Hello everyone,
I recently encountered an issue with my IKEA Kallax shelving unit, which is placed in the bathroom. After a minor water leak that I noticed quite late, several cracks have appeared in the side panels made of particleboard. The cracks are mostly along the edges and seem to be where the material has swollen somewhat.
I’m interested in how you assess such cracking on a Kallax unit after water damage – are these typical weak points for this type of furniture? Can the damage be repaired, or is it usually irreparable and requires replacement?
Also, are there ways to protect the shelving unit to prevent similar damage in humid rooms like bathrooms in the future?
I would appreciate any experiences and tips, including recommendations for suitable repair methods or specific products. Thank you in advance!

The issue of cracking in Kallax and similar shelving units after water damage mainly stems from the material used – usually particleboard with a decorative laminate layer. When moisture enters due to a water leak, the material swells and the adhesive bonds break down, leading to visible cracks.
These cracks often appear at the vulnerable edges and joints, where the structural strength is already limited. Whether repairs are worthwhile depends on the extent of the damage: small cracks can be fairly well fixed using wood filler or specialized repair kits. It is important to treat the wood afterward with a water-repellent sealant.
For more severe damage or if the material has considerably warped, replacement is generally advisable.
I would be interested to know how long the water leak lasted and whether the shelf was placed directly on the floor or on legs, to better assess how deep the damage might be. Was the unit completely dried out?

I’m curious how long the water leak went unnoticed and whether the shelf was placed directly on the floor or on feet,The leak apparently went unnoticed for about 2-3 days and was caused by a faulty seal on the washing machine. The shelf is standing directly on the tiled floor, with no feet or supports underneath. After discovering the leak, the shelf was soaked. I tried to dry it, but the damage only became visible later.
Has anyone experienced whether raising the shelf on a base or plinth to create a gap from the floor would provide significantly better protection? Or would sealing the surface be more effective?
After such a prolonged humidification phase, the shelf practically faces a structural issue. The water that dripped onto the floor and can collect at the edges of the particle boards seeps into the adhesive joints between the boards.
Yes, a base made of waterproof material can help keep direct moisture away from the floor and thus reduce swelling. Even better are plastic feet or a specially impregnated underlay.
Regarding sealing: It is advisable to treat the exposed cut edges and edge seals with acrylic paint or a special wood protective varnish. Sealing only the surface is not enough, as the cut edges are particularly vulnerable.
If you want to tackle this yourself, I recommend first drying with good air circulation, then sanding and repairing the edges, followed by applying several layers of protective varnish. It may also help to completely disassemble the shelf, if possible.
Have you checked whether the shelf is still stable or if the joints are already loose?

Should I remove the back panel completely and reattach it? Or would it be better to try stabilizing the surface with wood filler and sealant?
