Full Side-by-Side Comparison
- Founded 2020 in Southern California after the founder's cold-immersion experience on a ski trip
- Handcrafted in California — not an imported or mass-produced tub line
- Five tank models spanning $5,950 (Vero) to $12,849 (Siberian Pro) — premium tier, not budget
- Chiller performance and control interfaces vary by model: 0.25–0.8 HP, touchscreen+app or built-in dial controls
- Portable, tent-style far infrared sauna with a head-out design — not a cabin sauna

- Also sells standalone FIR lamps, a Flex Lie Down Sauna variant, books, and replacement parts
- Uses PTC semiconductor heating elements, marketed by the brand as "medical-grade" and "almost 100% pure" FIR output (brand-authored claims)
