Kitchen Island Cost: Custom-Made vs. Ready-Made

When in the market for a new kitchen island, you’re faced with the decision of choosing between a factory-made, ready-to-install model or a custom-built one. Let’s explore the potential cost disparities between these two options.


Custom-crafted kitchen islands generally come with a higher price tag compared to their off-the-shelf counterparts. This is primarily because they entail specific craftsmanship and meticulous attention to detail. On average, you can expect to invest between $3,000 and $5,000 in a custom-built kitchen island. However, for larger, more intricate islands boasting special features and premium materials, the cost can escalate to as much as $10,000. If your budget permits and you have a strong preference for a particular aesthetic, collaborating with a professional for a custom-made island is a worthwhile investment.

Ready-Made Kitchen Island

Prefabricated islands are a more cost-effective option since they are mass-produced. On average, a permanent prefab kitchen island typically ranges from $2,500 to $3,500 in cost. For those on a tighter budget, it’s possible to acquire a rolling prefab island for as little as $100. At the higher end of the cost spectrum, a larger prefab island complete with base cabinets can reach up to $4,000 in price.

Custom-Made VS Ready-Made Kitchen Island

Custom-Made Kitchen Island $3,000 to $10,000
Ready-Made Kitchen Island $100 to $4,000

The final expense you’ll incur for your kitchen island depends on a multitude of factors. Here are the primary variables that will factor into your budget:


Generally, as the size of the island increases, so does the cost. However, there are exceptions. For instance, selecting a prefabricated island that allows customization or necessitates assembly can yield some cost savings compared to a fully constructed or fully customized unit. Nevertheless, in most cases, a larger island will lead to a higher overall expenditure due to its larger footprint.


In addition to size, the shape of your kitchen island is a significant factor in your overall budget. Here’s an overview of the typical cost breakdown for popular shapes:

Rolling Cart

Prices for rolling cart islands range from $100 for a small, basic cart to as much as $2,500 for a larger one.


Rectangular kitchen islands typically cost between $500 and $1,500, depending on their size and any special features. This design is versatile and complements open floor plan layouts.


L-shaped kitchen islands tend to be pricier, ranging from $1,000 to $7,000. This is due to their inclusion of special features such as sinks, dishwashers, cooktops, and ample seating. The investment in an L-shaped island is justified by its versatility and entertainment potential.


U-shaped kitchen islands fall within the higher cost range, spanning from $2,000 to $9,000, and are typically custom-built. They excel in larger kitchens, offering ample space for cooking, seating, and storage, and often feature multiple sinks and cooktops.


Designed for galley kitchens, these islands cost between $500 and $5,000. Their shape is akin to a rectangular island but longer, making them suitable for various kitchen floor plans, provided there’s sufficient space.


Kitchen islands comprise various elements, including cabinetry, shelving, countertops, and storage features. The overall cost of the island is significantly influenced by the materials chosen for these components. For instance, natural stone countertops like granite or marble are typically more expensive than laminate or butcher block options. Once the island’s basic design is determined, homeowners can allocate their budget while considering factors such as quality, style, and storage preferences.


Integrating plumbing or electrical outlets for additional features can raise the cost of your kitchen island due to the associated installation and labor expenses. For example, adding appliances such as a built-in cooktop, wine fridge, or dishwasher to the kitchen island will increase the overall cost, owing to the need for extra electrical or plumbing work.


For a straightforward assembly of a primarily prefabricated island, you can estimate costs by considering the hourly rate of a skilled professional, which typically falls within the range of $40 to $140 per hour. When it comes to custom builds, you’ll likely require the services of a general contractor, who typically charges a percentage of the total project cost, ranging from 10% to 20%. In addition to this project-based fee, a general contractor may bill around $300 to $500 per day for their services, and potentially more. Each assistant or laborer may also come with a daily rate, typically ranging from $150 to $250 per day.


Hiring an electrician comes with an average cost range of $200 to $550, but actual expenses can vary significantly based on the nature and extent of the electrical work needed. Tasks such as installing light fixtures, electrical outlets, and garbage disposals require the expertise of an electrician to ensure proper wiring.


Engaging a plumber typically involves hourly rates ranging from $45 to $200, contingent on their level of experience and prevailing local labor rates in your area. If you plan to install a sink, wet bar, or any other plumbing fixture, it’s crucial to enlist a certified plumber to ensure proper installation.


The installation of gas lines comes at an average cost of $260 to $820. You should factor this expense into your budget if you intend to install a gas cooktop or a similar gas-powered feature in your kitchen island.

Kitchen Flooring

Typically, the installation of an island may necessitate repairing or addressing the existing kitchen flooring. While your chosen general contractor might include this within their services, depending on the project’s scope and impact on the current flooring, you may find it beneficial to collaborate with a dedicated flooring contractor. In certain situations, it might even be advisable to explore the option of installing entirely new flooring.

Cabinets and Countertops

If your existing cabinets and countertops are relatively recent and still align with current kitchen design trends, it’s a prudent decision to opt for a custom island with cabinets and countertops that either match or harmonize with your existing setup. Nevertheless, if it’s been a while since you last updated your kitchen, it’s worth considering the prospect of investing in new cabinets and countertops that complement your new island.

Complete Kitchen Remodel

Installing a kitchen island often serves as a component of a more extensive kitchen remodel. Depending on the scale and scope of this remodel, homeowners typically allocate budgets ranging from $5,000 to $60,000 for a comprehensive kitchen makeover. This encompasses various aspects, such as cabinetry, flooring, appliances, and overall layout enhancements, to create a cohesive and updated kitchen space.

Money-Saving Strategies for Kitchen Islands

Looking to reduce the expenses associated with a new kitchen island? Consider these cost-effective tips:

Opt for Prefab Kitchen Islands

If you come across a prefabricated island that aligns with your kitchen’s existing aesthetic, there’s often no need to invest in a custom island, especially if your kitchen layout already includes a conveniently situated sink and cooktop.

Seek Multiple Labor Quotes

Expand your options by seeking recommendations from friends, family, and neighbors for a skilled kitchen remodeling contractor to handle the installation. Collect quotes from at least three different contractors and choose the one offering the most budget-friendly bid.

Consider a DIY Installation

While installing an island can be challenging, particularly if it involves plumbing and electrical work, for the assembly of a prefab island, you may have the ability to complete the work yourself, saving on labor costs.

Handle Flooring Repairs Independently

Even if you opt not to tackle the island installation yourself, you may still be capable of handling flooring repairs independently after the island is in place. This approach can lead to substantial savings on labor expenses.
