Tiling straight onto plaster in shower area?
Having shower tiled, is it okay to tile straight onto old plaster in a shower space?
One wall has some sort of backing board on it but the others don't. Plaster isn't in particularly good condition either, especially around the bottom of the walls (see pics). Having floor and walls tiled (like a wet room).
Tiler is starting in a few days and this is how it has been done ready for him.
(Unsure whether the tiler will be doing anything else beforehand but I get the impression not, won't be able to find out until he starts).
