My Toilet Knows My Blood Pressure: Invisible Wellness Comes Home

I have sold homes with wine cellars, golf simulators, and one memorable basement built as a faithful replica of an English pub, dartboard and sticky floor included.  So I assumed I had seen every amenity a buyer could possibly fall in love with. Then the industry handed me a new phrase: "invisible wellness." It sounds like something you would order at a juice bar in Winnetka, but it is the hottest feature in luxury real estate. 

I am old-fashioned in this respect. I still put a lot of weight in the visible Wellness features:. Parks and green spaces, fresh air inside and outside your home, decent water piped into your house, and good nearby schools. So what are these invisible things that make us more centered then?

The Numbers Are Not Invisible

Let’s consider the data courtesy of the Global Wellness Institute, which is, I am sure, a neutral observer funded only by philanthropy. In 2025, about 60% of homeowners said health and wellness features were the main reason they bought their home. That is a 17-point jump from just three years earlier. The global wellness real estate market reached roughly $876 billion last year after growing 23% in a single year, and it is projected to hit $1.8 trillion by 2030. Americans account for close to 29% of that spending, which will surprise nobody who has ever watched us shop for supplements.

So what exactly are people paying for?

What Invisible Wellness Looks Like (Or Doesn't)

The list reads like a spa brochure written by an engineer:

• Whole-house air and water filtration
• Quiet rooms and sensory spaces designed for decompression
• Built-in health monitoring
• Spa-style bathrooms
• Biophilic design

That last one is the fancy term for bringing nature indoors through light, views, natural materials, and greenery. House Beautiful has crowned it the design trend of 2026.

Here on the North Shore, we have been quietly practicing biophilic design for about a century. We just called it "a house on the ravine with big windows." The Prairie School architects who shaped so many homes in Wilmette, Glencoe, and Highland Park were blurring the line between indoors and out long before anyone gave it a hashtag. Frank Lloyd Wright was simply early to the trend, as geniuses tend to be.

The Gadget Aisle

If you are not building from scratch, there is a growing menu of wellness tech to choose from. Some of it is delightful, and some of it is frankly a little more intimate than I'd like.

• A ceiling fixture that mimics natural daylight to support your circadian rhythm, yours for about $6,900. I would argue anyone who has survived February in Glenview deserves one, ideally subsidized by the state.
• A $199 smart toilet seat that tracks your blood pressure, heart rate, and breathing. The company behind it raised $46 million to bring it to market. Note: Please don’t buy a house for a toilet seat!
• A lounge chair north of $9,500 with vibrating plates and light-therapy goggles to calm the nervous system. Tip: I use Sancerre in a reclining chair. Cost $30.
• A startup developing a diffuser that releases fragrances to soothe your brain into sleep. Is that not what a lavender oil infuser is for?

Wellness for the Rest of Us

The encouraging news is that wellness is not purely a luxury play. Developers are increasingly designing entire communities around green space, natural elements, and places where neighbors actually see each other. If you think about it, that is a pretty good description of a North Shore downtown on a summer evening. Our forest preserves, our lakefront, and the steady revival of our small downtowns are wellness amenities that no smart chair can replicate. And as I have written before, whole-house water filtration works best when you start with Lake Michigan.

What This Means If You're Buying or Selling

For sellers, if you have upgraded your HVAC with serious air filtration, installed a quality water system, or have mature landscaping and an abundance of natural light, those features matter more than ever. The challenge is that invisible wellness is, well, invisible. It does not photograph the way a waterfall island does, so the story has to be told deliberately in your marketing. That is where I come in.

For buyers, many of these features can be added to an older home with good bones. A lovely 1920s colonial with a modern filtration system and a quiet reading nook is wellness real estate, even if nobody has slapped the label on it yet.

And finally, my wine cellar qualifies as a sensory room. As my husband attests: It is quiet, temperature controlled, impervious to spousal efforts at communication from upper floors, and nobody has ever left it stressed.
