Back in the 1960′s wood fired hot tubs began to emerge in all sorts of alternative communities. Using not much more than firewood, outdoor hot tubs were able to get hot enough for an outdoor midnight lounge session even in the snow. An innovative design has recently emerged that works much like the wooden barrel wood fired hot tub but with all of the modern day bells and whistles.

Using the laws of physics, the FireHotTub circulates cold water through its advanced coil system. The hot tub's water is heated by a wood burning fire. The lightweight and portable frame allows you to take it everywhere? Parties and even secluded wilderness adventures! As long as you have a minimum of 130 gallons of cold water available, this may work is you have access to a clean stream?

How does it work?

130 gallons of water to start water circulation holds a maximum of 220 gallons capable of heating 100 degrees in about 2 hours the water is pushed through the metal coils which surround a wire basket where the firewood is housed the basket is raised or lowered to adjust the water's temperature

Bonus: There is a ledge to hold drinks and you can grill or toast marshmallows for a round of hot tub smores while you soak!
