  • Push-To-Connect Fittings
  • Through Wall Pipe Fitting
  • Copper Tubing

  • Shovel


Step 1

Place the stock tank in the area where you want it to be, then trace the tank around, set it aside, and start digging about 8 inches into the ground along the traced shape. Pour about 2-3 inches high of gravel into the dug area, then using scraps of melamine, build 5½-inch thick frames for the 2 slabs, and pour the concrete mix into the inside of each frame. Pour some more gravel, then pour sand over them, and spread and pack them nicely so they are smooth and level.

Step 2

Cut a ½-inch copper tubing into 20 feet long, then bend it around a 5-gallon bucket into a coil shape, and then cut 1x¼-inch steel bars for the support of the coil. Drill holes in the bars, then bolt them together with the copper tubing and start drilling holes onto the stock tank about 1 and 3/8 inches in diameter making sure they are 18 inches apart from each other. Now, add the fittings, then plug in the copper, and secure the coil in place. Using ¾ inch redwood, build a lid to fit the top of the tank, then test the heat of the tub, and you’re done.
