We had a rear bath on our last TT that the missus really liked - all the functions in one cozy room. Frankly it was a bit too cozy for me: some interesting yoga positions assumed when drying off after a shower! I can relate to Superman changing his clothes in a phone booth!
Newer FW has a split bath which I love as finally enough room to towel off by moving my arms. She really doesn't like it though & has fondly mentioned the old bath layout several times. The toilet room is tight but no less legroom than the rear bath. Guess you can't please everyone (or at least two people who are vastly different in scale)
