Below, you can find how to protect wooden bathroom doors from water:
Preparation: Start by cleaning the door thoroughly with mild soap and drying it completely. Sand lightly with a 220 grit sandpaper, including the bottom, edges and top to remove old finish and open wood pores.
Fill Cracks: Then, fill any cracks or gaps with wood filler or epoxy, then tape off hardware and glass if present.
Prime: After this, apply a high quality waterproof wood primer on all the sides. Let dry for about 4 to 6 hours.
Seal: Brush on 2 to 3 coats of polyurethane varnish, waiting 4 hours between coats. Then, sand lightly between for smoothness.
Edges/Bottoms: Use silicone caulk or weatherstripping on frame gaps and the bottom edge. Add a drip edge if needed.
Finish: Finish by topping it off with waterproof enamel paint or marine grade varnish for extra protection. You should reapply once every year.
Apart from all this, run an exhaust fan for like 20 to 30 minutes post showers, wipe the door dry after usage and use marine plywood doors or PVC overlays if your bathroom is prone to high moisture. I will end my answer here. I hope this will be useful for you.
