Barney Smith's Toilet Seat Art Museum
San Antonio, Texas
Proving that anything can be a "museum" if you fill it with the right stuff, master plumber/artist Barney Smith has bejeweled his garage with ornately decorated toilet seats. And not like the pink, frilly carpet your grandma decorated hers with. Smith's seats are covered with legit stuff: railroad spikes, maps of the world, original paintings. Though it's absolutely unlike any other art museum in the world, if you want to actually learn about toilets, you're going to have to travel a little further.
Sulabh International Museum of Toilets
New Delhi, India
New Delhi is one of the best places in the world to see how people disposed of waste before the advent of flush toilets. It's also home to this museum, where you'll learn about the 4,500-year history of human waste disposal, as well as see some of the most extravagant, unusual, and spectacular toilets in history. It's part toilet education and part social statement, as the founder created the museum as a way to educate Indians on the importance of public sanitation.
