How Much Does an Outdoor Kitchen Cost in Seattle? 2026 Price Guide

Outdoor kitchen cost: the 2026 numbers

National 2026 cost surveys put the typical outdoor kitchen between $5,000 and $17,300 installed, with an average around $13,200 — roughly $495 per linear foot of finished kitchen. A basic prefab island with a standard grill can come in near $3,000, while fully custom builds with masonry, stone counters and premium appliances run $40,000 and up. Size is the first lever: a compact island under 10 linear feet typically stays under $5,000, a mid-size 16-foot kitchen averages about $7,900, and large 20-foot-plus layouts start around $9,900 before appliance upgrades.

Prefab kit or custom build?

Prefab frames run about $250 to $475 per linear foot and are the fastest way to get cooking. Custom frames run $320 to $670 per linear foot — wood or aluminum framing around $400, welded steel around $550 — and let the kitchen follow your patio instead of the other way around. Finishes drive the rest: ceramic tile counters start around $6 per square foot, granite runs $65 to $75, stainless steel $75 to $100, and stone veneer on the island base adds $15 to $40 per square foot. Appliances span just as wide — grills alone range from about $180 to $8,400, and an outdoor-rated fridge adds $400 to $2,900.

What changes the math in Seattle

Three local factors push Seattle and Eastside outdoor kitchens above the national averages. First, utilities: a permitted gas line to the grill or fire feature, a dedicated electrical circuit (with a Washington L&I electrical permit) and a water line for the sink all involve trenching from the house, which is also why many clients bundle the work with a new paver patio or concrete work while the ground is already open. Second, rain: a patio cover or pergola is what makes the space usable most of the year here, and our 2026 patio cover cost guide covers those prices in detail ($25 to $40 per square foot for most covers). Third, permits: at-grade patios usually need none, but roofed structures over 120 square feet in Seattle — around 200 on most of the Eastside — need a building permit, and timelines differ city to city; see our Seattle vs. Eastside permit timeline comparison and the Washington permit guide for how long to allow.

Budgeting the whole outdoor living space

Most projects we build are more than the kitchen island. A new deck runs by its own numbers (see the 2026 deck cost guide), a paver patio is covered in our paver patio cost guide, a fire pit typically adds $250 to $2,200, and landscape lighting $2,100 to $4,900. Planning them together saves real money: one mobilization, one trenching pass for gas, power and irrigation, one permit package and one inspection schedule instead of three. It also keeps the finishes consistent — the same stone on the kitchen base, fire pit and seat walls reads as one designed space instead of a collection of projects.

When to build — and when to book

The build itself is quick: hardscape runs one to three weeks on site and a full outdoor kitchen with a covered structure three to six weeks, but permits add two to eight weeks up front and the dry-season calendar fills first. The homeowners who grill in June are the ones who designed in January. Our guide to the best time to remodel in Seattle explains the seasonal math, and winter design-and-permit work costs nothing extra.
