It says for married couples but if you're living together that counts too. I live with my SO and our bathroom is out in the hallway and we poop with the door open lol. It doesn't bother us and since the bathroom is down the hall smells really aren't an issue. Now like if I'm having a horrible night accompanied by dirrhea i shut the door, but for my normal 2 minutes poops I don't. He walks by sometimes like "sup" 😂
