Restroom Trailer Manufacturer

Our Portable Trailer Manufacturing Process

The Beginning

When Lang Specialty Trailers started our goal was to create restroom and shower trailers that were durable, elegant, and easy for the operator to use and maintain.  We spent years testing restroom trailers built out of different materials in our rental fleet before finding the materials that stood up to the harsh conditions  that public events, construction use, and special event rentals put them through.  These materials are what are used in every restroom and shower trailer we build today.

The Materials

We have designed our restroom trailers and shower trailers from the ground up to be durable. All of our trailers are built with a heavy duty steel frame, oversized axles, fresh water tank surround, AC unit with heat strip, and  poly propylene waste tank (if equipped).  But what really set us apart from the competition is our composite roof, ceiling, and interior / exterior wall panels.  The composite is seamless and allows for the interior and exterior of the trailer to be one and serve as the structure of the trailer. This design makes our trailers incredibly durable (video link of us hitting the trailer with a sledge hammer).  The composite is also a slick surface that repels dirt and makes for easy cleaning.   


As a restroom trailer manufacturer and shower trailer manufacturer, we ensure all trailers are carefully built by our team of skilled craftsmen.  To ensure the quality of each trailer we produce is up to our standards, each trailer is built in assembly line format with a checklist to create easily repeatable steps.  Once a trailer is complete it goes through rigorous to make sure all components of the trailer are functioning as they should.

Our Facility

Our trailer manufacturing facility is located in Latrobe Pennsylvania.  Though our trailers are produced in Pennsylvania we build and then ship trailers to customers all over the world.  Facility tours for current and potential customers are available by appointment.
