We are getting ready to redo a second bathroom in which the shower is against an exterior wall with a window. The window is vinyl but the trim and sill are wood. It currently looks in decent shape with a little cracking, but I was wondering if over time the constant water exposure will create moisture problems around and under the window. It was suggested that we replace the window with glass block, which I imagine could be sealed against moisture and also provide a little privacy. Unfortunately the cost is putting us over our budget. Is there a better solution that may be cheaper? Because it's not our main bath the shower isn't used as frequently.
