Frozin 400 Cold Plunge
The Frozin 400 Cold Plunge is available in two configurations: an insulated tub for customers building their own cold-plunge setup, or a complete system with Frozin's matched cooling, circulation and filtration components. The USA-built tub uses a UV-resistant reinforced shell, substantial insulation and straightforward plumbing connections for a durable, purpose-built cold-therapy setup.
