How Much Does a Sauna Cost? (2025)
Updated February 2025 — Backyard Sauna Pro
Sauna costs vary enormously depending on type, size, and whether you build or buy. Here is a complete breakdown of purchase price, installation, electrical, and ongoing running costs — plus where you can cut costs without sacrificing much.
Cost by Sauna Type
| Type | Purchase Price | Installation | Total Range |
|---|---|---|---|
| Portable tent sauna | $100-$400 | None | $100-$400 |
| Infrared 1-2 person kit | $700-$2,000 | $0 (plug-in) | $700-$2,000 |
| Barrel sauna (4-person) | $2,200-$4,500 | $800-$2,000 (electric) | $3,000-$6,500 |
| Indoor traditional kit | $2,500-$6,000 | $500-$1,500 (electric) | $3,000-$7,500 |
| Custom outdoor cabin | Build cost only | $8,000-$25,000 | $8,000-$50,000+ |
Electrical Installation Cost
This is the most common hidden cost for first-time buyers. Most electric sauna heaters require a dedicated 240V circuit (20-40A depending on heater size). If your electrical panel is close and accessible, electrician cost runs $500-$1,000. If the panel is far, requires a subpanel, or the work is complex, budget $1,500-$2,500.
Plug-in infrared saunas run on standard 120V outlets and require no electrical work — this is a significant cost advantage for budget buyers. Portable saunas also need no installation. The hidden cost applies mainly to traditional electric and wood-burning saunas.
Monthly Running Cost
A 6kW heater running at full load uses 6 kWh per hour. At the US average electricity rate of $0.16/kWh, that is about $0.96 per hour. A typical session includes 30-45 minutes of preheat plus session time — total run time is typically 60-75 minutes per session. Cost per session: $0.75-$1.20.
At 4 sessions per week, monthly electric cost is roughly $12-$20. Annual cost: $150-$250. Over a 15-year heater lifespan, that is $2,250-$3,750 in electricity — a small fraction of the purchase price for daily users.
Infrared saunas run on 120V and use 1.2-1.8kW. Cost per session is typically $0.20-$0.35. Much cheaper to run than traditional electric.
