What is the difference between an undermount sink, a self-rimming sink, a drop-in sink and a sink/countertop combo?
Whether in kitchen or bath self rimming sinks can be used with any type of countertop and mount on the surface of the counter. Undermount sinks can only be used with solid countertop materials, such as Corian, granite or marble. The sink is mounted underneath the slab of the countertop for a smooth, clean look on the countertop. Unfortunately, this sink is not seamlessonly a Corian sink bonded to a Corian countertop is seamless. The undermount sink moves the seam between sink and counter to a place that is hidden between the two surfaces. For homeowners who are primarily concerned with sanitary surfaces, the self-rimming sink is the better choice over undermount because the joint between the two surfaces is visible. For the Easy Clean as Top Priority Folks, a Corian Sink bonded to Corian deck is almost in a “self-cleaning” category.
