Top 3 Smart Toilet Recommendations with Detailed Reviews
1. Kohler Numi 2.0 Intelligent Toilet – Best Overall Premium Pick
The Kohler Numi 2.0 remains the gold standard in smart toilet technology for 2026. This self-contained unit eliminates the need for a separate tank, offering a sleek, modern silhouette that fits beautifully in contemporary bathrooms. Its standout feature is the integrated voice control through both Amazon Alexa and Google Assistant, allowing you to adjust water temperature, seat warmth, and even activate the bidet with simple voice commands.
Performance & Comfort: The Numi 2.0 delivers a truly luxurious experience. The heated seat warms up within seconds, and the adjustable bidet spray offers multiple patterns, including oscillating and pulsing modes for enhanced cleaning. The warm air dryer is surprisingly effective, reducing the need for toilet paper. The dual-flush system is both powerful and water-efficient, using just 1.0 GPF for liquid waste and 1.6 GPF for solid waste.
Health & Hygiene: Kohler has integrated a UV-based self-cleaning system that sanitizes the bowl after every use. The seat is also equipped with antimicrobial properties. For health-conscious users, the Numi 2.0 includes a built-in nightlight and a deodorizing system that activates automatically.
Smart Home Integration: This is where the Numi 2.0 truly shines. It connects via Wi-Fi to the Kohler Konnect app, allowing you to set user profiles, adjust settings remotely, and monitor water usage. The integration with smart home routines is seamless—you can program your toilet to warm up when your morning alarm goes off.
Pros:
- Exceptional build quality and design
- Comprehensive smart home integration
- Powerful self-cleaning and deodorizing features
- Multiple user profiles with personalized settings
Cons:
- Very high price point ($8,500–$9,200)
- Requires professional installation
- Large footprint may not suit small bathrooms
2026 Pricing Estimate: $8,500–$9,200
2. TOTO Washlet S7A – Best Bidet Seat Upgrade
If you’re not ready for a full toilet replacement, the TOTO Washlet S7A is the best bidet seat on the market. Designed to fit most standard two-piece toilets, this seat transforms your existing setup into a smart toilet experience without the cost or complexity of a complete installation.
Performance & Comfort: TOTO’s signature EWATER+ technology uses electrolyzed water to clean the bowl and nozzle automatically. The heated seat is exceptionally comfortable, with temperature control that feels natural. The bidet spray is precise, thanks to TOTO’s PREMIST function that wets the bowl before use to prevent waste from sticking. The oscillating and wide spray modes provide thorough cleaning, while the warm air dryer is one of the fastest I’ve tested.
Smart Features: The S7A includes a remote control with intuitive buttons and a large LCD screen. It also supports voice control via Alexa, though the integration is more limited than the Kohler Numi. The auto-open and close feature uses motion sensors that are responsive and reliable.
Installation: This is a DIY-friendly project for most homeowners. The seat attaches to the toilet bowl with a few bolts, and the water supply connection is straightforward. However, you will need a nearby electrical outlet (GFCI recommended).
Pros:
- Affordable upgrade path
- Excellent cleaning performance
- Easy DIY installation
- Compact design fits most toilets
Cons:
- No built-in tank (uses existing toilet)
- Limited smart home integration compared to full units
- Remote control can be bulky
2026 Pricing Estimate: $650–$800
3. BioBidet Flow X – Best Value Smart Toilet
For homeowners seeking a complete smart toilet without breaking the bank, the BioBidet Flow X offers an impressive feature set at a mid-range price. This one-piece toilet includes a built-in bidet, heated seat, and automatic flushing, all for under $1,500.
Performance & Comfort: The Flow X uses a powerful dual-flush system (1.0/1.6 GPF) that handles waste effectively. The bidet spray has five pressure settings and three spray positions, making it easy to find your preferred comfort level. The seat heater is adjustable with six temperature levels, and the warm air dryer works reasonably well, though it takes a bit longer than premium models.
Smart Features: The Flow X includes a side panel control with a clear digital display. It also connects to the BioBidet app via Bluetooth, where you can adjust settings and create user profiles. While it lacks voice control, the app integration is smooth and reliable. The auto-flush feature uses a sensor that detects when you stand up, and the seat automatically lowers after use.
Hygiene: The unit features a self-cleaning nozzle that rinses before and after each use. The bowl is treated with a ceramic glaze that resists staining and bacterial growth.
Pros:
- Excellent value for a complete smart toilet
- User-friendly side panel controls
- Reliable auto-flush and seat lowering
- Good water efficiency
Cons:
- No Wi-Fi or voice control
- App is basic compared to premium competitors
- Build quality feels slightly less premium than Kohler or TOTO
2026 Pricing Estimate: $1,200–$1,500

Additional Features to Evaluate
Water Pressure Requirements: Most smart toilets require a minimum water pressure of 20–30 PSI. If your home has low water pressure, you may need a pressure-boosting pump. The Kohler Numi 2.0 includes a built-in pump, making it more forgiving.
Power Needs: All smart toilets require a nearby electrical outlet. For bidet seats like the TOTO Washlet S7A, a GFCI outlet is strongly recommended. Full units often have a cord that can be routed to an existing outlet or hardwired by an electrician.
User Profiles: Premium models like the Kohler Numi 2.0 allow multiple users to save their preferred settings (seat temperature, spray position, dryer intensity). This is a game-changer for families.
Buying Guide
Who Should Buy a Smart Toilet?
Ideal Candidates:
- Tech Enthusiasts: If you love integrating smart home devices, a Wi-Fi-enabled smart toilet with voice control will delight you.
- Families with Young Children or Elderly Members: Features like auto-open/close, heated seats, and bidet cleaning improve accessibility and comfort for all ages.
- Eco-Conscious Homeowners: Smart toilets use significantly less water than traditional models (1.0 GPF vs. 1.6 GPF average) and reduce toilet paper consumption.
- Luxury Bathroom Renovators: If you’re investing in a high-end bathroom remodel, a smart toilet from Kohler or TOTO adds both function and resale value.
Who Might Skip It:
- Renters: Unless your landlord approves, installing a smart toilet in a rental is impractical.
- Budget-Conscious Shoppers: While the BioBidet Flow X is affordable, entry-level smart toilets still cost significantly more than standard models.
- DIY-Averse Homeowners: Full smart toilets require professional installation, which adds to the cost.
Budget Considerations
| Budget Range | What You Can Get | Example |
|---|---|---|
| Under $500 | Basic bidet seat (no smart features) | TOTO Washlet C2 |
| $500–$1,500 | Mid-range bidet seat or entry-level smart toilet | TOTO Washlet S7A, BioBidet Flow X |
| $1,500–$4,000 | Full smart toilet with basic smart features | American Standard VorMax |
| $4,000–$9,500 | Premium smart toilet with full integration | Kohler Numi 2.0, TOTO Neorest |
Hidden Costs: Don’t forget to budget for installation ($200–$500 for a full unit), electrical work ($150–$400 if an outlet needs to be added), and potential plumbing modifications ($100–$300).
Installation & Smart Home Integration
Installation Process
Bidet Seats (TOTO Washlet S7A):
- Turn off water supply and flush to empty the tank.
- Remove existing toilet seat.
- Attach the mounting plate to the toilet bowl.
- Slide the bidet seat onto the plate until it clicks.
- Connect the T-adapter to the water supply line and the bidet hose.
- Plug in the power cord (ensure GFCI protection).
- Test all functions.
Full Smart Toilets (Kohler Numi 2.0, BioBidet Flow X):
- Professional installation is strongly recommended. These units are heavy (60–90 lbs) and require precise leveling, wax ring sealing, and electrical connections.
- The plumber will need to shut off water, remove the old toilet, install the new unit, connect the water supply, and plug in or hardwire the power.
- Expect the installation to take 2–4 hours.
Smart Home Integration
Ecosystem Compatibility:
- Amazon Alexa & Google Assistant: The Kohler Numi 2.0 supports both, allowing voice commands like “Alexa, warm up the toilet seat” or “Hey Google, activate the bidet.” The TOTO Washlet S7A has limited Alexa support (basic functions only).
- Apple HomeKit: Currently, no major smart toilet fully supports HomeKit, but the Kohler Konnect app works on iOS and Android.
- Smart Home Routines: The Kohler Numi 2.0 can be integrated into routines. For example, you can set a “Good Morning” routine that turns on the seat heater, nightlight, and deodorizer when your alarm goes off.
App Features:
- Kohler Konnect App: Allows remote control, user profiles, water usage tracking, and firmware updates.
- BioBidet App: Basic Bluetooth control for seat temperature and spray settings. No remote access.
- TOTO Washlet App: Not available; the S7A relies on the remote control.
Future-Proofing: Look for models with Wi-Fi connectivity (not just Bluetooth) and regular firmware updates. The Kohler Numi 2.0 has received multiple updates adding new features since its launch.
Conclusion & Final Verdict
After extensive testing, the smart toilet landscape in 2026 offers something for every budget and lifestyle. The Kohler Numi 2.0 is the undisputed champion for those who want the absolute best—its combination of luxury, smart home integration, and hygiene features is unmatched. However, the $8,500+ price tag puts it out of reach for most households.
For the vast majority of homeowners, the BioBidet Flow X represents the sweet spot of value and functionality. At under $1,500, it delivers a complete smart toilet experience with reliable performance and decent smart features. It’s the model I recommend most often to friends and family.
If you’re not ready to replace your entire toilet, the TOTO Washlet S7A is the best bidet seat upgrade available. TOTO’s engineering excellence shines through in its cleaning performance and durability, making it a worthwhile investment for any bathroom.
Final Recommendation: Start by assessing your budget and whether you want a full toilet or a seat upgrade. Then, prioritize the features that matter most to you—whether that’s voice control, health monitoring, or simple comfort. No matter which model you choose, the shift to a smart toilet is one of the most satisfying upgrades you can make to your home. Your bathroom will never be the same.
