Product Highlights
ThermoWood® Construction
The tub body is crafted from ThermoWood®, a heat-treated timber that offers superior resistance to moisture, warping, and decay compared to untreated wood — built to last through changing weather conditions.
Fiberglass Interior
A seamless fiberglass liner keeps water clean and makes routine cleaning straightforward. It resists staining and is gentle to the touch during use.
Integrated Side-Fired Wood Heater
The built-in wood-burning heater is positioned on the side of the tub for space efficiency. It brings water to bathing temperature in approximately 90 minutes under typical conditions.
4-Person Capacity
With a 5'11" diameter and roughly 395-gallon water capacity, there is ample room for up to four adults to soak comfortably at the same time.
Optional Upgrades
Customize your setup with optional LED lighting or hydrotherapy jets to tailor the experience to your preference.
Fully Assembled Delivery
This hot tub ships fully assembled, reducing installation time and effort so you can focus on setup rather than construction.
