Premium infrared therapy meets cutting-edge technology—featuring the industry’s lowest EMF/EF levels, smart controls, and tool-free assembly that transforms any room into a wellness sanctuary in under an hour.
In a market flooded with cheaply-built infrared saunas that compromise your health with dangerous EMF levels, the Finnleo S-Series stands alone.
This isn’t just another infrared sauna—it’s a complete reimagining of what home wellness technology should be. With independently verified low EMF/EF emissions, smart home integration that lets you control your sauna from anywhere in the world, and Canadian hemlock construction free from harmful VOCs, the S-Series delivers the therapeutic benefits you want without the compromises you shouldn’t have to make.
When you’re ready for infrared therapy that’s as safe as it is effective, this is where you begin.
The S-Series isn’t just about infrared heat—it’s about creating a complete wellness experience that fits seamlessly into your daily routine. Every feature has been engineered to deliver maximum therapeutic benefit with minimum complexity.
Third-party tested by Intertek for your peace of mind.
While other infrared saunas bombard you with electromagnetic fields that can negate health benefits, our CarbonFlex™ panels emit virtually undetectable levels—lower than your cell phone or laptop—ensuring pure, safe infrared therapy every session.

Start your sauna from bed, work, or across the world. The InfraLogic 2.0 control system with SaunaLogic app transforms your phone into a command center—schedule sessions, adjust temperature, control lighting, even monitor energy usage—making daily wellness as convenient as checking your email.
The S-Series features oversized infrared panels surround you on all three walls, under your bottom, in front of your calves, and under your feet. This gives an even heat distribution in the room, eliminating the cold zone problem.
You can control whether the bench, calf or feet emitters are on or off with the Infralogic 2 Control or your smartphone.
The S-Series Infrared Saunas have bluetooth speakers so you can enjoy music, podcasts, and books while you bathe in the sauna.
Set the ambience with LED RGBW strip lighting. The lights are dimmable and are controlled with the InfraLogic 2 Control or the SaunaLogic App on your phone.
The S-Series is about as easy as it comes in terms of assembly, which can be done in less than an hour with two adults.
The walls are pin & hook assembly and the bench(es) slide into place.
No tools are required for assembly.
The S-Series is built with Clear Canadian Hemlock, harvested responsibly.
There are no VOC’s in the S-Series Saunas. VOC’s are harmful toxins found in glue, which may be in other brands of saunas.

These infrared saunas are easily assembled, anywhere in your home, provided you have access to standard household power.
The major selling point, aside from having the lowest EMF / EMR infrared panels in the world, is due to the ease of installation.
Our Infrared Saunas are easy to install yourself, or for a totally hands off experience, have our sauna installation professionals take care of it for you.
Our CarbonFlex™ panels use a unique carbon fiber configuration that naturally minimizes electromagnetic fields. Third-party testing by Intertek confirms our EMF levels are below 2 milligauss—compared to 50-100+ in many competitors. This is lower than your smartphone, laptop, or even household appliances. We provide the full test report so you can see the exact measurements yourself.
If you can slide a puzzle piece into place, you can assemble an S-Series sauna. The panels literally hook together—no screws, no tools, no measuring. The illustrated guide shows every step, and most customers are surprised how simple it is. Watch our assembly videos to see real customers (not professionals) putting them together. If you prefer, our installation team can handle everything for a nominal fee.
Yes! The InfraLogic 2.0 connects to your home Wi-Fi, letting you control your sauna from anywhere with internet. Start heating from work, adjust temperature from bed, or check if you remembered to turn it off while on vacation. The app also tracks usage, schedules recurring sessions, and even reminds you when it’s time for your daily wellness routine.
It includes a strong warranty 5-year warranty from Finnleo. Tech support is based in Cokato, MN.
Beyond capacity, consider: (1) Power requirements—some need dedicated 20-amp circuits, (2) Configuration—forward-facing vs. corner units affect room placement, (3) Features—all have the same smart controls and low EMF, but larger models have more heating zones. Most customers choose based on available space and whether they’ll use it solo or socially. Our team can help you decide based on your specific situation.
Models S-810, S-820, and S-870 plug into any standard 15-amp outlet—no electrical work needed. Models S-825, S-830, S-840, and S-880 need a 20-amp dedicated circuit, which most homes have in laundry or kitchen areas. All models use standard 120V power, not 240V like traditional saunas.
