This model seems to be the largest we can go with, although the model size is 34" it requires more space for install estimate an additional 4" in either direction. Plumber also recommends perfectly plumb walls for install otherwise the doors will not function properly.
THIS PANEL IS A DIVERTER ONLY - INSTALLATION WILL REQUIRE THERMOSTATIC CONTROL VALVE WITH TEMP AND WATER CONTROL HANDEL.
