They're pretty common in Russia, too. In Muslim countries they're basically everywhere.
When you're used to them it's very annoying to end up in a country that doesn't have them. Especially the US, which in addition has strange toilets that fill up with a lot of water during normal operation and bathroom stall privacy that begins 30cm above the ground.
Not even close. Try to travel in Latin America or something and go to a bathroom. You won't find toilet paper or a toilet seat, or even free bathrooms in many cases.
Not always — I was pretty surprised they didn’t have them in every bathroom when visiting Morocco. My family is Algerian and they’re standard there, and I always assumed it would be common in other Muslim countries considering how much emphasis there is on cleanliness, but I didn’t encounter a single one the entire time I was in Morocco, across four cities.
I feel it’s weird defining them by the main religion of the country it is (maybe) mostly used. No one says the numbers used in English are Muslim, they are generally referred to as Arabic.
I wouldn’t say printing is a “catholic thing”, but it definitely came from a super catholic part of the world.
Mainly because Islam has jurisprudence around hygiene in a sense. Ritual purification is an actual religious principle.
Islam requires Muslims to pray 5 times a day, and for those prayers, one has to be ritually clean. That involves washing the hands, rinsing the mouth and nose, washing the face, forearms, head, ears, and then the feet. That's effectively all the major parts of the body that are generally not covered by clothes. Your "cleanliness" is invalided if you use the toilet, pass flatulence, vomit, sleep and so on.
More so, for using the toilet, there are rules. You have to find a place that is away from standing water, people's pathways, shade etc ; granted, this generally doesn't apply in today's age. You have to be quiet on the toilet, and not look at anyone. Not allowed to eat any food while defecating. Lastly and most relevant in this case, you have to use water to wash yourself using the left hand, and then afterwards, you need to do the same for washing the front if you've urinated.
The reason why the "bidet spray" thing exists, is largely because of the rules in the religion around that practice. Calling them Arabic wouldn't make any sense because Indonesia, with the largest Muslim population, has similar tools in their facilities. Again, because they're mostly Muslims.
Printing isn't a catholic thing because the religious doctrine didn't emphasis "printing" itself.
Arabic numbers aren't "islamic numbers" because the religious doctrine didn't emphasise the numbers in some way.
> After defecating, the anus must be washed with water using the left hand, or an odd number of smooth stones or pebbles called jamrah or hijaarah (Sahih Al-Bukhari 161, Book 4, Hadith 27).
