The easiest way to make a bathroom smarter is usually a smart bidet toilet seat: it upgrades a fixture you already use, while a smart shower control or connected mirror can turn into a larger installation project. A scale and a toilet-rim sensor add connected tracking, but their data and privacy trade-offs deserve a closer look. These five categories range from practical upgrades to more ambitious systems; features vary by model, and the product claims below come from their manufacturers.
1. Smart bidet toilet seat: the clearest upgrade
A smart bidet toilet seat adds washing functions to an existing toilet, making it the most direct option for building a smarter bathroom without replacing the whole fixture. KOHLER lists PureWash E930, E750, E820, E700, E590, E545 and E525 bidet-seat models. Its smart-toilet lineup describes functions including front and rear wash, heated seats, warm-air drying and automatic cleaning on selected models; those features are not universal across the lineup. See KOHLER’s bidet-seat range and smart-toilet lineup for the specific models and functions.

Before choosing a seat, confirm that its shape and mounting fit your toilet, and check the electrical requirements for the exact model. Consider whether the household will use the wash, heating and drying features often enough to justify the added installation and cleaning. A feature list is not a compatibility guarantee.
2. Smart shower controls: a more integrated project
Digital shower controls can offer more precise control and customization, according to KOHLER. They are better treated as part of a shower installation or renovation than as a simple plug-in accessory: plumbing, electrical and control requirements depend on the system and the bathroom. KOHLER’s digital showering information describes the category, but does not establish universal compatibility or installation cost.

Check requirements for your existing shower and the specific control system before planning around a feature set. If you are not already changing the shower, weigh the extra installation work against the controls your household would actually use.
3. Smart scale: useful records, not a diagnosis
A Bluetooth scale can store body-composition records in an app and distinguish household users. Huawei’s regional product page describes Bluetooth 4.1 and recognition for up to 10 users; that is a manufacturer specification, not a study result. The page is for Nigeria, so verify the exact model’s availability in your location. Huawei’s Scale 3 page also says use is not recommended for people with pacemakers or other electronic medical implants.

- DESIGNED FOR ELONGATED TOILETS: Made for standard elongated toilet bowls, the SB-2000 includes a soft-close lid and seat, skin sensor, energy saving mode, and a 3 year warranty. DIY installation requires a 120V GFCI outlet; measure before ordering.
Body-composition figures from a consumer scale should not be treated as a diagnosis or as an independently validated health measure. If a reading could affect a medical decision, discuss it with a qualified clinician rather than relying on the app.
4. Connected mirror: an aspirational bathroom hub
CareOS describes a smart mirror as a way to access connected bathroom information and services, with health, beauty and IoT ecosystem brands among the integrations it names. The idea can be appealing if you want a bathroom interface for connected services, but it is less straightforward than adding a standalone scale or bidet seat: the value depends on the platform, compatible services and how you use them. See CareOS’s product information.
Rank #3
- Dual User Memory: Saves custom settings (seat heat, water temp, nozzle, pressure, dryer) for two users. One-touch remote recall ensures instant personalized comfort for every family member without manual readjustment

- 4-Level Custom Comfort: Fully adjustable heated seat, instant warm water, warm air dryer, and water pressure (4 settings each). Instant heating delivers consistent warmth without waiting, year-round
CareOS also uses AI mental-wellness language in its product description. Treat that as the company’s claim, not evidence of a proven clinical outcome. Before buying a connected mirror, check what information it collects, how connected services work, and whether the platform’s functions are available where you live.
5. Toilet-rim sensor: emerging tracking with privacy trade-offs
Throne Science says Throne One clips onto a toilet rim without tools or plumbing and uses computer vision and acoustic analysis to provide trends in its app. The company says a membership unlocks insights and describes its privacy practices. The product page listed $399 when accessed in 2026; that is a changeable vendor-listed price, not a market average. Review the current Throne Science product and service information before deciding.

A toilet sensor gathers information from a highly private setting. Read the vendor’s privacy terms closely, including what the device records, how data is stored or shared, and what remains available without a membership. The sensor’s trends are vendor-provided app information, not a substitute for clinical assessment.
How to choose the right smart bathroom setup
Start with the job you want the technology to do, then check the practical constraints before buying. These factors help distinguish a manageable accessory upgrade from a broader bathroom project:
Best Value
- Auto Open/Close: With the integration of advanced radar and body-sensing chip technology, this intelligent bidet seat offers a seamless automated experience.

- Revolutionary Comfort & Sleek Design: Boasting a patented appearance and innovative design, this bidet seat features a 32% slimmer profile and a 20% larger seat area, greatly enhancing comfort and providing a sitting experience as relaxing as lounging on a sofa.
- Instant Warm Water and Adjustable Comfort: Enjoy the luxury of instant and endless warm water, paired with the convenience of a 3-level, enhancing toilet bidet with adjustable warm air drying. Customize your experience with adjustable water temperature and pressure settings for a gentle and smooth clean. The warm air drying system ensures you feel fresh and dry, delivering a soft and soothing wash that offers exceptional comfort and hygiene.
- Thorough and Sanitary Cleaning: Featuring a self-cleaning, full ABS Plastic nozzle, this bidet ensures meticulous hygiene with a thorough cleaning experience. It promises optimum and thorough cleanliness, upholding the highest standards of hygiene for a refreshing and confident feeling after each use.
- Simple Operation and Fast Installation: Specifically designed for elongated bidets, easily manage the smart toilet seat using both a side knob and a wireless remote. Enjoy a quick 3-minute installation with a simple process that fits perfectly with your toilet. Product Dimensions: 19.9 x 14.75 x 3.65 inches | Weight: 9 lbs. If the T-valve size doesn't seem quite right during installation, don't hesitate to reach out to our customer support team for a 3/8” T-valve replacement.
- Compatibility: Check toilet shape and electrical supply for a bidet seat, and existing plumbing and system requirements for shower controls. Confirm phone and app support for connected products.
- Useful functions: Choose features your household will use, rather than treating a longer feature list as inherently better.
- Installation: A standalone scale or clip-on sensor has a different setup burden from a digital shower system. Verify what the exact product requires.
- Privacy and data: Check sensor use, account requirements, data controls and sharing before connecting health-related or bathroom-use information to an app.
- Ongoing costs: Find out whether core features require a membership or other recurring service fee.
- Cleaning and upkeep: Consider how each device affects routine bathroom cleaning and what maintenance its manufacturer specifies.
Accessibility still matters more than connectivity
A useful bathroom accessory does not have to be electronic. For people who benefit from seated showering, a shower stool can address an immediate accessibility need without adding an app or sensor. Etac says its Smart stool supports seated showering, offers multiple seating orientations and optional variants, and comes with a 5-year warranty and 10-year service life. Those are Etac’s stated product terms, not independently measured durability claims. See Etac’s Smart product page.
