Many cities provide indoor and outdoor pool rentals for parties at their recreational facilities. Also, membership-based pools and public water parks allow party rentals. In some cases, the organizations provide access to party rooms and pavilions based on available space and customer preference.

In many cases, there is a minimum fee to rent space for a minimum period of time, such as two or three hours. Customers can arrange longer rental times by paying additional money. Policies also vary with regard to outside food. While most places allow customers to bring in their own birthday cake, cupcakes or other treats, policies about soft drinks, pizza, hot dogs and other types of food vary. Some places allow customers to bring in whatever refreshments they want.

Pool rentals are available on a first-come, first-serve basis. However, even if there is no rental booked for a particular day, most facilities do not permit parties without a prior notice period. For example, Arlington, Texas, requires 72 hours of notice for scheduling a party. It's important to contact the staff at the pool that you want to rent several weeks, or even a few months, ahead of the party date to ensure availability and to learn policies and requirements.
