hi spooney

your thickness of plasterboard will depend on whether you have to match up against the plasterboard that is already there. if you're reboarding a room from scratch, then it's your choice whether you want 9 or 12mm. You might have to take into account existing door frames etc.

plain plasterboard should be primed. if you are using plasterboard in a showering area, get a tanking kit too. tank the plasterboard and then prime the tanking.

I'm sure you can get water resistent backer boards in many different thicknesses. I have only used 6mm thick sheets myself, but it's worth speaking to the manufacturers and seeing what they offer.

Spooney, use 12.5mm plasterboard and hardibacker board. Priming plasterboard is a personal choice, some people do and some don't, but if there's exposed edges on your plasterboard they do need priming. Your backer boards don't need priming but the joints will need taping with tanking tape.

Bear in mind that if the existing board you are matching to are skimmed you will still have a difference in the thickness

Spooney is not the OP so I'm assuming he's not matching up to anything and working from a blank canvas:thumbsup:
