Doors for the bathroom and toilet - Beautiful options for the best design (90 photos). Secrets of a successful purchase: choosing doors for the bathroom and toilet Which door is better to install in the bathroom

Doors for the bathroom and toilet are different from those that are installed for other rooms. They should be practical, and at the same time fit into the whole house. Before buying doors, read the tips on how to choose the right one.

Criteria for choosing a bathroom and toilet door

Regardless of whether or separate, you need to carefully consider the issue of buying doors for the bathroom and toilet. How to choose so that you do not have to change after a few years? To begin with, you should take into account the specifics of the rooms. Doors for them must be resistant to moisture, dampness and steam. Because of this feature, the fittings (hinges, handles, latches) must be more durable than in other interior structures.

Doors for the bathroom are more difficult to choose than for other rooms. After all, such doors must be durable, soundproof and resistant to moisture.

If there is an extractor hood in the room, and it works properly, there should be no problems with humidity. However, take into account how often and how long you plan to use the bathroom. It largely depends on the number of family members. Also, when choosing a door structure, consider the size of the rooms and how the plumbing is located in them. It is important that the doors are well insulated from sounds and retain heat.

What material to prefer

Most manufacturers of interior doors use:

wood (including MDF, chipboard and veneer);
glass;
plastic.

Sliding doors from natural wood

Wood

The peculiarity of wood doors is that they can “breathe”: absorb and release moisture. In the bathroom, this process can be especially noticeable - the doors swell. To prevent this from happening, you need to regularly paint them or open them with varnish. Antiseptic treatment will not be superfluous. Wood breaks down when splashed with water. Therefore, such doors are not suitable for small rooms.

Advice. So that the door frame does not squint over time, it should initially be securely fixed. Use anchor bolts for this and mounting foam.

The advantages of wood doors include:

look noble and create comfort in the apartment;
made of high quality material (usually oak or beech);
with proper care, using an antiseptic and varnish, they can serve for a long time.

Doors made of natural wood, although expensive, are very beautiful and durable.

Cons of wood products:

are very expensive;
due to high humidity often covered with cracks, which forces the owners to periodically restore them;
caring for them is very expensive.

Chipboard, MDF, veneer and laminate.

The first two materials are pressed wood boards, and veneer is a thin sheet of wood cut in a special way. They are very common in the production of doors. But nevertheless, experts warn of the fragility of such structures, if we are talking about installing them in a toilet or bathroom. According to the reviews of the owners, doors made of these materials swell quite quickly and stop closing normally, in addition, they are unstable to strong impacts.

Laminated doors

The advantages of wood-based panels include their low cost. They fit well into the interior of the entire room. However, instability to high humidity is the main disadvantage of installing in a bathroom. The same applies to natural veneer doors. They look like real wood, but they serve much less.

TO budget options“under the tree” also includes laminated doors. These are the same MDF structures, but covered with a laminate - a special film. It protects the door from moisture, is easy to clean, inexpensive, has a wide variety of patterns.

Laminated doors fail quite quickly

However, there are many disadvantages of such a door:

low level of sound insulation;
the impossibility of restoration (in case of serious damage, it will need to be replaced);
external unpresentability (look very simple).

Attention! Doors made of MDF, chipboard and veneer contain formaldehyde, which can cause individual allergic reactions.

Glass

For doors to the bathroom and toilet, manufacturers use a particularly durable material that is difficult to break.

Glass doors, despite the external fragility, are quite durable.

Other advantages of these structures are:

resistance to moisture;
good sound insulation;
environmental friendliness;
ability to keep warm;
variety of models;
external attractiveness;
Thanks to the glass, the room visually enlarges.

Glass doors are very beautiful, but require careful maintenance.

Flaws glass doors for the bathroom:

settling of condensate, which leaves streaks on the glass;
frequent care (it is necessary to wipe the glass regularly to give it a neat appearance);
high price.

Advice. Despite the strength of bathroom glass, in a house with small children it is better to additionally cover it with an impact-resistant film.

Various types of plastic

This material is well suited for wet areas. A plastic door is cheaper than a glass one, but it also has many advantages:

not afraid of exposure to water and steam;
lasts long enough;
retains heat well and isolates noise;
has many finishes;
is hygienic;
easy to care for.

Plastic doors

The disadvantages include the rapid deformation of such doors in the event of a large load on them. With this in mind, manufacturers produce more durable designs. They are equipped with special tabs that reinforce the product (increase strength), or are made on an aluminum base. There are such metal-plastic doors more expensive than usual.

The main types of door designs

Door design for toilet and bathroom

Choosing door structure for a bathroom, you need to pay attention to how harmoniously it will fit into the interior. For example, laminate doors are almost identical in pattern. This can be handy if you plan to put them in all rooms. Often manufacturers decorate such structures under stone or wood.

Plastic products are distinguished by a wide variety of palettes. This allows you to choose desired color doors, combining it with other elements of the apartment or house. However, perhaps most of all designers pay attention to glass. Doors from it are made opaque, decorating them:

Diverse door design for bathroom and toilet

stained glass paints or multi-colored glass;
gold and silver paints, creating a coating;
sandblasting materials, etc.

Besides, glass doors happen opaque, mirror, relief. Often they are complemented by inserts made of wood, metal or plastic.

Often, toilet and bathroom doors are smaller than other designs. This is due to the fact that a low threshold is usually placed at the entrance to the bathroom. It is useful to take careful measurements before buying.
A ventilation grill can be mounted in a wooden or plastic door for a bathroom. This solution is suitable for rooms that do not have natural ventilation.
When installing sliding doors, additionally use insulating gaskets.

What door to put in the bathroom so that it does not deteriorate from high humidity, is durable, reliable and beautiful? Not every material will be able to withstand the specific conditions of service without consequences, so it would be impractical to choose a door, guided only by its compliance with the interior. Let's figure out which doors are better to put in the bathroom according to the type of construction, material and external design.

Wood MDF Plastic
Glass Mirror Stained Glass

To withstand the operating conditions in the bathroom, the door to the bathroom must be resistant to high temperature and humidity, provide good air exchange and sound insulation, and have antiseptic properties. What materials will meet these high requirements?

natural wood

Solid wood bathroom door - good choice if it meets the following requirements:

has an external water-repellent coating of paint or varnish;
treated with antiseptics;
made of hardwoods that absorb moisture poorly (beech, oak, mahogany).

It is important to properly install the door unit. So that the box does not bend over time from constant exposure to hot steam and water, it is fixed using anchors and mounting foam. If these conditions were met during selection and installation, in the future its durability will depend on proper care. Against constant humidity and evaporation external protective covering loses its properties, and it must be updated from time to time, otherwise cracks may appear on the canvas.

Covering from MDF or fiberboard

Manufacturers of doors made of MDF and chipboard assure that the products are absolutely not afraid of moisture. In fact, the construction consists of a frame made of pine, which is characterized by high hygroscopicity. The design has water-repellent properties due to the outer finish of the canvas: the laminated coating is resistant to moisture, but until chips and scratches appear on the surface. There are other vulnerabilities: backside box for which water-repellent protection is not provided. In just a few days of operation, the wood can swell, and the door will no longer close completely.

Products made of MDF and chipboard have an affordable cost, a wide the lineup and a wide range of colors are their main advantages. To ensure their long service life, it is necessary to process all open areas boxes protective composition, make sure that the edge of the leaf is glued with high quality and has no gaps, protect the surface of the door from damage.

metal-plastic

If you are going to purchase doors to the bathroom and toilet, and doubt which ones will last better and longer, take a closer look at metal-plastic structures. Aluminum and plastic, the main components of these doors, have a lot of advantages:

resistance to moisture, temperature changes and cleaning agents;
strength and durability;
resistance to deformation;
simple hygiene care;
lack of a nutrient medium for putrefactive bacteria and fungi;
low cost.

Choosing a door to the bathroom with a design similar to other designs installed in the apartment will also not be difficult: the exterior decor of metal-plastic PVC film allows you to get any color and texture.

Glass

Glass door - very good an option for the bathroom, given the resistance of this material to moisture. There will be many disadvantages of such a design:

When turned on hot water the glass surface is constantly covered with condensation. Moisture flows down the smooth panel, accumulates in puddles on the floor and leaves stains.
Water stains, splash drops, fingerprints are very clearly visible on the glass surface, therefore, such doors need constant hygienic care.
Glass is a fragile material, and if it is broken, it is also dangerous. So that in case of damage to the glass door it does not crumble into small fragments, the surface is protected with a special film, and this affects the increased cost of products.
The low level of sound absorption is another drawback.

The design of glass doors is very diverse. It is customary to install deaf structures in the bathroom, so designers solve the issue of glass transparency in various ways: they create stained glass drawings, spray paint, paste over with a film or matte.

Types of doors by opening method

Swing Sliding Folding

What is the best door to put in the bathroom according to the method of opening? Manufacturers provide several designs to choose from.

The swing door is the usual standard option, quite convenient, if only they allow square meters. The design consists of a box and a sash attached to it with hinges. Provided that the bathroom is usually modest in size, the door leaf opens outward. This saves space in the bathroom. It is necessary to install such a door taking into account that it does not block free access to other rooms in the open state.
A sliding door does not require additional space in the room, but for it it is necessary to leave a free part of the wall where the sash will move. There is another option: equip a groove inside the wall where the sash will go when opened. In this case, the door will not interfere with the use of free space.
The folding design "book" or "accordion" has the only drawback - poor sound insulation. This design is compact, open form occupies a minimum of space.

Color selection

What color to choose doors for the bathroom and toilet? The entrance to the bathroom, kitchen and rooms is usually located in the hallway. To avoid color dissonance, most rational solution- choose the same shade for all designs. If the door block delivered to the bathroom is made of a different material, care must be taken in advance so that the decor of the doors is in harmony with the interior in color. It can be a colored textured PVC film, a similar pattern on glass and similar fittings.

Hardware features

Choosing the door to the bathroom, you need to take care of suitable fittings. These are hinges and a latch handle. It is desirable that the design of the chosen option matches the fittings installed on other doors of the apartment. To check the quality of products, you should pay attention to the following points:

Door hinges should not creak. High-quality fittings open smoothly, but with little effort.
A lock with a magnetic latch has a shorter service life compared to a mechanical one. Pay attention to the tongue of the lock. A plastic tongue creates less noise when closing than a metal one.
You can determine the quality of a door handle by its weight. The iron core, which is characterized by a long service life, is much heavier than the unreliable silumin - the material for cheap Chinese products. The handle spring must be elastic.
In order for the door to be locked from the inside, the handle must have a locking device. More reliable in operation is the option when the latch is included in the handle kit, but is located separately during installation.

All door hardware should be covered by a warranty. If the store refuses to issue a warranty card, it is better to refrain from buying.

Rating of manufacturers

Before choosing the doors to the bathroom and toilet, we suggest that you familiarize yourself with the rating of manufacturers.

"Alexandria Doors"- Ulyanovsk factory. Modern equipment from Germany and Italy allows us to produce products of European quality.
"Volkhovets". The doors of this brand are produced in Veliky Novgorod. Buyers are provided with a very wide range of products in a variety of styles.
"Dera". For more than twenty years, the Penza company has been producing its products. The manufacturer offers a unique design, high quality and affordable prices.
"Stendor"- practical, elegant, durable doors from St. Petersburg. The factory is equipped with imported equipment.
"Sophia". The Tver factory recently upgraded its equipment. Products are made in accordance with international standards.

World famous foreign brands:

Tre Piu is an Italian company. It offers non-trivial models with finishing elements made of aluminum, impact-resistant glass, veneer, precious woods.
Garofoli- a huge range of models from the Italian manufacturer.
Dana is an Austrian company. It has been supplying its products to the world market for over 40 years.

Products well-known manufacturers characterized by decent quality. The durability of the product depends not only on how to choose a door, from what material, and from which manufacturer, but also on correct execution installation work, timely hygienic care and careful handling.

Replacing the doors in the house is a serious undertaking that requires a balanced approach. Special attention should be given to wet areas. Not all materials can be used there. Choosing doors for the bathroom and toilet is far from easy, as many nuances must be taken into account.

Requirements

Doors to the bathroom and toilet are chosen not only in appearance. Their properties must also be taken into account. In bathrooms, high humidity is not uncommon, so moisture resistance is an important characteristic. Equally important is the good tolerance of wet cleaning. This is another selection criterion. Durability and reliability are also important. Also important are properties such as sound insulation and low thermal conductivity. In the bathroom, we feel comfortable with more high temperature, and it is easier to create it with a door that has good thermal insulation ability.

There are also technical nuances. According to building standards doors to the bathroom and toilet can be made narrower than to living quarters. It is this situation in apartment buildings. In private houses and cottages, this rule is rarely followed, and even during repairs, or often, doorways of ordinary sizes are also made.

There is another nuance. For quick removal moist air requires well-functioning ventilation. It can be natural or forced (with a fan), but for it to work well, there must be an influx of fresh air into the bathroom. To open up the air door leaf make 1.5-2 cm shorter, leaving a gap in the floor area. It just sounds scary, but in practice this gap is almost invisible. The second way to ensure the flow of air - special ventilation grates that are embedded in the door leaf. And the third is the supply holes in the wall. Of all the options, it is the idea with a gap near the floor that is the least striking. It is also the easiest to implement.

What are the doors for the bathroom and toilet

In the bathroom and toilet they put even the most ordinary doors- wooden or paneled (wood frame with plywood inserts), painted with paint. With well-functioning ventilation, they serve well, only few people like them. Therefore, they prefer to replace them with new, more modern ones.

Wooden and veneered

Solid wood doors are undoubtedly beautiful, but also expensive. They are placed in a damp room if they are covered with a layer of varnish. In this case, manufacturers in the description usually indicate that they are "waterproof". Provided that a good varnish is used and it is correctly applied, the coating protects against moisture and washes well. If necessary, the varnish layer can be updated, although this operation will not be required soon.

Veneered doors are made from inexpensive low-grade wood, and then pasted over with expensive veneer. A veneer is a thin saw cut of a tree - a few millimeters thick. The presence of glue makes veneered doors not quite "natural", but at the same time protects the wood from swelling. However, veneered bathroom and toilet doors are not the most the best choice, because the veneer is not hermetic, moisture penetrates into the smallest cracks, due to which the surface warps and the veneer begins to peel off.

Wooden doors - expensive and beautiful

Not so long ago, doors finished with euro veneer appeared. This is a new material consisting of wood and a binder. Colored wood fibers are mixed with a synthetic binder. This mixture is forced through a powerful press and comes out in the form of a ribbon. In appearance, the resulting material is practically indistinguishable from natural veneer, and surpasses it in performance properties. Doors finished with euroveneer are not afraid of high humidity, the coating has a high mechanical strength and will not fade in the sun. You can distinguish them by touch - too smooth coating.

If we talk about other characteristics, it can be noted that wooden and veneered doors for the bathroom and toilet have low thermal conductivity and protect well from noise. Wet cleaning they endure, but soft cloth and without aggressive detergents.

Plastic and metal-plastic

Plastic doors to the bathroom - an economy option. They are inexpensive, they are not at all afraid of water in any of its conditions, they are not deformed by high humidity. Their disadvantages are that they are made from unnatural raw materials, inexpensive models have low mechanical strength. It is also worth remembering that they cannot, like wood or veneer doors, be “fitted” to the desired size.

Plastic - good material for wet rooms

Metal-plastic doors in the apartment bathroom are rarely installed. But not because they don't fit. Rather, they are not used for aesthetic reasons - their appearance is very different. If doors made of other materials are installed in other rooms, it is very difficult to choose a more or less suitable color. Another deterrent is the high price. And the features are better than you can imagine.

glass

Glass - not very popular as doors, but has good characteristics. It does not react to water and high humidity, it does not rot and you can wash it as much as you like. They have one drawback - fragility, but modern technologies overcome it - the glass is made tempered, which gives it increased strength. There is also laminated glass (duplex and triplex). This is when sheets of glass are glued with a reinforcing film.

It is possible to break a glass door leaf, but it is difficult to do it, and if it does, the glass breaks into many small fragments with smooth, not sharp edges. In the case of laminated glass, the fragments hang on the film, and the tempered glass simply breaks into small fragments, but you have to try hard to get hurt by such fragments. The only trouble from such an event is the need to buy a new door.

Glass door leaf can be colored

Glass doors for the bathroom and toilet are made opaque. They are tinted, can be mirror coated or stained glass painting. All that is visible through such doors is a blurry silhouette and no specifics. In general, a good option if the family does not have small children.

Laminated and PVC

Another inexpensive option bathroom doors - laminated with foil. The door leaf itself is made according to frame technology. The frame is made of pine timber, the gaps are filled with soundproofing material (the cheapest ones are corrugated cardboard, more expensive - polyurethane foam), after - sheathed with laminated fiberboard or MDF. The surface of the door can be decorated to look like wood, it can be smooth (much less common).

The door leaf is light, but it does not tolerate shock loads very well. At good quality lamination, such a door to the bathroom and toilet is not afraid of moisture, and it is washed well (with a damp soft cloth with liquid non-aggressive detergents). As long as the lamination remains intact, it looks quite decent. With intensive use, the film is erased and appearance noticeably worsens.

PVC bathroom doors are made using the same technology. The only difference is that the frame is sheathed with extruded PVC. The density and strength of PVC are many times higher, so the durability is also higher. Performance is also better: vinyl is not afraid of water in any form, so for the bathroom and toilet it is a great option.

Combined

When they say combined doors, they most often mean that they have inserts of a different material. And most often it is glass inserts. Glass sizes can vary greatly. This may be a narrow strip along one of the edges or big piece half the door. Glass is also used opaque, tempered or laminated. If the glass in the model you like is too transparent, you can stick a self-adhesive stained glass or translucent film on it.

Combined options - the most interesting in terms of design

Glass inserts are made in wooden, metal-plastic and veneered doors. Less often - in MDF and almost never - in plastic. But the most interesting design models are found in this category - more room for imagination.

Opening systems

Besides different materials bathroom and toilet doors can have different types opening. The usual option for us - swing doors. They are good for everyone, except that in the open state they cover a solid gap of space.

becoming more and more popular in Lately. This is when a bar is attached to the top of the door, rollers are attached to the door leaf, the doors roll along this bar. According to the method of mounting the guide, sliding doors are open and secret. Open - when the bar is attached to the wall on one side, and the canvas rides along the wall. With a hidden system, a niche is made in the wall into which the door leaf drives in.

The second option in the open form takes up almost no space, but during installation it requires serious intervention in the wall structure, which is far from always possible. It is unlikely that it will be possible to hollow out a niche in a concrete or even brick partition right size. Then, in order to hide the canvas, they build a false wall of drywall.

The disadvantage of sliding doors is more complex installation, and at open systems — low degree soundproofing (the canvas simply hangs along the doorway, solid gaps remain). In secret systems, everything is better in this regard - there are door frame, with a groove into which the door leaf enters and a seal in this groove. Such systems have good sound insulation, but are expensive.

Folding - accordion (right) and book (left)

Another view. There are two types - "book" and "accordion". Doors-book have a door leaf, consisting of several parts. These parts are movably connected; when opened, they fold, resembling a book. Accordion doors have a similar structure, but fold differently: relative to an axis passing through the center. Book doors are often made of glass, they can also be made of MDF or plastic, in accordion doors they are often made of plastic and they cost a little.

High humidity and temperature, splashes of water and soap suds - not only the floor and walls in the bathroom are exposed to all these aggressive influences. The bathroom door is also under threat - meanwhile, special models are rarely found in manufacturers' catalogs with photos. In such cases, it remains to buy ordinary serial products - this will also help to create. Indeed, according to modern design canons, doors should be the same or designed in the same style.

Which door is best for the bathroom

When developing technology, most manufacturers take into account that their products will be used, including in wet rooms. However, this does not mean that any of the models on the market is suitable for a wet area. We tell you what to look for when choosing.

Which material is best for bathroom and toilet door

First, consider what materials are generally used.

Lamination

It is produced as a base and a layer of paper glued to it - this is called the lamination process. But they are not glued to ordinary glue, but with the help of special resins. But still there are gaps into which moisture can penetrate. Perhaps one of the few options devoid of this drawback is laminatin. It is thicker and varnished on top for better protection. Fabrics treated in this way can withstand humidity up to 60%.

PVC coating

Such models have an MDF base, and a PVC coating on top. It is water repellent and can even be washed. The advantages include a wide variety of colors and textures of these interior doors - it will be easy to choose the one you like for the bathroom and toilet. But there are also disadvantages - the canvas can exfoliate from too high humidity. And when the temperature rises in the paving, PVC can release chloride - for those who strive for it, it is better to abandon this type.

Ecoveneer

modern material, which is produced from woodworking waste and polymer plasticizer. Despite the complicated name of the latter, it is environmentally friendly. Eco-veneer is difficult to distinguish from natural material externally, but it even surpasses real veneer in quality. Among the advantages are resistance to moisture, aesthetics and environmental friendliness. But it can become an argument not in his favor.

Wood (veneer)

Too capricious, and is unlikely to show itself well in the bathroom. But if you choose a product coated with high-quality varnish, it is quite possible to install it. The frame of veneer products is made of softwood or chipboard, but outer side already covered with natural wood.

Plastic

Perhaps, if you are looking for an answer to the question of which door to put in the bathroom and save the budget, this is exactly your option. Raw materials are inexpensive, so ready product available. Plastic is not afraid of temperature changes or moisture, as well. And the sound insulation of such models, as a rule, is on top.

But do not rush to draw an unambiguous conclusion - especially if aesthetics are important to you. Plastic products are rarely beautiful, and they are also made standard form, and any deviations are not possible. Also, it is not eco-friendly.

Glass

Glass structures absolutely waterproof, but the thickness of the canvas must be at least 8 mm, otherwise it will not be possible to provide sound insulation. In addition, it must be taken into account that products decorated with sandblasting (matte and with a matte pattern) become transparent when moistened, and any relief pattern ( laser engraving, fusing) will greatly complicate the care of the surface.

It is better to give preference to hardened structures with colored ceramic coating or triplex - plain color, with a pattern or photo printing. Glass products will last longer in the bathroom than any other, while it is easy to choose the option that matches the style of the apartment.

So which material is the best? Pay attention to alternatives to wood: eco-veneer, plastic and glass. And only if the room is spacious enough and well ventilated, you can think about laminated, natural wood (veneer) and PVC-coated. When choosing the latter, the type of coating on the web and edge is of great importance. If the joints are not tight, moisture will penetrate in this place and the product will deteriorate.

Which door to choose in the bathroom by design

There is traditional options- swing and other designs. Let's consider each.

swing

A classic that is used in all rooms. It has a standard frame: a box, platbands are placed. You can also put thresholds, and this improves sound insulation. The standard swing type opens inward or outward, and there must be room for this. If inside - there may be problems with this.

sliding

The design of the coupe is very space-saving, which again is useful in small spaces. But during installation, a gap remains between the floor and the canvas, which means that heat and sound insulation will be reduced.

You can compromise and install a model that slides into the wall - this is only possible before starting capital works, since you need to ditch the wall. With such sliding options, the disadvantages are minimized.

folding

Structurally divided into a book and an accordion. In the first case, the canvas is divided into two parts, and in the second - into three or more. When folded, they take up space in the opening, so the space savings are essentially negligible.

6 things to consider before buying

1. The presence of decor

Paneled structures are made from solid wood, according to the generally accepted opinion, they are unsuitable for a bathroom. However, this is not always true. If the frame of the structure is made of glued beams, and the panels are made of high-density fibreboard (HDF), and at the same time the canvas has a multi-layer coating (high-quality polymer enamel or varnish), then it does not care about water. The likelihood of warping and cracking is minimal, and the finish will withstand both high humidity and frequent washing.

And shield (smooth) canvases, as practice shows, are quite capable of withstanding the conditions of the “home tropics”. Such models are distinguished by stable geometry, because their frame (usually made of ordinary coniferous bars) is protected from moisture by sheathing. But the service life of the latter depends on the type of decorative coating.

2. Transparency

The presence of frosted or tinted glass often raises questions. From an aesthetic point of view, it looks nice and good, but how practical and is it suitable for a bathroom? The fact is that sound insulation is good only if the glass is dense, from several layers.

3. Size selection

Usually the bathroom and toilet should be about 194-196 cm in height and 60 cm in width. Meanwhile, the minimum height standard door block for many companies it is 204 cm. The design of the required dimensions can be made to order (it will cost 10–20% more, and it will hardly be delivered earlier than in 2 weeks). Another option is to file the canvas, after checking with the manufacturer how to do it correctly. Usually, 100 mm can be cut off from panel sheets both from below and from above, but then a strapping bar should be glued in place.

There is always an extractor fan in the bathroom. Moreover, in many apartments it is designed to serve adjacent premises. And it will function normally only if a gap of at least 8 mm is left between the floor and the canvas. But such a gap will adversely affect sound insulation, so it is better to build it into the door ventilation valve with silencer ( approximate price- from 1,200 rubles).
