The single most overlooked cost of a home sauna is the wiring. Check this before you choose a model.
What each kind needs
| Sauna | Power | Notes |
|---|---|---|
| Two-person infrared (most) | 120V, 15–20A | Often a dedicated circuit |
| Dynamic Barcelona | 120V, 15A | Standard outlet |
| Sun Home Equinox 2 | 120V, 20A dedicated | Plug-in |
| Outdoor infrared (Luminar 2) | 240V, 20A GFCI | Dedicated circuit |
| Barrel with 6 kW heater (Luna) | 240V, 30A breaker, 10-gauge wire | Hard-wired |
Infrared cabins
Most run on 120V household power. Many need a dedicated circuit, meaning nothing else is plugged into it. If yours needs 20 amps and your outlet is on a 15-amp circuit, you'll need an electrician.
Barrels and traditional saunas
Electric heaters need 240V, the same as an electric dryer or range. Running a new circuit to the backyard typically costs a few hundred dollars, more for long trenches or a panel upgrade. Wood-burning heaters avoid wiring entirely.
Tips
- Get an electrician's quote before ordering.
- Ask whether your panel has space for a new breaker.
- Outdoor circuits usually need GFCI protection; follow local code.
- Many areas require a permit for new circuits.
Questions
Can I plug an infrared sauna into any outlet?
Only if the sauna's requirements match the circuit, and it's not shared with other heavy loads.
Can I use an extension cord?
No. Plug directly into a suitable outlet.
