Delivery in Denver
Our team navigates Denver traffic daily, from the I-25 corridor to neighborhood streets. Please ensure clear access, as steep inclines or multiple gates can impact setup time. We typically need a relatively flat, grassy area for safe setup.
Denver event seasons

Waterslide Rentals in Denver — FAQ
Do I need a permit for a waterslide at a Denver city park?
Yes, Denver Parks and Recreation typically requires a permit for inflatables. It's best to confirm with the specific park office or their special events division.
What kind of power and water hookups do I need?
Our waterslides require standard 120V outlets, usually one per blower. You'll also need a garden hose within 50-100 feet of the setup area for continuous water supply.
Can you set up a waterslide on concrete or asphalt?
For safety and structural integrity, our waterslides are primarily designed for setup on grass or other soft, permeable surfaces. We can sometimes accommodate other surfaces with proper padding, but please inquire beforehand.
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.
