We chose the zero radius style you are looking at. It is not at all a pain to clean the corners; more stuff fits in the sink and it looks totally cool. We love ours and would be disappointed with anything less.

IMO no, not a pain to clean, at least ours isn't.

Before I finally made my decision, I never realized how difficult picking a sink could be. If you want to avoid any possible problems with zero radius, here's a tight radius 32" Ticor sink. Looks like it might have a ridge for accessories judging by everything that comes with it. I wanted a tight radius 9" depth but could only find it by Franke and it was very expensive. So I bought a 30" zero radius 9" depth Ticor from Galaxy based upon all the raves about Ticor on GW and so far I am very happy with it.

lbrody, Sorry for some wrong information! That Ticor link is a zero radius. Still really nice. They have a 31 1/4 that is tight radius.

I have a similar-style sink made by KWC. My biggest complain is not about corners, but the flat bottom. The bottom is too flat for the water to bring stuffs to the drainage and I have to use my hands to do just that. Do you guys have the same problem or does it bother you at all?

That Ticor tight-radius sink that Gwentm posted is nice. If I were choosing between that one and the Kraus, I'd choose the Kraus only because I prefer that the Kraus drain is "offset", i.e. toward the back rather than directly in the center. With the drain a bit toward the back, you can set pans down in the sink without covering the drain, and also have more room under your sink for storage (the drain and disposal will not be so much in the way).

You can sometimes find deals on C-Tech sinks on ebay for around $285 or less. This is the one I bought, it has the back drain and is 16 gauge. They often have others to pick from and they are nice quality, some are 16 gauge with a 15 gauge rim. The lower the gauge the better for long looking good life.

Thank you, everyone, for your input!
I do like the Ticor example but had already thought that I'd prefer the drain set towards the back. I do really like the look of the Kraus tight radius sink.

The Copenhagen one is lovely, but very industrial-looking which actually probably isn't right w/ my kitchen.

Are there other brands I should look at? Or any other voices of experience?
