How to plan the interior of the bathroom, combined with the toilet?
Bathroom planning involves taking into account a number of requirements. First of all, it must be functional. However, when the bathroom is combined with a toilet, the list of underlying factors increases. In order for the room to meet all the stated requirements, it is necessary to properly plan its interior, taking into account the peculiarities of combining, repairing, finishing and decorating, as well as the arrangement of furniture.
Special features
A bathroom combined with a toilet is a combination of two separate rooms according to their functionality. Previously, it was one of the problems of small-sized city apartments. Due to the lack of usable space, the place was barely enough to accommodate a bath and a toilet.She didn’t even have to think about the washing machine: she often had a place in the pantry or hallway.
The problem of such rooms exists today. It is aggravated by an insufficient ceiling height, a broken prospect, the presence of obscure protrusions that do not carry any functional load. Often the place under the bath and the toilet is selected extremely inconvenient. Moving inside such a bathroom is difficult. The narrow doorway, the side of opening the door and the inconvenience of approaching it complete the list of inconveniences.
However, the prospect is not the main factor. What matters is the supply of communications, as well as the degree of humidity of two rooms. The bathroom is a room with a high level of moisture. There is often condensation, the load on all components of the interior is increased significantly. Ventilation must be carefully designed.
Due to the connection of two rooms of different functionalities, a kind of separation of zones that are dangerous by moisture level occurs. For the toilet area it is fraught with the fact that the toilet can be wet. His tank will almost always be wet outside. The abundance of condensate will cause water to drain to the floor, which over time can damage the structure of the flooring.For this reason, for cladding surfaces will have to buy materials with maximum resistance to moisture.
Combined bathroom determines the set and size of furniture, type of finish for walls, ceiling, floor. The location of storage systems and accessories depends on the location of the bath, wash basin and toilet. One of the positive aspects is the saving of space, which is especially important for apartments with a lack of usable space. Due to this, you can give the situation ergonomics, practicality and a certain comfort.
The absence of a wall reduces the cost of repairs and surface finish. There will be no second door. Savings will affect including cleaning products, as well as time for cleaning. However, the most positive nuance is the possibility of masking communication systems. It is often difficult to implement in the conditions of the toilet due to the reduction of usable area.
From an aesthetic point of view, a combined bathroom has more opportunities for interior design. Today, there has been a tendency to give the bathroom the appearance of living space under a certain style that expresses the inner world of the owners of the house.Modern units are more like rooms adapted to the bathroom and toilet. The position of exceptional functionality without an aesthetic component is outdated.
In such rooms furniture is installed for storing hygienic and other accessories, dressing tables, benches, chairs, dressers with mirrors, cabinets. For the convenience of all members of the family wash equipped with two sinks, add a bidet. Custom solutions are distinguished by the presence of household appliances. Usually it is built into niches, which will be used depending on the layout, including under the hidden location of washing and drying machines, as well as baskets for dirty laundry.
The combination of two rooms makes room for accessories. Today it is customary to decorate bathrooms with fresh flowers in vases, setting them on dressing tables or niche shelves. An unusual reception is the decoration of the wall for hours or panels. A look at the arrangement of the bathroom sticks to the importance of the aesthetic component. Comfort is transmitted through the texture of all elements, including finishing materials, their color, effect, and compliance with the conceived idea of stylistics.
An interesting solution to masking bearing elements is to use columns as supports. The space is freed, while the columns support the design of the ceiling and allow the use of frame design systems. Demolition of the wall allows the bathroom to be as functional as possible when free centimeters are enough to install a cheap cabin.
Separately or jointly - what's best?
The planning of a bathroom and toilet separately is often not subject to the general concept. It does not oblige to select the same type and color of finish for wall, floor and ceiling ceilings. There may be various plumbing accessories (fixtures, valves). However, when two rooms are connected into one, the situation changes. We have to combine the toilet, sink, shower and bath in a single style. This is a mandatory match of texture and form.
For a toilet, combining with a bathroom is not the best solution. We will have to abandon some types of material that can be used for separate rooms. For example, it is undesirable to use paint, even if the manufacturer claims its durability and impeccability.In conditions of constant exposure to moisture, it quickly moves away from the surface. Some analogues are completely erased during cleaning, which raises the question of their relevance.
For the bathroom, the neighborhood with the toilet is the opposite. Often this is due to the wiring of pipes. When the riser in two rooms alone, it is convenient. No need to hold the pipe for a few meters, you can get rid of many connections and unnecessary bends. However, this is the case when the bath and the toilet are located near the riser.
Combining the bathroom and toilet is sometimes a necessary measure in the construction of buildings. For example, if there is little space left for construction, it has to be left for other needs. This is especially true if the house is being built for a family. In this case, you have to think through the degree of convenience at the design stage of rooms.
However, not everyone likes the combination. Often this is due to unpleasant odors, the simultaneous use of the room by two family members. In addition, the wall-divider can be bearing. An independent connection is accompanied by a pile of necessary documents and coordination with the requirements of the regulations.
The combination of bathroom and toilet allows you to set the standard furniture in the room. Often, a joint bathroom allows you to efficiently use the space. The meters, which are disposed under the toilet (the distance to the wall ceilings), can be used to install the shelves, shelves, cabinets or washing machines. In each case, the choice of subject matter is individual. In general, the combination can be called the best use of the dwelling space.
Combination options
The fundamental factors of each combination are 3 zones: washing, bathing (shower) and toilet. Important wiring diagrams of engineering communications. Everything else is auxiliary moments of arrangement, whether it be a joint bath with a toilet in a panel house or a private building. This is necessary when three or more people live in the apartment. The layout can be different (with a shower, without it, only the cabin). The correct option is the one that meets the regulations and user convenience.
For example, you can install a bath to the wall opposite the entrance, on the one hand to fix hanging furniture with a sink.Near the bath you can mount a flush toilet.
If the bathroom is not provided, the shower area can take its place. The arrangement of the furniture may be linear. One wall is left almost empty (except for the heated towel rail). On the opposite side set the table with a sink and a mirror.
Bath can be located along the wall at the entrance. Then the toilet can be issued opposite the door. The washing machine should be installed on the wall opposite to the bathroom.
If there are very few centimeters of space, you can get by using an angular shower instead of a bath. The toilet is better to fix nearby. For washing you should choose an elongated shape.
If there is a niche in the room, you should use it for the installation of a washing machine and hanging drawers. Then the toilet can be put in the corner, and the bath of a compact size can be placed next to it.
If the room is spacious, you can use the reception partitions. For example, the separation of the shower and the wash zone will be successful. The toilet can be isolated by setting it away.
When you want to install both a bath and a shower, you should use the corner options.One corner of the bathroom is closed, the second - a cabin, toilet and sink are located on both sides of the bath and shower.
In a confined space, you can install a sink and a bath in one wall, fixing the toilet on the side of the adjacent wall in relation to the sink.
Dependence on the area
It is no secret that it is the square that sometimes puts a rigid framework for the placement of plumbing and furniture. When the footage is limited, the comfort of the interior is questioned. The difference between the dimensions of a very small space, say, in 2 - 4 square meters. m and a room in 5 - 6 square meters. m is obvious. It does not put a closet or even a small cabinet for the necessary supplies.
In small apartments the comfort of residents is not thought out. A bathroom may not be sufficient for an overweight person. Sometimes the width of the doorway to the joint bathroom is 60, at best 70 cm. The size of the bathroom in a small apartment is difficult to find, because you have to think about the location of the toilet so that it does not interfere. Option two: demolish the wall or change the bath in the shower. The design with a shower will free valuable centimeters.
In a confined space, one has to get along with a heated towel rail, which is mounted mainly to the wall in a free space. This is not very convenient, but functional.On the crossbar you can always hang a bath towel, bathrobe, linen. In tiny bathrooms such devices are attached to the door.
In a large joint room, in addition to the functional, comfort is felt. Starting from 6 m2, it is already possible to arrange a free wall with a cabinet with drawers or a stand with legs. If there is a sink with a sink, you can make a screen, buy furniture with a stone worktop, hang a mirror in the frame from above. It is even better when there are small niches on this wall. They can be used for the storage of hygiene products or towels.
Design
Drafting a combined bathroom complies with a number of requirements. If it is carried out at the time of construction of the house, try to choose the best way to construct the bearing walls. Design will allow a more rational approach to the issue of communication. Due to it, it is possible to organize the supply of water and electricity as conveniently as possible without disturbing the aesthetic side of the issue.
Make up a design project. It indicates the exact dimensions of the combined room, plotted the location of each object, including shelves in niches and accessories.This will allow a better view of the future interior, assess the degree of convenience of the location of furniture and plumbing. For a more visual method using special computer programs. Due to the introduction of the required meter designers allow you to make several types of design at the discretion of the customer.
Design allows you to evaluate the ergonomics and convenience of the interior composition, choose the best option, taking into account the freedom of movement. It also clearly shows the location of the lamps, their distance from the dangerous zones (60 cm or more to the side of the bath, the height of about 2.3 m from the floor). At this stage, the total power is calculated so that the lighting of the combined bathroom is sufficient.
Convenience of work of designers is the accounting of a different form of the room. In the program you can see how best to create the interior of a rectangular, square, sloping space perspective. Particularly relevant planning narrow bathroom, combined with a toilet. Usually in such cases it is linear. For example, a toilet with a bathroom is placed right next to one wall.
Much worse, when the layout was originally combined not in the best way.Sometimes at the entrance to such a bathroom, the average person can see a corner bath, which hardly fits into the length of the wall. Often there is no room for washing. A toilet zone is set aside, creating discomfort when moving. Designing such an option involves adjusting the premises with the best placement of the necessary plumbing elements.
Repairs
Repair of the bathroom, implying its transformation into a cozy space for hygienic and natural procedures, involves the calculation of the amount of finishing materials, its proper purchase and use. It is important not only to buy a quality veneer suitable for decorating the bathroom. Matters its relevance from an aesthetic point of view. For example, the abundance of one finish will make the bathroom interior boring.
Expressive texture gets only when comparing. Therefore, the walls, the ceiling, as well as the floor try to trim the different in color and pattern of raw materials. It matters the location of the finish. The best approach, in the opinion of stylists, is the allocation of functional areas to the finishing material.
The more creative the material, the more moderate its use.For example, when allocating a wall with an invoice for a brick, one has to abandon the mass of accessories. Usually such a design implies a minimal version of the bathroom decoration. Other walls will have to be smoothed, for example, with plain coatings without any pattern at all.
Finish
The range of finishing materials for registration of the combined bathroom is various. In priority, certain types of raw materials, subject to the list of developed requirements related to the conditions of bathrooms.
Particularly relevant is a few.
- Resistance to moisture. The material should not pass it through the structure to the enclosing structures.
- Environmental friendliness. In priority - facing without harmful components that can cause damage to the health of the household.
- Antistatic. The best choice is the finish, resistant to the formation of the environment for the emergence and reproduction of mold fungi.
- Strength. The selected type of cladding raw materials should not suffer from random mechanical effects.
- Compatible with any type of lighting devices. The material should not melt with a long-running lighting device.
- Fire resistanceSurfaces of walls, ceilings or floors must not sustain combustion in the event of a short circuit.
- Optimum weight. Facing products with a large weight creates an additional load on the carriers. In some cases, this causes the deformation of the overlap.
- Durability. Repair in the bathroom with a toilet do not make often. Coatings must be held firmly on the base of the ceiling, floor and walls.
- Resistance to fading. In priority, the finish with a protective layer that does not allow the tone to become faded.
- Ease of care. The coating should be cleaned with clean water and a rag (sponge).
- Resistance to abrasion and chemical reagents. The best finish is the one whose surface remains unchanged with frequent cleanings, including using household chemicals.
- Aesthetics. In priority finish with a pleasant external performance.
- Availability. The best material is the one that an ordinary buyer can afford.
Types of finishing materials
More often, wood, plastic, reinforced glass, tile, mosaic, moisture resistant gypsum board and stretch film are used in the arrangement of combined sanitary facilities.Each type is characterized by its features and durability. The wood is treated with water-repellent impregnation. This avoids stratifying the structure.
Drywall
Plasterboard sheets are used mainly in spacious bathrooms, combined with a toilet. GCR is characterized by compliance form. Due to this, it is possible to create any shapes from it, besides the traditional box. Apply it to the arrangement of the ceiling, the construction of partitions, remote from the dangerous (wet) areas. Thickness is enough to hold decorative elements and even thin tiles.
This material is quite fragile. It is necessary to work with it extremely carefully to avoid dents during installation.
It is a good basis for various finishing materials. Compatible with any type of lighting fixtures from pendant lights and near-surface to point and fiber optic.
Stretch film
The best option based on PVC for decorating the ceiling space. The film perfectly keeps water in case of leakage from the apartment from above, is easy to clean, has a matte and glossy type of texture. It is not subject to decomposition from condensate,supports embedding of lamps of any kind, including optical fiber and tape. Due to the special technology can be on the surface of the figure.
This allows you to convey the right atmosphere and hint at belonging to a particular style of interior. Photo prints are made to order by an individual picture processed in a graphic editor. Finishing is durable, does not lose saturation and purity of shades, it is eco-friendly. The disadvantage is the need to warm it up and place it before the tension to 60 degrees. This can be done through a heat gun, which usually does not have an ordinary head of the family.
Tile
Universal material for decorating surfaces of walls, floor and ceiling. It differs in thickness, size, shape. It is sold mainly in the form of geometric shapes. With regards to the ceiling variety may have a wavy edge, the appearance of an octagon. Gluing such material implies a seamless fixation technology.
Options for the walls are able to reproduce an unusual texture. Due to the unusual shape and thickness heterogeneity in different parts of the element, cladding with imitation of facade materials is possible.Floor materials are distinguished by greater thickness and resistance to weight and mechanical loads, as well as vibration of the washing and drying machines. Perfectly combined with mosaics and inserts of self-leveling three-dimensional epoxy resin-based floor.
Mosaic
Reduced interpretation of tiles. It can be ceramic, rubber, glass, stone, differs in a variety of texture. Sometimes glossy, matte, mirror, transparent, imitates gravel, cork, stone. On sale is presented in two categories: traditional and netting. In the first case, it is laid in a modular way, part by part.
The second version is nothing more than a mosaic glued to the grid. It is easier to glue, there is no need to align the seams between the elements. This saves time for surface finishing. The disadvantage is moderation. When there is a lot of mosaics in the bathroom interior, it creates emotional tension and becomes tiresome for the eyes.
Panels
There are wall and ceiling. Depending on this, they are made of plastic, metal, glass, wood. For the ceiling, wood and plastic derivatives are used.If cassettes are used for the frame, they can be made of thin metal sheets with mirror inserts.
Foam for ceiling decoration is not suitable. Its structure permits moisture, which is associated with glue deacidification. Wall types can be represented by siding for interior decoration and wall panels of different widths. Connection provides locking technology.
Reiki
The material is plastic. Reiki differ in different widths and wide imitation possibilities. Perfectly combined with drywall, can be a decoration of the surfaces of walls and ceilings. Depending on the flatness of the walls and ceilings, they may have glue or frame mounting technology.
The adhesive method is used when the space of the combined bathroom is limited to a minimum. The frame system reduces the distance from the wall to the location of the slats by 10 cm on average. The technology can be suture and seamless. Externally, both have joints, only differ in width (the seamless gaps are smaller).
Glass
This raw material is not basic, but it is often used as shower curtains, shelves and furniture fronts.Differs enhanced view, may have a traditional transparent, mirror or painted type of decoration. It is used to decorate the ceiling with original tiles-cassettes with locking connection technology. It looks stylish, expensive, has the ability to make any interior light. The disadvantage is the visualization of calcareous stains left on the surface from moisture.
The color and nuances of the combination
The choice of shade for the design of a combined bathroom depends on the taste preferences of the customer, the room footage, its degree of illumination, and the effect of color on perception. Modern professional interior designers are able to reveal the beauty of each tone of the color palette. A creative look allows you to combine bold contrasts, related colors, making the interior of the bathroom multi-faceted. The inept combination often looks rustic, so the choice of tone should be solid.
Conventionally, the collection of paints can be divided into 4 lines:
- neutral;
- natural;
- pastel;
- saturated.
All directions are clean tones, their softness and a kind of muffled.Neutral design is popular, but mostly in a spacious room. When space is not enough, it will be to the limitations, some hopelessness. Of course, you can try to change the atmosphere of hygienic accessories color palette. By itself, this design is devoid of emotional coloring. The way out of the situation is the addition of wood tones, as well as the color of juicy greens and olive.
Natural gamma today in the spotlight. It is traced in every branch of interior design. It is used in the decoration of the walls, the tone of the bath screen, its design, the lid or the decoration of the toilet bowl, the facing of the shower cabin. The traditional method of infusion of wood shades is floor cladding. Less commonly, it can be seen in accented places zoning the combined bathroom (niches, ledges, mirror zone, the color of artificial stone tops). The most popular tones are dark and bleached wenge and shade of Sonoma. Popular mixes of light gray with beige, as well as a combination of black and brown colors.
Pastel gamma is one of the usual solutions. Along with the traditional marine colors (blue, turquoise, blue-green) mint, peach, bleached coral and terracotta shades are added to the palette.Look good in the interior of the combined bathroom olive, dairy, cream and beige tones. When adding gold or bronze color, they look elegant. Ivory shade is also in demand, as well as pearl tone with light mother-of-pearl.
With regards to the rich colors of the palette, the combination is special. Today it is customary to combine them softer. To do this, use a bonding color. For example, combining black and terracotta tones will help light gray color. Wine (orange) with white looks harsh, but when you add a creamy golden perception soften. Gold can dilute the mix of woody and black. Silver will make a more pleasant contrast of purple and black.
Particular attention is paid to the natural tones. When choosing a particular texture, it is especially important that the shade looks natural. It should reproduce the imitation of marble, stone, brick, concrete, lime, malachite. There should be no acid and crying in tones. This trend is outdated, in the center of attention the nobility of any color or the right combination. You can use up to three different textures in one design.In this case, the main color can be related, and the degree of saturation varies.
Lighting
Depending on the room footage, ceiling height, the presence of projections, partitions and niches choose lighting. Often the central luminaire in the combined space is not ideally located in the center of the room. It is necessary to compensate for this disadvantage by means of composite lighting. This is a combination of the ceiling center and auxiliary lighting. Combined lighting can be placed on the ceiling and walls.
Since the requirements for light sources for the bathroom are high, they use LEDs more often. They are harmless, do not flicker at power surges, are designed for a long service life. Unlike analogs, the diodes do not heat up; they convert into light practically all the power consumed. With a minimum of energy shine brightly, but directionally.
The restriction of the direction of the light flux is associated with the formation of dark spots. It turns out that only the area under the lamp is illuminated. In order to illuminate the entire area of the combined bathroom, it is necessary to additionally use an auxiliary light,often positioning it with equal spacing between spotlights.
Some luminaires have an angle adjustment system. This is especially useful when you need to highlight a mirror or dressing table. Sometimes, to solve this problem, mirrored canvas with built-in lighting around the perimeter is bought. In another case, fix the lights above and below the mirror for uniform illumination. If this option is not possible, buy two identical wall sconces and attach on both sides of the mirror at the middle of the side faces.
The main rules of purchase are closed type of lampshades, durable materials, safe light sources. The presence of fences that prevent the breaking of the lamp is welcomed. A good option are LED panels, spots, lamps with reflectors and flexible LED strip. The number of LEDs per square. m should provide a soft but sufficient level of luminous flux.
Decor
Decorating the bathroom, combined with a toilet, carried out in several ways:
- through compositional backlighting;
- due to the same finish plumbing;
- taking panels and emphasizing individual functional areas;
- through the texture of the selected material;
- at the expense of accessories;
- method of indicating the belonging to a particular style of interior.
With proper and deliberate approach to interior design, you can use several methods of decoration. For example, plumbing in any case should create the illusion of an ensemble. This should be reflected in the same round shape, color and dullness (gloss). You can add plumbing silver, chrome valves tank button, spout and shower.
Background wall decoration should not blend in color with plumbing, otherwise everything will merge into a single color spot. The material for the separation of the bath, the sink and the toilet should have as little relief as possible. This will simplify the care of coatings. Checkout thresholds better contrasting color. Their emphasis will eliminate stumbling at the entrance to the combined bathroom.
Tiles are selected based on the size of the room. If it is small, the plates should be smaller. In this case, the grout is better to choose light, so as not to visually split up the room into many parts.Do not need extra variegation: monochromatic coverage will be enough. Dark colors will not work here: they will visually make the interior heavy, uncomfortable.
For the floor pick porcelain or ceramics muted color. A successful decision would be to buy marbled tiles, planks, parquet. If you want new solutions, you can design in the form of a carpet. This will allow to beat the most passable zone. For example, you can lay out a picture near the bathtub, frame its edges with a border, and make the rest of the area in one-colored material.
Design ideas are different. It is possible to combine floor tiles with epoxy floors. An accent with a photo print framed by a perimeter tile will look unusual in such a room. You need to have such an accent in an open place, where there will be no furniture or sanitary ware.
It is better to pick up furniture after finishing works. The interior can be made stylish, based on fashion trends. However, if the furnishing details are already there, the decor is adjusted to them.
For example, a stylish solution is the simulated texture of wood cladding, painted board, stone, brick, and even concrete.
Smooth tiles better decorate the shower area. For the floor it is preferable to purchase a material with anti-slip and a matte texture. Ceiling material is usually an abundance of tile or siding. Its decoration will be the backlight, including the class RGB. The ability to change color will allow users to immerse themselves in any atmosphere at will.
Furniture
Furniture for the bathroom is selected from materials that are resistant to moisture. Usually install products from certain varieties of the array, as well as plastic and metal. Not suitable for arranging a bathroom combined with a toilet, products from MDF and fiberboard. Under the influence of steam, their structure is destroyed, which reduces the service life. Wood is treated with special antiseptic and water-repellent impregnations.
Most often, such products are installed as far as possible from the bath, shower and sink zone. In the shower, they think over the ventilation system, additionally separate the space with glass curtains. This protects the furniture to some extent from destruction. Sometimes the set is mounted in a niche that makes room for movement around the room and saves from accidental bruises.
Usually in the design of the bathroom try to use the cabinet, dresser with mirror,closet or shelving If the place is very small, costing shelves. Ideally, these are shelves of glass, mounted in niches. The stand with legs is convenient because you can remove a lot of items, including detergents. This helps to get rid of the visual sensation of disorder, hiding inside the mass of small parts.
When there is enough space, a dressing table is installed in the room. It can be an independent product or part of a furniture ensemble, custom-made for the bathroom. Usually the addition of such a wall are chairs. Sometimes the arrangement includes benches for rest with comfortable backs, and sometimes armrests. They allow you to relax after a bath.
One of the unusual elements of furniture is a stand for the bathroom. It helps elderly households to climb into the bath, because often in this age movement is limited. The product can be made in the form of a ladder. Rarely a washing machine is installed in modular furniture. Modules themselves are convenient, allow the purchase of only those parts that are suitable in a particular case. However, they are not suitable in every case due to non-standard planning of the combined bathroom.
Ready projects for inspiration
You can evaluate the possibilities of a professional designer’s view of a combined bathroom by referring to examples of photo galleries.
The combination of gray, brown and bronze color with a contrasting wine insert of one of the zones. Finishing plumbing sustained in a single design. Dark tone softens the white ceiling and furniture.
Creative approach to the separation of functional areas. The combination of white and brown, using a single chrome finish. Separate backlighting accentuates each functional area.
Scandinavian style with its inherent ease. The combination of white with dark and light wood contrasts. Stylish bathroom design with a small window.
The use of one side under the shower and a place for the toilet. The use of different textures to highlight each functional area. Identical metal fittings plumbing and accessories.

Prima mixing matte and glossy textures. Rational approach to the arrangement in a limited space. The use of separate lighting for the washing area.
In drawing up the interior for a particular room, it is difficult to completely copy the finished project. This is not necessary, because the inner perception of each is different. Attempting to reproduce someone else's example does not always allow for comfort. In addition, the stores are unlikely to be identical facing and furniture, and the budget often does not coincide with the desired.
You can take as a basis for placing the principles of the layout of the toilet, washing and bath. It will be useful to build on the methods of choosing the color, taking into account the footage, peering into the beautiful pictures. These are the basics with the help of which it is easier to understand and choose the best design option for your own premises. Sometimes examples avoid the demolition of a wall between two rooms.Not in every case it is permissible: sometimes the removal of the carrier causes the wall to sink.
