I have a vinyl floor, not tiles one full piece, over concrete, in my bathroom. The vinyl is solid and perfectly fitting to all the walls and runs beneath the bath, shower, toilet, sink and fitted wall cupboards. It is screwed to. The vinyl floor was there in an empty room before the bathroom was created. The only way it could be completely removed would be to remove the complete bathroom, this is not an option :-).
I am looking to tile over the vinyl with cork tiles. The questions is: will normal cork tile adhesive stick ok to the vinyl or should I treat the vinyl in some way?
