Everything you need to book, deliver, fill, and run a dunk tank for your next fundraiser, carnival, or backyard bash
- How much does it cost to rent a dunk tank?
- Daily rental rates for dunk tanks on RNTR typically run from $150 to $300 per day depending on size, style, and local availability. Weekend and multi-day rates are often discounted, and delivery fees vary by distance from the provider.
- Does the rental provider deliver and pick up the dunk tank?
- Most providers on RNTR offer delivery for an added fee, and some include it in the rental price. You can also arrange pickup with your own trailer or truck if you want to skip the delivery charge, just confirm the tank fits your vehicle beforehand.
- Who fills and drains the dunk tank?
- In most rentals, filling and draining is the renter's responsibility unless the listing specifies otherwise. Plan for a garden hose and 30-60 minutes of fill time, and have a nearby drain or grassy area approved for water runoff.
- Is a deposit required to rent a dunk tank?
- Yes, providers typically require a security deposit that's refunded after a damage-free return. RNTR bookings are backed by Stripe-secured payments and up to $2,000 in damage protection, so you're covered if something unexpected happens.
- How much space do I need to set up a dunk tank?
- Plan for a flat, level area roughly 10x10 feet for the tank itself, plus additional clearance behind it for the throwing line and spectator space. Always check the specific tank's dimensions on its listing before booking.
- Can I find a dunk tank available near me on short notice?
- Availability depends on your local market and season, with spring and summer being the busiest. Use RNTR's local search guide to check nearby providers and book as early as possible for weekend events.
What You'll Need to Rent for a Dunk Tank Setup
The Dunk Tank Unit
The tank itself is the centerpiece, holding anywhere from 400 to 700 gallons of water with a seat and trigger mechanism that drops the target when a ball hits the pad. Look for a unit like the Big Kahuna Dunk Tank with sturdy wheels for easier positioning and a repaired or fresh vinyl liner to avoid leaks.
Target and Trigger Seat
The seat assembly is what makes the whole game work, so check that the release mechanism is responsive and the seat itself is stable enough for repeated dunking over several hours. A carnival-style dunk tank often comes with a colorful backdrop that adds to the fun for fundraisers and school events.
Water Fill Equipment
You'll need a standard garden hose long enough to reach the tank from your nearest spigot, plus access to a water source that can fill 400+ gallons without straining a well or municipal limit. Some renters bring a second hose to speed up fill time, especially for larger tanks used at all-day events.
Ground Protection and Tarps
A tarp or ground mat under the tank protects grass and prevents mud from splashback, which matters if you're setting up on a lawn you need to return in good condition. This is also worth checking with your provider, since some tanks are collapsible and pack flatter for tighter storage or transport, like a collapsible dunk tank.
Delivery and Transport Accessories
If you're picking up rather than having the provider deliver, you'll need a truck or trailer rated for the tank's weight when empty, plus tie-downs to secure it in transit. Confirm dimensions and weight with the listing before booking so your vehicle is a safe match.
