Oh yeah, I've actually been in the middle of that with a customer warranty issue on that one. (One that the customer had to pay to have the crack repaired rather than the manufacturer.) You want to choose at least a small radius rather than a sharp 90 degree corner. Sharp inside corners stress much worse when your cabinets or floors (inevitably) settle. Sharp outside corners are there merely to slice your skin open if you get too close. You can still get a modern look with a 1/2" radius.

Yes. I wanted square for the modern look I love, but I have rounded corners for the possible absence of chipping or damage. I am sorry, today, that I didn't get square corners. But perhaps if I were to get damage, oh, I don't know, but yes, I have heard of such a thing and did such a thing-even tho I wanted modern. another slight regret, very, very, very slight. i am happy.

Thank you, live_wire_oak! I wasn't sure what radius he recommended, but it's good to have a number now. I'll go find some pics of a 1/2 in. radius.

Just to put it in an easy to picture perspective - a quarter is just under an inch in diameter. So your 1/2" radius corner would be approximately the size of 1/4 of that quarter. Pretty close to square when applied to a countertop.

I just went to the granite showroom today to discuss this very thing. The salesman told me the inside corners should always be slightly rounded, not sharp. And for the outside corners, they can be sharper but he said the same thing live wire did about catching yourself on the corners. I'm going to look for pics now of 1/2" radius.

I just did a 1/2" radius and it looks fairly square. I will try to remember to take a picture tomorrow.

Here is a graphic of different edges. I'm going with eased edges to go with the more contemporary look. (Although considering beveled also.) As someone said in another thread, the full bullnose looks somewhat dated now, although frankly I still like it. It looks more finished to me for some reason than the eased edge. Notice that with the eased the corners aren't 90 degrees.

That's a good graphic! C looks acceptable to me, and that's a 1 inch radius.

What about inside corners like below? Does it come standard a certain way? Or is that aesthetic & personal choice as well. I'm assuming if you had eased or rounded edges on your countertops, it would make sense to have rounded corners as well? Thoughts?

Sean:

If your fabricator uses a CNC machine to profile and polish edges, you're getting a 2 1/2" or so inside radius, like it or not, because that's the smallest size of his tooling. It's stronger and less likely to fail.

The only way to get a 90* corner with a CNC machined edge is to make a French miter in the corners.

I know this thread is old, but here goes.
Having a granite L-Shaped wall bar top being contracted in Steel Gray granite. No outside corners to worry about.
Template guy was the owner and never even brought up any of these questions, not to mention where the seam would be? When I did ask about the seam, after he was gone, told that it needs to be 90’ just left of the corner, where the 2 cabinet bases come together.
Just thinking a 1” radius on that inside corner wouldn’t be bad.
Brand new basement finish.
Excited but a little concerned about the granite.
