Hi mate, can't help, but have seen the same problem with cheap tiles, I helped a friend by tiling his bathroom a couple of years ago. He had bought some cheap tiles from Focus, I thought the same as you that it was water getting behind the tile somehow, but have not been able to check it out as he lives a good distance away. The problem he has extends beyond the normal wet areas, but as he lets the walls get and stay very wet from condensation by not using the extractor fan, I still assumed water. Last time I was there for a quick visit. it looked like a chess board. Like you describe, the problem developed over time, there was no sign of it when it was first tiled. Be interested to see if others have seen the problem.

It'd be impossible to tell if they were dry behind without taking them off anyway, as the moisture won't permeate the glaze on the face from the biscuit.

I think tomorrow I will remove one of the tiles and check if there is any moisture behind

Good move..

Also if the pipe-work is copper and it's in a brick wall and not insulated, it can cause a lot of condensation on pipes and result in the same problem recurring.

Hi Mike - this was obviously some time ago now, but did you manage to find a reason / solution for the problem ..? We have just had a shower tiled with ceramic tiles from Topps Tiles and had the same problem.

Hi, it's now October 2023 but I too, would be interested to hear if Mike got to the bottom of this problem.
Our bath and shower were tiled in 2018 with tiles from Betta Bathrooms. Just last week, four of them in a row turned a very pale blue. At first I thought that I had dyed them by using Viakal limescale remover, which is pale blue. But that's not it. Scrubbing with neat bleach doesn't touch it. And other tiles cleaned with this product are fine.
The grout and the Silicon sealant in the vicinity of these tiles is in perfect condition.

The wall was replastered prior to tiling.
