Hello everyone, I am planning to use several Billy shelves from IKEA in my bathroom to create additional storage space. However, since the bathroom tends to be quite humid due to the bathtub and shower, I am concerned about the durability of the shelves. My main question is: How can I effectively protect Billy shelves from the typical moisture found in bathrooms? What measures and materials would you recommend to prevent the shelves from swelling or developing mold? I am considering both preventive coatings and special sealants but would appreciate practical advice and long-lasting solutions. Thanks for sharing your experiences!
The most important thing is not to place shelves directly against damp walls. A waterproof coating or a special bathtub paint on the wood provides good protection. Additionally, mounting the shelves so they allow air circulation and regularly ventilating the room are very helpful.
Hello Tumanuel, your concerns are very valid. BILLY shelves are made of particleboard, which does not handle moisture well. One of my proven methods is to thoroughly sand the shelves first and then seal them with multiple coats of polyurethane-based varnish. This makes the surface water-resistant. Additionally, I recommend giving extra protection to the undersides and back panels, as these areas often absorb moisture. You can also apply silicone seals at the contact points with the wall and floor. If possible, control the indoor humidity through ventilation or a dehumidifier – this will significantly extend the lifespan.

One of my tested methods is to sand the shelves thoroughly first and then seal them with a multi-layer polyurethane-based varnish.Thanks for the tip, gregto. Do you use a specific varnish that can be bought at a hardware store? And how many layers of varnish are optimal? Is that enough to resist splashing water directly from the sink, or should I consider additional protective measures?
The answers so far are solid. Additionally, I recommend never placing the shelf directly against walls exposed to moisture. Use small spacers or felt-coated feet to prevent moisture from seeping in from below. You can also apply water-resistant membranes or special sealing tape strips to the back. These create a barrier against moisture. Ideally, complement this setup with good ventilation in the bathroom—this allows moisture to escape more quickly. If you want to use paint, apply several thin layers with sufficient drying time between each coat.
