Flushing the toilet after every wee.

10 litres per flush is a huge amount of water per wee (that's what I believe our cistern holds).
I don't think it's necessary to flush after every wee. My friend thinks I'm tight and unhygienic.
What's your view...
Are you a 'if it's yellow let it mellow'...I am reasonable
Or...'eww you filthy sod'..I am unreasonable

I don't under how people are being woken up by a toilet flushing when there are other noises in the night but those don't wake you up? Don't others wake up just by someone getting up go to the loo? The door closing? Floorboards creaking? My loos really don't make that much noise. 🙄

If it’s just me here then no I often don’t flush, though sometimes do out of habit. If there is any chance of anyone else using the loo then it’s flushed every time

That is absolutely rank. Your house must smell of piss. Can always smell when the kids haven't flushed.

Nope

Unflushed loos stink! Flush every time! Who wants to go to a loo that stinks of urine? Who wants to pee on top of someone else’s pee? Grim! 🤢

Can I play the 'foreigner' card and ask what the deal is with sharing bath water? So, you have a bath and when you're finished you leave that lukewarm water full of soap suds and skin cells and the dirt you scrubbed off yourself, so the next person hops into THAT water and uses it to clean themselves? I don't want to google it 😬

Not playing all superior, we do wacky stuff where I'm from too.

With regards to the flushing question, yeah sometimes I pretend to 'forget' to flush so we can save some water, but that's mainly because I work from home a lot and have a bladder the size of a subatomic particle.

No. My partner and I both shower in the morning and dont have physical jobs so are generally always pretty clean. He is literally a dip in and out of bath in under 5 mins. No scum and still really hot ....so rather wasteful actually if he has a bath to himself

It's often my own pee as im here alone 60% of the time

We don’t flush a wee at night.
In your situation, if I was home alone for most of the day, then no I wouldn’t flush a wee.

isitmytime · 09/02/2026 07:34

I don’t flush the ensuite toilet during the night because it backs onto my neighbours bedroom and their bed is against the wall. But any other time I flush. I have a sense of smell to rival a bloodhound and I can honestly say I’ve never smelled stale wee from doing this.

I don't know why you're bothering to ask!
'You do you' is what matters here.

In terms of saving the planet and your own water bill /usage, do what works for you - and that is saving water.

As for the posters who say it smells- well, leave the lid down or even open that thing called a window !

There are far more important things in life to worry about.

Christ people....if we've visitors of course we flush each time but ordinarily it's just me here 4 days a week as partner works away and only home x 3 days a week.

Is now the time to confess to sharing bath water too lol

Edited

I'm more than happy to admit I'm minging and my personal hygiene is far far from perfect. But urghhh this turned my stomach. We're not in the 80s any more. This is why showers were became popular.

Pasta4Dinner · 09/02/2026 08:57

im alone at home during the day and I wee constantly because I drink so much. If it doesn’t bother me I don’t see the problem.
If someone else is here then obviously I do something different.

MIL was obsessed with toilet flushing. She would blow her nose and put in the toilet and flush rather than throw the tissue out. Her bathroom stank of pee, probably because of FIL.

Pour the whole bottle down. We have horrendous limescale here! Only thing which sorts it out if we have left it too long.

I would if I could, but they get all defensive and wont let us sort it. FILs pee is thick dark.... its just grim. I dread going to the loo

Squirrelchops1 · 08/02/2026 20:33

I think so
..short or long flush
We only have 1 button though.

So add a hippo to your cistern so it uses less water, or change it for a modern one with two options! Unless, of course, you’re going to manually scrub the deposits from the pee off the porcelain just below the water regularly!

zingally · 09/02/2026 09:57

We used to be "if it's yellow let it mellow" folk, but fairly quickly, it made our toilet seem stained and dirty MUCH quicker than if we just flushed each time.

We now flush during the day, and overnight leave it until morning.

The deposits aren't from pee. It's limescale.
If you scrub too hard the glaze comes off and you're left with the unglazed bowl round the water line.

Belladog1 · 09/02/2026 10:09

My toilets have 2 buttons side by side, a large and smaller one. But maybe I have gigantic fingers, but I end up pressing them both together.

Weirdly, I had this conversation with my partner last night. I have always insisted he flushes the loo if he gets up to wee in the night, but he said yesterday that he hates doing it as he doesn't want to wake me. I told him he woke me anyway getting up, so it doesn't matter. I live alone 75% of the time, and I still flush after every wee.

InveterateWineDrinker · 09/02/2026 10:38

We have family in Portugal and a home there, and although there have now been two very wet winters in succession there has been a decades-long water shortage all across the Alentejo and Algarve regions. Profligacy with water is one of the most antisocial things you can do: it is almost unthinkable to flush after just a wee in the home. My uncle goes out to piss in the garden.

The UK is rapidly heading towards structural water shortages too. If you're really using 10 litres per flush then honestly that's pretty wasteful. Our toilets use 3 litres on the short flush and 4.5 on the long one.

FruitFlyPie · 09/02/2026 10:46

I'm honestly shocked by this thread. Every other thread on here about domestic habits, I'm always on the "grim" side. I only change my sheets every few weeks, clothes get a few wears, I rarely use bleach, use cold water for laundry, etc. But I've never considered not flushing the toilet at any time, and if my kids forget, it absolutely stinks.

XenoBitch · 09/02/2026 10:50

ThrowingDi · 09/02/2026 00:45

Wee isn’t water though. Haven’t you ever been to a public restroom? They fucking stink due to all the residual body fluids. That’s what your home stinks like

Edited

Bullshit.
They also stink because 100s of people use them every day. That is not the case with a loo at home.

Ferrfoxache · 09/02/2026 11:16

Being a woman of a certain age i get up at least twice during the night to pee. There was a time when i'd "let it mellow" because i didn't want to wake my husband up with the sound of the toilet flushing until he commented that he'd rather be woken up by the sound of the toilet flushing during the night than be hit by the smell of stale piss ( his words) when he gets up in the morning 😬So for that reason we flush every time. There are many other ways to save water where it doesn't have to become a hygeine issue.

If it stinks they're not drinking enough, which is obviously common in children. When you drink a lot of water wee is usually very dilute and doesn't smell. I've experienced using a toilet where the previous person has clearly been dehydrated even to a small extent and it isn't pleasant. When you drink a lot it really isn't an issue to avoid flushing for a wee or two.

JoffreyArcher · 09/02/2026 11:39

I've never seen so much Pearl clutching.

If you or someone using the loo has stinky pee, then flush. But also maybe drink more water so your pee isn't so concentrated.
If you are sharing the loo with lots of family members, then flush, because other people's pee is more unpleasant than one's own.
If you have visitors or are a guest, flush every time. If pee goes on the floor, wipe it up.
If you aren't sharing, and don't have stinky pee, if you are concerned about water wastage or costs, or have a macerator that wakes sleeping children or dogs that bark if you go to the loo, if you are alone in the house, drink lots of water and have very dilute pee, then make a judgement about what is best in your home and your circumstances.

There's nothing intrinsically grim or unreasonable about not flushing pee every single time. To read all these responses you'd think OP was sharing a single loo with 20 undiagnosed diabetic men and never flushing at all.

wishingonastar101 · 09/02/2026 11:52

If it's just family at home we don't generally flush after a wee. Deffo if there are guests.

My DP also wees in the drain outside our backdoor when he is on work calls (camera off and AirPods in!) - which is revolting really but does save on water flushing and loo cleaning!

wishingonastar101 · 09/02/2026 11:58

I also wee in the shower....

Public toilets smell because of the particles in the air. Flushing creates a plume for around 1 metre (which is why it’s not a good idea to leave toothbrushes out next to the loo at home). You need to let the particles settle to not smell it which won’t work in highly visited loo.
Male and female wee smells different and females have a better sense of smell.
Guide dogs correctly send their owners to the right toilet as they can tell the difference too.
It’s also why unisex toilets stink to women more - women smell the male urine, and the enclosed space with no door gaps and no natural ventilation, concentrate the particles. The enclosed unisex design is more difficult to clean (soaking and drainage) and men don’t aim well. They also don’t wash their hands as much. I am not a fan of the sinks being in the same room as the public toilet because of all the reasons above. Unisex toilets contain more pathogens.
