What Sets the OG Apart
Performance-focused engineering. Everyday reliability.
The OG moves more water than any plunge in its category — delivering stronger circulation, colder sessions, and consistently clean water. Better flow means better cold therapy, and the OG is unmatched at this level.
Built with a ½ HP commercial chiller, oversized filtration, and high-flow plumbing normally found in higher-tier models. Every core component is engineered for reliability, not shortcuts.
Hand-assembled in the USA using reinforced framing, superior insulation, and a fully self-contained cabinet. The OG is designed to handle daily use and extreme climates with ease.
Strong circulation and insulation maintain stable temperature with less energy load. The roomy interior provides natural, full-body immersion without feeling cramped.
Just fill, plug in, and plunge. Ozone and oversized filtration minimize maintenance, while accessible components make quick checks or filter swaps effortless.
