SaunaLife Model S4N Wood-Fired Hot Tub, Black Wood Finnish (6-Person)

Model S4N Outdoor Wood-Burning Hot Tub – The Fastest-Heating Wood-Burning Hot Tub Available offers an unparalleled combination of luxury, efficiency, and natural relaxation.

Designed to comfortably accommodate up to six people, this beautifully crafted hot tub enhances any backyard with its thermally enhanced spruce exterior, providing superior durability and weather resistance.

The ergonomically shaped fiberglass interior ensures maximum comfort while being easy to clean and maintain.

Built for efficiency, the Model S4N features an ingenious self-cleaning corrugated stove with a secondary heat chamber, allowing it to heat water up to three times faster than traditional wood-fired hot tubs.

This innovative design not only reduces heating time but also cuts wood consumption by up to 50%, making it an eco-friendly choice for those who appreciate sustainability. The air gap between the fiberglass lining and wood exterior further accelerates heating, while the natural convection system ensures even water temperature distribution.

With the ability to heat 304 gallons of water from 40°F to 95°F in just 1.5 to 2 hours, the Model S4N is the fastest-heating wood-burning hot tub available.

Plus, with no electricity required, you can create a true off-grid spa experience, embracing the simplicity of nature while indulging in total relaxation.

Whether you're unwinding solo or enjoying quality time with friends and family, the Model S4N Outdoor Wood-Burning Hot Tub from Sauna Nook is the perfect way to experience the benefits of traditional hot water therapy in a modern, high-performance design.
