Ceramic tile over unknown subfloor

[Jaz]

I love shulter. I just still don't see how kerdi is waterproof. And a membrane wouldn't be pointless. There are different membranes... waterproof crack membrane. I wound use ditra mat and go over the existing tile. Skuff up the existing tile and lay the mat over it. Don't forget to use unmodified thinset

If you love it, learn the name. It's Schluter. Why can't you see that Kerdi is waterproof, and will make a great shower? Ditra over existing vinyl and unmodified. Oh Boy!

Its horrible that Schluter has a 5 year warranty.
There is better stuff out there I don't use it anymore anyway.
