An undermount sink attaches beneath the countertop, allowing crumbs and water to be wiped directly into the bowl. Drop-in sinks rest on a rim above the countertop and can work with laminate and other materials that need the cutout edge protected. Undermount sinks require strong attachment, accurate cutout fabrication, and durable edge finishing. Sink replacement is often easier with a drop-in model because the opening and mounting are more accessible.
Key considerations
- water resistance
- cleanability
- repairability
- rimless appearance
- protected edge
- multiple sink materials
