Features
Wood
100% non-resinous Canadian hemlock. No glues, plywood or stains.
Red light and near infrared
42.5 in by 12.5 in panel, high irradiance at 131 mW/cm² at 18 inches. Five wavelengths: 630, 660, 810, 830 and 850 nm.
Grounding port
An extra port by the floor so you can use your grounding products while in the sauna.
Bluetooth speakers
Wooden covers instead of the standard plastic, to mitigate any VOC concerns.
Warranty
10 years for wood and carpentry, 6 years for electrical components including heaters.
Industry low EMF, ELF and RF
Grounded heaters, Faraday shielding, no RF. EMF below 2 mG and ELF below 7 V/m, independently verified by Primary Environmental.
8mm tempered glass
Strong heat retention with an open, modern design.
Chromotherapy lighting
Nine settings, glass covered rather than plastic.
Panel is removable
Take the red light panel out, drop in the included glass panel, and use the light outside the cabin while the sauna stays fully functional.
Session protocol
Your red light panel, by goal.
Ideal distance is 12 to 36 inches. Standing too close converts the extra energy to heat rather than benefit. Effective dose depends on the panel's irradiance and your distance from it, and more is not better.
Dimensions
Exterior 47.2 in W by 41.3 in D by 75 in H. Interior 43 by 37.7 by 71. Red light panel 12.5 in W by 42.5 in H. Weight 340 lbs. Two inch gap recommended between the cabin and any wall or ceiling.
Electrical
Typically installed without needing an electrician.
Sauna: 120V, 1700W, dedicated 15A circuit recommended, standard US three-prong plug.
Red light panel: 120V, 400W, any standard 10A or 15A outlet, plugs in separately.
Running both at once requires a 20A circuit. Confirm this on a call before you order.
Two Inputs Leave First. This Replaces Both.
Heat makes your heart work like light exercise: heart rate climbs, blood vessels widen, blood-plasma volume expands. Red and near-infrared light does something different. It is absorbed by mitochondria, the cell's power plants, and helps them make more energy. Two separate mechanisms with two separate bodies of research, in one session, instead of a stack of equipment and a schedule to match.
01
Best Red Light Sauna For Sleep
Falling asleep is triggered by a natural drop in core body temperature, and daily light exposure sets when that drop happens. Both change in the same week outdoor life ends. Heating up, then cooling afterward, exaggerates the drop, which may help you fall asleep faster and spend more time in deep sleep. A session also acutely raises growth hormone. Many people find this is the first change they notice.

Clinical studies reviewed across sauna health outcomes3
1. Laukkanen et al., JAMA Internal Medicine, 2015. Frequent sauna bathing was associated with reduced sudden cardiac death, cardiovascular mortality and all-cause mortality in a 20-year Finnish cohort. 2. Laukkanen et al., Age and Ageing, 2017. Frequent sauna bathing was associated with lower dementia and Alzheimer's disease risk. 3. Hussain and Cohen, Evidence-Based Complementary and Alternative Medicine, 2018. Systematic review of 40 clinical studies on sauna bathing.
These are observational associations from studies of traditional Finnish sauna bathing at higher air temperatures, four to seven times a week. They describe sauna bathing as a practice, not this product, and they do not establish that a sauna causes these outcomes. Individual results may vary.

The Materials Make The Difference
Heavenly Heat Saunas Are The Gold Standard For Clean, Thoughtful Construction
Six indoor months is exactly when a cabin that off-gasses works against you. Many saunas release formaldehyde and VOCs when heated, hardest in the months you cannot ventilate. That is why this company exists in the form it does: since 1988, built for people so chemically sensitive they could not tolerate an ordinary sauna.
Durable, clean construction
Natural woods, no glues or adhesives, minimal synthetic materials, built for sensitive users.
Grounded heaters and Faraday shielding designed to minimise electric and magnetic field exposure.
Independently tested and verified for ultra-low emissions by Primary Environmental.
Precision heating technology backed by 35+ years of American craftsmanship.

Common Questions
2 Person Red Light Therapy Infrared Sauna FAQs

Can I use red light, near infrared and far infrared at the same time?
Yes. This model uses the same far infrared heater layout as our 2 Person Far Infrared Sauna, with the red light and near infrared panel added on the front wall. On the panel you can run red light, near infrared or both, with the far infrared heaters on or off. You can also remove the panel, drop in the included glass panel, and use the light outside the cabin while the sauna stays fully functional.
What is red light therapy used for?
Red and near-infrared light have been shown to support skin texture, firmness and collagen density, and may support muscle recovery and ease exercise-related soreness. It is commonly used around training and as part of a skin routine. Individual results vary
How often should I use the panel?
Three to seven times a week, 10 to 30 minutes per session, depending on your goal. The table in the Features section above breaks this down by goal.
How far should I stand from the panel?
12 to 36 inches. Standing closer does not increase the benefit: the extra energy converts to heat rather than doing anything useful, and it puts you nearer the panel's field.
Is red light therapy safe?
It is considered safe when used as directed. It is non-invasive and emits no UV. Do not look directly at the light, and use eye protection if you find it uncomfortable.
What is near infrared, and how is it different from red light?
Depth. Red light acts at the skin's surface and shallow tissue. Near infrared penetrates further toward muscle and joint tissue and stimulates cellular energy production. Our near infrared wavelengths are 810, 830 and 850 nm.
Do I need an electrician?
Usually not. The sauna runs on a standard US three-prong outlet with a dedicated 15A circuit recommended, and the panel plugs in separately to any standard outlet. Running both on the same circuit at once requires 20A. Confirm on a call before you order
What are the EMF levels, and who tested them?
EMF below 2 mG and ELF below 7 V/m, with grounded heaters, Faraday shielding and no RF. Independently tested and verified by Primary Environmental. We do not use the phrase "EMF-free," because it is not a testable statement.
