Cold Plunge Chillers

Cold plunge chillers and ice bath chillers that cool, circulate and filter the water and hold it at your set temperature. No more buying bags of ice.

What a cold plunge chiller does

A chiller is a small refrigeration unit with a pump. It draws water from your tub, cools and filters it, and returns it, holding the temperature you set. With a chiller the tub stays cold between sessions and the water stays cleaner.

What to compare

  • Cooling power: listed in horsepower (HP). Check the tub volume each chiller is rated for and match it to your tub.
  • Lowest temperature: listed per model. Look at how cold it can go and how long it takes to get there.
  • Filtration: an external or built-in filter keeps hair and debris out of the water.
  • Controls: some chillers have Wi-Fi app control and timers.

Setup tips

  • Use a chiller-compatible tub with inlet and outlet ports, or one the chiller hoses can reach.
  • Give the chiller airflow on all sides and keep it out of standing water.
  • Plug it into a properly rated outdoor outlet with GFCI protection, and keep the tub covered to save energy.

Cold Plunge Chillers FAQ

Do I need a chiller for a cold plunge?
No. You can cool a tub with ice. Use our ice bath calculator to see how much you need. A chiller removes the ice runs and holds a steady temperature, and its filter keeps the water cleaner for longer.
What size cold plunge chiller do I need?
Each chiller lists the tub volume it is rated for. Find your tub volume in gallons or litres and choose a chiller rated for at least that much water.
Where should a cold plunge chiller go?
On a level surface next to the tub, with clear airflow around it, out of standing water, and plugged into a GFCI-protected outlet suitable for its power draw.
