Tripod and Enclosure

• 1). Drill a 3/4-inch hole in one end of each 10-foot-long two-by-four, 4 inches from one end.
  
  
• 2). Use a circular saw to cut the other end of each two-by-four to a point so this end will easily stab into the soil when the tripod is erected.
  
  
• 3). Put a flat washer on the 8-inch bolt, push the bolt through the holes in the two-by-fours, add another flat washer, then screw on the nut to loosely connect all three boards.
  
  
• 4). Cut a foot-long piece of 1/4-inch rope and use it to fasten the block pulley to the 8-inch bolt so it will suspend from the bolt when the tripod is erected.
  
  
• 5). Thread the remaining 15 feet of rope onto the block pulley.
  
  
• 6). Erect the tripod so the bottom of each leg is about 5 feet apart.
  
  
• 7). Wrap the tarp around the legs of the tripod if privacy is an issue.
  
  

Plumb the Bucket

• 1). Position the floor flange inside the bucket, against the side of the bucket with the edge of the flange against the bottom of the bucket and mark the position of the four 1/4-inch holes in the flange, as well as the center of the center threaded hole.
  
  
• 2). Drill the four quarter-inch holes, then drill the center hole using the 3/4-inch bit.
  
  
• 3). Apply a liberal coating of plumber's putty to the underside of the floor flange, then attach the flange securely to the inside of the bucket with the 1/4-by-1-inch bolts, using flat washers and nuts on the outside of the bucket. Wipe away any plumber's putty which oozes out around the edges of the flange.
  
  
• 4). Screw a 1/2-inch close nipple through the 3/4-inch hole in the bucket into the threads of the floor flange.
  
  
• 5). Screw a 1/2-inch ball valve onto the close nipple and then a shower head onto the other end of the ball valve.
  
  

Reflector

• 1). Cut the piece of plywood into two pieces, each one to be 20 inches by 30 inches.
  
  
• 2). Connect the plywood with a pair of hinges on the 30-inch sides.
  
  
• 3). Paint the plywood with white paint.
  
  

Operation

• 1). Check to make sure the ball valve is shut, then fill the bucket with water.
  
  
• 2). Set the bucket in a sunny place, put the lid on the bucket, then position the hinged plywood behind the bucket with the panels set to reflect the sunlight onto the sides and rear of the bucket.
  
  
• 3). Carry the bucket to the shower, tie the handle of the bucket to the 1/4-inch rope, then hoist it to a comfortable height by pulling the rope through the pulley. Tie the rope off to one of the tripod legs.
  
  
• 4). Turn the ball valve on and the shower will start running.
