Moen produces a variety of Roman Tub rough-in valves. The handle assembly and interior handle mechanisms are not the same for each valve and they are not interchangeable. In order to service your Roman Tub, we recommend that you identify your handle assembly and handle mechanism. This article will walk your through the process.

Preparation: The water supply shut off valves must be turned off- see article How to Turn Off the Water Supply to the Faucet .
