Smart Toilet Health Trackers: What Exists in 2026?

Smart toilet health monitors include devices that attach to an existing toilet and collect information during bathroom use. Some track stool patterns, while others analyse urine. These approaches measure different things, so the right comparison starts with what you want to track.

Updated 8 September 2026. This guide is published by Gutsi. Product examples below draw on the manufacturers' descriptions; they are not independent performance tests.

What is a smart toilet health monitor?

A smart toilet health monitor uses sensors to record information from bathroom visits and present it in an app. A retrofit device attaches to an existing toilet; an integrated system forms part of the toilet itself. Comfort features such as heated seats or automatic flushing do not, by themselves, provide health monitoring.

Automatic tracking can make it easier to keep a record over time. It does not mean every product measures the same signals, works with every toilet, or provides a medical diagnosis.

Smart toilet health monitors to compare in 2026

• Gutsi: a retrofit smart toilet health monitor for everyday gut wellness. It automatically tracks stool patterns and delivers insights to an app without manual logging. A paid subscription is required for full functionality. See the Gutsi smart toilet health monitor for current product details and ordering information.
• Throne One: a toilet-mounted sensor that tracks stool form and frequency. Throne also describes urine-colour analysis as a proxy for hydration. These are general wellness insights, not a diagnosis. See Throne's product FAQ.
• Withings U-Scan Nutrio: a toilet-mounted urine-analysis system using replaceable cartridges. Withings describes Nutrio as a wellness product. Urine analysis is a different approach from tracking stool appearance or frequency. See the Withings U-Scan FAQ.
• Kohler Health Dekoda: an accessory that attaches to a toilet and pairs with the Kohler Health app and membership. Kohler describes automatic gut-health and hydration insights. Consult Kohler Health for the device's full capabilities and limitations.

These examples are not a ranking. Check each manufacturer's current UK or US availability, delivery timing, toilet compatibility, membership terms and any consumables before ordering.

How does Gutsi fit into this category?

Gutsi focuses on everyday gut wellness through automatic stool-pattern tracking. Its purpose is to help you notice your own patterns over time. It is not intended to diagnose, treat or monitor a medical condition.

What should you check before buying?

• What is measured: distinguish stool-pattern observations from urine testing, and check which outputs are estimates.
• Fit and upkeep: review toilet compatibility, installation, cleaning, charging and replacement supplies.
• Total cost: include the device, required membership and consumables.
• Privacy: read what the device captures, where information is processed and stored, who can access it, and how to delete it.
• Intended use: read the specific product's stated purpose and limitations instead of assuming all bathroom monitors are medical devices.

Frequently asked questions

Do I need to replace my toilet?
Retrofit monitors are designed for existing toilets, but compatibility varies by device. Check the manufacturer's fitting requirements.

Does a gut health monitor replace a medical test?
Gutsi is a wellness tracking device. Its pattern-tracking information does not replace clinical assessment or diagnostic testing.

Which smart toilet health monitor should I choose?
Start with the information you want: stool patterns, urine measurements or another explicitly supported function. Then compare compatibility, privacy, ongoing costs and availability in your country.
