The most common surprise after buying a sauna is the electrical bill — not the monthly one, the one from the electrician. Here's how to avoid it.
The two numbers that matter
- Voltage: 120V is a regular household circuit in the U.S.; 240V is what dryers and ovens use.
- Amps: the circuit's capacity (e.g. 20A, 30A). Most saunas want a dedicated circuit — nothing else on it.
Real examples
| Model | Type | Power |
|---|---|---|
| Sun Home Solstice 1–3, Equinox 2–3, Pod | Indoor infrared | 120V · 20A |
| Sun Home Eclipse 2 | Indoor infrared + red light | 120V · 30A |
| Sun Home Solstice 4, Luminar 2 | Indoor / outdoor infrared | 240V · 20A |
| Sun Home Eclipse 4, Luminar 5 | Indoor / outdoor infrared | 240V · 30A |
| Plunge All-In Gen 2 (cold plunge) | Cold plunge | 120V · 15A dedicated |

Before you order
- Look up the exact model's voltage, amps and plug type in its manual.
- Check your panel for a free slot and capacity.
- Get an electrician's quote — and ask whether your city needs a permit.
- Outdoors: plan a weatherproof power run to the sauna location.
Rule of thumbSmall indoor infrared units are the easiest to power. Traditional heaters and big or outdoor saunas usually mean 240V and an electrician.
