How Much Does It Cost to Install an Outdoor Fireplace?
Outdoor fireplace installation costs vary widely depending on design, materials, and location. In the U.S. market, published 2026 guides show ranges from $1,500 to $5,000 for prefabricated units and $5,000 to $20,000+ for custom masonry construction . These are location-specific figures—your actual quote will depend on local labor rates, site conditions, and permit requirements.
How Much Does Outdoor Fireplace Installation Cost?
Prefabricated/kit fireplaces: $1,500–$5,000 installed. These use factory-made fireboxes and chimney components, reducing labor and material costs .
Custom masonry (brick/stone): $5,000–$15,000 for standard designs, with large custom builds exceeding $20,000. This includes site-built fireboxes, masonry veneer, and full chimneys .
Gas/propane fireplaces: $3,000–$8,000, depending on whether a gas line already exists nearby .
Electric outdoor fireplaces: $1,200–$2,500, the least expensive option but limited in heat output .
Wood-burning: $2,000–$3,200 for basic prefab, $5,000–$30,000 for custom masonry. Wood-burning requires a chimney and carries higher fire-risk codes .
Material costs alone can range from $1,200 for basic brick to $10,000+ for premium natural stone . Labor typically adds $1,500–$8,000 depending on complexity and region .
What Affects the Cost of an Outdoor Fireplace?
Fireplace size: Larger fireboxes and taller chimneys require more materials and scaffolding. A 36–48 inch hearth is standard for most residential spaces .
Prefabricated vs. custom: Kits save 30–40% compared to fully custom masonry . Custom designs demand skilled masons and on-site construction.
Materials: Brick is the most common and economical veneer. Natural stone costs significantly more in both material and labor. Cultured stone veneer offers a middle ground at roughly 40% less than natural stone .
Fuel type: Wood-burning requires a chimney and firebox lined with firebrick. Gas fireplaces need a gas line run to the site. Electric units only need a power source.
Foundation and site prep: A reinforced concrete slab or footing is required for masonry fireplaces. Site clearing and leveling can add $500–$2,000 .
Chimney/venting: Wood-burning fireplaces need a full chimney (often 10–15 feet high). Gas units can use shorter vents .
Permits: Most jurisdictions require a building permit for permanent outdoor fireplaces, typically $50–$500 depending on local rules .
Prefabricated vs. Custom Outdoor Fireplaces
Prefab kits include a manufactured firebox, chimney sections, and often a simple hearth. They install in a day or two and can be faced with brick or stone veneer for a custom look. Cost: $1,500–$5,000 .
Custom masonry is built on-site by a mason. Every component—firebox, smoke chamber, chimney, and veneer—is constructed from raw materials. This allows complete design freedom but requires skilled labor and longer timelines. Cost: $5,000–$20,000+ .
Additional Costs to Budget For
– Site clearing and leveling: $500–$2,000
– Concrete foundation: $2,500–$3,000 for a 25×25-foot slab
– Gas line installation: $500–$2,500 depending on distance from supply
– Electrical work: $500+ if adding lighting or fans
– Stone or brick veneer: $1,800–$5,000+ for materials
– Seating walls or hearth extensions: $1,000+
– Permits and inspections: $50–$500
– Annual maintenance: $200–$400 for chimney cleaning and inspection
Can You Save Money on Outdoor Fireplace Installation?
– Choose a prefab kit instead of custom masonry. Save 30–40% .
