Swim-diaper-only
Definition
A posted policy at many splash pads requiring children not yet potty-trained to wear a reusable or disposable swim diaper at all times in the spray zone, with regular diapers strictly prohibited.
The 'swim-diaper-only' rule is the single most enforced policy at municipal splash pads. Regular disposable diapers swell with water, fall apart, and release absorbent gel into the floor drains, where it clogs the recirc system and shuts the pad down for cleaning.
Reusable swim diapers (Charlie Banana, ALVABABY) are the gold standard for pad operators because they contain solids without the gel-blowout problem. Some pads provide loaner swim diapers at the attendant kiosk for $2–$5; many do not. Bring two clean ones per young child.
