Men Sit Down on the Toilet Again and Then Pick Them Up
I f you use a urinal or stand up when you use the toilet, pee splashes dorsum on you.
If you share a bathroom with someone who stands when he pees, a fine layer of pee covers your bathroom flooring.
If you've used a urinal at the same time as someone standing next to you lot, his pee has splashed on you.
When men urinate standing upwardly, pee ricochets off the porcelain beyond the toilet or urinal. This may come as news to you lot, but interior designer Debbie Wiener is familiar with this "splashback" trouble.
"Information technology's a abiding problem betwixt men and women," she says, and one that comes up frequently when she works with clients to redo their bathrooms. Women desire a way to keep the toilet and bathroom floor complimentary of splashing urine, and then does Mrs. Wiener. "I tin can't walk into my bathroom barefoot!" she exclaims.
Debbie Wiener is a veteran of the interior design business, but she doesn't know of a splash-proof toilet to recommend to her clients. "If there was one, I would consider buying it," she says. "I've never seen such a thing in the trade magazines."
Instead she recommends the same solution she has settled on in her home: towels. She keeps a drawer total of large, bleachable towels, and every day she puts a fresh one on the floor in front of the toilet. She has no solution to continue pee from splashing on men'southward pants.
The flush toilet became a mass market product over 150 years ago. So why oasis't we designed ane that doesn't splash?
The Physics of Peeing
If you want to avoid splashing pee on your pants, you should stand up closer to the urinal.
This is the counterintuitive finding of 4 physicists at Brigham Young Academy's Splash Lab, which has published work on how schools of fish move in perfect coordination and the physics of skipping stones across a pond. In 2013, these four "wizz kids" used their understanding of fluid mechanics to written report splashback.
If you don't think splashback is a problem, or if you are a woman feeling mystified and alarmed by this article, wizz kid Tadd Truscott, a professor of Mechanical Engineering at BYU, has bad news for yous.
"In the absence of dividers between urinals, it would not be unlikely for urine droplets to travel a distance of 5 feet to the side of the urinator," Dr. Truscott tells united states in an email. "And if someone were standing side by side to him, they would virtually definitely get small droplets OF THE OTHER Homo'Southward URINE on their pants and shoes."
Truscott says he is working to mensurate exactly how much urine splashes when men pee standing upward. But he is certain that the problem exists with both urinals and toilets. "We practise know that a male of average pinnacle urinating into a traditional toilet while standing," he writes, "will launch modest droplets out of the toilet and onto the flooring, cupboards, and shower curtain."
"I take seen splatter marks well-nigh at eye level. No joke."
Truscott says the idea came to him and his beau researchers the same way it crops upward in every homo's life: when using a urinal while wearing khaki pants. Inspired by the inevitable stains on their pants, they congenital pee simulators out of sparse nozzles that sprayed h2o into buckets of water or against difficult surfaces.
They filmed each simulation with high speed cameras, and as they watched the splash in glorious, high-definition, wearisome motion, they reached several conclusions.
The first is that it'southward better to stand close to the urinal. As fluids stream through the air, they break into aerosol—the technical term for this is Plateau-Rayleigh instability—and droplets of urine splash more than than a stream of urine. This sounds counterintuitive, but you feel the soundness of this suggestion every time you sit on a toilet seat just inches from the water.

The BYU team also learned that a "depression bending of attack" produces the least splash. When pee hits the porcelain at a 90 degree angle, the splashback is terrible. But when the urine simulator aimed low—imagine hitting just above the drain of the urinal—the splash was more modest and not angled back at the urinator. This is likewise a good reason to aim sideways rather than directly at the urinal.
Their findings garnered more attention than the average fluid mechanics paper. The researchers presented their piece of work at conferences, the BBC profiled their research, and Seth Meyers joked about their work on Saturday Dark Live:
"Researchers at Brigham Immature University are studying ways to prevent urine splashback when men use the toilet. 'Hurry upwards!' said men in khakis."
For a brief menstruum, Truscott and the other researchers were the biggest thing in the world of toilets, advising men how all-time to pee to avoid splashback.
Just why did we demand their advice in the kickoff place? Why aren't toilets and urinals designed to preclude this?
An Old Problem
Our search for answers led united states of america to Duravit, i of the world'south largest suppliers of bath fixtures. We contacted their team of toilet designers, who are based in Germany. It felt like they inhabited a different universe.
"It is something we mitigated years ago," they told us over email, in response to a question near reducing the splash made by toilets and urinals. "To us, this is a story of the by."
As far as Duravit'due south toilet designers are concerned, splashback does not exist. It's a problem they stock-still long ago, and they test each toilet and urinal and allow "a maximum of three splashes of h2o 2 mm in size within a radius of 20 cm." Nothing to see here; move along. Now they're focused on making toilets that utilize less water or take a more hygienic glaze.
They merely gave one hint that splash might exist a concern: they make urinals with an optional "target wing." If men aim for the fly, which is a issues painted on the urinal at the best spot to aim for, information technology reduces splash past lxx%.
The toilet designers' merits—that they don't see splashback as a problem—was non a linguistic communication mistake. Their meaning was not lost in translation.
We side by side spoke to Tim Schroeder, president of Duravit'south U.Southward. sectionalization. He immediately told us, "Yous really simply don't get splash from modern toilets."
Schroeder did not audio like an executive denying a problem. He sounded baffled. "It'southward not a complaint that we've seen in the marketplace since xx years agone when we reduced the water area in toilets," he says of the splashing problem. Schroeder described how both Duravit and its competitors exceed plumbing lawmaking standards most splash. "This is an odd word for united states," he adds. "It'southward non that we're not interested, simply we don't hear this feedback."
"I've just non had this chat, and I've been with the company for 25 years."
With some pressing, Schroeder acknowledged that people might demand to search for that sweet spot—the all-time spot to aim at, similar the one indicated by Duravit's target fly. But he calls splash "human fault."
"Information technology's similar washing your hands in the sink. I could make a large mess, only I don't. I'thou conscientious."
Equally for the idea that splashback from toilets and urinals consistently stains men'due south pants, covers bathroom floors, and leads to countless arguments betwixt husbands and wives? That one of his products is then problematic that researchers like Dr. Truscott advise people to aim from the side or encompass the toilet water with a layer of toilet paper?
He simply could not believe information technology.
The Toilet Taboo
The splashback problem is not the just ongoing mystery in the world of bathroom design.
In 2012, Priceonomics reported on the struggle to introduce Japanese toilets in America. The toilets have features similar heated seats and a bidet office—the power to clean your derriere with water—and they are ubiquitous in Japan and nicer than whatever toilet you'll find in an American billionaire'due south firm. (If y'all're skeptical, ask yourself which you'd want if a turd landed on your arm: newspaper or h2o?)
The toilets get rave reviews from converts, but they remain largely unknown. In the aforementioned fashion that splashing toilets and urinals have persisted, Americans keep using an inferior engineering science: toilet paper.
According to Steve Scheer, president of a startup struggling to sell Japanese-style toilets in America, a major obstacle is Americans' reluctance to discuss bathroom bug. "Y'all wouldn't imagine how many people giggle nervously or say 'gross' when we endeavor to brainwash them about the advantages of the bidet seat," he says.

This same problem—that talking about toilets is taboo—plays the villain in a Freakonomics podcast that investigates a related mystery: Why don't nosotros play music in public restrooms?
As Freakonomics host Stephen Dubner relates, designers and architects advisedly consider sound when they pattern public spaces. It'south why lounges play slow music that influences people to linger and buy more drinks, why experts don't recommend open up function plans, and why elevator music developed as a manner to make standing in a tiny, moving room seem more natural. All the same in restrooms, we're left in silence to listen to each other's bowel movements. Some people are then mortified that they won't poop until someone flushes and masks the audio.
Harvey Molotch, an NYU professor and author of Toilet: Public Restrooms and the Politics of Sharing , tells Dubner that the toilet taboo disrupts the normal feedback loop betwixt customer criticism and better design.
"Where there'south a taboo and y'all tin can't speak freely nigh something, information technology becomes a identify where there's not accountability," Molotch says. "With the iPhone, we can question, 'How come up information technology's like this? Wouldn't information technology be better like this or that?' You lot tin't really [give feedback about] a toilet."
Based on his experience working on building committees, Molotch adds:
"Fifty-fifty working with the virtually prominent architects of the world, never is at that place discussion about the substance of the toilet stalls. And, as a result, you get the lowest person typically on the totem pole of the architectural firm is given that job. Then they sort of call upwards the mass supplier, and they just order the same stuff."
When we contacted Molotch about the splashback problem, he saw the same civilisation at work. "We have never been able, as a society, to put some real resources into the design of such things," he told us. "Again, it's the taboo which ways it would be difficult to bring upwardly [toilets] at executive meetings among those who run buildings."
In our conversation with Tim Schroeder, he and Duravit did non audio stifled by taboo. He described the "pre-testing and deep discussions about performance and maintenance" that take place when developing new products like a waterless urinal. He talked about working closely with customers like large hotel bondage and speaking with a customer whose toilet splashed due to an overly powerful flush—the only feedback, Schroeder says, he has ever received about splashing. The toilet design team mentioned focus groups.
It seems crazy that Duravit employees could spend 40-hour weeks talking about toilets without discussing splashback or soliciting complaints. Yet the power of the toilet taboo is equally crazy.
Even in our modernistic historic period of raunchy standup routines, our silence about bathroom habits results in incredible ignorance. In a legendary Reddit mail service, 1 man confessed that he realized he had misinterpreted comments almost men "putting the seat upwards." For his entire life, he had been sitting on the rim of the toilet when he pooped.
In the comments department, someone wrote, "My mom told me all the ladies in her office catch the poop with a TP covered hand and gently lower it into the water to guarantee at that place is no embarrassing plop noise."
We can't tell you if that'south true, and neither can anyone else, considering no 1 talks about bath habits. Go ask your friends if they pee in the shower and see what happens. Or inquire whether it'south "normal" to sit or stand while wiping, hover over public toilet seats, or meet a human being who always sits downward to pee.
When we broached the topic of splashback in the office, one Priceonomics writer exclaimed, "I thought it was just me!"
We're all the same baffled past Duravit'south reaction to our questions nearly splashback. Some men we've talked to say splash is not a problem. Maybe they have superior peeing form, or maybe they are even a majority. We suspect most of them take just not worn khakis in awhile.
Merely as far as nosotros can tell, the toilet taboo is keeping united states of america in an age of splashing urinals and toilets.
Would a Duravit executive hear about splashback for the kickoff time from a journalist if Duravit designers observed (with some precautions) people using toilets the same mode designers picket people use prototypes of their apps?
In a less restrained civilisation, wouldn't focus groups immediately bring upward splashback and how gross it is to clean urine of the rim of the toilet?
Non every toilet manufacturer claims that splashback is not a problem. In 2006, Kohler, which did not respond to our interview requests, unveiled its Steward urinal. Industry printing coverage noted that Kohler had "identified splash as the biggest problem with today's urinals," and the product declaration claimed that the urinal "virtually eliminates splash-dorsum."

In a sane world, Kohler would take shouted from the mountaintops that its urinal would end the splashback problem and liberate united states from urine stains. Instead Kohler touted how its waterless flush would relieve water, and information technology mentioned, well-nigh in passing, how the urinal "too" prevented splashback.
The only way to terminate this madness is to break the toilet taboo. If we desire to live in a globe free of flying urine and bring peace to bickering couples and roommates, we need to complain near toilets the aforementioned way nosotros vent about iPhones and Starbucks coffee cups. We need to tweet @duravit and @kohler to tell them nosotros badly desire a no-splash toilet. And we demand to acknowledge splashback and figure out how to forbid it.
Or men could all just sit downwardly.
