In an era when our wrists and fingers quietly log every heartbeat, step, and hour of sleep, personal health and wellness have never felt more within reach. Watches offer gentle nudges, rings trace recovery curves, and a new generation of bio-curious consumers finally have visibility into patterns once left to guesswork. And yet, even with all this progress, some of our most important biology is now only beginning to come into view.
That’s where spectroscopy comes in, a method that’s used to decode the chemistry of the distant stars. If it can decode something burning millions of miles away, could it also detect the subtle shifts in what we leave behind each day – signals tied to hydration, diet, or even traces of blood? Kohler believes the next leap in personal health builds on its innovation – bringing valuable insights to a space already central to comfort, wellness, and everyday life: the bathroom.
There was just one big problem. With no sleek, compact spectroscopy system to work in a home, let alone a bathroom, the Kohler team had to invent almost every component from scratch. Over the culmination of three years, Kohler engineers, designers, scientists, and health experts collaborated to reimagine the entire system from the ground up, creating a miniature platform that could meet scientifically grounded expectations in the real world.
The result is Dekoda, a small piece of hardware that effortlessly snaps onto the side of the toilet bowl with no wires or tools and gives users health insights in real time. What’s perhaps most surprising about Dekoda is that for all the science, engineering, and patents that went into it, it looks deceptively sleek: a slim, curved module no bigger than the case that holds your glasses. Inside the unassuming device sit advanced optical sensors and custom electronics stacked on an electrical circuit board the size of a credit card.
Dekoda can detect shifts tied to hydration, gut health, and the optical signals of blood in the bowl. But the device itself is only half the story. Kohler built its own tech platform that turns those signals into useful feedback and builds a picture of your patterns over time. Its machine learning models learn your baseline and keep an eye on the shifts that matter, much like a fitness tracker looks at the trajectory of your habits. As Kohler Health CEO Kash Kapadia put it, many people don’t realize how many valuable clues are currently being flushed down the drain. With Dekoda, he said, the goal is simple: “to transform the bathroom into the center of health and wellness.” Adds Nora Tophof, Executive Director and Head of Business at Kohler Health, “We’re putting the power of information back in the users’ hands.”
Because Dekoda is designed to give you greater visibility into your health, privacy is designed into its features. Its optical sensors point down into the bowl, and Dekoda comes equipped with an optional fingerprint sensor for personalized readings in the Kohler Health app. Simply tap your finger and it syncs your data, which is encrypted at rest and in transit. You can choose whether your data can contribute to enhancing the AI that powers Dekoda.
In a way, Dekoda brings the story full circle. The same physics that once revealed the makeup of distant stars is now helping people understand themselves, one ordinary morning at a time. It’s not medicine. It’s not diagnosis. It’s simply a window – quiet, private, and always there – into the countless signals our bodies send and we so often miss. And sometimes, seeing what we leave behind is all it takes to change what comes next.
