Base

A level, solid base that can carry the weight (365 lbs): a concrete pad, pavers, or a framed deck checked for the load.

Permits

Some cities and HOAs regulate burning and backyard structures. Check with yours first.

Install notes

Most residential plunges and chillers here run on a standard 110 to 120V outlet. Use a GFCI protected receptacle, avoid extension cords, and give the chiller the ventilation clearance the maker lists so it can shed heat.

A filled plunge is heavy, often 800 to 1,500 pounds. Indoors, put it on a slab or a floor an engineer has checked; outdoors, use a level pad and plan drainage for water changes.

Not included. Plan for these.

About this cold plunge

The Renu Therapy Cold Stoic 3.0 Cold Plunge is a complete cold plunge holding about 95 gallons, with a temperature range of 37°F to 104°F. The maker prices it from $12,799 to $13,499.

A purpose-built plunge is mostly about insulation and water care. A well insulated tub with a lid holds temperature on a small chiller, and good filtration means fewer full water changes.

Sound: 58 dB from ~3 ft
Weight empty: 365 lbs
Filled weight: 1,155 lbs
