We have to remove the old tub surround in our bathroom and install new tub surround. I have had a slower curtain on the window wall to protect window frame but I want to do something different with new tub surround. The window is not a large one - upper and lower which raises to open and close, size about 2 l/2 foot wide and 4 foot long. It faces the east and is the only source of natural light. I don't want to have to use a big curtain again but want to have the light. The bathroom is long and narrow, 6 ft. by l2 ft. including the tub at far end opposite entry door. Cannot afford a lot of remodeling to do this but it has been so UGLY I want to try to have an attractive bathroom. HELP? And thanks.
