Portable Toilet Rental Calculator
Estimate how many portable toilets and handwashing stations to plan for. This is a planning aid, and we will confirm the final numbers with you.
Planning estimate only. Venue rules, permits and workplace regulations may require different numbers. Verify requirements with the authority that applies to you.
Using your estimate
Treat the result as a conversation starter. Real events rarely match a formula: guests may arrive in waves, a nearby building may offer restrooms, or a venue may require a minimum number of units. Likewise, a job site with long shifts in extreme heat may justify more units than the minimum ratio.
When you contact us, include the estimate along with your venue, dates and access notes, and we will help you refine it. If you are planning a wedding, read our wedding restroom guide. For job sites, see construction rentals.
