Hear from Our Customers
You know that moment when every kid at the party is laughing, splashing, and having the time of their lives? That’s what happens when you rent the right water slide equipment from people who actually know what they’re doing.
No more worrying about whether the equipment will show up on time or if it’s safe for your kids. No more scrambling to find backup entertainment when something goes wrong. Just pure fun that keeps everyone entertained for hours.
Your guests will remember this party long after they go home. Parents will ask where you found such great equipment. And you’ll actually get to enjoy your own event instead of stressing about whether everything’s working properly.
The Big Bounce Theory has been the go-to party rental company for North Great River families since 2007. We’re not just another rental business—we’re your neighbors who happen to specialize in turning ordinary backyards into extraordinary experiences.
What makes us different? We actually show up when we say we will. Our equipment is clean, safe, and properly maintained. And we handle everything from delivery to setup so you don’t have to figure out how to assemble a massive inflatable water slide in your driveway.
We serve families throughout Nassau and Suffolk counties, including the Hamptons and Montauk. When you’re planning an event in North Great River, you want someone who understands the local area, knows how to navigate Long Island logistics, and has the experience to handle whatever weather throws at your party.
Here’s exactly what happens when you book with The Big Bounce Theory. First, you tell us about your event—date, location, number of guests, and what kind of fun you’re looking for. We’ll recommend the right water slide based on your space and crowd.
Next, we handle the logistics. We’ll confirm your delivery window, explain setup requirements, and answer any questions about power needs or space requirements. No surprises, no hidden details you find out about later.
On event day, our team arrives with everything needed for setup. We handle the installation, test everything to make sure it’s working properly, and give you a quick walkthrough of the equipment. When your event’s over, we come back to break everything down and haul it away. You focus on enjoying the party—we handle the heavy lifting.
Ready to get started?
Your water slide rental includes professional delivery, complete setup, and pickup when your event ends. The equipment arrives clean, tested, and ready to provide hours of entertainment for kids and adults alike.
North Great River’s summer weather is perfect for water slide parties, and The Big Bounce Theory’s equipment is designed to handle Long Island’s outdoor conditions. Our inflatable water slides come in various sizes to fit different backyards and group sizes, from intimate birthday parties to large community events.
We also provide event essentials like tents for shade, tables and chairs for parents, and concession machines if you want to add snacks or drinks to the mix. For corporate clients in the North Great River area, we offer custom branding options that turn your company event into a memorable team-building experience that employees actually enjoy.
Most residential water slides need a flat area that’s roughly 30 feet long by 15 feet wide, with at least 6 feet of clearance on all sides for safety. The Big Bounce Theory will do a site visit or work with you over the phone to measure your space and recommend the right size equipment.
You’ll also need access to a standard electrical outlet within 100 feet of the setup area, since the blower that keeps the slide inflated needs continuous power. We bring heavy-duty extension cords, but having power nearby makes setup smoother.
If your yard has slopes, trees, or other obstacles, don’t worry—we’ve been setting up water slides in North Great River backyards for years and know how to work around most challenges. We’ll let you know upfront if your space won’t work rather than showing up on party day with bad news.
Light rain actually makes water slides more fun, but safety comes first. The Big Bounce Theory monitors weather conditions and will contact you if severe weather threatens your event. We have flexible rescheduling policies for situations beyond anyone’s control.
For North Great River events, we typically recommend having a backup plan for indoor activities, especially during Long Island’s unpredictable spring and fall weather. Summer thunderstorms usually pass quickly, so many parties can continue after a brief delay.
If you need to reschedule due to dangerous weather conditions like lightning or high winds, we’ll work with you to find a new date without additional fees. We’d rather have everyone safe and reschedule than risk anyone getting hurt on unsafe equipment.
Safety is non-negotiable. All of The Big Bounce Theory’s water slides are designed with age-appropriate features and weight limits clearly marked. We’ll recommend specific equipment based on your guest list—toddler-friendly slides for younger kids, and bigger slides that can handle teenagers and adults.
Each water slide rental includes safety instructions and guidelines that we’ll review with you during setup. The equipment is inspected before every rental and meets all New York safety requirements for inflatable amusements.
We’re fully licensed and insured, which means you’re covered if anything unexpected happens. But with proper supervision and following the safety guidelines, water slide injuries are extremely rare. Most problems happen when people don’t follow weight limits or try to use equipment in ways it wasn’t designed for.
For North Great River water slide rentals, booking 2-3 weeks ahead gives you the best selection and guarantees availability for your preferred date. Summer weekends fill up quickly, especially Memorial Day through Labor Day when everyone’s planning outdoor parties.
If you’re planning a last-minute event, call anyway—we sometimes have cancellations or can accommodate short-notice bookings, especially for weekday events. But popular dates like graduation weekend or the Fourth of July book up months in advance.
School events and corporate parties often have more flexibility with dates, so you might be able to book closer to your event. The key is calling as soon as you know your date rather than waiting and hoping something will be available.
Your rental fee covers the water slide equipment, professional delivery to your North Great River location, complete setup and testing, and pickup after your event ends. We bring all the blowers, stakes, and safety equipment needed to operate the slide properly.
You provide the water connection (standard garden hose) and electrical power. We handle everything else, including cleaning the equipment before it arrives at your location. No hidden fees for setup, delivery within our service area, or basic equipment needs.
Additional services like extended rental periods, multiple pieces of equipment, or special event add-ons are priced separately. We’ll give you a complete quote upfront so you know exactly what you’re paying before you book. No surprises on party day.
Absolutely. The Big Bounce Theory regularly provides water slide rentals for corporate events, company picnics, and team-building activities throughout the North Great River area. Corporate clients appreciate our professionalism, reliability, and ability to handle larger-scale events.
We offer custom branding options that can incorporate your company logo or colors into the event setup. This works especially well for client appreciation events or employee family days where you want to create a memorable experience that reflects well on your business.
Corporate events often have different requirements than backyard parties—things like insurance certificates, specific setup times, or coordination with other vendors. We’re experienced with these needs and can provide all necessary documentation and work within your event timeline.
