What is inside a restroom trailer?
A restroom trailer is a towable bathroom with 2 or 4 private stalls. Each stall has a flushing toilet, and the trailer has vanity sinks with running water, mirrors, lights, and a fan and heater for climate control. Guests walk up a few steps into a real-feeling bathroom.
- Flushing toilets in private stalls with locking doors
- Vanity sinks with running water, soap and paper towels
- Mirrors and interior lights for evening events
- Fan and heat for summer heat and cool fall nights
- Exterior steps at each door
The trailer has its own fresh-water and waste tanks. Our crew levels it, connects power and water, and stocks it before guests arrive.
Tech specs: 2-stall vs. 4-stall restroom trailer
Both restroom trailer sizes need a 120-volt, 20-amp outlet within 100 feet, a garden hose or an onboard fresh-water fill, and level ground. A 2-stall trailer fits a spot about 20 by 8 feet. A 4-stall trailer is longer, so dispatch confirms its footprint on the call.
| 2-stall trailer | 4-stall trailer | |
|---|---|---|
| Toilets | 2 flushing stalls | 4 flushing stalls |
| Sinks | Vanity sinks, running water | Vanity sinks, running water |
| Power | 120V, 20-amp outlet within 100 ft | 120V, 20-amp outlet within 100 ft |
| Water | Garden hose or onboard tank fill | Garden hose or onboard tank fill |
| Space | About 20 x 8 ft, level | Longer; confirmed on the call |
| Access | Road or driveway for a pickup towing the trailer | Road or driveway for a pickup towing the trailer |
| Weekend price | From $1,095 | From $1,695 |
Use a dedicated outdoor outlet if you can. A circuit shared with a tent's lights, a caterer's warmers or a DJ can trip the breaker. If no outlet is close, a generator with a 120V, 20-amp output works; tell dispatch ahead of time.
Will a restroom trailer fit on my property?
A restroom trailer needs a level spot about 20 feet by 8 feet that a pickup can back into, plus room to swing the truck. Trailers cannot go through yard gates. Driveways, parking lots and firm, flat lawns work; soft or steep lawns do not.
- Access: clear the route of low branches, wires and parked cars.
- Level: the crew can level a mild slope with jacks, not a steep one.
- Distance: outlet within 100 feet, hose spigot within reach.
- Ground: after heavy rain, a soft lawn can rut. Pavement or gravel is safer.
Text dispatch a photo of the spot. For weddings at farms and barns, walk the route the truck will take. Our porta potty vs. restroom trailer guide helps if you are still deciding.
How many guests can one restroom trailer stall serve?
We count each restroom trailer stall as 1 unit in our event chart: 1 per 50 guests for up to 4 hours, plus 1 per 100 guests for longer events and 1 per 100 if alcohol is served. A 2-stall trailer covers 100 guests for 4 hours without a bar.
| Guests | Up to 4 h | 4-8 h | 4-8 h with bar |
|---|---|---|---|
| 50 | 2-stall | 2-stall | 4-stall |
| 75 | 2-stall | 4-stall | 4-stall |
| 100 | 2-stall | 4-stall | 4-stall |
| 150 | 4-stall | 4-stall + 1 unit | 4-stall + 3 units, or two 4-stall |
| 200 | 4-stall | 4-stall + 2 units | Two 4-stall |
A trailer's larger tanks rarely fill up at a one-day event. The limit is line length at peak times, like after dinner or a toast. Adding a deluxe flushing unit or two near the dance floor shortens lines for less than a bigger trailer.
Public events also need at least 1 wheelchair-accessible unit, since trailers have steps. Run your numbers in the porta potty calculator.
When is a restroom trailer the wrong choice?
A restroom trailer is the wrong choice when no outlet sits within 100 feet, when the only spot is a soft or steep lawn, or when the budget is under about $1,000. A trailer is also wrong as the only restroom for wheelchair users, because every trailer door has steps.
For job sites and backyard parties, standard units do the job at a fraction of the price. For a wedding with no power, deluxe flushing units with sinks give guests a flush and soap without a cord.
A trailer is the right call for formal weddings, corporate events, long outdoor events, and anywhere guests will be in dress clothes for 5 or more hours.
Restroom trailer vs. deluxe flushing porta potties
A 2-stall restroom trailer starts at $1,095 for a weekend, while 2 deluxe flushing porta potties start at $490. The trailer adds running water, mirrors, lights and climate control. The deluxe units need no power or hose and fit spots a trailer cannot reach.

|---|---|---|
| Weekend price | From $1,095 | From $490 ($245 each) |
| Toilets | 2 flushing, private stalls | 2 flushing units |

| Lights and climate | Interior lights, fan and heat | Daylight roof; no power |
| Hookups | 120V outlet and hose | None |

Can restroom trailers be used for emergencies and disasters?
Restroom trailers work well for emergency shelters, water main breaks, flooded buildings and plumbing failures at schools, offices or churches. A shelter runs 24 hours a day, so plan more stalls than an event chart shows and book daily service from day 1.
Tell dispatch the number of people, how many days, and whether building power works. If power is out, the trailer can run from a generator with a 120V, 20-amp output. Pair trailers with hand wash stations and standard units to add capacity fast.
For a single home with a failed septic system, a standard unit delivered same-day is faster and cheaper. Public agencies and churches can send a tax-exempt certificate, and approved accounts can be invoiced monthly.
Common questions
How many restrooms are in a trailer?
Our restroom trailers come in 2-stall and 4-stall sizes. Each stall is a private room with a flushing toilet, and the trailer has vanity sinks with running water.
Does a restroom trailer need electricity and water?
A restroom trailer needs a 120-volt, 20-amp outlet within 100 feet for lights, fans and pumps. Water comes from a garden hose, or we fill the onboard fresh-water tank if no spigot is close.
How many guests does a 2-stall restroom trailer serve?
A 2-stall trailer covers about 100 guests for an event up to 4 hours with no bar. For 4 to 8 hours or a bar, most groups of 75 or more need a 4-stall trailer or extra units.
Can a restroom trailer go on grass?
A restroom trailer can sit on firm, level grass. After heavy rain, a soft lawn can rut under the truck and trailer, so a driveway or gravel pad is safer. Text dispatch a photo of the spot.
Is a restroom trailer wheelchair-accessible?
Our restroom trailers have steps at each door, so they are not wheelchair-accessible. Add a wheelchair-accessible porta potty near the trailer for guests who use a wheelchair or walker.
Can I get bathroom trailers for an emergency shelter today?
Call dispatch at (937) 230-2836 with the headcount, location and power situation. We check trailer and truck availability on the call and back trailers up with standard units and hand wash stations when needed.
Do you pump out a restroom trailer during a long event?
Multi-day events get scheduled service: we pump the waste tank, refill fresh water, clean the stalls and restock supplies. The service schedule and its price are listed on your quote before you book.
How far ahead should I book a wedding trailer?
Book a wedding restroom trailer 1 to 2 weeks ahead for May through October weekends, and earlier for popular Saturdays. Trailers are limited, so reserve as soon as your date and venue are set.
