I have encountered a couple of different accepted appearances for undermount sinks in a solid surface counter-top. One way is to cut the opening a little larger than the inside perimeter of the sink bowl ( given a generous enough flange). The other way is to cut the opening smaller than that perimeter by around 3/8″ to 1/2″ and therefore have the counter surface overhang the interior of the bowl.
In the first method the cut-out is large enough so that the flat of the flange is against the edge of the cut-out, so that there is a nice crisp joint which then requires clear silicone caulking. With the overhang method you don’t even see the round over at the top of the sink bowl, although the joint between the counter and the sink still must be caulked.
I have done this both ways myself and I personally prefer the look of the overhang installation, but I’d love to get some general feedback on the subject.
