Your event becomes the one everyone talks about. Kids who usually get bored after twenty minutes are sliding, laughing, and asking if they can stay longer. Parents actually get to relax instead of scrambling to keep everyone entertained.
You’re not just renting a water slide—you’re buying yourself peace of mind. No more wondering if the equipment will show up, if it’s clean, or if it’s safe. No more backup plans because the company you hired doesn’t return calls.
The setup happens before your guests arrive. The takedown happens after they leave. Everything in between is just pure fun, exactly like you planned it.
The Big Bounce Theory has been serving Old Westbury and Nassau County families since 2007. We know what it takes to deliver the kind of quality that matches this community’s standards.

Commercial-grade inflatable water slides with built-in safety features: safety nets, entrance ramps, and splash pools at the bottom of each unit. These aren’t backyard inflatables—they’re the same quality equipment used by professional event companies.

In Old Westbury, where summer entertaining is serious business, you need equipment that can handle everything from intimate family gatherings to larger community events. Our inventory includes single and dual-lane options, ranging from 13 to 22 feet tall, so there’s something appropriate for every age group and yard size.
For Old Westbury events, book as early as possible, especially for summer weekends and popular dates like Memorial Day, July 4th, and Labor Day. Peak season fills up quickly in Nassau County.
That said, we do accept last-minute calls when equipment is available. If you’re planning something spontaneous, it’s worth calling to check availability. We understand that sometimes the best parties happen on short notice.
The earlier you book, the more options you’ll have for specific slides and delivery times. But don’t let timing stop you from calling if you need something soon.
Every water slide comes with built-in safety features: safety nets around the climbing area, proper entrance ramps, and splash pools at the bottom for safe landings. These are commercial-grade units, not residential inflatables.

Absolutely. We have slides ranging from 13 feet to 22 feet tall, designed for different age groups and comfort levels. Smaller slides work great for younger children, while the larger units thrill teenagers and adults.
Many Old Westbury families host multi-generational events, so we understand the need for equipment that works for everyone. We can recommend the right size based on your guest list and help you choose options that keep everyone engaged.
Dual-lane slides add a competitive element that older kids and adults love, while single-lane options work perfectly for smaller groups or younger children who prefer a gentler experience.
We monitor weather conditions closely and will work with you if severe weather threatens your event. Light rain usually isn’t a problem for water slides, but we prioritize safety above everything else.
If conditions become unsafe, we’ll help you reschedule without penalty. We understand that Old Westbury events often involve significant planning and investment, so we’re flexible when weather doesn’t cooperate.
For events with uncertain weather, we can discuss backup options or indoor alternatives. The key is communicating early so everyone knows the plan if conditions change.
