One of the most common questions couples ask when planning an outdoor wedding is: how many washrooms do we actually need?
The answer depends on three main factors: guest count, event duration, and alcohol service.
As a general guideline:
-
75–100 guests typically require at least one luxury restroom trailer.
-
150+ guests may require multiple units depending on event length.
-
Events longer than four hours or those with full bar service increase restroom usage.
Luxury restroom trailers are designed to handle higher volumes more efficiently than traditional portable toilets. Multiple private stalls, sinks with running water, and proper lighting help reduce wait times and maintain cleanliness throughout the event.
For weddings in Ottawa and rural venues without permanent facilities, selecting the right size and number of washroom trailers ensures smooth flow and guest comfort. Consulting with your rental provider early in the planning process can help determine exactly what’s needed based on your venue and guest list.
