We transformed a steel container into a compact, fully-equipped facility, featuring insulated, framed walls with durable FRP overlay and wall-mounted fixtures, including stainless steel sinks. A shower with built-in benches and an ample hot water supply ensures comfort, while concealed plumbing maintains a sleek, clean aesthetic. Energy-efficient LED lighting and effective ventilation enhance the design, creating a durable, functional, and eco-friendly solution that delivers comfort and hygiene for a variety of applications.
