Which areas around Austin and San Antonio do you deliver inflatable dry/wet water slides to?
We deliver Austin Wet & Dry Slide Rentals and San Antonio Water Slides, plus surrounding cities including Pflugerville Water Slides, Kyle Water Slides, Cedar Park Water Slides, Georgetown Water Slides, New Braunfels Water Slides, and San Marcos Water Slides. Our crews deliver across Travis, Williamson, Comal, and Bexar counties for schools, churches, and backyard parties.
Can inflatable slides in Austin and San Antonio be rented for both wet and dry use?
Yes. Most slides are designed for wet use in the summer and dry use in cooler seasons. Families often book water slides for summer birthdays, while schools and churches rent dry slides for fall festivals, field days, and winter carnivals.
What ages are best suited for wet/dry slides in Central Texas?
Slides are safe for ages 3 and up. Smaller 12–15 ft models are recommended for younger children, while dual-lane 20+ ft slides are popular with teens and adults.
What do I need for a water slide setup at my home or a park?
A standard garden hose connected to a water source with steady pressure is needed. Our crew installs the misting system. For dry setups, no hose or water connection is required.
How do wet/dry slides stay wet during use?
Slides use a built-in misting hose that sprays water across the sliding surface, keeping it slick and safe. For dry rentals, the hose is disconnected, and the unit is safe for climbing and sliding without water.
Can slides be set up indoors in Austin or San Antonio?
Yes. Dry slides are frequently used indoors at schools, rec centers, and churches, especially in the winter months. Indoor setups require at least 15 ft of ceiling clearance and a wide entrance.
Can wet/dry slides be set up at Austin or San Antonio parks?
Yes. Parks like Zilker Park, Pease Park, and Mueller Lake Park in Austin, and Brackenridge Park, San Pedro Springs Park, and McAllister Park in San Antonio, allow inflatables with permits. Most parks require proof of insurance, which we provide. Generators are available when outlets are not on-site.
How much space is required for a wet/dry slide?
Slides vary, but most need 15–20 ft in width and 25–40 ft in length. Large dual-lane slides may require 40+ ft. Product pages list exact dimensions, and AR previews help confirm fit.
How are slides cleaned and maintained?
Slides are vacuumed, washed with soap and water, and sanitized with EPA-approved disinfectants after each rental. High-touch areas like stairs, handles, and landings are given extra attention.
What safety rules apply to wet/dry slides?
Only one rider per lane at a time, no flips, no roughhousing, and adult supervision at all times. For wet setups, extension cords and blowers must be kept dry.
Can I keep a wet/dry slide overnight?
Yes. Overnight rentals are available. Select “8am pickup” during checkout for next-day pickup. Many schools and churches book slides overnight for multi-day festivals.
What deposit is required for wet/dry slide rentals?
Most rentals require a 50% deposit at booking, with the balance due on event day. For large orders over $1,000 — such as school field days or church carnivals — only a 25% deposit is required.
What is your cancellation and weather policy in Central Texas?
If weather conditions are uncertain, you may cancel before delivery for full store credit that never expires. Once the slide is set up, the rental fee applies. If rain passes during your event, towel-dry the slide and resume use.
Do you carry themed dry/wet water slides in Austin and San Antonio?
Yes. We stock licensed themes like Disney Princesses, Marvel superheroes, Nickelodeon favorites, and Star Wars, along with tropical, castle, and sports-themed designs.
Are there affordable dry/wet water slides in Austin and San Antonio?
Yes. From small backyard slides to giant dual-lane festival slides, we offer rentals for every budget. Visit our Austin Specials Page for the latest deals and seasonal discounts.
What should I do if wind speeds increase during my event?
If wind speeds exceed 15 mph, immediately stop use and turn off the inflatable. Even with stakes or sandbags, inflatables cannot be safely secured in high winds. A good rule of thumb: if you see trees swaying heavily or a storm is approaching, power off the blower until conditions improve.
