Plan & calculate

Plan your sauna.

Estimate the heater size and electricity bill before you build. Our calculators show their formulas, assumptions and sources so you can check the result.

Sauna running-cost calculator ↗Estimate cost per session, month and year. Choose a US state electricity reference or enter your own rate, with warm-up time and thermostat cycling.Sauna heater size calculator ↗Convert room dimensions and exposed glass or stone into an adjusted sizing volume. Works in feet or metres, with the method explained.

Keeping it simple? Open the session timer for heat, cool-down and rest. Time settings are organizational aids, not a personalized heat-exposure recommendation.
