Wouldn't it be the taller the toilet, the more splash you'll have, as it needs to fall further before reaching the water?

The toilet:

You thought

what, you do not enjoy the Witch's Kiss

Challenge accepted. Good luck to the measurement team.

I might be wrong but splashback seems to be a purely American problem. European toilets tend to have a much lower water level (and I'm not even talking about those old-timey poop shelf toilets). In my well over 30 years of using toilets, I barely remember ever getting splashed.

I just leave the bowl empty of water, then flush with a separate bucket I fill from the bathtub tap.

Sure, the bowl is covered in shit stains, but at least I don't have to experience Poseidon's Kiss.

Just use a suction hose astronaut style.

Doubt that would accomplish anything but I am surprised we cant apply modern CAD/simulation tech and ML… hell any modern tech to possibly design a toilet bowl that deflects piss and doesn’t allow shit to cling to it like a 3M glue.

With modern material science and rapid prototyping I am disappoint.

The Dutch have already solved the splashback question but the world was not ready for their solution.

We don't need to measure. Just make it double the height based on the terminal velocity in 1atm

you need the opposite. small enough space that its mostly in water before the pinch. just don't have the squirts.

Turdminal velocity is an important consideration.

There are toilets that have a shitshelf, no splash ever. Stains are more likely, but a layer of tp or a quick post-partum brushing does the trick. Small price to pay for a dry bum.

The splash is a free bidet

Except the velocity varies.. sometimes you get the slow rollers other times the super sonic projectile and then there are snapping turtles.. they poke out a head and go back in.

The sceptic in me says kinetic energy down = kinetic energy up

i've never been splashed, American toilets have the cistern in the bowel to deliberately splash you, it's punishment for not moving to the metric system.
