tiling onto plasterboard...possible?
Discussion
It's fine - but seal the plasterboard with PVA or a decent primer first.

Be sure to use waterproof PVA in a bathroom though...Or, have a read of this: http://www.british-gypsum.com/PDF/wb_tiling_04_06....

Most tilers round here use WBP ply in bathrooms, or Knauf Aquapanel. The main problem with plasterboard in bathrooms is water penetration through gaps in the grout/sealant.
This causes the plaster in the board to fail, and the tiles to end up on the floor. Moisture Resistant board has resistance in the paper covering the board, but this is, of course open at the ends.

It's already been put up by the people appointed by my insurance co (despite me specifically instructing them to ONLY plaster and leave everything else to me as I'm sick to the back teeth of their incompetence). I was thinking much the same as you say wrt to plasterboard however it's in a toilet/basin room so there's hopefully not going to be a great deal of moisture, ie. no shower/bath condensation. This causes the plaster in the board to fail, and the tiles to end up on the floor. Moisture Resistant board has resistance in the paper covering the board, but this is, of course open at the ends.
Essentially, aside from the area around the basin (which is plyboard) the areas of plasterboard shouldn't be getting wet at all unless I start chucking water all over the place.

Note water proof grout means the grout will not deteriorate on contact with water. It will let that water through to the plasterboard which will eventually rot through the water contact.
You could use a tanking solution such as that from Bal which creates a barrier to stop water from rotting the plasterboard.

Some may say it is OTT, but I think you might as well do the job properly and at least you know you want have to rip it all out in future due to water damage to the plasterboard.

Do Not use PVA, Never ever use PVA.
You wan't something like BAL Prime APD or the like.
Agree, PVA will "reactivate" if water/moister seeps through any cracks/gaps in the grout.You wan't something like BAL Prime APD or the like.
For years I was getting problems with tiles falling off plasterboard in a basement flat shower room. It was pointed out to me that the PVA was "reactivating" through the water/moister, therefore loosing it's adhesiveness and sealing affectiveness. It was suggested to me to use in place of plasterboard aquapanels, and BAL Prime APD and an appropriate water resistant tile adhesive/grout. That was 3 years ago, and the shower room still looks as good as new.

You could always use Aquapanel or Hardibacker.
Sorry, I meant the shower room exists and is already tiled, was meaning more if I wanted to retile it.The toilet/basin room has been plasterboarded already and I'm reluctant to strip it out again. In entirety I'm talking <2m square of plasterboard, about 3ft away from any water source (the basin) so it's really not going to get wet at all.
ETA I didn't look too closely at the stuff they'd put in actually, so it may along the lines you mention. Cheers

Sorry for the bump.
Does this stuff work the other way? ie a barrier to damp from the outside?
Ground floor window, underneath of which is old stonework directly facing onto soil/ground. Am fairly sure damp is coming in through this brickwork and want to seal it up. If not the above, what else can I use?
TIA

Or as I found recently your arse going through the plasterboard should you slip due to it being completely waterlogged and not much stronger than a wet paper bag.
