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.

    I can see some commenters are confused. The water only runs whilst the cistern is being filled after a flush. It will be cold water and only so you can wash your hands after using the toilet, not for you to brush your teeth or wash your face. If you use a gel liquid hand soap it won’t get all scummy inside the cistern after you wash your hands.

    This is only for handwashing after using the toilet. Nothing more.

    My family has one of these for my whole life (USA) and we’ve had to explain to so many people that you’re not washing your hands with toilet water.

    We have one of these 🙂 we’re in England.

    Great idea, until you pour something down the sink, like a coffee and then forget. Then when you flush the toilet later you panic wondering why the water is brown 😅

    Do people straddle the toilet in order to wash their hand?

    How do short people, and kids reach the sink?

    Wouldn’t it be more hygienic and easier to use to just have a pipe from a regular sink to the toilet. Same concept of using the water just a meter apart for ease of use

    Went to Japan in 2019 for a week. Although their toilets are amazing, I did not see this type once.

    The toilets did have a built in bidet, heated seat, and a retractable wand that popped out to pressure wash the hershey highway along the back side.

    Controls right next to the toilet on wall including a #1 or #2 flush and additional ways to control spray wand.

    All public toilets were also like this and were *pristinely* clean. **Even the subway ones.**

    I’m such a baby, I want warm water, but this is genius.

    My back hurts already

    I was going to buy one of these, turns out they’re very expensive.

    I have this same thing on my toilet at home. I live in Kansas City (where everything is up to date).

    I save water by peeing in the sink.

    I do it everywhere. If I’ve been to your house, I’ve peed in your sink. Restaurant with a private bathroom? Pee in the sink.

    I can’t help myself at this point, it’s an addiction.
