All the water in the Hot Plunge will pass through the filter 5+ times/hour keeping it fresh.

The Hot Plunge uses a standard 110v outlet, and it can pull up to 9 amps at a time. Therefore, we strongly recommend a dedicated breaker.

Your Hot Plunge assembles in 10 minutes with no tools or plumbing required.

With its 2” thick walls, polyurethane injected interior, and hard lid, Hot plunge’s
insulation sets it apart from the competition. This insulation makes for fast cooling, less

Will I fit in the Hot Plunge?

This is our friend Scott who is 6’7” 260lbs. He fits comfortably in the cooler, and he is an avid cold plunger. If he can fit, we believe most anyone can fit!


Yes, but if outside we recommend putting it under a covered area like a patio, umbrella, or under a deck to protect it from the elements.

104 degrees

There are two different components to keeping the water clean: filtration and sanitation. For filtration, you need to keep your filter cartridges fresh so they do not get clogged and prevent flow. Depending on usage, you typically need to change your filter cartridge every 2-4 weeks.

For sanitation, we recommend purchasing our Sirona chemicals, and following our sanitation guidelines. If you follow these guidelines and change the filters appropriately, your water can stay clean for 3+ months.

The Hot Plunge uses about 115 kwh to maintain the 104 degree temperature.

We offer a 1-year warranty on the Hot Plunge. To read the full details of our warranty, click here.

The Hot Plunge will be delivered via LTL freight on a pallet. Once it is picked up from our facility in Texas, the freight carrier will call, text, and/or email you to schedule the delivery appointment. They will drop the pallet off curbside at your house, and it is your responsibility to move it into place and dispose of the packaging.

Included with your Hot Plunge is an instruction manual on how to put it together as well as a QR code to a video showing how to assemble. It is best to set up with at least two people, and it should take about 15 minutes to put together. The only tools required are a box cutter or scissors to cut away the packaging.
