World Toilet Day is a serious affair. One in five primary schools and one in eight secondary schools in the world do not have any toilets, according to WaterAid. An estimated 4.5 billion humans do not have access to proper sanitation, and 2.5 billion do not have adequate toilets.

But for those of us lucky enough to shop for toilet paper at Walmart ($WMT), here are the 50 most-popular brands and versions of toilet paper sold at the world's largest retailer.
