Overview

• The 'Cornucopia' and 'Nautilus' urinals, developed by researchers at the University of Waterloo, use fluid dynamics to minimize splashback to just 1.4% of conventional urinals.
• The designs leverage a critical 30° angle for urine impact, drastically reducing splatter and improving sanitation in public restrooms.
• The Nautilus model is specifically designed for accessibility, accommodating users of varying heights, including those with disabilities and children.
• Researchers estimate that replacing all U.S. public urinals with these new designs could prevent 1 million liters of urine splash daily and save up to 10 million liters of cleaning water.
• Inspired by natural phenomena like canine urination angles and nautilus shell geometry, the designs represent a breakthrough in sustainable and inclusive restroom innovation.
