In this episode of Waterfall, Mike is joined by Professor Benjamin Gardner from the University of Surrey to explore how smart shower technology is reshaping our understanding of everyday water use. Ben shares insights from a major research project that used sensor-based timers in student accommodation to track shower habits, reveal what drives long showers, and show how simple feedback can cut shower times by up to 43 percent. Together, they uncover how small nudges, smarter tech, and better awareness can help us save water, energy, and money without compromising comfort.
