When planning to install a pool, it is common to obsess over obvious factors such as placement, materials, and shape. Homeowners rarely think about the dimensions. It is important to determine if the pool will be predominantly used for swimming laps and exercise, or spending time with family and friends playing games and having fun. Lap pools are obviously purpose built to be long and narrow with a depth of 1.5m in order for swimming laps, plunge pools however can also accommodate lap swimming with the invention of the swim jet system or swim tether. These fantastic inventions enable you to swim an endless lap in your swimming pool either via swimming against a current of water or being held in position with the help of a tether system.
