Shower and bathroom leak detection involves identifying the source and extent of water infiltration behind, beneath, or around bathroom wet areas — without invasive demolition. It's distinct from general plumbing inspection because the problem is usually waterproofing failure rather than a pipe fault.
The challenge is that bathroom leaks are hidden. Water penetrates the grout and tile layer, saturates the substrate, and may travel laterally before surfacing — often in a room below or beside the wet area. Without mapping the leak accurately, a builder who tiles over a failed membrane is simply delaying the next failure.
