Plaster and wall tiling?

[checkmate]

Hi all

I am in process of stripping my whole bathroom and removing old plasterboard down to brick.

I dont want tiles all over so looking at water resistant plasterboard then skim then paint on some walls

then where the shower tray is that 2 walls to be tiled.

one of the shower tray wall is half plasterboard and some tiling.

Behind tiles whats best? add WBP plywood then tiles or is there alternative solution?

Floor i will put 18mm plywood then tiles just wall im confused as getting mixed reviews.

The website says that it will support 50kg per m2. Your tiles are 0.64 m2, so assuming that with adhesive etc they are less than 32 kg (!!!!) it should be OK. Not sure if you need to consider the weight of the board itself and I'd imagine you'd need to make it very secure indeed on the wall behind.

See what others say though, I'm no expert!
