💦 Wet Mode (Summer)
Connect a standard garden hose and let the water flow. Most slides use just 15–20 gallons per hour — less than an average shower. Kids stay cool, lines stay moving, and the fun doesn't stop.
🍂 Dry Mode (Spring/Fall)
Every water slide in our lineup can run dry — making them perfect for cooler weather, indoor gym events, and school field days outside of summer. Same slide, same fun, no water needed.
🛡️ Safety-First Setup
Every water slide is professionally installed by our trained crew. We don't cut corners on safety — and neither should your rental company.

🎂 Birthday Party Water Slides
Water slides are the most-requested rental for summer birthday parties. The 18' Tropical Dual Lane keeps two lines going at once — cutting wait times in half. For younger kids, the 17' Beach Camper is a great mix of height and approachability. For older kids and teens, the 22' Red White & Cool delivers the big-slide experience they'll remember. Pair any slide with a bounce house combo, tent, and concession machine for the ultimate party setup.
🏫 School Field Day Water Slides
Schools love our water slides for end-of-year field days, reward days, and PBIS celebrations. The 47' Fiji Falls Obstacle is built for high-throughput — obstacle course into a slide keeps lines moving fast. For smaller setups, the 20' Tiki Tide and 20' Jurassic Splash are crowd favorites. We're fully insured with COI available for school districts and parks.
💦 Sizes, Lanes & Styles
Our water slide lineup includes single-lane, dual-lane, and obstacle-course designs ranging from 15 to 47 feet tall. Single-lane slides are great for backyard parties. Dual-lane slides work perfectly for competitions and higher guest counts. Obstacle + slide combos are ideal for field days and festivals where you need constant flow. Every slide can run wet or dry — no water source? No problem.
🔌 Setup Requirements
Water slides require a flat setup area (grass is ideal), a standard 20-amp electrical outlet within 100 feet, and a garden hose for wet use. Most slides use just 15–20 gallons per hour. Larger slides may need two outlets for dual blowers. We bring extension cords, hoses, and all hardware needed. We confirm fit and requirements during booking.
