Doors for Bathrooms and Humid Rooms: What to Know Before Buying
Doors for a bathroom are often picked "like all the others" and a year or two later the owner wonders why the bottom edge swelled or warped. The reason is simple: humidity in a bathroom or laundry room is consistently higher than in living rooms, and the door needs to be ready for that from the start. Three things worth checking.
1. Finish
PVC film creates a barrier on the surface and holds up better against regular humidity and wiping down splashes or condensation. Painted doors can go in a bathroom too, but with a quality, even coating and no direct contact with water.
2. The bottom edge
This is the most vulnerable spot: it's in contact with a damp floor the longest. Aluminium edging around the perimeter protects the panel from swelling and chipping right there. Check it in a model's specs first, not just the colour or texture.
3. The gap at the bottom
The right gap between the door and the floor provides ventilation and keeps moisture from building up against the wood. That's an installation question, so agree on it with your installer ahead of time.
In short: for a bathroom, utility room or laundry, a door with PVC finish and aluminium edging around the panel is the most reliable. It will outlast a regular door there.
