How Much Does It Cost to Run a Sauna?
Electricity costs are one of those things people forget to factor in when buying a sauna. The good news: for most people, it's less than you think. A home sauna used a few times a week typically adds $15-$40 to your monthly electricity bill. That's about the same as running a clothes dryer.
Understanding the Math
The formula is simple: heater kW x hours of use x electricity rate = cost. A 6 kW heater running for 1 hour uses 6 kWh. At $0.16 per kWh, that's $0.96 per session. Three sessions a week puts you at about $12.50 per month.
Average Electricity Rates by Region
| Region | Avg Rate ($/kWh) | 6 kW Sauna, 3x/week |
|---|---|---|
| New England | $0.24 | $18.72/mo |
| Mid-Atlantic | $0.20 | $15.60/mo |
| Southeast | $0.14 | $10.92/mo |
| Midwest | $0.13 | $10.14/mo |
| South Central | $0.12 | $9.36/mo |
| Mountain | $0.12 | $9.36/mo |
| Pacific | $0.22 | $17.16/mo |
Tips to Reduce Sauna Electricity Costs
- Insulate well. A properly insulated sauna heats faster and holds temperature with less energy. This alone can reduce costs by 20-30%.
- Don't overheat. Most people are perfectly comfortable at 170-180F. Pushing to 200F uses significantly more energy.
- Use a timer. Set the heater to turn off automatically. There's no need to keep it running after your session ends.
- Close the door. Every time you open the door, you lose heat. Plan your sessions so you're not going in and out.
- Right-size your heater. A heater that's too big for your sauna wastes energy. Use our heater size calculator to check.
