So we installed this sink just under 12 months ago and whilst it looked fabulous at first, and we were really pleased, we have since had an issue with discolouration. We are on a grey water system so none of our cleaning products are super harsh and yet we have ended up with an area in the sink that has had the surface finish come away. It's clearly a liquid that has caused the problem given the shape of it so likely something we have had in the sink but if we can't use the sink with everyday products (that are not harsh cleaning products) then I am disappointed with the quality of the surfacing. Just a word of warning to others. Maybe stick with a stainless, the gold surface seems risky.
