Access to hygienic sanitation facilities remains a major challenge in developing nations, particularly in rural areas, slums, and temporary settlements. Conventional toilets require permanent construction, high costs, and long installation time, making them unsuitable for rapid deployment. This paper presents the design and development of a ferrocement detachable toilet unit as a cost-effective, durable, and portable sanitation solution. The unit is fabricated using thin ferrocement panels reinforced with wire mesh, which are lightweight yet strong. The system is designed for easy assembly, disassembly, and relocation, making it highly suitable for construction sites, disaster relief camps, and rural sanitation programs. The study highlights the design methodology, material selection, structural performance, cost-effectiveness, and future applications of this innovation.
