A traditional sauna, for example, can cost around $20 per hour to run, while an infrared sauna will cost about half that. In Germany, where electricity costs around €0.38 per kWh, a standard sauna session can cost between €2.30 and €3.40.
To give you a better idea, here's a rough estimate of the monthly costs of running a sauna:
Keep in mind that these are just estimates and your actual costs may vary depending on your specific situation.
Cost of a Session
A standard sauna session can cost anywhere from €2.30 to €3.40 in Germany, where electricity costs around €0.38 per kWh.
In the United States, the same session costs between $1.00 and $1.50, with electricity averaging $0.17 per kWh.
The cost of a sauna session also depends on the size of the sauna, materials used, and heater power, which can affect the time it takes to heat up.
Using a sauna with compatible heaters, like MyHarvia 2, can help you track energy use in real-time and adjust sessions with timers or presets to keep costs manageable.
In comparison, a traditional sauna that can fit 3-5 people would use about 9-13kWh in power, making the cost per session around $5.50 daily in some regions.
This can add up to an extra $1997.28 per year if you use traditional saunas about five times a week, raising your yearly energy costs by up to 150%.
To calculate the cost of a sauna session, you can use the formula: wattage (in kilowatts) × hours used per month × cost per kilowatt-hour used = monthly cost.

Cost to Own?
Owning a sauna can be a significant investment, with prices ranging from $4,000 to $15,000 for a six-person infrared sauna.
The initial purchase and installation costs are the largest expenses of owning a sauna, but you'll also need to consider ongoing maintenance and replacement parts.
You can expect to pay $1,000 for installation, although prices can vary depending on your area and the type of sauna you buy.
Eventually, you'll need to replace parts that wear out, such as the heating element, which may fail after several years.
To give you a better idea of the costs involved, here's a rough breakdown of the expenses:
- Initial purchase: $4,000 to $15,000
- Installation: $1,000
- Ongoing maintenance: variable
- Replacement parts: variable
It's worth noting that the cost of running a sauna can also add up over time, depending on how often you use it and the price of electricity in your area.
A traditional sauna can cost at least $20 per hour to run, while an infrared sauna will cost about half that.
To calculate the monthly energy costs of your sauna, you'll need to consider the wattage, hours used per month, and the cost per kilowatt-hour charged by your electric company.
Here's a simple formula to help you estimate your monthly energy costs:
wattage (in kilowatts) × hours used per month × cost per kilowatt-hour used = monthly cost
For example, if you have a 6 kW sauna that uses 225 kWh per month, and your electricity costs $0.12 per kWh, your monthly energy costs would be:
225 kWh × $0.12/kWh = $27.00 per month
Factors Affecting Cost
The cost of running a sauna depends on several factors, including the size of the sauna, whether you choose a traditional or infrared sauna, and the type of heater your sauna uses. These factors can greatly impact the overall cost of ownership.
The price of electricity also plays a significant role in determining the cost of running a sauna. In Hawaii, for example, electricity costs an average of $0.34 per kWh, while in Idaho, it's around $0.10 per kWh. This means that even a small difference in electricity cost can add up over time.
Here are some estimated costs of running a sauna for one hour, based on different electricity prices:
By understanding these factors and making a few simple adjustments, such as minimizing the time the heater is on and lowering the sauna's temperature, you can reduce your energy consumption and control the cost of your sauna sessions.
Infrared Makes a Difference
Infrared saunas are a game-changer when it comes to cost-effectiveness. They only take 15 minutes to preheat, and an average session runs around 20-30 minutes, costing at most $0.56 per hour to use.
This translates to a monthly cost of $9.25 or $112.59 per year, which is significantly less expensive than traditional saunas. Choosing a smaller infrared sauna can further reduce costs to $0.19 per day, $5.70 per month, or $69.40 yearly.
The cost difference between infrared and traditional saunas is substantial, especially considering the added benefits of infrared heat. Traditional saunas, on the other hand, can cost upwards of $27.00 per month to operate, as seen in Example 1.
Infrared saunas are also more efficient, using less energy to produce the same heat. A 30-minute session consumes 6-8 kWh of energy, costing between $1.00 and $1.50 in the US, or between €2.30 and €3.40 in Germany.
Small things, big impact
Small things, big impact. It's amazing how making a few simple changes can make a big difference in the cost of running your sauna. For example, if you use a traditional sauna, you can expect to pay around $27 per month to run it for 75 minutes a day.

One of the easiest ways to reduce energy cost is to minimize the time the heater is on. You can do this by heading into the sauna as soon as it's hot enough, or even slightly before it. This can save you around $13 per month, based on the average cost of energy.
Another easy way to reduce energy cost is to lower the sauna's temperature a little bit. As it turns out, good steam is produced at temperatures as low as 70°C / 158°F. This can make a big impact on your energy consumption.
Here are some tips to help you make the most of your sauna sessions:
- Minimize the time the heater is on by heading into the sauna as soon as it's hot enough.
- Lower the sauna's temperature to 70°C / 158°F or lower.
- Check your sauna stones once a year and replace any eroded ones to ensure they're functioning properly.
By making these small changes, you can enjoy your sauna with peace of mind and reduce your energy costs.
Comparing Costs
A traditional sauna can be a costly investment, but how expensive is it to run one? Let's break it down.
A traditional sauna that fits 3-5 people uses about 9-13kWh of power per session. If we estimate that users sit in it for an hour and a half, including preheating, and it takes an average of 9kW per hour in power, they would spend about 18kWh to use it.
