Complete the Summer Party
Add a few extras to turn your water slide rental into a full event experience.
18' Purple Hurricane Water Slide
This is our go-to water slide for summer parties — tall enough to feel exciting, backyard-friendly enough for most setups, and one of the first slides to book up on hot weekends.
It's the perfect mix of speed, size, and fun for backyard birthdays, family parties, and mixed-age groups that want a true water slide experience without going too big.

Water Slide Rental FAQs
Our standalone water slides range from 18 feet to 22 feet tall — these are full commercial-grade units, not backyard toys. Each product page lists exact height and dimensions.
Water slides are standalone — taller, faster, pure sliding action. Wet combos combine a bounce house with a smaller water slide in one unit. If you want the biggest thrill, go with a standalone water slide. If you want bounce + splash in one, go wet combo.
Water slides start around the mid-$300s for 4 hours depending on size. Extended rentals, overnight (+35%), and 2-day (+65%) options are available. Delivery fee is calculated at checkout based on your address.
As early as possible. Water slides are our fastest-booking summer rentals and many weekend dates in June, July, and August fill up 2–4 weeks ahead. If you have a specific date and a specific slide in mind, book at least 3–4 weeks out for the best selection.
A standard garden hose long enough to reach the setup area, plus access to one 110V outlet within 100 feet for the blower. We handle delivery, setup, water connection, safety walkthrough, and pickup. If you don't have an outlet within 100 feet, we offer generator rentals.
Yes — our commercial-grade water slides are built for riders of many ages. Each product page lists weight limits and recommended usage. We always recommend reviewing the safety rules before riders go on, especially for younger kids.
No — water slides require a grass setup. The stakes anchor the slide securely into soft ground, and the grass also allows water to drain naturally during your rental. For hard surfaces, we'd recommend a dry bounce house or dry slide with weighted anchors instead.
