21ft Double Lane Summer Splash - 21 Feet, Two Lanes, Splash Pool, One Outlet
The 21ft Double Lane Summer Splash is a 21-foot tower slide with two racing lanes and a splash pool landing in the outdoor waterslide rentals lineup. At $495 per day it matches the price of the 18ft Rocky Island Water Slide with Slip N Slide while delivering 3 more feet of height, double the lanes, and a pool at the base. It also runs on a single 110V outlet, the same basic power requirement as a standard 16-foot single-lane slide, making it one of the most setup-friendly premium slides available. The 32-foot run is compact relative to 21 feet of height, which means the drop angle is steep and speed builds quickly through the full lane into the pool.
Setup requires 17 feet of width and 32 feet of clear length. Delivery, setup, and teardown are all handled by our crew. Questions about whether the Summer Splash fits your space or event? Reach the team here or call (512) 294-2221.
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 21ft Summer Splash Delivers at Summer Events
21 Feet and a Pool at the Same Price as an 18-Foot Single-Lane Slide
At $495 the Summer Splash costs the same as the 18ft Rocky Island Water Slide with Slip N Slide but delivers 3 more feet of height, two lanes, and a splash pool. For summer birthday party rentals in Georgetown water slide rentals and across Greater Austin where maximum slide experience per dollar matters, no other slide matches the Summer Splash on that measure. At $50 less than the 22ft Purple Crush it is also the smartest step-down from the top of the double-lane class.
One Outlet for a 21-Foot Double Lane Slide
The Summer Splash runs on a single 110V outlet. The 18ft Rocky Island and 20ft Blue Crush both require two outlets on different circuits. The 22ft Purple Crush needs two outlets as well. The Summer Splash delivers 21 feet and two racing lanes on the same power requirement as any basic single-lane slide. For backyard events and school carnivals where only one outdoor outlet is available, the Summer Splash is often the only double-lane pool option that fits. See our water slide rental FAQ for general setup guidance.
Compact 32-Foot Run, Steep Drop, Real Speed
The Summer Splash runs 32 feet from steps to pool. At 21 feet tall that produces a steeper angle than longer slides at the same height. Speed builds quickly through the shorter run and carries into the splash pool. For summer parties where the thrill of the drop matters, the Summer Splash's geometry delivers a more intense ride per foot than longer 18-foot options. The 32-foot footprint also makes it one of the most space-efficient premium slides in the Greater Austin lineup.
Two Lanes and a Pool Landing Keep the Party Moving
Two simultaneous riders means roughly double the throughput of a single-lane slide at the same height. Every run ends in the splash pool, giving both riders a satisfying finish and a clear exit point for the next pair. For large summer events and birthday parties with active guest lists, two lanes and a pool landing maintain crowd energy through a full 4-hour party better than a single-lane equivalent would. Call (512) 294-2221 to book.
Events Where the 21ft Summer Splash Delivers
Summer Birthday Parties With One Outdoor Outlet
Birthday party rentals where only one outdoor outlet is accessible get the Summer Splash's 21-foot double-lane experience on a single circuit. No second breaker needed. At $495 it matches the price of an 18-foot single-lane slide while delivering three more feet and two racing lanes. Browse all inflatable water slide rental lineup to compare before booking. The overnight rate at $792 suits sleepovers where the pool runs through the next morning.
Neighborhood Block Parties and Large Backyard Events
Block parties and large backyard summer events get a 21-foot double-lane slide that handles high throughput in a 17-by-32-foot space. The splash pool at the base means every rider gets a water landing. The 3-day rate at $1,039.50 covers full holiday weekends at one delivery fee from Jump Around Party Rentals.
School Carnivals and Church Summer Events
School carnival and church summer event rentals get 21-foot height and two lanes on a single outlet, a practical advantage in venues where dedicated power access is limited. Ages 3 and up covers the full K-12 range. The compact 32-foot run fits into tighter carnival layouts than slides needing 40-plus feet. Questions about multi-item orders? Get in touch here.
Corporate Picnics and Community Summer Festivals
Corporate summer events and community festival water attractions get an impressive 21-foot slide that adults take seriously. The racing format and pool landing generate genuine competition. At $495 it fits premium event budgets without reaching top-tier pricing. Learn about the team behind every delivery on our About Us page.

Frequently Asked Questions
How does the 21ft summer splash compare to the 22ft purple crush?
Both are double-lane slides with splash pools. The Purple Crush is 22 feet at $545 and requires two separate 110V outlets. The Summer Splash is 21 feet at $495 and needs only one outlet. Choose the Summer Splash for $50 savings and simpler power requirements. Choose the Purple Crush for the extra foot of height and the purple marble design.
Why does the 21ft summer splash only need one outlet when other slides this size need two?
The Summer Splash is engineered to run on a single blower connected to one 110V outlet. The 18ft Rocky Island, 20ft Blue Crush, and 22ft Purple Crush all need two outlets on separate circuits. The Summer Splash's single-outlet design is a meaningful advantage for backyard and school carnival events where two separate outdoor circuits are not available.
What yard space does the 21ft double lane summer splash need?
The Summer Splash needs 17 feet of width and 32 feet of clear length. At 21 feet tall the 32-foot run is compact for the height, producing a steep, fast drop. Most yards that fit a standard 16-foot slide can handle the 32-foot length. Confirm both dimensions are clear before booking. Call (512) 294-2221 with any space questions.
Is the 21ft summer splash worth the upgrade over the 18ft purple falls?
The Purple Falls is 18 feet at $445 with a pool. The Summer Splash is 21 feet at $495 with a pool. For $50 more you get three additional feet of height, which translates to noticeably more speed and drop. If the event has 20 or more active riders who will appreciate the height difference, the Summer Splash upgrade is worth it.
Does the summer splash water slide have a pool at the bottom?
Yes. The 21ft Double Lane Summer Splash has a splash pool at the base of both lanes. Every rider exits into the pool after the 21-foot drop, giving each run a satisfying, refreshing finish. The pool also creates a clearly defined exit point for the adult supervisor managing the boarding rotation. See our rental FAQ page for additional setup and safety questions.
What rental periods are available for the summer splash water slide?
The Summer Splash is available at day ($495), 8-hour ($544.50), overnight ($792), and 3-day ($1,039.50) rates. The overnight rate suits birthday sleepovers where both lanes stay active through the next morning. 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.
