 And here's what you want to think about when you're cooking in zones. You have your prep area, which is usually the place between the sink and the cooking surface. So if you've got an L-shaped kitchen, that area between the sink and maybe the range of the cooktop is the important part. That's the prep area. That's where you're most likely to prep. The last thing I want to do is put the dishwasher in that area because that's the cleanup zone.
