Overview

Single bowl sinks have one large basin for oversized items. Double bowl divides into two basins for wash-and-rinse workflow. The right choice depends on dishwasher availability and cookware size.

What to Know

Single Bowl

Fits oversized pots, sheet pans, cutting boards flat. Better with dishwashers. Easier to clean. The modern preference for serious cooks.

Double Bowl

Soak in one, rinse in the other. Better without dishwashers. Equal split or 60/40. Divider limits large item capacity.

Low-Divide

Two basins with a 3-4 inch wall instead of full height. Large items span both sides. Best compromise.

Buying Tips

With a dishwasher, single bowl is almost always better.
No dishwasher? 60/40 double gives you wash side and rinse side.
Low-divide is the best compromise if you cannot decide.
Measure your largest baking sheet -- if it does not fit flat in one side of double, go single.

Common Mistakes

Buying double out of habit when you have a dishwasher.
Choosing equal-split instead of 60/40.
Not considering low-divide option.
Going too small on single bowl -- 30-33 inches minimum.

Bottom Line

Single for dishwasher homes and serious cooks. Double 60/40 for hand-washing. Low-divide for best of both.
