It depends on the cause. A sudden pipe or waste failure may be covered, while old grout, failed sealant or poor maintenance is less likely to be.

Where do shower leaks come from?

• Split silicone sealant.
• Cracked grout or loose tiles.
• A moving shower tray.
• A leaking waste connection or concealed pipe.

Stopping water getting behind the shower

• Replace failed sealant promptly.
• Repair loose tiles and damaged grout.
• Investigate staining on the ceiling below.
• If resealing does not solve the problem, check the waste and pipework.

The cause of the leak matters

The cause matters. Sudden plumbing failure and gradual deterioration can lead to different outcomes, even when the visible damage looks the same.
