This is what people are used to here...a squatty potty.
You stand over top of the opening and put your feet on the ridged foot pads so you don't slip and fall!
I still have not had to use one of these, but it's not because European toilets are more common, it's because I don't drink much when I'm out and about. If you put dehydration and using these toilets on a scale...you can see which one would win out.
Although I have found a trick. If you can drink 2 liters of water 2 hours before you leave you can use your own facilities before leaving, and not need any water for quite some time---hopefully till you return home.
The most noticeable thing about these toilets is the smell. You can literally smell them from a mile a way and you can use your nose to find them if you find yourself needing to use it.
Usually restaurants that cater to foreigners will have a normal looking toilet...but they don't always have toilet paper--actually mostly they don't.
But they do have this...
Yes, I'm still not quite sure how you would use this without looking like a wet dog after, but you do what you have to do I suppose!
So usually when you pack your bag before leaving somewhere you always BYOTP!
If a place does have it's own TP for you to use, always make sure it is near the toilet. A lot of times it's way over by the door, and that kind of defeats the purpose!
Yes, getting used to a new culture can be challenging at times, but so far nothing we can't handle with a little foresight!
