Any professional tilers on board?
I have a couple of ceramic tiles that have discoloured, and I’m not talking about slightly but really noticably differently darker. The tiles are glazed so don’t think there’s an issue with sealing.
There are just two tiles out of the whole bathroom, at the base of the shower unit, fitted eighteen months ago, that have gone within the last week or so.:crazy:
Advice greatfully recieved, Ta very muchly.
