## Before you buy

- The listing gives differing overall dimensions and bowl measurements, including 31"x20"x10", 20"D x 31"W x 9.4"H, 31"x20.54"x9.4", and two incompatible values labeled interior dimensions. Cabinet guidance also differs between a recommended 36-inch base and a 35-inch minimum. Confirm the actual cutout, bowl size, and cabinet requirement for this model. The cup rinser is listed among components, but the feature text says the sink has no hole for it and requires a hole to be cut if used. The title and feature text describe a drop-in sink, while some specification text describes an undermount model.

## Less suited to
