The whole point of a wet room is the continuous floor from the shower area outwards. Assuming you can overcome the problems of drainage and access to the trap, movement of the substrates and leakage, the visual impact is lost in a small room so why go to the effort and expense? A shower tray with upstands installed with shower boards will give a lifetime of good service and no leaks if you use quality sealants with good mould inhibitors and take care to maintain it, drying it out and keeping the room well ventilated and clean the shower regularly to prevent build up of lime scale.
