Use this kind of aluminum door for bathroom. Will last longer and more sturdy compared to pvc or plywood door.
Usually, the toilet plywood door will get swollen if not painted at the bottom of the door. You can try to put your phone camera under the door to see if it is painted or not.

erm, i think you can opt for ones without the glass panel...

u can use ACP panel instead of frosted glass.
imo this aluminium door is the best for toilet.

If you want to waterproof your door you need to take out your door, completely cover your door with paint except the door knob, then apply 3 layer of polyurethane paint on the entire door except the door knob

This is the most cost effective but time consuming way of your don't want to change the door the polyurethane can provide hard film to resist scratches, and waterproof your door once it is cured even if it is a cheap door
