Long-term rental pricing is available for projects spanning weeks or months, with lower per-day rates than single-event rentals.

Why Contractors Upgrade to Restroom Trailers

The difference between a standard porta potty and a restroom trailer on a job site is significant. Crews who have access to clean, comfortable facilities take shorter breaks and return to work in better spirits. Here is what sets trailers apart.

Climate Control Changes Everything

North Carolina weather is hard on construction crews. Summer temperatures regularly exceed 90 degrees, and winter mornings can drop below freezing. A standard porta potty becomes an oven in July and a freezer in January.

Our restroom trailers are equipped with both air conditioning and heating systems. When a worker steps inside for a break, they get genuine relief from the elements: cool air on a sweltering day or warmth during a cold snap. This is not a luxury; it is a practical tool that keeps your crew comfortable and focused on the job.

Real Plumbing, Real Cleanliness

Every restroom trailer includes:

Flushing toilets that eliminate odor and maintain hygiene
Sinks with running water and soap dispensers for proper handwashing
Interior LED lighting for visibility in all conditions
Non-slip flooring for safety on wet boots
Paper towel dispensers and wastebaskets

Proper handwashing facilities are not just a comfort; they are an OSHA requirement. Restroom trailers meet this standard easily while also reducing the spread of illness on your site.

Professional Appearance for Client Sites

When clients, inspectors, or investors visit your job site, the condition of your facilities says something about your operation. A clean, modern restroom trailer demonstrates professionalism and attention to detail. It signals that you value your crew and maintain high standards across every aspect of your project.

OSHA Compliance and Requirements

The Occupational Safety and Health Administration (OSHA) sets clear standards for sanitation on construction sites. Meeting these requirements protects your workers and shields your company from penalties.

Basic OSHA Restroom Requirements

OSHA Standard 29 CFR 1926.51 requires:

One toilet for every 20 workers on a 40-hour workweek schedule
Facilities must be clean, sanitary, and in good working order
Handwashing facilities must be provided near toilet facilities
Facilities must be reasonably accessible to all workers

ADA Accessibility on Job Sites

If any member of your crew requires accessible facilities, you must provide ADA-compliant restrooms. Our ADA Accessible 3-Station Trailer meets all federal accessibility standards with:

Wheelchair-accessible suite with a 60-inch turning radius
Sturdy grab bars for support
Low-incline entry ramp
Wide doorways (32+ inches)

Providing accessible facilities is not just about compliance; it is about ensuring every member of your team can work with dignity.

Penalty Risks

OSHA violations for inadequate sanitation can result in significant fines. Penalties for serious violations currently exceed $15,000 per instance, and willful violations can climb above $150,000. Investing in proper restroom facilities is far less expensive than a single citation.

Choosing the Right Trailer for Your Job Site

For Small to Mid-Size Crews (Up to 20 Workers)

Our 3-Station Restroom Trailer handles crews up to about 20 workers comfortably. With 2 women’s stations and 1 men’s station, it provides enough capacity for a typical residential or small commercial project.

For Larger Crews (20-40+ Workers)

The 4-Station Restroom Trailer accommodates larger crews with 4 private stalls and separate men’s and women’s entrances. For projects with 40+ workers, multiple trailers can be deployed at strategic locations across the site.

Cost Factors for Construction Rentals

Construction site restroom trailer pricing depends on several variables:

Rental Duration

Daily rentals are priced for short-term projects or site visits
Weekly rentals offer reduced per-day rates for projects lasting 1-4 weeks
Monthly rentals provide the best per-day value for longer projects

Long-term construction projects benefit most from monthly pricing. The per-day rate drops significantly compared to daily or weekly rates.

Delivery and Location

Delivery fees are based on the distance from our headquarters in Apex, NC. Projects in the Triangle region (Raleigh, Durham, Cary, Chapel Hill) have the lowest delivery costs. Sites in Wilmington, Fayetteville, Charlotte, or the mountains involve higher transportation fees.

Site Requirements

Our trailers need:

Level, stable ground: Pavement, gravel pads, or compacted earth
Power source: Standard 110-volt outlet or generator
Water connection: Garden hose hookup or onboard freshwater tank

For remote sites without power or water, we can arrange generator rental and use the trailer’s built-in freshwater system.

What Is Included

Every construction rental includes:

Professional delivery and setup
Full initial stocking (toilet paper, soap, paper towels)
Climate control (AC and heating)
Post-project pickup and waste removal

For multi-week projects, we offer scheduled servicing visits to restock supplies and maintain the units. Contact us for a detailed quote tailored to your project timeline and crew size.

Setup and Placement on Job Sites

Where to Position the Trailer

OSHA requires restroom facilities to be “reasonably accessible” to workers. Best practices include:

Within a 5-minute walk of the main work area
On stable, level ground away from active excavation or heavy equipment paths
Near the site entrance for easy servicing access
Clear of overhead hazards like crane swing areas

Power and Water Options

Most active construction sites have temporary power available. If not, a portable generator runs the trailer’s climate control, lighting, and water pump. For water, a standard garden hose connection is ideal, but our trailers can also operate on their onboard freshwater tanks for remote locations.

Servicing Schedule

For high-use construction sites, we recommend:

Weekly servicing for crews of 10-20 workers
Twice-weekly servicing for crews of 20+ workers
Custom schedules for projects with specific needs
