Hot Tub - SaunaLife S4B
Fits 6 People
Units Sold This Month
The Model S4B wood-fired hot tub arrives completely assembled and is easy to set up. Its ergonomically shaped fiberglass tub is a comfortable place for up to 6 people. The interior surface is easy to clean, and the exterior is crafted from thermally enhanced spruce for superior weather resistance and durability.
Engineered for efficiency and performance
Engineered and crafted in the Northers Europe, this super-efficient hot tub heats in 1/3 of the time as traditional wood-fired hot tubs. No electrical connection is required. At the heart of the Model S4 is its ingenious self-cleaning corrugated stove with a secondary chamber that transfers heat from the smoke – reducing wood consumption up to 50% compared with other hot tubs. Brilliantly, the air between the fiberglass lining and the wood exterior is super-heated to accelerate the heating process. The stove is cleverly engineered to draw cooler water through a lower channel and redistribute it though an upper channel to equalize the temperature.
Start enjoying sooner
This incredibly efficient wood stove will heat 304 gallons of water from 40°F (5°C) to 95°F (35°C) in 1.5 to 2 hours – the fastest-heating wood-burning hot tub available.
Relax with friends and family the luxury of your Model S4 backyard wood-burning hot tub from SaunaLife.
