I want to put down self stick tile in my bathroom. The floor is 8' X 7'. The tiles I would use are a little nicer that standard vinyl tiles, they are the kind you can grout if you would like. My worry is the floor is a chipboard, and it says not to install on that. Any advice on how to make this project work?

Thank You.

Well, you can lay down hardy-backer like you would have to do for real tile. But, i dont think the osb (chipboard) will be a problem, i have a friend who installed the same vinyl tiles in his bathroom a couple years ago and they still look good. Just be sure to vacume, wash and dry the subfloor first. Hope this helped.
