Can you solve the problem of male urine splash out of an ordinary toilet?

Why did you italicize the word liquid?
Anyways, you can try peeing while sitting down.

If your worried about it do what the girls do, sit down and pee.

There is a way and it would look a lot like how you put oil into your car, but inversed.

I’m old so I sit down to pee when I can because when I relax because I can’t really be sure pee is the only thing that will come out.

And it is funny. I live with my sisters 21 year old son and his GF. I have a deal with the GF. Sundays I give the bathroom a deep clean and she is responsible for the rest of the apartment (excluding my dishes and my room).

We have the bathroom equivalent of the swear jar. 25 cents if you leave the seat up. His resistance to feminize him pays for our toilet paper.

@johnpowell

Sounds like a smart deal all the way around :)

@ibstubro

This won’t eliminate the splash but it will make it much easier on the cleanup.

They sell bathroom rug sets and in addition to the main square or oval larger sized one for use when stepping out of the tub or shower, some of them have a smaller one with a U shaped indentation cut out.

This is designed to hug the base of the toilet. If you keep it snugged right up to the toilet the way it’s designed, that’s where the splash ends up.

Then once a week or so just pick it up and chuck it in the washing machine. However, if you don’t want it to wear out prematurely, don’t put it into the dryer. It usually has a rubber backing and the heat from the dryer will wreak havoc on that.

Besides, these sets are usually made from synthetic fibers, so they’re pretty fast drying just by draping them over a line or something.

Granted, it’s not a perfect solution, but at least it spares you having to clean the floor area all the time. Just pick it up and toss in the washer.

BTW: A lot of these sets come in softer pastel colors like pink, blue or white and are perceived by some as being more “girlie” or pretty looking.

However, they also come in darker shades like maroon or black (even tho the lighter shades are more commonly seen) so you just have to persevere in your search if you prefer to avoid the pretty look.

@Buttonstc still spreads the germs round until laundry day, right?

Unless someone has a currently active UTI infection there really aren’t germs being spread around.

Urine is generally considered sterile and a whole lot safer than feces which carry a whole raft of nasties including E-Coli

As I said, it’s not a perfect solution but it does make cleanup easier for those guys who don’t like the idea of sitting down to pee.

IMO, sitting down IS the perfect solution. Definitely no splashing on the floor that way.
But then, not all guys are as sensible as @johnpowell, are they :)

And if someone is excessively worried about germs, just buy two sets and put one in the wash at the end of each day.

These sets are certainly cheap enough to do so.

However, personally speaking, if I had to live with a “splashy” guy, I’d be far more concerned about not having to scrub the gunk off the floor than I would be about whatever “germs” were in urine.

Everybody has their own priorities.

PS: Before a misunderstanding occurs, let me clarify my statement about urine being sterile. Technically that’s not the most accurate way to describe urine being benign compared to feces. Sterile would imply absolutely no living organisms.

So, for the sake of accuracy, let’s put it this way. Absent an active UTI, urine is non-toxic to humans as there is not a sufficient concentration of organisms that would be harmful to humans.

Obviously the same cannot be said for feces which contains high concentrations of multiple potentially harmful organisms, E-Coli being but one example.

This is the primary reason for why we should wash our hands thoroughly after using the bathroom. Urine is not the problem.

Soon after my surgery, my stream came out in a shotgun pattern. I kept a Red Solo cup on the top of the toilet tank and went in there rather than in the toilet. I’d then empty it in the sink, rinse out the cup and wash.
The bathroom remained sparkling, I used a lot less water than a toilet flush and got back my ability to pee standing up.

Why is peeing standing up so important to a guy? It makes a mess.

While fresh pee is not as harmful as feces, ‘fresh out the gate’, it does attract microbes and goes through a type of fermentation process that turns it into ammonia. In other words, in a heated bathroom in 3 days, the urine-drips on the floor become not just riddled with bacteria, but they give off a gas and stinks and is caustic. Boys and men: if you sprinkle when you tinkle, wipe it the hell up. If you don’t want to belittle yourself to wiping up your own wee, sit down. grrrr.

@cazzie This is just my own, subjective, observation. I do not have ultrasound data to back it up
I empty out better when I’m standing. When sit I always feel there is more left.

I solve the problem by peeing while I am in the shower. I shampoo, pee, wash, brush my teeth and shave in there. Sometimes I’m doing all at the same time. When I step out and dry off I am all sparkly clean.

The problem is the shape of the toilet bowl. It reflects urine back out and up.

We need a new toilet bowl shape; somewhat trapezoidal that leans outward at the bottom, instead of inward. In that way, the urine will reflect in the water.

I understand why toilets evolved to what they are today, but rankly, their design wasn’t particularly good.

Sitting down doesn’t work if the toilet is small.

Toilets in the US come in two major sizes – the ‘regular’ which is almost circular, and the ‘elongated’ which adds several inches and gives more room for the bowl to accept urine.

See this: link

For tall men (such as myself)— a tall person has difficulty peeing sitting down because the toilet bowl and seat are simply too small. An elongate seat is big enough.

So for those who advocate that men should sit down when peeing – a prerequisite for that must be the right size toilet.

I don’t think of a few drops on the floor as being necessarily stinky, @cazzie. Not that it’s good and not that it’s not “cleanup worthy” but I don’t think it’s going to make the bathroom noticeably smelly.

@elbanditoroso: I’m willing to bet that’s why most toilets in public places are the elongated ones. Less mess on the floor from all genders.

@jca – I agree, most in public place are, at least in my experience, at least in mens rooms. Not sure about ladies rooms.

This is a recurring topic – every couple of years we get into a discussion about how men should set because women don’t like the mess. And the suggested solution is that men should sit. Surprise.

My guess is that evolution and natural selection actually promoted male standing while peeing, because the male was out in the forest on the hunt (or marauding other tribes to save his own tribe) and sitting would put ancient man in a more vulnerable position for the duration of the urination. Standing while peeing was a better and more strategic way to pee for a warrior.

Women, who were in general back at the tent or the cave, could sit because they were in a more protected place.

@elbanditoroso: Ladies’ rooms, too. Not all ladies leave a neat seat. It’s always amazing to me that people can walk away from a toilet seat and leave pee on it, (or blood or hair) and not think to wipe it for the next person.

Surgically rerouting the ureter into the anal cavity.
At birth, preferrably.

@ragingloli – that would go right along with moving the cranium into the anal cavity, for people who have their head up their ass….

Why do men stand when they pee?
Because they can.

I don’t want to be in the habit of sitting, and then have to learn all that ‘hover’ nonsense for public toilets.

^^Plus, it’s quicker. Sitting down is too time consuming and I’m always prompted to put toilet paper on the seat.

Asking a guy to sit is like asking him to pry the top off the mustard and go back to to dipping it out with knife.

High speed photography shows it is not always the guys’ fault. Physics is at play. Drop water from a height and drops will rebound.

Maybe a thin film that increases surface tension might help. Or a drop of liquid dish soap that increases bubble production while keeping the bowl clean. I see a study in the making.

Sometimes I get fed up with having to clean the outside of the toilet more than the inside of it.

At those times I’ll say, “Real men sit!” He doesn’t seem to get the message, I’m not sure why.

@snowberry Ask him to “Get that thing reamed out so it makes a nice stream.”

But before you do, please try the experiment above. Do it without telling him so the results are a fair blind study. Try just half a drop of detergent.

Actually I’d like to see all members of the stand-to-pee set try it and report the results here.

Put a piece of toilet paper on the water surface and run the experiment again.

I remember a good friend of mine, a long time ago telling me she did her future daughters-in-law a favor by teaching her sons to aim properly when they peed. LOL She was an obsessively clean registered nurse turned housewife so I don’t doubt it.

I think any household with men and boys should SERIOUSLY consider the addition of a urinal with any bathroom upgrade. In fact, I told my daughter in law last week after a tirade about the grandsons and their crowd of “inaccurate” little friends to install a urinal in the garage and problem solved.

Float 2 sheets of toilet paper in the water before letting loose and you will notice an appreciable lessening of errant pee splashing.

@Cruiser… didn’t I just say that? lol

Sit, shake. Oh wait….

The solution is obvious. Be a woman and live alone. Sooo much easier.

@cazzie You said “a sheet” and any guy knows one single sheet does not stand a chance against a super sized fast food drink! ;)

I said a piece.

The engineer in me just cant leave this alone.
We need to be able to run a controlled experiment my matching mass flow rate and velocity.
The mass low rate is easy to measure – simply pee in a cup for a short fixed time, say 10 seconds, and measure.
But how do we get velocity…. hmmm…. how can we do that without equipment?. GOT IT!!!
Use Dynamics!
Stand on the edge of the patio and pee as close to horizontally as possible Measure the horizontal distance from the exit to where the pee lands. Measure the vertical distance from the outlet to the ground. Using basic dynamics equation: s=½ at^2 where s is the height. and a is gravity, we can solve for t. Then use V= d/t where distance is the horizontal distance of the pee. That will tell us the pee’s exit Velocity. We can then use that to determine the height of a storage can connected to a hose that will deliver liquid at the same velocity and flow rate as the real thing. With such a setup we can readily try different solutions.
Easy Peezy!

@LuckyGuy – Urine a class by yourself….

@elbanditoroso Thanks! I think I’ll do the testing on the pee gravel.

Shhh… Don’t tell anyone… I just made an Excel spreadsheet that calculates the velocity. Enter the vertical drop (or your inseam plus a bit) and the distance you can reach and it will tell you the muzzle velocity.
I am so ashamed.

(6.14 fps, 1.87m/s)

frames per second?

@ragingloli Feet per second?

@ragingloli I agree with you! It drives me crazy but that is the way the term is used here so when in Rome….

Hey, just piss off the porch. Or into the garden.

My Ex sometimes stood up and sometimes sat and I always wondered what made him decide to do which when.

Seems to me that a walk-in shower could be a walk-in urinal easily enough. A small urinal shaped fixture connected to the drain, opposite the shower head. As you exit, the flush activates the shower for a bit, flushing the urine and rinsing the surrounding tile.

Might want a grid floor so it holds less water in the event of multiple urinal users. Or maybe the shower head could be designed to ‘hit the hole’. A floor grate along the wall/floor that allows the shower water to enter the drain without running across the floor?

If you can guide the stream to hit the porcelain above the water line so that it goes around the curve at the back before entering the water, perhaps the water on water splashing can be avoided. Now if you are running an open choke and your muzzle pattern is too open, you gotta be closer to the target to do this. I am unsure if barrel length or bore have any impact on stream pattern, but as @LuckyGuy mentioned, damage to the end of the barrel can negatively impact the stream pattern

@majorrich You suggesting an adjustable choke? Maybe modified or full?

I had a thought that manipulation of the end of the barrel, not unlike the end of a garden hose one may be able to influence the spray pattern and volume of flow.

Laughs, we are spending too much time on pee.

None of you guys know to hit the side of the bowl with your stream? I simply refuse to believe that simple technique is not common knowledge.

A friend of mine’s mother cross stitched a piece he keeps above his commode. “If your hose is to short of your pump is too weak, stand close to the pot or you’ll piss on your feet.
@ARE_you_kidding_me That was my go-to technique, at night I sit.

Frankly, I am surprised no one else wanted to know their personal muzzle velocity.
Just PM me with the two numbers and I’ll give you the answer. Free of charge.
Where else are you going to find a deal like that?

@snowberry “...please try the experiment above. Do it without telling him so the results are a fair blind study. Try just half a drop of detergent.”
Actually I’d like to see all members of the stand-to-pee set try it and report the results here.”

Exactly how would I do that so he wouldn’t know? LOL I can’t exactly track his toilet usage!

@LuckyGuy I lack the equipment to do the experiment myself, but having said that, your experiment doesn’t take into account for lack of accuracy.

I was a janitor for my first year of college to pay the bills. I cleaned 40 toilets and ten urinals a night. Urinals are way worse to clean. I’m not sure how it exactly happens but there is a lot of wall splatter that happens. The physics don’t add up but it happens and I had to notice it and wipe down the wall behind the urinal.

And I have seen shit sprayed on all three walls of toilet in a womans restroom. I assume it was hovering gone horribly wrong.

@cazzie I am trying to address the water droplet rebound effect. I cannot control the inaccuracy…. WAIT!!! YES I CAN!!!

Have you ever peed on an electric fence? I haven’t either, but I have heard stories.
Let’s electrify the seat and bowl when an optical sensor detects a person standing in front of the bowl AND a small radar unit in the tank detects a doppler signature between 0.5 m/s and 5 m/s . If both conditions are satisfied the toilet rim is armed. As a courtesy an indicator light would be illuminated when armed (only half the time.) Men would suddenly be very careful about their aim.

@LuckyGuy – you could build in some self triggering Tasers on top of toilet tank… the technology all exists, it just needs to be implemented.

Don’t tase me, bro! Don’t tase me!

@elbanditoroso the taser does not fit the punishment to the crime. I like the idea of using the conductivity of pee for enforcement.
I have some experience with it . Back when automotive high energy ignition was still experimental I was setting the ignition timing on a test car using an old timing light without an inductive pickup. As usual on old convention ignitions I had to remove the spark plug wire and install a spring extension so the test lead would attach to the plug. I reached in and chalked timing mark so I could see where to align the distributor.
I started the car, leaned way over the fender and pulled the trigger on the metal clad timing light. That sent the ignition pulses up into my hand through my body and out the sweaty spot that was leaning against the fender. Pow! Pow! Pow! Pow! before I could get up off the fender. I never forgot it.

Myth Busters did a segment regarding urinating on an electric fence I was astonished at the result!

I tried the sheets of toilet paper on the water surface? They folded in ½ and sank.

Maybe the detergent tomorrow.

Mythbusters electric fence bit.

@ibstubro Wonderful! Data! We all know without data all we have are opinions.

If you give me the two numbers I mentioned above, distance and inseam, and I’ll tell you your muzzle velocity. That might be a factor.

Don’t get arrested while doing the distance test.

All this banter because what??? 90% of men refuse to sit and pee?
maybe if their wife made them clean the bathroom they would either aim, just above the water line in the bowl, or freakin sit and piss.

My hubby DOES clean the toilet at least half the time, and he still stands. But theres a permanent stain at the base of the toilet that can’t be removed (probably because we don’t clean it more often). Nevertheless, I can’t say it more clearly.

Real men SIT!

@snowberry: I think the grout gets stained and then no matter what, it can’t be scrubbed out because it’s porous.

@snowberry – “real men sit” sounds more like wishful thinking than anything else.

What’s your evidence to support that assertion?

The SO kneels down on one knee in front of the toilet when he urinates at home. I have yet to see any sign of his use afterwards, other than the the toilet seat is left up.

@Pied_Pfeffer – that gives new meaning to the phrase “praying to the porcelain god”

@elbanditoroso Hmm, when I met him, there was a statue of Buddha on top of the toilet tank, but I’m pretty sure that it is just a glazed ceramic.

Here’s are two other reasons against sitting.
!) If mine ever touched toilet bowl rim I’d have to cut it off! Ick! Ick!! ICK!!!
And
2) That water is cold!

@LuckyGuy Reminds me of that old joke. Two guys are pissing off a bridge. The first says that water is cold. The other says yes, and deep too.

@luckyguy. There is some kind of regulation where I live that the toilet water can’t be that high. Must not have that regulation where you live. :-)

@chyna If your parts dangle in the water I’m going to wonder. I’ve found the water before. Thankfully it was the cleaning solution, but it’s still gross.

@chyna If you recall from another thread I am the guy who washes his hands before AND after a bathroom event. I try to keep my equipment pristine.
If it ever touched I wouldn’t be able to go for a week!

I’ll have to suggest low flush toilets to the building superintendents.

@Adirondackwannabe I dont get it!

I’m going to have to take pictures of the toilets around here and their water level. You guys are telling fish stories.

@cazzie And 6 inches is this long.

I can assure you the calculation and excel spreadsheet is no fish story. The numbers I posted were real. How many guys on the planet know their pee exit velocity?

I can’t wait until the first time someone sees @cazzie in the mens’ room taking pictures of toilets, and asks what’s going on.

“This is for a research project” ...

@cazzie Nope, no fish story. A warm day and the parts dangle down a bit. Until they touched the water. Blech.

Finally, @LuckyGuy a morning alone for a patio pee.

Inseam: 32”
Distance: 37”

I have to wonder why you would dangle your parts in the toilet on a warm summer day so long that they found water? Is that a mountain thing?

@ibstubro 37” Impressive! Remember you must be firing horizontally, not lobbing it as far as it will go. Also actual measurement of the “outlet height will be more accurate. For now I will assume 34” from your inseam number.
Answer: 7.09 fps 2.16 m/s

I stood on the edge of my patio and spray painted marking lines on the “pee gravel” every 6 inches to get the distance measurement. Height was obtained by using a measuring tape.

I’d be happy to recalculate if you provide higher resolution data.

I figure more men have walked on the moon than those who know, or care to know, their PMV, (pee muzzle velocity).

Damn, I thought this was a pissing contest, @LuckyGuy. I’ll admit that I arched up, but I didn’t use any other means of artificial enhancement. I also waited for the morning pee.

@ibstubro I can add a factor for elevation or declination, but how would you measure accurately? That would require a partner standing alongside with a protractor. It is far better to just go with horizontal. We all can do that – even in cold weather. ;-)

Check it tomorrow. I’m not going anywhere.

@Luckyguy
Had a great opportunity to get a good measurement for my entry for our data. Spent a long time at the waiting room for a blood draw and then the race home to get my eyes uncrossed. so the chamber may have been overpressured a bit.
30.5 muzzle height
40.25 distance maximum, reducing to 31 as the reservoir became less overpressurized
58 second duration of event. LOL (Had to go very very badly)

I am now going to go measure the distance from the rim of the seat to the water in my European toilet. You would have to dangle 24cm to reach the water in my toilet.

@cazzie I just checked my seat rim to water height. 14.5cm! It is a 3 gallon per flush toilet.

@majorrich Holy…! Do you have to hold on the wall to keep from being knocked over?
Was that 40.25 when your elevation was zero, meaning Horizontal? That is how I wrote the program. You can’t lob it up and arc. The stream has to come out horizontally for my ballistic equations to work accurately.
Assuming is was horizontal your numbers are:
7.49 fps, 2.28 m/s

I bow to your prowess! Please resend the data if you were firing with elevation.
—————————————
Ladies: I’ll bet you didn’t know this process could be so complicated. Thrust, elevation angle, position, continuously varying pressure, and there is this. So many things to consider… and it has to be done in so short a time.

Freud would be so disappointed. I have no envy at all.

I think you all are doing god’s work in this discussion.

It makes you Bladder Day Saints.

The interior contour of the toilet surely has a lot to do with it also. I can bet that my toilet has a very different interior profile than the ones you guys are talking about where your willy hits the water.

[Mod says] Moved to Social on request. Carry on.

We need to write to Mythbusters and get them to do this.

I took some pains to be horizontal. Which is pretty easy given a short barrel. I make up for it with high velocity rounds I guess. It only hit maximum distance for a short time when the bladder was in full spasm overdrive. It did waver between maximum and somewhat less than that before the magazine was empty.

90 responses to male urine splashing.

@chyna Laughs, tells us where our brains are. I just walked into the men’s room and shoved a ruler in the bowl. 51/2 inches if anyone cares. :)

It’s turning into an engineering exercise. Always an interesting topic.

@Adirondackwannabe That’s the same distance I got. 14.5 cm, 5½ inches. Yoursmust be the 3 gallon per flush unit too. Vintage 1986? That is when I upgraded from the 5 gallon per flush.unit, vintage 1957, which was even closer to the rim!

To be clear it is not the spray nozzle that dangles perilously close to the water. (I wish). It is the now useless package that unflinchingly stares danger in the face.

Guys,
It’s the weekend. Time to start measuring your “capability”. Silly as it sounds, consider it a baseline, or a data point to compare with at a later date. If you are over 50 you should already have your PSA numbers. You can now add your UEV , urine exit velocity, into your medical records. Down the road, a reduced UEV might be an early indicator of BPH or a urethral stricture, or prostate cancer. Who knows? This might become a diagnostic standard. (Of course the “approved” test would involve microwave and acoustic Doppler readings to obtain velocity so the doctor can charge $300 for the office visit.)
If you want to get higher resolution readings you can stand on a picnic table or pee off a low balcony. The ballistic equations I used ignore wind resistance as it is minimal at these speeds. To keep the speeds down, and for safety, do not stand on anything higher than 12 ft. That keeps the maximum velocity well below 30% of terminal velocity.
Now, let it fly. And don’t get arrested for indecent exposure. In some states that is considered a sex offense and puts you on a SO list.

Have our rated velocity engraved on the side of the barrel. The Caliber may have some impact on the velocity. Hank Hill may have a higher muzzle velocity than say, John Holmes (if John were able to achieve a true horizontal flow.

The ballistic equations are based upon the flight path once it leaves the barrel. Barrel length, caliber, or twist ratios are irrelevant once the projectile has cleared the nozzle. The velocity is what it is.
The Wadd could make more precise elevation measurements since he can use both sides of the protractor.

^^^ LOLZ the wadd might get a better laminar flow but as you say once it leaves the nozzle it goes where it goes.
I re-created yesterdays experiment with very similar results within .75 inches so I guess I am a high velocity kinda guy.

@majorrich If you pee in a cup and time it for me we can calculate thrust and impulse. With some clever plumbing you can use that thing as a thruster for the ISS.

Accurate measure is very difficult (of the stream, not of what my sister once described as _my handy dispenser).

I placed my feet on a line in the concrete, cut loose, and measured the distance from the line.

Wrong.
Instinctively I had thrust my pelvis forward in an effort to avoid splash-back onto my feet. I estimate I overstated by maybe 8 inches?
I’m not sure I’m capable of both the vertical alignment and the horizontal stream simultaneously without undue effort?

In my second trial, I was just sending the stream downrange and leaned over to check my elevation setting.
I was reading an interesting article about space propulsion and of ion drives. The scientist said the ion drive he was working on made about the equivalent thrust of mouse flatus. I found that pretty funny. I got to thinking when the astronauts inside the space station urinate, would they not also generate some small vectored thrust that would have to be occasionally need to be corrected for? In a friction free environment, a tiny push well really because of mass a whole mess of tiny pushes might eventually effect the orbit. So mouse flatus over time could mean close to light speed travel? (Wow I went far afield of straight urine talk well, I’ve had a couple adult malt beverages)

@ibstubro While dry firing, so to speak, you could practice standing back from the line and thrusting your pelvis forward so it just reaches the line. Later you can use that same stance to fire with ammunition. Ideally the elevation angle should be zero, horizontal, but realistically plus or minus 5 – 10 degrees is trivial. You get a big error if you start aiming high and lobbing it.
