48 inches
Hi Mary - The best source for info is the Official source - OceanLakes.com. The required height is NOT 46 in. it is 48 inches for the big slides, and 36 inches for kids' Splash Zone slides. See pool policies here: https://www.oceanlakes.com/wp-content/uploads/2016/05/Sandy-Harbor-Pool-Rules-vMay2016.pdf
I am pretty sure it is 46"
