Thanks!

I think you are going to have to get a contractor in to explain the situation for your particular bathroom. I would say no given my bathroom, but I don't know what your bathroom looks like. You might be able to take the bottom layer of tiles off the wall to accommodate the new floor and underlayment and then put back on a contrasting first layer that is like molding.

Or does that mess up the wall tiles around it? We like the wall tiles and don't want to re-do them, but we don't care for the floor. Thanks.
