Imagine getting a daily health checkup without ever leaving your bathroom. That’s exactly what Withings promises with its latest innovation, the U-Scan — a smart toilet device that automatically analyzes your urine to reveal key insights into your nutrition, hydration, and kidney health.
After years of development, this discreet gadget brings lab-grade science straight to your toilet, helping you detect potential issues like kidney stones before they strike. Keep reading to discover how your next bathroom break could be the key to better health.
Withings turns your toilet into a smart health lab with U-Scan
After more than seven years of rigorous research and innovation, connected health pioneer Withings is unveiling its most groundbreaking creation yet — the U-Scan, a compact urine analysis laboratory designed to fit seamlessly inside your toilet. This first-of-its-kind device combines advanced chemistry, optics, and artificial intelligence to provide real-time insights about your health directly from your bathroom. Launching in Europe and the United States on October 29, the system debuts with two models: U-Scan Nutrio and U-Scan Calci.
Already honored with 12 innovation awards, the U-Scan marks a leap forward in everyday health monitoring, transforming an ordinary routine into a powerful tool for continuous biological tracking.
“The story of U-Scan began with a simple intuition: urine provides a precise and comprehensive window into our health,” Eric Carreel, founder and chairman of Withings, shared in a press release. “The challenge was to transform that insight into a laboratory so compact it could be integrated directly into a toilet — without changing anyone’s habits.”
Urine offers a wealth of information about the body, containing more than 3,000 metabolites that reveal details about hydration, nutrition, metabolism, and hormonal balance. Despite its potential, this treasure trove of data has traditionally been limited to infrequent lab tests, until now. Withings’ U-Scan eliminates that gap, embedding laboratory-grade analysis directly into the toilet to make preventive health tracking effortless, discreet, and continuous.
How does the U-Scan work?
The U-Scan is designed to blend effortlessly into your toilet, transforming a simple bathroom visit into a smart health check. Using a sensitive thermal sensor, the device automatically detects and collects urine samples without any user intervention. Each sample is then analyzed instantly using miniaturized biochemical sensors housed within an interchangeable cartridge, delivering lab-quality data right at home.
In just a few minutes, the results are processed on the device and securely transmitted via Wi-Fi to the Withings app, where users can view detailed insights on hydration, nutrition, calcium levels, and more. The app goes beyond raw data, converting readings into personalized recommendations and health trends through Withings+, empowering users to make informed lifestyle adjustments.
Every cartridge provides up to three months of continuous testing, depending on frequency, and can be replaced effortlessly when needed. Between sessions, the U-Scan connects to a dedicated charging and cleaning station, fully refreshing the reader in as little as three hours, keeping your smart health lab ready for its next analysis.
U-Scan Nutrio tracks your body’s nutritional balance
One of the two models in Withings’ groundbreaking U-Scan lineup, the Nutrio version provides a data-driven view of how your body responds to nutrition, a feature that traditional lab tests rarely capture. By analyzing urine chemistry daily or weekly, it measures four key biomarkers: Bio-Acidity (pH), HydroStatus (specific gravity), Ketones, and Vitamin C, to reveal insights about diet quality, hydration, fat metabolism, and antioxidant levels. This continuous monitoring transforms occasional lab snapshots into real-time, actionable health insights.
Powered by intelligent algorithms, U-Scan Nutrio detects subtle metabolic patterns that can help users fine-tune their diet and performance. It also supports those undergoing GLP-1 (glucagon-like peptide-1) transitions, a process linked to the use of GLP-1 medications such as semaglutide, which help regulate appetite and promote weight loss. By tracking daily biochemical responses, the device helps users understand how their body adapts to these changes, while the Withings app visualizes data and delivers personalized guidance for improved balance and recovery.
U-Scan Calci monitors your kidney health in real time
Meanwhile, the other model, the U-Scan Calci, focuses on helping users take a proactive approach to kidney health. Since kidney stones affect about one in ten adults worldwide, most often due to high urinary calcium levels or chronic dehydration, Calci continuously monitors three crucial biomarkers: calcium levels, Bio-Acidity (urinary pH), and HydroStatus (specific gravity).
By analyzing these readings in real time, the device can detect early warning signs of stone formation, such as elevated calcium excretion or imbalanced pH levels, while also tracking hydration to maintain optimal urine dilution. In doing so, U-Scan Calci shifts kidney care from reactive treatment to preventive monitoring, bringing clinical-level insights right into the home.
U-Scan debuts with flexible subscription plans
Health tracking from the comfort of your bathroom becomes a reality this fall as Withings’ U-Scan Nutrio and U-Scan Calci officially launch on October 29, 2025, across Europe and the United States, exclusively through withings.com.
The device will be offered through two flexible subscription options tailored to different wellness goals. The Proactive Plan is priced at $379.95, providing 2–4 analyses per week, one cartridge, and full access to Withings+ insights. For users seeking more frequent monitoring, the Intensive Plan is available at $449.95, featuring 5–7 analyses per week, two cartridges, and complete Withings+ access.
