Quit ya bitching and roll the math.
Some stand to pee. Some sit to pee. everyone sits to shit. In a mixed gender household the seat gets most use down.
The meme is making it look like seat down is presumptuous, which it is not. It has the least effort vs hygiene trade-off, since sitting to pee is much more hygienic.
Real pros streamline and take off the seat and lid altogether.

Especially common for public bathrooms in Asia and parts of Europe, specifically because there is no direct skin contact which reduces risk of infection. There are also claims that you poop easier squatting than sitting.
If you don’t shut the lid before you flush it sends poopoo peee particles flying around the bathroom onto your toothbrush
Mythbusters found it makes virtually no difference, and lid down can actually make particles go further due to the pressure forcing them through a smaller gap.
Myth Busters are not a solid scientific source. I discussed the issue a bit, linking to some papers in another comment here: https://feddit.de/comment/5298414
Although Mythbusters is not a peer reviewed scientific source, they do employ reasonable standards of experimentation.
And the first source you posted is particularly interesting, with similar conclusions to what I remember from Mythbusters; that lids reduce the total number of particles found, but that the particles produced from lid use last longer and are larger. So a lid closed situation can;t really be said to be more hygienic.
Unfortunately on a cursory skimming of the other articles none of them seem compare toilets with lid down to lid up, they all seem to look at lidless toilets only. Thus, they can;t really speak to the topic of lid use being more hygienic without the direct comparison.
What episode was this? I can only find evidence of the opposite of what you’re claiming here
The plumbing authority link? Yeah, they leave out the part where the Mythbusters found poop everywhere when flushing with the lid closed as well.
I always flush with the lid down. Keeps less in the air.
Hate to break it to you, toilets aren’t airtight. The particles go right out the side and tend to last longer in the air when the lid is down. It’s creates a reduction in visible particles as it seems the lid causes bigger particles to form so ergo less “visible particles” but they are just bigger and last longer for some reason versus the smaller ones. As has been demonstrated by the Mythbusters and many other studies, the biggest factor is having proper ventilation otherwise your gonna find shit particles everywhere regardless of if you close the lid or not.
The reduced airspeed of the shit particles thanks to the closed lid slows the buildup of shit particles on bathroom surfaces enough for my regular cleaning to be sufficient
The closed lid increases air speed, not decreases it as you create a higher build up of pressure 🤦♂️
Honestly don’t worry, as Mythbusters pointed out that neither are a health concern due to the low concentration relatively speaking and if anything it helps your immune system build up defenses against E coli and the like. Just know lid up during your flush means the sent lingers less. Then after the flush I would advise closing the lid to keep any lingering sent in the air of the toilet bowl and less likely to be disturbed by any airflow in the room. Just don’t like seeing misleading info spread around as honestly the science behind it is pretty interesting.
But that applies to most commercial toilets with high flow rate. Most home toilets don’t do much more than let gravity do the work. There’s no aerosolized particles, just a few splashes or droplets that may escape
Home toilets use the bowl filling up to create a siphon through the drain trap. For that to work your toilet must first raise the water level above the top of the trap to create the pressure with its weight to start the siphon. I.e with the lid closed you are forcing more air to compress in a smaller volume generating a pressure difference outside the bowl and internally. Leave the lid open and that volume of air goes directly into the room without much resistance creating less pressure in the bowl compared to the surrounding air in the room. Hence with the lid open the distance, the spray travels is lower as it has a lower velocity.
For reducing visible particles, not the nano particles which have a higher concentration. Regardless it’s all kinda moot as neither produce levels of bacteria that could realistically get you sick unless you stick your face above the bowl or to the side openings by the lid while flushing and that person has an infecfion. Just wanted to clarify the science behind it.
Why don’t these things have more of a seal by now? It’s supposed to be the future.
That’s not making sense to me. Would you be willing to find your sources? Larger particles would not spend more time in the air as far as I know. It’s almost like you’re claiming it’s better to sneeze wild straight out everywhere instead of into your elbow, handkerchief, or tissue.
Best reason to close the lid: The things you do in the toilet smell. Lid keeps the smells from spreading.
Actually it doesn’t, flushing with the lid closed can leave the particles in the air for up to around 11minutes longer as they exit the side of the toilet with more velocity and pressure. It’s not a sealed system.
Yeah, I’m aware that toilet lids are not an airtight system, I’ve seen them. It still does slow down airflow enough for most of the poop to settle instead of spreading to your whole house.
No it actually does not, it increases the spread and creates a pressure build up compared to being open, you are initially adding volume into the toilet when you flush with the lid closed this pressure build up is greater and spreada the particles further. You are essentially creating a shit nozzle on the sides of your toilet. All the lid does is help the particles become bigger so there are fewer visible particles but they are bigger and travel further, while remaining airborne longer due to their velocity.
Tell me you haven’t owned a house without telling me you haven’t owned a house
I own two houses and seven toilets and I can’t say that I have ever had my toilets stink unless they are broken or not cleaned regularly.
Also, they might be stinky if I was to get my nose all up in there, but I tend not to do that.
As far as I know, my bathrooms all have working fans as well. That could cause issues if they were broken.
