"Fire Hot Tub" is a portable hot tub. The water used for the hot bath is injected with a hose, and firewood is used to boil the water, so there is no need for construction work such as water supply, gas, or electricity. The weight of the main body is 150 kg, which is lightweight for a hot tub, so you can carry it on a pickup truck and use it at a campsite.
To use the "Fire Hot Tube", inject at least 500 (maximum 800) liters of water and put firewood in a special basket. All you have to do is light the firewood and wait for the water to boil. The water in the bathtub passes through the pipe under the bathtub and into the metal coil that surrounds the wood basket. The water in the coil is warmed by the flame and rises. It is a mechanism that returns to the bathtub from the upper pipe and warms the water in the entire bathtub. After 2 hours, you can enjoy a hot tub with a water temperature of 37 degrees.
A windscreen is installed between the wood basket and the bathtub to protect the bather from flames. Users can also use the flames of firewood to barbecue. A small table and bottle holder are provided, so you can enjoy your meal while taking a hot bath.
In addition to orange, there are dark gray, olive green, light blue, black, white, pink, red, and yellow.
