You have been given good advice already.
Yep aquapanel
I agree with the others, a cement product like Aquapanel. Use Aquapanel Tape on joints immediately before tiling.
British Gypsum say you could tile over moisture resistant (green) plasterboard for a shower. I think without a skim coat, it will take tiles up to 38 kg/m². A skim coat reduces this to 22 kg/m². I've used this around a bath with a shower mixer but I wouldn't use it in a shower enclosure.
I think ordinary plasterboard can only be used for basin splash backs (not showers) and even then requires two coats plasterboard sealer and NOT PVA, which is water soluble. (I thought I'd ruined a brush with dried out PVA. However, I soaked it for a few days and it cleaned up a treat.)

A fibre cement board is all the rage at the moment, with everyone praising it to the sky, but the fact remains that plain old plasterboard will do just fine
The whole point is to do the tiling properly and grout/silicone properly so that the water stays in the shower.
Dodgy tilers may insist on Aquapanel and the like

You know fine well Woodstock, that time and movement (particularly with baths) coupled with the fact that not all tiling is completely waterproof, that rotting plasterboard is the downfall of many a shower enclosure.
Surely waterproof grout is waterproof!
If I was doing an enclosure for some students or similar, then yes some extra "insurance" would be a good thing.
But for some DIY work where the OP is presumably competant, would do the work properly, would look after it and would see if things are wearing in the future and need a bit of remedial work, then the need for a special back panel is lessened.

Exactly.
Water resistant not waterproof.
Tiles and grout let water through but dry out and do not degrade. This will over time damage plaster board. If you are using plaster board use a tanking kit. If using aquapanel do not skim. (plaster does not stick)
I ended up using a combination of the two. Aquapanel for new partition, tanking for existing wall. I have had no problems so far. I got all this advice on this website on the Tiling Forum. (Thanks guys)
Dont save pennies now to redo soon.
Good luck.
NO PVA IN WET AREAS........

If it was truly waterproof then you could use it in swimming pools but the label usually says you can't.
If you follow manufacturer's instructions then I think British Gypsum say you must use MR board in showers.This was my thought Woody - if tiles and grout are waterproof in the first place, the backing could be tissue paper!!!... well, u know what I mean!
Except for expensive epoxy products, waterproof adhesive & grout is only waterproof in the sense it won’t disintegrate when wet, it will still absorb moisture.
Not in wet areas it won’t
See above regarding the definition of waterproof addy/grout.
As I always recommend it for wet areas, I could take exception to that but I won’t.
PB in a bath/shower room should always be MR but in wet areas use a waterproof tile backer board (12.5mm); if you use PB in wet areas, you should always tank it, even MR will disintegrate eventually despite what BG say; you would not believe the state of some of the PB I rip out.
Deansplit use the Aquapanel; as FMT & PBD say, you’ve been given good advice already; but if you want further proof rather than take my word for it look back through the Tiling archive posts to see what the other pro tillers say; there are at least 3 current regular contributors & if you go back over a year there are contrubutions from 2 others who are no longer with us; or so they would have you belive
Woody; weve never had any probs & I respect you as one of the regular contributors on this forum who’s posts are normally informative & sensible. Your not a troll as far as I’ve seen & I’ve no wish to fall out with you but in this case you’ve got it wrong M8; don’t dig yourself a big hole & fall into it, do some research of your own.
This forum gives excellent advice from genuine trade contributors & posting misleading information is not good for the folks that come looking for it!
I've used Aquapanel (cheap enough on the net) as my previous house had standard wall board and it rotted. Cracks in grout are not water proof as I found out to my peril but it did take about 8 years to totally fail. Once the board was wet it flexed and swelled and caused the grout to crack even more accelerating the problem.
Why wouldn't you use Aquapanel?
