Description

The Theralpine Rhone ice bath provides insulation that maintains cold water for several days, minimizing cooling requirements. The compact footprint suits limited spaces like homes, balconies, or gyms, while ergonomic back support and capacity for users up to 2m tall ensure accessibility. Ground-level entry and anti-slip floor enhance safety. Constructed from premium-grade polyethylene with UV resistance, it supports indoor and outdoor placement and features dual ports compatible with standard chiller connections.

Theralpine Chiller Pro and Lite integrate for temperature control, filtration, and app-based operation, with corrosion-resistant builds that are compatible with fresh water, chlorine, and Epsom salts. Be sure to check out real-life test Theralpine performed on their cold plunge with Pro chiller.

Lite and Pro chillers both have a larger particle filter integrated and come by default. If you want a 20-micron main filter with cartiridges support, you need to buy it as an optional part (housing) for the Lite chiller.

Frequently asked questions

Yes — the Rhone is a complete system that includes a built-in chiller. No separate cooling unit is required; you can start cold therapy as soon as it is set up and filled.

The Rhone is a horizontal cold plunge designed for seated or reclined immersion, similar in form to a bathtub. This is the most common orientation for home cold therapy setups.

The tub basin of the Rhone is made from Polyethylene.
