Kitchen island or peninsula? How to decide

Everyone wants an island, but not every kitchen has room for one. A peninsula, attached to the cabinets on one end, often gives the same counter and seating in less space.

Space needed

An island needs about 42" to 48" of clearance on every side. A peninsula needs clearance on three sides, so it fits kitchens roughly 3 feet narrower. Check with the island fit checker.

Traffic flow

Islands let people walk around both ends, good for two cooks and open plans. Peninsulas create a U or G shape that keeps guests out of the work zone.

Seating

Both can seat people along the overhang. Plan about 24" per stool; see the island seating calculator.

Cost and plumbing

A peninsula ties into existing cabinets and is often cheaper, especially when it holds the sink or dishwasher near existing plumbing. Islands with sinks need plumbing run through the floor.

Try both

Sketch both in the kitchen layout planner, or read the kitchen island guide.
