Welcome to the 70's-80's when carpeting was de rigueur for bathrooms and kitchens.
Fun story ... my son was a climber so all food was in the highest cupboards. One time I needed a bathroom break, and in under 5 minutes he'd dragged a kitchen chair to the counter, climbed up, took down the flour and dumped it all over his little sister. Honest to gawd all I could see of her was her dark eyes in a cloud of white.
And just to boost his creativeness here, he decided to move the chair to the sink, grabbed a cup of water and they started making flour pies on the carpet.
Whenever a man is peeing standing up, droplets will spread around the toilet. Over the years, the buildup will be horribly unhealthy and disgusting. But for Brits who already never wash their hands, it may not be such big of a deal.
Then just don't pee standing up, I'm a dude and when I'm at comfort of my home I always choose to sit on my toilet. It's so much better that way, much more comfortable and less messy.
