Whether you have six months of hot weather or six weeks, a swimming pool is worth the investment. Although a pool may seem like a headache and never-ending maintenance, it doesn’t have to be. Interest in competitive swimming grew following World War I. Standards improved and training became essential. More than 50 years later, the home or residential swimming pool is a common sight.

An infinity pool is a swimming pool which produces a visual effect of water extending to the horizon, vanishing, or extending to "infinity". Often, the water appears to fall into an ocean, lake, bay, or other similar body of water. The illusion is most effective whenever there is a significant change in elevation, though having a natural body of water on the horizon is not a limiting factor. An Olympic-size swimming pool is a pool that meets FINA's additional standards for the Olympic Games and for world championship events. It must be 50 by 25 m wide, divided into eight lanes of 2.5 m (8.2 ft) each, plus two areas of 2.5 m (8.2 ft) at each side of the pool.

An oval model with slight wall reinforcements is also available, which could be better for those interested in swimming laps.
