Water Slide Rentals in Newark, DE

Big Wave Party Rentals offers a wide range of inflatable water slides, from smaller slides and wet combo units to towering slides, dual-lane attractions, and wet obstacle courses.

The right choice depends on your riders, available setup space, event size, location, and how much thrill you're looking for. Click any rental above to see its individual details.

Start with your riders. For younger kids, a wet combo or a smaller slide gives them bouncing, climbing, sliding, and splashing in one rental. For serious splash power and a big backyard attraction, look at our 18'–22' slides. For maximum WOW, our 24'–27' slides bring the kind of excitement guests notice before they even get out of the car. Use the Slide Finder at the top of the page, or call us and we'll narrow it down.

Choose the water slide you're interested in, check its availability for your event date, and add it to your cart. Then enter your event information and complete the reservation process.

Without visiting your location, we can't know for sure, so every unit's setup area requirements are posted under “More Info” on its page. It is the customer's responsibility to measure. The units are bigger than you think, and we'd hate to show up on your special day and not be able to set up because of size. Remember that proper setup can also need extra clearance around the unit.

It depends on the specific inflatable and its requirements. Check the individual rental details or call us before booking if adults will be participating.

Your price covers an all-day rental (up to 8 hours) along with delivery, setup, and pickup. A minimum order may apply depending on your location. Prices do not include Delaware rental tax (1.9914%) or any applicable state tax for Maryland and Pennsylvania. Review your selected item's details and checkout information for any event-, location-, or rental-specific requirements and charges.

Enter your event's exact start and end times. We'll make sure your rental is ready to go for your specific start time. A day or two before, we'll text you a delivery window, and we've never been late to an event. Delivery may happen the day before, but we can't guarantee that, so please don't tell the kids.

As early as you can once you know your event date, especially for summer weekends, holidays, school events, and other popular dates. Popular rentals and dates can fill up.

Already know your date? Check what's available before you spend another hour planning around a slide that might already be booked.

We deliver throughout our regular service area, including Newark, Middletown, and Wilmington, DE; Elkton, MD; Landenberg, PA; and surrounding communities. Events outside our normal service area may still be possible depending on location and availability, and additional delivery fees may apply there.

Make sure there's at least 6 ft of access to the setup area. Inflatables can weigh up to 700 pounds, so we need a clear path with no stairs or steep hills.

We're very flexible. We understand the weather doesn't always cooperate. If you or Big Wave decides it's necessary to reschedule, your deposit can be used toward anything on our website. We may require rescheduling based on the current forecast from Weather.com and/or WeatherUnderground.com.

We can't set up some items when the forecast calls for a 30% chance of rain or greater. We also can't set up inflatables with sustained winds over 15 MPH or projected gusts of 15 MPH or more. In that case, you can reschedule or choose replacement items from available equipment. If you cancel within 30 days of the event, the deposit may not be refundable but can be used as a raincheck toward another rental.

Yes, every order requires a $100 deposit. We accept cash or credit cards. If you pay in cash, please have exact change, because our drivers don't carry cash. Final payment by credit card must be made before or at delivery, and a technology fee applies to card payments. We accept company checks only.

Yes. A blower keeps air in the inflatable the entire time, and once it's unplugged the unit deflates. We require an outlet within 100 feet of the unit, or a generator. Big Wave provides the heavy-duty extension cords. No outlet nearby? Add a generator to your order. Questions about water hookups or your setup? Call 302-229-9801 and tell us about your event.

Grass is our favorite and best for the kids. We can also set up on asphalt, concrete, or indoors on a gym or similar floor. We can't set up on rocks, gravel, mulch, or sand, because the constant rubbing wears through the vinyl. An additional surface fee applies to units not set up on grass that need more than 10 sandbags.

Yes and no. Parks are available most months, depending on demand. Because parks are open to the public, the customer must be with the unit at all times, so exact setup and pickup times are harder to accommodate in our busy season (June, July, and August). Generators are a must-rent in a park. Please call to reserve in a park so we can check availability.

Yes. Big Wave Party Rentals is licensed and insured in Pennsylvania, but not every unit is PA approved. Look for units marked PA, MD, DE Approved (or DE/MD/PA), or use the “PA approved” filter in the grid. All units are approved for Delaware and Maryland. See our PA approved inflatables.

We deliver to the University and the surrounding area only for University-sponsored events.

Yes. Nearly every wet combo has a dry version, usually $70 less. Browse our combo bouncers and dry slides, or call us and we'll point you to the right one.

Clean means CLEAN. Our professional team cleans every unit and performs a safety inspection before your event. One customer who has rented from us three years in a row says every rental has been exceptionally clean, and describes our team as professional, kind, knowledgeable, and safety-conscious.
