No, QuietWalk Plus cannot be used under a tile floor. It is a vapor barrier with padding meant for a floating floor, such as hardwood, cork, linoleum or bamboo. When tiling a floor, we recommend Schluter Ditra as a substrate for ceramic and stone tile. It provides moisture protection and prevents tile and grout from cracking.
