When I started my career, I never thought I would spend so much time talking about corporate bathrooms. But the truth is people feel passionately about them. They might be the most underappreciated and most necessary spaces in the workplace. Everyone has to go there (no giggles please), and the experience usually falls somewhere between bland and horrifying. It’s no wonder that so many people I talk to on projects—from executive leaders to employees—bring up bathrooms as one of their top complaints.
