One of Backyard Party Rentals most fun-filled items is our dunk tank! Test your accuracy by throwing a ball at the target and dunking your boss at the next corporate event. Or rent it for your next block party and dunk that neighbor that always is keeping a nicer lawn than you. No matter the event, you can never go wrong with our dunk tank! If going in a fenced in area, there must be a 6 foot opening for clearance. The tank takes about 45 min to an hour to fill, but we will set it up plenty early to allow fill time.
