FLEXIBILITY BY DESIGN

A Serious Plunge Without a Permanent Footprint

Full-Body Horizontal Tub

The 6.4-foot horizontal profile supports full-body immersion and comfortably accommodates taller users, while the inflatable structure weighs a fraction of a permanent basin.

Insulated Tub + Lid

Insulated walls and the fitted cover slow temperature gain, reduce demand on the chiller, and help keep debris out between sessions.

Packable System

The tub deflates for transport and stores with its air pump, hoses, repair kit, filter tools, and carrying case, making serious cold immersion possible without a permanent footprint.

Standard GFCI Power

The complete system plugs into a standard household outlet (NEMA 5-15) on a dedicated 120V, 15A GFCI circuit, with no plumbing, hardwiring, or separate mechanical room.

What to Know Before Your First Plunge

01 Prep the Site

Pick a flat surface rated for the filled weight, keep 36 inches of airflow around the setup, and place the chiller with its fan facing away — at least 40 inches from the tub or any wall.

02 Plan the Power

It plugs into a standard wall outlet (NEMA 5-15) on a dedicated 120V, 15A GFCI circuit. If that circuit is already in place, no electrician or special wiring is needed.

03 First Fill

Let the chiller stand upright and unplugged for 4 hours before first use — the refrigerant needs to settle after shipping. Then inflate, fill, and confirm water is flowing from the jets before you go further.
