Saw someone else mention some kind of membrane. Not familiar with that although I have seen Mike Holmes use an orange material that gets thinset to the floor then the tile laid on that.

Schluter ditra. Was going to use that but the tile needs to be at least 2x2 which this one isn’t. Might have to change the tile I use

Even if your tile comes on the mesh backing? Doesn’t look like individual tiles.

Both ditra and kerdi board require at least a 2x2 tile to get the warranty from schluter. Both substrates aren’t stiff enough to resist the point load that could result from weight on small tiles.

When you get bigger tiles, the tiles themselves, and the thicker thinset bed, make for a stiffer assembly.
