Kitchen Peninsula Ideas, Sizes and the Cabinets to Build One (With Prices)

A kitchen peninsula is a run of base cabinets and countertop that is attached to a wall or a cabinet run at one end and open on the other three sides, so it gives you most of an island's counter, storage and seating while needing an aisle along only one side.

Most peninsulas are built from two or three standard 24-inch-deep base cabinets, 4 to 6 feet of them past the corner, with a finished back, an end panel and a countertop that overhangs about 15 inches for stools. Below are the sizes, the corner and finishing parts nobody mentions until the quote, and three runs priced in Fabuwood Allure Galaxy Frost from $1,856.40 to $2,386.15, cabinets and trim only.

If you only need the one-line definition, our glossary entry for peninsula has it.

What Is a Peninsula, and How Is It Different From an Island?

A peninsula is a counter-and-cabinet run joined to the kitchen at one end, while an island stands free with all four sides open. That single attached end changes three things: the floor space it needs, how people move around it, and how many sides you have to finish.

An island needs a clear aisle on every side, which is why our island clearance guide puts the minimum room width for one at about 13 feet. A peninsula gives up the walk-around and gets its space back. In a room one aisle too narrow for an island, it usually fits exactly.

The comparison below covers the cabinet order as well as the floor plan.

A peninsula is the wrong choice when its open end would land in a doorway or across the main route into the kitchen, because every trip has to go around it. In that room, a U-shape without the return or a narrow cart usually works better.

The layout side of that choice, including when a G-shape works, is in our kitchen layouts guide. For a narrow room, the small kitchen layouts guide explains why a peninsula is often the small-room island. If you're planning a U with a peninsula closing one end, see our U-shaped kitchen layouts and plans.

How Long and Deep Should a Peninsula Be?

A peninsula with seating is typically about 41 inches deep and 6½ to 8½ feet long from the wall: a 24-inch cabinet with its door, a finished back, a 15-inch knee overhang and a 1-inch front edge, with 4 to 6 feet of cabinets past the corner. There's no code maximum on length. The real limit is the route around the open end.

Depth builds up from the cabinet. A Galaxy base box is 24 inches deep and 34½ inches tall. The door on the working side adds ¾ inch, a ½-inch finished back adds half an inch, and the front edge of the top adds an inch. NKBA Guideline 9 then asks for 15 inches of knee space per seat at a 36-inch counter, so the top lands near 41¼ inches.

Many idea guides quote a 24- to 36-inch depth or a 12- to 15-inch overhang without counting the door and the back panel. Counted properly, a 40-inch top leaves only about 14 inches of knee room, so check the drawing's top depth, not the overhang label.

Length builds up from the wall: about 25 inches of corner under the perimeter top, a 3-inch filler, the cabinet run, a ¾-inch end panel and an inch of overhang. So 4 feet of cabinets makes a top about 78 inches long, 5 feet about 90 and 6 feet about 102.

The figures below are the planning numbers we use, with the NKBA source for each clearance.

Seats go along the cabinet run, not the corner, because a stool in the corner square puts someone's shoulder against the wall. At 24 inches each, a 4-foot run takes two stools, a 5-foot run takes two with room to spare, and a 6-foot run takes three.

The aisles matter more than the length. If 42 inches in front and 32 to 44 behind won't fit, drop the seating overhang and keep a 25-inch-deep counter.

What Goes in the Corner Where the Peninsula Meets the Run?

The corner where a peninsula meets the cabinet run is an inside corner, and one of the two runs has to own it with a blind corner cabinet, a lazy Susan or a dead corner closed off behind a filler. Pick before you plan anything else, because the choice moves where the peninsula's first cabinet starts.

These are the four ways it gets solved on our quotes:

• Blind corner base in the perimeter run. The cabinet's blind section reaches into the corner under the peninsula top, and its door opens into the main kitchen. The peninsula cabinets start past it with a 3-inch filler. The Galaxy BLB36/39 is a 27-inch box that takes 36 to 39 inches of wall and costs $614.25.
• Blind corner base in the peninsula. The same cabinet turned the other way, so its door faces the working side of the peninsula. Fabuwood asks you to specify blind left or blind right when you order, and it needs a filler on the adjacent run.
• Lazy Susan. A corner cabinet with rotating shelves, the most reachable choice. It takes the most wall on both runs, which can shorten a peninsula that's already tight.
• Dead corner. Two straight cabinets meet at the corner, a filler keeps their drawers from colliding, and the space behind them is closed off. It's the cheapest option and loses about a 24-inch cube of storage.

Our blind corner cabinet guide has the pull-distance and filler math, and our corner cabinet ideas comparison prices every corner type side by side. You can browse the boxes themselves under corner base cabinets.

A peninsula that comes straight off a bare wall skips the corner: the first cabinet butts the wall and only the open end is exposed.

Which Peninsula Cabinets Should You Order?

Peninsula cabinets are ordinary 24-inch-deep base cabinets facing the kitchen, usually a drawer base nearest the cooking zone and a door base at the open end, with the back covered for seating or filled with shallow cabinets for storage. What changes is which side opens and how the hidden sides get finished.

Put drawers where the work happens. A drawer base right past the corner keeps utensils and pans one step from the range or sink, and a door base at the open end takes bulky items like mixing bowls and a slow cooker. Every box comes from the same base cabinets range as the perimeter.

The seating side has three options, and each trades storage against knee room:

• Finished back, no storage. One row of 24-inch boxes faces the kitchen, a finished sheet covers their backs, and the countertop overhangs for stools. It's the cheapest build.
• A row of 12-inch-deep bases behind. Galaxy makes full-height door bases 12 inches deep in every width from 9 to 36 inches (the -12D codes). A GF-B36FD-12D costs $477.75. The top gets deeper, so the overhang has to clear the shallow doors.
• Cabinets that open from both sides. Fabuwood's PEN-CABINET modification joins two standard base cabinets, or two wall cabinets, into one peninsula cabinet with a front on the peninsula side as well. It isn't a cart item: a designer adds it to your quote, and the Galaxy Frost spec book lists it at $295.75 net plus the two cabinets.

The double-sided cabinet has two conditions in the Allure spec book: the frame on the peninsula side must be the same size, and a full-height door on that side gets a 7-inch apron to hide the drawer box. It suits a peninsula with no seating, used as a serving counter from the dining side.

Island builds use the same parts, and our island cabinet sizes and costs guide walks through each depth combination.

How Do You Finish the Back and the End?

A peninsula's back is usually covered with a finished ½-inch sheet, and its open end gets a ¾-inch base end panel. The side against the wall or the corner stays hidden and needs nothing.

The back. A Galaxy GF-PLY-1/2 sheet is 48 by 96 inches, finished on both faces, and costs $448.50. One sheet covers a run up to 8 feet long at 34½ inches tall, so all three runs priced below use one.

For texture, the GF-BPP-12 beaded plank shows 12 inches of face per piece at $126.75 each and is trimmed on site; four cover a 4-foot back. Our island skin glossary entry covers the terminology.

The open end. The GF-BEP base end panel is 24 by 34½ inches, ¾ inch thick, finished on two sides, and costs $149.50. A ¼-inch skin, the GF-SK-BASE at $62.40, is cheaper and flush with the frame. On a peninsula end we recommend the thicker panel, because people see it head-on from the table and lean on it. You'll find both under decorative end panels.

Our skin panels and gables guide explains when a skin is enough, and the end panels, scribe molding and fillers guide covers how each piece is fitted.

The overhang end. A stock end panel stops at 24 inches, so with a seating overhang the stone hangs past it at the corner. To carry the end out to the counter edge, cut a wider panel from a GF-PLY-3/4 sheet ($516.75). It also helps support the overhang; how far stone can hang unsupported is your fabricator's call, and the bracket and corbel options are in the island guide.

What Do 4-, 5- and 6-Foot Peninsula Runs Cost?

A Galaxy Frost peninsula run costs $1,856.40 for 4 feet of cabinets, $2,080.65 for 5 feet and $2,386.15 for 6 feet, including a drawer base, a door base, the end panel, the finished back, a toe kick and the corner filler. Prices are what our live Galaxy Frost product pages charge after the 35% Fabuwood discount, checked November 6, 2026.

Each run below starts past the corner, whose cabinet is counted with the perimeter. Countertop, hardware, electrical and installation are not included.

The finished back is the item people forget, and on a 4-foot run it's almost a quarter of the bill. Storage behind costs more. Replacing the sheet on the 6-foot run with two GF-B36FD-12D shallow bases adds $507.00, for $2,893.15, and gives the seating side two 36-inch cupboards.

To see what the rest of the kitchen adds, our cabinet cost per linear foot guide shows how to price a whole room the same way.

Can a Peninsula Hold a Sink, Dishwasher or Range?

A peninsula can hold a sink, dishwasher or cooktop if it has the landing space the appliance needs and the room behind it for safety. Plumbing and power can usually come through the wall it's attached to, which makes it easier than an island.

Sink. NKBA Guideline 11 asks for 24 inches of counter on one side of the sink and 18 on the other. A GF-SB36 sink base ($490.75) with a 24-inch dishwasher on one side and a drawer base on the other fits that in about 6½ to 7 feet of run. Our sink base sizes guide matches box widths to bowl sizes.

Cooktop or range. NKBA Guideline 17 calls for 12 inches of landing on one side and 15 on the other.

On an island or peninsula, the counter should also extend at least 9 inches behind the cooking surface when both are at the same height, so a pan handle isn't over a seated guest's lap. With stools on the back, that's a deep top; many people skip seating on a cooking peninsula.

A cooktop there also needs a ceiling-mounted hood with a duct route or a downdraft unit, so choose both before the cabinet order.

Should You Hang Wall Cabinets Over a Peninsula?

Most peninsulas work best with no wall cabinets above them, because uppers there block the view and the light between the kitchen and the room beyond. Hang them only when you need the storage more than the openness, and then think about cabinets that open from both sides.

There are three ways to handle it:

• Uppers on the perimeter only. The wall run stops at the corner and the peninsula stays open above, with pendants over the seats.
• Double-sided wall cabinets. The same PEN-CABINET modification joins two wall cabinets into one that opens from both sides. Glass doors keep some of the view. If you choose open, doorless boxes, Fabuwood supplies wood shelves instead of glass ones.
• Ceiling-hung cabinets. Over a peninsula that doesn't touch a wall, the cabinets hang from the ceiling. That takes solid blocking between the joists and a support detail your contractor designs, because wall cabinets are built to hang on a wall.

Keep the same bottom height as the perimeter, usually 54 inches from the floor, or 18 inches above the counter, so the lines carry around. Our guide to hanging upper cabinets has the height pairs for each ceiling.

Does a Peninsula Need an Outlet Under the Current Code?

Under the 2023 National Electrical Code (NFPA 70), a peninsula doesn't need a receptacle, but if it has none, a provision for adding one later is required, per section 210.52(C)(2). If one is installed, it has to be on or no more than 20 inches above the counter, or in it as a listed countertop assembly, under 210.52(C)(3). A receptacle on the cabinet side below the counter no longer counts.

Earlier editions read differently. The 2020 NEC required one receptacle for the first 9 square feet of island or peninsula counter and one more for each additional 18 square feet; the 2017 edition required at least one. We haven't reviewed the newer 2026 edition's wording.

What applies is the edition your state or town has adopted, with its amendments. North Carolina's Office of State Fire Marshal, for example, issued a peninsula interpretation in October 2025 under the state's 2017 electrical code. That North Carolina ruling, not NEC text, lets a receptacle on the wall above where the peninsula connects, within 20 inches of the peninsula top, count for both the wall counter and the peninsula.

Three cabinet decisions follow from that:

• A pop-up receptacle drops into the cabinet below, so put it over the door base, not a drawer stack.
• A future-outlet provision needs a reachable spot, usually the back of the door base.
• A receptacle on the end or back panel, where your local code still allows it, should be marked on the drawing so the panel is cut once.

Kitchen countertop receptacles also need GFCI protection, and the wiring is a licensed electrician's job. The code history is in our guide to under-cabinet outlets and the 2023 code.

Which Kitchen Peninsula Ideas Work Best?

The peninsula ideas that hold up best make it do one job well, whether that's seating, storage or serving.

A contrast-color peninsula. Order the peninsula in a different finish from the perimeter, for example white Galaxy Frost on the walls and blue Galaxy Indigo on the peninsula. Both use the same Galaxy shaker door, so the profiles match, and the color marks the peninsula as furniture.

A drawer-wall working side. Two drawer bases instead of a drawer base and a door base. On the 5-foot run, a second GF-DB30 instead of the GF-B30 adds $289.25. It makes sense when the peninsula is your main prep counter.

A beaded back. GF-BPP-12 planks give the seating side a cottage look for $126.75 a foot.

A waterfall-style end. A full-depth panel cut from a GF-PLY-3/4 sheet runs from the floor to the top edge and hides the overhang. It gives a waterfall look for the price of one $516.75 sheet, and it carries the corner of the counter.

A serving peninsula with no stools. Double-sided cabinets open toward the dining table and the 25-inch top stays clear for dishes, which suits a room too narrow for seating behind.

More island-style ideas built from the same boxes are in our kitchen island ideas guide; most of them carry over to a peninsula.

Frequently Asked Questions

What is a peninsula kitchen?

A peninsula kitchen is a layout with a counter-and-cabinet run attached to the kitchen at one end and open on three sides. It usually extends an L into a G-shape or closes part of a U. See our peninsula glossary entry for the short definition.

How long can a peninsula be?

A peninsula can be as long as the room allows, since no code sets a maximum; the limit is keeping a 36-inch walkway around its open end. Most run 6½ to 8½ feet from the wall.

How much overhang does a peninsula need for seating?

A peninsula needs about 15 inches of overhang for stools at a 36-inch counter, or 12 inches at a 42-inch bar ledge, following NKBA Guideline 9. Each seat takes 24 inches of length. How far the top can hang without brackets depends on the stone and its thickness, so ask your fabricator.

Is a peninsula cheaper than an island?

A peninsula is usually cheaper than an island of the same length because it has one finished end instead of two, and its power and plumbing can come from the wall. Our Galaxy Frost runs cost $1,856.40 to $2,386.15 before the countertop.

How many stools fit at a peninsula?

Two stools fit on a 4- or 5-foot cabinet run and three on a 6-foot run, at 24 inches per seat. Plan 30 inches each for more elbow room.

Can you put a sink in a peninsula?

Yes, a sink fits in a peninsula if there is 24 inches of counter on one side and 18 on the other (NKBA Guideline 11). A 36-inch sink base, a 24-inch dishwasher and an 18-inch drawer base make a 78-inch run. Plumbing usually comes through the attached wall or the floor.

Do you need an outlet on a kitchen island or peninsula?

Under the 2023 NEC, a receptacle on an island or peninsula is optional, but a provision for adding one later is required if you leave it out. Many places still enforce the 2020 or an earlier edition, which required receptacles by counter area. Your electrician and permit office decide which edition applies.

Are peninsulas outdated?

Peninsulas aren't outdated; they are the practical answer in rooms too narrow for an island. What looks dated is heavy uppers closing off the room, not the peninsula itself.

Can you add a peninsula to an existing kitchen?

Yes, a peninsula can be added to an existing kitchen by fastening new base cabinets to the end of the current run. The corner is the hard part, since an existing end panel or corner cabinet may have to come off. The countertop usually needs a new piece seamed to the old one, or a full replacement. Order a $35 door sample first to compare against your current finish.

How long do peninsula cabinets take to arrive?

Peninsula cabinets in Fabuwood Galaxy stock finishes typically ship in about 2 weeks. Custom-paint Fabuwood finishes, including the Galaxy Designer Collection colors Macadamia Beige, Pitch Black and Pistachio Green, take typically 6–8 weeks. Cabinets are made to order and final once submitted; cancelling before production is possible only if the manufacturer accepts, with a restocking fee of typically 30%.
