The concept of portable toilets can be traced back to World War II, where shipyard workers needed convenient restroom facilities. George Harding, recognizing this need, developed a portable toilet using readily available materials like plywood and metal drums in the 1940s. These early units provided a basic but essential sanitary solution in environments lacking traditional plumbing.
These self-contained units offered significant improvements in sanitation and worker comfort, particularly in construction, large events, and disaster relief scenarios. The ability to easily relocate these facilities proved invaluable, contributing to increased productivity and hygiene standards in diverse settings. Over time, advancements in materials and design have led to more durable, comfortable, and environmentally friendly options.
