So I'm building a new bathroom and have decided I want 3 things in the shower/tub. A tub filler, a shower head, and 1 hand-held head. I found that Grohe makes a Retro-fit system which would be supplied by a normal single shower head off a pressure balance valve. It comes with an external diverter. I'm curious if this is a smart way to go or should I just run a separate in wall diverter? Also I've never had a thermostatic control valve and I know I like to take much hotter showers then my wife, does this present a problem?
Thanks for your help.
