This cabinet is designed to house kitchen sinks located in the corner of the room.

A corner kitchen sink has unique challenges: A custom cabinet has to accommodate the plumbing for the faucet to run, it must be created custom to fit that corner, and it has to connect the other two rows of base cabinets. If a kitchen designer knows there is a corner sink base, they will design around this first to make the rest of the cabinetry work with it.
