them, does this apply to redevelopment and does it require coordination? Let's try to briefly answer this question. If a portable plumbing fixture is marked on the plans of the BTI of the apartment, then changing its position entails the need to change it in these BTI plans, and this is carried out in accordance with Appendix 1 of Decree of the Moscow Government No. 508 as agreed on the basis of the sketch. The BTI plans indicate the location of the sink, shower, toilet bowl, hygienic shower and bath. Thus, work such as moving a bathroom sink, moving a bathtub in a bathroom, replacing a bathtub with a shower cabin, etc. require agreement. On the other hand, the BTI plans do not indicate a heated towel rail and a washing machine. Therefore, for example, the transfer of a heated towel rail in the bathroom does not require appropriate approval. nine0004

1.7. Remodeling of a toilet or bathroom involving shafts.

Bathrooms and toilets often have ventilation and sewer shafts with appropriate ventilation ducts and pipes. Often they have a lot of free space, which you want to add to the interior when redevelopment of the bathroom and lavatory . The laws (clause 9.5 of Appendix 1 of Decree No. 508 of the Government of Moscow) only say that it is forbidden to dismantle or reduce natural ventilation channels, but nothing is said about reducing mines without affecting the channels. However, everything is not so simple. The area of ​​these mines is not included in the area of ​​the apartment (it is not fixed in its BTI plans), which means it was not bought by the owner and does not belong to him. In practice, the coordinating authorities attribute this area to common property, referring to Article 36 of the Housing Code of the Russian Federation (although this is not clearly spelled out there), which lists the objects of an apartment building related to common property. And in order to attach common house property to an apartment (rent it or free use) in accordance with clause 2.5.1.1.1.8 of Appendix 2 of the same resolution, it is necessary to organize a meeting of the residents of the house where they will give such consent. nine0004

In other words, adding tenths of square meters from the ventilation shaft when redevelopment of a bathroom or bathroom often does not cost such high labor costs for organizing a general house meeting, and it is easier to leave the dimensions of the ventilation shaft and plumbing shaft intact in accordance with the plans of the BTI.

1.8. The installation of a toilet and a bathroom or their expansion is carried out according to the redevelopment project.

If we want to carry out the transfer, expansion or arrangement of the bathroom and toilet, then paragraph 2.2.1 of the 1st Appendix to the already mentioned Decree 508 of the Moscow Government clearly states that such work must be carried out according to the received permission for redevelopment based on the relevant a redevelopment project carried out by a design organization that has the appropriate approval from the SRO. nine0004

As you can see from the text above, renovating a bathroom with redevelopment can lead to many conflicts with the law. We hope this article will help you avoid them, but sometimes it is easier to entrust the approval of the redevelopment of a bathroom or wet rooms to professionals.
To conclude this article, we would like to give some examples of coordinated bathroom and toilet remodeling. By the way, we recommend that you read a separate article on how to coordinate the redevelopment of an apartment. nine0003

2. Agreed options for the redevelopment of the bathroom and toilet.

2.1. Redevelopment of the bathroom in the house p-44t.

Above is a typical redevelopment of a bathroom in p-44t with its integration and expansion through a corridor and a separate entrance to the kitchen through the room. In most houses, the bathroom and the toilet are made with the help of sanitary cabins of the "glass" or "cap" type. They are non-load-bearing and their dismantling is painless. The main thing, as mentioned above, is not to affect the ventilation shafts. nine0004

2.2. Alteration of the bathroom in Khrushchev.

The illustration shows a non-standard multi-room apartment for Khrushchev. A redevelopment of the Khrushchev with a small bathroom was carried out and its expansion due to the corridor.

2.3. Remodeling of a bathroom in a panel house.

after redevelopment

These illustrations show the redevelopment of a toilet with a bathtub in a panel house. In many ways, similar measures were taken here with the already considered reorganization, only this time an additional toilet was placed on the corridor area, while expanding the bathroom itself. nine0004

2.4. Redevelopment of the bathroom in Khrushchev.

But this option is already the most typical for Khrushchev and Stalinka. The corridor leading to the gasified kitchen became part of the combined and expanded bathroom, and the kitchen itself was united with the room through roller shutters.

2.5. Remodeling of the bathroom and toilet in a new building.

Small bathrooms are often remodeled not only in panel houses and brick Khrushchev houses, but also in modern new buildings. In such apartments, there are quite a lot of options for transforming bathrooms, although the most common is, as before, its expansion through a corridor.
