Two years in development. One goal: make heat therapy as non-negotiable as cold.
Plunge built its name on cold. Now it's coming for heat.
The Infrared Sauna is Plunge's next evolution of recovery — a full-body infrared sauna built on a dual infrared system, pairing far-infrared panels with full-spectrum incandescent towers to surround the body in deep, even heat instead of the uneven warmth typical of single-panel saunas.
It comes in two versions, and the difference isn't cosmetic — it's about how hard you can push it:
Both share the same cabin: premium Canadian hemlock, no toxic glues or resins, a near-zero EMF rating, and clean interior lighting. The difference is in ceiling temperature and what you're able to add on. If you want to run hotter sessions and eventually add red light therapy, Pro is the only version that supports it. If you just want consistent, research-backed heat exposure without rewiring your house, Standard gets you there.
Both are available in 2-person and 3-person sizes.
Heat has always been the quieter half of contrast therapy — the part people skip because the format was inconvenient. A dedicated hot yoga studio membership. An expensive spa visit. A traditional sauna that takes forever to heat up and offers nothing else to do while you wait.
Plunge is removing the friction. The app controls preheating and scheduling, so the sauna is already at temperature by the time you step in — morning session before work, evening reset after training, no waiting around. A 10-degree tilted wooden backrest supports a more natural, restorative posture for longer sessions. Integrated Nakamichi Bluetooth speakers, engineered to perform in extreme heat, turn a solo sweat into something closer to a ritual. A 360-degree chromotherapy LED ring — customizable through the app across cold gradient, hot gradient, purple, and blue — wraps the interior in color.
And critically, it's built to pair with cold. Commercial-grade durability, a premium butcher block bench, and a waterproof silicone floor mat mean the unit stays intensely hot even after repeated cold-to-hot sessions — the entire cabin engineered around contrast therapy, not just heat alone.
Sauna use isn't a wellness trend. It's one of the more heavily studied recovery interventions in modern research.
Frequent sauna bathing has been linked to a 63% lower risk of sudden cardiac death and a 40% reduction in all-cause mortality risk, according to a 20-year Finnish cohort study published in JAMA Internal Medicine. A separate study in Age and Ageing found frequent sauna use associated with a 66% lower risk of dementia. A systematic review in Evidence-Based Complementary and Alternative Medicine covering 40 clinical studies backs up the broader pattern: heart health, brain health, and longevity benefits, all tied to consistent heat exposure — most of it studied at temperatures around 175°F, the same ceiling the Pro model is built to hit.
Plunge spent years making cold exposure a mainstream home habit. The Infrared Sauna is the other half of the equation — and a signal that the brand isn't positioning itself as a cold plunge company anymore. It's positioning itself as the full recovery platform: heat and cold, engineered to work together, controlled from one app.
"Heat. Cold. Recovery. Built by Plunge."
