Musty smelling wall on other side of shower stall

Donna, here is what I suggest.
1. You need to attempt to find the source of the moisture. I would suggest purchasing or finding a company that has a boroscope. You could then inspect the interior of the wall to see if you have anything growing (mold or mildew). If you don’t want to go through the hassle of finding one of these, find someone that can remove some of the wall in the closet (could be a plumber) so that it can be inspected.
2. Stop the leak. (Repair pipes or showerstall, etc)
3. Remove and replace any insulation that has turned black.
4. If the smell still persists it would be helpful to treat any areas that had mildew or mold growing on them. One way to do this is with a heat treatment. This is the same method of heat treatment that is used to control termites in the southwestern portion of the United States.

Do you have any ventilation for this space?

Thanks very much for your advice.

I have discovered a productcalled megasealed. If you want more info they have a website, the address is megasealed.com.au

It sounds like an easy non-messy and quick way to solve my problem.

Thanks again.

Regards
Donna

Donna,
Megaseal removes the grout and replaces it with their product to seal the tiles.
If the pipework inside the wall is leaking they will not stop your problem.
You need to have the shower combination, waste, and tapware checked before spending lots of money sealing the tiles. If the combination is the problem then it needs replacing, which will mean removing tiles, wasting the Megaseal.
Get a plumber in if you feel you cannot test these parts youself.

I had the job done today. They checked all the plumbing first and then used some type of tool on the wall(on the other side of the wall) which checks rising damp, to check where the water went up to. It had green and red lights on it.

I also get a 12 year guarantee on the work so I am more than happy with that.

Thanks for the info.
