American bathroom brand Kohler has released Dekoda, a toilet-mounted health tracker through its spin-off Kohler Health. The device clips to the side of the toilet bowl to provide insights on gut health, hydration levels, and detect blood.
“When we developed Dekoda, our goal was to give people the tools to listen to their bodies, track meaningful results over time, and take charge of their own wellness journey,” said Kohler Health managing director Nora Tophof. “It’s important to realise that the human eye is only capable of seeing so much – and trace amounts of blood or other issues are not always apparent.”
“Subtle biological markers, such as microscopic blood or early signs of dehydration, often go unnoticed,” Tophof continued. “Dekoda works quietly behind the scenes to capture those crucial clues, giving people clear, objective data they can use to help shape behaviours or share with their doctor.”
The device is designed for individuals with chronic gut illnesses or older adults, as well as competitive athletes. Dekoda uses sensors developed at Kohler Health to identify haemoglobin, making it the first toilet-based health tracker capable of blood detection in the emerging market.
Dekoda attaches to the outside of the toilet rim with an adjustable clamp and features a camera and optical sensors pointing into the bowl. It uses spectroscopy to detect the quantity, colour, and consistency of urine and stool. The device is made of antibacterial polycarbonate and stainless steel, with a magnetic battery that can be removed for charging.
Users log in via a wall-mounted fingerprint scanner and view insights in the Kohler Health app. The app automatically tracks bathroom routines and allows users to add context about meals, medications, and exercise, with data encrypted during transfer to Kohler’s systems.
Kohler Health released Dekoda in October 2025, positioning it as a tool to help destigmatise the collection of gut health metrics.
