Hello everyone,
I am currently considering whether the popular IKEA Kallax shelving unit can be modified to be used as a built-in cabinet in a niche or wall opening. Specifically, I am interested in which structural adjustments are necessary to install the Kallax securely and precisely without losing its functionality.
Does anyone have experience with this or can offer tips on fastening, surface treatment, or possible modifications? I am also concerned about aspects such as load-bearing capacity, potential reinforcements, and the possible integration of doors or sliding doors.
Thank you in advance!

For optimal stability, at least three support points per shelf should be used.That's exactly what I wanted to say. More than two fixings per shelf are necessary; otherwise, it tends to wobble.
Hello Lisfra,
Allow me to share a practical tip from my experience: if you want to use the Kallax as a built-in cabinet and care about the appearance, don’t skip the surface treatment. It’s best to sand the shelf lightly with fine sandpaper first, then apply a suitable paint or wood preservative.
Make sure the color matches the rest of the wall design—this will create a visually harmonious built-in.
You can also seal the joints between the shelf and the wall with foam tape or acrylic sealant to reduce dust accumulation and hide any small gaps.
This not only improves the look but also enhances the durability of the furniture piece.

That’s brilliant! 🙂 I combined the Kallax as a built-in unit in my corner and personalized it completely with some paint and new handles. I also added doors, which was really easy. I can only recommend giving it a try and doing it yourself!

Maybe someone has specific tips on types of door hinges or modifying the back panel.
Hello Lisfra,
Regarding your questions:
1. Attaching doors: I usually use small surface-mounted hinges that are fixed directly to the outer edge of the shelving unit and the door. This allows the doors to open and close without pressing against the frame. Alternatively, concealed hinges can also be used, but you need to drill the holes very precisely.
2. Back panel: The original Kallax back panel is thin and not load-bearing. If you want a more stable built-in structure, you can safely remove it and replace it with a new back panel made of 6–8 mm (1/4–5/16 inch) plywood. You can then fix this with screws or brackets and even use it to hang the unit on the wall.
In summary: Replacing the back panel is definitely recommended for longer-lasting stability when built in.

Without a sturdy back panel, the shelving unit becomes unstable quickly, especially with a height of 220 cm (87 inches). A simple back panel made of plywood or MDF, ideally glued and screwed, is sufficient.
