Direct answer
A shower leak can come from the water supply, waste, screen seals or waterproofing. Timing is the clue: leakage only while water hits a surface differs from leakage that continues after use.
What can cause the problem or change the decision
| Possible factor | What to record safely |
|---|---|
| Failed screen or silicone joint | Stop using the shower |
| Waste or trap leak | Dry and observe the leak timing |
| Concealed supply leak | Check the room behind or below |
| Failed waterproofing membrane | Do not mask dampness with new sealant |
