Can a DIY build a small in-ground swimming pool?
I would not recommend an in ground pool as a DIY project, unless you are looking for a sure fire life time maintainence project. Even installing a fiberglass shell is not as simple as it appears. If you really want a pool, I'd save for a couple of years and get a reputable builder to install one. Get the pool plumbed with QUALITY equipment, not bottom end stuff, and save the fancy decking for later , when money is available. The fancy decks will look a lot more enticing in the sales portfolio than buying higher priced equipment, but remember that you will expect this stuff to run for 10 to 14 hours per day, seven days a week, for many years.
