Moisture resistant PU trim is the right answer for bathrooms, kitchens, and any other humid environment. The PU material is naturally moisture resistant (closed-cell structure), and the trim handles the humidity without swelling, cracking, or rotting.
The most common moisture resistant PU trim is a cove cornice in a bathroom. A small cove profile, 80 to 120 millimeters of curve, applied to the ceiling line. The cove is the most common bathroom cornice because the curved profile doesn't collect dust and the simple shape is easy to clean.
A second common moisture resistant PU trim is a waterproof baseboard in a bathroom or kitchen. A 100 to 150 millimeter baseboard, with a cove or stepped profile, applied to the bottom of the wall. The baseboard handles splashes and humidity without damage.
A third common moisture resistant PU trim is a chair rail in a dining room or a kitchen. A 60 to 100 millimeter chair rail, with a cove or stepped profile, applied to the wall at the right height. The chair rail handles the humidity and the impact from chair backs.
A fourth common moisture resistant PU trim is a panel molding in a bathroom or kitchen wainscot. A 30 to 50 millimeter flat or stepped strip, applied to the wall in a panel grid. The panel molding handles the humidity without damage.
For sourcing, moisture resistant PU trim is a stock product at most factories. The factory offers a range of standard moisture resistant profiles and sizes, with quick lead times and competitive pricing.
A practical install note: the trim in a wet area should be installed with a waterproof adhesive and sealed with a waterproof caulk at all joints. The caulk should be a kitchen-and-bath formulation with mildewcide, not a standard painter's caulk. The joints are the most vulnerable points in a wet area, and the caulk is the protection.
A practical note on the finish. The trim in a wet area should be finished with a moisture-resistant enamel, not a flat ceiling paint. The enamel resists the humidity and the occasional wipe-down; the flat paint will mark and may peel.
