Porta Potty vs Restroom Trailer: What You Are Actually Paying For
The short answer
A restroom trailer buys guest experience, not capacity. In Georgia, a two-stall trailer runs $650 to $1,400 per event weekend and gives you two usable fixtures, where three standard porta potties would cost $360 to $780 and give you three. Choose the trailer when the experience is the point, and units when the count is the point.
$163
cost per stall at the low end of an eight-stall trailer, which lands inside the $120 to $260 range for a single standard porta potty
Georgia market ranges, compiled 21 August 2026
What we found
Cost per usable stall falls fast as trailer size rises, and at eight stalls a trailer overlaps standard porta potty pricing per fixture.
Method: We divided the published Georgia market ranges for each unit type by the number of usable fixtures it provides, using the same price data published on our cost guides and compiled on 21 August 2026.
| Unit | Weekend price | Usable stalls | Cost per stall |
|---|---|---|---|
| Standard porta potty | $120 to $260 | 1 | $120 to $260 |
| Deluxe flushing unit | $175 to $375 | 1 | $175 to $375 |
| ADA accessible unit | $175 to $400 | 1 | $175 to $400 |
| Restroom trailer, 2 stall | $650 to $1,400 | 2 | $325 to $700 |
| Restroom trailer, 4 stall | $1,300 to $3,500 | 4 | $325 to $875 |
| Restroom trailer, 8 stall | $1,300 to $3,500 | 8 | $163 to $438 |
The premium is real at two stalls and mostly disappears at eight. If you need a high fixture count and the venue can take a large trailer, the trailer stops being the expensive option on a per-stall basis.
What is the actual difference between the two?
One is a self-contained booth with a chemical tank. The other is a towed room with plumbing, and it needs things from your site that the booth does not.
A standard porta potty is a non-flush chemical toilet: a 60 to 70 gallon tank, a vent, a latch, and no hookups of any kind. It goes anywhere a delivery truck can reach and needs nothing from the venue except firm, level ground.
A restroom trailer is a towable unit with flushing porcelain toilets, running-water sinks, interior lighting, climate control, and finished surfaces. It carries its own fresh and waste tanks sized to the stall count, so a permanent water connection is often unnecessary. Power usually is not optional, and a generator adds $150 to $400 per event where the venue has none.
Between the two sits a deluxe flushing unit: a single booth with a foot-pump flush and an onboard sink, needing no hookups at all. It is the answer when a standard unit will not do but a trailer will not fit, which describes a large share of Georgia backyard weddings.
Which one does Georgia's unit table count?
Fixtures, not vehicles. A two-stall trailer counts as two units toward your required number, not one, and this is the detail that changes the budget.
Georgia's special event planning table gives a required number of portable sanitation units for a given peak crowd and duration. A trailer with four stalls supplies four fixtures against that requirement. Treating the trailer as a single unit is the most common sizing error we see on wedding and corporate event plans, and it produces an order that is short by three or more.
This cuts the other way too, and in your favour. A planner who has been quoted a trailer plus a row of standard units may be double-counting capacity they already have. Run the required number first, then decide how to supply it.
The same table instruction applies regardless of unit type: subtract one for each sewered toilet already available on site, and add 25% to the base number if alcoholic beverages are served.
What does a trailer need that a porta potty does not?
A level pad, a tow route, and usually power. Any one of these can rule a trailer out at a venue that looks perfectly suitable on a walk-through.
The trailer is 16 to 30 feet of towable vehicle. It needs a route in wide enough for the tow vehicle, room to manoeuvre and unhitch, and a parking pad level enough for the plumbing to drain correctly. Sloped driveways, soft ground, tight in-town lots, and low overhead clearances rule out larger models more often than the trailer footprint itself does.
In Georgia the ground condition deserves specific attention. Coastal venues around Savannah and Brunswick sit on sandy and marsh-adjacent soil that does not carry point loads well. Middle Georgia festival grounds like Central City Park in Macon sit in a river floodplain. A pad that is fine in August may not be in March.
Standard units have none of these constraints, which is why they remain the default even at events where the budget could stretch to a trailer.
- Level parking pad and a tow route with adequate width and clearance
- Power connection, or a generator at $150 to $400 per event
- Firm ground that will not settle under a loaded trailer
- Delivery, setup, and levelling, normally included in the quoted price
- An attendant at $30 to $60 per hour, if you want the interior maintained through a long event
When should you choose each one?
Choose by what the restroom has to do at your event, not by the size of the budget. Three clear cases cover most decisions.
Take the trailer when guests are dressed for the occasion and the restroom is part of the experience: weddings, corporate hospitality, donor events, film productions. A guest in formalwear in a plastic booth is a memory you paid for.
Take standard units when the count is the point. Festivals, races, county fairs, and construction sites need fixtures distributed across a footprint. Twenty standard units placed where people actually are will outperform two trailers parked where the tow vehicle could reach.
Take the hybrid when both are true. One trailer near the reception or hospitality area, standard units at the far edges of the site. This is the normal answer for weddings between about 100 and 300 guests, and it is what we recommend most often, because it puts the money where guests will notice it and the capacity where it is needed.
Our position
If a trailer would consume more than about a third of your total rental budget and you are still short on fixture count, buy the count first. A queue ruins an event faster than a plastic door does.
How far ahead do you need to book a trailer in Georgia?
Four to eight weeks minimum, and longer for peak Saturdays. Trailer fleets are much smaller than standard unit fleets, so a late request comes back unavailable rather than merely expensive.
Spring and fall Saturdays are the tightest weekends on the Georgia event calendar in both metro Atlanta and Savannah. Accessible units and trailers are the first two categories to sell out, in that order.
Two regional windows are worth planning around explicitly. Savannah's St. Patrick's Day commits Coastal Health District inventory months in advance, and Masters week in Augusta each April pulls units, trailers, and service crews in from across the Southeast, which tightens supply well beyond Richmond County.
Standard units are far more forgiving. One to three business days is normal statewide, and same-day placement is common in metro Atlanta for requests before noon.
Frequently asked questions

Event planners, wedding couples, and venue managers choosing between unit types on a fixed budget.
Call (470) 431-3553Is a restroom trailer worth it for a 150-guest wedding?
It depends on what you want the money to buy. For 150 guests over six hours, Georgia's table scaled down suggests roughly two to three fixtures before the alcohol adjustment, which two or three standard units satisfy for $360 to $780. A two-stall trailer costs $650 to $1,400 and buys a better guest experience, not more capacity.
Does a restroom trailer need electricity?
Most models do. Where the venue has no power, generator rental runs $150 to $400 per event and should be quoted at the same time as the trailer. Trailers carry onboard fresh and waste tanks sized to the stall count, so a permanent water connection is frequently unnecessary.
How many stalls does a restroom trailer have?
Two-stall units are the smallest common configuration, with four to eight stalls typical for larger events. Multi-stall models often have separate entries for men and women. Each stall counts as one unit toward the number Georgia's planning table requires.
Can you put a restroom trailer on grass?
Only if the ground is firm and level enough to keep the trailer stable and let the plumbing drain. Soft turf, sandy coastal soil, and floodplain ground are the common failure cases in Georgia. Walk the route and the pad with the provider before the event, and have a wet-weather alternative.
What is a deluxe flushing porta potty, and where does it fit?
It is a single self-contained booth with a foot-pump flush and an onboard sink, needing no power, water, or level pad. At $175 to $375 per weekend it sits between a standard unit and a trailer, and it is usually the right answer for a backyard wedding where a trailer cannot physically reach the site.
