Infrared sauna electricity cost
This page is the kWh and dollar line for home infrared cabins — not a review of heat quality and not a medical article. Defaults last reviewed 2026-09-09.
Inputs
Use your rating plate and bill rate. Presets are typical nameplates, not a brand recommendation.
Off: only session minutes are billed. Traditional rooms often need 20–40 minutes of heat-up.
Optional: purchase amortization
Spreads a purchase price across years or a lifetime session count. Not financing or resale.

What actually moves the bill
- Nameplate watts. A 1,200 W cabin is two-thirds the energy of 1,800 W at the same minutes.
- Clock time. Energy scales linearly with minutes, including heat-up if you include it.
- Your $/kWh. Hawaii-class rates can more than double the U.S. average example.
- How often you sit. Four sessions a week is ~17.3 sessions a month in this model (52÷12).
