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!

Hello, try these eraser sponges-they are amazing for keeping these colour sinks looking great. Simply use with warm water/dishwasher liquid. http://www.heritagehardware.co.nz/itemdetails/Ecogranit-Cleaning-Sponge/2113.aspx also you can download some tips for maintaining these sinks http://www.heritagehardware.co.nz/downloads.aspx Hope this helps

Found a photo that the black stainless steel would resemble, but am looking at a 500x400 single sink

Hi, I like using butlers sinks in my designs. (needs to be a traditionally styled house) I find the quality to cost ratio at the Belfast sinks from FL bone the best. Ceramic or granite sinks are usually more robust than colour coated stainless steel sinks. Mostly the colour scratches off relatively easy. I think its an advantage to have no benchtop between you and the sink, its very practical and a nice and clean look. Make sure your benchtop is high enough for your height. Normally top of benchtop 920mm. Drop me an email if you have further questions or need design ideas email info@dlab.co.nz
