What to do about a Wood window in shower?

A vinyl roller blind. When you search look for ones that say "light filtering".

I painted mine with high gloss paint. Condensation just rolls off and easy to dry after each shower.

Paint with enamel paint, I used RustOleum. Buy static cling privacy film to put on the glass. It applies with water, no sticky residue if you want to remove it.

Hang a shower curtain over it. Open when done showering...closed while showering.
