How big is your prep sink?
I need to pick our island prep sink so I can finalize the size of the cabinet under it. Many of the prep sinks we'll be looking at are 15" x 15". That seemed pretty darn big when we went to look at it in person. Our main sink will be a Kohler Stages 33 so that's really the one we'll be using for most prep tasks. The island sink is more for handwashing, island clean up, etc.
Could I live with a 12" x 10" by 5.5"? Anyone have a sink that small?
