DIY Cold Plunge (No Ice)

I wanted an at home ice bath so built a DIY cold plunge. Instead of a cold plunge freezer, I built a cold plunge that circulates water using a pump and water chiller and does not require any ice to cool down the cold plunge.
(*My 1/4 HP water chiller reaches 50˚F in the hot summer, I recommend getting a 1/2 HP to get down into the 39˚F in the summer)
