How many units does a wedding need?
Start from Florida Table PR I, which scales by guest count and duration together, then adjust. The published reference point is 4 units for 1,000 people over 8 hours, so a typical wedding sits well below that.
The adjustment nobody in the code makes for you
Alcohol. Florida rule treats a dry ceremony and an open bar identically, but usage rate does not. Adding 15 to 20 percent above the minimum is the planning convention, and it is the difference between a compliant wedding and one where the queue appears in the photographs.
Duration matters as much as headcount
A six-hour reception generates far more use per guest than a two-hour ceremony with the same attendance. If your timeline runs long, size to the timeline rather than to the invitation list.
Standard units or a trailer?
At a venue with permanent restrooms nearby, standard units covering an overflow or a remote ceremony site are usually enough. At an outdoor or private-property venue where the portable units are the only restrooms, this is the decision guests remember.
A 2-station trailer serves roughly 100 to 150 guests over an evening at $750 to $1,500 for the weekend. The same guest count on standard units runs 3 to 4 units at $150 to $300 each. The gap is real but smaller than the headline prices suggest, and it is the most commonly regretted line when it is cut.
Where do the units go?
Close enough to walk in event shoes, far enough to be out of frame. Those two constraints conflict at almost every venue, and resolving them is worth ten minutes with the planner and the photographer before the order is placed.
The accessible unit needs a real approach
Stable, firm and slip resistant ground, at least 36 inches wide, with slope no steeper than 1:12. Lawn and sand fail that test. Ground protection matting runs $50 to $200 per placement and is the standard fix at Florida outdoor venues.
The service truck needs an approach too
A unit that a vacuum hose cannot reach cannot be serviced, and on a multi-day event Florida requires daily servicing. Agree where the truck parks before you decide where the units sit.
Lighting is usually forgotten
An evening reception means guests walking to the units in the dark. Interior lighting options exist and path lighting is usually the venue's job. Neither happens by default.
When should you book?
Earlier than the unit count justifies, particularly for a trailer or an accessible unit. Both are thin inventory across Florida and both compete with a wedding calendar that runs most of the year.
Standard units can usually be found a week out even in a busy month. A specific trailer configuration a week out in peak season frequently cannot be found at any price. If the trailer is load-bearing for the day, treat it as a venue-level booking made months ahead rather than an equipment line added at the end.

Florida unit counts for special events
Florida Administrative Code 64E-6.0101 Table PR I scales required portable restrooms by expected attendance and event duration. As published examples, a 1,000-person event running 8 hours requires 4 units, and a 10,000-person event running 10 hours requires 30 units.
| Attendance | Event duration | Portable restrooms required |
|---|---|---|
| 1,000 | 8 hours | 4 |
| 10,000 | 10 hours | 30 |
Table PR I is a graduated table across the full range of attendance and duration. The two rows above are published reference points; confirm the exact figure for your attendance and duration against the rule text or with the county health department.

How many portable restrooms must be ADA accessible
Under the 2010 ADA Standards for Accessible Design, where multiple single-user portable toilet units are clustered at one location, at least 5 percent of the units at each cluster must be accessible and identified with the International Symbol of Accessibility.
| Units in the cluster | Minimum accessible units |
|---|---|
| 1 | 1: the single unit must be accessible |
| 2–20 | 1 |
| 21–40 | 2 |
| 41–60 | 3 |
| 61–80 | 4 |
| 81–100 | 5 |
The rule applies per cluster, not per event. An event with four separate restroom banks has four clusters, and each one needs its own accessible unit.

Minimum servicing frequency at special events
Florida requires portable restrooms at special events to be serviced at least daily. On a multi-day event this means service vehicle access has to be planned into the site layout before the units are ordered.

Hand wash station ratio in Florida
Florida requires one hand wash facility for every ten portable restrooms at special events and at remote locations where food is served.

The accessible route to the unit
An accessible portable restroom has to sit on an accessible route. Under the 2010 ADA Standards the ground surface must be stable, firm and slip resistant, the route must be at least 36 inches wide, and running slope may not exceed 1:12.
A compliant unit standing on soft sand, loose turf or gravel does not meet the standard. The unit and the ground it stands on are assessed together.

Frequently asked questions
How many porta potties do I need for a 150 person wedding?
Plan on 3 to 4 standard units for a five to six hour reception with alcohol, or one 2-station restroom trailer. At least one unit in each cluster must be accessible under the 2010 ADA Standards.
How much does a porta potty cost for a wedding in Florida?
Standard units run $150 to $300 for the weekend and deluxe flushing units $200 to $400. A 2-station restroom trailer runs $750 to $1,500, and larger trailers $1,400 to $3,000.
Do wedding porta potties need to be accessible?
At least 5 percent of the units in each cluster, with a minimum of one. If you provide only one unit anywhere, that unit must be accessible, and it needs a firm, stable, slip resistant approach at least 36 inches wide.
Do I need a hand wash station at a wedding?
Florida requires one per ten portable restrooms at special events. Below ten units it is not required, but at $109 to $175 it is the cheapest upgrade available and the one guests notice at a catered event.
How far in advance should I book wedding restrooms?
Months ahead for a trailer or an accessible unit, both of which are thin inventory across Florida. Standard units can usually be arranged within a week outside peak season.
