My bathroom in progress

Still need to coat the brown painted stuff with polyurethane (been trying to do that for WEEKS now), then install the frame around the mirrior. I held a board up in one of the pictures so you can get an idea. Also, need to touch up the blue paint where it got white on it and probably do another white paint coat (just because I'm slightly ocd and want it perfect--maybe that is why this project is going on three months now)
Any shower curtain ideas/tips?
