Laurie Plattes The shower area was originally a standard tub/shower. I don't have the exact dimensions at hand but I know this room was 60 - 66" wide. The tiles are 12 x 24 running the long way in the space.The center and ends of the vanity were tucked back to create more floor space. Also, the faucets are wall mount which allows you to use a shallower vanity so the floor space feels more open.
