Install 3 bidet toilet seats (I already have all 3 seats). 2 of the 3 seats need the concealed-cistern work: the water connection needs to be taken from the pipe going to the cistern, the cistern is concealed behind a tiled wall so the tile will need to be cut through to access it, and the brass pipe will need to be cut to take the connection (tee-off). The 3rd seat is a straightforward install — that toilet has an exposed cistern (not concealed) with the pipe clearly visible, so cutting will probably not be needed for that one. Plumber to supply fittings, valves and hoses as needed. Location: Ruislip, London.
