I dont know where you lot get your prices from..........

To supply and fit a half decent SS sink and mixer tap i would charge about £260

Sink- for a decentish one about £60
Taps-For a mixer tap that wont fall apart in 5 minutes about £100

Labour for it would be half a day-£100

You get what you pay for and i would NOT be buying a cheap shitty sink and taps
