Effortless Cold · Year-Round
Plunge Every Day, Without the Ice
A powerful ¾ HP chiller that keeps your cold plunge cold — quietly, efficiently, all year long.
Penguin Cold-Therapy Chiller with Filter Kit
Overview
The Penguin Cold-Therapy Chiller keeps your cold plunge cold — effortlessly. A powerful ¾ HP high-efficiency system holds your water in the low-40°F range without hauling a single bag of ice, so you actually plunge consistently.
At just 56 dBA it's quiet enough for indoor use yet rugged enough for year-round outdoor installation, and runs for about $18–$28/month in electricity. The built-in pump circulates water continuously through the included filter kit, naturally suppressing bacteria and extending water life.

Effortless Cold
Consistency Is the Whole Point
Cold therapy only works if you actually do it — and nobody plunges for long when every session starts with dragging ice from the freezer. The Penguin keeps your water in the low 40s automatically, quietly, day and night, for the price of a couple of coffees a month. The pump and filter kit keep it clean so it's always inviting. Set it up beside any plunge tub and the cold becomes a habit instead of a chore.

My S1B sits just outside the studio and the Penguin runs quietly enough that it never bothers me or the neighbors. Cold is steady and the filter keeps things clean. Sauna Co. shipped the chiller with the tub and recommended the pairing with real taste.
Give it airflow and a nearby outlet and it performs beautifully. The filtration is excellent. Support advised on placement and shipped fast.
Paired with my insulated Baltic tub, the Penguin chiller locks in 48°F and barely cycles thanks to the tub's insulation. The included filter kit keeps the water crystal clear between changes. Sauna Co. shipped it with the plunge and the rep understood athletic recovery cold-water needs. Flawless for daily training.
Dial in the cold and it just holds, day after day. The filter kit is a genuine bonus for water clarity. Delivery was prompt and well-packed.
