It depends on how you and your family are going to use your sink. They have so many great options now. You can do a sink system that will give you a drain mat, or colander that will do the duty a second bowl is used for. Or you can get a sink that can be use as a single bowl AND a double bowl. ^Like Feeny said, if you have a dishwasher... I'd go with a single bowl. They are so much more useful. And I love being able to scrub the Turkey pan, and cookie sheets laying flat, instead of angled out of the sink.
