How Big of a Restroom Trailer Do I Need?
When planning an event, a construction project, or an outdoor gathering, part of the logistics involves the need for restrooms. In addition, carefully selecting the size of your restroom trailer rental is essential to hitting the right balance between comfort, efficiency, and an optimal experience for your guests or employees.
Now, how do you know what size you need?
In this guide, we’ll cover the important elements to consider for everything from a luxury portable bathroom rental, portable shower rental, or shower trailer rental for your unique needs—and how to decide the best option for you.
Factors to Consider When Choosing a Restroom Trailer Size
1. Number of Guests or Workers
The most important factor in deciding the size and type of unit needed is the number of people who will be using your restroom trailer rental. The right size helps you stay comfortable, minimizes waiting time, and avoids sanitation problems.
General Guidelines for Different Event Sizes:
- Small Gatherings (Up to 50 People)
A two-stall restroom trailer typically does the trick for small events such as backyard parties, small weddings, or corporate affairs. Usually, these trailers have distinct sections for men and women, with one ceramic flushing toilet, sink, and mirror for each section. They fit in tight spaces, ensuring you get an upgraded restroom experience at your small- to mid-sized event. - Medium-Sized Events (50-150 People)
A 3-4 stall restroom trailer is a good choice for a larger event, like a wedding, festival, or company retreat. With these trailers, it serves more individuals at once, and you do not have those lengthy lines. They could also include more features such as air conditioning, better counter space, and interior illuminated with lights, making it ideal for air-conditioned events. - Large Events (150+ People)
For large-scale gatherings, such as concerts, fairs, sporting events, or conventions, a 6 to 10 stall restroom trailer is ideal. These larger units help keep the lines moving efficiently and prevent overcrowding in restroom areas. Additionally, they may include multiple sinks, mirrors, and even vanity areas to provide an upscale restroom experience.
Considerations for Construction Sites
For construction sites, the number of workers and the duration of your project are essential in deciding what size restroom trailer you need. Unlike social activities, where potty use is infrequent, workers will be counting on these facilities throughout their work day.
- 2-3 stall restroom trailer should be sufficient for small crews (10 to 20 workers)
- For medium crews (20–50 workers), you can choose 4 to 6 stall units
- For a higher number of workers (50+ employees), the optimal solution for a busy job site is a 6 to 10-stall trailer.
If the project is long-term or involves overnight shifts, adding a shower trailer rental is an excellent option to maintain hygiene and boost worker morale. Some portable shower rentals also come with integrated restroom facilities, offering a comprehensive sanitation solution.
2. Duration of the Event or Project
Short events (a few hours) may require fewer stalls, but if your event lasts all day or multiple days, you’ll need more facilities to accommodate higher usage. Portable shower rental options are also recommended for multi-day festivals or remote job sites where hygiene is essential.
3. Luxury vs. Basic Amenities
Are you hosting a formal wedding, corporate event, or VIP gathering? Then, a luxury portable bathroom rental with high-end finishes, climate control, and premium fixtures will elevate the experience. On the other hand, construction projects or casual outdoor events might require a more basic restroom trailer setup.
4. Space Availability
Restroom trailers come in various sizes, and you’ll need to ensure that the designated space at your event site can accommodate the unit. Consider:
- Trailer length and width – Some luxury models are larger due to added features.
- Access for delivery – Ensure the truck delivering your restroom trailer rental can easily maneuver into place.
- Power and water hookups: Some trailers require access to utilities, while others are self-contained.
Portable Bathroom Rental Trailer Size Options
The restroom trailer size plays a crucial role in ensuring a comfortable and efficient experience for guests or workers. Choosing the right size depends on factors such as the number of attendees, event duration, and the level of luxury required.
1. Small Restroom Trailers (2-3 Stalls)
Small restroom trailers with 2-3 stalls are ideal for intimate gatherings like small weddings, family reunions, or boutique events. Their compact design allows them to fit easily in limited spaces while still providing essential facilities. These trailers typically include flushing toilets, sinks, and basic climate control to enhance user comfort.
2. Mid-Sized Restroom Trailers (4-6 Stalls)
Mid-sized restroom trailers with 4-6 stalls work well for corporate events, festivals, and mid-sized gatherings. They are designed with separate sections for men and women, ensuring privacy and better traffic flow. Many mid-sized trailers come with upscale features such as hardwood floors, LED lighting, and air conditioning, creating a more refined experience for guests.
3. Large Restroom Trailers (8-10+ Stalls)
Available in 8–10 or greater stalls and are ideal for high-traffic events such as concerts, sporting events or large weddings. With plenty of sinks, mirrors, and interior room to handle heavy use, these trailers are designed for efficiency. The size of the design is great for reducing waiting time in restrooms and, thus, is a perfect fit for functions or events where convenience takes precedence.
Additional Considerations for Portable Shower and Restroom Trailer Rentals
If your event or job site requires shower facilities, a portable shower rental or shower trailer rental may be necessary. These trailers are available in multiple configurations, including:
- Standalone shower units for personal hygiene.
- Combination restroom and shower trailers for convenience.
- ADA-compliant units for accessibility needs.
