The principal aim of this study was to map and describe the availability of parkland public toilets in major US cities per population and area. Observational and descriptive. Data were collected from the following cities: Austin, Texas; Minneapolis-St Paul (MSP), Minnesota; Nashville, Tennessee; New York City (NYC), New York; Philadelphia, Pennsylvania; San Francisco, California (SFC); Seattle, Washington; and Tampa, Florida. These cities are located throughout the United States. Data from the US Census and cities' parks/recreation departments about publicly owned and operated permanent toilet facilities were analyzed and then mapped using geographic information systems. Toilet density by population and residential area (mi) was calculated, and toilet distribution was visualized. When calculated per 100,000 residents, MSP had the most parkland public toilets with 24; Tampa, Seattle, and Philadelphia had 17 to 22; and Nashville, NYC, and SFC had the fewest, around 7 toilets. Parkland public toilet density per residential area was highest in NYC and Philadelphia (>2/mi), followed by MSP, Seattle, and SFC (1/mi), then Tampa, Austin, and Nashville (<1/mi). The proportion of Census tracts containing parkland public toilets was more than 0.4 in MSP, Seattle, Tampa, and Philadelphia, more than 0.20 in Nashville and Austin, and less than 0.20 in the other cities. Toilet mapping showed fairly even distribution across Census tracts in MSP, Seattle, Tampa, and Philadelphia. Availability of parkland public toilets was highest in MSP and lowest in SFC. Findings inform WOC nurses for counseling incontinent patients about self-management strategies. Urban planning that provides an adequate number and distribution of parkland public toilets may improve quality of life.
