I have a negative reveal on my sink. It's what I wanted so I could simply sweep crumbs off the counter into the sink. This is the best pic I have of it.

Thank you! Yours looks great. How much of an overhang is that? I am also concerned it will look odd that the overhang amount is going to vary. I want a slightly negative reveal for the reason you mentioned, but didn't want one quite so large because I didn't buy a huge sink (30" though it's really more like 28 or 29 I think) to begin with and I don't want it made even smaller.

I don't think it's more than 1/4" around...probably less. It does not reduce the size of the sink much at all. You cannot tell that the overhang amount varies at all.

Hmmm...ok, thanks! It sounds like mine will vary up to 1/4" and in some spots will be as wide as 1/2" overhang. I'm sure once it's in use I won't notice as much, but in the meantime it's a little frustrating not to be getting exactly what I want (stomps foot, lol).

I was planning to do a positive reveal for my Shaw farm sink as well as I wanted to use a cutting board that would rest on the sink edges and be flush with the counter. But my soapstone fabricator convinced me to do a slightly negative reveal. His logic was sound - My shaw sink had a slight variation of the line and so with positive reveal, you can see the changes between the straight edge of the soapstone and the sink. More importantly, my sink had a slight tilt to the front. I have drainboard on all 3 sides of the counter and as water follows a line, with a positive reveal, the water would have dripped down the soapstone edge and instead of flowing into the sink, much of it would have flowed to the front of the sink and dripped down the front. He showed me how it would drip with a temporay install and I was convinced. I am happy with my slightly negative reveal.
