If it's been a while since you shopped for a kitchen sink, you'll find there's now a world of different kinds to choose from. There are stainless steel sinks, double well sinks, fireclay sinks, concrete sinks with integrated draining boards and copper farm sinks, just to name a few of the many styles available. Probably the first decision most buyers make is to determine whether they prefer a single well or a double well. These are the two main configurations. Triple well models are also available, along with specialty styles like trough sinks and integrated drain-board sinks.
