    I love this sauna so much!

    This review is long overdue, but I just had to post because I had an incredible experience recently. I’ve been using my sauna regularly for the past 3 1/2 years, and it has helped me in so many ways — high energy levels, great mood, high-quality sleep, glowy skin, fast recovery from workouts. But the most amazing thing happened last week, I went to the functional medicine doctor for the first time in years, just to check up on everything, and they did a full panel of bloodwork, they must’ve taken like 30 vials of blood and tested for everything — from nutrition and hormones to inflammatory markers and even toxins like heavy metals and mold. When I went for the follow up appointment, my doctor seemed stunned. He said that in 15 years of practicing functional medicine, he had never seen bloodwork like mine. He said I was biologically decades younger than my chronological age, and asked what I had been doing lifestyle-wise. There wasn’t much to talk about during my appointment, so I told him all about my sauna :-) thank you thank you thank you, SaunaSpace for this amazing gift of health.

    Very Happy w This Red Light Sauna

    It took me over three years to make this purchase because I didn’t want to spend the money. Been dealing with chronic fatigue type stuff for over a decade - finally took advantage of a sale and ended up getting the the sauna space after deliberating spending more money for a clearlights sauna the program. I am on a program that recommends near infrared over far so went with this one. And this one was portable and more compact at a lower price point so I went with it! I’ve been using it for about two months now and I’m already feeling like I’m getting so much better. I have more consistent and reliable energy day to day. I started off with just 10 minutes a day because I went for 20 a few times and it wore me out. So I backed down to 10m at a time and now I’ve built up to 20 minutes a day and have the stamina to do it. This thing gets me sweating like no other sauna has before and I’ve been in all different types of saunas. It’s incredible how much you sweat. I do feel like this was a missing piece in my healing and truly feel

    It is healing me on a cellular level. I expect to continue improving. I will update this review in a few months.

    Also on a purely aesthetic level I will say it is so well done. The structure and appearance you can’t beat for something you need to put in a small

    Space. I know I could have thrown something red light together for less but the tent and solid light panel make it all worth it. So happy w this purchase and look forward to…

    Irreplaceable Tool for daily and weekly rituals

    I enjoy the SuperSauna experience almost daily, and it’s revolutionized my wellness rituals to the point where I am building a wellness community space with a circuit of practices that taps into this tool’s unique ability to have such an expansive impact on all of the systems of the body. Our cells and our bodies crave the healing power of this tool, and I couldn’t be more excited to share this with everyone I know.

    Missed my sauna while on vacation

    I may have missed my sauna just as much as my husband while on an extended vacation! It is so calming, and yet so invigorating. Looking forward to my next session tomorrow morning.

    My tiny sanctuary

    I have fallen in love with my tiny sanctuary. I use it after a work out as it will increase RBC production. There by mimicking altitude workouts. It’s a great way to sweat and reset. I like to sit there about 20 minutes and read a book. Preferably one you don’t mind getting sweaty.

The FireLight® Sauna FAQ

Got questions about the FireLight® Sauna? You’re not alone. From first-time users to seasoned sauna lovers, many are curious about what makes this full-spectrum infrared system so different. Below, we answer the most common questions about setup, sweating, safety, and why radiant near infrared light delivers a sauna experience unlike anything else. Whether you’re upgrading your detox routine or creating a healing space at home, you’ll find everything you need to get started, beautifully.

How is the FireLight® Sauna different from far infrared saunas?

Most saunas heat the air around you. Ours heats you directly.

Far infrared (FIR) saunas use longer wavelengths that warm the skin but don’t support photobiomodulation. The FireLight® Sauna uses incandescent near infrared light (700–1500 nm) that penetrates deeper, raises core temperature faster, and activates true cellular healing.

No LEDs, no flicker, no preheat—just real, radiant heat designed for detox and renewal.

Why canvas instead of wood?

Because it’s lighter, cleaner, and built for modern living.

Our natural canvas enclosure is portable, breathable, and tool-free to assemble—perfect for apartments, studios, or anywhere space is sacred. Unlike bulky wooden saunas, it won’t off-gas toxins, trap moisture, or grow mold over time. It’s washable, air-permeable, and naturally resistant to buildup.

But don’t mistake soft for weak. The double-layered canvas insulates like a pro, holding heat beautifully while staying gentle on your senses. With the SilverLining™ upgrade, it becomes a grounded Faraday space—fully shielded from EMFs and static.

It’s a return to simplicity: honest materials, intentional design, and a nervous-system-safe sanctuary that fits wherever you are.

Will I sweat—and how hot does it get?

Yes—and not just a surface sweat, but a full-body, cellular-level release that feels like the sun wrapping you in its arms.

Unlike traditional or far-infrared saunas that heat the air around you, the FireLight® Sauna uses radiant near infrared light (980–1500 nm) to heat your body directly. This thermal near infrared penetrates deep into tissues, raising your core temperature from the inside out—fast. No preheating required. Just step in, switch on, and the transformation begins.

Most people begin sweating within 5 minutes. In the Classic Sauna (4 bulbs), a full session is around 20–30 minutes. In the SuperSauna (7 bulbs), it’s even faster—closer to 15–20 minutes.

It doesn’t feel like steam or stifling air. It feels clean. Grounded. Regenerative. The kind of sweat your body remembers. The kind that heals.

What are the power requirements?

No electrician required.

Choose 120 V for North America or 240 V for international use. Both Classic and SuperSauna models plug into standard outlets with the correct adapter.

Why can’t I lie down in this sauna?

Because upright posture activates more than just your sweat.

The FireLight® Sauna is designed to engage your whole system. Sitting tall allows for better circulation, deeper light absorption, and more effective detoxification. It opens your breath, aligns your spine, and supports full-body exposure as you gently rotate.

Lying down may feel restful, but it reduces lymphatic flow, collapses posture, and limits the therapeutic reach of the light. Upright, you’re not just receiving warmth—you’re participating in the healing.

It’s not about being rigid—it’s about being awake. Present. Fully lit.

Do I need a special stool or chair?

Yes, and it’s included.

The Basswood Sauna Stool supports proper alignment and is handcrafted for comfort, breathability, and rotation. Once you use it, you’ll never go back.

Do I rotate during my session?

Yes—and it’s a core part of how FireLight® works.

Our saunas are designed for full-body exposure. As you gently rotate every few minutes, each side of your body receives direct, radiant near infrared light, no need for extra bulbs or longer sessions. Some people turn in quarters, others sway side to side. Let your body set the rhythm.

Rotation also creates natural thermal contrast: while one side warms, the other cools slightly. This activates circulation, enhances lymphatic flow, and drives the heat deeper into your tissues.

In the SuperSauna® (7 bulbs), most people reach a 3°F core temperature rise—and release about a pound of water—in just 15 minutes. The Classic (4 bulbs) takes closer to 20–30. No preheat, no steam—just real, radiant heat that moves with you.

How much does it cost to run?

Surprisingly little—for something that makes you feel so good.

The Classic Sauna uses 1000W, costing around 16¢ per hour.

The SuperSauna runs at 1750W—about 29¢ per hour based on average U.S. energy rates.

That’s less than a cup of tea—and far more rejuvenating.

Is it easy to set up alone?

Very.

Tool-free assembly takes 20–40 minutes. No drilling, contractors, or special skills required.

Watch the Classic Sauna setup video, and also the SuperSauna setup video.

What if I live in a small space?

You don’t need a spa wing.

The FireLight® Sauna was designed to fit beautifully into real homes—with a compact trapezoid footprint: 52” wide at the front, narrowing to 24” at the back. Whether you tuck it into a bedroom, guest room, office, or studio corner, it’s self-contained and easy to integrate.

Clean, low-profile, and plug-and-play—healing at home has never been this effortless.

What does it feel like inside?

Quiet. Warm. Grounding.

Natural materials, soft light, and a radiant glow that melts stress away. It’s like stepping into a sunlit cocoon.

Is it noisy or electronic?

Not at all.

No fans, buzz, or beeps—just silent, flicker-free incandescent light. Perfect for meditating or listening to music.

Do I need to wait for it to heat up?

Nope.

Flip the switch and step in. The bulbs deliver instant heat and light, zero preheat required.

Can I leave it set up all the time?

Yes. Its aesthetic and footprint work well in any room, and it’s easy to disassemble if needed.

Is it safe if I have heat or EMF sensitivity?

Yes, and even recommended.

The FireLight® Sauna heats you directly without stifling air. Add SilverLining™ for full EMF shielding and Faraday protection, ideal for those with EHS and for nervous system healing.

Can I use it while detoxing or fasting?

Absolutely.

FireLight® supports detox pathways, mitochondrial energy, and lymph flow. Just hydrate, support electrolytes, and ease in gently.

What should I wear inside?

Less is more.

Nude or light cotton is best. No synthetics—they block light and can off-gas.

When will I feel results?

Some feel better after one session.

Others notice deeper benefits over time: better sleep, fewer aches, improved mood. This is a practice. It builds.

How long do the FireLight® Bulbs last, and how do I replace them?

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.

The Sauna Builder is your personalized path to experiencing near-infrared light therapy at home. In just a few clicks, you can configure a complete setup that fits your space, your rhythm, and your wellness goals. Whether you’re creating a daily detox ritual or seeking deep relaxation, this tool makes it easy to design a healing environment that feels intentional and alive.

Every component is handcrafted for purity, performance, and ease of use. From our signature light therapy panels to the shielding and enclosures, each element is engineered to support full-body renewal without synthetic materials or hidden stressors. The spectrum of light delivered supports cellular regeneration, detoxification, and calm—without EMFs, flicker, or artificial stimulation.

If you’re new to infrared therapy or unsure where to begin, we recommend starting with our SaunaSpace 101 guide. It covers everything you need to know about light and heat therapy, including how it works, what makes near-infrared unique, and why so many people are turning to this technology for resilience, energy, and deep rest.
