[…] [page 126] [O]ne of the best ways to reform an unruly gang is to get them to be devoted to a vigorous, manly man. There seems to be very little of this spirit in the present natatoriums. This is due in part to the swarms in which the boys come to the pool whenever it is open to them.
** 1949, Griffenhagen & Associates, City of Milwaukee Report, [Chicago, Ill.], →OCLC, page 10:Although the public does not pay an admission fee for the privilege of using natatoria facilities, the city charges ten cents for towels and soap, and ten cents for the rental of swimming trunks and bathing suits. In 1948 total revenues were $20,284 from this source for all natatoria.

An outdoor, oceanside pool was envisioned as part of the Waikiki War Memorial Park, which honored Hawaii's soldiers killed in World War I. […] In 1927 the facility opened and became known as the Waikiki Natatorium. The 40 × 110-yard Natatorium was the world's largest open-ocean swim stadium.

    A sunken chamber almost like a natatorium at some hot-springs resort, so cool and dim that you forgot after a while about the desert waiting out there to resume for you as soon as you stepped back into it. […]
** 2009, National Intramural-Recreational Sports Association, Campus Recreational Sports Facilities: Planning, Design, and Construction Guidelines, Champaign, Ill.: Human Kinetics, →ISBN, page 58:Natatoria are often programmed as part of Rec centers. Like gymnasiums, natatoria may be of many different sizes, but they require large clear-span structures. In addition, swimming pools have specific requirements for soil conditions and foundation systems, as well as spatial relationships with equipment rooms and locker rooms. […] These unique features make it very unlikely that an existing building can be transformed into a natatorium for less cost than building new. If the other desired program elements can be adequately developed within existing space, the natatorium piece might be a sensible addition or future phase.
