But is that the same composition as the current very smart looking black sinks? Responses from owners of current design sinks would be more relevant!

I have your setup #1 and it works well, we do drip a bit of water on the floor between sink and dishwasher, but you learn not to!! Also it gives a full clear bench on the peninsular for eating, setting out, or working or whatever. Your kitchen is slightly narrower, from memory ours is 1.6M not 1.3 as you have yours, Our peninsular has a circular end which has actually proved very beneficial for sitting round, and seats up to 5, meaning you are not sitting in a long line, but facing each other round the end, - I love it, it is a real gathering point. The outer side of the peninsular curves in to the centre, then flows out to make the circular ending, so its not protruding into the kitchen but into the other side, sorry I don't think I can add a sketch to this.

What a great idea for a small space - the plumbing shouldn't be difficult, it's all there for the washing machine

Thanks, I really like the look of a white butlers sink but just needing to know if they wear as well as a stainless steel one. Are they easy to keep clean - i scrub my present stainless steel one with slightly abrasive cleaning stuff but don't know if you'd do that to a white porcelain one??
