3 Reasons Why Thousands Are Choosing Caldera Over Traditional Saunas
Infrared heat, red/NIR light, and at-home access create a deeper, more consistent sauna experience than the occasional gym or spa session.
Engineered For Longer Heat Exposure

Longer exposure to full-spectrum infrared heat and built-in red light therapy gives your body more time to relax, recover, and recharge.
Supports deeper recovery after every session
Helps your body unwind before bed
Supports a more relaxing evening routine
Helps you wake up feeling recharged
Delivers Heat Directly To Your Body
HEATS YOUR BODY DIRECTLY
Traditional saunas mainly heat the air, Caldera full-spectrum infrared heat warms your body directly while the built-in red light therapy helps support recovery, relaxation, and waking up feeling recharged.

Your Body Needs More Than One Type Of Heat

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.
