Sun Stream Full-Spectrum Infrared Sauna
US-headquartered direct-to-consumer infrared sauna brand selling into the UK. Full-spectrum heaters, low-EMF certification.
4.0 / 5
★★★★★ ★★★★★ Highly recommended
Strengths
- Full-spectrum heater architecture combines near-IR (cellular regeneration claim), mid-IR (deep tissue claim), and far-IR (heating efficiency)
- Low-EMF certified - under 3 mG at body distance, important for buyers concerned about electromagnetic exposure
- 5-year cabin + heater warranty (comparable to UK premium tier)
Watch outs
- US-headquartered with no UK office - customer service in US time zones can be inconvenient
- 10-14 week UK lead time (ship-from-US plus customs)
- Full-spectrum benefits are contested in the infrared sauna research literature - independent studies haven't fully validated the near-IR cellular regeneration claims
- Heater type Full-spectrum infrared (near + mid + far IR combined)
- Range 1-person to 4-person cabins
- Wood Hemlock or western red cedar (cedar upgrade adds £400-600)
- EMF Low-EMF certified - under 3 mG at body distance
