Why a 3 compartment sink

Health codes require a three compartment sink for washing dishes by hand: one bowl to wash, one to rinse and one to sanitize. Even kitchens with a dish machine usually need one for pots, pans and equipment that will not fit the machine.

How to choose

Bowl size

Each bowl should be big enough to fully submerge your largest pot or sheet pan. Common sizes are 10" x 14", 14" x 16", 18" x 18" and 24" x 24". Bowl depth matters too: 12" to 14" deep is standard for pots.

Drainboards

Drainboards give dirty and clean dishes a place to land. A left drainboard for dirty and a right drainboard for clean (or both) keeps the workflow moving in one direction. Models like the S3C-181812-RL-NF (90" x 24") and S3C-242414-RL-NF (120" x 30") have drainboards on both sides; the S3C-181812-NF (59") and S3C-141612-NF (47") have none.

Overall length

Measure the wall. Bowl size and drainboards together set the overall length, from about 36" for a compact drop-in to 120" for a full dish station.

Faucet and accessories

Most sinks need a faucet with 8" centers, and a pre-rinse faucet saves time at the scrap end. Check each listing to see what is included.
