Delivery in San Jose
Our San Jose delivery team is familiar with the area's diverse terrain, from hillside homes to suburban cul-de-sacs. Please note any challenging access points like steep driveways, narrow gates, or stairs when booking, as well as if you're in an HOA that requires advance notice for large deliveries.
San Jose event seasons
The prime waterslide season in our area runs from May through September, peaking during the warm summer months. While we enjoy mild winters, outdoor events requiring waterslides are generally limited to the drier, warmer half of the year. Booking spring and early fall dates early is always a good idea!

Waterslide Rentals in San Jose — FAQ
Do I need a permit for a waterslide at a San Jose park?
Yes, city parks generally require a special use permit for large inflatables. We advise checking with the San Jose Parks and Recreation Department for specific requirements and application processes.
What are the power requirements?
Most waterslides require a standard 120V outlet on a dedicated circuit. If your event location doesn't have sufficient power, we can provide generator rental options.
Do you need a water hookup?
Yes, all our waterslides require a standard garden hose connection. Please ensure a working spigot is accessible within 50-100 feet of the setup area.
How much does a waterslide rental cost?
Backyard waterslides typically run $250–$500 per day. Giant dual-lane or tropical slides range $450–$900 depending on size and city.
Do I need a special hose or water source?
A standard garden hose hookup is all most slides need. Operators bring the splash mat, blower, and stakes.
What surface do I need?
Flat grass is ideal. Driveways and pads work with sandbag anchors — your operator will confirm at booking.
