Proprietary FireLight® Bulb
At the core of every SaunaSpace experience is the FireLight® Bulb—our signature innovation, shaped by over a decade of R&D. Hand-blown from pure quartz-stained glass, it delivers a finely tuned spectrum that peaks in red and near-infrared for maximum light therapy, while extending into mid- and far-infrared for deeply effective heat.
This full-spectrum design captures the most healing wavelengths of the sun—without the harmful ones—activating cellular repair, detoxification, and full-body rejuvenation. Built for longevity and performance, each bulb offers thousands of hours of radiant therapy and comes backed by a five-year warranty. This isn’t just a bulb. It’s the light that transforms.
Our signature innovation, the FireLight® Bulb is the result of over a decade of R&D. Hand-blown from pure quartz-stained glass, it emits a full-spectrum glow calibrated for optimal red and near-infrared light.
This biologically aligned spectrum supports deep heat, cellular repair, and rejuvenation—thousands of radiant hours, zero harmful wavelengths.
EMF-Shielded Design
Unlike most infrared saunas and red light devices—which often expose users to high levels of EMFs—the Hearth Panel is fully shielded and grounded at every connection point. Electromagnetic fields have been shown to disrupt cellular signaling and increase oxidative stress.
By eliminating this hidden interference, the Hearth Panel supports a deeper, more complete healing response—calming your nervous system while amplifying the power of FireLight®.

EMFs can disrupt cellular signaling and increase oxidative stress. By eliminating this interference, the Hearth™ supports deeper healing, calming your nervous system and amplifying the power of FireLight®.
Adjustable Intensity Levels
With three manual switches, the Hearth Panel lets you choose from low, medium, or high intensity—so you can tailor each session to your needs.
Ideal for first-time users, the highly sensitive, or anyone seeking a gentler start, this customizable control ensures you get the most out of FireLight® at your own pace.
Trio and Quartet Options
Choose the Trio for smaller spaces, cozy corners, or targeted sessions, or go with the Quartet for full-body immersion. Whether you build a complete sauna or use FireLight® throughout your home, both options deliver spectrum-tuned light and deeply restorative heat to support healing and rejuvenation.
Especially comforting during colder months, and ideal for daily rituals, moments of self-care, and deep, body-centered restoration.
Choose the Trio for smaller spaces or targeted use, or the Quartet for full-body immersion. Both deliver spectrum-tuned light and restorative heat to support healing.
Ideal for daily rituals, self-care, and deep replenishment—especially in colder months or anytime your body craves warmth, grounding, and renewal.
Sustainable Basswood
Sourced from responsibly managed American forests, basswood is a lightweight hardwood with a creamy tone, fine grain, and subtle, honeyed scent. Long used in herbal traditions for its calming properties, it brings a sense of warmth and quiet beauty to your space.
Each piece is hand-shaped and sanded to a velvety finish by skilled makers, then left completely untreated—free of stains, sealers, or synthetics—to preserve the purity of the wood and the integrity of your sanctuary. A time-honored material, reborn for modern healing.
Non-Toxic Stainless Steel
All hardware is made from uncoated, medical-grade stainless steel—free from aluminum, paints, plastics, and synthetic coatings. We use no glues, no composites, and no hidden materials. Just clean, hypoallergenic strength that won’t off-gas or break down over time. Built for purity. Designed to last.
SuperSauna (Optional Upgrade)
Transform your Hearth Quartet into a SuperSauna by adding a three-bulb Hearth™ Trio. This powerful configuration surrounds you with amplified light and heat—doubling the intensity to deliver the same benefits in half the time.
The experience is immersive and deeply satisfying, with a radiant warmth that feels as good as it is effective. More heat, more light, more of what your body craves.

SaunaSpace,
Jazmyn was super helpful to me and very professional and knowledgeable with your product.
I really was extremely impressed with her. It is rare companies have someone like this who could answer all of my questions while being extremely patient and nice.
For me personally and my body. I enjoyed the product, but for my body type, I cannot tell any difference in my health.
I somehow can notice a big difference when I workout and sweat though on a elliptical, slow jog, and weights for example.
Which causes me to sweat more and of course gets my entire body flowing and moving.
Therefore, I did not keep the product.
However, the 100 day money back guarantee is worth it for everyone to try at least.
And the product is beautiful all around...and yes, pricey for most, but with our government making the dollar with nothing soon...we might as well buy something useful and helpful like this beforehand.
😉
Perfect solution for a DYI sauna. Well constructed, easy to mount, very sturdy. Provided a great sweat from the very first session. Started to feel the results of detoxing my skin and body after just a few times using it. Have experienced better sleep, increased energy and improved skin health. Best home upgrade I’ve ever made, would recommend it for anyone who in seeking improved mental and physical health.
I created my own space in my closet with cotton drapes, tension bars, a little stool and bench, and VOILA … a perfect place for a Sauna Space panel and experience. I love going in there. It’s like food, or sunshine, delicious and luxurious!!
I bought bother the 4 bulb and the 3 bulb panel and put both in my sauna space. I have used this daily for the last 2 months and it is the real deal!!! I work out 6 days a week and I can truly feel the therapy benefits in recovery. I highly recommend!!!
I love my sauna panel. I created my own space in the bathtub using organic hemp canvas and a big rod over the tub. It is my favorite place at home and it truly heals me. I can feel it in my energy levels, my strength and at night when I soundly sleep. I wake up feeling rested and ready for a great day.
I would recommend it to anyone.
The Hearth Pedestal is an optional accessory you can add to cart on the Hearth Buy Page.
If you want to upgrade your sauna, our Hearth Infrared Sauna Panel is the best option to turn your existing far-infrared, or other cabinet-style sauna, into a full-spectrum infrared sauna!
Recommended setup: Buy the Hearth Pedestal and Sauna Stool with your Hearth to target your core. Remove your sauna’s built-in bench.
Bench setup: Set your Hearth on your sauna’s built-in bench. Sit on your own chair or our Sauna Stool.
Hanging setup: Use the carrying handle to hang your Hearth on the wall. Make sure to use proper anchoring that is rated to support at least 25 lbs.(hooks, rope, etc.)
Due to variables beyond our control, customers experience different heating when using the Hearth unique environments. The Hearth Quartet only heats an area of 60-70 cubic feet. This online calculator can be used to calculate the cubic footage of your space.
For a full explanation of how to upgrade your cabinet sauna with a Hearth, read this article in our Help Center.
Yes, absolutely, and you receive all the benefits of red light therapy. We have many customers who enjoy using our Hearth this way, as some will even do yoga and meditate in front of our lights!
You can also have it near you while you’re working on a computer or watching TV to block out blue light. Some people also like to use it as an ambient light in the evenings and mornings instead of harsh LEDs and fluorescents.
However, note that the detox will be mild without an enclosure. The most profound detox occurs when the body core temperature is increased enough to get a strong sweat response.
The Hearth Pedestal is specifically made to be used with our Hearth, and also with the Glow. It is not a bench for the user.
Set the Hearth on the Pedestal, centered for balance, and the Hearth will stand by itself.
The Hearth doesn't need to lean against anything; just set it down and center it on the Pedestal and enjoy!
The Hearth includes a built-in carrying handle that can be used to hang it from a wall. Make sure to use proper anchoring that is rated to support at least 25 lbs.(hooks, rope, etc.).
The Hearth Trio uses 750W, which costs about 12¢ per hour based on average kilowatt-hour (kWh) cost in the USA.
The Hearth Quartet uses 1000W, which costs about 16¢ per hour based on average kilowatt-hour (kWh) cost in the USA.
