Superior Performance & Safety
Ultra-Low EMF & ELF Heaters
Experience complete peace of mind with our Nano-Carbon heaters, engineered to deliver powerful infrared heat with virtually zero EMF and industry-leading ELF reduction. Our advanced EHS heater system reduces electric fields directly at the source — without relying on metal shielding, mesh barriers, or blocking materials that can interfere with infrared performance.
Since pioneering EMF-cancelling heater technology in 2010, Sun Stream has remained at the forefront of low-EMF sauna innovation, creating a cleaner, more natural infrared experience designed for those who value both performance and peace of mind.
Excellent Full-Body Heat Coverage in a 2-Person Sauna
The Ascend 2 uses oversized side-wall heaters together with dedicated floor, calf and lower-body heaters to surround both users in radiant warmth. Its concentrated heater placement directs infrared energy toward the areas of the body where it is needed, creating a more complete experience than a 2-person sauna that relies on broad, low-density wall panels alone.
With comfortable seating for two and a movable bench included, the cabin can also be opened up when one person wants more room to relax, stretch or lie down.
High Power Concentration
Over 30 watts / Cubic Foot
The Ascend 2 delivers 1,850 watts of heating power within its spacious two-person cabin, providing over 30 watts of power per cubic foot.
Combined with smaller, high-watt-density carbon heaters and oversized side heaters positioned to extend infrared coverage towards the front of the body, the Ascend 2 delivers powerful, concentrated infrared heat throughout the cabin.
High power concentration. Excellent body coverage. Powerful infrared performance.
Open Design Heater Guards & NO Cloth Covers
Sun Stream saunas are designed to maximise infrared performance without unnecessary barriers between you and the heat. Our open-design wooden heater guards use strong, widely spaced timber slats that allow infrared energy to flow freely toward the body, unlike heavily slatted designs that can reduce heat output.
Importantly, our Nano-Carbon heaters are completely free from synthetic cloth covers commonly found on many infrared sauna panels. Cloth coverings can reduce infrared efficiency, introduce unwanted synthetic materials into the sauna environment, and make proper hygiene more difficult over time.
The result is cleaner, more direct infrared heat and a more natural sauna experience.
Premium Canadian Hemlock Infrared Sauna Construction
Crafted entirely from 100% FSC-certified Canadian Hemlock, Sun Stream saunas are built without plywood, particleboard, or hidden composite materials commonly found in lower-quality saunas. Canadian Hemlock is prized for its strength, stability, resistance to warping, and hypoallergenic properties, making it an ideal timber for premium infrared sauna construction.
We also use premium USA-made Titebond water-based glues, approved for indirect food contact, helping create a cleaner and healthier sauna environment with reduced concern around unwanted off-gassing.

The truth about full spectrum saunas
Marketing Spin
Many sauna companies claim that “full spectrum” saunas offer it all — near, mid, and far infrared. But do they really? Watch the video to uncover the facts.
EMF Exposure Risks
Alarmingly, “full spectrum” emitters guarantee exposure to higher EMF levels, which can raise health concerns. Watch the video to learn more.
Safety Over Spectrum
At Sun Stream Saunas, we prioritize science over marketing spin. We’re committed to delivering the profound benefits of far infrared without the risks.

Frequently Asked Questions,
Ascend 2 Infrared Sauna
The key difference is that the Evolve 20 features a large 300-watt heater mounted to the glass door, which adds more power and 360° body coverage.
- Outdoor placement is possible if completely protected from the weather. Colder climates will affect the warm-up time, for more detailed information see our FAQ page.
- 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.
- For the assembly process there needs to be adequate space around the sauna before it’s pushed into place.
- Clearance required is 3-5cm for the sides and top of the sauna.
Sun Stream Saunas heat up to 65°C, but unlike traditional saunas, far infrared saunas work by heating your body directly—not just the air. This radiant heat penetrates deeply to trigger a powerful detoxifying sweat at lower, more comfortable temperatures. Our saunas deliver faster, more effective results thanks to high-powered carbon heaters, full 360° heat coverage, and no fabric barriers over the panels.
A pre-heat time of only 15 minutes is all that is required to bring the heaters up to their full operating temperature prior to commencing your sauna session.

For the Evolve Mini approximately $0.35 cents per hour, and for the larger saunas like the Evolve 30 only $0.50 cents per hour. These costs are based on $0.25/kWh tariff from your electricity supplier.
Choosing the Ascend 2 for Your Home
The Ascend 2 is a two person sauna for buyers who want more room than a one-person cabin without moving to a four-person model. This 2 person home sauna measures 1221 mm wide by 961 mm deep externally and plugs into a standard 10 Amp power point.
When comparing a low EMF infrared sauna, look beyond the headline capacity. The Ascend 2 combines ultra-low EMF and ELF heaters, Canadian Hemlock construction, adjustable infrared intensity, Bluetooth audio and a residential lifetime warranty.
Is the Ascend 2 the Right Infrared Sauna for Your Home?
Choose the Ascend 2 sauna if you want a two-person infrared sauna that still feels spacious when used alone. Its narrower footprint makes it easier to accommodate than a large family model, while its movable bench, concentrated heating system and included accessories give it more flexibility than a basic compact sauna.
If you would prefer 360-degree heating with a front-door heater, compare the Evolve 20. If you need seating for a larger household, explore the Ascend 4 or the complete infrared sauna range.
A Home Infrared Sauna Designed for Everyday Use
The Ascend 2 brings a full-featured infrared sauna into a footprint suited to many dedicated wellness rooms, home gyms and spare spaces. For an indoor sauna installation, choose a dedicated area with the required clearances and suitable access. It plugs into a standard 220-240 V wall outlet, so no specialised electrical connection is required beyond confirming that the intended outlet and circuit meet the published specifications.
Use the LCD control panel to set time, temperature and lighting, choose from three infrared intensity levels, or connect the sauna through a compatible smart plug for scheduled sessions. Bluetooth audio, chromotherapy lighting, supportive backrests and the movable bench are included, giving you flexibility without turning setup into a separate project.
