Introduction

The AS ColdPlunge 1 HP System is a complete turnkey cold plunge package that includes everything you need: a massive 216-gallon insulated tub, powerful 1 HP chiller, external filtration, circulation pump, and insulated hoses. This is the ultimate solution for serious cold plungers who want a professional-grade setup without piecing together components.

Design and Build Quality

The XXL insulated tub is built from durable reinforced PVC with double-wall construction for excellent thermal retention. At 72 inches long and 36 inches wide, it accommodates users up to 6'5" comfortably with full-body immersion. The 1 HP chiller is mounted externally with a high-flow circulation pump and external filtration.

Key Features

  • 216-Gallon XXL Tub: Massive capacity for full-body immersion with room to spare.
  • Double-Wall Insulation: Helps keep water cold between sessions.
  • 1 HP Chiller: Powerful enough to reach 37°F therapeutic temperatures quickly.
  • Complete System: Includes tub, chiller, pump, filter, hoses, lid — everything you need.

What to expect

We haven't tested this unit ourselves. This section is based on the manufacturer's published specs and general chiller sizing.

Cooling: AS ColdPlunge rates the 1 HP chiller (about 14,000 BTU/hr) down to 37°F. 216 gallons is a lot of water, so expect the first pull-down from tap temperature to take much longer than on a smaller tub. Once it is cold, the large thermal mass means the temperature swings less when you get in.

Insulation: The tub has double-wall insulation and a UV-resistant lid. Keeping the lid on and the tub out of direct sun cuts how often the chiller has to run, especially in hot weather.

Comfort: At 72" long and 36" wide, the tub is sized for tall users, with room for full-body immersion.

Filtration: An external 20-micron filter is included. How long the water stays clean depends on sanitizer, showering before use and keeping the lid on; see our water care guide.

Setup: It is a complete system, so there are no parts to match. You still need space for a tub that weighs roughly 1,800 lbs filled and a standard 110V outlet.

Verdict

The AS ColdPlunge 1 HP System earns our Best Complete Package rating for delivering everything you need in one purchase. The XXL 216-gallon tub is the largest in its price class, and the 1 HP chiller is rated down to 37°F. If you want a professional-grade cold plunge without researching components, this turnkey system delivers exceptional value.
