Get ready to say goodbye to splashback with these new urinal designs. A team of researchers from the University of Waterloo created a new urinal shape based on fluid dynamics—how liquids move and touch surfaces. The main feature is a curved, stretched-out basin that looks kind of like a long, shallow scoop or a slim trough.
Unlike traditional designs, which have a flat or gently curved back and a bigger bowl, these are crafted to control urine flow and reduce splashback. When pouring water on a flat dish, it splashes everywhere, but pouring it into a smooth, curved funnel makes it flow down neatly. This test urinal works the same, guiding urine along its surface tidily to prevent it from splashing back.

Most urinals use water to flush and clean after each use, but splashback can make them dirtier, needing extra water or cleaning supplies. This new urinal’s tidier design could cut down on flushing or intense cleaning, saving water and lowering maintenance costs. No one likes leaving a urinal with wet marks on their pants (oops!). The splash-free setup makes it more pleasant and less embarrassing, a small but awesome perk for users.
Also, the team studied how animals like dogs pee with barely any splash by aiming at specific angles or surfaces. They used computer simulations and prototype models to mimic these natural ideas, crafting the urinal to work perfectly for humans.
