We've had a leaking shower for a number of weeks now.

Originally we thought it was the sealant around the tray. However, we have renewed this and am confident that there is no issue there, but the leak still persisted.

We then cut a hole in the plasterboard ceiling below. We can see the water dripping down the outside of the wall panels, but can't work out where it is coming from.

Next, we thought it was getting down the sides of the shower controls,, but these have now been completely sealed and the problem has not gone away.

The plumber wanted to cut an additional hole in the back of the stud wall that contained the shower itself, but the wife wouldn't let him rolleyes

She wants to rip the whole thing out and replace with new at a total cost of about £3.5k!banghead

Any other ideas as a last resport to try and find the source?

maybe do what the plumber is suggesting given he's the expert?

cut a hole in the plasterboard, locate the leak, fix the leak... don't spend £3.5k

The shower screen. We had one that leaked and the water went behind the sealant.

Get an inspection camera. Something like this... https://www.amazon.co.uk/Pancellent-Inspection-Wat...

Then you only need to drill a 10-15mm hole to have a look in the cavity. Making good a hole that size is easy, unless you have some patterned wall paper.

I've used a 20mm hole saw bit without the centre drill attached to effectively cut 20mm plugs from plasterboard walls before, you can then glue that back in with some no more nails and when set use a fine surface filler.

If you have a loft then sometimes you can attack the problem from above and with a camera get a view of the pipework into and out of the valve.

The water could be from anywhere! It might be as simple as a fitting which needs snugging up, a pin hole leak, from the waste etc etc. Where it shows and where it originates can be markedly different. Plumbing, gotta love it.

A new shower is no guarantee that it won't leak.

Stud walls are very easy to repair!
Provided the paint can be matched well enough.

If it's been leaking a while, I'd personally have it apart and treat with wood preserver, after it's dried out.

Sounds like you have covered most things, not getting through the grout lines is it?
Screw holes in fixtures been checked?
A picture of the shower area may help.

Wondering if the wall panels are now knackered if this is a mains pipe leak?

It'll be some sort of pushfit connector leaking to the main shower or head I expect.

Tell the wife to go out with your credit card and get the work done then it will be cheaper.
