Complete Your Water Party
Wet combo bouncers bring the bounce house and water slide fun together — add these to make your summer setup even better.
Why Wet Combos Are So Popular
Wet combo bouncers combine two of the best party rentals into one: a bounce house for active play and a water slide for cooling off.
Bounce + Water Slide
Perfect Summer Rental
Great for Younger Kids
Non-Slip Bounce Floors on Every Wet Combo
Every wet combo bouncer we offer includes a non-slip bounce floor inside the bounce house area. When kids climb in with wet feet, this upgraded surface helps give them better traction while bouncing — a thoughtful detail included on all of our wet combo rentals.
Balloon Jump-N-Splash
The Balloon Jump-N-Splash is one of the easiest wet combos to love — bright, fun, and perfect for birthday parties where you want a clean party look with plenty of water fun.
It gives kids the bounce house experience plus a water slide and splash area, making it a strong pick for summer birthdays and backyard parties.

Power & water: Wet combos need 1 standard 110V outlet within 100 feet and access to a working water spigot with a hose nearby.
☔ Weather & Water Rentals
Wet combos are built for summer fun, but safe weather still matters. Heavy rain, lightning, or high winds are not safe for inflatable use.
Bad weather forecast? Reach out the night before and we can reschedule at no charge.
📏 Space & Setup
Grass is ideal for wet combos because it gives the best anchoring and helps with water runoff.
Setup area: Make sure the space is flat, clear of sticks, rocks, pet waste, low branches, and overhead power lines. Each product page lists exact dimensions.
Wet Combo Bouncer FAQs
