Smart showers. Smart toilets. Smart toothbrushes. The bathroom is the new frontier for smart home marketing, and most of it is nonsense. A toothbrush that sends brushing data to your phone. A mirror that shows the weather while you shave. A toilet that tweets. (Yes, that’s real.) But buried under the gimmicks are a few genuinely useful upgrades that make your bathroom safer, more comfortable, and occasionally cheaper to run. Here are the ones worth your money.
The Useful Upgrades
1. Smart Leak Detectors Under the Sink and Toilet (20 to 30 Dollars Each)
Bathrooms are the second most common source of water damage in homes (after water heaters). A slow leak under the sink or behind the toilet can cause thousands of dollars in damage before you notice it. A Govee water sensor (20 dollars) or Aqara leak sensor (18 dollars) sits on the floor and sends your phone an alert the moment it detects moisture. Put one under each sink, one behind the toilet, and one near the bathtub. Total cost: under 80 dollars for full bathroom coverage. Compare that to the average 11,000-dollar water damage claim.

2. Smart Exhaust Fan with Humidity Sensor (80 to 150 Dollars)
A smart exhaust fan like the Delta Breeze Smart or a standard fan connected to a humidity-sensing smart switch turns on automatically when humidity rises above 60 percent and turns off when it drops. This prevents mold, protects your paint and drywall, and means you never forget to turn on the fan during a shower. The automation is the whole point — you don’t have to remember, and it runs exactly as long as needed.

3. Heated Towel Rack on a Smart Plug (50 to 100 Dollars)
A heated towel rack is a luxury that feels silly until you step out of the shower into a warm towel on a cold morning. Connected to a smart plug on a schedule (on at 6 AM, off at 8 AM, or triggered by your morning routine), it costs about 3 dollars per month in electricity and makes winter mornings significantly better. This is one of those upgrades that sounds ridiculous until you try it, and then you can’t go back.
4. Smart Lighting with Warm-to-Cool Tuning (25 to 40 Dollars)
Bathroom lighting matters more than you think. Bright, cool light (5000K) is great for makeup and shaving. Warm, dim light (2700K) is better for nighttime bathroom visits that don’t wake you up completely. Smart bulbs that adjust color temperature — like Wyze Color Bulbs or Philips Hue White Ambiance — let you set bright white for morning routines and dim warm for nighttime. Smart bulbs with color temperature tuning are the easiest bathroom lighting upgrade you can make.

5. Smart Thermostat with Remote Sensors (Already Have One? Add a Sensor)
If you already have an Ecobee thermostat, add a remote sensor to the bathroom. Bathrooms are often significantly warmer or cooler than the rest of the house, and your thermostat doesn’t know that. A remote sensor lets the system account for bathroom temperature when running your morning routine. See our thermostat ROI guide for more on why remote sensors matter.
6. Smart Plug for Hair Tools (15 Dollars)
The number one reason people call the fire department about home fires? Unattended cooking. Number two? Unattended hair tools. A smart plug on your curling iron or flat iron lets you set an auto-off timer (30 minutes, 1 hour) AND check from your phone whether you left it on. If you did, turn it off remotely. The Kasa smart plug (12 dollars) plus a 2-minute setup saves you from the “did I leave my straightener on?” panic that hits halfway to work.

7. Nightlight Motion Sensor (20 to 30 Dollars)
A motion-activated nightlight under the toilet or along the baseboard is one of those things you never think about until you have it. No turning on the overhead light at 2 AM. No stubbed toes. No bright light that makes it impossible to fall back asleep. The Aqara motion sensor plus a dim smart bulb or LED strip, set to turn on at 5 percent brightness during nighttime motion, is the ideal setup. Pair it with your nighttime routines for maximum effect.

8. Smart Mirror with Defogging (150 to 300 Dollars)
Not the kind that shows news headlines — that’s ridiculous. The useful feature is the built-in defogger. After a hot shower, you can see your face in the mirror immediately instead of wiping it with a towel. The defogging mirror options range from 150 dollars (basic LED mirror with defogger) to 300+ dollars (with Bluetooth speakers and color temperature adjustment). Skip the speakers. Get the defogger.

The Weird Stuff (Skip These)
Smart Toothbrushes
Oral-B and Philips Sonicare both make Bluetooth toothbrushes that track your brushing habits, show you missed spots on a map of your mouth, and send data to your dentist. Here’s the thing: if you brush for 2 minutes, twice a day, with proper technique, you’re doing fine. The app doesn’t make you a better brusher — it makes you someone who looks at a brushing map on their phone. Save the 100-dollar premium and buy regular replacement heads.
Smart Showers
The Moen Smart Shower (800 dollars) lets you start your shower from your phone, set the temperature to the degree, and save preset profiles for each family member. The U by Moen controller works with Alexa and Google Home. It’s cool tech. It’s also 800 dollars for something a 2-dollar shower handle already does. If you have a specific need (mobility issues, precise temperature requirements for medical reasons), it’s worth considering. Otherwise, turn the handle.
Smart Toilets
Bidet seats with heated water, air dry, and self-cleaning functions are genuinely nice (the TOTO Washlet is the gold standard). But “smart” toilets that connect to WiFi, track your bathroom visits in an app, and offer “health analytics” are a privacy nightmare waiting to happen. Your bathroom habits do not need a cloud connection.

The bathroom is where practical smart home upgrades really shine. Leak detectors save you from catastrophic water damage. Smart exhaust fans prevent mold automatically. A heated towel rack on a schedule makes winter mornings better. And a smart plug on your hair tools gives you peace of mind. The total cost for all eight useful upgrades is under 400 dollars — less than one “smart” shower system. Skip the connected toothbrush, skip the WiFi toilet, and focus on safety and comfort.

My take: Skip the tweeting toilets — what matters in a bathroom is $20 leak sensors, a fan that runs itself, and a smart plug that kills the curling iron you forgot. Those three prevent the real disasters; the heated towel rack is the luxury you’ll actually use daily.

Frequently Asked Questions
What bathroom smart upgrades are worth the money?
The unglamorous ones: leak sensors under sinks, behind the toilet, and near the tub ($18–20 each — bathrooms are the second most common water damage source after water heaters, against an average $11,000 claim; full coverage under $80), a smart exhaust fan or humidity-sensing switch that runs itself above 60% humidity, and a smart plug on hair tools with an auto-off timer — unattended hair tools are the #2 reason people call the fire department about home fires.
Are smart mirrors worth it?
Only the defogging kind — a built-in defogger ($150–300) means you can actually see after a hot shower instead of towel-wiping. Skip the headline-news mirrors (the post’s word: ridiculous). The better lighting spend: tunable white bulbs (Wyze or Hue White Ambiance, $25–40) — bright 5000K for makeup and shaving mornings, dim warm 2700K for night visits that don’t wake you fully.
What’s the most underrated bathroom smart upgrade?
The motion-activated nightlight — an Aqara sensor plus a dim bulb or LED strip at 5% brightness on nighttime motion: no overhead light at 2 AM, no stubbed toes, no wide-awake aftermath. Pair it with a heated towel rack on a smart plug ($50–100, ~$3/month on a morning schedule) for the version that feels like an affordable luxury.
