1 Person Infrared Saunas

Who a 1 Person Infrared Sauna Is Actually For

A 1 person infrared sauna is the right pick when floor space is the constraint, not budget. The footprint sits around 36–42 inches square, small enough to slot into a closet, a bedroom corner, a home gym alcove, or even a finished basement nook with low headroom. If you're in a condo, a rental, or a house where the only spare square footage is a 4×4 patch in a guest room, this is the size that fits.

The other reason people buy 1-person is solo use. You're not sharing sessions. You don't want to heat a larger cabin every day for one body. Smaller cabin volume means faster warm-up (typically 10–20 minutes from cold), less draw on the circuit, and a more focused radiant field at skin level. The downside is honest: there's no lying down. You sit upright, and most adults under 6'2" are comfortable doing that for a 30–45 minute session.

If you want the ability to recline or share the cabin occasionally, the SunRay Sedona HL100K is rated for one or two people. It's a 1–2 person hybrid footprint that gives you a bit of flex without jumping to a full 2-person indoor sauna.

FAR vs Full-Spectrum in a 1-Person Cabin

This is the decision that stalls most first-time buyers, and it matters more in a small cabin than a large one because every emitter is right next to you.

FAR infrared uses the longest wavelength in the infrared range and penetrates deepest into soft tissue. It's the wavelength behind most of the published sauna research on cardiovascular conditioning and sweat response. The Sedona HL100K and SunRay's broader indoor lineup use FAR emitters at ultra-low EMF ratings — a solid starting point if you're new to infrared and want the most-studied wavelength without the full-spectrum premium. Browse all FAR infrared models to see how they compare across sizes.

Full-spectrum combines near, mid, and far infrared in one cabin, usually with a dedicated full-spectrum emitter alongside the FAR panels. Near infrared (NIR) is where the skin-level and mitochondrial research lives, and full-spectrum models often add red light therapy in the same enclosure. The Finnmark FD-1 is our pick here. It's a 1-person cabin with full-spectrum emitters, built-in red light, and Thermo-Aspen interior that stays cool against skin. If you're already reading studies about NIR-specific effects, this is the model you want. Compare against the rest of our full-spectrum infrared cabins.

EMF and Why It Matters More in a Small Cabin

In a 1-person cabin, you're 12–18 inches from every heater. That proximity is exactly why EMF ratings matter. A heater that tests at low or ultra-low milligauss at skin distance gives you the radiant heat without the electromagnetic exposure that cheaper grey-market saunas don't disclose at all.

SunRay's Sedona tests at ultra-low EMF. The Finnmark FD-1 tests at low EMF across the full-spectrum array. Both manufacturers publish gauss readings measured at the heater surface, not somewhere across the room where the number looks better on a spec sheet. If a listing on another site won't tell you the measurement distance, that's a flag. Our full low-EMF infrared sauna collection only includes models that publish skin-distance readings.

Power and Installation: Plug It In and Go

This is the single biggest practical advantage of a 1-person infrared cabin over almost any other home sauna. Both 1-person models we carry run on a standard 120V household outlet, typically a dedicated 15- or 20-amp circuit. No 240V hardwiring, no electrician, no subpanel work. You assemble the cabin, plug it in, and run the initial burn-in the same afternoon.

Compare that to a 1-person indoor traditional sauna built around an electric heater. Even a small one needs a dedicated 240V circuit, which usually means $450–$900 in electrician labor before you can heat it up. For the full breakdown of what each heater type needs at the panel, read our guide to home sauna electrical requirements.

The 1-person cabin also draws less power per session. Most pull around 1.5–1.8 kW at peak, closer to a hair dryer than a clothes dryer. Over a year of daily sessions, that's a meaningful difference on the electric bill.

Brands We Carry in This Size

Two brands, both vetted for build quality and EMF transparency.

Finnmark Designs. Full-spectrum specialists. The FD-1 pairs full-spectrum emitters with built-in red light therapy, Thermo-Aspen interior, and Bluetooth audio in a 38" × 38" footprint. The interior wood is thermally modified to stay cool against bare skin and resist splintering, which matters more than it sounds when you're touching every wall in a small cabin.

SunRay Saunas. Accessible-priced FAR infrared with ultra-low EMF ratings across the indoor line. The Sedona HL100K is the workhorse 1–2 person model in red cedar, same chassis design as the rest of the SunRay indoor range, sized down for compact rooms. Cedar is naturally rot-resistant and gives the cabin that classic sauna scent if that's part of what you're after.

What's in the Box and What You'll Need

Both 1-person models ship as flat-pack kits. Wall panels arrive pre-wired with the heaters, controllers, and lights already installed. Assembly is mostly snapping panels together with buckle latches or tongue-and-groove joinery and connecting a few labeled plugs. Two people can complete a 1-person build in 30 minutes to 2 hours.

You'll need a level interior floor surface (carpet is fine; the cabinet sits on it like a wardrobe), a standard grounded outlet within reach, and roughly 6 inches of clearance on each side for airflow. No drain, no vent, no plumbing. The only tools are a screwdriver, and sometimes not even that.
