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!

Customer Reviews
I was one of the first customers, back when it was Arctic Cold Tubs. I have had my tub for nearly 3 years, and this thing has been a staple for me. My wife and I use this almost every day, here in Arizona. We have not had a single issue with the tub. It is super easy to maintain, it’s always cold at our 44° temperature, and the water is always super clean. I cannot recommend this company or this product enough!
Love letting my friends use this. Its a beast.
I bought because of a review from David Maus Jr, and I couldn't agree more with what he said "It's a tank".
The OG tub is basically perfect. High flow, easy setup, and super easy to maintain. Water stays crystal clear.
It's clear a lot of thought went into the design. It's simple, yet built like a tank!
