Tiling On Plasterboard In A Bathroom

[Dylan M]

Hey guys. This is my first time so if I'm in the wrong forum section. Sorry in advance.

Well this is my problem. My mum has gotten a person to do teh tiling and stuff in our bathroom. He recently put plasterboard onto the wall side where the bath will be put. He started to tile on it with the adhesive so far. I was just wondering is this the correct way to do it? 'Cause I was researching it and people are saying that if the tiles are going straight onto adhesive then onto the plasterboard, the plasterboard may rot if water get's in? I'm worried that we should have skimmed this before?

If there is any help or ideas, or if you want me to make it any simpler and explain it in further detail I will try to to this for you.

Thank's in advance.

Tell your tiler to join here. It sounds to me that he may learn a few things. I mean that in a nice way.
