In hot summers, all you desire is a swimming pool in the backyard of your house. You can have two types – in-ground and above ground pools. The concept of having an above-ground swimming pool started in early 1930s. Back then, only the rich could afford a pool in the backyard, but today, you dream it and you have it. Every year some new change comes up with either the design or the technology used – making the product even better.
