Top 3 Product Recommendations
1. Kohler Numi 2.0 Intelligent Toilet
Overview: The Kohler Numi 2.0 remains the gold standard for luxury smart toilets. Priced at approximately $8,500 in 2026, it combines premium materials with advanced technology. The unit features a sleek, skirted design with a vitreous china bowl and a heated seat with adjustable temperature settings. Its standout feature is the integrated voice control, compatible with Amazon Alexa, Google Assistant, and Apple HomeKit, allowing hands-free operation for flushing, seat warming, and bidet adjustments.
Performance: The Numi 2.0 excels in user experience. The dual-flush system (1.0/1.28 GPF) is both powerful and water-efficient, while the oscillating and pulsating bidet spray offers customizable pressure and temperature. The integrated air dryer and warm air deodorizer eliminate the need for toilet paper, promoting eco-friendliness. Health monitoring is a key upgrade: the toilet can analyze urine and stool samples via a built-in sensor, providing data on hydration levels and potential health markers through the KOHLER Konnect app. This feature is particularly appealing for health-conscious users.
Pros:
- Exceptional build quality and design
- Comprehensive health tracking
- Seamless smart home integration (Alexa, Google, HomeKit)
- Self-cleaning wand and UV sanitation
Cons:
- Very high price point
- Requires professional installation
- Health data privacy concerns for some users
Who It’s For: The Kohler Numi 2.0 is ideal for homeowners who prioritize luxury, health monitoring, and full smart home integration. It suits tech-savvy individuals with a budget exceeding $7,000 and a willingness to invest in a premium bathroom experience.
2. TOTO Washlet S7A (with Universal Toilet)
Overview: TOTO’s Washlet S7A, paired with a compatible toilet bowl, offers a more accessible entry into high-end smart toilets without sacrificing performance. The complete system (Washlet + bowl) costs around $3,200 in 2026. The S7A features TOTO’s signature eWater+ system, which uses electrolyzed water to clean the wand and bowl, reducing bacteria buildup. The seat is ergonomically designed with a soft-close lid and a heated surface.
Performance: The Washlet S7A delivers a powerful yet gentle bidet experience with its PREMIST technology, which pre-mists the bowl to prevent waste adhesion. The dual-action nozzle offers front and rear cleaning with adjustable water pressure and temperature. The unit includes a wireless remote control and a wall-mounted panel, making it easy to operate. Smart home integration is limited to basic voice commands via Alexa or Google Assistant for flushing and seat heating, but it lacks the advanced health tracking of the Numi. The toilet’s Tornado Flush system (1.28 GPF) is exceptionally quiet and efficient.
Pros:
- Excellent value for features offered
- Superior hygiene with eWater+ and PREMIST
- Quiet, powerful flush
- Easy to install as a retrofit or complete system
Cons:
- Limited smart home features compared to Kohler
- No built-in health monitoring
- Remote can be bulky
Who It’s For: The TOTO Washlet S7A is perfect for homeowners seeking a reliable, hygienic smart toilet with essential smart features at a mid-range price. It’s an excellent upgrade for families or individuals who want comfort and cleanliness without the premium price tag.
3. BioBidet Flow 7000
Overview: BioBidet’s Flow 7000 is a budget-friendly contender that doesn’t skimp on core features. Priced at approximately $1,800 for the complete toilet and bidet seat in 2026, it offers a compelling mix of functionality and affordability. The unit features a sleek, one-piece design with a heated seat, warm air dryer, and a self-cleaning wand. Its smart home integration is through a dedicated app that works with Alexa and Google Assistant for basic controls.
Performance: The Flow 7000 provides a solid bidet experience with adjustable water temperature, pressure, and nozzle position. The dual-flush system (1.0/1.28 GPF) is water-saving, and the included deodorizer effectively neutralizes odors. The app allows users to set user profiles, adjust settings, and monitor water usage. However, health monitoring is absent, and the voice control is limited to flushing and seat heating. The installation is relatively straightforward, with detailed instructions and a quick-connect water supply.
Pros:
- Affordable price point
- Good app integration with user profiles
- Effective odor control
- Easy DIY installation
Cons:
- Build quality feels less premium than Kohler or TOTO
- No health tracking features
- Limited voice control functionality

Buying Guide
Who Should Buy?

- Families: The TOTO Washlet S7A is ideal for households with multiple users, thanks to its reliable performance, easy-to-clean features, and mid-range price. The user profiles in the BioBidet app also work well for families on a budget.
- Budget-Conscious Buyers: The BioBidet Flow 7000 offers a solid entry point. It’s perfect for those who want smart toilet benefits without overspending.
- Eco-Conscious Users: All three models are WaterSense certified, but the TOTO’s eWater+ system and Kohler’s dual-flush efficiency make them top picks for reducing water and paper waste.
Budget Considerations
- Under $2,000: The BioBidet Flow 7000 is your best bet. It covers all essential smart features without breaking the bank.
- $2,000–$4,000: The TOTO Washlet S7A provides a significant upgrade in build quality and hygiene technology. This is the sweet spot for most homeowners.
- Above $7,000: The Kohler Numi 2.0 is for those who demand the absolute best. Consider this an investment in luxury and health monitoring.
Don’t forget to factor in installation costs ($200–$500 for professional setup) and potential electrical outlet installation ($150–$300) if your bathroom lacks one near the toilet.
Installation & Smart Home Integration
Installation Process
- Professional Installation: Recommended for the Kohler Numi 2.0 due to its complex electrical and plumbing requirements. The unit requires a dedicated 120V outlet and a water line with a shut-off valve. TOTO’s complete system also benefits from professional setup, though the Washlet seat can be retrofitted to an existing bowl.
- DIY Installation: The BioBidet Flow 7000 is designed for DIY enthusiasts. It includes a T-connector for the water supply and a simple bracket system for the seat. Most users can complete installation in under an hour with basic tools.
- Universal Considerations: Ensure your bathroom has a GFCI outlet within 3 feet of the toilet. If not, hire an electrician. Also, measure the rough-in distance (typically 10–12 inches) to ensure compatibility.
Smart Home Integration
- Voice Assistants: All three models support Alexa and Google Assistant, but the Kohler Numi 2.0 offers the deepest integration, including voice commands for all bidet functions, seat temperature, and even the deodorizer. The TOTO and BioBidet are limited to flushing and seat heating.
- Automation: The Kohler Numi 2.0 can be integrated into smart home routines (e.g., “Good morning” triggers a flush and preheats the seat). The BioBidet app allows basic scheduling for seat heating. TOTO’s app is more utilitarian, focusing on settings adjustments.
- Health Data: Only the Kohler Numi 2.0 offers health monitoring, syncing data to the KOHLER Konnect app. This can be shared with healthcare providers, but privacy-conscious users should review data policies carefully.
Conclusion & Final Verdict
The smart toilet market in 2026 offers something for every budget and lifestyle. The Kohler Numi 2.0 stands as the undisputed champion for luxury and health tracking, but its $8,500 price tag limits its appeal to a niche audience. The TOTO Washlet S7A strikes the best balance between performance, hygiene, and cost, making it our top recommendation for most households. Its eWater+ system and Tornado Flush deliver exceptional cleanliness and efficiency. For budget-minded buyers, the BioBidet Flow 7000 provides a reliable, feature-rich experience at a fraction of the cost.
Final Verdict:
- Best Overall: TOTO Washlet S7A – $3,200
- Best Premium: Kohler Numi 2.0 – $8,500
- Best Budget: BioBidet Flow 7000 – $1,800
Ultimately, the right smart toilet depends on your priorities: health monitoring, smart home integration, or pure value. Whichever you choose, you’re investing in a cleaner, more comfortable, and more efficient bathroom experience. As smart home technology continues to advance, the toilet is no longer just a fixture—it’s a connected hub for wellness and convenience.
