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 incandescent 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.

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.
Recently I added the trio panel to my existing Firelight sauna. Now it is very hot inside. I rotate more often. I’m very glad I have options to “turn down” the heat by leaving off a single or double light row. And I can choose at which level I need to customize the heat/light. In this day the Firelight sauna is an essential tool to detox heavy metals, nanotechnology and microplastics from our bodies. Thank you for your product.☺️
I've been using this sauna panel for a few weeks now, and it has improved my health. I really like it. Thank you.❤️
Sauna space has literally changed so much for me and my family. For myself and husband, we use in the mornings while getting ready. I use after sauna to spot treat my liver and for detox and for red light when taking an Epsom salt bath. My middle daughter uses it after every pitching lesson/practice to reduce inflammation and soreness. It noticeably helps her and I find her doing it herself. We treat spots on my youngest for her Morphea scar-like spots.
I gave my glow to a friend to use after surgery and could tell I didn’t have it for almost two weeks! My kids were asking for it !
I also use it for my dogs overall health! Thank you saunaspace for elevating our overall health and wellbeing !
Curious about how to get the most from your Hearth? You’re in the right place. From full-spectrum therapy to cabinet sauna conversions, this radiant panel opens up a world of possibilities. Below, we explore the most common questions—answered with care and depth—so you can understand not just how to use the Hearth, but how to truly live with it.
The Hearth Pedestal isn’t included, but it’s a thoughtfully designed companion piece, especially if you’re using your infrared sauna panel outside a traditional enclosure or converting an existing cabinet sauna. The Pedestal creates stable, centered support and optimizes your exposure to FireLight® therapy. You can easily add one on the Hearth Buy Page.
Yes, it's one of the best ways to upgrade a traditional or far-infrared cabinet sauna into a full-spectrum, near infrared sanctuary.
Recommended configuration: Use the Hearth Pedestal and Sauna Stool to position your Hearth at core level. Remove your built-in bench if needed, and sit comfortably on the stool to receive direct, targeted light.
Bench method: Place your Hearth on your sauna’s built-in bench. Just make sure the height and angle allow for full-body coverage.
Wall-mount option: Use the built-in handle to hang the Hearth on a wall. Be sure to anchor securely with hardware rated for at least 25 lbs.
Need more support? We’ve created a detailed guide on cabinet sauna conversions.
Yes, beautifully so. Many of our customers use the Hearth as a red light therapy panel outside a sauna for everyday wellness: while journaling, meditating, stretching, or simply resting.
You can also use it in the morning or evening as a gentle ambient light to support circadian rhythms, no flicker, no LED glare, just a warm glow that’s deeply regulating to your system.
It’s incredibly helpful for skin rejuvenation, mood balance, circadian support, and blue light mitigation, especially during screen-heavy days. The FireLight® bulbs emit a comforting, flicker-free glow, no LED glare, no harsh edges, just pure light and gentle warmth.
Without enclosure, you won’t generate a deep detox sweat (raising core body temperature requires a sauna enclosure).
Still: for non-sweat days, travel, or stacked wellness rituals, the Hearth delivers a lot, beautifully.
The Hearth is designed to be simple and versatile, no tools, no fuss.
The Hearth Pedestal is the most stable and user-friendly setup. Just place the Hearth on the Pedestal (not a bench, it’s not meant to be sat on), center it for balance, and you’re good to go. It stands freely without needing to lean on anything.
You can also use the built-in carrying handle to hang the Hearth on a wall. If you go that route, make sure to use anchors or hardware rated to hold at least 25 pounds.
Wherever you place it, the goal is the same: direct, radiant light right where your body needs it.
Surprisingly little, especially considering what it does for your energy, skin, and cellular health.
That’s less than a cycle on your dishwasher, and way more rejuvenating.
The Hearth Trio has 3 FireLight® Bulbs and is ideal for smaller spaces, shorter sessions, or stacking with other wellness tools. The Hearth Quartet has 4 bulbs and offers stronger irradiance, deeper heat, and faster therapeutic results.
If you’re using it as your primary sauna light or want more intensity, go with the Quartet. If you want something more compact or ambient, the Trio is a great fit.
Not directly. The number of bulbs is part of the Hearth’s internal design, so if you buy the Trio, it will always have 3 bulbs. If you’re unsure, go with the Quartet, you can always use fewer bulbs during a session, but you can’t add one later.
Most people sit 18 to 30 inches away. That sweet spot delivers deep warmth without overwhelming heat.
If you’re looking for gentle stimulation, start farther back. Want stronger activation? Move closer. The goal is to feel relaxed, open, and warmly held.
You can, but you don’t have to.
If you’re using the Hearth for full-body therapy, gentle rotation helps ensure even exposure. But for targeted sessions, like on your chest, face, or back, just stay still and soak it in. Let the light do the work.
Yes—many people use it daily, even multiple times a day. Sessions can be as short as 5–15 minutes depending on your distance and intention. Whether it’s part of your morning ritual, post-work recovery, or before bed, the Hearth is built for daily use.
It gets warm, intentionally. The Hearth delivers both near infrared light and gentle radiant heat, just like the FireLight® Sauna. It shouldn’t feel harsh or overwhelming, but if it ever feels too intense, increase your distance or shorten your session.
Absolutely. Though more substantial than the Glow, the Hearth was made to move with you. With a built-in handle and a lightweight design, just 7 lbs for the Trio and 11.5 lbs for the Quartet, it’s easy to tuck into the backseat for road trips, retreats, or extended stays. Just allow it to cool completely before packing, and remove the bulbs for safe transport. Whether you’re setting up in a hotel, a rental, or a quiet corner of your getaway, the Hearth brings full-spectrum healing wherever you roam.
Yes, as long as it’s stable, safe, and aimed correctly. Some people lie down with the Hearth on a chair or table nearby, especially during meditation, yoga, or breathwork. Just don’t place it on a soft surface where it could overheat or tip.
The FireLight® Bulb is rated for 5,000 hours and typically lasts 5 to 10 years, depending on use. When it eventually burns out, replacing it is simple, it screws in just like a standard bulb, no tools needed.
If it burns out within five years, we’ll replace it for free under our warranty. After that, you’ll still get a special replacement price of $95.
Long-lasting, easy to replace, and always backed by us.
