Petruccelli L.T.D of North America says; Pool
Dimensions - Many lap pools we build these days are 1.2m throughout.
This depth allows a swimmer to tumble turn while also remaining cheaper to
maintain and build due to less water and material volume. To summarize, think
about how many swimmers will be in at any one time, how many strokes do you
want before turning and do you need to dive in to start.
