Of the 140 saunas we list, 31 plug into a standard 120V outlet, 23 need a dedicated 120V circuit and 86 need a dedicated 240V or 30A circuit. The heater decides which.
A standard 120V, 15A household circuit can deliver about 1,800 W, and less is recommended for a continuous load. That's enough for many infrared cabinets. Traditional stoves usually run 4.5 to 9 kW, which needs 240V. Here's how it splits by heating type:
| Heating | Standard outlet | Dedicated 120V | 240V or 30A |
|---|---|---|---|
| Infrared | 31 | 22 | 3 |
| Traditional | 0 | 0 | 79 |
| Hybrid | 0 | 1 | 4 |
A 240V sauna needs a dedicated circuit, often hardwired, run by a licensed electrician, and sometimes a permit or panel upgrade. Our installation cost guide has sourced ranges. A plug-in sauna avoids that cost, but check that the outlet isn't shared with other heavy loads.
Main advantage: Long warranty: 10 years on the cabin indoors (5 if used outdoors), lifetime on the heaters
Main compromise: No clear weak spot against similar saunas in the published specs
Main advantage: Strong heat for its type: up to 170°F
Main compromise: Priced high for its category: $9,995 against a $4,290 median for infrared outdoor saunas
Main advantage: Low price for what you get: $1,999 against a $3,098 median for infrared indoor saunas
Main compromise: Wattage not published, so running cost can't be estimated
Main advantage: Low price for what you get: $2,099 against a $3,098 median for infrared indoor saunas

Check what your panel needs, installation cost and running cost. Still deciding on a type? Read infrared vs traditional and indoor vs outdoor, or see how the brands compare. A licensed electrician should confirm any wiring before you order.
31 of the 140 saunas we list are sold as plug-in for a standard 120V outlet, mostly infrared. An electrician should still check the circuit isn't shared with other heavy loads.
