Cold Plunge FAQs

A chiller cools the water and holds it at the temperature you set, so there's no need for bags of ice. Many chillers can warm the water too.

Some of our plunges come with a chiller included, while others are sold as the tub on its own, with chillers available separately. Each product page lists exactly what's in the box.

Most of our chillers take the water down to the mid-to-high 30s °F. Many can warm it too, and some go well past 100°F, so one tub doubles as a hot plunge.

Cooling takes a little time, typically a few degrees every half hour or so, so it's worth setting your temperature ahead of your session. The exact range for each model is in its specifications.

Match the chiller to the amount of water in your tub. Each chiller lists the largest tub it can handle in gallons, and a more powerful chiller (a higher HP rating) cools the water faster. Not sure which fits your tub? Email us and we'll check.

There's no single right answer. Many people start with cooler rather than icy water and short dips, then build up as they get used to it.

If you have a heart condition, high blood pressure or any other health concern, check with your doctor before you start.

Many of our chillers plug into a standard 120V household outlet and have a built-in GFCI safety switch, so there's no need for an electrician. The exact requirement for each model is listed in its specifications.

Plug straight into the wall where you can. If you need an extension cord, check the manual for what's suitable.

Indoors or out, as long as the surface is level and strong enough. Once filled, a plunge is heavier than you might expect: most weigh around 700–900 lbs, and larger models can reach 1,600 lbs or more. Each product page lists the filled weight, so if it's going indoors, it's worth checking your floor can take it.

Outdoors, keep the chiller somewhere covered and out of direct rain, and keep the lid on when you're not plunging to protect the water from sun, debris and freezing weather. Each product page confirms whether a model is suited to indoor or outdoor use.

It depends on filtration. With the chiller's filter running, a sanitizer if your model has one, and the lid on between sessions, many owners go a few months between water changes. Without filtration, plan to drain and refill much more often. Your manual has the manufacturer's recommendation.

Larger plunges travel by freight truck and are delivered curbside. The driver uses a liftgate to set the crate down at the end of your driveway; they can't bring it inside. The carrier calls 24–48 hours ahead to book a delivery window, and an adult needs to be there to sign. Smaller items, like chillers and inflatable plunges, may arrive by regular ground delivery instead.

Before you sign, check the packaging. If you see any damage, write it on the delivery receipt, take photos and email us within 48 hours. Full shipping and delivery policy
