Shower will be 4x5 and probably have a seat of some sort ... alcove with glass doors on front side. I think I can keep wife limited to a handheld spray on a rail that doubles as a shower head, another handheld spray near the seat (leg shaving I am told), and a rain shower head ... trying to avoid the electronic control approach, if possible. Three separate valve, one multi head valve to share between main shower handheld and the rainshower head, then split out the leg shaving one separately? I figure this has been a huge discussion topic on site for the last 10 years or so! I would really appreciate thoughts and comments on what everyone think works well and what is just glitz and glammer ... Thanks!!
