Top 3 Smart Toilet Recommendations for 2026
1. Kohler Numi 2.0 Intelligent Toilet
Price: $8,950 (estimated retail, 2026) Best for: Tech enthusiasts and luxury homeowners seeking ultimate smart home integration.
The Kohler Numi 2.0 remains the gold standard for smart toilets in 2026. This isn't just a toilet; it's a bathroom command center. The Numi 2.0 features a sleek, one-piece design with a built-in touchscreen remote, voice control via Amazon Alexa or Google Assistant, and even a Bluetooth speaker system. The heated seat offers customizable temperature zones, while the bidet provides adjustable water pressure, temperature, and oscillating spray patterns.
What sets the Numi 2.0 apart is its health tracking capability. The toilet can measure urine flow rate, body weight, and even analyze waste color (with optional add-ons). Data syncs to the Kohler Konnect app, giving you insights into your wellness over time. The self-cleaning bowl uses UV light and electrolyzed water to kill bacteria, and the lid opens automatically as you approach.
Pros:
- Unmatched smart home integration (Alexa, Google, Apple HomeKit)
- Advanced health monitoring features
- Heated seat with memory settings for multiple users
- Self-cleaning with UV sterilization
Cons:
- Extremely high price point
- Requires professional installation and dedicated electrical outlet
- Bluetooth speaker quality is adequate but not audiophile-grade
Verdict: If money is no object and you want the most feature-rich smart toilet available, the Numi 2.0 is the clear winner. It's a statement piece that redefines bathroom luxury.
2. Toto Neorest AC (with EWATER+)
Price: $7,500 (estimated retail, 2026) Best for: Those prioritizing hygiene, reliability, and elegant design.
Toto has been perfecting smart toilets for decades, and the Neorest AC represents the pinnacle of their engineering. This model features Toto's signature Tornado Flush, which uses dual nozzles to create a powerful, quiet, and water-efficient flush. The EWATER+ system electrolyzes tap water to create a natural cleaning agent that sanitizes the bowl before and after each use.
The Neorest AC includes a heated seat with graduated temperature control, a warm air dryer with adjustable speed, and a deodorizing system that activates automatically. The bidet wand is self-cleaning and offers three spray modes: posterior, feminine, and soft. The lid opens and closes automatically, and the toilet has a nightlight for late-night visits.
Pros:
- Exceptional flush performance with Tornado Flush technology
- EWATER+ system reduces need for harsh chemicals
- Comfortable, ergonomic seat design
- Reliable and backed by Toto's excellent warranty
Cons:
- Limited smart home integration (no Alexa/Google support)
- Health tracking features are basic compared to Kohler
- Installation requires a 120V outlet near the toilet
Verdict: The Neorest AC is the best choice for hygiene-focused buyers who want a proven, low-maintenance smart toilet. It's less flashy than the Numi but delivers where it matters most.
3. Bio Bidet Ultimate 770 (BB-770)
Price: $1,200 (estimated retail, 2026) Best for: Budget-conscious homeowners wanting smart features without breaking the bank.
The Bio Bidet Ultimate 770 is a smart bidet seat that transforms your existing toilet into a high-tech experience. It's not a full toilet replacement, but for under $1,500, you get heated seat, adjustable bidet with warm water, air dryer, and deodorizer. The wireless remote control mounts on the wall and offers intuitive controls for water pressure, temperature, and nozzle position.
This model includes a pre-mist function that wets the bowl before use to reduce waste sticking, and a self-cleaning nozzle with UV sterilization. The seat has a soft-close lid and a nightlight. While it lacks health tracking and voice control, the BB-770 delivers core smart toilet features at a fraction of the cost.
Pros:
- Affordable entry point into smart toilet technology
- Easy DIY installation on most standard toilets
- Heated seat and warm water bidet are very comfortable
- Reliable performance with good water pressure
Cons:

Additional Features to Evaluate

- Installation Complexity: Full toilets require a 120V outlet and water line access. Bidet seats are simpler.
Buying Guide: Who Should Buy Which Smart Toilet?
For the Tech Enthusiast (Kohler Numi 2.0)
If you own a smart home with multiple voice assistants and love having data on your health, the Numi 2.0 is your match. It's ideal for homeowners who view the bathroom as a sanctuary and are willing to invest heavily in the experience. The health tracking feature is particularly valuable for those monitoring chronic conditions like diabetes or kidney issues. However, be prepared for the high upfront cost and potential maintenance expenses.
For the Hygiene Purist (Toto Neorest AC)
The Neorest AC is perfect for families or individuals who prioritize cleanliness above all else. The EWATER+ system virtually eliminates the need for chemical cleaners, and the Tornado Flush ensures nothing is left behind. This model is also quieter than most, making it suitable for shared bathrooms where noise is a concern. It's a long-term investment that should last 15-20 years with proper care.
For the Budget-Conscious Buyer (Bio Bidet BB-770)
Renters, apartment dwellers, or anyone not ready to replace their entire toilet should choose the BB-770. It's also a great option for guest bathrooms or vacation homes where you want smart features without the commitment. The installation is straightforward—most people can do it in under an hour with basic tools. The trade-off is no smart home integration, but the core comfort features are excellent.
Budget Considerations
| Budget Range | Best Options |
|---|---|
| Under $2,000 | Bidet seats like Bio Bidet BB-770 or Toto S550e |
| $2,000 - $5,000 | Mid-range full toilets (e.g., Kohler Veil, American Standard VorMax) |
| $5,000 - $10,000 | Premium full toilets (Kohler Numi, Toto Neorest) |
Remember that installation costs can add $200-$500 for full toilets, especially if you need to run a new electrical outlet or water line.
Installation & Smart Home Integration
Installation Requirements
- Electrical: Most full smart toilets require a dedicated 120V, 15-amp outlet within 3 feet of the toilet. If you don't have one, hire a licensed electrician. Bidet seats often plug into existing outlets near the sink, but check cord length.
- Plumbing: Smart toilets use standard 12-inch rough-in measurements. Ensure your existing plumbing matches. The water supply line may need a filter for bidet models.
- Space: Measure your bathroom carefully. Smart toilets are typically larger than standard models. Allow at least 15 inches from the center of the toilet to any side wall.
Smart Home Integration
- Kohler Numi 2.0: Works with Amazon Alexa, Google Assistant, and Apple HomeKit. You can say "Alexa, flush the toilet" or set routines like "Goodnight" to lower the seat and activate the nightlight. The Kohler Konnect app allows remote control and health data access.
- Toto Neorest AC: No native voice control, but you can use a smart plug to turn the toilet on/off. Toto's app is limited to basic settings. For full integration, consider a third-party hub like Hubitat.
- Bio Bidet BB-770: No smart features at all. It's a standalone device with a wireless remote. For some, this simplicity is a plus.
Pro Tip: If smart home integration is critical, stick with Kohler or look for models with Matter certification (coming in late 2026 for some brands).
Conclusion & Final Verdict
Smart toilets in 2026 offer an impressive blend of comfort, hygiene, and technology. The Kohler Numi 2.0 leads the pack for those who want everything—voice control, health tracking, and luxury design. It's a splurge, but one that transforms your daily routine. The Toto Neorest AC is the reliable workhorse, perfect for families who value cleanliness and quiet operation. And the Bio Bidet Ultimate 770 proves you don't need to spend a fortune to enjoy heated seats and a bidet.
Final Recommendations
