When it comes to kitchen sinks, you'll be bowled over by the number of choices you have. Double-bowl sinks have been around for a while, but many folks are throwing in three-bowl-ers when they renovate. They generally have two large ones for everyday use and a smaller one just for the garbage disposal. The third bowl (however you figure it) isn't necessarily in the middle. Some models have it in the corner or on the side so you have easier access to the main bowls.
