I am building my own house and finishing up my rough-in. For my stand-up shower (no tub), instead of buying a brand-name shower kit (Moen, American Standard, etc) I want to install a pressure balancing valve, stub out with ball valves that turn hot and cold on/off, and use a T to go up to the shower head. The finish look will be very simple and industrial-looking. Can someone describe how to plumb this? Or is there a schematic/diagram somewhere that would explain it?
