We've got one possibly a bit smaller in our downstairs bath. I call it "the world's smallest shower". The outer width dimension is 31". I'm still getting the hang of "nominal dimensions". It feels very closed in, hard on the elbows. That said, I've showered in there when I was 9 months pregnant. My husband and I have showered in there together ... that was an experience in togetherness :lol. Ours feels dark and confining, a bit more "openness" would be great. The left side has a full-height wall between it and the vanity, I've considered putting a "transom" of glass block above the stall to make it feel more open.
