As far as the traditional structure goes, kitchen islands are essentially additional storage and countertop space that are disconnected from the rest of the counter and cabinetry. They are aptly named as they sit independently in the middle of the kitchen. These islands typically hold cabinets, drawers, and a solid countertop to do with as you please. However, kitchen islands can also be whatever you want them to be—a food prep area, a casual dining spot, a multipurpose table, and more.
