It's not aqua board

[Beginningoftheend]

So I have a room that will be my bathroom. Half stud wall. Half external wall. I have plasterboarded my stud walls with normal 12.5mm plasterboard and then skimmed the lot with the intention of having shower and tiles on external section. Unfortunately we have to have the shower and tiles on stud. Wall due to structural problems. Can I leave the normal. Plasterboard and skim on and tile and, fix shower or am. I going to have to re plaster board the stud wal with aqua board.

If you want tiles then you have 2 choices;
1) remove the plasterboard you have already installed and replace or over sheet with water resistant plasterboard, then skim and tile.
2) Skim and allow to dry then 'Tank' the walls before tiling.

But following an incident at a girlfriends some years ago I'll never have tiles around a shower - we think the grouting had cracked so the plasterboard had become wet and lost structural strength, the wall was 'tapped' as she turned the taps off - the whole wall of tiles collapsed into the bath; if she hadn't been so quick her legs would have been shredded.

Today I always use shower panels, what they cost is saved in time taken to install.

Thanks that sounds a horrible experience. Does it not matter that is already skimmed and what is tanked?

Why plaster the plasterboard prior to tanking? IIRC plasterboard without plaster has a higher weight bearing rating than plastered plaster board.

With regard to your girlfriend, glad to hear that she wasn't injured but it sounds as if the tiler effed up. I still know builders that, for example, still insist on using PVA to seal new plaster rather than SBR prior to tiling.

Don't skim it... for starters a 4 week wait to tile (for good reason) and it reduces the load bearing capacity from 32kg to 20kg on plasterboard.
