Dundalk Polar Plunge Tub

Both perform the same. The White HDPE plastic liner is durable, lightweight, and the standard option. The 304 stainless steel interior is non-porous and commercial grade, the same material used in cold-therapy clinics, for a brighter look and the easiest cleaning. Stainless is the upgrade; plastic is the value choice.

No. The tub ships without a chiller so you can pick the right one for your climate. It is compatible with the Penguin Cold Therapy Chiller with Filter Kit and the Coldture Water Chiller Pro, both available as add-ons. Text us at (608) 909-8117 to add one.

With a compatible chiller the Polar holds water in the high 30s to low 40s Fahrenheit, even in full sun. Without a chiller you run it as an ice bath.

No. You fill it from a garden hose and empty it through the built-in floor drain with a standard 3/4 inch hose connection. A chiller plugs into a normal 110-120V GFCI outlet.

It is a one-person tub. The exterior is 71 by 33 by 25 inches with a 190 gallon capacity and angled sides for easy entry.

Yes. The tub arrives fully built, with the cedar, bands, and liner already assembled at the factory. The only setup is threading on the supplied drain hardware, a few minutes with an adjustable wrench, then you place it, fill from a garden hose, and plunge. If you add a chiller, it connects to the pre-drilled ports.

Yes. The cedar exterior weathers fine outdoors. In freezing conditions, drain the tub and disconnect the chiller to protect the equipment, then refill in spring.

You may be able to. It depends on your plan and your situation. Because a cold plunge can be used for both general wellness and medical treatment, HSA and FSA rules generally treat it as a medical expense only when a licensed provider gives you a Letter of Medical Necessity (LMN) tying it to a specific diagnosed health condition. A letter is usually required but does not by itself guarantee eligibility. You can get one from your own doctor or a telehealth service, so you are not locked into TrueMed. On payment: many HSA and FSA debit cards only work at health-coded merchants, so they are often declined at a general store like ours. The most reliable route is to pay with a regular card, save your itemized receipt and LMN, and request reimbursement from your plan administrator. Confirm coverage and how to file before you buy, since each plan sets its own rules. We cannot give tax or legal advice, but we are glad to help with the order. Text (608) 909-8117.
