BAD IDEA
What are the length and width of an airplane bathroom?
Airplane bathrooms are roughly 1.2 to 1.5 meters long and about 0.7 meters wide—basically a tin can, not your palace.
Airplane lavatories are infamously cramped, designed to fit the essentials in a tiny space to save weight and room. Most are about 1.2 to 1.5 meters (4-5 feet) long and roughly 0.7 meters (2-2.3 feet) wide. So, if you were hoping for a roomy experience, you’ll have to settle for the world's most miniature restroom that barely fits a person standing awkwardly. It's less a bathroom and more a claustrophobia test.
