How Much Is a Water Slide Rental for a Birthday Party?
A water slide rental for a kids' birthday party costs $219–$345 a day for most parties — a backyard slide or combo that suits kids from about 4 to 10. Toddler parties start at $149, and teen parties with a 26–28 ft giant run $399–$550. Every booking includes delivery, setup, takedown, sanitizing and insurance. Rates as of September 2026.
The biggest factor in the price isn't how many guests are coming — it's how old they are. Pick the slide that fits the birthday kid and their friends, and the budget sorts itself out.

Bounce houses start at $159 with the Pink Palace Bouncer.

The sweet spot. The Sunset Splash 16 and Fiesta Splash 16 are our lowest-priced full-size slides at $219. The Aqua Wave 15 ($259) and Tropical Wave 18 ($269) add a little more height, and the Castle Splash Combo ($289) adds a bounce area for mixed ages.
Birthdays for 8- to 12-year-olds: $319–$369
Older kids want height and racing. Tall 18 ft slides like the Coral Reef 18 run $319, the two-lane Fire & Ice Racer 18 is $329, and the Double Drop Racer 22 — 22 ft tall and rated 6+ — is $369 and takes 8 riders at a time.
Teen parties and big crowds: $399–$550

What's included in the price?
Every booking includes:
- Delivery to your address.
- Professional setup and anchoring by our crew.
- Takedown and pickup when the party wraps.
- A cleaned and sanitized unit.
- Full insurance.
Your written quote confirms the final total for your address and date, so the number you plan around is the number you pay.
What can add to the cost?
- A second unit. A popular birthday setup is a toddler slide or bounce house for the little ones plus a bigger slide for the older kids.
- Add-ons, priced individually: a generator if there's no outlet within reach, a canopy, or an on-site attendant from our event staffing team. See do water slide rentals need a generator?
- Longer rentals. Keeping the slide more than a day costs more — see how long you can rent a water slide.
Is a combo or a water slide better value for a birthday?
It depends on the ages. A combo ($269–$345) gives you a bounce area, slide and splash pool in one unit rated 3+, so toddler siblings and 8-year-olds both have something to do. A straight water slide at a similar price gives older kids more height. Our combo bounce house vs. water slide guide compares them side by side.
