Here in Texas our ground water come out of the tap at 68 F in the summertime. My wife asked for a “cold shower” button because she didn’t want to take up the space in our house with a cold plunge, but she read it helps with weight loss and depression. So I combined this with a beverage cooler, an aquarium chiller, an air switch and some aquarium pumps for instant cold shower. I wrapped this in pipe wrap insulation to keep cold losses down. Works great!
