Whoever did mine before I moved in did a piss poor job and a half. Laid down wooden flooring, got so soaked, was like walking on wet pillows, till it collapsed! A council contractor just started yesterday on mine removing the soaking wet wood pulp down to the concrete base. He's waiting on some screed & materials to arrive, hopefully tomorrow! When I plastered outside walls, I used plasterciser, thick latex liquid mixed in with the cement. Is plasterciser not used in wet rooms to help waterproof? Contractor told me screed would be dry in 2 hours. 2 hours?! really?! The surveyor said once concreted and dried, latex would be poured over to waterproof, though from the last time my kitchen floor was done, it took overnight to dry. Then, new blue vinyl will go on top of that, sealed around the edges. Drain is already in place with a 12 vdc pump. I was expecting a new drainage pump system. Think I would have preferred ceramic tiles to vinyl. Waited nearly a year now to get it completed! That's the caancill for ya!

and how to find this nice set, please?

This looks insanely over engineered
