Curbless Walk-In Showers
This is an example of a curbless shower, built by Steve White (owner of SRW Contracting, Inc.) in the greater Pittsburgh area. You can achieve results similar to his on your own with the help of Steve's bathroom remodeling courses he has available on his website at www.bathroomremodelingteacher.com/learn.
Possibly add shower door later, use a curtain for seniors
