Shower Valve Rough-In Depth Tolerance
Category: infrastructure
The precise installation depth range allowed for mounting a plumbing valve body inside a finished stud wall cavity.
Plumbing valves feature a plastic protective guard ring marking the minimum and maximum allowable finished wall lines. If the plumber mounts the valve too deep or too shallow relative to the future thickness of the cement board, thinset, and tile, the finish trim kit handles cannot latch.
Common Examples
- The plumber adjusted the framing blocking to ensure the shower valve rough-in depth accommodated our thick handmade tile slabs.
- Forgetting to calculate the thickness of a custom tile backsplash can push your valve trim entirely out of its legal installation tolerance.
