Penguin Chiller vs Hydragun Supertub
The Penguin Chiller is the cheapest way to get real refrigeration if you are comfortable supplying a tub and doing the setup, but it scores lower because it has no tub, no water care, and is not freeze-proof. The Hydragun Supertub is the cheapest complete, self-chilling plunge with water care built in.
These are two routes to chilled water. The Penguin Chiller is a chiller only: you supply the tub and plumb it in, for the lowest hardware cost. The Hydragun Supertub is a complete all-in-one with tub, chiller, ozone, and filtration.

FAQ
- Why does the chiller-only unit score lower?
- Our scoring rewards a complete, usable plunge. The Penguin Chiller has no tub, no ozone or filtration, and the maker warns it is not freeze-proof, so it loses points the all-in-one Hydragun earns.
