Cold plunge pool systems and methods

1 . A cold plunge system, the system comprising a reservoir having an inlet and an outlet, wherein the inlet and outlet are connected to an external sequential plumbing system having a filter and a thermodynamic regulator device connected via an insulated pipe system.

2 . The cold plunge system of claim 1 wherein the thermodynamic regulator is compressor based with an evaporator and a condenser.

3 . The cold plunge system of claim 1 further comprising a control panel with processor and operably configured software.

4 . The cold plunge system of claim 1 wherein the insulated pipe system comprises a configuration of five pipes connected via ports and joints.

5 . A method of maintaining liquid temperature of a cold plunge pool, the method steps comprising:

obtaining a reservoir,

connecting a first pipe to a reservoir outlet,

connecting a filter inlet to a first pipe, connecting a second pipe to a filter outlet,

connecting a thermodynamic regulator inlet to the second pipe,

connecting a third pipe to the thermodynamic regulator outlet,

connecting a first joint to the third pipe, connecting a fourth pipe to the first joint,

connecting a second joint to the fourth pipe, connecting a fifth pipe to the second joint,

connecting the fifth pipe to a reservoir inlet,

filling a reservoir with a liquid, and

initiating a pump to circulate the reservoir liquid through the cold plunge pool system at a substantially constant temperature.
