TRUE 360 Degree Surround Infrared Heating

Most Infrared saunas are sadly lacking in Infrared radiant heat aimed at the front facing surfaces of your body. Discount sauna brands often have no heaters in the entire front half of the sauna.

The Evolve 20 design delivers more Infrared radiant to your body with our large carbon panel heaters surrounding you completely 360 degrees on all 4 walls plus large foot and leg heaters. 

Relax and enjoy complete immersion in the soothing Infrared heat. The Evolve 360 design ensures a great sauna experience, without cold voids in the sauna room and a FASTER, HEAVIER SWEAT !!

'Evolve EHS' Ultra-Low EMF & Near Zero ELF

Sun Stream Infrared Saunas have been on the cutting edge of low EMF Infrared heater technology since 2010.

Ten years ago Sun Stream introduced our Ultra- Low EMF carbon panel heaters which reduce EMF magnetic fields to an average of less than 1.0mG. (Many sauna brands measure 100+ mG)

In Spring of 2019 development of our latest heater innovation was completed and the ‘Evolve EHS’ heaters were incorporated into the Evolve 10 sauna. Our new EHS heaters and electrical system involves numerous innovations which reduce the ELF electric fields to near zero levels. An all new industry low !!

100% Solid, Hardwood Basswood | NO Plywood, NO Particleboard

The Evolve 20 is built entirely from premium grade hardwood Basswood

No engineered wood products such as Plywood or Particleboard are used in the construction as these are highly suspect to emit formaldehyde when heated. 100% Basswood lumber…that’s all.

Basswood is loved by carver’s and professional model builders for its uniform grain and resistance to cracking and splitting. Basswood machines very well with smooth beautiful finishes and a bright clean appearance. Historically, it has been used for utensils and food containers. Modern day it is commonly used for window blinds and guitar bodies and premium grade Infrared saunas for its stability and longevity.

All species of woods have their own distinctive aroma. Basswood has a moderate aroma, far less than Western Red Cedar, which is typically used for hot rock traditional saunas.

No Synthetic Cloth Heater Covers

Most competing Infrared Sauna brands are adhering synthetic cloth covers to their carbon panel heaters.The Mini’s ‘Evolve EHS’s heaters do not use cloth covers.

  • Introduce potentially off-gassing glues and fabrics into the sauna (chemical flame retardents)
  • Reduce Infrared heat output
  • Inhibit cleaning sweat off the heater surface (especially problematic for floor heaters)

'Titebond' Made in USA, Water Based wood glues

No mystery glues used in your new Evolve sauna!

All Sun Stream Saunas use brand name ‘Titebond’ wood glues which meet FDA criteria for ‘food contact safety’ and are used to make wooden cutting boards, salad bowls etc.

Just one more way that we strive to minimize synthetic potentially off gassing materials and ensure a healthy sauna experience.

2 Full Size Backrest Included !

The Evolve 20’s backrests are constructed from Western Red Cedar for extra sweat stain resistance and for Cedar’s unique anti-microbial properties. 

The angled design sits firmly on the bench and provides comfortable lower back support.

Neck/shoulder Height Heaters & Open Design Heater Guards

All Sun Stream Saunas feature ‘high watt density’ carbon panel heaters that come to neck/shoulder height. Heater sizing and positioning is critical to the design of an effective Infrared sauna. Most IR saunas use large, tall, narrow heaters extending above the user’s head thus wasting some of the Infrared radiant heat above your body where it is not needed.

Our shorter, smaller heaters have a greater power concentration (higher watt density), a higher surface temperature and thus produce a greater intensity of Infrared heat which is aimed at the mass of your body.

Our ‘Open Design’ heater guards, with a minimum # of wood slats, also helps to ensure maximum Infrared delivered to your body.

The 'Option-L' Movable Bench

Purchase  a 2nd movable bench to create a large platform.
