If you want to make your kitchen layout more versatile, functional, and attractive, adding a kitchen island can help. In a recent survey of experts, Fixr discovered 92% of homeowners prefer a kitchen island layout over any other design.

Kitchen islands can be small and designed for extra storage or large with built-in seating and cooking areas. They may contain sinks and appliances or more counter space. They come in many materials and countertop options, complementing any kitchen design.

There is a large cost range for kitchen islands. The national average for a kitchen island installation is $3,000 to $7,000, with most homeowners paying around $5,500 for a 24 sq.ft. semi-custom island with a granite countertop and bar sink, with enough space for seating on one side. Readymade rolling islands with wood countertops cost $500. At the high end, you can get a fully custom exotic hardwood island with an antiqued glaze and waterfall marble countertop with a cooktop, seating area, and built-in shelving on one side for $12,000.

Designing Your Kitchen Island

The kitchen island was originally introduced to add more countertop and storage space to a kitchen. As kitchens become larger, the working triangle - or the distance between the sink, refrigerator, and cooktop - grows larger. This makes some oversized kitchens difficult to work in when the appliances are relegated to the perimeter. By putting one component of the working triangle into the island, you bring it down in size, making the kitchen more functional. The island can become a landing zone for the refrigerator, house the main sink or cooktop, or provide seating and bar sinks or wine fridges.

When designing your island, consider how the island will be used. If you need it to make the working triangle smaller, consider which piece of the triangle moves. If you move the sink, it is beneficial to also move the dishwasher. If you move the cooktop, where does this leave the oven? On the other hand, if you want to use your island for cooking and baking prep, leaving it mostly bare with only a prep sink may be the right choice. If you need seating, reconfigure the island’s layout, and if you want to use it for storage, consider how you store items. Islands can have open shelving, oversized drawers, or simple cabinets. The layout you choose needs to meet your workflow.

The island should also fit your kitchen design. The island can match your perimeter cabinets and countertop in color, style, and material, or you can choose to contrast or complement it. Some people like to use the island to introduce color, others make it the focal point of the design and use more elaborate cabinetry or a more eye-catching countertop, while leaving the room perimeter plain. These features impact your island’s cost, and the more customization you choose, the higher the ultimate cost.

Kitchen Island Prices by Type

Design professionals often describe islands using terms associated with their function. There are prep and wash islands, seating, cooking, and more. There are islands with open shelving on one side and seating on the other. Some have cabinetry, bookshelves, and wine storage.

Your options are limited with prefab models, although a good handyman can often make adjustments during installation. If you want a more detailed and accessorized kitchen island, design it from scratch. If you design from scratch, find a starting point for your island. The following types of islands should narrow your focus to the layout that works best for you.

Kitchen Island Prices

Storage Island

Storage islands are the most simple, consisting of the cabinetry and a countertop. They could be an island cart with a built-in butcher block countertop or an elaborate and customized island with wine racks and specialty organizers. They can have open shelving or be made entirely of cabinets, or have a mixture. You can find prefab, ready-to-install storage islands, or have one custom made. Prices range from $500-$5,000, depending on the design, material, and construction.

Island with Seating

If you do not have an eat-in kitchen and want to accommodate your family or have seating for guests, island seating is a great addition to your space. Island seating does not change the island all that much. You can have a storage island or have a bar or entertainment sink added, and the island can have open shelving or cabinets. However, the countertop needs to overhang on one side by at least 12 inches to accommodate legroom. To fit the island in the space, you need to shrink the cabinetry portion. You need a minimum of 36 inches of clear space around the island to pass code, and that includes seating. Many people choose to use corbels that match the island to accommodate the countertop overhang, raising your base price slightly. An island with seating usually costs between $750 and $5,000, depending on the design.

Prep and Wash

A prep and wash island has a larger sink and more space for working. It is designed to make dinner prep and clean up easier and a good choice for kitchens where the working triangle needs to move the sink to the island. You can include a dishwasher in this design or opt for a small bar sink and faucet to add function. These islands can still be found in stock cabinetry but are much more likely to be a semi-custom or custom design. Pricing ranges from $1,000 to $5,000, depending on the design.

Working Island

This is a common option and usually includes a sink and faucet with the materials and design fees. You may need to calculate the costs of a plumber who can install a drain, run plumbing through the island, and install a sink and faucet set. This can make the island more costly, but it will be a great deal more functional because you can prep, clean, and cook thanks to the sink and faucet. It could be designed for special functions like pastry preparation and feature a marble work surface for dough rolling. You can still find stock islands that work with this use, but you are more likely to get what you want from a semi-custom or custom design. Pricing ranges from $1,000 to more than $5,000, depending on the options.

Cooking Island

A cooking island is one of the most popular kitchen island layouts, adding either a cooktop or full range. This makes the working triangle more user-friendly, and smaller galley-style counter sections have more landing area for the cooking zone. Like the cooking area on the kitchen’s perimeter, a cooking island needs to have enough landing area on either side to meet code. These islands tend to be larger than others, and they need to accommodate the gas or electrical hookups necessary for the cooktop or range. At this point, stock cabinets are no longer an option, and you need a semi-custom or custom design. Pricing ranges from $1,000 to $7,000, depending on the size, material, and features.

Consult with a pro when purchasing a kitchen island

Kitchen Island Cost by Style

For many people, the style and shape of your island is nearly as important as the function. Your island can complement the color, cabinet style, countertop, shape, and layout of the rest of your kitchen, or they can contrast. Part of this should increase the functionality of the space, particularly if you are using your island to help close the distance between your sink, stove, and refrigerator.

Islands come in nearly any shape or size, even freeform if you desire. The most common are made to increase function so that they meet your needs.

Rolling Cart Island

If you do not have the budget or space for a permanent island, but you want more storage or workspace, a rolling cart island is a fantastic addition. This is a readymade island on wheels. It may have cabinets or open shelves, and most have a butcher block top. You can push them to the side or into a closet when not in use, and they come in many sizes. They cost between $100 and $1,000, depending on the size and style.

Rectangular Island

A rectangular island is a good choice for many kitchens. If your kitchen is a galley, L-shaped, or U-shaped, a rectangular island fits in nicely. This is also a nice choice for open floor plans because it divides the kitchen and the adjoining space. These are simple islands, and depending on the size, they can have sinks, seating, or cooktops. They cost between $500 and $5,000, depending on the size, style, and purpose.

Galley Island

The galley island is a long, thin rectangular island. It is meant to be added to galley kitchens to give some additional counter and cabinet space. They are about the same size and shape as a perimeter cabinet run and can create a partition in an open floor plan. They cost between $500 and $5,000 on average.

L-shaped Island

The L-shaped island is good for bigger or galley kitchens in an open floor plan because they have more storage and layout options. The L-shaped island allows seating on the short end, with a sink and prep area on the long end. Or, it allows for counter space on one section and a cooktop on another. Because this island needs more cabinets to construct, it costs between $1,000 and $7,000. You can fit two stock islands together with one countertop to cheaply imitate this style.

U-Shaped Island

The U-shaped island is less common, but if you have a galley kitchen in an open floor plan and need the island to pull double or triple duty in the kitchen with a sink, cooktop, or seating and storage, this is the shape for you. Keep in mind that the U-shape does not have to be symmetrical or have deep “wings” on either end. You can make this style with three pieces of stock cabinetry or have it custom designed. Because you need more cabinetry, it costs between $2,000 and $9,000 on average.

Furniture-Style Island

Furniture-style islands are attractive, eye-catching pieces meant to be the focus of the kitchen. Most furniture-style islands are readymade. They come in various set sizes, colors, and designs made to look like a piece of movable furniture. They are usually open, have legs or feet, rather than sitting on a cabinet base, and are highly decorative. They are often smaller and cannot accommodate as many features as other islands, but they make very attractive additions. They cost between $2,000 and $9,000 on average.

Circular Island

If you want to create a modern and interesting design for your kitchen island, consider an oval, rounded, or circular island. These islands have a very contemporary look. The lack of sharp angles gives a fluid appearance that contrasts nicely with the cabinets in the room. To create this island, special types of bendable wood and wood veneer are needed. Any countertop you use has to be cut to fit, and this raises the cost. Circular islands typically cost between $3,000 and $10,000, depending on the size and material.

Kitchen Island Pricing by Countertop Material

You also need to choose a countertop. Some islands come with a countertop already, particularly stock islands. If you choose a semi-custom or custom island, you need to purchase a countertop separately after the island is installed. If you install a sink or cooktop on your island, these need to be on hand. A template of your island and any sinks or cooktops is made so that the countertop can be cut to fit. There are many countertop materials to use on your island, and each has a separate cost. While it is common to use the same material installed on the perimeter cabinets, it is unnecessary. You can also mix and match to create a unique design. Countertops may be made of any color of stone, metal, laminate, or tile like they can be for the perimeter cabinets. Below are the average costs for the most popular island countertop materials. Also included are the cost ranges for an island with that countertop, assuming an average island size of 24 sq.ft. and a base cost of $3,000.

Ceramic Tile


















Stainless Steel






Ceramic Tile Kitchen Island

Ceramic tile comes in many colors, shapes, sizes, and finishes. It is one of the least expensive ways to tile a countertop, whether that counter is for the perimeter cabinets or your island. Assuming a base cost of $3,000 for a basic wood island without many accessories, installing a ceramic tile counter costs $600 - $720, assuming an average cost of $25 - $30/sq.ft to factor in edging, grout, and mortar. This results in a total materials cost of $3,600 - $3,720.

Laminate Kitchen Island

Laminate is not the most frequently used material for an island because you need to have it custom made. Islands have an edge that goes completely around, and all those edges must be finished with laminate, which means the costs start to approach other materials. Assuming a base cost for an island of $3,000, add about $720 - $960 for the counter, making a total cost of $3,720 - $3,960.

Butcher Block Island Cost

If you purchase a stock kitchen island, it most likely comes with a butcher block top included at no additional cost. However, if you are using a semi-custom or custom island base, it is possible to add a butcher block island for around $480 to $7,200, making the total costs for a basic island between $3,480 and $10,200.

Marble Kitchen Island Cost

If you bake, you may want to consider a marble countertop for your island because marble makes the ideal material for rolling out dough. Marble slabs are often large enough to cover the average size island. Marble slabs are typically smaller than other materials, so if you have a large island, you may need more than one slab. For the average-size island, marble tops cost between $960 and $4,800, making your total costs between $3,960 and $7,800.

Quartz Kitchen Island Cost

If you want a low-maintenance slab countertop for your island, consider quartz. Quartz countertops are made from roughly 90% natural quartz stone and 10% resin and pigment. They are virtually impervious to everything and come in many colors and styles. They have a cost range for the average island of $1,320 to $4,800, making the average island cost between $4,320 and $7,800.

Cost of Kitchen Island with Granite

Granite is one of the most popular materials for kitchens. It comes in a nearly endless array of colors and styles, and it is highly durable. Granite islands can match or coordinate well with a variety of perimeters, including other materials. The average granite island countertop costs between $1,800 and $12,000, making the average kitchen island with granite cost between $4,800 and $15,000.

Stainless Steel Island

Stainless steel makes an excellent material for kitchens. If you have a contemporary kitchen, you can opt for an island made entirely out of stainless steel or another material, which has a stainless steel countertop. The average stainless steel counter costs between $1,920 and $4,800. If you choose a stainless steel island, expect total costs between $6,920 and $9,800. Melamine or MDF cabinets cost closer to $4,920 and $7,800.

Copper Kitchen Island

A copper countertop for your kitchen island can bring a new level of depth to your kitchen design. Copper has a living finish, which ages according to how it is used and touched. Places frequently interacted with remain bright and polished, while places that are interacted with less frequently become darker and duller in color. The average copper countertop for an island costs between $2,400 and $4,200 for a total average cost of $5,400 and $7,200.

Waterfall Island Cost

A waterfall island is a beautiful statement in any kitchen. It is done by taking a slab countertop, such as granite, marble, or quartz, and creating a 90-degree angle with the slab to continue down one side. The side covered by the slab is not accessible, so your island’s layout needs to include one blank side, rather than having shelves, drawers, or drawers all the way around. The average slab countertop cost for a waterfall island is $3,600. This could be higher or lower, depending on the material. This costs approximately $6,600 for an average-size island. Larger islands or islands with many accessories cost more.

Kitchen Island Base Cabinets Prices

The material you build your island out of, including the cabinet doors, drawer fronts, and basic box, varies widely. You can find stock cabinets in many materials and styles or design a custom or semi-custom island with any of the same materials you would use for custom kitchen cabinets. The most readily-available materials are oak, maple, cherry, birch, pine, walnut, and laminate, but you can find more if you work with a custom cabinet builder. Like all materials, each option has a range of costs. These costs are for the basic material and do not include finishes, accessories, or installation.

Cost to Install a Kitchen Island

Installing your island can be an easy project if it is a simple furniture-style or storage island. On the other hand, it can be an incredibly complex project if it involves running a gas line, a stove installation, or pipe running.

Your kitchen contractor will likely charge a flat fee for the installation. This is a base rate of roughly $100 per “cabinet” that makes up your island. So, a 24 sq.ft. island may have 6 cabinets and cost around $600 to install. The cost of your countertop installation is usually included in the cost of the material. If this is a basic, storage, or seating-style island, this is all that is necessary.

However, when installing a sink, you need to add in the cost of a plumber at $45 to $200, with the average cost to install a sink being around $400. When installing a dishwasher, add another $325 to $450. Installing a cooktop adds $1,500 to your costs, and if you need a gas line run to the island, this costs about $200 for a gas line extension. If you are installing an electric cooktop, you need to hire an electrician at a rate of $40 to $120 an hour.

When adding a cooktop, you need to add a range hood above the island. This costs $300 to $900. It is common to have outlets installed in islands, which costs around $274 for a GFCI outlet.

For a 24 sq.ft. wood, semi-custom island with a granite top and a small bar sink, the labor portion of $5,500 total would be around $800.

Custom Kitchen Island Cost

There are three basic types of kitchen cabinets and islands. Stock cabinets and islands that are readymade. You can find them at any big box store or any home goods website. Many stock cabinets come with a counter and are designed for easy, DIY install.

Semi-custom cabinets and islands are ordered from the cabinet company directly. This allows you to change the color and some of the door and drawer styles, but the main box of the cabinets and islands remains the same.

Custom cabinets and islands are built just for you. You can customize them to the inch and include any number of details and accessories. They also cost the most. A stock island costs $500 for the entire island and countertop, and a semi-custom island may have starting costs of $50 a linear foot. Custom island costs start at $300 a linear foot. This does not include the countertop, which needs to be purchased separately.

Cost of a Kitchen Island with a Sink and Dishwasher

If you want an island installed with both a sink and dishwasher, expect to pay around $3,000 for the island and $600 for its installation. Add another $1,000 - $2,000 for a slab countertop, $400 for the sink and its installation, and $325 to $500 for an installed dishwasher. This makes the average 24 sq.ft. island with a sink and dishwasher cost an average of $5,325 to $6,500. Your costs could be much higher or lower, depending on the island materials and size, sink, and dishwasher.

Kitchen Island Seating

To determine how custom options affect the cost, consider the individual variables. Seating means having adequate countertop space for stools or a taller bench. This means you have to purchase seating. This might be a basic, prefabricated counter stool of roughly 27” in height and costs $10 to $800. Customized options range from $800 with a prefab island to over $5,000.

Kitchen Island Accessories

One of the best things about islands is how customizable they are. With accessories, you can outfit your island with shelving, bins, racks, and organizers to make your kitchen as functional as possible. The following accessories are optional, meaning you can choose to add none or all, depending on your needs.

Kitchen Island Pros and Cons

Kitchen islands bring function and style to the kitchen. They shrink your working triangle and make it easier to use. They can add more storage, seating, or workspace to a kitchen and make entertaining easier. Islands introduce more colors, textures, and styles into your kitchen, enhancing the space’s appearance.

But adding an island robs your kitchen of floor space. You need between 36 and 41 inches around the island on all sides. For smaller kitchens, this dramatically limits the size of the island you can have. In some layouts, islands can also make the kitchen feel cramped. The island may block the flow of traffic and make it hard to navigate the space.

Enhancement and Improvement Costs


An energy-efficient refrigerator averages $800-$1,000, and there may be delivery and disposal fees. If installation is not included, the price of installation averages $370.

Pet Stations

Pet stations are popular cubbies designed for pet feeding dishes or pet supplies. They can be incorporated into the actual design, or a lower shelf can create one for an affordable improvement.

The costs for a pet station vary too much to make a realistic estimate here, but you can calculate a basic cost. The price is based on the materials you choose, the amount of time the designer commits to this aspect, and whether you make it a distinct feature or create it out of the island’s pre-existing design. The pet station is typically 30% of the kitchen island’s cost.

Range Hood

If you add a cooktop or range to your island, you need to add an island range hood. These are vents suspended from your ceiling. Some cooktops offer a downdraft vent option, but ranges are more effective at removing smoke and cooking smells from the area. The average island range hood costs between $300 and $900.

Oven Installation

While cooktops are the most common addition to islands, you can also choose to put an oven there. Ensure you have enough room on the island to accommodate the opening of the oven door, and that the island is large enough to have a landing area on either side. Oven installations cost around $1,800 on average.

Additional Considerations and Costs

  • If you want to save money or cannot afford a professionally installed kitchen island, big box options include workbenches and kitchen carts ($60 to $400). You can easily retrofit one to your space, replace the work surface with a better custom ordered top, and rely on this until you can afford the larger project.

  • State and local laws dictate if your kitchen island project requires a permit. The electrical and plumbing work need a permit, but building codes might also require permits also. The prices vary from $366-$1,340.

  • Features on your kitchen island should make sense from a layout and use standpoint. Keep in mind that moving something, such as a dishwasher, to the island will boost your total cost. If the move is not going to improve the function or layout, it may be best avoided.

  • Your location may impact the cost of materials, labor, design, and even accessories. Local dealers have different costs than online vendors, and area contractors and contractors coming in from a different location may also have different prices.


  • Where is the best place to put your kitchen island?

Anywhere you can ensure 36" on all sides for safe traffic to pass, and this includes if you put one end against the wall. You must allow 36" on all other sides.

  • How to install a kitchen island?

This is done with carpentry that ensures the cabinetry has a kick plate, and is fixed to the floor. The base has to be professionally assembled and the countertop mounted and secured. Any plumbing or electrical is to be done before and after the actual island is installed.

  • How much does it cost to get your kitchen island installed?

This is going to depend upon the amount of work required, but carpenters average $100 per hour and you may need the work of electricians at $75 per hour and plumbers at $55 per hour. Most installations take more than a single day and can be part of a remodel.

  • Which are the most resistant counter materials?

Stainless steel cannot burn, crack, or be easily damaged. If you want a more natural material, quartz is very strong and many laminates are resistant to burning and wear.

  • How large should be the walkway clearances?

At least 36", but a minimum of 42" if you have appliances with doors within the walkway area.

  • How much is a granite countertop per square foot?

The cost of this popular material is from $75-$400 per square foot.

  • How much does it cost for a kitchen?

The cost for a typical kitchen renovation is around $20,000.

  • What is an island in the kitchen?

An island is a key part of the cooking space. It is a multi-purpose unit that improves any kitchen's function and appearance. It can be used for seating as well as food prep.
