Portable Restrooms for Weddings

Guest-count math

The number of units depends on guests, hours, and drinks. Longer receptions and an open bar increase use. Planners typically count stalls rather than units, since a restroom trailer may have several stalls. Use our how many porta potties do I need page for the full method, and confirm the recommendation with your provider.

1. Count guests

   Use the final RSVP number plus vendors and staff.

2. Add hours

   Include ceremony, cocktail hour, reception, and cleanup time.

3. Adjust for alcohol

   Plan extra capacity if alcohol is served, especially for long receptions.

4. Add accessible and handwashing capacity

   Include at least one ADA-compliant unit and handwashing near the restrooms.

Standard units, upgraded units, or a trailer

Compare trailers and units in portable toilet vs. restroom trailer.

Power and water for restroom trailers

Many trailers need electricity for lights, fans, pumps, and climate control. Ask your provider what outlet or generator capacity the trailer needs, and confirm the venue can supply it without tripping circuits used by the caterer or band. Some trailers use onboard fresh water tanks, while others can connect to a hose bib. The venue coordinator and provider should talk directly about these details.

• Confirm the power type and distance to the nearest outlet.
• Ask whether a generator is needed and who supplies it.
• Check whether the trailer uses tanks or a water connection.
• Make sure the trailer can be towed to a level spot without damaging lawns.

Placement that works for guests and photos

Restrooms should be easy to find but out of sight lines for the ceremony and portraits. Keep them downwind and away from food service. Provide a lit, firm path for evening use, and consider guest footwear on grass. The provider's truck must reach the spot for delivery and pickup, so walk the site with them in mind.

Attendants and servicing

For larger or longer weddings, some providers offer an attendant who restocks supplies and keeps restrooms tidy during the event. Ask whether this is available in your area. For multi-day celebrations, schedule servicing between days. Plan delivery a day before and pickup the day after so restrooms are never rushed.

Venue and permit questions

Private venues often have rules about where vendors can drive and park. Public parks and some private properties may require permits for temporary restrooms. Ask the venue and check with the city or county. Our portable toilet permits guide explains what to look for.

Questions to ask before you book

A short call with the provider can prevent surprises on the day.

• What delivery and pickup windows are available for the venue?
• How much level space does the trailer or unit group need?
• What power, water, and generator arrangements are required?
• Is an attendant available, and for how many hours?
• What supplies are included, and can extra be left on site?
• Who should the venue coordinator contact on the day of the event?
