Young Brunette Girl Outside In The Backyard At The Swimming Pool

Types
Private pools
Private pools are usually smaller than public pools, on average 12 × 24 ft (3.7 × 7.3 m) to 20 × 40 ft (6.1 × 12 m) whereas public pools usually start at 80 ft (24 m). Home pools can be permanently built-in, or be assembled above ground and disassembled after summer. Privately owned outdoor pools in backyards or gardens started to proliferate in the 1950s in regions with warm summer climates, particularly in the United States.
