The mobile commode industry started in the late 1940s in the shipbuilding lawns of California, Long Beach. During that time, employees used on the ships needed to go to the port each time they needed to utilize a toilet. They were much lighter than timber as well as for this reason caused easy transport. Still, problems really did not finish there. The fiberglass porta-potties called for extra upkeep because of the brittleness of the product.
