The choice comes down to how you do dishes and how much countertop real estate you want to dedicate to the task. A single-basin sink takes up less space, but often provides more room to work on scrubbing a large pan. Even though double-basin sinks are bigger, each basin tends to be smaller than the one basin found on a single-basin sink. But a double-basin does offer a few advantages. First, you can soak cookware overnight in one basin and still have a second basin free for other tasks. You can also fill one basin with suds and the other with clean water, so you can wash and scrub on one side and rinse on the other. Lastly, if you don’t have a lot of dishes in the first place, a double-basin sink outfitted with a small dish rack on one side might be ideal, since it can take up less space than a single-basin sink and a dedicated dish rack on the counter.
