Infrared sauna buyers guide
A home infrared sauna is a multi-year purchase. This guide helps you choose a format first, then filter brands by power, space, and warranty — before you click “Check price.”
1. Pick a format
| Format | Feel | Space | Typical budget* | Examples |
|---|---|---|---|---|
| Wood cabin | Seated room, spa-like | Dedicated floor space; heavy | Mid $$$$+ | Medical Saunas, Sunlighten, HigherDOSE cabin |
| Portable tent / panel | Enclosed NIR + heat | Corner of a room; can pack down | $$$$–$$$$$ | SaunaSpace FireLight |
| Personal foldable cabin | Sit-in pop-up | Closet when folded | $$–$$$ | Therasage Thera360 Plus |
| Sauna blanket | Wrapped far-IR heat | Minimal | $–$$ | HigherDOSE blanket |
*Relative only. See blanket vs cabin and infrared vs traditional.
2. Match electrical reality
- Standard 120V / 15A: Many blankets, Thera360-class units (~900W), SaunaSpace Classic (~1000W), smaller Medical Saunas models (e.g. Medical 3/4 at 1500–1700W on 120V/15A per brand table).
- Higher amp or dual plugs: Mid-size cabins (Medical 5/6 list higher amp needs).
- 220/240V dedicated: Large cabins (Medical 7 Plus 220V/30A; many multi-person spa cabins).
If you’re renting or can’t add a circuit, stay in the portable / standard-outlet lane.
3. Heater language without the hype
- Far infrared (FIR): Longer wavelengths; common in blankets and carbon panel cabins. Emphasis on deep-feeling heat and sweat.
- Full spectrum: Marketing umbrella for near + mid + far. Ask which emitters do what (carbon, ceramic, LED, incandescent).
- Near infrared (NIR) / incandescent: SaunaSpace-style bulbs emphasize light + radiant heat at gentler air temps (brand cites ~100–120°F ambient).
- Red light add-ons: Separate LED panels (e.g. Therasage Tri-Lite 600–980 nm) layered onto heat products.
For wavelength basics, see how red light works.
4. EMF & materials
Low-EMF is a common selling point. Prefer:
- Published measurement ranges and test distance/method when available
- Grounding / shielding you can identify as a real part (e.g. SaunaSpace guards + optional SilverLining® fabric)
- Low-VOC woods or certified textiles if you’re scent-sensitive
If a page only says “zero EMF” with no context, treat it as marketing until you verify.
5. Warranty, returns, shipping
- Blankets: often ~1 year (HigherDOSE lists one-year limited).
- Personal portables: Therasage lists 2-year manufacturer warranty + 30-day trial language on product pages.
- SaunaSpace: 5-year warranty and 100-day home trial on FireLight pages.
- Medical Saunas: 3-year warranty stated across product pages.
- Sunlighten: model-specific; check guides & specs for heaters vs fabric vs controls.
Freight, white-glove delivery, and stair carries can add cost on wood cabins — ask before you buy.
6. Who it’s for / not for
Often a good fit
- You want consistent at-home heat for relaxation or post-workout recovery
- You can dedicate space and hydrate well during sessions
- You’ve cleared heat use with a clinician if you have medical questions
Pause & ask a clinician
- Pregnancy, cardiovascular conditions, heat intolerance
- Medications that impair sweating or blood pressure regulation
- Any situation where your doctor advises against heat stress
