Hmm, ok thanks. Just building a list of everything he’s done wrong at the moment. Have a couple of new tilers in for quotes and they’ve both said the same as everyone here. Start again.Plasterboard is fine in the shower as long as it’s tanked.
Thin ply overlay is not much good, I always tile my floors on 6mm Hardie screwed and glued.
Not that it really matters now, it’s got to all come out anyway.
What would have been involved in tanking it because I don’t remember seeing anything other than the plasterboard?
