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
