Can You Put an Infrared Sauna Outside?

Yes, you can put an infrared sauna outside, but only if it is built for it. A model engineered for outdoor use has treated cedar, sealed and pitched roofing, weather-rated wiring, and a fitted cover. An indoor cabin moved outdoors usually fails within a few years from moisture, UV damage, and electrical problems.

The short answer

An infrared sauna can live outdoors when it is a purpose-built outdoor model. These units use exterior-grade wood such as treated cedar, sealed roofing pitched to shed rain and snow, weather-resistant seals, and electronics rated for temperature swings and humidity. Most run on a dedicated 240-volt circuit, so plan for a licensed electrician and a level, drained foundation such as a concrete pad or composite deck. Add a fitted cover to block UV and standing water between sessions. Placed and wired correctly, an outdoor infrared sauna works year round, even in cold climates, because its walls are insulated and its heaters warm your body directly rather than heating the air. What does not work is moving an indoor cabin onto a patio: indoor units are not sealed against weather, and outdoor exposure voids most warranties and creates shock hazards. If you want a backyard setup, start with a unit labeled for outdoor use. You can browse our outdoor infrared saunas to see the difference.

What makes an outdoor infrared sauna different from an indoor one?

Outdoor models are engineered as weatherproof enclosures, not just heated boxes. The main differences are:

• Exterior-grade wood. Treated cedar and reinforced panels resist rot, warping, and insects far better than the thinner interior-grade wood used on indoor cabins.
• Sealed, pitched roofing. A proper roof has an overhang and slope so water runs off instead of pooling. A common minimum pitch is about a quarter inch of drop per foot.
• Weather seals and hardware. Gaskets around doors and glass, plus stainless or coated fasteners, keep moisture out and prevent corrosion.
• Rated electronics and a cover. Control panels and heaters are built for outdoor temperature swings, and a fitted cover shields the cabin from sun and rain between uses.

If you are weighing an outdoor build against an indoor room, our outdoor sauna buying guide walks through both paths.

Do you need special wiring or a foundation?

Usually, yes. Many outdoor infrared saunas draw enough power to need a dedicated 240-volt circuit rather than a standard 120-volt household outlet, and running that line safely outdoors is a job for a licensed electrician. Confirm the exact requirement on the model you choose, since smaller one and two person units sometimes run on 120 volts. The cabin also needs a stable, level base that drains well, such as a concrete pad, pavers, or a solid composite deck, so the frame stays square and water never sits under the floor.

Can you use an outdoor infrared sauna in winter?

Yes. Because infrared heaters warm your body directly and the walls are insulated, a weatherproofed outdoor sauna performs in all seasons. In very cold weather it simply takes longer to preheat, so allow extra warm-up time and keep the cover on between sessions to hold heat and block snow. If you live in a hard-freeze region, our guide to insulating an outdoor sauna for winter covers the details.

How long will it last, and how do you protect it?

A quality outdoor infrared sauna that is properly installed and maintained can last well over a decade. Protect that investment with a few habits: keep the fitted cover on when the sauna is idle, wipe down benches and reseal exterior wood on the schedule the maker recommends, clear snow off the roof, and check door seals each season. Buying from an authorized retailer matters here, because it keeps the manufacturer warranty valid. Learn why that matters on our authorized retailer page.

Frequently asked questions

Can I just put my indoor infrared sauna on a covered porch? A fully covered, dry, wind-protected porch is lower risk than open exposure, but indoor cabins still are not sealed against humidity and temperature swings, and outdoor placement can void the warranty. Check the manufacturer terms before you move it.

Does an outdoor infrared sauna cost more than an indoor one? Usually yes, because of the exterior wood, roofing, seals, and heavier construction. The upside is a backyard unit that frees up indoor space and holds up to the elements.

Do I need a permit? It depends on your city and whether you add a foundation or new electrical service. Many plug-in units need no permit, but new 240-volt circuits and permanent structures often do. Confirm with your local building department.
