Hello everyone,
I am currently planning the interior of my tiny house and considering using the Kallax shelving system from IKEA as a flexible storage solution. Due to the limited space in a tiny house, storage needs to be multifunctional, sturdy, and as lightweight as possible. I already have some rough ideas but lack practical experience, especially regarding
- how stable the Kallax can be under heavier loads in a tiny house
- whether it is suitable for wall mounting (e.g., for travel or better support)
- if other users in the tiny house or camper van community have modified or reinforced the Kallax afterward
- how the material and workmanship perform with fluctuating humidity and temperature
Can anyone provide specific tips or share their experiences with how Kallax holds up in such a tight, mobile environment? What modifications have proven useful? And are there lighter alternatives to Kallax that remain modular, which you know of?
Thanks in advance for your help!

Hello jimmeo,
I’d like to share some of my experiences with the Kallax unit in a tiny house, as I installed one myself some time ago:
1. Stability: While the standard Kallax is sturdy, it is not designed for continuous heavy loads under mobile conditions. Therefore, I recommend adding extra reinforcement, especially at the bottom, using strong MDF panels and screw fasteners. This prevents sagging and increases safety.
2. Mounting: Securely fastening it to solid walls or frame elements is essential. I also added angle brackets to the shelf corners to maximize stability while on the move.
3. Moisture and temperature: Kallax is made from wood fiberboard with a melamine coating. It resists moisture fairly well, but over time, corners can swell if exposed to too much dampness. Good ventilation and regular inspection are important.
4. Modifications: I partially removed the back panel to create cable channels. Additionally, I installed doors to close off the storage space.
If you want lighter alternatives, consider shelving systems made of aluminum or plastic. These are lighter but often less modular and more expensive.
In summary: Kallax is quite practical but requires reinforcement and secure anchoring — with that, it can be very effective.
If you have specific questions, I’m happy to help.

Kallax is sturdy but not designed for continuous heavy loads under mobile conditions.I agree with this and would like to add:
- Kallax is made from medium-density fiberboard (MDF/HDF) with a melamine resin coating, which is resistant to scratches and moisture but can crack at the joints under strong vibrations or heavy loads.
- If the tiny house is mobile (e.g., on wheels), the main fastening should be done by gluing and screwing to a stable frame or wall. Simple dowel connections alone are not suitable for this purpose.
- Using brackets and securing the shelves with plywood panels on the back greatly improves overall stability.
- For weight management, I recommend storing heavy items such as tools or supplies in the lower compartments to ensure stability and prevent tipping.
- Melamine coatings are generally sufficient for changes in humidity and temperature, but for long-term use, a waterproof impregnation or restricting Kallax to well-ventilated areas is advisable.
A combination of professional installation and careful consideration of load makes Kallax quite suitable for use in tiny houses.
