I used to swim a lot before i moved to Richmond and was looking for another way to get in shape, without wasting time going and coming back from a gym when i have my gym in my basement. So, In popped the idea of having my own pool...but my backyard is so small? I figured I'd dig a hole, some cinder blocks, plaster, and attach myself by a harness to the garage wall. Well it turned into a bigger project with a 4hp pump to make it endless with no harness. On top of that, by the time I was done building it, getting in shape by swimming in it wasn't as pertinent lol! some people have asked about price... i did it myself to not incur cost :) I salvaged as much as I could...so your costs depend on whether you enjoy the hunt of a deal or if you just go and buy things....
