I have an old house where all the windows were centered on the wall including my 6x9 only bathroom. It is 39"Hx26"W and juts 10" into the shower enclosure. I am going to remodel and want to fix the issue so I can put glass doors on the tub. Is it important to have a window in a tiny bathroom? I'd like to close it in but I'm afraid it would devalue the house, besides the exterior of the house is stone so it may be difficult. Ideas?
