American Standard Temperature Control Rough-In Valve With Integral Diverter - AMS-R116SS

The R116SS is the rough-in valve body only, ordered as a rough-in kit under model number R116SS. It's the temperature control valve with an integral diverter that gets set in the wall during rough-in. It ships with no finish, because the body is buried behind the wall, so the handle, escutcheon and spout or shower trim are a separate order in whatever finish the job calls for.

That's what the integral diverter is for. The valve sets the temperature and the built-in diverter sends the water to one outlet or the other, so you get both outlets controlled from a single valve body instead of adding a separate wall diverter. The matching trim determines how the diverter is operated at the wall.

Yes. The valve has a Hot Limit Safety Stop, which caps how far toward hot the handle can be turned so someone can't accidentally draw full-temperature water. It's set at installation to suit the water heater temperature on that building.

The body is brass and the working cartridge is a ceramic disc type, which is the wear surface that decides whether a valve starts dripping. Ceramic discs hold up far better than rubber-seated designs under heavy daily use, and brass gives you a solid base for repeated trim changes over the life of the wall.

That's the practical advantage of buying the R116SS as a bare rough-in. Because it ships unfinished and the trim is separate, you can rough in the same valve across every bath in a property and pick different American Standard trim finishes per unit, or swap trim years later on a remodel without opening the wall again.

No separate mixer is needed for temperature setting. The R116SS is itself the temperature control valve for the shower or tub, with the Hot Limit Safety Stop limiting the hot side. Whether your local code additionally requires a specific anti-scald listing for the fixture type should be confirmed against the plans for that job.
