The Solo System is a sliding double dome that sits over a heated pad. You lie down with your body inside and your head out. The domes use Sunlighten's SoloCarbon far-infrared heaters in five zones, up to 150°F, and the pad adds four more heaters underneath. Sunlighten says it is built from bamboo carbon material and stresses that it is not a sauna blanket: you lie under rigid domes rather than zipping into a heated wrap.
It plugs into ordinary outlets: the domes draw 1,260W (10.5A) and the pad 300W, both on standard NEMA 5-15 plugs. The domes weigh 46 lb and the pad 13 lb, so it can be packed away between sessions. The "Chromo" version on the US store includes chromotherapy lighting.

What it costs to run
The Solo System draws up to 1,560W. At the July 2026 U.S. residential average of 18.31¢/kWh (EIA), an hour at full draw costs about $0.29.
Real sessions usually cost less, because the heaters cycle once the cabin is warm, but warm-up time adds to it. Put your own rate into the running-cost calculator.
Before you order
- You need floor space about 74 in long and 28 in wide, plus room to get in and out, and two outlets (or one circuit that can carry about 1,560W in total).
- Sunlighten's instructions start beginners at 15 minutes on the low setting.
- If you want to sit up, read or share the session, a one-person cabin such as the Signature I is the alternative; on the US store it lists at 2.4 times the Solo's price and needs a dedicated 20A circuit.
Delivery, assembly, returns and warranty are the same across Sunlighten's range; they are covered in our Sunlighten review. We have not tested Sunlighten saunas and do not rate them.

- Amplify and Amplify RED: Amplify is Sunlighten's hot one: far infrared plus halogen full-spectrum heaters, up to 170°F. Amplify RED adds red and near-infrared light panels.
- mPulse: mPulse is Sunlighten's flagship: red, near, mid and far infrared controlled separately, preset programs, a built-in tablet and an app.
Frequently asked questions
Is the Sunlighten Solo a sauna blanket?
No. A sauna blanket is a soft heated wrap you zip into. The Solo is a pair of rigid domes over a heated pad, with heaters a short distance from your body. Both are lie-down, one-person, plug-in options.
How hot does the Sunlighten Solo get?
Sunlighten lists a maximum of 150°F for the domes.
Does the Solo need special wiring?
No. Both parts use standard NEMA 5-15 plugs. Together they draw about 1,560W, so avoid sharing the circuit with other large loads.
