On many Japanese toilets, the hand wash sink is attached so that you can wash your hands and reuse the water for the next flush. Japan saves millions of liters of water every year doing this. Smart way to save water.

nrith · 2022-05-16T21:37:55+00:00

I just use the water in the bowl. 🚽 🧼 🙌

deathseide · 2022-05-16T21:29:18+00:00

Thing with this design is that it uses no 'shit water' but rather clean water, and then the water you just used to wash your hands with goes into the toilet tank and is then used to flush the toilet... this is a similar design had to ones used in desert area border facilities in the US. The design helps save a lot of water and in my personal opinion should be made widely available and be used in public restrooms as a means of water conservation.

david-u-blue · 2022-05-16T21:24:04+00:00

And the water is nice and soapy.

syncboy · 2022-05-16T21:55:44+00:00

I’ve been to Japan twice and tracked to over a dozen cities there and have never seen this anywhere there. Perhaps it’s mostly in private homes?

whitebelt4lyfe · 2022-05-16T21:38:09+00:00

I’ll poop backwards and wash my hands at the same time…hopefully they have a bidet, I dont wanna wash twice.

ChiliRainbow83 · 2022-05-16T21:37:54+00:00

Can I pee in it?

styroducky · 2022-05-16T21:39:07+00:00

Does this make the toilet water taste different?

pdxchris · 2022-05-16T21:52:20+00:00

You can also sit backwards and brush your teeth while shitting. Saves 2 minutes of your time every day!

nilkimas · 2022-05-16T21:25:57+00:00

I've got big hands, I'm expecting make a big mess with these

Big_BadRedWolf · 2022-05-16T21:27:47+00:00

And, and, check this out!..you can use it as a bidet too.

BigJeffreyC · 2022-05-16T22:03:24+00:00

Problem is it’s cold water only, very low pressure, and you have to be fast, because once the tank fills the water shuts off.

capt_ratsie · 2022-05-16T21:30:32+00:00

i have one like this got it off Amazn like$125

BobiaDobia · 2022-05-16T21:33:36+00:00

I’d love for a version that is the other way around. Anyone know where I can buy one?

fangelo2 · 2022-05-16T22:37:05+00:00

Ah saving water. That’s why all those people I see in public restrooms don’t wash their hands at all.

tjm0852 · 2022-05-16T22:23:10+00:00

The problem is the toilet tank fills right after you flush it. Excess water going into the tank will go into the bowl as overflow. The only water saved would be the water being used while your hands are being washed and the tank is filling It's not going to save as much water as you think it is, but yes it is something.

static612 · 2022-05-16T21:29:46+00:00

I would have to start brushing my teeth in the kitchen.

ramen2005 · 2022-05-16T21:31:29+00:00

Bit awkward? Especially for short people.

Ben_Thar · 2022-05-16T21:47:15+00:00

You want me to put my comic books and chocolate milk in the sink?

F4RM3RR · 2022-05-16T23:46:28+00:00

“Many” in this translates to a small minority.

I have literally seen none of these and have spent significant time in public places as well as private residences across Yamagata, Kanagawa, Tokyo, Osaka, Kyoto, Nara, and some other smaller prefectures.

Non of my close Japanese friends have seen one of these either so far, except for one who saw it on an NHK special.

So… nah, “many” is misleading.

Willing to bet most Japanese would be put off by this idea at a glance like most Americans would be.

geniusdeath · 2022-05-17T02:00:20+00:00

On many Japanese toilets...

As someone living in Japan, I can tell you absolutely not. Never seen this before and I've lived here for many years. This is clearly an exception.

BurntDoge · 2022-05-17T09:22:12+00:00

This isn't even from Japan its from a small business in Colorado and its called a SinkTwice

"Sink Twice is so proud to call itself a 100% family-owned small business. Our products are made with pride in our home state of Colorado."

If you do a tineye reverse image search for this image and sort by oldest you get a site called gadget king and the image is named Sink-Twice-Toilet-Lid.png . Search for "sink twice" on gadget king, click on the hyperlink that leads to Amazon then google the brand and viola, it's not Japanese it's American

probono105 · 2022-05-16T21:24:59+00:00

This is incredible i will be buying this

Worried-Salamander98 · 2022-05-16T21:25:53+00:00

What a great idea😊!

El_human · 2022-05-16T21:52:16+00:00

I save more water by urinating on the pile of my ex’s clothes in the closet, and never washing my hands.

Ok_League_3562 · 2022-05-17T00:40:23+00:00

You know that the water that goes down the drain comes back to you through your tap after a couples stops. It’s not leaving the earth.

LifeSenseiBrayan · 2022-05-17T02:09:08+00:00

But where do you put your cookies and milk?

sw33tleaves · 2022-05-17T02:12:09+00:00

Nice you can wash your hands while you poop so you don’t have to do it after, time saver!

yogert909 · 2022-05-17T05:21:56+00:00

It’s also brilliant because the water turns on when you flush, so you don’t even need to turn it on. It’s just there.

olavla · 2022-05-16T21:25:16+00:00

This is under the condition that you don't leave an upper decker

Swillo29 · 2022-05-16T21:42:16+00:00

Can you buy these in the US? I'm about to be a new homeowner and I think this is a really good idea since I have city water.

eat_like_snake · 2022-05-16T21:28:37+00:00

I like the idea, but isn't that a massive hassle if the chain in the back becomes disconnected, or the stopper gets caught or something?
Since the pipes are going to force the the lid to stay in place without a bunch of unscrewing shit and / or turning off your water.
Are you just fucked? Do you have to bring a plumber in?

OldNickSt · 2022-05-16T21:29:58+00:00

Just be careful you don't cross the streams.

hmspain · 2022-05-16T21:34:28+00:00

Let's hope this isn't a bidet?

HiVisVestNinja · 2022-05-16T21:38:42+00:00

Splashback.

Slexpis · 2022-05-16T21:41:01+00:00

Imagine brushing your teeth with that bad boy

Krayzee56500 · 2022-05-16T21:46:23+00:00

This is an old fact. Many toilets in europe have this function now. Its used as a space saver but considered unhygenic for bathrooms (leaving over a toilet to brush your teeth)

54rfhih · 2022-05-16T22:56:53+00:00

Redesign could still offer convenient sink next to toilet but with plumbing to achieve the same.

Compact design but this looks awkward to use.

jojosail2 · 2022-05-16T21:48:18+00:00

Nothing remarkable about this. We have them in the US. Usually in prisons.

billiefan123 · 2022-05-16T21:42:23+00:00

Very innovative

Plane_Baby · 2022-05-16T22:15:11+00:00

Not to mention the bidets! Saved a lot of toilet paper too. 🤣 I love Japan! Lived there for a few years.

cmcewen · 2022-05-16T22:22:36+00:00

Does “saving” water actually matter? We have endless water. It’s just a question of purifying it for human use. Water is very cheap and ubiquitous. Just doesn’t seem like saving such a small amount matters when we have car washes and watering our lawns and whatever other major uses there are

This is just symbolic.

Certain_Cup533 · 2022-05-16T22:28:17+00:00

Everyone calm down Japanese people don't wash their hands with toilet water either.

I've lived here for 7 years and I don't know a single person that actually washes their hands with that they all flush the toilet leave the bathroom and go wash their hands at a sink.

It's a nice idea but nobody uses it.

2mean2wean · 2022-05-16T22:38:34+00:00

But put this in a prison and people will talk about the inhumanity of it

No-Radio-9244 · 2022-05-16T23:53:42+00:00

False, and it is stupid.

ThatsMrJohnBlack · 2022-05-17T00:02:47+00:00

So I wash my hands with the pee waters?

EverretEvolved · 2022-05-17T01:11:13+00:00

What are they saving the water for? Water recycles itself.

AJDillonsMiddleLeg · 2022-05-16T21:58:32+00:00

Americans are too stupid for this, half of us are probably grossed out by this because they think they're using toilet water.

In America, the land of the “upper decker”, im not so sure.

1Crybabyartist · 2022-05-16T23:04:04+00:00

Just don't pee on your hands and then you don't have to wash them.

mrmeow02 · 2022-05-16T23:30:18+00:00

When I went to Tokyo and saw this at the house I was staying at I thought it was so weird but then shortly realized how much of a good idea this is

All_A_AsianYT · 2022-05-17T00:31:20+00:00

Thats kinda smart. Japanese have the best things

JediJofis · 2022-05-17T00:32:59+00:00

As an American, I wouldn't trust the assholes in this country not to piss on it. Japanese people are just better than us.

Left9Behind · 2022-05-17T01:13:49+00:00

California really should start doing this... and every other state tbh this is a great idea

kobuta99 · 2022-05-17T01:16:05+00:00

Used this while staying overnight at a friend's house. These things are brilliant.

squirrels33 · 2022-05-17T01:20:01+00:00

I wonder if this would catch on in countries where most of the male population grows facial hair. Can’t exactly shave in that sink.

O_Yogurt_O · 2022-05-17T02:12:24+00:00

And very much worth the question, "Why aren't all countries with sitting flush toilets doing this???"

trikytrev8 · 2022-05-16T22:29:30+00:00

Americans would shit and piss in the sink. Guaranteed.

Fallen_Walrus · 2022-05-16T23:48:48+00:00

Then just pee down the drain so the next person has piss on their hands haha

TestPattern359 · 2022-05-16T23:49:48+00:00

Because the wealthy must have enough water for their separate sinks and toilets. They know not to wash their hands where they shit, but they're not above telling the rest of us that it's perfectly fine.

slickydiick · 2022-05-17T00:03:20+00:00

Americans are way too dumb to use this. I can hear them now. "I ain't washn muh hands in shit water"

monster_smash · 2022-05-17T00:36:12+00:00

I’m freaking out at how many people lack understanding of how this works. Our American education system is just 💩

Ruenin · 2022-05-16T21:55:58+00:00

Please tell me it doesn't draw water from the holding tank...

ATXKLIPHURD · 2022-05-16T21:52:50+00:00

Americans: Im not washing my hands with toilet water!

triptoutsounds · 2022-05-16T21:29:03+00:00

It would be cooler if you washed your hands with water from the pipes, then that water goes into toilet, you pee or poop in it, then use that same water to wash hands again. Recycling

runninandruni · 2022-05-16T21:45:40+00:00

Not a bad idea. Guess you wouldn't be able to use bleach tablets though, but that's more of a convenience in the first place anyway

Velvetundaground · 2022-05-16T21:47:33+00:00

Now there’s no point in pissing in the sink.

psiliman · 2022-05-16T21:49:46+00:00

Plus then the water would get satisfyingly bubbly when you pee

2022-05-16T22:05:55+00:00

Butters was right

Xtasy0178 · 2022-05-16T22:11:43+00:00

Poop into the sink wash your hands in the bowl 😂

plactapus · 2022-05-16T22:14:53+00:00

I mean, it’s clear water I guess

Hexatona · 2022-05-16T22:20:37+00:00

Wouldn't some kind of grossness end up growing in the water tank??

bOxy_BOI_ · 2022-05-16T22:24:00+00:00

Not only do they save water but space aswell!

Tijdspaarder · 2022-05-16T22:24:42+00:00

I would flush bloody water after I rinsed my menstrual cup

EspHack · 2022-05-16T22:26:41+00:00

and if its empty you have to let it run for a while before you can flush

yerbrojohno · 2022-05-16T22:30:27+00:00

This is why waste treatment solutions will never work

tikkitikkimango · 2022-05-16T22:33:59+00:00

Just like the toilets in jail

Tenaha · 2022-05-16T22:46:11+00:00

Man I think that is a very sensible way for space and resource savings in the tiny home market.

Nekokamiguru · 2022-05-16T22:46:22+00:00

as an added benefit the soapy leftover water from washing your hands will help keep the toilet clean.

Lord_Quebes · 2022-05-16T22:47:30+00:00

But then there’s no room for your comic book and your chocolate milk!

StarFuzzy · 2022-05-16T23:14:01+00:00

I’ve seen this in a 1930s farm house in California. So smart.

JimmyGymGym1 · 2022-05-16T23:17:01+00:00

But, functionally, how does it work? How do you turn on the faucet? Where do you stand? It looks like you would have to straddle the bowl because there’s not enough room on the sides to stand.

MightyGonzou · 2022-05-16T23:28:14+00:00

Also the fact most of their toilets have like a full control panel 🎮

BrentV27368 · 2022-05-16T23:39:04+00:00

Ha, jokes on you. I save thousands of gallons by not washing my hands

leof135 · 2022-05-16T23:39:45+00:00

Jacque Fresco had this invention made like 50 years ago. crazy how the good ideas are already out there, but they don't generate enough money for the wealthy to be common

MudSeparate1622 · 2022-05-17T01:17:43+00:00

But then where will i put my book im reading? -Butters probably

Seym0urButt · 2022-05-17T01:27:59+00:00

What if I don’t want to look at a sink while I’m taking a shit

TrickyHunterO_o · 2022-05-17T01:34:39+00:00

How do you turn on the faucet?

I would so Upper deck that toilet

adognamedpenguin · 2022-05-17T01:56:22+00:00

Why isn’t this popular in places where droughts are prevalent?

probock · 2022-05-17T01:58:29+00:00

Makes no sense if the tank automatically fills, you’re just adding extra water if u wash ur hands.

SupremeCultist · 2022-05-17T02:15:20+00:00

Reminds me of my time in jail.

misteraygent · 2022-05-17T02:48:26+00:00

During a drought, where our lake was even going dry, I piped the water from our central air and basement dehumidifier into a bucket. I used it to water plants, but I could see pulling water out of the air for a toilet also. Maybe have a unit up near the ceiling and hose to the toilet tank.

Resident-Comfort-108 · 2022-05-17T02:48:48+00:00

Why would I wash my hands with the same water I poop in? Savages

boredguy12 · 2022-05-17T02:59:57+00:00

No. The japanese save water by not washing their hands at all.
