Our cold plunge tubs represent the best of years of engineering and design work.

Our Original Cold Plunge comfortably fits big and tall people as tall as 6’8″ with full over-the-shoulder cold water immersion. It is widely loved throughout the cold plunge community for its affordability, energy efficiency, consistent chill temperatures, child-proof features, and because we go out of our way to make sure our customers are well supported through their cold plunge journey.

Our Wide Grizzly 450 Cold Plunge is 7.5″ wider, an inch longer in the interior, and shallower. It is ideal for people who like to sit crosslegged when cold plunging; who would like to cold plunge with someone else; or for men with very wide shoulders / who have more of a football player physique. Our wide cold plunge has even greater insulation that the original for even better energy efficiency and faster cooling.

In optimal conditions (stored inside under climate control or outside out of direct sunlight and kept under cover) both our Original and Wide cold plunges get down to 39 degrees, no ice needed.

Horsepower refers to the ooomph of your chiller, the element that keeps your cold plunge cold.

Our ¼ hp chiller, used on both our Original and Wide Cold Plunges, can cool to 39 degrees. Due to the amazing insulation of our tubs and quality of our ¼ hp chillers, this chiller is energy efficient and works great for most people. This model chills best when kept out of direct sunlight in intense heat.

You will need a standard 100V outlet to plug your cold plunge into; it draws 6.5 amps while chiller is running.

If your cold plunge tub is kept at 45 degrees during an Arizona summer, it will cost you roughly $25/month depending the price you pay per kWh with your local utility company.

Be sure to rinse off well before getting in your plunge. Makeup, soap, lotions, and oils from your body will affect the sanitation of the water.

Only wear a swimsuit in your plunge, anything else is not recommended. Lint and laundry detergent soap will come off your clothing, causing the water to get dirty faster.

Put a mat down in front of your plunge. Don’t walk from where you rinse off to the plunge barefoot, where sandals and take them off right before you get in.

You can try using a “scum bug” to help soak up some of the oils. Also adding 35% food grade hydrogen peroxide (4.5 oz) will help with water sanitation.

Some other good options for sanitation are a chlorine free water stabilizer or our Sirona spa water treatment kit.

You can also purchase a spa vacuum from Amazon to help suck up some of the loose debris that may fall to the bottom of your plunge.

The only time we recommend adding ice to your cold plunge tub is in the summer in hotter climates, to help speed up the cooling time on initial fill up of your tub or during a water change, because you just can’t wait to get in. Be sure before turning on your plunge that the ice is floating well above the intake hole.

Yes, but there are special considerations for your tub needed in cold temperatures. We recommend keeping your tub under cover and away from direct sunlight for long periods of time.
