Key Features & Design

• Weight & Mobility — Weight around 400 lbs; can be moved by two people or with trolleys.
• Water Capacity & Height — Takes approximately 60 gallons of water; water height is adjustable based on body displacement and how high you want it to reach (neck/chin height is easily achievable).

• Chiller & Pump — 1/4 hp pump with 950 GPH; adjustable temperature control for reliable cooling.
• Water Sanitation — Natural purification via an ozonator emitting O3, providing effective water treatment.
• Electrical & Setup — Typical power usage 350–500 Watts @ 3–5 amps on a regular 110-volt plug; plugs into a normal home outlet. Outlets should be GFCI or grounded as required by state laws.
