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.

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.

  And if both shower heads are on at the same time, they possibly won't have as good a flow as just one, unless the place has very good water pressure.

  @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.

BUT , in the US , regulations require that these shut-off valves leak, so if you have a head turned off ,it will still drip. We usually have both on at the same time. It did take a couple trips to the "big box" store and one trip to the plumbing store to find out that these shut-off are required to leak ( in US).

I have two heads in the master, I don't remember any charge but I guess there was. You just add inexpensive shut-offs on each head , works fine.
