Is this a new location for the shower? It was dumb to run water in a
location like that to start with.

If the first plumber refuses to come back he should be reported to
whatever agency oversees the licenses in your country as that is
irresponsible. He may be liable for any costs you incur if it was his
fault.

It must be fixed, even if times have to be removed. I can't see it so
cannot suggest a better method.
The "plumber" was likely just a handyman "bodger", not a registered
tradesman. Most likely cause of the dampness is not sealing around
the pipes where they penetrate the tile/backer. I'd pull the
estachions and caulk behind them with a good tile and tub caulk first
before doing any extensive/expensive deconstruction and see if that
solves the problem. Also seal all the tile grout with a clear tile
sealer made for the job.


Before I caulked them I would inspect carefully what you can see with
the covers removed. My Depstech endoscope would perhaps be very helpful
in diagnosing the problem. If you operate it the way you see the leak,
you might be able to see better where the leak is through any gaps
around the through the tile fittings.

If the leak only happens when filling the tub, and not the shower, that
would suggest a leak in the pipes from the valve to the shower. And
vise-versa.

After reading it is only when "filling the tub" - and NOT using the
shower:
90+% chance it is the diveerter or the tub filling spout - the
diverter would be my first guess - with water running back into the
wall. It can NOT be the pipes if it doesn't leak whenthe water is not
running - and particularly if not when the dhower is running (not
filling the tub)

Or mabee it is only when there IS water in the tub - which could be a
drain issue or a cracked (acrylic) tub - - -

Had one that only leaked with the tub full that was a problem with the
seal around the drain - and another that was a cracked tub., Resealing
the drain "tailpiece" solved the one - the other needed a tub
replacement but was patched with epoxy in the short term (don't know
if it was ever replaced) The drain was my daughter's.
