I like those bristley p-wave inserts. They’re actually really clever, they stop almost all of the splashback, which means the men’s room doesn’t smell of piss - also that there isn’t so much piss lingering in the air for you to breathe.

I look forward to the day that I see a urinal covered in those bristley things, like a 70s Cadillac.

I might be mistaken, but I think it is there to avoid the smell of urine.

It’s to reduce odor, though I have no idea why one has ice and the other doesn’t

Piss ice is so satisfying. You get to see your stream melt the ice and steam comes off. No splashback. No flushing. Fuck yea, piss ice baby!
