they charge a fucking fortune and all they do is screw things to walls....... the only hard bit is the cutting of the worktop, id love one of those templates they use...
I know, I don't fancy the worktops and cutting the sink. Would do it otherwise, it's just flat pack only screwed into the walls. Sickner.
worktops are a piece of piss... cardboard templates for the worktop - just be careful where u cut the holes for the taps!
