Thanks Admin and Mudster for your replies. I made a mistake in my original post: I'm quite happy going for the solid bed of flexible adhesive, it was only the Ditra matting I was shying away from on a cost basis.

Admin, you say 'I'd at least use a pourable flexible thick-bed adhesive', which would be fine with me. Do you think there would be much advantage in using the Ditra matting as well? Asking around, it seems that Ditra is not used all that often- under what circumstances is it deemed entirely necessary?

Mudster, you say you'd never fit stone to a floating floor- does this mean you wouldn't fit any kind of tiles to such a floor? If not, can you tell me why/what would happen if I did? The reason we went for a floating floor instead of a screed was to preserve headroom- this floor is in a lean-to, so the ceiling at one end is 4m high, but on the other side it's only just high enough for a doorway. It 'seems' pretty solid, but I know that might not mean much. How would you recommend I finish this floor? It's the kitchen, so we really want stone/tiles rather than wood or carpet.

Thank you for the advice so far, look forward to some more useful pearls of wisdom!
