I also use the sprayer to "push" stuff towards the drain, but I think I did with my groady old pre-reno kitchen sink, too. I honestly don't find the corners a big deal to keep clean--I jab the sponge into the corners when I'm cleaning the sink. If I'm spraying the sink down with SS spray, I might pay a little extra attention to the corners when I'm wiping it out with the microfiber cloth, but nothing major. Once in a blue moon (every few months?), I'll take a cotton swab, and jab that into the corners to clean out any SS spray residue, and to see if there's any of that gunk build-up that I've read about. Ususally the only thing on the swab will be a little bit of the spray and occasionally a little greyish-metal color like I'll sometimes get on my microfiber cloths or dishtowels when I use them to clean SS. I have never found my 0-radius sink to be difficult to clean at all (a Julien sink BTW, 10" deep and we use a sink grid).

Call the Caesarstone 800#. They are very helpful. They gave us detailed info about cutting Caesarstone into floor tiles. They cut the tile for you in any size. So they can probably do a sink. Give them a call. They'll be able to answer all your questions.

Morning, I'll be honest, I didn't really ask about the inside of the sink radius. Everywhere else is 1/8", corners etc and the reveal is flush. Our island is 9 x 4 as we were told that each slab can do 120" without a seam. We do have a seam along the cabinet wall, but its barely noticeable at all!!! We're blizzard ceasarstone as well. Love it. So far so good with the stain removal!!

We have 2 single bowl stainless steel sinks on the opposite sides of our kitchen. I really loved them at first but after a couple of years I started becoming less satisfied and the dissatisfaction grew over time. Now, 7 years after putting them in, I regret our choice. It's one of the few regrets I have with the kitchen and unfortunately, it's nearly impossible to change. We constantly have to brush out the corners, even when the rest of the sink looks fine. When buying sink brushes I have to make sure they will actually reach into the corners because a lot of the times the plastic head will prevent the bristles from getting there. Water drains slowly because of the flatness of the sink and a lot of food chunks and sludge get left behind. This is particularly a problem with the larger sink where we have a grid. It's hard to nudge the bits of food toward the drain when the grid is in the way and the spray on our faucet isn't strong enough for particularly sticky food. And often a slight sludge will build up in the indents running toward the drain. I've had stainless steel sinks in the past but I never had problems like the ones I have with the zero radius sinks. Bottom line, I would not get another zero radius sink. I would look at the sinks that are close to zero radius but have more forgiving corners. I love the flat surface our sink grid gives us. There is no need for a flat sink under the grid and I'd prefer a sink with more of a slope so that it would drain more quickly and thoroughly. I've been really happy with the dimensions of our 2 sinks. Our large sink is 30"x17"x10" and it's where I do most of the work. It's large enough to handle several tasks at once. Our other sink is 13"x18"x10". It got hooked up about a month before the larger sink and I found I could perform just about any task in it (the depth allowed me space to rinse dishes under the faucet even when there was soapy water on the bottom.) Again, I really loved the sinks at first. But, as with many things that age, they require more and more maintenance to keep them looking good. I didn't have to pay the same attention to the corners during the first several year as I do now. Maybe wear and tear and minute scratches give more places for gunk to cling.
