If its fresh plaster, then you'll need to prime the walls with PVA before you tile, to stop the moisture from soaking through the plaster when the adhesive goes on.

I would follow the adhesive manufacturers' instructions and telephone them with any further query if necessary.

I would not use PVA in a bathroom unless specifically advised by the manufacturer of either the PVA or the adhesive. The isssue is that if there is a lot of steam in the bathroom, it might weaken the PVA bond to the wall. (The tile adhesive, is stuck to the PVA so if the PVA fails, the tile will fall off).

I recently did a bathroom and did not use PVA.

Never use PVA on new plaster just contact the makers of the skimcoat they will confirm this 100%
