I have a small downstairs cloakroom that needs finishing off. The toilet is plumbed in, the floor is finished and waste pipes and water supply are in place. I need someone to fit the sink(supplied), to plaster an area 80x50cm approx, box in pipes and tile walls up to height of about 1 meter. The room is about 104x80cm. Had a quote of £450 to do the work and haggled him down to £400. Is this about right? Still sounds a bit much. Any comments much appreciated
