Hallo
I've had a quote to redo the bathroom and one thing that jumped out at me was the cost of tiling - £1700 to install a waterproof membrane (don't think I've ever had one before) and to tile.
This doesn't include getting rid of old tiles or plastering.
It's for both the floor and the walls but it is a small bathroom. It's a lot even for London isn't it? Or is that the going rate at the moment?
