Abstract
Abstract The disclosure relates to a swimming pool which is prefabricated and is assembled on site from the component parts. The shell of the pool containing the water during use is formed from a flexible inner liner which is attached to the sides of the pool. The construction also includes a one-piece coping which is placed around the deck of the pool and at the inner edge thereof in order to give the pool a rectilinear appearance despite the bowing caused by outward pressure exerted on the pool walls by the water within the pool.
