The stock tank hot tub I built two years ago is still getting regular use most months out of the year. We've enhanced it to be more durable and to work as a small pool in the summer months by adding filtration. I haven't seen anyone else use these cheap and good quality parts on a stock-tank so wanted to share.

This revised design has several advantages:

- The smoke is pretty far away from the bathers.
- It durable and has stood up through 3 seasons so far.
- One person can move everything. The tank rolls easily once parts are removed. The only tool required is a large wrench to disconnect the coil.
- Filtration has worked well to keep the water clean. Many DIY examples on YouTube have filthy water.
- A 6 foot round tub is huge for a small family and fun to use as a kiddie pool.
- Heats fast (3-4 hours). You can cook on the fire while waiting. On a cool spring day, you can comfortably swim after an hour or so once the water hits the mid 80's.
- If you bought all of these parts new, you could build this for about $600. If you shop around you could build this for much less.
- I have an unlimited supply of wood on my lot. I only need to buy chlorine tabs and $5 filters every now and then. Monthly cost for electricity and supplies is under $10 for sure.
- It can be made with basic hand tools: a drill, saw, adjustable wrench, and a blow touch.

Certainly insulation or a more effective stove could improve this design, but that would add cost and sacrifice portability.
