Hello everyone,
I am planning to place a KALLAX shelving unit from IKEA in my bathroom to store towels, toiletries, and a few decorative items. Since bathrooms generally have much higher humidity levels—especially after showering or bathing—I am concerned whether the high moisture and possible condensation on the shelves could cause problems.
Specifically, I am interested to know if the KALLAX furniture, made from typical engineered wood materials (chipboard, MDF, or similar), can be damaged by prolonged exposure to increased humidity, for example through swelling, warping, or material deformation.
Does anyone have experience with this or know if such furniture can be safely used in a bathroom? If so, are there specific precautions to take, such as maintaining distance from the walls, increasing ventilation frequency, or applying protective treatments?
I look forward to well-informed answers and advice on using KALLAX units in high-humidity environments!

Moisture is the main enemy.I completely agree – I used to have a shelf in the bathroom that I pushed too close to the bathtub. After some time, the bottom shelf visibly swollen. That really annoyed me because I hadn’t considered it beforehand.
Since then, I make sure there is air circulation and I ventilate the room every 2 hours on purpose. Maybe that will help you too.
Hello everyone 😄,
even if it’s just a shelf: the bathroom is actually not the most suitable environment for wood-based materials. Due to the constant humidity, the KALLAX can sometimes start to “cook” – that is, swell and splinter.
But don’t worry! 🙂 With a little distance from the wall and regular ventilation, it usually stays in good shape.
Oh, and a bit of DIY protective coating with clear varnish can work wonders. Believe me, I’ve treated my KALLAX with a moisture-resistant finish before – it looked great afterward and lasted longer.

Hello benlo,
to answer your question more precisely: The KALLAX shelving unit is mostly made of particleboard with a melamine coating. Particleboard is generally vulnerable to moisture because the wood fibers can absorb water and swell.
The melamine coating provides surface protection against splashes and light moisture, but it is not completely waterproof. Therefore, in consistently high humidity environments—such as bathrooms after bathing or showering—moisture can penetrate the cut edges or uncoated areas and cause damage.
This process is usually gradual: initially, small swellings appear; later, edges may crack or the material may deform.
Important points are:
- Do not place the shelving unit directly against a frequently damp wall
- Ventilate regularly: at least 15 minutes of cross-ventilation after bathing
- Leave a gap of about 5 cm (2 inches) between the unit and the wall for air circulation
- If possible, protect the edges with water-repellent products (e.g., clear varnish, furniture wax)
Thus, a KALLAX unit can be used in a bathroom if certain precautions are taken. For wet rooms, specially designed solid wood furniture with varnish or plastic materials is usually more suitable.
I hope this helps!

Particleboard is generally susceptible to moisture because the wood fibers can absorb water and swell as a result.To be precise: particleboard swells measurably when it absorbs water. Melamine coatings provide primary protection but are not permanently waterproof. With consistently high humidity and frequent water exposure, diffusion at cut edges and joints causes expansion and thus deformation.
Therefore, the suitability of KALLAX for damp environments is limited, especially in bathrooms without perfect ventilation and with strongly fluctuating relative humidity.
Recommendation: maintain at least 5 cm (2 inches) distance from the wall plus thorough ventilation by regularly airing out after moisture exposure. Optionally, cut edges can be additionally treated with a water-repellent finish.
More durable solutions in the long term are furniture options with coatings that provide specific moisture protection or versions made from water-resistant materials.
