Would it be too costly just to buy the shell of a fibre glass swimming pool? You know like one where you have installed in a hole in a ground, but instead of that, you just buy the pool and tote it around on the back of a truck?

Or a really big inflatable pool like this? Scroll down to 2nd pic, that seems deep enough?
