Throne vs. Kohler Dekoda: Which Bathroom Health Tracker Is Better for You?

Your toilet probably isn't the first place you'd expect to learn about your health. But that's the idea behind Throne and Kohler's Dekoda. Both devices attach to your toilet and analyze stool and urine to give you insights into your gut health and hydration.

But there are some important differences in how they work and what they tell you.

Throne tracks bathroom visits automatically, classifies stool using all seven types on the Bristol Stool Scale, and measures urinary flow. Dekoda requires you to identify yourself before each visit and uses three broader categories for stool consistency.

So which one is the better buy? We compared the research behind both devices, their features, everyday usability, privacy, and pricing to see how they stack up.

Which Device Has Published Accuracy Testing?

Throne has published an initial evaluation of its stool-form classification. Comparable public validation results for Dekoda were not identified for this comparison.

Throne's first clinical validation study was presented at the 2026 American College of Gastroenterology Annual Scientific Meeting. Five board-certified gastroenterologists and Throne's AI each classified the same 278 stool images across all seven Bristol types, and none of those images had been used to train the model.

The AI agreed with the physicians about as closely as the physicians agreed with one another. That covers the stool-form feature rather than every measurement the device reports, and it is not evidence that any device can diagnose a condition.

Why does that matter? If you are going to track something over months, it helps to know the underlying read has been checked against clinicians rather than against a reference chart. For a category this new, published evidence of any kind is rare.

The Bristol Stool Form Scale itself has a research base. A 2016 validation study found that stool-form classifications were associated with measured stool water content. That supports the scale as a way to describe stool form, not the accuracy of any particular device that uses it.

The number of categories also affects how much detail a device can show. Throne classifies stool using all seven Bristol types. Dekoda groups consistency into three categories: regular, hard, or loose. A shift between Bristol types may therefore appear in Throne’s record without changing Dekoda’s broader label. More categories provide more detail, but do not automatically make a reading more accurate.

In a hands-on review, Reviewed found Dekoda easy to install but described its insights as basic for the price and subscription requirement. The review also reported a false negative when testing a sample containing blood in a dark bathroom. This was a hands-on test, not a clinical study, so it cannot establish how often such errors occur.

What Does Throne Measure?

Throne records stool characteristics, hydration-related signals, urinary flow, and bathroom timing. Its app lets you review these measurements over time.

Sensing. A downward-facing camera uses computer vision to analyze stool. An acoustic sensor measures urinary flow during standing sessions.

Stool form and amount. Throne classifies stool using the seven-point Bristol Stool Scale and estimates volume and diameter. It also records frequency and timing, making it easier to review changes across multiple visits.

Hydration. Optical analysis of urine color estimates urine concentration and produces a Hydration Score, according to Throne’s science overview. The app also displays a timeline of urine color. Because urine color can be influenced by factors other than hydration, the score is best treated as a trend rather than a definitive measure of hydration status.

Urinary flow. An acoustic sensor estimates peak flow, average flow, and duration. This measurement works during standing sessions because the sensor listens to the stream entering the water.

Bathroom timing. Throne records time spent on the toilet, when a session finishes, and the interval before the first bowel movement.

What's useful about having all these measurements in one place is being able to look beyond a single bathroom visit. Maybe you're curious whether your hydration has changed, or whether your stool consistency has been different lately. Instead of trying to remember what happened last week, you can look back at your actual measurements and see how your patterns have changed.

These measurements offer a record of selected bathroom patterns. They do not explain why a change occurs or establish whether it reflects a medical problem.

How Does Throne Identify Users?

Throne can recognize a paired phone over Bluetooth and assign a session automatically. A button on the device provides a manual option when your phone is elsewhere.

Up to six people can maintain separate profiles in one household. Automatic identification depends on a paired phone being recognized, so households should consider how often members carry their phones into the bathroom.

What Does Kohler Dekoda Measure?

Dekoda uses optical sensors to analyze waste. Its app reports stool characteristics and estimates hydration status.

Stool form and amount. Dekoda sorts stool consistency into three categories and amount into minimal, moderate, or substantial.

Stool color. It assigns one of six labels: brown, black, green, pale, yellow, or red.

Possible blood. Dekoda offers an alert for the possible presence of blood in stool. An alert cannot determine the cause, and the absence of one does not rule out bleeding.

Hydration. The device estimates hydration status through urine analysis and displays the result in the Kohler Health app.

How Does Dekoda Identify Users?

Dekoda requires users to authenticate each session through fingerprint recognition on its remote or through the Kohler Health app. Up to six people can maintain separate profiles under its family membership.

The remote comes with a wall-mounting bracket, but it is still another device to keep within reach. Unlike Throne’s phone-based automatic identification, Dekoda adds a step before a visit can be associated with a user.

Which Device Is Easier to Use Every Day?

The main difference is whether you need to identify yourself before each visit.

Throne can record automatically. It recognizes a paired phone over Bluetooth, with a button available for manual recording.

Dekoda requires authentication first. You start each session with a fingerprint on the remote or a login in the app, and Kohler states that the device only works during authenticated visits.

Upkeep differs as well. Launch coverage puts Dekoda's battery at about a week unplugged against Throne's 30 days, which is roughly a weekly charge against a monthly one. Dekoda's battery is removable and charges over USB-C, and Kohler suggests leaving the device plugged in where an outlet is close by.

Sessions are bounded at both ends. A Kohler user manual for the device lists a minimum session of 30 seconds and a maximum of five minutes.

Think about how often you use the bathroom without giving it a second thought. With Dekoda, you'll need to remember to identify yourself each time you want a visit recorded. With Throne, a paired phone can take care of that automatically.

That might sound like a small difference, but when the whole point is tracking patterns over weeks and months, convenience matters. The less effort it takes to record a visit, the easier it is to build a consistent history.

What Does Each Device Cost?

Throne costs less upfront and has a lower listed monthly membership fee for one user.

Estimates use the listed monthly rates and include the device price. They assume three included months of Throne membership and nine paid months in the first year. Check current prices and terms before buying.

Here's where Throne's value becomes particularly compelling. At the listed rates, you'll pay about $80 less during your first year, despite getting automatic tracking, more detailed stool-form classification, and urinary-flow measurements. Throne also comes with a two-year warranty, compared with one year for Dekoda.

In other words, you don't have to pay more to get those additional tracking capabilities.

Households should compare membership plans separately. Throne’s membership includes the first three months for up to two people. Dekoda’s reported family plan costs $12.99 per month for up to six profiles. Depending on the number of users and the available plan terms, the family option may be less expensive for a larger household.

Both companies advertise HSA/FSA eligibility for eligible customers. Whether you can use those funds depends on your plan and the applicable rules. Annual membership options may also change the totals, so check the current terms before purchasing.
