Lower-cost ways to sweat

Running costs are only part of the picture. A sauna blanket draws far less power than a full cabin — here are the budget-friendly picks plus our top traditional sauna.

Where the watts actually go

For traditional saunas, the heat-up phase is most of the bill — a 6.5 kW heater running 30–40 minutes before you step in costs more than the session itself. Infrared cabins heat up in ~10 minutes and blankets skip warm-up entirely, which is why their per-session costs are pocket change. Running cost is a tiebreaker, though, not the decision: the real choice is heat style, and purchase price dwarfs electricity for years.

Frequently asked questions

How much electricity does a sauna use?

An infrared cabin draws 1.6–3.0 kW; a traditional electric heater draws 4.5–9 kW. A 30-minute infrared session uses roughly 1–1.5 kWh (about 15–25¢ at average US rates). A 45-minute traditional session including heat-up runs 6–9 kWh (about $1.00–1.50).

Does a sauna raise your electric bill a lot?

Less than most people fear. Even a daily 30-minute infrared habit adds roughly $5–10/month at average US rates. A frequently used traditional sauna adds $20–40/month — the heat-up phase, not the session itself, is most of the draw.

Are sauna blankets cheaper to run than cabins?

Yes — blankets draw around 0.5–0.7 kW, roughly a third of a small infrared cabin, and need no heat-up time. A session costs a few cents.
