I have a very small kitchen as you can see! I'd like to replace the worktop and have a black granite half bowl sink. I can't afford to change the units but I don't mind them but not sure what colour worktop. I'm replacing the flooring throughout the open plan kitchen and living room area with walnut laminate. I will be keeping the dark grey walls. Would really appreciate some ideas please on colour and what sort of material for the worktop. Thanks all.
