A bathroom is the smallest room and the most expensive one to get wrong, because everything is buried. We replace the concealed plumbing rather than tiling over it, and we pressure test before anything is closed up.
The sequence
Strip out, new hot and cold lines, new waste and trap, pressure test, waterproofing to the floor and up the wet walls, flood test, screed, tiling, then fittings and fixtures.
Included
Sanitary ware, mixer taps, shower enclosure or partition, vanity, mirror, exhaust, lighting and door.
