There is no “better.” There’s fashion and current style though. I have a radius of greater that that, much to the chagrin of my design assistant. Kitchens should be functional and if your up to the little extra time involved in cleaning those corners, and it’s the look you want, go for it.

I ordered the one from kraus. it's has the 10 degree radius. Love how the zero radius look; however the 10 radius looks square enough for me and not more easier on the clenajnf per the reviews. it looks the same to me online.

It was special ordered from homedepot and lowes, it would have take abkut 2 weeks to get. I went ahead and ordered it from Amazon. I should have it in 2 days.

Luckyblueeye below is the sink that I installed. So far I like It.

I have absolutely no idea what "10 degree" is supposed to mean in this context. Must be some funky marketing term.

Having said that, the reason why people prefer minimal radius (other than aesthetics) is that it makes it easier to use the entire space. If you have a pronounced radius and you try to place large cookie sheets into the bottom of the sink, they might not fit. With zero radius, that problem goes away.

But even if you have a quarter inch or half inch radius, your cookie sheets are going to fit. They rarely have perfectly sharp corners either.

And from a functional point of view, even a tiny bit of a radius does make it much easier to clean the corners of the sink than having a perfectly rectangular corner. Does it make a big difference? Nope, not really. But I do understand why manufacturers opt for maintaining just the slightest bit of a radius.

As as for looks, either one looks just fine to me. I don't think I would base my purchasing decision solely on whether the corners are zero radius vs. minimal radius. There are more important design decisions.

Sweetshome, how do you feel about the 4 lines running along the bottom of the sink? I actually prefer a sink that's NOT zero radius, but I can't find one that's as large as I want without the squared corners, and they all have the lines in the bottom.

I have a zero radius. It is very cool looking, but nearly impossible to clean the corners.

Big sinks are difficult to drain reliably. This is a frequent complaint that you hear about fireclay and about some cast iron sinks. Leaving puddles of water in the bottom of the sink isn't exactly user friendly. Stainless steel and copper sinks solve this problem by having a well-defined slope towards the drain. And that's what gives you the four lines. Think of it as a feature.

If you have unusual requirements for your sink, you can always have it custom-made. A particularly highly-recommended manufacturer is www.rachiele.com. You'll occasionally see the owner (Dino Rachiele) post here, too. He is extremely knowledgeable about everything sink related. His sinks are well-thought-out. But for a fee, he'll build you anything you ask for (assuming it can actually be built, of course).

Sinks that don't evacuate properly are probably installed in tops that are out of level. Gravity doesn't care how large a sink is.

The lines in the sink are fine. I have not come across any problems so far. I am happy with the sink.
