Coving in shower area - Plaster or Polystyrene

[utterlydiy]

Around all the rooms and hall etc over the years I have fitted Plaster 100mm coving.

Now I want to do the Bathroom/Shower. As it can be a damp and warm environment with shower etc..

Which coving should be used, Plaster or Polystyrene.

Also once fitted, with what/how should it be sealed against damp.

Either coving would be ok, Paint it with whatever the ceiling is painted with.

If you get a lot of condensation on the ceiling, I would recommend waterbased eggshell rather than matt emulsion. If you go for plaster coving, apply acrylic primer first.
