How much does it cost to run an infrared sauna?

For a typical 1–2 person infrared sauna drawing about 1,600–1,800 watts, a 45-minute session uses roughly 0.8–1.3 kWh once you account for the heaters cycling on and off (about a 70% duty cycle). At the 2026 U.S. average residential rate near $0.17 per kWh, that is roughly $0.15–$0.25 per session, or about $3–$5 a month at four sessions a week. Higher electricity rates or larger, higher-wattage cabins push the number up. Use the calculator to get a figure for your exact sauna, session length, and local rate.

Does a home infrared sauna save money versus a spa membership?

Usually, if you use it regularly. A spa or gym sauna membership commonly runs $1,200–$2,400 a year, and drop-in studio sessions far more, while a home infrared sauna costs only a few dollars a month in electricity to run. Once the electricity savings exceed the one-time purchase price, the sauna has paid for itself — often within roughly 1–2 years at three-to-four sessions a week. The exact payback depends on the sauna's price, how often you use it, and what you currently pay, which the calculator works out from your own numbers.

How many watts does an infrared sauna use?

Most 1–2 person infrared saunas use about 1,400–1,800 watts and run on a standard 120V household outlet. Larger 3–4 person cabins draw roughly 2,000–2,600 watts. The heaters do not run at full power the whole session — a thermostat cycles them on and off to hold temperature — so actual energy used is lower than the peak wattage would suggest.

How this is calculated (assumptions & method)

Running cost. Energy per session = heater power (kW) × session length (hours) × a 70% duty cycle, because the heaters cycle on and off to hold temperature rather than running at full power the whole time. Cost = energy × your electricity rate. Monthly uses 4.33 weeks; yearly uses 52 weeks.

Defaults. Electricity rate defaults to $0.17/kWh (near the 2026 U.S. residential average) — set it to your actual rate for a precise figure. Model presets use representative heater wattages; your exact model's spec plate may differ, so adjust the slider if you know it.

Payback. Annual savings = your spa/gym cost per year minus the sauna's yearly running cost. Payback months = purchase price ÷ (annual savings ÷ 12). It doesn't include financing, accessories, or resale — it's a straight electricity-vs-membership comparison to give you an honest ballpark.
