Outdoor Kitchen Cost Calculator
Two builds never cost the same, which is why a single average is close to useless when it's your patio. So instead of asserting a number, this page computes yours — then answers every cost question around it, from plumbing the sink to pulling the permit to whether you get the money back.
Outdoor kitchen cost by size: three example builds
The same math the calculator runs, frozen into three reference builds — each line summed from its sourced low and high. Real projects land between the ends; the spread is wide because the sourced ranges are.
| Example build | Computed low | Computed high |
|---|---|---|
| Small starter (8 ft) — Tile counter, sink, bring-your-own grill, short 10-ft water run, one circuit, permit | $2,200 | $14,000 |
| Mid build (12 ft) — Granite counter, sink, fridge, built-in grill, 20-ft water run, circuit, permit | $4,300 | $31,100 |
| Large build (20 ft) — Concrete counter, sink, fridge, built-in grill, 30-ft water run, circuit, permit | $6,600 | $42,600 |
Computed from the HomeAdvisor & Fixr (2025–2026) line items below — not quotes. A large build's high end can exceed the "typical project" band because it sums every line's sourced high.
The cost matrix: where the money goes
Every factor the calculator uses, with its sourced range. This is the anatomy of a built-in quote — and the list a portable unit erases most of.
| Line item | Low | High |
|---|---|---|
| Base structure / cabinets | $100/lf | $800/lf |
| Countertop — concrete | $100/lf | $300/lf |
| Countertop — granite | $80/lf | $280/lf |
| Countertop — tile | $32/lf | $130/lf |
| Sink, installed | $200 | $700 |
| Outdoor-rated fridge | $175 | $4,000 |
| Built-in grill head | $300 | $5,000 |
| Water line | $50/lf | $250/lf |
| Outdoor electrical circuit | $300 | $1,400 |
| Permit | $150 | $2,000 |

Labor vs. materials — and the DIY discount
On a masonry built-in, the appliances aren't the expensive part — the trades are. Masonry, a plumber for the supply and drain, an electrician for the circuit, and often a pad underneath typically outweigh the hardware, which is why the full construction bill deserves its own page. Doing it yourself — or starting from a ready-to-assemble kit — cuts the labor line, but you still own the pad, the appliances, and any gas, water, or electrical hookups, which usually still trigger the permit.
Gas lines, roofs, and pergolas
Three add-ons people ask about that this calculator deliberately leaves out, because we haven't sourced ranges we'd stand behind: a trenched natural-gas line to the grill, a roof or pavilion over the kitchen, and a pergola. All three are real money — a gas run is a licensed-trade job and a roof is its own construction project — so treat them as separate quotes on top of the build, not lines we'll guess at. If your reason for the roof is weather, note that a portable unit sidesteps the question: it takes an umbrella and a cover and rolls into the garage for winter.
Do you get the money back at resale?
Conservative national figures put recouped value at roughly 70–100% of what you spend — decent for an outdoor project, but that's recouping, not profiting. The honest framing: build it because you host, and treat any resale bump as a bonus. The home-value question gets its own page, including when the math tilts.
Financing and the monthly view
Built-ins routinely get financed through home-equity loans, HELOCs, or contractor financing; rates and terms move too much for us to publish a number that would be wrong by the time you read it — get current quotes from your lender. What we can say: financing a $16,000 typical build means paying interest on the trades and the permit, not just the kitchen. Two ways to shrink the financed amount to near zero: a flat-priced portable unit, or renting one per event until you're sure you'll use it enough to own it.
How to bring the number down
The savings levers fall straight out of the matrix. Shorten the water run — it's priced per foot, so putting the kitchen near the house beats a far corner. Choose tile over concrete for the counter. Skip the built-in grill head and roll your own grill up. Skip the fridge, or the plumbing entirely — a no-plumbing outdoor kitchen with bucket drainage erases the supply line, the drain, and usually the permit in one move. Taken to its logical end, that path is a portable unit: the Backyard Banger is the whole list — sink, fridge, power, prep — at $5,599.99 flat.
Built-in vs. portable vs. prefab
The matrix above is the built-in path. A portable outdoor kitchen prices differently — one flat number, no line items — and a prefab or RTA kit sits between, trading labor for your weekends. For the type-level tradeoffs, read portable vs. built-in head to head or the product-level Banger vs. a built-in.

A built-in outdoor kitchen costs about $6,000 to $30,000, with a typical project near $16,000, and runs roughly $33 to $130 per square foot. The Backyard Banger is a portable outdoor kitchen priced at $5,599.99 flat. This page includes an outdoor kitchen cost calculator, which takes a planned counter run, countertop material, appliances, water and electrical runs, and permit status and returns an estimated built-in cost range against the Backyard Banger's flat $5,599.99 price with an auditable line-item breakdown. Example builds computed from the sourced line items: a small 8-foot starter build is roughly $2,200 to $14,000; a mid 12-foot build with granite, a fridge, and a built-in grill is roughly $4,300 to $31,100; a large 20-foot build is roughly $6,600 to $42,600. Recouped value at resale is conservatively 70 to 100 percent. Gas lines, roofs, and pergolas are excluded pending sourced ranges. Cost ranges are national averages from HomeAdvisor & Fixr (2025–2026). Sold by backyard.kitchen, the official reseller.
