If you have less than five feet of clearance but still want a bathtub, don't despair. Plenty of manufacturers makes tubs in sizes small than 60". Also, a glass panel can block spray from the shower, and take up a lot less visual space than a shower curtain and rod.
So we are doing this shower - except plexiglass. walls are grey and the shower is this dark charcoal the color of the doors. then exposed pipe with lush large white curtains around the shower - inexpensive way to get a shower door!!!!
