How This Calculator Works
This outdoor fireplace cost calculator estimates your total project cost from four inputs: project size, quality tier, the options you select, and your location. It combines material and labor rates for your chosen tier, adds typical permit costs, then applies a regional cost multiplier so the estimate reflects pricing in your state.
Estimates use 2026 cost data cross-referenced from multiple industry sources. Treat the result as a planning range, not a quote. Your final price depends on your specific scope, material choices, and local contractor availability, so collect at least three itemized bids before you set a budget.
What Affects Your Outdoor Fireplace Construction Cost
Prefab Kit vs. Custom Masonry
$3,000 - $15,000A prefab outdoor fireplace insert with a simple stone surround can be built for $2,000-$5,000. A fully custom masonry fireplace built by a skilled mason from scratch costs $6,000-$20,000+. The custom option lasts longer, integrates better with your design, and holds up better to weather, but the prefab option is a legitimate and popular choice.
Wood-Burning vs. Gas
$500 - $2,500Wood-burning outdoor fireplaces require a chimney that meets code height requirements (typically 2 feet above any structure within 10 feet). Gas units need a gas line connection ($300-$1,000) and a gas insert or burner ($400-$1,500). Gas is more convenient and often preferred in urban and suburban areas. Some areas restrict wood burning outdoors.
Chimney Height and Design
$500 - $5,000The chimney must be tall enough for proper draft and to meet code. A simple prefab chimney extension costs $200-$500. A full masonry chimney adds $1,500-$5,000 to the project cost. Taller fireplaces and those on covered patios require careful chimney design to vent properly without smoking out the seating area.
Foundation and Hearth
$500 - $3,000An outdoor fireplace needs a proper concrete footing, especially in climates with frost. A simple poured footing costs $300-$800. Adding a raised hearth with paver or stone extension costs $500-$2,000. The hearth extension is both functional (ember containment) and aesthetic.
Integration with Outdoor Living Space
$1,000 - $10,000A standalone fireplace is less expensive than one that is part of an outdoor kitchen or covered patio structure. Adding a pergola or roof structure over the fireplace costs $3,000-$15,000. Integrating with an outdoor kitchen adds $5,000-$15,000. The fireplace itself may be only a fraction of a larger project's cost.

How can I lower my outdoor fireplace construction cost?
Use a prefab kit instead of full custom masonry. A quality prefab fireplace insert costs $1,500-$3,000 and installs in a fraction of the time. Add manufactured stone veneer around it for a custom look at a fraction of the price. Choose manufactured stone veneer over natural stone. The look is nearly identical from across a patio, and costs are 40-60% lower.
