Ultra Low EMF (Magnetic Fields) and Industry’s Lowest EF/ELF (Electric Fields)

Relax and enjoy your Sun Stream sauna knowing that our all new EHS heater technology reduces EMF & ELF to an all new Industry low.

Smaller Concentrated Heaters

Concentration of the electrical power into smaller hotter panels results in a superior sauna experience, raising your core temperature and inducing a faster heavier sweat.

No Cloth Covers on the Heaters

Most competing Infrared Sauna brands are adhering synthetic cloth covers to their carbon panel heaters. Our Sun Stream ‘Nano-Carbon” heaters do not use cloth covers.

Industry Leading Key Features

360° Degree Infrared Heat

Experience a superior 360° immersion in radiant heat with one of our large 300 watt heaters placed directly in front of your body, the most complete body coverage of all sauna brands, for a faster heavier sweat.

Ultra Low EMF & ELF

Since 2010 Sun Stream Saunas has been on the cutting edge of low EMF heater technology which reduces harmful EMF ‘magnetic fields’ to an average of less than 1mG. Then in the Summer of 2018 our innovative EHS heater and electrical system was further developed to reduce ELF ‘electric fields’ to all new industry low levels making Sun Stream safer than any other brand on the market.

Superior Heater Technology

Sun Streams high watt density nano carbon heater technology has a high emissivity rating due to microscopic ‘nano carbon’ particles which are very efficient at radiating far infrared heat. The health benefits derived are dependent on the amount of infrared heat projected at your body to induce a faster, heavier sweat!


In addition to our industry leading low EMF & ELF heater technology, all Sun Stream Saunas are built entirely from 100% Premium Grade Canadian Hemlock / NO Plywood or Particle board hidden in the roof or floor, and constructed using Titebond water-based Food Safe Glue.

Where can I place my sauna?

  • The Saunas can be placed on carpet, tiles, timber or concrete flooring.
  • The surface the sauna is placed on ideally needs to be perfectly level, however if slightly out, levelling will be required.
