We theoretically predict and experimentally validate that when the impinging angle is below an invariant critical value of ∼30^◦^, the flow rate of splashback under human urination conditions can be significantly suppressed...

The only thing I've found that helps is if the urinal has one of these deodoriser mats. As long as you aim for the mat (coaster sized) there's no splashback, and a fresh scent to boot.

"Aim"? What's this "Aim" you speak of?

The only way I've ever known is to stand four feet back, whip down your pants and skivvies right down to your ankles and just firehose that sunuvabitch.

As God intended.

Over here urinals sometimes have a little image of a fly inside. This is where you aim for.

It all depends on the shape of the bowl.

Sitting is always better though.

I'm with you on this. But the good thing is, we're not alone.

Around 1 million liters (264,172 gallons) of urine are spilled onto the floor and walls of public restrooms each day in the U.S.

The best solution is to stand slightly to one side and pee almost parallel to the curved wall of the edge of the urinal. The goal is to get the stream to immediately adhere to the wall of the urinal and have friction slow it down as it curves toward the back, minimizing escape.

Taking this as an opportunity to share my hatred for American Standard urinals. Those pieces of shit are optimized to maximize splashback and their wall-to-floor ones were cooked up by the devil itself to make sure bathrooms have piss all over the floor when you use the urinal. I fucking hate American Standard urinals they're fucking awful. Shout-out the fancy waterless round ones though. I don't remember the name of that company but I love their urinals they work great and I rarely get any splashback at all from any height.

Here in EU/NL most stalls have installed an aim indicator where splashing would be reduced. Maybe you can find some imaging if you Google for it

A pub that I like shows football (n.am. soccer) matches. The urinals have little football nets with a little football hanging from a string mid-net, and if you aim just right, the ball spins around and around. I aim for that.

This advice is not easy to generalize outside of this particular pub, but I wish you luck.

Every once in a while I find a place with the old style chest to floor urinals, the ones with a bowl the size of a sink at the bottom.

It took me years to realize that these were designed so that a drunk could stand up and vomit like a gentleman.

This is what they took from us.

In elementary school we would count to three start the flow and then see who could back up the furthest while still getting it mostly into the urnal.

I like to aim for the little holes way at the top, where the water flows in from when you flush. I try to backflow my stream directly into the pipes. If you get it just right, you get this really deep, gurgling sound that emanates from the walls.

I found a spot to do it where it splashes into my eye.

It's a pistol, not a rifle. Get closer.

I haven't used a urinal since the '90s. Take the weight off your feet, avoid splash-back and fully drain your bladder to mitigate post-wee leakage by using a cubicle. And as a bonus, you'll never have to worry about shy bladder syndrome.

My technique is come in at a sharp angle, aim for the porcelain and not the water/drain/cake. 98.5% of the time this results in no discernible splashback, for me at least. If there is splashback, it's usually due to the design of the fixture itself and I quickly adjust to compensate - some are more shallow or rounded, others are awkwardly curved or angled, and the height at which it's mounted matters as well.

You might just be unlucky and have a super powerful stream or something. If that's the case, you're probably better off just sitting to pee.

Stop using urinals. Just wait for a stall to free up.

If you want the correct answer, don’t pee so hard. Control the flow so it’s soft and doesn’t splash.

I'd say aim at the back wall, but way down so it still hits the wall at an angle. And don't pull back your foreskin, pulling it back makes the stream harder and thus results in more splashback (I assume this isn't useful advice if you're circumcised). But TBH I don't like urinals, when possible I use a stall and sit down unless it's obviously dirty.

There will probably be a small logo, a mark, or, commonly, a depiction of a fly.

Pee on that.

Stand as close as you can to the urinal without touching it. I saw this advice on Reddit a decade ago. Someone said their drill instructor yelled at them for not knowing how to piss, and made them practice using a urinal. It works.

aim for the water or the colored mats... other than that it's all the same afaik. if the urinal doesn't have a mat, maybe carry one around in your pocket

I just came back from the bathroom and opened by browser to see this post. What are the odds??

I prefer to do it standing up but I guess you could do a handstand if you really wanted to

If someone is in the upstairs bathroom you’ll need to adjust for the highpotinuse

It's not just urinals. The first day of the year with shorts at home always brings a surprise chilly mist on my shins from a regular toilet. It is what it is. You're doing it as good as it gets. Either you're experiencing the normal amount of spray or your stream makes extra spray. Either way, it is what it is, it sounds. All you can do is lean forward and spread your feet asuch as you can to avoid collecting the mist. Side wall is my go-to. Lipped walls are my enemy.

Do you know what an arabic toilet is ?

Try a 22.5 degree downward impact about 45 degrees to the left or right. Pissing straight at the urinal always creates some backsplash.

You can do a 1080 into the urinal. I believe in you.
