Villaboard has many advantages and would be my only choice in wet room.

Cieling can be whaterver you like, no special requirements in the standards.

Good luck.

Expensive and very heavy.

Good luck.

This is a 'wet room' and as such the Standards state that all sheeting must have water resistance rating (WR).

You can use any old sheeting, but if it is not WR rated it must be fully tankled/waterproofed, the end result here is that it will cost you more not less.

Common practice is to Villaboar on all walls, it has a noce smooth finish so paints well.

Bt the way, you are waterproofing the wall to floor joint all th way around the room and installing a water stop angle in the dooeway aren't you.

Good luck.

just wondering about, except the area for tile (shower and hand basin) and water proof the joint (wall and floor), do I need water proof the the rest area before paint? I guess it's unnecessary, since the paint is already water proofed.

If you use Villaboard on all walls you only need to seal the shower area / horizontal and vertical joints plus tap penetrations.

The rest of the room needs a flashing between floor and wall, so you stick your tiles direct to the board anywhere in the room, no prep needed. just put a bit of sealant over the nail heads before you tile that area.

Areas that will be painted need a bit of filler over the nail heads and sand to a smooth finish (not sealant).

Don't forget the water stop angle in the doorway or you risk water getting out of the wet area.

Good luck.
