FAQs for Portable Restrooms on Jobsites

Kerkstra’s construction-ready units are designed to meet OSHA guidelines. Here’s the general recommendation based on crew size:

  • For 20 or fewer workers, your jobsite will need 1 restroom.
  • For 20 or more workers, your jobsite will need 1 toilet and 1 urinal per 40 workers.
  • For 200 or more workers, your jobsite will need 1 toilet and 1 urinal per 50 workers.

Best practice is to place restrooms 75–100 feet from the work area, on stable ground for accessible and compliant facilities. We always recommend that you reference your jobsite and OSHA compliance information to ensure overall worker safety. 

There are several factors to consider before renting portable restrooms for your site. It’s important to understand your project’s requirements, including workforce, timeline, location, and overall environment. Here’s a checklist of questions to ask before renting portable restrooms:

  • How many workers will be on-site?
  • Does my worker-to-restroom ratio align with OSHA requirements?
  • Will units need to be placed on elevated platforms or multi-level buildings?
  • When is the project start date?
  • How long is the project expected to last?
  • On average, how many hours will workers work each week?
  • Will I need additional handwashing stations?

These questions will help determine the rental duration, number of units, establish a routine maintenance schedule, and ensure you choose the right unit type. Have questions or need advice? We can help walk you through recommended options and service plans. 

Yes. OSHA requires that portable restrooms have handwashing facilities available. Kerkstra recommends units with an attached exterior sink for convenience, or, for larger projects or units without attached sinks, a separate handwashing station ensures efficiency and compliance.

Crane rack units are easy-to-lift, accessible restroom solutions for workers on elevated sites, such as high-rise buildings or bridges. On multi-level construction projects, having a restroom nearby is even more essential for efficiency and worker safety. Without one, workers must travel up and down floors, increasing downtime and the risk of accidents. Here are the key characteristics of crane rack units:

  • The arm can be raised or lowered as needed
  • Easy mobility for construction sites
  • Both legs are attached for secure lifting
  • Hand sanitizer included
