I know what we just did in my kitchen with the Shaws sink... I have a slight, about 1/8+ of inch, negative reveal and 1.25 inch overhang on the counters. Not sure if that is standard or not but I think it looks good.

One thing I would recommend is that you are specific about where you want your faucet if it matters to you. I wanted to be sure the water went straight into the drain, just my personal preference.

Another thing I would ask is if you are going to have any seams and where they are. If your not happy about where they are, now is the time to let the fabricator know in case there are other options.

I know I will have seams in the island- not my preference- but what has to happen with this type of ss. The faucet location is HUGE, as I specifically bought the faucet with enough reach to hit the center of the drain. Do they do the faucet holes on site or do they do that in the fabrication shop?

For my soapstone, they did the templating and then, when they installed the countertop, they did the holes for the faucet, soap dispenser, etc.
