18ft Rocky Island Water Slide - 18 Feet Tall, 50-Foot Slip N Slide Run, Rocky Island Design
The 18ft Rocky Island Water Slide with Slip N Slide delivers 18 feet of tower height, a slip n slide run extending the total ride to 50 feet, and a rocky island tropical design that stands apart from every other slide in the backyard water slide and slip and slide rentals lineup. Riders climb to the top, drop 18 feet, carry momentum through the slip n slide section, and exit at the far end of a 50-foot run. For summer birthday parties, large outdoor events, and any gathering where the primary water attraction needs to genuinely impress, the Rocky Island delivers the full tower-plus-extension experience at a price point below the 20 and 22-foot slip n slide options.
Two separate 110V outlets on different circuits are required for the blowers - not two outlets on the same breaker. Confirm both are available at your location before booking. Setup also requires 14 feet of width and 50 feet of clear length. Questions about power or space? Reach the Jump Around Party Rentals team here or call (512) 294-2221 before placing your order.
Day rate $495. Eight-hour, overnight, and 3-day rates available. Friday early delivery for Saturday events is often available at no extra charge. Book online or call (512) 294-2221.

Why the Rocky Island Water Slide Delivers at Summer Events
18 Feet Into a Slip N Slide - a 50-Foot Ride at the Entry Price of the Format
The tower-plus-slip-n-slide format starts at the Rocky Island. The 20ft Blue Crush at $525 and the 22ft Xtreme Tropical at $595 are the higher-end versions of the same format at greater heights. The Rocky Island delivers the same climb-drop-slide sequence at 18 feet for $495 - $30 less than the Blue Crush and $100 less than the Xtreme Tropical. For summer birthday party rentals in Killeen water slide rentals and across Greater Austin where the slip n slide experience is the goal and 18 feet is enough height, the Rocky Island is the right entry point.
Rocky Island Design - Distinct From Every Other Slide in the Lineup
The rocky island tropical theme gives the Rocky Island Water Slide a distinct visual identity. It is not the solid patriotic colors of the All American family, not the smooth marble patterns of the Wave Runner or Blue Marble, not the Lego bricks or the deep blue palm tree designs. The rocky island aesthetic - rugged textures combined with tropical coloring - creates a look that photographs differently from everything else in the lineup and works naturally for adventure-themed birthday parties, island events, and any summer outdoor event where a standard water slide visual would blend into the background.
Two Outlets Required - Confirm Before Booking
The Rocky Island requires two separate 110V outlets on different circuits to maintain pressure across the 50-foot structure. Two outlets on the same breaker will not work. This is the same requirement as the Blue Crush and Xtreme Tropical - standard for slides in this length class. Our crew handles the connections at delivery. Your job is confirming those two separate outlets exist at the location before booking. For pre-event setup and safety questions our inflatable rental safety FAQ covers the most common ones.
50 Feet of Ride on a 14-Foot-Wide Footprint
At 14 feet wide the Rocky Island is narrower than the Beach Party Waterslide (16ft) and the same width as the standard 16-foot tower slides. For events with a yard that has the 50 feet of length but not a wide open space, the 14-foot width is practical. The slip n slide extends directly from the tower base so the full 50-foot run is contained within 14 feet of width. Call (512) 294-2221 to confirm your space before booking.
Events Where the Rocky Island Water Slide Delivers
Summer Birthday Parties Wanting Waterpark Scale
Birthday party rentals where the goal is a full waterpark-style ride experience get 18 feet of tower height and 50 feet of total run. The rocky island tropical design gives the slide visual presence beyond a standard inflatable. Ages 3 and up covers the full guest range. The overnight rate at $792 keeps both tower and slip n slide ready through the next morning for birthday sleepovers. Browse all inflatable waterslide rental lineup to compare the full lineup.
Adventure and Island-Themed Summer Events
Adventure-themed birthday parties and island-themed summer events get a water slide whose design genuinely fits the theme. The rocky island aesthetic - tropical textures and island coloring - pairs naturally with pirate, explorer, and island-escape party themes without any additional decoration. At $495 it is accessible as the centerpiece attraction at a themed summer event with a full decoration budget committed elsewhere.
Large Community Events and Multi-Attraction Festivals
Community summer festival rentals that need a premium water attraction get 18 feet and 50 feet of run at a price point between the 18-foot standard slides and the 20-22-foot premium options. The rocky island visual presence stands out in a multi-attraction event layout. The 3-day rate at $1,039.50 covers full holiday weekends at one delivery fee. Questions on multi-item orders? Get in touch here.
Corporate Summer Events and End-of-School Celebrations
Corporate outdoor event rentals and end-of-school summer celebrations where the primary water attraction needs to hold adult attention get the Rocky Island's 50-foot run. The tower drop generates real speed that carries through the slip n slide section. Ages 3 and up means the full age range from young children to adults participates without age-based exclusions. The rocky island design photographs well at any outdoor event with a summer theme.

Frequently Asked Questions
How does the rocky island water slide compare to the blue crush and xtreme tropical?
All three are tower slides with slip n slide extensions. The Rocky Island is 18 feet with a 50-foot run at $495. The Blue Crush is 20 feet, 53-foot run, at $525. The Xtreme Tropical is 22 feet, 57-foot run, at $595 with two water barrels also required. The Rocky Island is the entry point at the lowest height and price.
Why does the rocky island water slide need two outlets?
The Rocky Island requires two separate blowers to maintain pressure across its 50-foot structure - one blower cannot handle the full unit. Each blower needs its own 110V outlet on a separate circuit. Two outlets on the same breaker will trip it. Confirm both separate outlets exist at your location before booking. Our crew handles all connections at delivery.
How much yard space does the rocky island water slide need?
The Rocky Island requires 14 feet of width and 50 feet of clear length - both setup area and actual size are the same in the CMS. Confirm the full 50 feet are available. The 14-foot width is narrower than the Beach Party Waterslide (16ft) and the same as most standard 16-foot tower slides. Call (512) 294-2221 to confirm your space before booking.
How does the rocky island compare to the 18ft all american water slide?
Both are 18-foot single-lane slides. The All American runs 34 feet, operates wet or dry, needs one outlet, and costs $375. The Rocky Island runs 50 feet, needs two outlets, is wet only, and costs $495. Choose the Rocky Island for the 50-foot slip n slide run. Choose the All American for wet or dry flexibility and the lower price.
Does the rocky island water slide need water barrels?
Based on the CMS specs, no water barrels are listed for the Rocky Island - only two separate 110V outlets and a garden hose. This distinguishes it from the Xtreme Tropical Water Slide, which requires two barrels in addition to two outlets. Check our rental safety FAQ page for additional setup guidance, and confirm with (512) 294-2221 before your event day.
What rental periods are available for the rocky island water slide?
The Rocky Island is available at day ($495), 8-hour ($544.50), overnight ($792), and 3-day ($1,039.50) rates. The overnight rate suits birthday sleepovers. The 3-day rate covers full holiday weekends at one delivery fee. Friday early delivery for Saturday events is often available at no extra charge. Call (512) 294-2221 to book or confirm availability.
