With that sort of treatment, forget floating floors. You'll be ripping it up again in not time, particularly the thin veneer stuff. You could put solid timber down but it will be more expensive. At least you can sand it and polish it again when required but with that sort of treatment it will look pretty crappy in no time so i don't see the point in doing it.
Sounds to me like tiles are the go. Maybe terra-cotta, not ceramic.
If at first you don't succeed, give something else a go. Life is far too short to waste time trying.
