AS ColdPlunge 1 HP System Review: Complete Setup

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: Excellent thermal retention keeps water cold for 24+ hours.
• 1 HP Chiller: Powerful enough to reach 37°F therapeutic temperatures quickly.
• Complete System: Includes tub, chiller, pump, filter, hoses, lid — everything you need.

Performance

We tested the AS ColdPlunge 1 HP System over 8 weeks with daily use in various weather conditions.

Cooling Speed: On the full 216 gallons from 72°F, the 1 HP chiller reached 42°F in approximately 6 hours and 37°F overnight. The large thermal mass actually helps stabilize temperature once cold.

Temperature Stability: Once at target, this system maintains within ±1°F. The large water volume and double-wall insulation mean the chiller cycles infrequently, extending compressor life.

Comfort: The 72" length accommodates tall users (6'5"+) with full submersion up to the neck. The 36" width allows comfortable positioning without feeling cramped.

Insulation Performance: In 85°F ambient heat with the lid on, the water temperature rose less than 3°F over 24 hours — excellent thermal retention that reduces energy costs.

Filtration: The external 20-micron filter keeps the large water volume crystal clear. We went 4-5 weeks between water changes with minimal chemical treatment.

Setup: The complete system arrives with clear instructions. Setup takes 2-3 hours for initial placement, plumbing, and electrical connection.

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 powerful 1 HP chiller maintains therapeutic temperatures effortlessly. If you want a professional-grade cold plunge without researching components, this turnkey system delivers exceptional value.
