The crudest of DIY hot tubs is the backcountry tub. This involves filling some type of container with water and heat by dropping fire-warmed rocks into their depths. This method works well, but is labor intensive, not to mention that picking up and carrying smoking hot rocks has serious risks.

A more practical method involves flexible copper pipe, a campfire, some old garden hose, and the benefits of thermodynamics. This way the fire heats the water in the copper coil, and the warmer water moves upward through the system. This entire project can be done for under $300 depending on the container you use.
