Booking Porta Potties for a Wedding
The unit is the easy part. What catches people out is the ground it stands on, the power it needs, and how far ahead trailers actually book.
Book the trailer before the venue is final
Restroom trailers are a small fraction of any market's fleet, because a trailer is real capital for a yard that mostly rents standard units. In most markets they are gone a season ahead. If the trailer matters to you, it is the booking that should drive your date rather than the other way round.
What the site has to provide
A level pad, a route in that a truck can tow through, and usually a power hookup. Some models need a water connection as well. A field that looks fine in June is a different proposition after a wet week, so ask the company what they need on firm ground and settle it early.
The ADA unit people forget
If the day is open to guests you have not personally vetted for mobility — which is every wedding — you want at least one accessible unit. It needs a firm, level approach, not just the unit itself. A beautiful trailer at the top of three steps is not accessible.
Count for the whole day, not the ceremony
One unit per 50 guests over four hours is the starting ratio. A wedding runs longer than four hours and serves alcohol, so add 15 to 20% and round up. Nobody has ever regretted one extra unit.
