Brief History of Paddling Pools / Pools
The pool is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground; in-ground pools; or built above ground,as a freestanding construction or as part of a building or other larger structure. In the early 1800′s, in Britain, the National Swimming Society introduced the first competitive swimming. Most pools are permanent fixtures, while others are temporary, collapsible structures. Pools can be either indoors or outdoors, they can be of any size and shape, and inground or above ground. Kiddie pools are regarded in the swimming pool industry as "splasher" pools intended for cooling off and amusing toddlers and children, not for swimming. Temporary polyvinyl chloride pools are used mostly outdoors in yards, are usually shallow, and often their sides are inflated with air to stay rigid. Afterwards it's easily taken down and folded up for convenient storage.
