- 🎪 Our Story
About Us
We’re a family-run team that turned one beat-up dunk tank and a lot of laughter into Chicago’s loudest, wettest dunk tank rental company.
From One Tank To A Whole Fleet
Jump Guy started the way most good things do — by accident. One rented dunk tank at a neighborhood block party, one very brave uncle on the seat, and a line of kids that didn’t quit until the sun went down.
That afternoon turned into a mission: bring the same soaking-wet, belly-laughing fun to every school, church and backyard in Chicagoland. Today we deliver, fill and set up commercial dunk tanks across the metro — but we still run it like that first block party.

Every tank and seat is cleaned and sanitized before it reaches your event.
Show Up On Time
We arrive early, set up, and test every splash so you start on schedule.
Safety Always
Steel cage, secure seat and a 4-ft rule keep every dunk safe and sound.

Frequently Asked
How much space does a dunk tank need?
Plan for a flat 10×20 ft area with room for a throwing line, plus access to a standard garden hose. We handle the rest.
How is the tank filled?
You supply a garden hose; we position and level the tank, then fill about 500 gallons on-site. It takes one to two hours depending on your water pressure.
Is it safe for kids?
Yes. Throwers of any age can play; anyone sitting the seat must be at least 4 ft tall. The steel cage protects the dunkee and every tank is sanitized before use.
What’s included in delivery?
Delivery, setup, filling, a splash test, three throwing balls, and teardown at the end. You just line up the volunteers.
Do you require a deposit?
Yes, a deposit reserves your date; the balance is due before or on the event day. We confirm the exact amount when you book online.
What if it rains?
If severe weather hits before we dispatch, your deposit becomes a rain check good for twelve months — so your event is never lost.
