New Urinal Designs To Help Prevent Backsplash

Did you know an estimated 264,000 gallons of urine are splashed out of urinals daily? That is not a pool I would want to swim in. Not even dip my toes. To help prevent return fire, these are a few new urinal designs created and tested by scientists with the intention of minimizing backsplash. Granted, these won’t help at all if you close your eyes and pee on the floor directly.

To resolve these problems, the team created a fluid physics model of how a stream of liquid splashes when it hits a surface like the back of a urinal, and experimentally tested these models by spraying liquid at surfaces at various angles.

The researchers’ Cornucopia and Nautilus designs both achieved a significant reduction in urine splashing, with the Cornucopia performing best. However, the Nautilus was considered the most ideal design due to its height, which would allow shorter people — including children or those in wheelchairs — to more easily use it. Its larger gape would also be easier to clean, and would be more accepting of poor aim, and therefore would also be appropriate for use on boats or airplanes.

Personally, I prefer the camaraderie of trough urinals. Did I ever tell you about the time I accidentally blinked one of my contacts out into a trough urinal filled with ice in a New Orleans bar? I 100% would have popped it back in if I’d found it (and become patient zero for swamp eye), but I could not. The rest of the night was a blur, both literally and figuratively.
