What to Look for When Buying a Cold Plunge Tub

Buying your first cold plunge can be a little overwhelming.

There are inflatable tubs, stock tanks, compact plunges, large tubs and complete systems with chillers and filtration.

So how do you know what is actually worth paying attention to?

Here are a few things we recommend looking at before you buy.

Size Matters

This might seem obvious, but make sure the cold plunge is actually comfortable for you.

If you are taller, you want enough room to sit comfortably without feeling completely cramped.

The Frozin 400 holds approximately 100 gallons of water and is designed for users up to 6 feet 3 inches and 300 pounds.

Think about your own height and build before choosing a tub.

Pay Attention to Insulation

If your goal is cold water, you want your tub to be able to hold onto that cold.

Good insulation helps reduce heat transfer from the surrounding environment.

This can be especially important during hot weather.

The Frozin 400 features full foam insulation and a durable roto molded construction.

Do You Want a Chiller?

This is another big decision.

You can absolutely use ice to cool your water, especially if you are just getting started.

But if you plan on cold plunging regularly, buying bags of ice every few days can get old quickly.

A chiller lets you maintain a consistent water temperature without constantly adding ice.

The Frozin 400 is designed to be chiller ready, so you have the option to add one to your setup.

Think About Where You Will Put It

Before you order your cold plunge, think about where it is going.

A backyard is a popular option, but garages, patios and home gyms can work too.

Make sure you have enough room around the tub and access to whatever power and drainage your setup requires.

Think About Maintenance

A cold plunge is something you are going to use repeatedly, so you want to think about cleaning and water maintenance before you buy.

A good filtration system can make maintaining your water much easier.

If you want an all in one setup, the Frozin Complete Cold Plunge System combines the Frozin 400 with a chiller and filtration system.

Buy for the Routine You Actually Want

The most expensive cold plunge is not automatically the best one for you.

Think about how often you plan to use it.

If you want to experiment with cold plunging once in a while, a simple setup may be enough.

If you already know you want to make it part of your weekly or daily routine, investing in a durable, insulated tub with chiller compatibility may make more sense.

The right cold plunge is the one you will actually use.

And that is what matters most.
