Methodology:

To determine the bath, shower and bidet hotspots around the world, we calculated the percentage of hotel bookings in each country, state and city that have showers, baths or bidets.

We used Booking.com to determine the total number of accommodations (hotels, apartments, holiday rentals, etc.) in each geography and then found the number of accommodations in each geography that have either baths, showers or bidets using Booking.com filters.

I was unable to find an option for "baths, showers, or bidet" in the booking.com filters, let alone options for each of those individually. So I'm not sure about the exact data used for this infographic.

The 38% for Japan seems suspect to me. I found this online from a commercial site, but the number is closer to my experience: "Bidet Toilets and Japanese Culture High-end Japanese-style toilet and bidet combinations might retain a degree of exoticism in the US, but they’re extremely common in Japan. According to NPR, roughly 80% of Japanese households own a bidet, and you’ll find fancy Japanese toilets in most public areas as well. "

Get a bidet! You wouldn't wipe poop off anywhere else on your body with paper and feel clean about it

Have my doubts about the accuracy of the data. Bidets of the handheld type are very common in Malaysia.

Just got one of these and it's such a life upgrade. Has an anti stink function, too. Filters the air through activated carbon, which means unless you are dumping something extra nasty, there is not even any smell afterwards. And my bottom never felt this clean before.

so this tells us the italians have the cleanest asses.

Some ~30 years ago bidets were extremely common in Brazil; I don't have data, but it was way higher than the current 6.6%.

I feel like this is because, nowadays, toilets are made for ants. No space for a bidet or a bathtub - only shower, sink, the loo itself, and the door between shower and the rest. (Plus fixture that doesn't take space, like a mirror.) Demographic concentration got way overboard in the large cities. Plus those mini handheld showerheads became way more common, if you do need a bidet those are a decent sub.

...I have mixed feelings about this. I don't care about bidets, but I get pissed (pun not intended) because of why they're gone.

Japanese toilets.

Some countries don't have the plumbing to handle toilet paper, so they might use bidets or... buckets of water and a ladle. Not sure if that counts as a bidet or not.

26% in Finland is bullshit. I have never seen one here or heard anyone talk about them.

Most people do have these hand showers that you can use to wash your ass / toilet / sink

Bidets are mandatory for serious cyclists.

Difference between Japan and Korea is only 1%??? I don't even remember seeing non-bidet toilet in Japan.

when they are used in those countries that use them the most, d’you think everyone bursts out singing, “happy bidet to you!”?

In Australia, they were (and possibly still are) illegal, on the grounds that the possibility of fecal matter making its way back through the plumbing into the public water supply is theoretically nonzero.
