Introduction to In-Home Sauna Costs
Owning an in-home sauna is no longer a luxury reserved for high-end spas and hotels. More homeowners are embracing the idea of bringing wellness into their daily lives. But before you get too excited about unwinding in your private heat sanctuary, it’s essential to understand one important factor — how much current your sauna will consume and what that means for your electricity bill.
Why More People Are Choosing In-Home Saunas
From improved circulation to muscle recovery, saunas provide numerous health benefits. They offer convenience, privacy, and long-term wellness perks — all from the comfort of your home. No more scheduling spa visits or paying per session.
Understanding the Electrical Consumption
Home saunas are powered by electricity unless you choose a wood-fired option (rare for indoor use). The amount of current they draw depends on their size, type, and frequency of use.
Factors Affecting the Current Usage of Home Saunas
Type of Sauna (Infrared vs. Traditional)
- Infrared saunas heat your body directly using infrared lamps and generally consume less energy.
- Traditional electric saunas heat the air inside the room, which requires more power.
Size and Capacity of the Sauna
A two-person sauna will obviously use less electricity than a large six-person model because smaller units heat up faster and require less current to maintain temperature.
Frequency and Duration of Use
Daily 30-minute sessions will cost more over time than using it just twice a week.
Insulation and Energy Efficiency
Well-insulated saunas retain heat longer, meaning your heater doesn’t have to work as hard — saving electricity.
Average Power Consumption for Different Sauna Types
Infrared Sauna Energy Usage
Most home infrared saunas use 1.6–1.8 kW per hour. That’s less than many household appliances, making them cost-efficient.
Traditional Electric Sauna Energy Usage
These generally consume between 6–8 kW per hour for larger models. They require more preheating time, which adds to total consumption.
Portable Sauna Energy Usage
Compact and portable saunas often use 1–1.5 kW per hour, making them the cheapest to run.
Calculating the Cost of Running a Home Sauna
Understanding kWh and Your Power Bill
Electric companies charge per kilowatt-hour (kWh). To calculate costs:
pgsqlCopyEditPower (kW) × Time (hours) × Electricity Rate = Cost
Example Cost Calculations for Common Sauna Models
- Infrared Sauna: 1.7 kW × 1 hr × $0.15/kWh = $0.26 per session
- Traditional Sauna: 7 kW × 1 hr × $0.15/kWh = $1.05 per session
Monthly and Yearly Cost Estimates
If you use an infrared sauna 4 times a week:
- $0.26 × 16 sessions/month ≈ $4.16/month
If you use a traditional sauna 4 times a week: - $1.05 × 16 sessions/month ≈ $16.80/month
Ways to Reduce Sauna Electricity Costs
Proper Insulation and Placement
Place your sauna in an area free from drafts to keep heat in.
Limiting Preheat Time
Only preheat for the manufacturer’s recommended duration — no need to waste extra power.
Using Energy-Efficient Sauna Heaters
Modern heaters with built-in timers and thermostats prevent unnecessary energy use.
Maintenance for Optimal Performance
Clean heating elements and ensure vents are unobstructed for better efficiency.
Comparing Sauna Energy Costs to Other Appliances
Sauna vs. Hot Tub
Hot tubs often use 1.5–6 kW continuously to maintain heat, potentially costing more than a sauna.
Sauna vs. Air Conditioner
A central AC system can consume 3–5 kW per hour, so larger saunas may use similar or slightly more power during operation.
Sauna vs. Electric Oven
Ovens use 2–5 kW when heating — about the same as a small to medium sauna session.
Benefits of Using a Sauna Despite the Cost
Health Benefits Sauna Sessions Offer
Saunas can improve blood flow, reduce inflammation, and aid in muscle recovery.
Mental and Stress Relief Advantages
A quiet, heated environment can lower stress levels and promote relaxation.
Long-Term Wellness Investment
Like exercise equipment, an in-home sauna is an investment in your health and lifestyle.
Common Myths About Sauna Energy Usage
“Saunas Consume Too Much Power”
In reality, many saunas cost less to run than a coffee habit.
“Infrared Saunas Are Always Cheaper to Run”
While often more efficient, a large infrared sauna can still consume significant power if used heavily.
Conclusion
The current cost of running an in-home sauna depends on its type, size, and frequency of use. Infrared saunas tend to be more energy-efficient, while traditional saunas provide a classic experience at a slightly higher cost. With good insulation, modern heaters, and mindful usage, you can enjoy all the benefits sauna sessions provide without draining your wallet.
