Oh Boobyjood, so glad you saw this post - I've been trying to find someone who has the same sink to give a warts n all account for it!
I've been told that black sinks show water stains in hard-water areas (which we are in), but I'm sure with the right products and frequent cleaning, it will be fine.
We're having a granite worktop too - not black though, but lots of black in it, so it will go well with the sink.
Anything I should know about it? I know it's 'just' a sink - but it's not the norm, and don't want to spend the money on it and the worktop and soon after have regrets!
