What is the total water capacity of your plunges?

Ultimate Plunge and Ultimate Lite

Maximum water capacity of 90 gallons.

Ultimate Party Plunge

310 to 315 gallons to the max fill line, or 580 gallons to the top of the plunge.

The Ultimate Party Plunge is usually chilled with ice rather than a chiller. How much ice you need depends on the ambient temperature, how many people are using it, and how cold you want the water. As a rule of thumb, allow around 400 lb of ice per hour of your event to hold the water between 32 and 40 degrees. That will also affect how much water you fill it with.
