Start with the source.
Shower detection can investigate moisture behind walls, around a base or in the room below. The timing matters: a leak only during use can suggest a different source from moisture that appears when the shower has not been used.
What an assessment may involve
A contractor may inspect accessible fittings and test the supply, drain or enclosure separately. Controlled testing helps avoid confusing splash water with a pipe or waterproofing failure.
Before you arrange a visit
Explain whether the leak occurs during use, after use or continuously. Note any recent recaulking, tile work or valve replacement. Avoid repeatedly running the shower to reproduce a leak that is actively damaging the property.
Detection, access and repair
Fresh caulk is not a universal solution. A supply leak, failed pan, drain connection and waterproofing problem require different work. Ask what has been tested and what remains uncertain.
Questions about shower leak detection
Can grout or caulk cause a shower leak?
Gaps can allow water into vulnerable areas, but visible damage does not establish the entire cause. Plumbing and waterproofing may also need checking.
Can the leak come from behind the wall?
Yes. A supply connection or valve may be concealed. Access and testing depend on the shower layout.
Does a ceiling stain identify the exact source?
No. Water may travel before it becomes visible. The shower, nearby plumbing and other possible sources should be considered.
