How is it Different from a Drop-In Sink?
A drop-in sink has a lip that rests on the top of the counter. You can see around the hole in the counter how the sink connects to the surface of the counter.
An undermount sink is not seen at all above the counter. The edges are hidden from view which means that the edge of the sink blends right into the counter. It makes it very easy to just wipe crumbs or water into the sink.
