This is our third sauna in 20 years, and the single-person Relaxe Caldera is a fantastic choice. Assembly was easy; I identified the parts and put it together in about 2-3 hours. The use model is great—just set the temperature, time, and lighting, and you're good to go. You can connect it to your phone via Bluetooth for music, podcasts, or audiobooks. The Himalayan salt tray and red light therapy panel are excellent additions. We also love the app for controlling the sauna, and surprisingly, our devices didn’t shut down from the heat inside.

This sauna is excellent, especially the red light therapy board. It heats up to 145 degrees in about an hour, and I can push it to 149 with an extra 20-30 minutes. Even at 125-130, you can still sweat well. The speakers are great, and with Bluetooth, you can use your phone or iPad for entertainment. We got the 2-person sauna, which has plenty of space for my wife and me. It arrived well-packed, and the driver helped wheel it into our garage. Everything was lightweight and easy to carry to our basement.

I was hesitant due to the low price, but assembly took me about two hours alone. Mounting the red light panel was the hardest part. I regularly use both the infrared sauna and red light therapy panel without issues. The sauna reaches 142 degrees and is in our bedroom. You can place the towel rack and cup holder anywhere, but I suggest trying it out first. I plan to recommend these to my clients if I stay issue-free for the next six months.

We bought this for my husband and my son who is a wrestler who needs the sauna often for many reasons. We are loving it so far and love that we can connect to Bluetooth to enjoy a podcast or some music while we do some recovery time. The red light is amazing! I’m in my 40s and have always wanted therapeutic red light for face and body. We highly recommend the product.

We love it... been using it after workouts, before bed, or just when we feel like it. Love the bluetooth and red light therapy. I use the red light almost everyday, even if I don't sauna.

Frequently Asked Questions
The Caldera ships in clearly labeled flat-pack boxes that fit through standard doorways. Most customers complete assembly in 45 minutes to 1 hour — no contractor, no electrician, no special tools required. It runs on a standard 120V household outlet.
It means you have a full year to try the Caldera in your home. If you're not completely satisfied, we'll arrange a free return and full refund — no questions asked, no restocking fees. We offer this because we believe in what the product does once you use it consistently.
Traditional home saunas heat the air around you to 180–200°F. The Caldera uses full-spectrum infrared — three wavelengths that penetrate directly into muscle and joint tissue at lower, more comfortable temperatures. It also includes the LumaPanel, an integrated red light therapy panel delivering 660nm and 850nm wavelengths that most competitors sell separately.
The Caldera is designed for daily use. It operates at a lower ambient temperature than traditional saunas (64–149°F) while delivering more effective tissue response. Its low-EMF design meets standard household compliance. If you have a specific medical condition, we recommend consulting with your physician before beginning regular sauna use.
The LumaPanel is the Caldera's built-in red light therapy panel. It delivers 660nm red light for skin and surface tissue, and 850nm near-infrared for deeper cellular recovery. It's included with every Caldera — no separate purchase required. Recovery clinics charge $50–100 per standalone red light session. In the Caldera, it runs every session.
You can finance your Caldera starting at $139/month through Affirm. Checking your rate takes seconds and has no impact on your credit score. Select Affirm at checkout to view your options.
The Caldera is covered by a 3-year warranty. If anything goes wrong, we handle it — fast replacements, responsive support, no runaround. Our customer support team is staffed by humans, not bots.
The 1-person Caldera measures 35.4" L × 43.3" W × 74.8" H. It ships in flat-pack boxes sized to fit through standard doorways. No dedicated room or structural modification required. We recommend having 6–12 inches of clearance around the unit for ventilation and comfort.
The True Cost of Premium Wellness
At Relaxe, we don’t inflate prices just to advertise fake discounts.
When you see Total Value, that number represents the real-world combined value of the Caldera™ sauna and everything included
What Is “Total Value”?
The Total Value reflects what it would cost to build this sauna using:
9 carbon fiber heaters
Full-spectrum infrared + dual wavelength red light
Low EMF technology
Canadian hemlock frame
365-day in-home trial
3-year warranty coverage
When purchased separately, these features often exceed the Total Value listed.
We price Caldera™ below the combined market value — so you receive true savings, not marketing discounts.
