Kitchen Island Design & Installation in Columbus

Islands change how your kitchen works

A well-designed kitchen island transforms how your family uses the space. It’s the prep zone, the breakfast spot, the homework desk, and the gathering point during parties. We design seating islands, work islands, and everything between — matching your existing cabinetry, planning waterfall countertop edges, and engineering electrical and plumbing rough-ins where needed.

Seating vs work islands

The first design question is how you’ll use it. See our seating vs work island guide for a full comparison, but the short version:

• Seating islands prioritize a bar overhang for stool seating. Great for casual dining, homework, and entertaining. Usually 42 inches deep or more to accommodate seating.
• Work islands prioritize prep space, storage, and often a sink or cooktop. Deep counters, deep base cabinets, no overhang.
• Hybrid islands combine both — a wider footprint with prep space on one side and seating on the other. Best when your kitchen has the space.

Island type	Priority	Best for
Seating island	Bar overhang for stools	Casual dining, entertaining
Work island	Prep, storage, sink/cooktop	Serious cooks, extra counter space
Hybrid island	Both prep and seating	Larger kitchens with room to spare

Sizing your island

Your island only works if the traffic around it works. Our sizing rules:

• Minimum island size — 3 feet by 4 feet. Below that, the island becomes an obstacle.
• Walkway clearance — 36-42 inches on working sides, 42+ inches on seating sides. If you can’t meet minimums, don’t force an island.
• Overhang — 12 inches minimum for casual seating, 15 inches for comfort. Support with corbels or steel brackets on longer overhangs.
• Height — 36 inches (counter height) or 42 inches (bar height). Counter-height is more common and works with regular kitchen stools.

Electrical and plumbing

Islands often need utility rough-ins, and those decisions have to be finalized before the island is built. We coordinate:

• Outlets — most codes require at least one outlet on any island above a certain size. We run these to code, with GFCI where required.
• Prep sinks — plumbing rough-in through the floor. Vented per code.
• Cooktops — 220V circuit or gas line depending on the appliance. Ventilation via downdraft or ceiling-mount hood.
• Task lighting — under-counter LEDs, pendant lights, or recessed lights above.

See our island electrical and plumbing guide for a fuller breakdown.

What drives island cost

Most islands are priced as a package: base cabinetry + countertop + install + any utility rough-ins. The main cost drivers:

• Size — bigger island, more material, more labor.
• Countertop material — quartz vs granite vs marble vs butcher block. Waterfall edges add 30-50% to countertop material.
• Storage complexity — drawers, pull-outs, pantry inserts add cost but often pay off in daily usability.
• Utility rough-ins — plumbing and electrical add both material and coordination cost.
