Outdoor Fireplace Kits: Costs, Planning, and Installation

Updated September 26, 2026

An outdoor fireplace kit can become a durable patio centerpiece, but it is not a cheap shortcut. The complete project commonly includes a foundation, masonry finish, chimney components, delivery equipment, skilled labor, permits, and site work in addition to the kit itself.

What a fireplace kit usually includes

Contents vary by manufacturer. A modular kit may provide the firebox, throat, smoke chamber, and some chimney components while excluding finish stone or brick, mortar, hearth extensions, chimney cap, foundation materials, fuel components, and labor. Review the bill of materials rather than comparing only package prices.

Budget the entire installation

• kit and required accessories;
• freight, lift-gate service, unloading, or crane access;
• excavation, footing, slab, and drainage;
• masonry finish and refractory materials;
• chimney height and termination components;
• gas piping, controls, or wood-burning accessories;
• permits, engineering, and inspections; and
• labor, cleanup, and weather protection.

Site access, soil conditions, frost depth, slopes, and local labor rates can change the total substantially. Obtain written quotes before ordering.

Choose the location first

Confirm property-line setbacks, clearances from combustible construction, overhead obstructions, prevailing wind, smoke movement, seating layout, drainage, and access for construction. A heavy masonry fireplace needs an appropriate foundation; do not place it on a patio slab unless the design professional or manufacturer confirms the slab is adequate.

Wood-burning or gas?

Wood provides a traditional fire and may support cooking, but it produces smoke, sparks, ash, and creosote and can be restricted during burn bans. Gas offers quicker startup and control but requires a properly sized fuel supply, approved components, ventilation, and qualified installation.

Never convert fuels, alter a firebox, or add a burner unless the manufacturer specifically permits the configuration.

Indoor and outdoor models are not interchangeable

A product’s installation category matters. “Zero clearance” and “vent free” are technical terms tied to a particular listing and manual; they do not mean a unit can go anywhere. Verify whether the exact model is approved for indoor use, outdoor use, a covered patio, or a specific enclosure.

A current outdoor kit

The active Stone Age Standard Series Complete 36-inch Outdoor Fireplace Kit is one current option. Before purchasing, confirm what the selected package includes, the foundation and chimney requirements, finish-material quantities, freight arrangements, fuel configuration, and applicable local approvals.

You can also compare the current fireplace-kit collection, but price comparisons should use equivalent sizes and included components.

Plan for maintenance

Inspect masonry joints, chimney components, caps, drains, gas controls, and firebox surfaces on the schedule in the manual. Keep combustibles away and address cracks, water intrusion, or damaged refractory materials before further use.

Bottom line

An outdoor fireplace kit can simplify component selection, but the finished project is neither instant nor necessarily inexpensive. Choose by approved use, site conditions, complete installed cost, construction quality, and long-term maintenance.
