Rules of Thumb

  • The standard baseline is one portable toilet for every fifty people over a four-hour span.
  • If alcohol is served, you will need to increase the unit count by 10 to 20 percent.
  • For events spanning multiple days, you must factor in regular pump and cleaning services to keep the math accurate.

ADA Accessibility

  • Federal guidelines require at least one wheelchair-accessible unit per cluster of standard units.
  • These units offer more interior space and ground-level entry points for mobility devices.
  • Our AI booking agent automatically adds the proper ratio of ADA units to your order.
