How Many Amps Does a Home Sauna Use?
Home Sauna draws about 25 amps at 240 volts (6,000 watts running). Home Sauna runs on its own dedicated 240 V circuit — plan on a 35-40 A breaker with 8 AWG copper.
Amps = watts ÷ volts. Enter the wattage from your appliance's nameplate or label for an exact figure.

This appliance's circuit is sized from its nameplate per the NEC, not from wattage — see the circuit guidance below.
Home Sauna amperage at 120 V and 240 V
Same 6,000 W load — the current halves when the voltage doubles. Home Sauna is typically a 240 V appliance in US homes.
| Draw | Watts | Amps at 120 V | Amps at 240 V |
|---|---|---|---|
| Running | 6,000 W | 50 A | 25 A |
Breaker and circuit for a home sauna
Home Sauna runs on its own dedicated 240 V circuit — plan on a 35-40 A breaker with 8 AWG copper. A sauna heater runs flat-out for the whole session, so the 25 A draw sizes at 125% as a continuous load — most 6 kW heaters spec a 40 A circuit.
Guidance only — actual circuit sizing depends on your unit's nameplate, wire run length, and local code. Confirm with a licensed electrician. See the wire & breaker size chart for the full NEC ampacity table.
