Why Choose Frozin
What Sets Us Apart From the Competition
When it comes to cold therapy, performance matters — but simplicity matters even more. Here's how Frozin Cold Plunge stands above the rest:
Built for Simplicity
Our system features advanced quick-connect technology, making it one of the easiest cold plunges on the market to assemble. No plumbing expertise. No complicated setup. Just connect, plug in, and you're ready to go.
True Plug-and-Play Convenience
We deliver a complete, ready-to-run system — not a collection of separate parts. From filtration to cooling, every component is engineered to work seamlessly together right out of the box.
Mess-Free Maintenance
Changing a filter or cleaning a strainer shouldn't leave water all over your floor. Frozin's design allows for little to no water spillage, keeping your space clean and stress-free during routine maintenance.
Superior Insulation = Superior Performance
Our tub is constructed with 2 inches of high-density foam insulation, plus a fully insulated lip to lock in cold temperatures. The result:
- More stable water temperatures
- Improved energy efficiency
- Reduced cycling on your chiller
- Lower long-term operating costs
Engineered for Reliability
Every Frozin system is thoughtfully designed to deliver consistent cold, efficient performance, and long-term durability — so you can focus on recovery, not maintenance.
Frozin Cold Plunge — Effortless setup. Clean maintenance. Cold that lasts.

What Our Customers Say
Purrrrrrfect Cold Plunge Tub
My inflatable cold plunge tub kept having problems and I wanted to get a hard shell. This was the most affordable one that looked decent so I pulled the trigger. Very solid. The hooks ups fit my existing tubing from a previous cold plunge build with no leaks at all. I'm 6 foot tall, 250 lbs and it was the perfect size for me as well. Highly recommend.
Great tub and great value!!!
Wonderful value for the price. It is well insulated and had an insulated lid. Had my chiller hooked up in no time and have had no issues at all. I highly recommend this tub.
Excellent Cold Plunge Tub & Chiller!
This is my first ever review that I have posted on Amazon since my prime memberships years ago! Why now? The Staff & Ownership of Rezvani Frozin are exceptional! I ordered this COLD plunge tub with its chiller and immediately the seller reached out to me about the delivery. Furthermore, they contacted me upon delivery and then worked with me to ensure that everything worked properly. The water pump did not work properly and immediately they replaced it, and Tom one of the owners contacted me to ensure that I received it and that everything was working properly. As a military retired Soldier, I understand professionalism, pride of ownership and loyalty to its customers and the folks at Rezvani Frozin are just that! The best valued professional cold plunged in amazon...less that 2K works great and looks great in my garage! Thank you!
Great
Great purchase and seller has great customer service and support!
Ice Only Plunger
Love this Frozin 400 tub!! I just use ice for my cold plunge and don't want to add a chiller. I upgraded from an uninsulated tub and feel I made a great choice. I've been able to maintain my desired 50+- degree temp range by putting a couple large blocks of ice in every 5 days or so. The tub is comfortable and plenty big enough to get fully immersed and to dunk my head. (5'10"). The lid fits snug, and is decently heavy, but is easy to take off and set aside. The owner has been great as well on following up on satisfaction. Tub came several days earlier than expected which was a bonus. I've been very happy overall with this purchase and glad to save a few bucks from a large general purpose cooler.
Perfect for ice bath
Good size for someone under 6ft, ice bath does not sweat, prefilled holes and brass fittings work perfectly with 3/4 in pvc fittings, definitely recommend!
