I'm working with a home builder to have two shower heads in a master bath shower. The builder proposes have two shower valves, one per head. Is this recommended/required or is the builder just trying to charge me more for another part?

    Where are the two heads going to go? Right next to each other? On adjacent walls? Rain head on the ceiling? I have two heads and two valves and I really wouldn't want it any other way.

    Some like it hot. Without two valves, co-ed showers won't be fun for one of you. One thing though, if an extra valve will require a larger pipe, it'll take longer to get hot in normal use. I've had two before (nothing beats it), but it was fed in 3/4s; almost took 5min to get hot. - "require" ? IMO, absolutely.

If you don't want both shower heads to be on at the same time everytime you take a shower, then yes you need 2 controls. If you don't care if both head are on, then one control will be fine.

    @JACK Shower-head shut off valves can cause cross-over problems (hot water flowing out of cold taps and vice versa). You're shutting off the flow downstream of the hot/cold mixing of the main shower cartridge. Think twice before installing this bullshit, especially if you live in a condo building.
