Good idea, thanks.

I was just reading up on Ditra after reading a thread here on EasyMat
where others mentioned it. Does it help avoid this kind of cracking?

Probably so, but you could test it by drilling a tiny whole through the
shower pan to see what you hit. It could easily be patched if you choose
to continue using the shower pan as is, whether it's supported by concrete
or not.

Well--if I pound it with my heel and I hear a resonant thud, does that
mean it's sitting on a bed of concrete?

If the plastic shower pan has been set on a bed of concrete (as many
plastic shower pans and tubs are), then it would probably have the
stability to hold up under the tile. This method for installing plastic
poducts was code in place I lived.

A plastic shower pan could never hold the weight without flexing and
cracking the tile.

Just brainstorming here, expecting No for an answer. If I have a
prefabricated shower floor and I want a tile floor, can I instead just
tile the prefab floor instead of taking it out and starting all over
with pre-pan and paper and all that?
