The 10 Best Cold Plunge Tubs The Spruce Has Tested

The Nordic Wave Viking Cold Plunge Tub is our favorite thanks to its sleek, compact design. It's just 41 inches tall and 36 inches in diameter at its widest point. With a low profile and a small footprint, it can be placed nearly anywhere. Of course, as a vertical vessel, it's not made for stretching out but rather for submersion.

This cold plunge tub is made of foam-insulated thermoplastic and comes in your choice of charcoal, white, or blue. The robust insulation not only keeps your water reliably cold while minimizing energy costs but also eliminates condensation, which is ideal for indoor use. It comes with a powerful external chiller that promises to cool water quickly, and you can use the built-in thermostat to set it as low as 38 degrees.

The Viking also has multi-stage sanitation and filtration systems that keeps water debris- and germ-free. It comes with a step stool, an insulated lid, and a 10-foot power cord with circuit protection.

Though the price is a little steep at just shy of $6,000, Nordic Wave backs it with a five-year warranty. Thanks to their partnership with Peak Flow, a breathwork startup focused on delivering personalized breath training, you can also enjoy a free year of PRO access, which includes live breath and cold plunge sessions when you get a Viking tub.
