Should I rent flushing porta potties or a restroom trailer for a wedding?
Rent flushing porta potties with sinks when the budget is tight, the ground is uneven or there is no power. Rent a restroom trailer when guests are dressed up, the event runs into the night and you have level ground, a water hose and a standard outlet. Trailers cost more but feel like a real bathroom.

How many restrooms does a wedding with 150 guests need?
A 150-guest wedding of about 5 hours with a bar needs 4 flushing units or one 2-stall restroom trailer plus 1 standard unit. Start with 1 unit per 50 guests for 4 hours, add 1 for the extra hour, then add 1 for every 5 units because alcohol is served.
Worked example: 150 ÷ 50 = 3 units. The bar adds 1 more, so plan 4. For a trailer, each stall covers about 50 guests, so a 2-stall trailer plus 1 standard unit near the dance floor handles the same crowd. If any guest uses a wheelchair, swap one unit for a wheelchair-accessible unit.

What does a restroom trailer need at the venue?
A restroom trailer needs a level spot the truck can back into, a garden hose connection and a standard 110-volt outlet within about 100 feet. No outlet? We can supply a quiet generator. No water? A holding tank can be added. Trailers cannot sit on steep slopes or soft, wet lawns.
Walk the venue before booking: measure the gap between trees or fences, look for low branches, and check the ground after rain. Farm venues around Wentzville, Troy and Washington often have the room but not the outlet, so ask about a generator when you call.

How far ahead should I book wedding restrooms?
Book 2 to 4 weeks ahead for weddings in May, June, September and October, which are the busiest months. Restroom trailers have fewer units, so book them as soon as the date is set.
Can the units be placed out of sight of the ceremony?
Units can go behind a tent, a barn or a row of trees as long as the truck can reach the spot and guests have a clear, lit path.
Do restroom trailers have air conditioning?
Most trailers have climate control that runs on the same power hookup. Ask when you book if the wedding falls in July or August, when St. Louis highs run near 90°F.
Do you supply the toilet paper and soap?
Trailers and flushing units arrive stocked with toilet paper, soap and paper towels. Ask for extra supplies for weddings over 150 guests.
Will someone stay to clean during the reception?
Attendant service is not standard. For long receptions, assign one person to check supplies halfway through and keep extra paper in the trailer.
Is there a unit with a men’s side and a women’s side?
Two-stall restroom trailers have separate entrances, so one side can be signed for men and one for women.
