Your Full Spectrum Infrared Sauna
After a long day, step into a full-spectrum infrared sauna experience designed to support deep relaxation, recovery-focused routines, and everyday restoration. The Tosi full spectrum infrared sauna reaches deep into muscles, joints, and core tissues - relieving tension, accelerating recovery, and supporting skin health.
Across the Tosi collection, models are crafted in Canadian red cedar or Canadian hemlock, depending on the sauna. Each is paired with ultra-low EMF technology and a modern modular design that transforms your space into a personal wellness sanctuary.
“Love my new tosi full spectrum cedar sauna. It is very well built and easy to assemble. It has become part of my daily routine and feel great. Customer service was very helpful in answering all my questions prior and after ordering.”

Tosi brings near, mid, and far infrared together in one full-spectrum sauna experience, creating a layered heat profile across surface, muscle, and deeper-feeling warmth.
Skin & surface tissues
Supports collagen production, skin repair, and cellular regeneration
Muscles & joints
Increases circulation, reduces stiffness, and helps relieve soreness
Core & deep tissue
Promotes deep sweating, supports cardiovascular health, and reduces muscle tension
Instead of relying on a single wavelength, Tosi uses near, mid, and far infrared together for a more complete recovery-focused sauna experience. Its near-infrared output is delivered through targeted LED emitters.
When all three wavelengths are used together, the benefits go beyond simple heat:
Surface
Skin rejuvenation and cellular repair
Muscle
Improved flexibility, circulation, and recovery
Core
Deeper sweat, relaxation, and full-body relief
Together, these wavelengths work in harmony to support your body on every level-from the skin to muscles to your core. The result is more than just warmth; it’s a full-body recovery experience you can feel.
The Tosi collection includes full-spectrum sauna models in two heat ranges - chosen to match the way you actually want to use the sauna at home.
Classic Infrared Heat
Up to
Gentle, comfortable, and designed for repeatable daily sessions.
High Heat Infrared
Up to
Stronger, more intense cabin heat for buyers who want a more demanding sauna experience.
Both ranges are intentional design choices. The right Tosi model depends on the heat experience you want at home.
