Just the old fashioned way, tub of cold water and a 20lb bag of ice 🤷‍♂️

Might build one, but might not 🤷‍♂️😂

i guess even the bathtub works with the bag of ice. it's not as fun when it's not outdoors tho

It all depends on how badly you want to cold plunge. I have bad injury history so it helps with inflammation and wicked sore joints and pain. Not too much tho bc also need that natural inflammation to help recover and build more muscle/etc
