Ever since toilet paper became a luxury good for a hot pandemic moment, it feels like ads for simple, affordable, and sometimes chic bidets have flooded our newsfeeds. The aesthetically pleasing, booty-washing basins come with claims of being cleaner, better for the environment, and easier on the wallet over time. 

The jury is still out on how necessary bidets are for cleaning every last bacterial cell off your backside—but for folks with especially itchy bottoms, one study has shown that the water jets can reduce irritation. But for the more general population, the sustainability aspect of spritzing after a poo is likely the real draw. And there are still a lot of unanswered questions in that department, too.
