Plug-In 120V Saunas: Which Ones Can Skip the Electrician?

By James Mancebo, South Lake Tahoe, CA · Updated 2026-11-13

Short answer: if “plug-in” means any outlet you already have, our directory has exactly one: the Clearlight Premier IS-2 (14.5A, “plugs into a standard household outlet”). Every other 120V sauna we list needs a 20-amp outlet, usually on a dedicated circuit. If you don’t already have one at the spot, budget for an electrician. Traditional (rock-heater) saunas don’t run on 120V at all.

We read the electrical spec on each brand’s or retailer’s product page. Prices for Almost Heaven, Sun Home and Plunge were checked November 13, 2026, and Clearlight prices on November 12, 2026.

Why 20 amps keeps coming up

Watts ÷ volts = amps. The Premier IS-2’s 1,750 W at 120V works out to about 14.6A, right at the limit of a 15A household circuit, which is why it can use a standard outlet. The Sanctuary 2’s 2,250 W works out to about 18.75A, so it needs a 20A circuit. Bigger infrared cabins need even more. Sun Home says its 1- to 3-person models “each take a dedicated 120V, 20A circuit; the 4-person requires 240V.”

A dedicated circuit means nothing else shares the breaker. Even with the Premier IS-2, a space heater or vacuum on the same circuit can trip it. Have an electrician check what else is on that breaker before you buy.

“Plug-in” traditional saunas are 240V

If you want a hot-rocks sauna without hard-wiring, the only plug-in traditional model we list is the Plunge Sauna Mini ($12,490). It uses a dedicated 240V/20A circuit with a NEMA L14-20 locking outlet, so you’d still need an electrician to add that outlet. Every other traditional heater we checked is hard-wired.

Snow-country notes

• None of the 120V models is sold for outdoor use. If you’re thinking about an unheated garage, check the brand’s manual for temperature and humidity limits first. We didn’t find a published garage rating on these pages. For how infrared and traditional compare in small rooms, see infrared vs traditional for small spaces.
• Outdoor plug-ins are 240V. Sun Home Luminar (dedicated 240V 20A GFCI, NEMA L6-20) and Clearlight Sanctuary Outdoor 2 (240V outlet, 2,480 W).
• Adding a 20A outlet is usually one of the cheaper electrical jobs. For published cost ranges and Reno and South Lake Tahoe permit fees, see our electrical install cost guide.

FAQ

Is there a sauna that plugs into a regular wall outlet?

In our directory, one: the Clearlight Premier IS-2 far infrared sauna. Its retailer page says it 'plugs into a standard household outlet' and draws 14.5 amps (1,750 watts). Every other 120V sauna we list calls for a 20A outlet, and most say the circuit must be dedicated.

Can I plug a sauna into a 15 amp outlet?

Not if it ships with a NEMA 5-20 plug. Sun Home's Solstice and Plunge's Infrared Sauna list NEMA 5-20, and Clearlight's Sanctuary 2 lists a NEMA 5-20P plug. That plug is made for 20A receptacles. If you don't have a 20A outlet where the sauna will go, you'll need an electrician.

Are there plug-in outdoor saunas?

Not on 120V in our directory. The outdoor plug-in models we list run on 240V: Sun Home's Luminar needs a dedicated 240V 20A GFCI circuit with a NEMA L6-20 outlet, Clearlight's Sanctuary Outdoor 2 lists a 240V outlet, and Plunge's Sauna Mini (traditional) uses a 240V/20A NEMA L14-20 outlet.
