Kitchen islands have become a must-have feature in modern homes. They’re more than just extra counter space — they’re the heart of the kitchen, where families gather, kids do homework, and guests linger over wine. But before you commit to adding one, it’s important to understand the cost to install a kitchen island.
The price can vary widely, from a budget-friendly work surface to a fully customized centerpiece with seating, storage, and appliances. Let’s break down the 7 key factors that influence the cost so you can plan your remodel with confidence.
1. Size and Layout
The bigger the island, the more it costs — plain and simple.
-
Small prep island: $3,000–$5,000
-
Medium island with seating: $7,000–$12,000
-
Large custom island with appliances: $15,000–$20,000+
Size affects not only the amount of material needed but also how much labor is required for cabinetry, countertop installation, and even flooring adjustments.
2. Cabinetry Choices
Cabinetry is often the biggest cost driver in a kitchen remodel, and your island is no exception. Options include:
-
Stock cabinets: Affordable, but limited in size and style.
-
Semi-custom cabinets: Greater flexibility in finishes and dimensions, with mid-range pricing.
-
Custom cabinetry: Tailored to your exact kitchen and design vision, but expect a higher price tag.
On average, island cabinetry accounts for 30–40% of the total island cost.
3. Countertop Material
Your countertop choice can dramatically swing the budget. For a standard-size island:
-
Laminate: $500–$1,500
-
Granite/Quartz: $2,000–$5,000
-
Quartzite/Marble: $4,000–$8,000+
Waterfall edges (where the countertop extends down the sides) add a luxurious look but also increase fabrication costs.
4. Appliances and Plumbing
Adding a sink, dishwasher, or cooktop introduces plumbing and electrical work — both of which add complexity and cost. For example:
-
Sink installation: $400–$1,000 (plus plumbing).
-
Cooktop or range: $1,500–$5,000.
-
Electrical outlets: $150–$300 each (often required by code).
The more functions your island serves, the higher your installation costs will climb.
5. Seating and Overhang
Many homeowners want an island that doubles as a casual dining spot. To achieve this, you’ll need a countertop overhang (typically 12–15 inches) and sturdy cabinetry to support it.
While the extra material cost may be modest, adding seating often means a larger island footprint, which influences cabinetry and countertop expenses. Factor in barstools, and your budget rises slightly more.
6. Finishes and Extras
Design details can make your island a showstopper — but they also affect cost. Popular upgrades include:
-
Decorative panels or furniture-style legs.
-
Built-in wine racks or open shelving.
-
Accent lighting, like pendants or under-counter LED strips.
Even small finishing touches can add $500–$2,000 to the final price.
7. Labor and Installation
Never underestimate the cost of skilled labor. Professional installation ensures your island is structurally sound, level, and properly connected to plumbing and electrical systems.
Labor costs vary by region but typically account for 25–40% of the total project cost. A professionally built and installed island may cost more upfront, but it saves money long-term by avoiding mistakes and repairs.
What’s the Bottom Line?
On average, the cost to install a kitchen island falls between $5,000 and $15,000.
-
A simple island with stock cabinets and a laminate top will be on the lower end.
-
A large custom island with premium countertops, appliances, and seating can exceed $20,000.
The best way to control costs is to clearly define your priorities: storage, statement design, or multi-functionality. By working with a skilled designer, you can balance your wish list with your budget.
