I purchased a new kitchen to fit myself including stainless steel sink and taps only to find that after a few months the sink was badly stained. I contacted B&Q who asked for pictures to send to their quality control team and after a couple of weeks the reply was that they wouldn't do anything as nobody else had reported this problem before me and that various cleaning chemicals had been used. Really - we'd been cleaning the sink! The ultra thin, poor quality material used to make this sink is disappointing and the "15 year warranty" advertised is obviously some kind of a joke. Do yourself a favour and avoid B&Q. Go to a proper kitchen supplier.
