The Cedar Barrel Cold Plunge
The Cedar Barrel Cold Plunge brings the classic shape of a wooden tub to your sauna routine. It's 42 inches across and 39.5 inches tall, with a built-in seat inside and a Pacific cedar step outside, so getting in and settling down feels natural.
Choose what's inside: a PVC insert, valued for how well it insulates, or polished 304 stainless steel. Then choose the outside — natural cedar or black. Either way, it looks at home beside a sauna on the patio or in a home gym.
Come out of the heat, sit down into the cold, breathe slowly and let the shock turn into calm. Add a Dynamic chiller and the water holds the temperature you choose, from 37°F to 85°F, set on the touch screen or from your phone — filtered and ozone-sanitized while you're away.
A custom cover with child-safety latches keeps it closed between plunges. Buy the tub alone, or as a set with a 0.8 HP or 1.0 HP chiller.

Before you buy
Where it can go
Where it can go
- Indoors or outdoors, on a flat, stable surface that can carry the full tub plus a person.
- Indoors: a waterproof floor, ideally near a floor drain — water can spill when filling and draining. Not on carpet, and in a well-ventilated room.
- Outdoors: smooth ground free of sharp stones and branches, with the included floor mat underneath; avoid long hours of direct sun.
- Plan easy access to a water source and drainage.
The chiller
The chiller
- Cools to as low as 37°F and heats to 85°F, set on a splash-proof touch screen or from the Wi-Fi app (Tuya Smart).
- Built-in self-priming circulation pump, two-stage filtration with 20-micron replaceable filters, and automated ozone sanitation.
- Runs on a standard 120V outlet, with GFCI protection built in; rated for indoor and covered outdoor use.
- A chiller isn't included with the tub-only options.
Water and care
Water and care
- Fill to about 70% so your head stays well above the water line; start with less and add as needed.
- Keep the pH between 7.2 and 7.8 and test the water regularly; the optional chiller filters and ozonates the water.
- Clean the inside with a soft cloth and a neutral detergent — no hard-bristle brushes.
- For storage, drain completely, wipe dry, cover, and keep it above freezing and out of prolonged sun.
Warranty and safety
Warranty and safety
- Dynamic Cold Therapy warranty: 1 year on the insert, the wooden shell and trim, and all other tub components. The chiller has its own 1-year warranty.
- Check with your doctor before starting cold plunges, especially with heart disease, high or low blood pressure, circulation problems, diabetes or if you take medication.
- Immersion in water below 70°F carries a risk of hypothermia, and body temperature can keep dropping after you get out. Enter feet first, breathe steadily, and never plunge after alcohol or drugs.
- Never leave children unsupervised near the tub; lock the cover with its clasps when it's not in use.
