How Much Does an Infrared Sauna Cost to Run? (Real Math)

Sticker price isn't the whole story — buyers always ask about running costs. Here's the honest infrared sauna electricity cost math.

The Formula

kW × hours × your $/kWh = cost per session. A typical 2-person home sauna draws ~1.8 kW. A 45-minute session (including preheat) uses about 1.35 kWh.

By State (at $0.17/kWh US average)

1.35 kWh × $0.17 = ~$0.23 per session. Even in high-rate states ($0.30/kWh), that's about $0.40. Daily use for a month: roughly $7–$12 added to your electric bill.

What Affects the Number

• Size: a 1-person infrared sauna uses less than a 3-person cabin
• Insulation & placement: garages in winter cost more to heat than spare bedrooms
• Session length: 20-minute sessions roughly halve the figure

The Honest Takeaway

Running a home infrared sauna costs less than a single coffee-shop latte per week. If operating cost is holding back your decision, it shouldn't — focus instead on build quality, heater design, and delivery terms. Compare models on our infrared saunas for sale page.
