I've visited this thread several times and it's interesting that it is still fairly active. I'm looking at the Cristadur waterfall 150 in Bronze. Wayfair carried them a few months ago with good prices but when I checked last night, there were no Schock or Houzer sinks listed on their site. I have found a supplier from Germany on eBay, his listings are rather obscure and you have to dig deep to find them. He carries the entire line including vintage models and colors; GREAT prices with a flat $145 shipping. I currently have a Swanstone in black that drove me crazy when it was new with water marks and looking dry, until I wiped it down with coconut oil a couple of years ago and I've not touched it again. It now wipes down and is cleaned continually from just washing dishes and looks brand new. I'm looking at Schock over Blanco for my remodel in a different house due to the unique look of the waterfall, but I'm worried that it might suffer from being less than utilitarian. They have a matching 15" prep sink which I plan to install as well. Anyone have any real experience with the waterfall design or Schock for that matter?

Tuffle or biscuit would work IMO. My preference is not to go with a dark brown sink. I love dark brown wood and have it in my kitchen but to me on a sink it just doesn't look right. Our quartz is lighter that your granite slab but I think I'd still choose biscuit because I prefer a lighter color sink (helps make the room feel lighter and brighter but that's my personal preference). We've had no problems with staining but also don't have kids in the house and clean up after every meal.

If you do a search at the bottom of the page under blanco silgranit sinks you should see a lot of posts pop up. There's been several posts on this subject. I have the Blanco super single precis in the black. My faucet is the Kohler Forte in stainless. My appliances are stainless also. Most love their silgranit sinks. HTH.

What is "Darlington"? Is it a tile? A countertop material? And if by "Truffle" and "Metallic Gray" you are talking about Blanco Silgranit sink colors, I suggest you call Blanco's customer service number (don't email, call), and have them send you color chips of those colors so you can see them at home which will help you decide.
