The Big Kahuna Double Lane Water Slide - Wet, Dry, or Both
The 16ft Double Lane Big Kahuna is a side-by-side racing slide that runs wet as a full inflatable water slide or completely dry without any water - making it one of the most flexible options in the inflatable water slide rentals in Greater Austin lineup. Two riders race simultaneously down the blue lanes, and decorative inflatable red fish at each exit add a playful detail that younger kids love. The wet/dry capability is what sets the Big Kahuna apart: it works at summer birthday parties with the hose running, and it works equally well at indoor gymnasiums, fall school events, or any venue where water is not practical. One slide, two uses.
Rated for ages 3 and up with an 18-by-32-foot setup footprint, the Big Kahuna fits in larger residential backyards and open outdoor spaces. One standard 110V household outlet powers the blower, and adult supervision from your party is required throughout. Families looking at Cedar Park water slide rentals for summer events will find the wet/dry flexibility especially useful when the weather is unpredictable or the party venue has restrictions on standing water.
Base rate is $335 for a day rental with 8-hour, overnight, and 3-day options also available. For Saturday events, Friday early delivery is often available at no additional charge. Book online or call (512) 294-2221 to check Friday availability for your date.

Why the Big Kahuna Works at Your Event
Wet or Dry - One Slide, Every Venue
Most inflatable water slides are wet-only, which means the venue has to accommodate water runoff, grass can get churned up, and any indoor or late-season event is off the table. The Big Kahuna removes all of those constraints. Run it with water for a full summer backyard water slide party. Run it completely dry for a fall school carnival, an indoor gymnasium event, or any venue where standing water is a problem. Same slide, same racing format, same kids having the same amount of fun - no water required when the situation calls for it.
Two Lanes Keep the Race Going All Day
The double lane format turns a standard kids water slide rental into a competition. Two riders go simultaneously, one wins, both loop back to race again immediately. That competitive cycle keeps kids on the ride longer and keeps the line moving faster than a single-lane outdoor water slide rental at the same price point. For birthday party rentals where you need an attraction that holds attention for three or four hours, the racing element does that work without any extra effort from the event organizer.
Details Kids Notice - Red Fish at Every Exit
The Big Kahuna features decorative inflatable red fish at the exit of each lane - a small design detail that generates a real reaction from younger kids who spot them on the way down. It is the kind of thing that makes a slide feel like a genuine attraction rather than a plain-colored inflatable, and it photographs well for the birthday party images parents share afterward. Backyard party rentals that want visual interest without paying for a themed slide get it built into the Big Kahuna's design.
Flexible Rental Periods with Optional Early Delivery
Day, 8-hour, overnight, and 3-day rates give you full control over how long the slide stays. For Saturday events, Jump Around Party Rentals can often deliver the slide the day before at no additional charge when the schedule allows - so the slide is already set up and ready when guests arrive rather than being assembled while the party is starting. Call (512) 294-2221 when booking to ask about Friday delivery for your date.
Events Where the Big Kahuna Delivers
Summer Birthday Parties
Summer birthday party rentals get the double lane racing format with water flowing and the red fish detail giving the slide personality beyond a plain-colored inflatable. At $335 for a day rental, the Big Kahuna delivers genuine backyard water slide party value at the same price as a single-lane option. Ages 3 and up means every guest can participate, from the youngest child at the party to parents who want in on the race.
School Carnivals and Fall Events
School carnival game rentals and fall field day events that cannot use water get the full double lane slide experience in dry mode. The Big Kahuna is one of the few inflatable water slides that works as a fall event attraction without modification. Kids still race two at a time, the competitive energy is identical, and no one has wet shoes or wet grass to manage for the rest of the afternoon.
Community Festivals and Neighborhood Events
Outdoor event rentals for neighborhood block parties and community summer festivals benefit from the double lane throughput - two kids per cycle keeps the line moving at large events. The wet/dry option also makes the slide practical for events where water access is limited to a single outdoor spigot, since the organizer can choose dry mode rather than worrying about water supply and drainage for a full-day event.
Church Events and Indoor Venues
Church events and indoor gymnasium setups get a double lane racing slide that actually works in the space without water damage concerns. Run dry, the Big Kahuna installs on a gymnasium floor with nothing more than a 110V outlet and delivers the same competitive racing experience that makes it popular at outdoor summer events. For kids party rentals at indoor venues that want a slide attraction rather than a bounce house, the dry mode Big Kahuna is one of the best options available.
How the Big Kahuna Rental Works
1
Book and Choose Wet or Dry
Book online or call (512) 294-2221. Let us know at booking whether you plan to run the slide wet or dry so the crew can confirm your water setup plan or confirm that no water connection is needed. Ask about Friday early delivery if your event is on a Saturday.
2
Delivery and Setup
Our crew delivers and inflates the full slide before your event window. For Saturday events, we can often set up the day before so everything is ready when guests arrive. One standard 110V outlet is all that is required. The slide is tested and ready to race before your party starts.
3
Race Down, Loop Back
Two riders position at the top, push off, race past the red fish, and land at the bottom. Your adult supervisor manages the line. Rounds run continuously throughout the rental window - wet for the summer splash experience, or dry if the venue or weather calls for it.
4
We Return and Remove
When your rental period closes, Jump Around Party Rentals returns to deflate and remove the full slide. All teardown is handled by our crew with no disassembly required from your party.

Frequently Asked Questions
What makes the Big Kahuna different from a standard water slide rental?
Two things. First, it has two side-by-side lanes so two riders race simultaneously rather than one at a time. Second, it runs wet as a full water slide or completely dry without water - which makes it usable at indoor venues, fall events, and anywhere standing water would be a problem. Most inflatable water slide rentals are wet-only single-lane options. The Big Kahuna covers both formats at the same rental price.
How does the wet/dry feature work?
For wet operation, connect a standard garden hose to the water inlet on the slide and water flows down the lanes continuously while the blower keeps the unit inflated. For dry operation, simply do not connect a hose. The slide inflates, the lanes are ready, and riders go down without any water. Let Jump Around Party Rentals know at booking which mode you plan to use so the crew can confirm the setup plan for your venue.
What are the rental period options and pricing?
Day rate is $335, 8-hour rate is $368.50, overnight is $536, and 3-day is $703.50. For Saturday events, Friday early delivery is often available at no additional charge when the schedule permits - the slide is fully set up and ready before your party starts rather than being assembled while guests arrive. Call (512) 294-2221 to confirm Friday availability when booking.
How much space does the Big Kahuna require?
The setup area is 18 feet high, 16 feet wide, and 32 feet long. The slide itself is 16 feet high, 15 feet wide, and 28 feet long. The setup footprint is slightly longer than some 16-foot slide options, so confirm your available yard or venue space before booking. The slide works on grass, concrete, asphalt, and gymnasium floors. Call (512) 294-2221 with any site-specific questions.
Can the Big Kahuna be used indoors?
Yes, in dry mode. The slide requires 18 feet of ceiling clearance, a 16-by-32-foot floor area, and one 110V outlet. No water connection is needed in dry mode. Gymnasiums and large event halls that meet the clearance and space requirements can accommodate the Big Kahuna in dry mode for fall carnivals, school events, and indoor birthday parties. Call (512) 294-2221 before booking an indoor setup to confirm your venue dimensions work.
Does the rental include delivery and setup?
Yes. Every rental includes delivery, full setup, and teardown. Jump Around Party Rentals handles all of it. No assembly or disassembly is required from your party. Browse the full inflatable water slide rental lineup to compare other options available across Greater Austin.
