Built by Master Spas in Fort Wayne, Indiana, the Alpine Glacier brings hot-tub-industry construction to cold plunging: a 2.1 HP chiller, acrylic shell, all-weather cabinet, dual jets, and Wi-Fi app control, with two-person in-home delivery included. The 40°F minimum temperature is the warmest floor in its price class, and the 120-gallon fill makes water changes a bigger job than smaller plunges.

The Alpine Glacier is the mid-tier of Chilly GOAT's Alpine line, and its spec sheet reads like a compact spa: 84" x 42" x 30", 120-gallon fill, premium acrylic shell, walnut-colored all-weather cabinet, SoftTread non-slip flooring, LED lighting, two flow jets, and a topside control panel backed by Wi-Fi app control. The self-contained 2.1 HP chiller — the largest stated horsepower in this six-product group — covers a 40–104°F range, and a 24-hour circulation pump feeds a high-efficiency filter with UV light sanitation. It runs on a 120V/15A connection, and standard two-person in-home delivery is included in the contiguous US.
The residential warranty runs 2 years on the chiller, equipment, plumbing, and shell, with 1-year terms on the LED and UV systems — solid, though the factory-installed extras are covered for less time than the core. What the page does not state is a noise figure or any energy-use data, and the 40°F minimum means buyers chasing near-freezing water will need to look at ice-making designs instead. At 620 lbs dry, it is also a genuinely heavy unit that stays where it is delivered.
