Morozko's entry residential Forge is one of the few plunges that reaches 32°F and can be configured for ice-making, with chlorine-free ozone sanitation, microfiltration, and a winter circuit rated to -10°F ambient. The 1-year non-transferable warranty is the shortest in its price class, and the page publishes no water volume, chiller horsepower, or weight figures.

The Forge is Morozko's lightest and smallest residential ice bath, hand-built to order in Phoenix, Arizona with roughly five weeks of lead time. Its stainless-steel tub is wrapped in a durable polyurea coating for outdoor installation, comes in charcoal or white and two lengths (79" or 85" overall, 28-3/4" wide, 26-3/8" tall), and its digital controller can hold any setpoint down to 32°F — even in ambient heat above 110°F — or be configured for what Morozko calls massive ice making. Water care is chlorine-free: microfiltration with an inlet strainer, ozone disinfection, no added chemicals, and no routine water changes claimed, with the filter cartridge serviced about every hundred plunges. Power is a standard 110V three-prong cord with inline GFCI, and a separate warming circuit protects the pump and piping down to -10°F outdoors. Morozko also claims it is the quietest off-the-shelf ice bath available, though no decibel figure is published.
The spec sheet leaves real gaps: no stated water volume, chiller horsepower, BTU rating, or empty weight, so paper comparisons against rivals lean heavily on the 32°F capability. The warranty is 1 year, non-transferable and non-relocatable without permission — notably shorter than the 2- and 3-year coverage common at this price — and the mechanical compartment must be installed under a roof and protected from water intrusion, with damage from improper siting excluded. It is also designed around a daily-use envelope of up to 60 minutes of plunge time while maintaining ice.
