Winthera Flex

DESCRIPTION

The Winthera Flex Ice Bath is a portable, lightweight cold-therapy tub designed for anyone seeking the benefits of cold immersion without committing to a permanent installation. Thanks to its durable yet flexible construction, the Flex lets you enjoy professional-style cold therapy at home, outdoors, or wherever suits you best. It’s ideal for athletes, wellness enthusiasts, or anyone wanting an easy way to integrate cold plunges into their routine.

Flexibility, portability, and convenience are at the core of this model — when paired with a compatible chiller (or simply filled with cold water and ice), it provides a reliable cold plunge solution that can be set up quickly and stored away when not in use.

FEATURES 

The Winthera Flex is portable and lightweight, built from high-strength drop-stitch PVC. Weighing only 16 kg when empty, it remains rigid and stable when filled. Its durable, weather-resistant construction makes it suitable for indoor or outdoor use year-round.

The spacious interior comfortably accommodates users up to approximately 2 meters tall. When paired with a compatible chiller, the Flex can maintain cold water temperatures and even form a surface ice layer for an enhanced cold plunge. A fitted cover is included to retain temperature and improve energy efficiency.

With a compact footprint and inflatable design, the Flex is easy to store when not in use. Setup is quick and simple — inflate (if using a pump), connect to a chiller, fill with water, and your cold plunge is ready.

INCLUDES

The Winthera Flex inflatable cold-plunge tub is made from durable drop-stitch PVC and comes with a fitted insulating cover to help retain temperature. It includes a drainage plug at the bottom for easy emptying, along with assembly and setup instructions for a plug-and-play experience. Please note that a chiller, such as the Winthera Ice Master, or ice with cold water must be used separately to achieve and maintain low temperatures.

TECHNICAL

The Winthera Flex features a modular design, with a rugged drop-stitch PVC structure that inflates into a stable, rigid tub and deflates for compact storage. When connected to a compatible chiller unit (sold separately), it supports efficient cold-water cooling, allowing users to achieve plunge-ready temperatures with ice-bath setups. Its durable, outdoor-ready construction tolerates a range of conditions and colder seasons, making year-round use possible when properly sheltered. The included cover helps maintain water temperature, conserve energy, and minimize heat loss, especially when chilling water.
