Bathroom Fitting

Fitter used plasterboard behind shower tiles. What can I do if it goes wrong?

I recently had my bathroom redecorated, the main thing being the retiling of the walls behind the sink, toilet and shower. When the old tiles were removed there was plasterboard behind which came away with the tiles, plus the false wall behind one wall of the shower (to make the room a right-angle) turned out to be a sheet of plywood which was damp on the bottom half. The builder replaced all this with new plasterboard and tiled over it. I've since learnt that this is a really bad idea, and that waterproof cement board should have been used rather than normal plasterboard. I didn't say anything at the time of fitting as I didn't know anything about what materials should and shouldn't be used and have paid the builder/decorater for completing his work. Having read about the possible consequences online, I'm really worried now that in the future this will deteriorate and fall apart. Should I mention my concerns to the builder who did it now, or just wait and see if something does go wrong before worrying about it? I'm not sure what rights I would have if something does go wrong. Any advice would be appreciated.
