Wedding Restroom Calculator

How the calculator works

The wedding calculator uses the same math our dispatchers run on the phone:

• Guest count + alcohol drives the base unit count. With alcohol, bathroom use roughly doubles. Without, the standard 1-per-50 ratio holds.
• Event length bumps the count for events over 4 hours.
• Formality determines tier — black-tie weddings need climate-controlled trailers, casual backyard weddings can use deluxe porta potties.
• Weather adds A/C requirements above 85°F or heating below 50°F.
• Venue type determines whether you need a full restroom solution or just supplemental capacity.

For the deeper breakdown of why these inputs matter, read our wedding restroom decision guide or the head-to-head porta potty vs restroom trailer comparison.
