What Comes With a Cold Plunge? What's Included

A cold plunge purchase usually includes the tub, an insulated lid, and the water care parts you need to run it. On many complete systems the chiller comes in the box. On budget and inflatable tubs it does not. Here is exactly what to expect in the package, and what most buyers still have to add.

The short answer

What comes with a cold plunge depends on whether you buy a complete system or a stand alone tub. A complete system typically ships with the tub, a fitted insulated cover, a chiller that cools (and often heats) the water, a circulation pump, a filter, and a sanitation method such as ozone or UV. Many also add insulated hoses, a spare filter, and a repair kit. A budget or inflatable tub often includes only the tub, a cover, and a simple hand pump, with the chiller sold as a separate purchase. Steps, extra filters, a water treatment kit, and a base pad are common add ons at every tier. Because the term cold plunge covers everything from a small inflatable to a built in unit that costs several thousand dollars, read the product page line by line and confirm the chiller is included before you check out.

What is usually included with a cold plunge

Most cold plunge listings bundle the core parts you need to fill, chill, and keep the water clean. On a complete system you can generally expect:

• The tub or basin. Hard sided acrylic, stainless steel, a rotomolded shell, or a reinforced inflatable body.
• An insulated cover. A fitted lid that holds the cold in and keeps debris out. This is standard on almost every tier.
• A chiller (on complete systems). The unit that pulls water temperature down to roughly 39 to 55 degrees Fahrenheit. Many combine cooling and heating in one box.
• A circulation pump. Moves water through the chiller and filter so the whole tub stays evenly cold.
• Filtration. A cartridge filter, often rated around 20 to 50 microns, that traps skin, oils, and grit.
• Sanitation. An ozone or UV system on premium models that keeps the water clear between changes.
• Hoses and fittings. Insulated lines that connect the tub to the chiller, plus the couplers you need to run them.

Is the chiller included or sold separately?

This is the single most important thing to verify, because a chiller is the most expensive part of the setup. On complete plunge systems the chiller is bundled and the price reflects it. On many budget tubs and inflatables, the listing price covers only the tub and cover, and the chiller is a separate line item that can add a large amount to your total. Some brands also sell the same tub in two versions, one with the chiller and one without, so two listings that look identical can be priced very differently. If the product page does not clearly say the chiller is in the box, treat it as an add on and ask before you order. Our guide to choosing a cold plunge chiller walks through sizing and what the numbers mean.

What is often sold separately

Even on a well equipped system, a few items usually cost extra. Budgeting for these up front keeps the real price honest:

• Steps or an entry stool for tubs with tall walls.
• Extra cartridge filters and a water treatment or sanitizer kit for ongoing care.
• A base pad or level foundation if you are placing the tub outdoors or on soft ground.
• A weather cover or shelter for outdoor installs in sun, snow, or freezing conditions.
• An upgraded chiller if the included unit is undersized for a hot climate or a large tub.

Questions to ask before you buy

• Is the chiller included, and what is its horsepower or cooling rate?
• Does the chiller also heat, so you can run contrast sessions or warm the water in winter?
• What sanitation is included, ozone, UV, or none?
• How many filters ship in the box, and what do replacements cost?
• Are hoses, fittings, and a cover all included, or priced separately?
• What does the warranty cover on the tub versus the chiller? Our warranty and support page explains what to look for.

Buying from an authorized retailer means the manufacturer warranty stays valid and you get real support if a part arrives damaged. Free US shipping and HSA or FSA eligibility apply on qualifying recovery equipment, and financing is available so you can spread the cost.

A quick safety note

Cold water immersion is not right for everyone. According to Cleveland Clinic, sudden cold exposure can raise blood pressure and heart rate, and people with heart conditions should be cautious. Start with short sessions, never plunge alone until you know how your body responds, and talk with your doctor first if you have a heart condition, high blood pressure, or are pregnant.

Frequently asked questions

Does a cold plunge come with a chiller?

Sometimes. Complete cold plunge systems usually include the chiller in the price. Budget tubs and inflatables often sell the chiller separately, so confirm it is in the box before you order, because the chiller is the most expensive part of the setup.

What do you need to run a cold plunge that is not included?

Common extras are steps, replacement filters, a water treatment kit, and a level base pad for outdoor placement. On tubs sold without a chiller you also need a chiller and a pump, which are the biggest added costs.

Do cold plunges come with filtration and sanitation?

Premium systems typically include a pump, a cartridge filter, and ozone or UV sanitation. Simple inflatable tubs may include only a basic cover and hand pump, so you would add your own filtration and water care.
