How much does it cost to use a sauna for 10 years? Break down the details of electricity bills, maintenance, and repair costs.

On cold weekend days, soaking in your own sauna while enjoying hot drinks and looking out at the snow scenery – this is probably the kind of family leisure scene that many people yearn for. But before making the purchase, you must have secretly calculated something: buying a sauna is a one-time investment, but over the course of 10 years, how much will the electricity bills, maintenance, and repair costs add up to? Don’t worry, today we will break down this bill clearly and use real data to tell you whether owning a sauna is worth it.
First, understand the core premise: the type of sauna determines the base cost.
Before calculating the money, you need to be clear about one thing: different types of saunas have vastly different subsequent expenses. Currently, the most common types in families are traditional electric heating saunas (such as Finnish style) and far-infrared saunas. Let’s take the most mainstream 3-4 person family model as an example, calculating based on a frequency of 2-3 uses per week, each lasting 1 hour – this is also the average usage habit of families in Europe and America.
Also, it should be noted that the electricity cost is calculated based on the average level of major countries in Europe and America: approximately $0.15 per kilowatt-hour in the United States and $0.3 per kilowatt-hour in most European countries. We will provide detailed breakdowns by region to help you match it up.

The first bill: Electricity – Cheaper than you think
Many people worry that “once the sauna is on, the electricity bill will skyrocket”, but the actual data will overturn your perception. The key lies in the power consumption and usage habits of the sauna. Let’s calculate clearly for the two mainstream types:
1. Traditional electric heating sauna (6-kilowatt heater)
The traditional model needs to preheat for 15-20 minutes to reach the ideal temperature (about 80-100°C), plus the usage time, the actual electricity consumption is approximately 1.25 hours. Calculated based on a power of 6 kilowatts, the electricity consumption per time is 6 kW × 1.25 h = 7.5 kWh.
– United States region: Each time the electricity bill is 7.5 × 0.15 = $1.125; 3 times a week is $3.375, approximately $175.5 for a year, and the total cost over 10 years is approximately $1755.
– European region: Each time the electricity bill is 7.5 × 0.3 = $2.25; 3 times a week is $6.75, approximately $351 for a year, and the total cost over 10 years is approximately $3510.
Tip: If you only use it 2 times a week, the electricity cost can be saved by one-third, in the United States it is as low as $1170, which is actually similar to subscribing to an additional streaming service membership!
2. Far-infrared sauna (2-kilowatt heater)
The advantage of the far-infrared model is that it heats up quickly, within 10 minutes, and the temperature is lower (40-60°C), with a total usage time of approximately 50 minutes, and the electricity consumption is only 2 kW × 0.83 h ≈ 1.66 kWh.
– United States region: Each time the electricity bill is 1.66 × 0.15 ≈ $0.25; 3 times a week is $0.75, approximately $39 for a year, and the total cost over 10 years is approximately $390.
– European region: Each time the electricity bill is 1.66 × 0.3 ≈ $0.5; 3 times a week is $1.5, approximately $78 for a year, and the total cost over 10 years is approximately $780.
Key point: The electricity cost of the far-infrared sauna is almost 1/5 of that of the traditional model, if your budget is limited, choosing it is definitely the right choice. And many users have reported that the electricity bill is almost unchanged when using the far-infrared model.
The second bill: Maintenance fee – Low cost to extend lifespan
The core of sauna maintenance is wood care and cleaning. As long as these two points are done well, it will be completely fine to use for 10 years, and the cost is much lower than maintaining a car.

1. Daily cleaning: Under $50 to handle
The sauna interior cannot use harsh cleaners (high temperatures will cause chemical substances to evaporate), the most cost-effective method is to use white vinegar + warm water for wiping, then dry with a dry towel – these materials are usually available at home, with zero additional costs. If you want a hassle-free experience, buy a professional sauna cleaner (about $60), which can be used for 1-2 years. Over 10 years, the cleaning cost will be around $300-$600.
Additionally, the towels and cushions in the sauna should be cleaned weekly. This cost can be included in the household laundry expenses and is almost negligible.
2. Regular maintenance: Once every 2-3 years, $200-$800 for 10 years.
This mainly involves the care of the wooden sauna panels to prevent cracking and deformation. One gallon of professional wood oil is about $160 and can be applied 3-4 times, sufficient for 6-8 years; a set of sealant (about $60) is also needed, and the maintenance cost over 10 years will be a total of $200-$800.
If it’s a far-infrared sauna, since the temperature is low and the humidity is low, the maintenance is simpler, and the 10-year maintenance cost can even be controlled within $200.
The third account: Maintenance costs – Preventing problems can save half
The failure rate of saunas is actually very low, especially for household models (commercial models have a higher failure rate due to frequent use). The possible maintenance problems encountered in 10 years are as follows, with detailed cost breakdowns:
Failure type
Repair/Replacement cost
10-year occurrence probability
Heater failure (most common)
$200-$800 (including labor)
About 50% (heater lifespan for household models is usually 5-20 years)
Door panel deformation/carding
$100-$500
About 30% (higher probability in humid areas)
Electrical circuit problems (such as short circuits)
$200-$1500 (requires certified electrician operation)
About 20% (can be avoided by regular checks)
Wooden wall panel mold/damage
$500-$2000
About 10% (preventing ventilation can prevent)
Key reminder: Spending 10 minutes each year checking the circuit and ventilating for 30 minutes after each use can reduce the failure rate by over 60%. If you choose a brand with a 5-year warranty when purchasing, the maintenance costs for core components such as heaters can be saved by half.
Overall, the 10-year maintenance cost is estimated to be between $500-$1500. With good luck, you might not have to spend a penny.
Final summary: How much is the total cost over 10 years?
Let’s add up the three costs and calculate based on the “mainstream scenario of the United States region + using 3 times per week”. The 10-year total cost for the two types of saunas is as follows:
– Traditional electric heating sauna: Electricity cost $1755 + maintenance cost $500 + repair cost $1000 = approximately $3255 (average monthly $27).

– Far-infrared sauna: Electricity cost $390 + maintenance cost $200 + repair cost $800 = approximately $1390 (average monthly $11.5).
Is this figure cheaper than you imagined? You should know that the average annual cost of using a gym sauna in an American household is $600+, and over 10 years, it’s $6000. Installing one at home is actually more cost-effective.

Finally, 3 money-saving tips for beginners:
1. Choose the right installation location: Install it in a well-insulated place like a garage or stairwell, which can reduce 20% of the electricity cost (shorter preheating time).
2. Utilize off-peak electricity: In many regions, the nighttime electricity cost is half of the daytime, and using it from 10 p.m. can save $300-$800 over 10 years.
3. DIY maintenance: Wood oil care, door panel adjustment, etc. These simple operations have many tutorials online, and doing it yourself can save 50% of the labor cost.
