How Much Does It Cost to Run a Sauna?
Many homeowners are surprised to learn that operating a home sauna costs much less than they expect.
One of the most common questions people ask before purchasing a sauna is how much it will add to their monthly electric bill. While the answer depends on the sauna’s size, heater type, local electricity rates, and how often it’s used, most homeowners find the operating costs to be relatively modest compared to the value of having daily wellness available at home.
Whether you’re considering a traditional or infrared sauna, understanding energy usage can help you choose the option that best fits your lifestyle.
Understanding Sauna Operating Costs
Every sauna uses electricity differently, but operating costs are generally determined by four factors:
- Sauna type (traditional or infrared)
- Heater size
- Session length
- Local electricity rates
Larger saunas require more energy than compact models, while longer sessions naturally consume more electricity. Fortunately, most homeowners use their sauna only a few times per week, making monthly operating costs surprisingly manageable.
Traditional vs. Infrared Energy Usage
Although traditional saunas require higher temperatures, they aren’t necessarily expensive to operate
Traditional Saunas
Traditional saunas typically use heaters ranging from 4.5 kW to 9 kW, depending on the sauna’s size.
Typical session:
- 30–45 minute warm-up
- 20–30 minute sauna session
For most homeowners, this generally works out to approximately $1–$3 per session, depending on electricity costs.
Infrared Saunas
Infrared saunas operate at lower temperatures and usually require smaller heaters.
Typical session:
- 10–20 minute warm-up
- 30–45 minute session
Because they consume less electricity, many infrared models cost roughly $0.30–$1.00 per session to operate.
What Affects Energy Consumption?
Several factors influence how much electricity your sauna uses:
- Larger saunas require larger heaters.
- Outdoor saunas may work slightly harder during extremely cold weather.
- Better insulation improves efficiency.
- Higher desired temperatures increase energy usage.
- Longer sessions naturally consume more electricity.
Fortunately, modern sauna designs are well insulated and built to retain heat efficiently.
Is a Home Sauna Expensive to Own?
For most homeowners, the ongoing operating cost is only a small part of ownership.
Many compare the monthly cost to:
- A gym membership
- Streaming subscriptions
- Running a hot tub
- Heating a small room
When viewed as part of a long-term wellness routine, many owners feel the convenience and accessibility outweigh the relatively low monthly energy cost.
The Bottom Line
Operating a home sauna is often more affordable than people expect. While traditional saunas generally use more electricity than infrared models, both remain relatively inexpensive for regular home use.
Choosing the right sauna isn’t simply about minimizing energy costs—it’s about finding the experience that best fits your wellness goals, available space, and daily routine.
