What a Cold Plunge Actually Costs Once You Add the Chiller

Most cold plunge tubs are sold as a vessel. The refrigeration unit that holds the water at 37°F is a second product with its own price tag, and it is usually the expensive half.

• 10 of the cold plunge tubs we list ship without a chiller. They run from $699 to $5,999.
• We list 4 chillers, and they run from $3,299 to $3,699. That is a $400 spread against a $5,300 spread on the tubs, so the chiller is close to a fixed cost no matter which tub you put under it.
• The least expensive chiller costs more than 5 of the 10 tubs. If you are budgeting from the tub price, you are budgeting from the smaller number.
• The cheapest chilled setup we can build is $3,998, a $699 inflatable under the $3,299 chiller.
• If you would rather not do the arithmetic, 2 products already arrive matched: the Dynamic Barrel Cold Plunge System at $5,598 and the SaunaLife Model S2NC Package at $7,815.

If ice is still on the table for you, our cold plunge tub buying guide works through ice versus chiller on running cost. This post assumes you have decided you want chilled water and just want to know the bill.

A chiller is a compressor, a pump and a heat exchanger. It sits outside the tub, pulls water out through one port, drops the temperature, and pushes it back through another. Nothing about that is specific to one vessel, which is why manufacturers build the two separately and let you match them.

That is good for you in one way and bad in another. Good, because you can put a $3,299 chiller under a $699 inflatable this year and move it to a $5,999 stainless cuboid in three years without buying refrigeration twice. Bad, because a tub listing can honestly say $2,299 while the working setup is $5,598, and nothing about the photograph tells you which number you are looking at.

Our own listings say so in the description text. The barrel tubs carry a line reading that chillers must be purchased separately and do not come with an order of "Just The Tub", and the DCT Inflatable Round Cold Plunge is named "(Tub Only)" for the same reason. It is stated, but it is stated in the middle of a paragraph, which is exactly where a shopper comparing two price tags will miss it.

Two exceptions worth knowing. The SaunaLife immersion tubs are usable with ice from day one, so the Model S1N at $3,485 is a real tub at a real price without a chiller. And the chillers we sell are cold and heat units, so the same box that holds 37°F also runs a warm soak up to 85°F, which changes the value calculation if you were also pricing a hot tub.

These are the current listed prices for everything in our cold plunge range. Tubs first, cheapest to dearest.

Now the chillers. Note how close together they are.

The chiller range is $3,299 to $3,699. Whichever tub you choose, you are adding roughly $3,300 to $3,700 to reach chilled water, so the honest floor for a chilled plunge in our catalog is $3,998 and the honest ceiling is $9,698.

Path one, buy the vessel cheap and put the money into refrigeration. Put a $699 inflatable under the 0.8 HP chiller at $3,299 and the pair comes to $3,998, which gives you the same water temperature as a setup costing more than twice that. The tub is the part you will want to replace later; the chiller is the part that carries over. Our own listing for the inflatable says as much, describing it as the most affordable way to put a vessel under a DCT chiller.

Path two, buy it matched. The Dynamic Barrel Cold Plunge System is $5,598, which is the same total as the $2,299 oval barrel plus the $3,299 chiller. You are not paying a premium for the pairing, you are buying one line item instead of two and skipping the compatibility question. The SaunaLife Model S2NC Package at $7,815 does the same thing at two-person scale with a combination chiller and heater.

Path three, buy the tub now and the chiller later. This is the one people actually do, and it is fine as long as you say it out loud. The DCT Oval Barrel Tub at $2,299 ships without a motor precisely so it can be run on ice first and plumbed to a chiller later. Just do not budget $2,299 and expect chilled water; budget $2,299 now and $3,299 or more when you get tired of buying ice. The running-cost comparison between ice and a chiller is worked through in our buying guide.

Financing is available at checkout, subject to approval, which is worth knowing on a two-part purchase where the second part is the larger one.

Once you accept the chiller as a separate line, the next question is which one. The spread is only $400, so this is a smaller decision than it looks.

Capacity is the first filter. The Premier Edition 1.0 HP at $3,699 is specified for plunges up to 135 gallons and pulls water down 1–3°F every 20 minutes. The Premier Edition 0.8 HP at $3,499 covers the same 135 gallons but takes about 30 minutes to move the same 1–3°F. Both reach the same 37°F floor and the same 85°F ceiling. The 1.0 HP is buying you time, not colder water.

Ambient temperature is the second. An undersized chiller in a hot garage runs closer to continuously, which costs more to operate and works the compressor harder. If the plunge lives outdoors in a warm climate, the extra $200 for the faster unit is the cheaper decision over a few summers.

Then features. The Premier units add ozone sanitation and two-stage filtration on top of the WiFi app control the whole line carries. That is water quality rather than temperature, and it changes how often you drain and refill rather than how cold you get. If you are running a contrast setup where the same tub does hot and cold, our contrast therapy guide covers the sequencing.

If you would rather not size it yourself, tell us the tub, the gallons and where it is going, and our US-based advisors will match it. The quote page is the fastest route.

Does a cold plunge tub come with a chiller?

Usually not. 10 of the cold plunge tubs we list ship without one, and the tub descriptions state that chillers are purchased separately. Two products in our range do arrive matched: the Dynamic Barrel Cold Plunge System at $5,598 and the SaunaLife Model S2NC Package at $7,815, which includes a combination chiller and heater.

How much does a cold plunge chiller cost?

Between $3,299 and $3,699 across the 4 chillers we list. The range is narrow on purpose: the compressor sizes are close together, so what separates them is cool-down speed, ozone sanitation and filtration rather than the temperature they reach.

What does a complete cold plunge setup cost?

From $3,998 to $9,698 if you buy the two pieces separately, which is a $699 inflatable with the $3,299 chiller at the bottom and the $5,999 stainless CUBOID XL with the $3,699 Premier 1.0 HP at the top. A matched package is $5,598 or $7,815.

Is the chiller more expensive than the tub?

On half our range, yes. The least expensive chiller is $3,299, and 5 of our 10 chiller-less tubs cost less than that. Budgeting from the tub price is the single most common way people underestimate this purchase.

Can I buy the tub now and the chiller later?

Yes, and several of our tubs are built for it. The DCT Oval Barrel Tub at $2,299 ships without a motor so it can be run on ice and plumbed to a chiller afterwards. The chiller is the component that carries over to a future tub, so buying it second costs you nothing except the ice in the meantime.

Do the chillers also heat?

All 4 chillers we list are cold and heat units. They cool to 37°F and heat to 85°F, so one box covers a cold plunge and a warm soak in the same tub.
