What Sets Our Tubs Apart
Commercial-Grade Build
Every detail has been built to include the strongest, most durable components, to ensure reliability and durability!
Chilling Down to 36°
Our 1hp Heavy-Duty chiller (Japanese engineered) cools water to 36°, cold enough for even the most advanced cold plungers! (Don’t worry, it’s adjustable - so you can work your way down if needed!)
High-Powered Flow Rate
Our industry-leading Flow Rate helps break through your thermal barrier, so you feel the true temperature of the water! This high flow also keeps your water cleaner, clearer, and colder!
Indoor or Outdoor
The OG was designed to be put anywhere, even outside in the blazing Arizona heat!
3-Stage Water Cleaning Process
Includes the following features:
- Overpowered Flow Rate, completely turns water over every 3-5 minutes.
- UV Ozone Sanitation oxidizes and breaks down unwanted contaminates and helps to maintain water quality
- 20-micron Filtration pulls our hair, skin, and other debris from the water
Plug and Play
The OG plugs into a standard 110V GFCI protected outlet.
*Dedicated 15 amp breaker needed for Heavy-Duty 1HP models*
Easy Setup: No Plumbing Required
The OG was designed to be self-contained. Once filled with a hose, the water inside the tub will last upwards of 6 months without needing to change it! If needing to drain, attach a hose to the pump-fed drain and your tub will be empty in 8-10 minutes!
Unmatched Durability
The OG Cold Tub is a high quality acrylic tub with fiberglass reinforced steel framing.
Fully Insulated
Think of an OG Cold Tub as a Yeti! We use a high-quality spray foam to help preserve the water temperature inside your tub!
