A refrigerator is an indispensable assistant in the kitchen, but over time, even the most spacious models begin to run out of space. The problem is especially acute when standard shelves do not fit in size or configuration. Instead of buying a new unit or overpaying for branded accessories, you can make a refrigerator shelf with your own hands - it's cheaper, faster and allows you to adapt the design to your needs.
In this article you will find 5 proven ways making shelves from different materials: from durable glass to food grade plastic and stainless steel. We will analyze in detail what tools you will need, how to take measurements correctly, avoid mistakes when cutting and fastening, and also give advice on caring for homemade shelves. We will pay special attention safety —after all, the shelf must withstand the weight of cans, bottles and other heavy products without the risk of collapse.
Regardless of whether you want to replace a broken shelf, add an additional tier or optimize the space under non-standard products (for example, tall bottles or large baking sheets), our instructions will help you cope with the task without special skills. All methods have been tested in practice and are suitable for refrigerators Atlant, Samsung, Indesit, LG and other popular brands.
1. Choice of material: what is best for a homemade shelf?
Not only the appearance of the shelf, but also its strength, durability and safety for products depends on the material. Let's consider the pros and cons of each option:
- 🔹 Tempered glass - aesthetically pleasing, easy to clean, can withstand high loads (up to 20 kg per shelf). Suitable for modern refrigerators with transparent elements. Disadvantage: requires care when cutting (it is better to order a cut in a workshop).
- 🔹 Food-grade plastic (PET, polypropylene) - lightweight, does not rust, does not react to temperature changes. Ideal for high humidity areas (eg freezer). Disadvantage: may deform under weight.
- 🔹 Stainless steel —maximum strength and hygiene. Used in professional refrigerators. Disadvantage: more difficult to process (you need a grinder or metal scissors).
- 🔹 Wood (beech, oak) - environmentally friendly, suitable for retro refrigerators. Impregnation with food varnish is required! Minus: may swell from moisture.
- 🔹 Aluminum profile —light, does not rust, holds its shape well. Often used for shelf frames.
For most household refrigerators, the optimal choice would be tempered glass 6-8 mm thick or food grade plastic 10-12 mm. These materials combine strength, hygiene and ease of processing. If you need a shelf for the freezer, give preference to plastic - it will not burst when frozen, unlike glass.
2. Tools and consumables: complete list
Before you start work, prepare everything you need. Most tools can be found in a home workshop, but some will have to be purchased. Here minimum set:
| Category | Tools/materials | Notes |
|---|---|---|
| Measurement and marking | Roulette, square, marker, ruler | For accuracy, use a metal tape measure |
| Cutting material | Jigsaw (for plastic/wood), glass cutter (for glass), metal scissors | For glass, it is better to order cutting in a workshop |
| Edge processing | Sandpaper (grain 120–240), file, grinder | Mandatory for glass and metal! |
| Fastening | Self-tapping screws, plastic dowels, silicone sealant, glue for plastic | For glass - special holders with rubber gaskets |
| Additionally | Gloves, goggles, dust mask | Do not neglect technology safety! |
If you work with glass, be sure to buy shelf holders —they fix the glass on the sides and prevent slipping. For plastic shelves, ordinary self-tapping screws with a press washer are suitable. For metal, you will need metal drills and taps for cutting threads (if you plan to mount the shelf with bolts).
⚠️ Attention: When working with glass, use diamond glass cutter and do not forget about gloves - even tempered glass can leave sharp crumbs. After cutting, be sure to sand the edges and check them for chips.
3. Taking measurements: how not to make a mistake with dimensions?
An error in measurements is the most common reason why homemade shelves do not fit. To avoid this, follow our algorithm:
- Measure the internal width of the refrigerator in three places: at the back wall, in the middle and at the door. Often these values differ by 2–5 mm due to the curvature of the walls.
- Determine the depth of the shelf. It should be 1–2 cm less than the depth of the refrigerator so that the shelf can be pulled out freely.
- Consider the height. If the shelf will be located above the vegetable boxes, leave a gap of at least 3–5 cm for air circulation.
- Check the location of the fasteners. In some models (for example, Samsung RB30J3000WW), the shelves are fixed on special grooves - they also need to be measured.
Professional advice: make cardboard template in full size and check how it fits into the refrigerator. This will help avoid mistakes when cutting the base material. Do not forget that in the freezer the shelves must withstand load up to 15–20 kg/m² (the weight of frozen foods increases!).

4. Step-by-step instructions: how to make a glass shelf?
Glass shelves look stylish and are easy to clean, but require careful manufacturing. Here step-by-step algorithm:
- Marking. Transfer the dimensions from the template to the glass using a marker. For cutting, use masking tape - it will prevent chipping.
- Cutting. Run the glass cutter along the line with even pressure. Then gently tap the bottom of the glass - it should break along the cut line.
- Treating the edges. Clamp the glass in a vice (through a rag!) and process the edges with sandpaper or a diamond file. The edges should be smooth to the touch.
- Installing holders. Glue silicone or plastic holders to the corners of the shelf. They will prevent slipping and soften shocks when closing the door.
- Mounting in the refrigerator. Insert the shelf into the grooves or secure it with screws (if the mount is side-mounted). Check stability by lightly pressing on the edge.
If you are not confident in your glass cutting skills, it is better to order this service in a workshop - the cost usually does not exceed 300–500 rubles per sheet. The main thing is to provide exact dimensions and indicate that the glass should be tempered (regular glass can burst due to temperature changes).
5. Plastic shelf: quickly and without special tools
Plastic is the simplest material for making a shelf. Food grade polypropylene or PET with a thickness of 10–12 mm is suitable. It can be cut with a regular jigsaw or even a hacksaw. Here's how to make a shelf in 1 hour:
- Choice of plastic. Buy a sheet at a hardware store (for example, Polygal or Plastilux). Make sure it is marked as Food grade.
- Cutting. Mark the sheet, secure it with clamps and carefully cut it out jigsaw For an even cut, use the guide bar.
- Treating the edges. Smooth the edges with sandpaper and melt them with a construction hair dryer - this will remove burrs and make the shelf safe.
- Fastening. Screw the shelf to the side walls of the refrigerator using self-tapping screws with a press washer. Pre-drill holes of a slightly smaller diameter so that the plastic does not crack.
For the freezer, choose plastic with frost-resistant markings (usually this is indicated on the package). If the shelf will be used for heavy products (for example, jars of pickles), reinforce it with aluminum corners glued with epoxy glue.
⚠️ Attention: Do not use PVC or foam plastic for shelves - these materials emit harmful substances at low temperatures and can crumble over time.
6. Metal shelf: strength and durability
Metal shelves are suitable for refrigerators with intensive use (for example, in a cafe or a large family). It is best to use stainless steel 1–1.5 mm thick or an aluminum sheet of 2–3 mm. The manufacturing process is more complicated, but the result is worth it:
- Marking and cutting. Apply the outline of the shelf to the metal, then cut it out with a grinder or metal scissors. Clean the edges with a file.
- Drilling holes. Drill holes for fastening (the diameter is 0.5 mm less than the diameter of the screws). If the shelf has sides, bend the edges using a vice.
- Processing. Polish the shelf with a grinder or sandpaper. For stainless steel, use paste GOI —it will add shine.
- Fastening. Fix the shelf with self-tapping screws with rubber washers (they will prevent corrosion). For additional strength, you can weld the corners.
If you are making a shelf for the freezer, pay attention to aluminum profile —it does not rust and tolerates low temperatures well. For aesthetics, you can paint the shelf with powder paint (for example, white gloss). RAL 9003 - white gloss).
How to avoid corrosion of a metal shelf?
To prevent a metal shelf from rusting, treat it after grinding with an anti-corrosion compound (for example, Zinkor). You can also cover the shelf with a thin layer of food-grade silicone - this will protect it from moisture and make it easier to clean.
7. Installation and testing: how to check reliability?
After manufacturing the shelf, it must be properly installed and tested. Follow these recommendations:
- 🔧 Check the horizontal position. Put a level on the shelf - if there is a skew, place a silicone gasket under one edge.
- 🔧 Load test. Place a load weighing 10-15 kg (for example, a bag of salt or bottles of water) on the shelf. If the shelf sag, reinforce it with additional stiffening ribs.
- 🔧 Checking the fastenings. Close the refrigerator door sharply - the shelf should not budge. If the fastenings are unreliable, use longer screws or additional fasteners.
- 🔧 Hygienic. Wipe the shelf with a vinegar solution (1 tablespoon per 1 liter of water) - this will remove traces of processing and prepare the surface for use.
If the shelf is intended for the freezer, leave it for 12 hours at a temperature of −18°C, and then check for cracks or deformations. Plastic shelves in the freezer may narrow by 1-2 mm - take this into account when manufacturing.
8. Caring for a homemade shelf: how to extend its service life?
To ensure that the shelf serves for many years, follow simple care rules:
- 🧼 Glass shelves wash with warm water and liquid detergent. Avoid abrasive sponges - they scratch the surface.
- 🧼 Plastic shelves wipe with a soft cloth with a soda solution (1 teaspoon per 1 liter of water). Do not use chlorine - it destroys plastic.
- 🧼 Metal shelves clean with a vinegar solution, then wipe dry. For shine, you can use stainless steel polish.
- 🧼 Wooden shelves treat them with edible oil (for example, linseed) once a month - this will prevent cracking.
If cracks or chips appear on the shelf, do not use it to store food - this can be dangerous. Plastic and wooden shelves wear out over time, so check them for strength every 2-3 years.
⚠️ Attention: If an unpleasant odor appears in the refrigerator, check your homemade shelves - sometimes the cause is microcracks in which bacteria accumulate. In this case, it is better to replace the shelf.
Frequently asked questions
Is it possible to make a shelf for a refrigerator from ordinary glass?
No, ordinary glass is not suitable - it can burst from temperature changes or mechanical stress. Use only tempered glass at least 6 mm thick. If you are not sure, order cutting in a workshop marked “for the refrigerator.”
How to attach a shelf if there are no grooves in the refrigerator?
There are several ways:
- 🔹 Install side holders on self-tapping screws (furniture corners are suitable).
- 🔹 Use silicone glue for plastic or glass shelves (but this is less reliable).
- 🔹 Drill holes in the walls of the refrigerator and secure the shelf with bolts and rubber washers.
The main thing is not to damage the freon line (it runs along the back wall)!
What load can a homemade shelf withstand?
It depends on the material and design:
- 🔹 Glass (8 mm) - up to 20 kg/m².
- 🔹 Plastic (12 mm) - up to 10-12 kg/m².
- 🔹 Stainless steel (1.5 mm) —up to 30 kg/m².
For comparison: a standard shelf in the refrigerator Atlant is designed for 15–18 kg. Do not store heavy pots or cans of preserves on homemade shelves - better distribute the load.
What to do if the shelf does not fit into the refrigerator?
Possible reasons and solutions:
- 🔹 Inaccurate measurements - sharpen the edges with sandpaper or a file.
- 🔹 Deformation of the material (especially for plastic) - warm the shelf with a hairdryer and straighten it under a load.
- 🔹 Fasteners get in the way -check if the shelf does not rest against the guides or door seal.
If the problem is width, you can make a shelf pull-out - use furniture guides for this.
Can a plastic shelf be painted?
Yes, but only food paint (for example, water-based acrylic). Before painting, degrease the surface with alcohol and apply a plastic primer. It is better to paint in 2 layers and dry for 24 hours. Do not use automotive enamels or nitro paints - they are toxic!
