Why Choose our Wood Fired Hot Tub?

  1. Premium Materials for Durability and Comfort
    • Crafted with Thermo-Spruce, a material that lasts twice as long as traditional cedar, the exterior is built to withstand harsh outdoor conditions.
    • The dark grey contoured fiberglass interior is designed for maximum comfort, ensuring a relaxing soak for every user.
  2. Efficient Wood-Burning Design
    • Equipped with a 304 stainless steel wood-burning heater featuring dual heat compartments, the Model S4B offers unmatched efficiency.
    • A self-cleaning corrugated stove reduces wood consumption by up to 50%, making it both eco-friendly and economical.
  3. Rapid Heating for Faster Enjoyment
    • Heats 304 gallons of water from 40°F to 95°F in just 1.5 to 2 hours—one of the fastest heating times available for wood-fired hot tubs.
    • The advanced heating system circulates water evenly for consistent temperatures throughout your soak.
  4. Fully Assembled and Ready to Use
    • The Model S4B arrives completely assembled, requiring no electricity or complicated installation. Simply set it up in your desired outdoor space, and you’re ready to enjoy a relaxing soak.
