Natatorium

A natatorium is the area of a ship or station that houses a swimming pool and accompanying locker rooms, showers, and sauna areas. These areas were first installed on the Ambassador class of ships as an additional source of recreation for long-term missions. While crews value and appreciate having them, they have fallen out of favor by ship designers and admirals alike due to operational costs, upkeep, and the amount of precious interior space they take up. Instead, newer ships have pre-installed programs on their Holodecks that cover a wide range of water-borne activities. Natatoriums can still be found on some stations and almost all Federation colonies and planet-based facilities have them.
