A modern kitchen requires not only functionality, but also aesthetic completeness, where every element of the interior is in its place. Building in a refrigerator a niche made of plasterboard is a popular solution that allows you to hide large appliances and harmoniously fit them into the overall design of the room. This design visually expands the space and makes the interior more formal and tidy, hiding unnecessary details.
However, before taking up the tool, you must clearly understand that a refrigerator is not just a cabinet, but a complex technical device that requires a special approach to installation. Drywall is an excellent material for creating box, but it does not tolerate moisture and requires proper preparation of the base. Errors at the design stage can lead to overheating of the compressor or deformation of the structure.
In this article we will analyze in detail the entire process: from calculating dimensions and choosing materials to finishing and organizing ventilation. You will learn which profile is best to use, how to correctly calculate the indentations for air circulation and what nuances should be taken into account when working with moisture-resistant plasterboard. By following the instructions, you can create a reliable and beautiful niche that will last for many years.
Design and calculation of niche dimensions
The first and most important stage is the accurate calculation of the dimensions of the future structure. You cannot simply measure the refrigerator and make a box according to these dimensions, since the equipment needs space for normal operation. Heat transfer is a key process that must not be disturbed, so gaps must be provided on all sides, especially at the back and top.
First, decide on the installation location and take accurate measurements of the refrigerator itself unit. Please note that modern models often require air supply from the front (through the plinth) or from the rear, depending on the system No Frost or static cooling. If you plan to integrate equipment into a finished set, make sure that the depth of the niche will allow the doors to open unhindered.
When calculating the width of the niche, add at least 5-10 cm to the width of the refrigerator on each side to lay communications and provide an air cushion. The height of the structure must be such that the top gap is at least 10-15 cm for hot air to escape. The minimum distance from the back wall of the refrigerator to the wall or drywall should be 7-10 cmotherwise the motor will wear out.
Don't forget to provide space for sockets It should not be located directly behind the refrigerator, as this will increase the depth of the niche and may lead to heating of the wire. It is best to place electric point on the side or on top in order to have access to it at any time without moving the equipment.
⚠️ Attention: Never design a niche without taking into account the direction of opening the doors. If the model does not support reversing the hinges, make sure that there is sufficient space on the desired side to fully open the door by 90 degrees or more.
Necessary tools and materials
The quality of the final design directly depends on the materials chosen. For a kitchen where high humidity and temperature changes are possible, ordinary drywall will not work. You will need moisture-resistant plasterboard (GKLV), which is usually green in color and contains special additives that prevent the development of mold and deformation of the sheet.
The niche frame is assembled from a metal profile. The optimal choice would be a brand profile CW and UW (or their analogues PS and PN) with a metal thickness of at least 0.5-0.6 mm. A thin profile can “lead” under the weight of the structure or under an accidental mechanical impact, which will lead to cracks in the finishing coating.
To attach the profile to the walls and floor, you will need dowel nails, and to connect the frame elements to each other, you will need metal screws (the so-called “bugs” or “seeds”). Also stock up on reinforcing tape (sickle tape) for seams, putty for drywall and deep penetration primer.
- 🛠️ Cutting tools: metal scissors for profiles, a construction knife with spare blades for drywall.
- 📏 Measuring tool: tape measure, laser or bubble level, plumb bob, square.
- 🔌 Power tools: hammer or impact drill, screwdriver with magnetic attachment.
- 🧱 Consumables: screws 3.5x25 mm (for gypsum boards), dowel-nails 6x40 mm, sealing tape.
When purchasing materials, always take them with a reserve of about 10-15%. This applies to both plasterboard sheets and the profile, since during the cutting process, trimmings are inevitable that cannot be used in other places in the structure.
Marking and assembling a metal frame
Assembling the frame begins with marking the floor and ceiling. Using a laser level, project lines where the vertical posts will be located. It is important to maintain a strictly vertical position, since any distortion at this stage will lead to difficulties when installing sheets plasterboard and the appearance of cracks in the corners.
Fix the guide profiles (PN) along the perimeter of the future niche: on the floor, ceiling and adjacent walls. Be sure to lay damper tapebetween the metal and the surface, which will improve sound insulation and compensate for thermal expansion of the structure. The spacing of the dowels should be no more than 50 cm.
After installing the guides, install vertical racks (PS) in increments of 40 or 60 cm. If you plan to hang shelves or heavy decorative elements on the niche wall, the rack spacing should be reduced to 40 cm or double reinforcement should be made in load areas. The racks are attached to the guides with metal screws.
☑️ Checking the frame before covering
To give the structure rigidity and the ability to attach sockets or shelves, horizontal jumpers are mounted between the vertical posts. They are made from the same profile by cutting the sides and bending them. Pay special attention to the upper perimeter, where the niche ceiling will be formed niche ceiling.
Installation of drywall and creation of ventilation holes
Sheathing the frame begins with cutting sheets according to previously taken dimensions. It is convenient to cut drywall with a construction knife: make a deep cut along the ruler on the front side, then break the sheet and cut through the cardboard on the back side. It is advisable to process the edges of the cut with a gypsum board plane in order to remove the chamfer for subsequent putty.
Attach the sheets to the profile with self-tapping screws in increments of 15-20 cm. The screw caps should be slightly recessed into the material, but do not break through the cardboard, otherwise gypsum over time it will begin to crumble. Start covering from the corners, moving towards the center to ensure symmetry of the structure.
A critically important point is the organization of ventilation. In the lower part of the niche (in the basement area) and in the upper part (under the “ceiling” of the niche), it is necessary to cut holes and install ventilation grilles. The open cross-sectional area of the grilles must be sufficient for the free passage of air, otherwise the refrigerator will overheat.
If the refrigerator requires air intake from the rear, holes can also be provided in the rear wall of the niche (if it is not a load-bearing wall of the house), covered with a decorative mesh. In some cases, the back wall of the niche is not sewn up at all, leaving access to communications and the wall of the building.
⚠️ Attention: Do not cover the ventilation openings with dense materials or decor without installing grilles. Impaired air circulation will lead to an increase in electricity consumption and a reduction in the service life of the compressor.
Is it necessary to insulate the niche?
Insulation of a niche from the inside is required only in one case: if the wall to which the refrigerator is adjacent is external and freezes heavily. In other cases, additional insulation is not necessary and even harmful, since it reduces the useful volume and can create a “thermos” around the operating unit.
Putty joints and finishing
After installing the sheets, it is necessary to prepare the surface for painting or wallpapering. The first step is priming the entire surface, which will reduce the absorbency of the material and improve the adhesion of the putty. Pay special attention to the seams and places where screws are screwed in.
The joints between the sheets are glued with reinforcing sickle tape and puttied with a special compound for seams. After the first layer has dried, a second, thinner layer is applied to level the surface. The places of the screw heads are also carefully puttied so that they do not show rust through the finishing coating.
Acrylic paint, which is resistant to washing and wet cleaning, is ideal for the kitchen. Before painting, the entire putty surface must be sanded with fine-grained sandpaper and primed again. This will ensure an even color without stains. latex or acrylic paint, which is resistant to washing and wet cleaning. Before painting, the entire putty surface must be sanded with fine-grained sandpaper and primed again. This will ensure an even color without blemishes.
If you plan to glue wallpaper, choose washable options with high density. In places where the niche is adjacent to the floor, it is recommended to install a plinth, and along the upper perimeter - a decorative molding or corner, which will hide possible uneven joints.
| Parameter | Recommended value | Note |
|---|---|---|
| Gap at the back | 70-100 mm | For free air circulation |
| Gap at the top | 100-150 mm | For warm outlet air |
| Pitch of profile posts | 400-600 mm | Depends on the load on the walls |
| Indoor humidity | up to 70% | Requires the use of GKLV |
| Operating temperature | +5...+30 °C | Optimal mode for equipment |
Installing the refrigerator and checking the operation
After the finishing coating has completely dried, you can begin installing the equipment. Before sliding the refrigerator into the niche, make sure that all internal surfaces are dry and clean. Check whether protruding parts of the profile or unevenness of the putty do not interfere with the free movement of the unit.
Carefully place the refrigerator in place, being careful not to damage the walls of the niche. Connect the equipment to the power supply using a pre-prepared outlet. Turn on the refrigerator and let it run idle for several hours to make sure the temperature is stable.
Pay attention to the noise level. A drywall niche can act as a resonator, increasing the hum of the compressor. If you notice an increase in sound, check to see if the vibrating parts of the refrigerator are touching the walls of the box. If necessary, you can glue the inner walls vibration-isolating material or penofol.
Regularly check the temperature inside the niche in the first days of operation. If the walls of the box or the air around the refrigerator become noticeably hot, this is a signal of insufficient ventilation. In this case, it may be necessary to increase the area of the ventilation holes or install an additional exhaust grille.
⚠️ Attention: Do not install the refrigerator close to the walls of the niche “back to back”. Even the slightest distortion of the floor when extending can lead to scratches on the drywall and damage to the body of the equipment.
Frequently asked questions (FAQ)
Can I use regular drywall instead of moisture-resistant one?
Using regular plasterboard in the kitchen is highly not recommended. Even if there is no visual moisture, the air humidity increases during cooking and washing dishes. Ordinary plaster will quickly absorb moisture, swell and become moldy. Moisture-resistant drywall (GKLV) contains additives that protect against dampness, which is critical for the long service life of the structure.
Do I need to make a door for a niche or should the refrigerator be open?
It depends on the design of the kitchen. If the refrigerator is freestanding, it is usually left open, with a niche framing the sides and top. If you want to completely hide the equipment, you can hang furniture facades on the frame, but this will require a complex system of guides and taking into account the weight of the doors when calculating the frame.
What if the floor in the kitchen is uneven?
If there is a significant difference in floor heights, before assembling the frame, it is necessary to level the base or use adjustable supports for the profile. Ignoring this step will cause the vertical studs to “lead” and the drywall sheets may crack. This will also make it difficult to install the refrigerator itself.
What is the minimum thickness of drywall?
For vertical structures, such as a niche, the optimal sheet thickness is 12.5 mm. Sheets with a thickness of 9.5 mm are too thin and will not provide the necessary rigidity and strength, especially if you plan to attach shelves or accidentally rest on the walls.
