How Much Is a Kitchen Island with Quartz Countertops Cost?

Installing a kitchen island can be a great way to add extra workspace, storage and seating to your kitchen. Choosing quartz countertops for your island provides a durable and stylish surface. However, quartz is one of the more expensive countertop materials, so the total cost of a quartz kitchen island can add up. Here is a detailed overview of the factors that influence the cost of a kitchen island with quartz countertops.

Quartz Countertop Cost

The biggest expense for a quartz island is the countertop itself. Quartz costs $80-150 per square foot installed. With most kitchen islands ranging from 6-12 square feet, you can expect to pay:

  • Small island (6 sq ft) – $480-$900 for the quartz countertop
  • Medium island (9 sq ft) – $720-$1350 for the quartz
  • Large island (12 sq ft) – $960-$1800 for the quartz

Quartz is more expensive than materials like laminate but cheaper than premium natural stones like granite or marble. The exact price of your quartz countertop will depend on:

  • Color and Pattern: More exotic colors and patterns cost more than standard white or black quartz.
  • Edge Styles: Decorative edged like ogee, bevel, or eased cost $10-$20 more per linear foot than standard square edges.
  • Thickness: A 1.25″ thick quartz countertop costs about 20% more than 0.75″ thickness.
  • Fabrication & Installation: Countertop fabrication and installation typically costs around $40-100 per linear foot. More complex island designs cost more.

Kitchen Island Cabinetry

The cabinetry and framing for the island also represents a significant portion of the overall price. Expect to pay:

  • Prefab island: $300-$1000 for a premade stationary island.
  • Custom island: $1200-$4000 for a custom built island sized 6-12 square feet.

The cost depends on if you choose stock or custom cabinets, the materials (wood species, laminate, etc), number of drawers/doors, and additional features like pullout shelves or spice racks. High-end custom cabinetry and intricate designs will put you at the higher end of the price spectrum.

Additional Island Costs

Beyond the countertop and cabinetry, other features will also impact the total island price:

  • Seating: Stools cost $50-$300 each depending on materials. Built-in banquette seating can cost $500-$2000 to integrate.
  • Appliances: Adding a sink ($200-$600) or other appliances like a wine fridge boosts costs quickly.
  • Lighting: Task lighting and pendant fixtures over the island cost $50-$500 depending on the complexity.
  • Delivery & Installation: Having the island professionally delivered and installed typically costs $300-$1000.

Average Quartz Kitchen Island Cost

The total cost for a medium-sized kitchen island (9 sq ft) with quartz countertops typically ranges from $3000-$6000 installed. On the low end, you may spend around $3000 for a simple prefab island with laminate cabinets and standard quartz. The price goes up to $6000+ for a large custom island with high-end quartz, custom cabinetry, lighting, and accessories. Larger and more complex islands can cost $8000-$15,000 or more.

Factors That Affect Overall Quartz Island Cost

Many variables influence the all-in cost of adding a quartz kitchen island. Keep these in mind as you plan and budget:

  • Size of the island – Bigger islands cost more due to increased countertop and cabinetry needs.
  • Quartz type and edge styles – Exotic patterns and decorative edges increase price.
  • Cabinetry quality and features – Custom wood cabinets are pricier than stock laminate options.
  • Added features like lighting, seating and appliances – More features equals more cost.
  • Delivery and installation – Professionally installing the island adds fees.

Tips for Reducing Your Quartz Island Cost

If your budget is tight, consider these tips to reduce the overall price:

  • Choose a smaller island size. This cuts quartz and cabinet costs substantially.
  • Select a prefab island rather than full custom for savings on cabinetry.
  • Opt for a simpler square edge on the quartz rather than an ogee or bevel.
  • Use stock cabinets instead of custom and limit fancy features like glass doors.
  • Install the island yourself if possible rather than paying for professional installation.
  • Select a basic white or black quartz rather than exotic stone patterns.
  • Go for 0.75” thick quartz instead of 1.25” thick.
  • Limit extra features like lighting, seating, appliances, etc.

Is a Quartz Kitchen Island Worth the Cost?

While a quartz island is certainly an investment, many homeowners find it adds tremendous value and convenience to their kitchen. Quartz provides a beautiful, low-maintenance surface that can stand up to heavy day-to-day use. Investing in a quality island with quartz countertops can provide a functional centerpiece that enhances your kitchen for years to come. Carefully weigh the options above when deciding if a quartz island fits your kitchen needs and budget.

Frequently Asked Questions

How much does it cost to add a quartz countertop to an existing island?

If you already have an island and are looking to replace the countertop, plan on spending $80-150 per square foot for materials and fabrication of the new quartz countertop. You’ll also need to account for removal and disposal of the old countertop, which could be $50-150.

What thickness of quartz should I get for a kitchen island?

The standard thickness for a quartz countertop is 1.25″. For a kitchen island that won’t have as much structural load as a main countertop, 0.75″ thick quartz is usually sufficient and helps reduce cost a bit.

Can you put hot pots and pans on quartz?

Yes, quartz countertops are heat resistant and you can place hot pots, pans, and bakeware directly on the surface without damage. Prolonged exposure to extreme heat may damage the solid surface sealant though.

Is quartz or granite better for a kitchen island?

Quartz is preferable for most kitchen islands since it is less prone to staining/etching, doesn’t require annual sealing, and has more color/pattern options. Granite can provide a rich, natural stone look but requires more maintenance.

Should I get matching countertops for my island and main kitchen counters?

Having matching countertops creates a streamlined, cohesive look. However, it’s also popular to use a different countertop on the island to create a visual focal point. Contrasting colors or materials can define the island space.

Should I install the kitchen island myself or hire a professional?

If you have carpentry skills and tools, a prefab island can potentially be installed DIY. However, installing custom islands with integrated cabinetry, plumbing, lighting, etc generally requires hiring a contractor. Always get professional quartz fabrication/installation.


Adding a kitchen island with a beautiful and durable quartz countertop can cost $3000-$6000 on average. While not cheap, a well-designed quartz island provides excellent bang for your buck in terms of adding storage, seating, functionality and style to your kitchen. Carefully weigh all the cost factors and consider if investing in a quality quartz island aligns with your budget and goals for your space. With some smart design decisions, you can crafted your dream island within your budget constraints.
