Having a pool in the backyard is always a cool thing to have in the summer. If you live in a small neighborhood, though, you may have to settle for having one of those miniature pools. But these are ideal if you have small children, because water that is less deep is always a plus. Sure, you don’t exactly get to swim, but in the summertime I’m fairly certain you’re more than a little desperate to keep cool, right? But, if you don’t have kids, then you can have it with a larger pool, but remember your water bill will go up drastically with a larger pool (unless you manage to beat the system).
