In my Scandinavian country, we don't have a "poop shelf" either. But we don't use the American design with a huge amount of water in the bowl.

It's has a small amount of water at the bottom that receives our "output". There are also no problems urinating as it is easy to either hit the water or the porcelain wall at the bottom, that are much more vertical. Most of the accidental splashes that occur are either because the man is drunk and can't hit the toilet, or that the foreskin is pulled a bit back and doesn't contain the stream as well as it should.

lower-calorie, higher-fiber european poops don't generally reach the size of american fast-food poops. but everyone loves the feeling of breaking the surface, so to promote a sense of social well-being some countries have artificially lifted the poop instead.

(the above is false, but it is unironically there so that you can look at your poop. admire the shape, the volume, the coloration. and just wait until you learn there's an easy at-home diagnostic test for diabetes mellitus!)
