Browse Our Cupertino Water Slide Lineup

Our Cupertino water slide catalog is organized into four clear categories so it's easy to match a slide to your event, your guest list, and your venue size. Backyard slides in the 15-to-18-foot range fit most Cupertino residential lots — including the well-maintained mid-century homes throughout Garden Gate, Inspiration Heights, and the streets surrounding Memorial Park. Dual-lane and tower slides in the 18-to-22-foot range bring side-by-side racing and faster line throughput for larger gatherings. Wet/dry combo units bundle a bounce house, a slide, and optional water into a single inflatable — useful for the cooler shoulder weekends Cupertino gets in May and September as marine air filters in through the foothill gap. Premium dry slides above 24 feet are sized for school field days, tech-campus events, and church festivals where headcount runs into the hundreds. Every price below is flat-rate and includes delivery, setup, anchoring, sanitation, and pickup within our standard Cupertino service area.

Backyard Water Slides

Backyard water slides are our highest-volume rental for Cupertino residential birthday parties. Each unit needs roughly 25 feet of length and 15 feet of width, plus overhead clearance for the splash arch — a comfortable fit for most Garden Gate, Rancho Rinconada, and central Cupertino lots. The attached splash pool catches runoff so your professionally landscaped lawn stays a lawn. These slides are sized for ages four through fourteen, comfortably handle four to six riders per cycle, and run all afternoon on a standard household outlet.

Dual-Lane & Tower Slides

Dual-lane and tower slides are the smart upgrade when you want competitive racing, faster line throughput, or a centerpiece that older kids and teens won't outgrow halfway through the party. The 22-foot Vortex Corkscrew Waterslide adds a corkscrew turn most rental companies serving Cupertino simply don't stock, and the Giant 22-Foot Double Lane Slide moves roughly twice the riders per hour as a single-lane backyard unit. Both need more overhead clearance and a wider setup footprint, so we always verify yard fit during booking — particularly important on Cupertino's mature, tree-canopied streets near the Monta Vista foothills.

Wet/Dry Combo Slides

Wet/dry combo slides are the most flexible rentals in our Cupertino catalog. Each combo blends a bounce-house jump area with an attached slide, basketball hoop, and climbing wall — and you choose at booking time whether to run it wet for a hot Saturday or keep it dry for a cooler weekend or indoor event. That dual-mode flexibility suits Cupertino's microclimate well, where afternoon foothill breeze can quickly cool a yard that started the morning warm. Combos are also a strong fit for school carnivals that may shift dates, multi-weekend church youth programs, and busy two-event weekends. They also save real yard space versus renting a separate bouncer and slide.

Premium Dry Slides

Premium dry slides are built for institutional-scale events — Cupertino Union School District field days, end-of-year carnivals at Fremont Union High campuses, tech-campus picnics, church festivals, and city-wide fundraisers where you need to move hundreds of guests through an attraction in a short window. The 27-foot Mega Double Lane Cliff Hanger is our biggest commercial unit and a regular at Cupertino-area PTA carnivals. The 34-foot Long Lava is built for length over height, which works well in school gyms and indoor church family-night events through the cooler months.

What's Included With Every Water Slide Rental

Plenty of inflatable rental companies serving Cupertino quote an attractive headline price and then layer on charges for delivery, setup, sanitation, anchoring hardware, and pickup — by the time you reach checkout, the slide has quietly grown 30 to 50 percent. iJump doesn't operate that way. Every water slide rental in Cupertino, CA includes the four items below at no additional charge.

Free delivery, setup, and teardown are standard across our 50-plus-city Bay Area service area, which keeps all the heavy work on our crew. Warehouse-cleaned and sanitized — every slide is fully cleaned at our facility between events, not given a fast on-site wipe-down between drop-offs, because we wouldn't put our own kids on equipment that wasn't truly clean. Anchoring straps, sandbags, a blower, and a GFCI extension cord come included with every rental, sized to your specific setup surface — grass gets direct stakes, concrete and asphalt get sandbags, and the crew chooses the right method on-site. A 1-to-4-hour early arrival window means your full five-hour rental clock starts when your event starts, not when the truck pulls into your driveway. Setup time never cuts into your rental window.

 

Honest Water Slide Rental Pricing in Cupertino

Water slide rental pricing in Cupertino, CA varies more than most customers expect, and we'd rather explain it openly here than tuck it behind a quote form. Below is what our slides actually cost, what drives the differences between them, and what we would never charge you extra for.
 
Jumper and Party Equipment Rental

How much does a water slide rental cost in Cupertino, CA?

iJump's water slide rentals currently range from $399 for the 3in1 Water Combo to $899 for the 27-foot Mega Double Lane Cliff Hanger Dry Slide. The most-booked price band — where the majority of Cupertino backyard birthday customers land — is $459 to $549 for a 16-to-18-foot backyard water slide with an attached pool. Six factors drive where your particular rental lands inside that range: slide height, lane count, wet versus dry use, delivery distance from our warehouse, weekend versus weekday timing, and whether you're adding multi-day or overnight extensions. Every product card price includes free delivery, setup, anchoring, sanitation, and pickup within our standard service area.
Jumper and Party Equipment Rental

What's the difference between a backyard slide and a tower slide?

A backyard slide stands 15 to 18 feet tall, fits a standard Cupertino residential yard, runs one or two lanes, and is designed for ages four through fourteen. A tower slide stands 20 to 27 feet tall, is built to commercial-grade specifications, moves significantly more riders per hour, and is engineered for schools, churches, corporate picnics, and large community gatherings. Tower slides also need more overhead clearance and a wider footprint, so we always verify the venue can accommodate one before delivery — particularly important for Cupertino's mature mid-century properties where established trees and side-yard fencing can limit access.
 

What we never charge extra for

Local delivery anywhere inside our 50-city service area is always free. Setup, anchoring, and teardown are always free. Standard sanitation between rentals is always free. The blower, the GFCI extension cord, the sandbags, the stakes, and the safety inspection are always included with the slide itself. If a charge ever surprises you on an iJump invoice, ask us — we'll walk you through it line by line.
 

Why iJump Is Cupertino's Most-Reviewed Inflatable Rental Company

Every claim on this page is independently verifiable. That matters in a category where most websites lean on phrases like “the best” or “#1” without ever showing the math behind them. Here is what backs ours.

310+ Yelp Reviews from Real Bay Area Customers

iJump Party Rentals' Yelp profile shows 310-plus reviews from customers across Cupertino and the broader South Bay — the highest verified third-party review count of any inflatable rental company serving this market. We don't pay for reviews, and we don't filter out the critical ones. You can read every one of them directly on Yelp before you decide to book.

Family-Owned and Operated Since 2008

iJump has been a family-owned business serving Cupertino and the rest of the South Bay since 2008. Our owner answers the phone himself most days. Our warehouse, our trucks, and our crew are all local — we are not a national franchise, and we are not a marketplace forwarding your job to a partner shop. When something goes right or wrong on your rental, you're dealing directly with the people who own the company.

Lead-Free Vinyl Tested Below 90 PPM

Every iJump inflatable is built from commercial-grade vinyl that tests below 90 parts per million for lead content — comfortably under the 300 PPM ceiling set by the federal Consumer Product Safety Improvement Act (CPSIA) and below the stricter limits established under California Proposition 65. That's measurable, not marketing language. We can provide test documentation on request.

Fully Licensed, Insured, and Approved for City Events

iJump carries comprehensive commercial general liability insurance, and our Certificate of Insurance is available on request — just email or call and we'll send it the same day. We are also an approved inflatable vendor for several Bay Area municipal park departments, which means we meet the higher insurance and safety thresholds required to rent at public parks. (Park-approval status updates periodically; confirm during booking for your specific Cupertino venue.)

Events We Power Across Cupertino & the Bay Area

iJump's water slides show up at nearly every type of Cupertino event. Backyard birthday parties remain our biggest single category — from toddler birthdays in Garden Gate to teen pool parties in Inspiration Heights and graduation celebrations off Bubb Road — and the 16-to-18-foot backyard slides with attached pools are usually what families book. School field days, end-of-year carnivals, and PTA fundraisers are the second-biggest segment, typically pairing a 22-to-27-foot dual-lane slide with concession machines and obstacle courses for a complete carnival setup. Multiple Cupertino Union School District elementaries and middle schools have rented from us multiple seasons in a row, and Fremont Union High campuses — including Monta Vista High, Cupertino High, and Homestead High over in the Sunnyvale border area — book us regularly for spirit-week and grad-night events.

Church festivals and youth-group events are a steady year-round category — wet in summer, dry in fall and spring, often paired with combo bouncers and our interactive game rentals. Corporate picnics and team-building events drive a significant share of our Cupertino weekday bookings, given the density of major tech employers along Stevens Creek Boulevard, De Anza Boulevard, and the Apple Park corridor; these events typically lean toward our premium dry slides plus team-building game packages. Quinceañeras, Sweet 16s, graduations, and multigenerational family reunions round out our weekend calendar from May through September. HOA block parties in Cupertino's master-planned subdivisions and condo communities book early for prime summer weekends — plan ahead.

 

How Booking Works in 4 Steps

Booking a water slide with iJump is designed to be fast — most Cupertino customers move from “choosing a slide” to “date locked in” in under five minutes.

1

Browse and select. Pick your event date on our online calendar, then browse the lineup above. Add the water slide you want — plus any tables, chairs, generators, or concession machines — to your cart. Our system displays real-time availability 24/7, so what you see open is actually open.

2

Reserve with a deposit. Complete checkout through our secure system. A deposit locks in your date and your specific equipment selections. You'll receive an instant confirmation, plus a reminder ahead of your event date.

3

We deliver and set up. Our crew arrives one to four hours before your scheduled event start, unloads the slide, inflates it, anchors it using the correct method for your surface, safety-checks every component, and walks you through operation before they head out.

4

We pick everything up. At the end of your rental window, our crew returns, deflates the slide, breaks down all the equipment, and hauls it away. You don't move, lift, fold, or clean anything.

 

What Cupertino Families Say About Their Water Slide Rentals

 

Frequently Asked Questions About Water Slide Rentals in Cupertino

Q.

How much does a water slide rental cost in Cupertino, CA?

A. iJump's water slide rentals range from $399 to $899, with most Cupertino backyard customers landing between $459 and $549 for a 16-to-18-foot slide with attached pool. Price varies by slide height, lane count, wet versus dry use, and delivery distance. Every quoted price includes free delivery, setup, anchoring, sanitation, and pickup within our standard service area.
Q.

How long is a standard water slide rental?

A. Our standard rental period is five hours of active use, and the clock starts at your scheduled event time — not when our crew arrives at your Cupertino address. Setup and takedown happen outside the rental window at no extra charge. If you need more time, extended hours and overnight rentals can be added when you book.
Q.

What surfaces can a water slide be set up on?

A. Our water slides can be set up on grass, dirt, asphalt, or concrete. Grass is preferred because it allows direct staking and provides a softer landing. On Cupertino driveways or patios we anchor with heavy-duty sandbags. Rocky or sharply uneven ground isn't safe for inflatable setup. The crew needs at least three feet of clear path width to bring equipment to the setup spot.
Q.

Do you deliver, set up, and pick up — and is that included?

A. Yes — free delivery, free setup, free anchoring, and free pickup are included with every water slide rental within our 50-plus-city Cupertino and Bay Area service area. Nothing on your invoice is added on top of the slide price for standard local service. If you're outside the standard radius, we'll quote a transparent mileage fee up front before you book.
Q.

Are your water slides cleaned and sanitized between rentals?

A. Every iJump inflatable is fully cleaned and sanitized at our warehouse between events — not a fast on-site wipe-down. We disinfect interior surfaces, slide lanes, and pool linings using commercial-grade sanitizer, then inspect every seam and anchor point before the unit goes back on the truck. We hold ourselves to the standard we'd want for our own kids.
