Cost by Project Type
Infrared Saunas
Prefabricated infrared cabins use infrared panels to heat your body directly rather than heating the air. Most models come pre-wired and plug into a standard 120V outlet. Installation involves assembling the panels and ensuring adequate ventilation in the room.
Why it costs what it does: Infrared saunas are the most affordable option because they require no custom construction, no 240V electrical work, and minimal ventilation modifications.
Best for: Best for homeowners who want a simple, low-maintenance sauna that fits in a spare room, basement, or large closet.
Prefab Indoor Finnish Saunas
Factory-built sauna kits with pre-cut cedar panels, benches, heater, and controls. A licensed electrician installs a dedicated 240V circuit for the heater. The sauna is assembled inside an existing room with appropriate ventilation.
Why it costs what it does: Mid-range pricing reflects the 240V electrical requirement and the higher-quality construction materials (western red cedar, proper insulation) compared to infrared units.
Best for: The most popular choice for homeowners who want an authentic Finnish sauna experience without the cost of a custom build.
Outdoor Barrel Saunas
Cylindrical cedar saunas designed for outdoor placement. Delivered partially assembled and installed on a level gravel pad or concrete base. Require electrical hookup for the heater and may need a small deck or pathway.
Why it costs what it does: Barrel saunas cost more than indoor prefabs due to weather-resistant construction, delivery logistics, and site preparation. No structural framing is needed.
Best for: Ideal for homeowners with yard space who want a dedicated outdoor wellness area without a full custom build.
Custom-Built Sauna Rooms
Built from scratch inside or outside your home. Includes framing, vapor barrier, insulation, cedar lining, benches, heater installation, ventilation, and lighting. Indoor builds may require modifying existing walls.
Why it costs what it does: Premium pricing reflects full construction labor, custom materials, and the complexity of integrating a sauna into an existing home structure.
Best for: Best for homeowners who want a specific size, layout, or design that prefab options cannot accommodate.
What Affects Home Sauna Installation Costs?
Sauna Type & Size
Infrared saunas cost the least. Traditional Finnish saunas with electric heaters cost more. Size matters — a 2-person sauna costs significantly less than a 4-6 person model due to materials, heater size, and electrical requirements.
Electrical Requirements
Most traditional saunas need a dedicated 240V circuit ($500–$1,500 for electrician work). Infrared models often run on standard 120V. If your electrical panel needs an upgrade, add $1,000–$2,500.
Indoor vs Outdoor Placement
Indoor installations use existing structure but may need ventilation modifications. Outdoor builds require a foundation, weather-resistant materials, and possibly a covered entry — adding $1,000–$3,000 to the project.
Materials & Wood Species
Western red cedar is the standard choice for saunas. Thermally modified wood, hemlock, and basswood are alternatives at different price points. Premium wood species and thicker benches increase cost.
Ventilation & Drainage
Proper ventilation prevents moisture damage to surrounding structures. Indoor saunas need intake and exhaust vents. Outdoor saunas may need drainage planning. Inadequate ventilation is a common source of problems.
Permits & Inspections
Outdoor sauna structures and new 240V electrical circuits often require permits. Permit costs vary by municipality ($50–$500). Your installer should handle permitting as part of the project.
