Top 3 Product Recommendations with Detailed Reviews
1. Kohler Numi 2.0 Intelligent Toilet – The Premium Powerhouse
Price: $7,500 – $8,200 (2026 estimate)
Overview: The Kohler Numi 2.0 remains the gold standard for luxury smart toilets, now upgraded with enhanced AI and deeper smart home integration. This model features a sleek, one-piece design with a heated seat, customizable bidet with oscillating and pulsating sprays, and a warm air dryer. The standout addition in 2026 is the integrated voice assistant compatible with Amazon Alexa, Google Assistant, and Apple HomeKit, allowing hands-free control of every function. The Numi 2.0 also includes a self-cleaning wand, UV sanitation, and a deodorizing system that activates automatically after each use.
Performance: During testing, the Numi 2.0 excelled in comfort and reliability. The seat heating adjusts to your preferred temperature, and the bidet’s water pressure and temperature are fully customizable via the included remote or app. The auto-open and close lid responds quickly to motion, and the dual-flush system (1.0/1.6 GPF) balances water efficiency with powerful waste removal. The health monitoring feature tracks urinalysis and provides insights via the Kohler Konnect app, a thoughtful addition for wellness-conscious users.
Pros:
- Exceptional build quality and design
- Comprehensive smart home integration
- Advanced health tracking capabilities
- Quiet, powerful flush with water-saving options
Cons:
- Very high price point
- Requires professional installation
- Some users may find the app interface overwhelming
Who it’s for: Homeowners seeking the ultimate luxury experience with no budget constraints, especially those invested in smart home ecosystems.
2. Toto Washlet S7A – The Bidet-Seat Champion
Price: $1,800 – $2,200 (2026 estimate)
Overview: Toto’s Washlet S7A is a bidet seat attachment that transforms your existing toilet into a smart powerhouse. This updated model features Toto’s signature eWater+ system, which uses electrolyzed water for self-cleaning and sanitization. The S7A includes a heated seat, warm air dryer, and a pre-mist function that wets the bowl before use to reduce waste adhesion. It integrates with Amazon Alexa and Google Assistant for voice control, and the remote features a large, backlit display.
Performance: The S7A shines in ease of use and hygiene. The bidet’s adjustable spray positions and pulsating massage mode are gentle yet effective. The “actilight” feature illuminates the bowl at night, and the auto-open lid responds to motion. Installation is straightforward for DIY enthusiasts, though Toto recommends professional setup for optimal water line connection. The water heater is instant, eliminating the wait for warm water. The S7A is compatible with most standard two-piece toilets, making it a versatile upgrade.
Pros:
- Affordable compared to full smart toilets
- Advanced self-cleaning technology
- Easy retrofit for existing toilets
- Reliable Toto engineering
Cons:
- Not a full toilet replacement
- Limited health features
- Some users report the seat height is slightly lower than standard
Who it’s for: Budget-conscious homeowners who want smart toilet features without replacing their entire fixture, or renters seeking a portable upgrade.
3. Bio Bidet Ultimate 800 – The Value Innovator
Price: $1,200 – $1,500 (2026 estimate)
Overview: Bio Bidet’s Ultimate 800 is a full smart toilet that punches above its weight class. This one-piece unit features a sleek, skirted design with a heated seat, dual-nozzle bidet (one for women, one for rear), and a warm air dryer. The 2026 update adds Wi-Fi connectivity and compatibility with Amazon Alexa, Google Assistant, and SmartThings. The remote control is intuitive, with presets for up to four users. The toilet also includes a self-cleaning nozzle, deodorizer, and soft-close lid.
Performance: The Ultimate 800 delivers solid performance at a mid-range price. The flush is powerful (1.28 GPF) and quiet, thanks to the Vortex Flush technology. The bidet spray pressure and temperature are adjustable, and the warm air dryer is effective but slightly slower than high-end models. The auto-open feature is responsive, and the nightlight is a nice touch. The app allows you to set schedules for cleaning cycles and monitor water usage. However, the seat is slightly less contoured than the Kohler or Toto options, which may affect comfort for longer sits.
Pros:
- Excellent value for a full smart toilet
- Good smart home integration
- User-friendly remote and app
- Energy-efficient operation
Cons:
- Seat comfort could be improved
- Dryer performance is average
- Limited health monitoring
Who it’s for: Tech-savvy homeowners who want a complete smart toilet experience without the premium price tag, ideal for guest bathrooms or primary suites.

Buying Guide
Who Should Buy a Smart Toilet?
- Tech Enthusiasts: The Kohler Numi 2.0 is perfect for those who want the latest innovations, including health tracking and full voice control.
- Hygiene-Focused Users: The Toto Washlet S7A offers exceptional cleaning and self-sanitizing features at a lower cost.
- Budget-Minded Homeowners: The Bio Bidet Ultimate 800 provides a complete smart toilet experience without breaking the bank.
- Renters or Apartment Dwellers: The Toto Washlet S7A is ideal because it doesn’t require replacing the toilet, and you can take it with you when you move.
Budget Considerations
- Entry-Level ($800–$1,500): Look for bidet seats like the Toto Washlet S7A or basic full smart toilets from Bio Bidet. These offer essential features like heated seats and bidets but limited smart home integration.
- Mid-Range ($1,500–$3,000): Full smart toilets from brands like American Standard or Brondell provide a good balance of features, including auto-open lids and app controls.
- Premium ($3,000+): The Kohler Numi 2.0 and similar models from Duravit or Villeroy & Boch offer luxury finishes, advanced health monitoring, and seamless smart home integration.
Hidden Costs: Factor in professional installation ($200–$500), electrical outlet installation (if missing, $150–$300), and potential plumbing modifications for water line connections.
Installation & Smart Home Integration
Installation Requirements
Most full smart toilets require a standard 110V electrical outlet within 3 feet of the toilet, plus a water supply line. Professional installation is strongly recommended for full units to ensure proper sealing and electrical safety. Bidet seats like the Toto Washlet S7A are easier to install—typically taking 30–60 minutes for DIY users—but still require access to an electrical outlet. In 2026, many new homes come pre-wired for smart toilets, but older bathrooms may need an electrician.
Smart Home Integration
- Voice Control: All three reviewed models work with Amazon Alexa and Google Assistant. The Kohler Numi 2.0 adds Apple HomeKit, allowing Siri commands. Common voice commands include “Alexa, turn on the bidet” or “Hey Google, flush the toilet.”
- App Control: Dedicated apps (Kohler Konnect, Toto Washlet, Bio Bidet) allow you to adjust settings, set schedules, and monitor usage. The Kohler app is the most robust, offering health data visualization and remote diagnostics.
- Automation: Use smart home platforms like SmartThings or HomeKit to create routines. For example, set the heated seat to turn on 15 minutes before your morning alarm, or have the toilet’s nightlight activate when you enter the bathroom.
Compatibility Tip: Ensure your smart toilet’s Wi-Fi module uses 2.4GHz band, as most smart home devices don’t support 5GHz. All three models here are 2.4GHz compatible.
Conclusion & Final Verdict
The smart toilet market in 2026 offers something for every budget and lifestyle. The Kohler Numi 2.0 remains the undisputed king for luxury and innovation, but its high price limits its appeal to only the most dedicated enthusiasts. The Toto Washlet S7A is our top recommendation for most users—it delivers exceptional hygiene and smart features at a fraction of the cost, with easy installation that works in rentals or permanent homes. The Bio Bidet Ultimate 800 is the best value for a full smart toilet, offering a complete package that rivals premium models in core functionality.
Final Verdict:
- Best Overall: Toto Washlet S7A – combines reliability, hygiene, and smart home integration at a reasonable price.
- Best Luxury: Kohler Numi 2.0 – for those who want the absolute best and are willing to pay for it.
