    Default What do you put under porcelain tile when it has to be waterproof?

    It's your forever house, and you're going to live at least 20 more years, with teenagers using your shower (hours at a time), the lady of the house taking long soaks in the seperate tub. Occasionally todlers will slosh gallons out of the tub onto the floor.

    What do you use on the floor?
    Can't use Kerdi, porcelain requires latex modified thinset. What do you put over the plywood floor to waterproof? Redgard? Noble TS?.

    What do you make the walls behind the tile out of? Some of you love Denshield and some say it turns to mush. Mixed reviews on cement board. You want it waterproof but Remember plumbing leaks can happen behind the walls too. What would you use in your forever house?

    They install porcelain tile all the time over Kerdi w/unmodified thinset, So I don't know why you think otherwise. If you want to ensure a good bond, backbutter the tiles.

    Porcelain tiles have been installed with non modified thinset for centuries.

    Porcelain can be set over kerdi with no issues. Laticrete hydroban and hydrobarrier are also excellent waterproofers.
