A facelift with e.g. new fixtures or paint I can do myself, that's not what I'm talking about. I mean a full renovation: stripping the room, putting up new drywall, then seal layer, then tiles. Then applying a new seal layer (nothing you are even allowed by insurers to do yourslef). After that tilling, electrical, plumbing, fixtures.
