Porta Potty or Restroom Trailer for Your Wedding?
Both work. The right one depends on guest count, power, the ground and how formal the night is.

Which is better for a wedding, porta potties or a trailer?
A restroom trailer is better for weddings with 75 or more guests, formal dress, older guests, or receptions that run after dark. Deluxe flushing porta potties are better for smaller weddings, sites with no power, and fields a towed trailer cannot reach. Standard units suit casual daytime parties only.
| Deluxe flushing units | 2-stall restroom trailer | |
|---|---|---|
| Feel | Clean, single room, flush and sink | Indoor bathroom: tile, mirrors, lights, A/C |
| Guests | About 25 to 30 each for a 5-hour bar reception | About 100 to 130 per trailer |
| Power | None | 110V outlet or generator |
| Water | None | Hose or onboard tank |
| Ground | Any firm, level spot | Level pad with tow access |
| Typical 2026 price | About $280 to $500 each | About $1,500 to $2,500 |
How many restroom units does a wedding need?
A 100-guest, 5-hour wedding with a bar needs 4 deluxe units or one 2-stall restroom trailer. A 150-guest wedding needs about 7 deluxe units or a 2-stall trailer plus 1 deluxe unit. Include 1 wheelchair-accessible unit for any guest who needs it, because trailers have steps.
| Guests | 4 hours | 8 hours | 4 hours, with alcohol | 8 hours, with alcohol |
|---|---|---|---|---|
| 50 guests | 1 | 2 | 2 | 3 |
| 100 guests | 2 | 3 | 3 | 4 |
| 150 guests | 3 | 5 | 4 | 7 |
| 200 guests | 4 | 6 | 5 | 8 |
What do barn and winery venues need to check?
Barn and winery venues need to confirm a level spot reachable by a truck, an outlet on its own 20-amp circuit within about 100 feet for a trailer, and a lit path from the tables. Hilltop wineries near Augusta and Defiance often place trailers by the parking lot and units on the flattest lawn.
Quick answers
Is a trailer worth the cost for 60 guests?
For 60 guests, 2 to 3 deluxe units usually cost less and work as well. A trailer makes sense at that size for a formal or evening event.
Can we mix a trailer and porta potties?
A trailer plus a deluxe or accessible unit is a common setup for 150+ guests.
How early should we book?
Trailers: 1 to 3 months ahead for spring and fall Saturdays. Deluxe units: 3 to 6 weeks.
