Sauna type
Electric Saunas
Electric heaters offer thermostatic control and convenience. Most outdoor traditional saunas use 240V heaters that require a dedicated circuit.
What to consider
Dedicated circuit
Most traditional sauna heaters require a dedicated 240V circuit — a standard outdoor outlet is not equivalent. Hire a licensed electrician.
Trenching
Distance from your panel drives trenching and wire cost. Use our installation cost calculator to plan.
Heater sizing
Heater kW should match the sauna's interior volume as specified by the manufacturer.

How we pick
This page covers traditional rock-heater saunas only; infrared cabins live on the Outdoor Infrared page. Seller-listed voltage does not establish circuit suitability: request the exact heater manual and a licensed electrician’s assessment.
