Hi, We have had a complete nightmare with our shower for the past year. It keeps leaking, with water going through the ceiling into the living room. We have had to cut a hole in the ceiling, so we can see the waste outlet. It is bone dry but someone come out and said this was the problem and replaced it for £200. sadly, it was not the problem and it had contained to leak but it is definitely not leaking through the outlet. We have re sealed all around the shower tray and grouted again, but still leaking. We have tried a few tests. For example, it only leaks if someone is in the tray with shower running. We have tried people coming round, but they charge and say they know what the issue is, but then it just leaks again! I do have a video of the leak, While the shower is running, if this is helpful but it’s too large to attach here. Any help or support will be greatly appreciated!
