A wet room is a fantastic addition to any home that will give it a wow factor. It's an entirely waterproof, self-contained bathroom that typically features a sleek, modern design. As a result, it's become a trendy addition in modern homes. If you're looking to install a wet room in your home, expect to pay an average of $9,000, with a typical range between $4,000 and $15,000.

However, the final price depends heavily on how big of a space you want to convert and how complex the plumbing job will be.

How Much Does It Cost to Install a Wet Room per Square Foot?

You can expect to pay about $30 per square foot of surface area to install a wet room on average; however, it can range between $11.50 and $70 per square foot, depending on how much labor is needed and the complexity of the plumbing work. You can break down the project into the following categories.

Wet Room Project Category Price per Square Foot
Plumbing$3 – $30 per sq. ft.
Labor$3 – $20 per sq. ft.
Drywall or plasterboard$1.50 – $3.00 per sq. ft.
Bathroom tiles$3 – $15 per sq. ft.
Miscellaneous materials$1 – $2 per sq. ft.

These categories don’t include vanities, which you’ll pay for by the unit.

Installing a wet room will involve stripping down the room to the joists, plumbing the room, laying down drywall or plasterboard, waterproofing the space, laying tile, and installing vanities.

“There are many details in designing and building a wet room,” says Bob Tschudi, Expert Review Board member and Raleigh, NC-based general contractor. “Toilet paper holders need covers, floors need to be anti-slip, and there should be grab bars all around.”

Here’s how the costs break down in terms of materials and labor.

Materials

For this project, you will need the following supplies:

SuppliesCost
Waterproof adhesive$25 – $100
Plasterboard or drywall$1. 50 – $3.00 per sq. ft.
Screws $15 – $25
Fixing washers$15 – $25
Sealing tape$25 – $50
Shower drain$50 – $100
Showerhead$75 – $1,500
Bathroom tiles$3 – $15 per sq. ft.
Vanities$300 – $5,000
Mirror$40 – $300
Grab bars and handrails$100 – $500 each
Bathtub (optional)$500 – $4,000

Additionally, if you’re doing the project yourself, you will need at least the following tools:

Plumbing 

Finally, you will most likely pay between $1,000 and $10,000 to plumb the wet room. If the room is close to existing plumbing and it’s a relatively simple hookup, then costs will be on the lower end of the range. However, if it’s a complex job far away from existing plumbing, it will cost closer to the higher end. 

For example, if you install a 40-square-foot wet room—requiring about 300 square feet of tiling, including the walls—with a standard showerhead, sink, and mirror and are working with existing plumbing, you will most likely pay about $1,000. 

Labor

The cost of hiring a plumber is about $50 to $200 per hour. For a standard 40-square-foot space, it will take about 20 to 30 hours to complete the job, so you're looking at paying anywhere from $1,000 to $6,000 to get the project done in addition to the cost of materials. If you have a larger space, you will add more hours to the project; therefore, the labor cost will go up.

Cost to Install a Wet Room Yourself

If you install a wet room yourself, it’ll cost you as little as $2,000 and as much as $18,000 for a standard 40-square-foot space based on the typical price range for materials alone. The cost will be higher if the space is larger than 40 square feet. 

That means you could save $1,000 to $6,000 on labor by doing this project on your own. However, this is a difficult project that requires expertise. If you don’t do it correctly, you may have to tear out all the tiling and plumbing and do it again, which will add a huge cost to the project.

Labor is not the bulk of the cost of this project; the majority of the cost goes towards materials. So in the grand scheme of things, hiring a pro is the best way to go. Contact a bathroom remodeling near you for an estimate.

Tips to Reduce Costs While Installing a Wet Room

Fortunately, there are a lot of ways to save money on installing a wet room besides doing the work yourself.

Shrink the Space

Size is the biggest cost factor for this project, so consider trimming down on the planned size of your wet room. Reducing size by about 10 square feet will significantly affect the final price.

Shop Around for Tiles

The type of bathroom tile you choose makes a big difference in price. Ceramic and porcelain tiles have a wide range in cost based on their quality and brand. Shop around or ask your contractor to find tiles in the $3 to $5 per square foot range, rather than in the $10+ per square foot range.

Perhaps you were planning on installing a shower, bathtub, sink, and vanity in your wet room. You can potentially save thousands of dollars if you opt for a walk-in shower in place of a tub. 

Even if you want to keep all of those extras, they usually have wide price ranges. Perhaps instead of a full jacuzzi, you get a regular tub. Instead of that high-end showerhead, you can get a standard one for a fraction of the price.

Wet Room Installation Questions and Answers

What’s the difference between a wet room and a bathroom?

The difference between a wet room and a bathroom is that a wet room is entirely waterproof, even outside of the tub or shower. Wet rooms usually feature tile floors, walls, and a walk-in shower that’s level with the floor. The shower in your bathroom is basically a mini-wet-room, so think of that concept expanded to the entire room. Any water that ends up on the floor of a wet room flows into a drain in the room, which is not the case in a traditional bathroom.

“In a way, a wet room is a giant shower with a sloped floor that channels all water to a central drain,” says Tschudi. “Then it’s a matter of disguising it to make it look like a traditional bath.”

Can I turn my bathroom into a wet room?

Turning an existing bathroom into a wet room is possible, but you will likely have to tear out existing walls and tiles and install tiling up the walls and floor to waterproof the room.

Does a wet room add value?

Yes, a properly installed and waterproofed wet room will add value to your home. It's a nice modern feature that is sure to impress prospective homebuyers and can make your bathroom look bigger.

Wet room installation costs are somewhat more unknown to seasoned bathroom renovators, but this room is becoming an increasingly popular commodity in a busy family home, thanks to its practicality and durability.

Chris Scott, Joint MD, Mascot Bespoke , says: 'Wet rooms are now a staple feature of most luxury developments and refurbishments. Well-travelled clients, often time-poor, are looking to recreate that five-star luxury hotel spa experience within their own homes.'

So how much does it cost to install a wet room? As with all other bathroom ideas, installation costs for wet rooms really depend on how much reworking of pipework is needed, whether new drainage needs installing, the awkwardness of the configuration of the room, and its size, fittings and finishes. 

Chris says: 'The key to success when designing and installing a wet room is ensuring that you have the basics right. While choice of tiles, vanity units and taps may be the exciting tactile elements of the scheme you notice once the work has been done, its actually the less inspiring items that sit behind the scenes that will inform the end look and feel of the wet room. 

'For a true wet room experience, it’s preferable to avoid using a shower tray and instead tile your whole wet room, floors and walls.  Over time, grout and silicone will inevitably fail, it’s therefore key to ensure that you have the correct waterproofing system in place, which is laid on-top of the under-floor heating system and can be tiled directly onto.  

'Adding this layer does increase the cost in the short term, but pays dividends when you’re not having to pay for repairs to other rooms in the home as a result of water damage.'

We've tapped top bathroom experts to explain the costs of installing a wet room in your home below.

How much does it cost to install a wet room?

(Image credit: Future / Mark Bolton )

Nick Cryer, founder of Berkeley Place , has installed many wet rooms during renovation projects. He says: 'On average we would expect circa $11,000 (£8,000) to $18,000 (£13,000) for a medium-sized wet room, compared to say $8,000 (£6,000) to $14,000 (£10,000) for a similar traditional bathroom. 

'Overall, we would say the wet room is worth an uplift in cost. We would expect a 20% to 30% uplift for a wet room over a traditional bathroom. Most of this uplift relates to the preparation work associated with waterproofing the area. Some additional ventilation may also be required and, any radiant heating installation needs to be better planned. '

Gemma Holsgrove, associate director at interior design agency Sims Hilditch , suggests even higher. 'I would anticipate a wet room costing anything between $20,000-$40,000 (£15,000-30,000) depending on the size and level of specification.'

Average costs to install wet room components

Wet rooms can be costly. Nick Cryer says: 'Wet room installations are more specialist, more time consuming and more expensive. All the materials and kit is very readily available, however, we recommend only experts are employed to complete the installation.'

Discover how much each wet room stage might cost below. Remember that prices will vary depending on the size of the room, how complicated your wet room ideas are, and level of finishes that you choose.

Are there any hidden wet room costs to consider?

When browsing walk-in shower ideas, you may have noticed that many of the surfaces are hard – and therefore cold and unwelcoming. Therefore, you may want to add underfloor heating to your wet room for added luxury. 

Jo says: 'I believe underfloor heating is a must when fitting a wet floor tray. This can go all the way underneath the tiles in the shower so it helps to dry up water and create a much more pleasant showering area with warmth underfoot and help to combat any damp in the bathroom. '

Chris Scott, Joint MD, Mascot Bespoke , says many people are extending underfloor heating to walls, too, adding: 'Another consideration is how you will heat and vent the space. It’s no longer uncommon for clients to extend their underfloor heating systems to cover the walls of a wet room as well as the floor. This luxurious option helps keep the room at a perfect temperature but also speeds up the rate at which the tiled walls dry. Ideal for maintaining clean grout lines and a less soggy space. '

Costs for this will vary: electric underfloor heating is easy to install under tiling in an upstairs room – you can buy underfloor heating mats that are simply wired in by an electrician to your mains. If you are completing a more dramatic renovation of your entire house, and particularly on the ground floor, it is possible to have wet underfloor heating which is connected to the boiler just as radiators are.

Are wet rooms worth the added cost?

Wet rooms are worth the added costs, particularly if you are looking for small bathroom ideas for a second bathroom or en suite.  

'The finished look of a wet room is always fantastic and really finishes off a space, in particular if you have an open walk-in shower,' says Jo Sangster of Ripples. 'Of course there are alternatives on the market with many new products and tray types that can also be set flush to floor, however this will still create a divide across the bathroom and will usually make the space feel smaller.'

Transfer of the wet zone in the apartment. All norms!

Changing the area and / or moving the wet areas of bathtubs and toilets is one of the most common measures during renovation work in an apartment. Redevelopment allows you to make the apartment more comfortable and give it individual features.

Contents of the article

Wet zone in the apartment - what is it?

There is no strict definition of which places in an apartment should be classified as wet areas. According to established practice, we are talking about rooms in which, according to SNiP, there should be floor waterproofing that protects the lower floors from possible leaks.

In a residential building apartment, waterproofing is required in the bathroom, bathroom, shower room and toilet.

Wet areas often include the kitchen and laundry. These rooms are not as “wet” as a bathroom, and when laying floors in them, laying a waterproofing layer is not necessary, although it is highly recommended.

Wet point relocation

When remodeling an apartment, a combined bathroom, toilet, bath or shower is often moved to a new location or arranged in addition to existing sanitary facilities.

It is not uncommon for a wet zone to be moved when redevelopment of new buildings with free planning and in studios, where the boundaries of these premises are marked only on paper or laid out from blocks in one row.

In these cases, special attention must be paid to the laying of utilities, as there are a number of restrictions on the installation of pipelines and installation of ventilation.

The transfer of the wet zone, if there is a residential area below, can only be carried out to a non-residential area. This rule equally applies not only to the bathroom, but also to the kitchen.

Expansion of the wet zone due to the corridor

Most often, during repair work, a bathroom or bathroom is enlarged due to an adjacent non-residential (auxiliary) room - a corridor, a pantry, a dressing room or a dark room.

Expansion of the combined bathroom in the photo:

Current regulations (SP 54.13330.2016) do not allow the placement of sanitary facilities above the living rooms and kitchens of neighbors. An exception is two-level apartments, where, according to the law, it is possible to place a bathroom above your own kitchen.

It is also forbidden to enlarge the kitchen by placing it above the living rooms. And it is possible to expand the kitchen space due to the area of ​​the bathroom only on the top floor.

The exit from the bathroom should not be into the living room or kitchen. There is also an exception to this rule - it is allowed to leave the combined bathroom in the bedroom if it is not the only one in the apartment.

Waterproofing of wet areas

The current regulations provide for the mandatory presence of hydro-sound insulation of the bathroom premises, as well as the installation of an overflow dam.

To protect the apartment from the spread of water, the floor level in the bathroom is either made below the level of the corridor, or separated by a threshold more than 1.5 cm high (according to clause 4.8 of SP 29.13330.2011, updated version of SNiP 2.03.13-88)

Technical requirements for waterproofing are set out in SP 71.13330.2017 "Insulating and finishing coatings" (updated version of SNiP 3.04.01-87). Modern combined materials provide both waterproofing and soundproofing floors.

Examples of waterproofing of wet points:

Coordination of the wet zone in the apartment

Increase in the size of the bathroom, displacement and installation of additional plumbing equipment require mandatory coordination (PP-508, metro station. ZhK RF).

Coordination of repair work is carried out by supervisory authorities exercising control in the field of redevelopment, on the basis of documentation, including a project and a technical report.

An example of a redevelopment project with an increase and combination of a bathroom:

This project includes combining a bathroom (5) and a toilet (6) into a combined bathroom with its increase over the entire width of the corridor (7). The entrance to the kitchen (4) is moved.

It is possible to legalize the work performed on the basis of a technical opinion on their admissibility and safety.

In Moscow, the coordination of the planned and completed repairs with the displacement of the wet zone, as well as other redevelopment works, is carried out by the Moscow Housing Inspectorate, and in the Moscow Region by local administrative authorities.

If the whole house is one large non-residential building, and in them wet areas can be moved anywhere.

The specifics of coordinating the redevelopment of wet areas is that measures for their waterproofing and soundproofing must be formalized by an act of hidden work from a contractor with SRO approval.

Consequences of moving a wet spot in an apartment

Unauthorized enlargement or relocation of rooms belonging to the wet zones of baths and lavatories, most often does not go unnoticed by neighbors or employees of the management company. If an uncoordinated redevelopment or transfer of a wet point is found, in addition to a fine, it leads to the need to fulfill the order of the supervisory authority to restore the original state of the apartment or legalize the work performed in the prescribed manner. In case of failure to comply with the order, the law provides for legal proceedings against the owner of the apartment.

In case of preliminary approval of repair work, the stage of development of project documentation allows you to avoid activities that cannot be agreed upon later.

Waterproofing of wet areas

Waterproofing of wet areas, which include bathrooms and toilets, serves to prevent water from a sudden leak from penetrating to the lower floors within a specified time.

For example, when expanding these premises, the floors on the attached area do not protect against water in any way. Another option is the dismantling of bathrooms or partitions between the bathroom and the toilet: water seeps into poorly sealed grooves in place of the former partitions.

That is, if an unauthorized redevelopment of a bathroom or toilet was carried out in your apartment, then with a high probability it can be said that the installation of waterproofing of wet areas in the bathrooms was carried out incorrectly, or even completely absent.

Suppose you have combined a bathroom and a bathroom, and in addition you want to attach a part of the corridor to it and move the plumbing. According to all the rules, the first thing you had to do was prepare the relevant documents, order a redevelopment project from a specialized organization, and only then proceed with waterproofing wet rooms. But this is not always the case. And if you decide to do the work at your own peril and risk, inviting a team to redevelop the bathroom according to an ad in the newspaper, then the consequences of such work can be the most unpleasant for both you and your neighbors.

When redevelopment is legally agreed upon, laying waterproofing of floors in bathrooms refers to the so-called hidden works, and the correctness of its implementation is controlled by drawing up a certificate of examination of hidden works and field supervision. To be more precise, paragraph 4 of Appendix 7 of PPM 508 refers to works requiring activation, waterproofing of toilets, bathrooms, balconies and showers.

Checking the waterproofing of wet areas and its quality is carried out as follows: a layer of water about 5 cm thick is poured into the bathroom and left for 2 hours. If during this time no leaks were found on the floor below, then the waterproofing of the bathroom was done correctly.

However, in self-planned renovations, hired builders usually don't bother laying, much less checking waterproofing layers. And, as a rule, they do not have the right to draw up acts (for this you need to have an SRO permit). Therefore, even with a small accident, the water does not remain in your bathroom on the floor, but immediately “leaves” to the neighbors on the lower floor. For those who are planning to carry out redevelopment on their own, it will be useful to know that in most cases it is the occurrence of an emergency that causes the housing inspectorate to find out about your redevelopment.

Subsequently, you will not only pay a fine, but you will also have to repair the consequences of leaks in your neighbors' apartment. And, of course, if the work was carried out in violation of building codes, then there can be no question of coordinating redevelopment "backdating", and all expensive repairs will have to be redone.

Therefore, in order to avoid possible troubles, especially if the work is related to the laying of waterproofing of wet areas, it is best to take care of obtaining permits in advance and coordinate the redevelopment in advance with the Housing Inspectorate.

Relocation of the wet zone in the apartment. All features in 2022.

Relocation of wet areas, as well as other types of repair work on the redevelopment and / or reorganization of the apartment, must comply with the current building and sanitary standards for multi-apartment buildings, providing comfortable living conditions and safe living for all residents of the house.

Therefore, the first thing to do at the stage of redevelopment planning is to find out how, according to the current legislation, it is possible and how not to carry out the transfer of a wet spot in an apartment building. And the second - how and where to issue permits for the legal implementation of such redevelopment.

You can find answers to all these questions in our article.

Premises with wet processes

However, before moving on to the essence of the issue under consideration, let's define which rooms in the apartment belong to wet zones.

Real estate wet spot: what is it?

A wet zone or a wet point is a room with high humidity (because there is a source of water), in which floor waterproofing is mandatory. These include: bathrooms, latrines, toilets, showers and shared bathrooms.

Is the kitchen a wet area or not?

FAQ: Is the kitchen a wet area? No, the kitchen area is not considered a wet spot. If you need detailed information on how to legally carry out a kitchen relocation in an apartment, go here.

Redevelopment with the transfer of wet spots

Before the owner, who has set himself such a task, there will be two sides of the issue: technical and legal. We'll take it apart from both sides. And let's start with a review of the technical nuances of this procedure.

Is it possible to move the wet area in the apartment?

From a technical point of view, it is not so difficult to carry out such a redevelopment. First of all, when transferring a bathroom, it is necessary to bring under the place of the future restroom communication, in simple words - a drain riser and cold water for draining. A drain riser with a diameter of 100 mm is allowed under a slope of 2 mm, and with a diameter of 50 mm - under a slope of 3 mm. Cold water can be supplied using any available materials, be it metal, polypropylene or metal-plastic.

Of course, no one wants to enjoy the sight of open pipes in their apartment, and therefore the desire to somehow hide them in the wall is understandable. In this case, you can arrange a plumbing box, but a mandatory item in this case will be the installation of an inspection hatch on it, with the help of which access to those pipes will be provided.

This scheme works only if the bathroom is planned to move at a distance of no more than 5 meters. Otherwise, it would not make sense to implement such a project due to the fact that the natural slope of the drain pipe will raise the toilet bowl to a height unacceptable by the layout of an average apartment, and a half-meter podium will turn your toilet into a throne room.

But even in this situation there is a solution: a forced sewage system. If you do not go into the nuances, then it is a pump with a grinder.

The forced sewerage system has two significant advantages: the discharge takes place through pipes of smaller diameter (20 and 32 mm) and can be carried out not only horizontally, but also vertically up to seven meters high. Currently, there are many models of forced sewage systems with different designs and from different manufacturers.

However, the technical side is not the only thing that should worry you. In addition, there are a number of sanitary and construction rules that must be followed when moving a wet zone to the territory of a former kitchen or a corridor in an apartment.

Wet areas in the room and kitchen

According to SP 54.13330.2016, it is strictly forbidden to place wet areas above living rooms and kitchens (including kitchen-dining rooms and kitchen niches).

Basically, apartment buildings are built in such a way that one riser on all floors of the apartment has the same layout. That is, toilets are above toilets, bathrooms are above bathrooms, kitchens are above kitchens, rooms are above rooms.

During the redevelopment, the location of the premises in the apartment where renovation work is being carried out relative to other apartments will be changed. It is not prohibited by law to change the planning solution of an apartment, but at the same time it is impossible to worsen the living conditions of neighbors.

If, for example, a toilet is moved to a part of the area of ​​the living room of your apartment, then it will be above the living room of the apartment located on the floor below. And clause 9.22 of SP 54.13330.2016 prohibits doing this, so this option for redevelopment of the apartment cannot be agreed upon.

The same applies to moving the toilet to a part of the kitchen area. The existing rules do not allow the location of wet spots directly above the kitchens.

Therefore, in most apartments it is impossible to coordinate the redevelopment with the transfer of wet areas to the territory of the room or kitchen. However, there are several exceptions that allow this event to be carried out without violating the above-mentioned norms:

Let's briefly comment on the listed exceptions, in which the wet spots in the apartment can be moved/expanded to the area of ​​the kitchen or living room.

The owner's apartment is located on the first floor of a residential building. In this case, there are no obstacles in coordinating the redevelopment project, since there can be no residential premises below. And even if there is a basement under this apartment, this will not affect the approval process in any way.

The floor below is completely occupied by non-residential premises. As a rule, this applies to apartments on the second floor. Or when the first floor was originally non-residential. Or when the ground floor apartment was transferred to a non-residential fund to be converted into a shop, boutique, service center, etc.

In this case, it will be necessary to additionally attach to the set of documents submitted for consideration any document proving that a non-residential premises is located below. There is no clear regulation on the form. This can be like a certificate from the management company that there is a non-residential premises under your apartment on the ground floor, a BTI certificate, photographs of the facade with a clear link between your apartment and the premises on the lower floor, etc.

Under the area of ​​expansion / transfer of a bathroom or a bathroom to a kitchen or a room, there is a non-residential premises of apartment , for example, a dressing room, pantry or hallway. This option is possible if the owner of the apartment below has completed and officially agreed on the redevelopment of the transfer or increase in the area of ​​the above premises at the expense of the kitchen / room.

That is, in this case, we are not located above the area of ​​the kitchen / room, but above the area of ​​​​another room, which, before the redevelopment was agreed, belonged to the kitchen / room of the neighbors below.

Second floor of a duplex apartment. In practice, such a case is extremely rare. However, it is also an exception in which the owner has the right to place his wet area above his own kitchen.

If the bathroom (toilet) in the apartment on the floor below is already enlarged by part of the kitchen (room) area. In practice, we have not seen such a case, but theoretically it is possible. Here, again, there must be non-residential premises under your neighbor’s apartment below, otherwise he would not be able to agree on this redevelopment. And then, within the same boundaries as that of a neighbor, you can transfer or enlarge the bathroom at the expense of the kitchen (living room).

This option looks something like this.

Suppose there is an apartment on the ground floor. The owner can safely enlarge the bathroom at the expense of the kitchen. He did and agreed. Further, the owner on the second floor can make exactly the same extension, and so on. We also note that if any of the owners, for example, on the fourth floor does not want to do such a redevelopment, then on the fifth floor the homeowner will no longer be able to agree on this, despite the fact that on the first, second and third it is already agreed.

Redevelopment project with the transfer of the wet area to the kitchen.

Comments on the approved redevelopment project. The apartment is located on the second floor. During the redevelopment, the kitchen (4) was moved to room (3). This became possible because the neighbors downstairs also have a kitchen in this place. And a bathroom (6) with a toilet (5) in the form of a combined bathroom (4) was transferred to the former kitchen. Such redevelopment became possible because below, under the new bathroom, there is not an apartment, but a landing.

Transfer of the wet spot to the corridor

If there are serious restrictions when moving the premises of the wet zones to the living room and kitchen, which have already been mentioned, then the transfer of the wet zone to the corridor or storage room / built-in wardrobe / dressing room is almost always possible to agree, although carrying out such redevelopment also has some nuances.

As already mentioned, SP 54.13330.2016 prohibits the location of bathrooms and toilets above living rooms and kitchens.

Therefore, if a neighbor living in the apartment below officially made a redevelopment with the extension of the room (kitchen) to the corridor, then this fact will make it impossible to agree on the transfer of the toilet or bathroom to the corridor in your apartment, since your toilet / bathroom in this case will be above the extended part of the neighbor's room (kitchen), which would be a violation of current regulations.

If the downstairs neighbor did not make redevelopment with the addition of the corridor or part of its area to the kitchen or living quarters, then you can agree on expanding the wet zone through the corridor or arranging the wet zone in the corridor by moving it in your apartment.

Redevelopment project with the transfer of the wet spot (toilet) to the corridor.

Comments on the redevelopment. In this case, the toilet (6) was moved to the corridor (8). As a result, the passage to the kitchen (5) was blocked. To create a new entrance in the load-bearing wall between the kitchen and the room (4), a doorway was cut out and reinforced with metal structures. The former toilet room was combined with an adjacent bathroom (7) and thus arranged a combined bathroom (7).

Relocation of the wet area to a closet with access from a hallway, hallway or hallway is a permitted renovation measure. But if the entrance to the pantry leads from the kitchen or room, then the transfer of the toilet or bathroom to the pantry is carried out according to the same rules as the transfer of a wet point to the room or kitchen.

An example of moving a toilet to a storage area.

Comments on redevelopment. The toilet (2) in the apartment was moved to the closet (7), the entrance to which was originally arranged from the corridor (6). As a result, a combined bathroom (7) with an entrance from the bedroom (5) was arranged on the site of the pantry and part of the corridor area. It turned out to be possible to arrange an entrance to the bathroom from the living room, because the apartment has one more combined bathroom (8) with an entrance from the corridor (10).

In general, the transfer or increase of the wet area due to the corridor, pantry or built-in wardrobe does not cause problems in coordination. To agree on this redevelopment, design documentation is required as part of the redevelopment project and a technical report. In general, such work can be coordinated both by the owner independently and with the help of an organization that specializes in redevelopment design.

Can the wet zone be reduced?

Since usually in residential buildings wet spots are rooms that have a small area, the goals of redevelopment, as a rule, are:

But in rare cases, the owners ask if it is possible to reduce the wet zone in the apartment?

Redevelopment of the wet zone in the apartment, when it is required to reduce its area, is allowed, but only the norms mentioned above must be observed. That is, it is of fundamental importance how the area freed from the bathroom or bathroom will be used in the future.

An increase due to the wet zone of the corridor, pantry or utility rooms is quite feasible. But using a wet point to expand a room or kitchen is allowed only on the top floor, because in other cases the kitchen / room will be under the wet zone of the neighbors from above, which will not be agreed upon.

What must not be done when moving wet areas?

Speaking about prohibitions when moving a toilet, it is worth noting that when carrying out this type of redevelopment, it is prohibited:

  1. Use a balcony or loggia to accommodate a room equipped with a toilet. It is forbidden to transfer a bathroom, as well as a bathroom, to a balcony (loggia), regardless of which building and on which floor the re-planned apartment is located.
  2. Arrange the floor in the toilet / bathroom without waterproofing, drawing up acts for hidden work. That is, floors in wet rooms must be lined with waterproofing material .
  3. Attach plumbing and plumbing fixtures to walls and partitions that separate the toilet from living rooms.
  4. Violate the requirements of the Code of Rules "Floors" (SP 29.13330.2011), according to which the floor in the toilet and bathroom must be 15-20 mm lower than in the adjacent corridor, or separated by a threshold also 15-20 mm high.
