What sort of sink is it? From the kohler undermounts I've seen, they're very unfinished along the top; I opted for a slight negative reveal which appears to be the standard (vs nice stainless steel sinks in kitchen)

We just had 2 bathroom sinks like Mr_Garden's installed, one each in our 2 bathrooms. They have a slightly negative reveal. The same granite guys did our kitchen sink 3 years ago with the flush mount that I prefer. When I asked they said that the lip tends to be finished only just a bit past the downside curve, so even a flush mount leaves a bit of the unfinished lip showing. They also said that the newer sinks they get seem to have even more scantily finished lips that the ones they got last year.
