A swimming pool, swimming bath, wading pool, or paddling pool is a container that is filled with water to enable swimming or other leisure activities. Pools can be sunk into the ground or built above ground, and are also a standard feature aboard ocean liners and cruise ships. In-ground pools are most commonly constructed from materials such as concrete, natural stone, metal, plastic or fiberglass, and can be of a custom size and shape or built to a standardized size, the largest of which is the Olympic-size swimming pool.
There are different types of pool but this are the basic types:
Private pools are usually smaller than public pools. Many countries now have strict pool fencing requirements for private swimming pools, which require pool areas to be isolated so that unauthorized children younger than six years cannot enter. Many countries require a similar level of protection for the children residing in or visiting the house, although many pool owners prefer the visual aspect of the pool in close proximity to their living areas, and will not provide this level of protection.
They are used mostly outdoors in yards, are typically shallow, and often their sides are inflated with air to stay rigid. When finished, the water and air can be let out and this type of pool can be folded up for convenient storage. They are regarded in the swimming pool as “splasher” pools intended for cooling off and amusing toddlers and children, not for swimming, but the alternate name of “kiddie” pools.
Public pools are often part of a larger leisure concern or recreational complex. These concerns often have more than one pool, such as an indoor heated pool, an outdoor pool which may be hot or cold , a shallower children’s pool, and a paddling pool for toddlers and infants.
