Unfortunately, any type
of paint will ultimately fail in a high-moisture area such as a shower. To
achieve the longest-lasting finish, sand to bare wood and apply an oil-based
primer followed by two coats of alkyd paint. If and when you replace the
window, vinyl would be a better choice than wood because vinyl never needs to be
painted.

Oil paint huh? Seems like a lot of work-Ill probably just have someone else do it or something/ thanks for the respinde though!

Not a problem at all.
