Tiling

Wet room floor tiles moving underfoot

Hello - we are having an en-suite shower room re-fitted into a wet room, contracted with a local plumbing/bathroom fitting company who are providing the tiler. We are not happy with the overall quality of the work, but I am particularly worried about the fact that I can feel the porcelain floor tiles moving slightly underfoot when I walk on them. I am concerned that if the tiles can move relative to each other, the grouting won't last and we will end up with leaks. Can anyone confirm (or otherwise) that I shouldn't be able to feel wet room floor tiles moving underfoot? The en-suite previously had a shower tray and Respertex wall panels at one end, and the rest of the floor had vinyl tiles (which didn't move noticeably). I saw that a plywood-type panel with a drain was fitted under the shower area after the shower tray was removed, but didn't see how the tanking was done. We also have a suspicion that at the other end the new porcelain floor tiles have been installed on top of the old vinyl tiles, as we didn't see them removed and couldn't find the old ones in the pile of rubbish left outside the house. Would it be acceptable to put new porcelain floor tiles on top of old vinyl tiles? We are in dispute with the bathroom fitter over repeated failures to turn up when promised, and the general quality of the work, but my biggest worry is leaks causing damage to the ceiling below. Any advice gratefully received!
