Local tip for St. Louis

If you’re planning an event in a St. Louis City park like Tower Grove or Carondelet, definitely check with the Parks Department early about permit requirements for inflatables and water features. Many require specific forms and advance notice, which can impact your delivery and setup.

Delivery in St. Louis

Our team navigates the unique streets of the Lou with ease. We’re accustomed to a mix of tight residential streets and wide suburban boulevards. Please let us know ahead of time about any challenging access points like narrow gates, steep inclines, or if your event is on a multi-level property.

St. Louis event seasons

Dunk tank rentals are most popular from late spring through early fall, from May to September, when that famous St. Louis humidity truly kicks in. We recommend booking early for June-August events, especially around holidays like the Fourth of July, as demand is high to beat the heat.

Why book locally

Booking with a local St. Louis operator means you get personalized service from folks who know our neighborhoods, parks, and event venues inside and out. We understand local traffic patterns to ensure on-time delivery and provide responsive, day-of support, something an out-of-town company simply can’t match.

Dunk Tank Rentals in St. Louis — FAQ

Do I need a permit for a dunk tank in a St. Louis City park?

Yes, St. Louis City Parks often require special event permits for dunk tanks and other large equipment. It's best to confirm with their office when reserving your pavilion.

What kind of water hookup do I need for a dunk tank?

A standard garden hose connection with good water pressure is all that's typically needed for filling. We recommend having access to a spigot within 75 feet of the setup area.

Can you set up a dunk tank on uneven ground?

For safety, dunk tanks require a relatively flat and level surface. Please inform us if your proposed setup area has significant slopes or uneven terrain.

How much does a dunk tank cost?

Most dunk tank rentals run $250–$450 per day plus delivery, depending on city and weekend demand.

How is it filled?

A standard garden hose fills the tank in 30–45 minutes. Some operators offer a fast-fill option.

Where can I drain it?

Operators provide a drain hose. Drain to a lawn, alleyway, or storm-safe area — most cities allow it.
