The Rise of Health-Tracking Toilets
The bathroom is becoming the newest frontier in personal health technology. Smart toilets, once known only for luxury features like heated seats and automatic lids, are now being designed to analyze waste and deliver medical insights. These devices turn something as routine as using the toilet into a daily health checkup, helping people monitor hydration, diet, and even early signs of disease from the privacy of their own homes.
What Smart Toilets Can Reveal About Your Health
Modern smart toilets collect data from urine and stool using sensors, spectroscopy, and artificial intelligence. They can detect hydration levels by measuring urine concentration, assess gut health through stool consistency, and even identify traces of blood—an early indicator of possible infections or cancers. Some systems also track how often you use the bathroom, revealing patterns that might suggest digestive issues or dehydration.
Users receive their results through companion apps, often within minutes, and can share the data with doctors for follow-up. What used to be dismissed as waste is now viewed as a valuable source of biological information that can transform preventive care.
Leading Smart Toilets and Health Devices
Dekoda by Kohler Health
The Dekoda is the most advanced and widely available health-testing toilet device today. It attaches to any standard toilet and uses optical sensors and AI to analyze waste. Within three to five minutes, users receive insights on hydration, stool quality, and even potential signs of blood in urine or stool.
Data is sent over Wi-Fi to a secure app, where users can download private PDF health reports. The Dekoda uses fingerprint identification to manage multiple users, making it suitable for families.
CEO Kash Kapadia says the goal is empowerment: “People want to take ownership of their health and their wellness.” The Dekoda costs $599, with an optional $7 monthly subscription for continued app access and detailed analytics.
Withings U-Scan
Withings, known for its health-monitoring wearables, is entering the bathroom with the U-Scan, a sensor that clips inside the toilet bowl to analyze urine. It can measure hydration, vitamin levels, ketones, and calcium. This data reveals nutritional balance and kidney health trends that no smartwatch can detect. The U-Scan’s cartridge-based system runs tests automatically, and results are sent to the Withings app.
The device, expected to cost around $379, targets wellness users who want biochemical feedback from daily life.
Toto Toilet With Integrated Stool Scanner
Japanese manufacturer Toto, a pioneer in bathroom innovation, has launched a toilet with a built-in stool scanner. Available since August, it assesses stool composition and frequency to provide digestive insights. This integration marks a step toward combining comfort and health diagnostics in one system. Prices vary depending on configuration, but Toto’s health-oriented smart toilets generally start near $3,000.
TrueLoo by Toi Labs
Developed primarily for elder care and clinical settings, TrueLoo uses optical sensors embedded in the toilet seat to track stool color, shape, and frequency. It can detect changes that may signal constipation, dehydration, or bleeding. The data is shared with caregivers through a secure cloud platform, offering continuous remote health monitoring. Pricing is tailored to care facilities but is expected to expand to consumer markets soon.
Which One Stands Out
Among current options, the Dekoda leads the field in consumer-ready health analysis. It is affordable, compatible with any toilet, and designed for everyday use. The Withings U-Scan will likely become its closest rival once released, offering biochemical data for nutrition and hydration, while TrueLoo represents a major step forward in clinical monitoring for older adults.
Smart toilets bring medical-grade monitoring into the home without invasive tests. Regular hydration checks can prevent fatigue and kidney problems. Early detection of blood in urine or stool can prompt timely medical evaluation, potentially catching illnesses before symptoms worsen. Tracking stool consistency and frequency helps people connect their diets to digestive changes, promoting better gut health.
By turning an ordinary act into a stream of health data, these devices make preventive care as routine as brushing your teeth.
Early adopters describe these toilets as both practical and eye-opening. Users appreciate gentle reminders like “Focus on hydration. Pour yourself a glass of water,” sent straight to their phones. Many see this as the next step in personal health responsibility.
Some experts, however, question the need for such devices until the data becomes more sophisticated. Yet few deny their potential. As one reviewer noted, “You just think it’s waste and you’re flushing it down, but there’s so much that can be uncovered through its analysis.”
The Future of Health in the Bathroom
Smart toilets that analyze waste may soon become as common as fitness trackers. What began with hydration reports and stool analysis could expand to measure hormones, glucose, or microbiome health. The Dekoda and Withings U-Scan show that the future of health monitoring isn’t just wearable—it’s flushable.
These devices are turning the bathroom into a diagnostic lab, redefining what it means to keep an eye on your health—one flush at a time.
