Inflatable water slides may cost more to rent than dry slides because of the additional labor required for setup and the equipment needed to operate the inflatable as a water slide. Many inflatable slides can also accommodate the weight of adults, so be sure to ask. Here's how Lone Star Bounce handles the cost difference for the same 30x10x18-foot inflatable when rented as a dry slide or as a water slide:
Dry slide: $250
Water slide: $325
