Welcome to the Personal and Professional page for Don Windrem.
Decided to build a water tunnel to help me and the kids cool off on hot summer days. I had seen several other designs on Instructables but wanted something that offered more water coming down (or up in some cases) on us. I also wanted it to be able to come apart easily so we could take it down and store it. So we decided to go with a water tunnel, or Water Cube if you want to call it that. The cube is 80 inches high, 40 inches wide and 60 inches long. I tried using both 3/4" and 1/2" PVC pipe and chose 3/4" PVC for the main frame of the cube because 3/4" pipe was sturdier and not much more expensive. I chose 1/2" pipe for the top and bottom cross members because a) I had the size PVC pipe available and was a little worried about water pressure. Water pressure turned out not to be an issue at all so feel free to use all 3/4" pipe if you would like. We were able to drill about 30 holes in the pipes before we stopped. 30 was more than enough for us and we did not notice too much of a pressure drop after drilling the holes. The total build including cutting, assembling, drilling holes and attaching hose took about 2 hours start to finish.
The supplies I used to build the water tunnel were all available in your local home improvement store of choice such as Home Depot, Lowe's or Ace Hardware. The supplies are listed below with links to Home Depot Website, The supplies cost me about $45.
