What exactly is inside an ADA-compliant porta potty?

Question

An ADA-compliant portable toilet must meet the 2010 ADA Standards for Accessible Design. It provides a clear interior turning space of at least 60 inches in diameter, compliant door hardware, grab bars, and an accessible toilet seat height.

**Turning space:** The interior must allow a wheelchair to turn completely, either in a circle or a T-shape per ADA section 304. This requires more floor space than a standard unit.

**Grab bars:** There must be a horizontal grab bar on the side wall and a rear grab bar, both mounted at 33 to 36 inches above the floor and able to support 250 pounds.

**Door and hardware:** The door must have a minimum clear opening width of 32 inches when measured at 90 degrees. The latch must be operable with one hand without tight grasping or twisting.

**Toilet seat:** The seat height must be between 17 and 19 inches from the floor to the top of the seat, unlike the higher seat in many standard units.

These units are required by the ADA cluster rule whenever you have a cluster of portable toilets. They are identified with the International Symbol of Accessibility. For your event, verify the unit meets these specs and that the cluster includes at least one ADA unit. If you have questions about placement or specific features, ask below.
