ROHL’s 3/4-inch Thermostatic Shower Rough is compatible with all ROHL Bath Series trim plates. The rough provides clients with the flexibility to upgrade the style and functionality of their shower without altering the plumbing behind the wall. Each rough is complete with a unique mud guard with minimum and maximum wall-depth indications for ease of installation, ROHL notes. Service-stop check valves also are included. Flow rate for the “universal” rough is 12 gpm at 60 psi. This rough is temperature-control only. Both the volume-control rough valves and trim plates must be ordered separately.
