A kitchen peninsula is an extended countertop area that offers valuable seating and storage space in the kitchen. Peninsulas are secured to the floor for functionality and safety, with one end attached either to the wall or to existing counters and cabinets. Because kitchen peninsulas protrude from cabinets, they provide space to tuck chairs or stools. In most cases, a kitchen peninsula stylistically matches the main counters/cabinets to which they are attached.
