Smart Toilets: Would You Track Your Stools Like You Track Your Steps? (Bloomberg)

would you buy one?

Equipped with sensors and AI, smart toilets promise to monitor hydration, gut health and even cancer risk — if users can get past the ick factor.

“This is the dream,” declares Will Bulsiewicz. The gastroenterologist is gently cradling a dried piece of feces with his bare hands and chatting breezily on The Diary of a CEO podcast. Careful not to disturb its contours, he decides the specimen — resembling an oversize Snickers bar from a distance — ranks a Bristol 4.

“That’s real poop,” host Steven Bartlett interjects.

“It’s lovely,” Bulsiewicz replies, removing neither hand. “The Bristol 4,” he says, referring to the ideal score on the Bristol Stool Form Scale, the medical rubric for assessing fecal matter, “is the classic where I come out, walking out of the bathroom in slow motion, rock music is jamming, and doves are flying in slow motion, and I am such a stud.”

During their hourslong exchange, the pair bantered about bathroom habits — the average person poops 1.7 times a day — and geeked out over how short-chain fatty acids act as a lubricant for stool. While it’s not a typical Bartlett episode, such reverence for bowel movements, as though each were a freshly discovered Rodin, no longer feels fringe. Fascination with fecal data has moved well beyond the biohacker manosphere and Bryan Johnson acolytes.

This year industry giants Toto Ltd. and Kohler Co. introduced smart toilets capable of analyzing what lands in the bowl, joining a cluster of startups betting on the same idea. Their conviction: People are quite literally perched atop an untapped reservoir of data that could improve health outcomes and even save lives.

I have one of those fancy schmancy toilets and the joy of not flushing and a warm seat are real!

But having said that, the risk of every intervention needs to be discussed, and in this case, the risk is you might become a little feral and forgot to flush when using a regular toilet :slight_smile: Ask me how I know.

If I recall, one of the other women here was part of a testing group and used one that provided actual analysis…

Beth, the other woman was probably me: I tested the Casana toilet in my home and also participated in testing at their site. The toilet seat has sensors in it to measure pulse, blood oxygen saturation, and they were just getting ready to beta the blood pressure measuring. Very cool, but they have a lot of competition.

Which one? and how good are the biometrics? very actionable?

@Deborah_Hall Yes, thank you for clarifying. It was indeed you!

@RapAdmin I have the Toto Neorest that was shown in your first link, but alas, while it’s a fabulous toilet, it does not offer analytics
