We have a small bathroom which we plan on completely remodeling in a few years. Until then we are just doing some minor re-decorating to get us through. Because of the current wall tiles, vanity and toilet we don't want to lift or remove them. The previous owner put in an adhesive wood floor which as you can gather is molding in the moist areas. He also only put the wood up to the toilet/vanity/tub and caulked it. We were thinking of just putting in those adhesive tile and cutting it around the toilet and vanity. Can we do this right on top of the wood floor(do we need a special adhesive)? Do we need to treat the floor or seal the mold first? Is this the best(easiest) method or will the tiles just pop right up with moisture? Thank you for any suggestions as we don't know what's underneath and are trying not to get too involved with ripping out the old flooring.
