This is what the toilet on the International Space Station looks like
In 2018, NASA spent $23 million on a new and improved toilet for astronauts on the International Space Station. To get around the problems of zero-gravity bathroom breaks, the new toilet is a specially designed vacuum toilet. There are two parts: a hose with a funnel at the end for peeing and a small raised toilet seat for pooping.
The bathroom is full of handholds and footholds so that astronauts don’t drift off in the middle of their business. To pee, they can sit or stand and then hold the funnel and hose tightly against their skin so that nothing leaks out.
To poop, astronauts lift the toilet lid and sit on the seat — just like here on Earth. But this toilet starts suctioning as soon as the lid is lifted to prevent things from drifting away — and to control the stink. To make sure there’s a tight fit between the toilet seat and the astronauts’ behinds, the toilet seat is smaller than the one in your house.
Toilet paper, wipes, and gloves are disposed of in water-tight bags. Solid waste in individual water-tight bags is compacted in a removable fecal storage canister. A small number of fecal canisters are returned to Earth for evaluation, but most are loaded into a cargo ship that burns up on re-entry through Earth’s atmosphere. Currently, fecal waste is not processed for water recovery, but NASA is studying this capability.
