Construction sites are complex operations. Between managing schedules, safety protocols, and machinery, it’s easy for basic needs to fall off the radar. But when it comes to restroom regulations, there’s no room for shortcuts.

The Occupational Safety and Health Administration (OSHA) sets clear standards around sanitation—and for good reason. A well-maintained, accessible restroom setup directly impacts worker health, morale, and productivity. At A Royal Flush, we’ve worked with construction teams across Texas who understand the value of a clean, reliable restroom setup. Whether you’re using standard units or full restroom trailers, staying compliant keeps your team—and your project—on track.

What OSHA Says About Restroom Regulations

OSHA’s standards for sanitation (29 CFR 1926.51) are very clear: all workers must have prompt access to clean, working toilets. These regulations aren’t just guidelines—they’re legally enforceable. And failing to follow them can lead to penalties, project delays, or worse, a health issue on site.

Basic OSHA restroom regulations include:

• Toilets must be “readily accessible.”

• Facilities must be sanitary and stocked with toilet paper.

• Handwashing stations must be available when workers are exposed to hazardous materials.

• There must be a sufficient number of toilets based on crew size.

Let’s take a closer look at that last one—it matters more than most people realize.

How Many Toilets Do You Need?

According to OSHA’s restroom regulations, the number of toilets you need depends on the size of your crew. For sites with 20 or fewer workers, you’re required to provide at least one toilet. If your site has between 21 and 199 workers, you’ll need one toilet for every 40 employees. For larger crews of 200 workers or more, that increases to one toilet for every 20 employees.

Let’s say you’re managing a project with 60 people on-site—you’d need a minimum of two toilets to stay compliant. But if your crew grows, or if you’re running multiple shifts, that number may need to increase. In those cases, upgrading to restroom trailers can help you meet regulations more efficiently, offering multiple stalls within a single unit and a much more comfortable experience overall.

Hygiene Isn’t Optional—It’s the Standard

Restrooms must be cleaned regularly and maintained in a sanitary condition. That means no overflowing tanks, no out-of-order locks, and definitely no missing toilet paper. On top of that, handwashing facilities (with soap and water) should be available, especially when workers are handling toxic or hazardous materials.

Best practices include:

• Servicing units at least once per week (more often for larger crews)

• Stocking with toilet paper, hand soap, and paper towels

• Providing separate handwashing stations if not included in the unit

• Ensuring all waste is properly contained and removed

Poor sanitation leads to poor morale. And when people are uncomfortable, they’re less focused, less efficient, and more likely to get sick.

Restroom Trailers vs. Standard Units

While standard portable toilets may meet OSHA requirements, restroom trailers take the experience to a whole new level. Especially on long-term or higher-end job sites, restroom trailers show your crew (and your clients) that you’re invested in doing things right.

Benefits of restroom trailers include:

• Flushing toilets and running water

• Sinks with soap and full vanities

• Heating and cooling systems

• Durable interiors built for heavy use

• Private stalls for comfort and privacy

They’re also easier to clean and maintain—meaning fewer headaches for site supervisors.

ADA Compliance on Construction Sites

Construction sites must also provide accessible restrooms for employees with disabilities. An ADA-compliant portable restroom or trailer is larger, includes a ramp, and features handrails and accessible layout. This isn’t just a nice-to-have. It’s part of creating a safe, compliant, and inclusive work environment.

Real-World Tips for Staying Compliant

We’ve worked with enough job sites to know that good intentions don’t always equal execution. So here’s how to make sure your site is meeting all restroom regulations from day one:

• Evaluate crew size and shifts to determine how many units you’ll need.

• Map restroom placement for easy access across the site.

• Choose the right mix of standard units and restroom trailers for comfort and efficiency.

• Set a servicing schedule—and stick to it.

• Work with a vendor (like A Royal Flush!) who understands OSHA requirements and helps you stay ahead of issues.
