Wood-Fired Hot Tub and Cold Plunge for 4–5 People

Create an outdoor wellness retreat with this pine wood-fired hot tub and cold plunge, designed for 4–5 people. Its dual-purpose design accommodates warm-water soaking or cold-water immersion, making it a versatile option for backyards, cabins, and off-grid retreats.

The round tub is heated by an external wood-burning stove constructed from 304 stainless steel. Because the heating system operates on wood rather than electricity, the tub can be used in locations without an electrical connection. For cold plunge sessions, fill the tub with cold water and add ice as needed.

Natural pine construction, an insulated cover, and included entry steps make this a practical addition to an outdoor wellness area. The included wooden paddle helps circulate the water manually, while the external stove provides access for adding wood and routine maintenance.

Installation and Use

Assembly is required. We will work with your contractor regarding installation requirements. Install the tub and wood-burning stove according to the manufacturer's instructions, including required clearances for the stove and chimney. Confirm the suitability of the supporting surface for the filled tub, which will weigh substantially more than the listed product weight.

Use the wood-fired heater only in an appropriate outdoor setting with proper ventilation and fire clearances. Follow the manufacturer's guidance for water temperature, operation, cleaning, and water maintenance. The supplier's estimated two-hour heating time may vary with starting water temperature, weather, and fire conditions.
