Outdoor kitchen cost = island length × frame price per linear foot + countertop area × countertop price + appliances + utility hookups. Lawn Love puts the national average at $13,180 ($495 per linear foot), with most projects $5,060–$17,280. Worked example: a 10 ft custom island with a 30 in granite top, a $2,000 built-in grill and a $1,650 outdoor fridge comes to about $8,475–$12,225.
With these inputs:
| Result | Value |
|---|---|
| Estimated outdoor kitchen cost | $8,475 – $12,225 |
| Island frame | $3,200 – $6,700 |
| Countertop (25.0 sq ft granite) | $1,625 – $1,875 |
| Appliances and hookups | $3,650 |
| Per linear foot | $848 – $1,223 |
| Frame | 10 ft × $320–$670 |
| Countertop | 10 ft × 30 in ÷ 12 = 25.0 sq ft × $65–$75 |
Building on a deck? A stone or block island with a granite top can weigh well over 100 lb per square foot of footprint; check the deck's load capacity or put the island on its own slab.
Outdoor kitchens are priced like indoor ones: the island by the linear foot, the countertop by the square foot, and the appliances one by one. Enter the island length and depth, the frame and countertop you want and your appliance budget, and the calculator totals the range, with the cost per linear foot to compare with builders' quotes.
Lawn Love puts the national average at $13,180, about $495 per linear foot, with most projects between $5,060 and $17,280. Premium appliances, long islands and new gas, water and power runs push it higher.
The island itself is about $250–$475 per linear foot prefab and $320–$670 custom-built, before the countertop and appliances. All in, the national average works out to about $495 per linear foot.
Granite ($65–$75 per sq ft) is the usual choice: it shrugs off sun, heat and frost when sealed. Concrete ($60–$95) can be cast to any shape, stainless steel ($75–$100) is easy to clean, and outdoor tile ($6–$50) is cheapest but has grout lines to keep clean.
With a custom island, a 30 in granite top, a $2,000 grill and a $1,650 fridge, about $8,475–$12,225 before any gas, water or electric runs.
Yes, with care. A masonry island and stone top are heavy, grills need clearance from combustible decking and railings, and some codes require a noncombustible pad under the grill. Lightweight steel or aluminum frames are easier on a deck; check its load capacity first.
