Swimming pools are pools which are artificially constructed in different shapes and in different deeps for people’s swimming, fitness, playing with water, relaxation and so on. Swimming pool is the general appellation for competition pool, public pool, dedicated pool, private pool and relaxation pool.
A swimming pool, swimming bath, wading pool, paddling pool or simply a pool, is a container filled with water intended for swimming or water based recreation. There are many standard sizes, the largest of which is the Olympic-size swimming pool. A pool can be built either above or in the ground, and from material such as concrete (also know as gunite), metal, plastic or fiberglass.
