DIY Wood Fired Hot Tub Steps:

  1. Make two footings for the tub on top of some packed gravel. Forms the concrete mix out of crap melamine. Let them dry. Add few bags of gravels and sand on top of the footings to bury them.
  2. Make the heating coil by the copper tubing. Wrapped the copper tubing around the bucket, make the coil to be about 18 inches tall from top to bottom.
  3. Make the braces for the coil from the steel bars. Mark the locations on the steel bars for the bolt and drilled a series of holes. Bolted the steel bars around the copper coil.
  4. Make the through-wall fitting. Drill one and three-eights inch diameter holes on the stock tank 18 inches apart. Thread the tank fittings through the holes. Use silicone to seal the fittings.
  5. Screw in some compression fittings to connect the tub with the coil.
  6. Insert the end of the copper (which has been trimmed) to the compression fittings.
  7. Pounded the steel bars into the ground.
  8. Make the hot tub cover. Screwed together the wood bars. Cut the underside into curvy line.

With two big armfuls of firewood, 56 degrees F water, and 63 degrees F ambient temperature, it takes about two hours to get 110 degrees F hot water. You can add second copper foil or larger diameter copper tubing to speed up the temperature rise.

Beautify the tub by building a wood enclosure, so you will feel more incredible relaxing sensation. This easy to assemble hot tub is really worth a try. You can have relaxing time anytime you want in your backyard. If you want to spend the spas time with some friends or family, you can purchase larger galvanized steel tank available in the market.
