From Public Loos to AI’s Smart Havens The humble public toilet, a cornerstone of urban infrastructure since the Victorian era, is undergoing a radical transformation. For centuries, these often-overlooked facilities have served a basic, essential human need. Yet, their design and functionality have remained remarkably stagnant, often associated with a lack of hygiene, poor maintenance, and a general sense of disrepair.
