Mine starts next week. It has come in at £18000, which is a lot more than I expected when we started getting quotes (more than we paid for our first house
), but that is for knocking down the stud wall to the separate loo, replacing and moving said loo (so moving the soil pipe), a new bath, shower, basin and units, as well as lowering the ceiling and replacing it with a UPVC one, and all the tiling, lighting, flooring and accessories. It also includes skip hire and waste disposal. The people we went with are in the middle of the quotes price wise, but there wasn't much in it. I think they are just expensive now.
