Top 3 Smart Toilet Recommendations for 2026
After extensive testing across multiple price points and feature sets, these three models represent the best of what the smart toilet market has to offer in 2026.
1. TOTO Neorest NX2 (Premium Pick)
Price: $6,800 - $7,500
The TOTO Neorest NX2 remains the gold standard in luxury smart toilets, and for good reason. TOTO has been perfecting their washlet technology for decades, and the NX2 represents the pinnacle of their engineering expertise.
Performance and Features
The NX2's signature feature is its "Tornado Flush" system, which uses dual-nozzle technology to create a powerful swirling flush that thoroughly cleans the bowl with remarkably little water. During my testing, the flush was consistently effective—even with challenging waste—while remaining surprisingly quiet thanks to the insulated tank design.
The bidet functionality is where the NX2 truly shines. The wand extends and retracts with smooth precision, offering multiple spray patterns including posterior, soft, and front wash options. The oscillating and pulsating massage modes provide adjustable pressure control that ranges from a gentle mist to a focused stream. The water temperature is maintained precisely at your preferred setting, and the warm air dryer is genuinely effective, not just a token feature.
Smart Features
The NX2 includes an automatic lid that opens and closes via motion sensors, a heated seat with temperature control, and a deodorizing system that actually neutralizes odors using activated carbon and catalytic oxidation. The unit also features a pre-mist function that wets the bowl before use to prevent waste adhesion.
Comfort and Design
The ergonomic seat design is exceptional, with a slight contoured shape that reduces pressure during extended sitting. The slow-close lid operates silently, and the overall build quality is evident in every component, from the glazed ceramic to the soft-touch controls.
Pros:
- Exceptional build quality and reliability
- Superior flush performance with minimal water usage
- Advanced bidet features with precise controls
- Excellent odor neutralization system
- Quiet operation
Cons:
- Very high price point
- Professional installation required
- Limited color options (primarily white)
Verdict: The NX2 is the ultimate smart toilet for those who demand the absolute best. It's an investment, but one that offers years of reliable, comfortable service and significantly enhances daily bathroom experiences.
2. Kohler Numi 2.0 (Best for Smart Home Integration)
Price: $4,900 - $5,600
The Kohler Numi 2.0 isn't just a smart toilet; it's a statement piece that pushes the boundaries of what a bathroom fixture can be. Released in its current form in late 2024, the Numi 2.0 has matured into a polished product that integrates deeply with modern smart home ecosystems.
Performance and Features
The Numi 2.0 features Kohler's "Revolution 360" flush technology, which creates a powerful vortex that scours the entire bowl surface during every flush. The system uses a pressure-assisted flush mechanism that's both powerful and water-efficient, using just 1.1 gallons per flush.
The bidet system is comprehensive, offering rear and front wash modes with adjustable water pressure, temperature, and position. The wand is self-cleaning and features an ultraviolet light sanitation cycle that eliminates up to 99.9% of bacteria on the nozzle.
Smart Home Integration
This is where the Numi 2.0 truly distinguishes itself. It's compatible with both Amazon Alexa and Google Home, allowing voice control of nearly every function. You can say "Alexa, turn on the seat warmer" or "Hey Google, play music" directly from the toilet's integrated Bluetooth speaker. The speaker quality is surprisingly good, with clear audio that works well for podcasts or music while you're in the bathroom.
The Kohler Konnect app provides comprehensive control and monitoring. You can set schedules for the seat warmer, track water usage, and even receive maintenance alerts. The Numi 2.0 also supports IFTTT, enabling creative automation scenarios like triggering a bathroom fan when the toilet is occupied.
Ambient Features
The Numi 2.0 includes customizable ambient lighting with 16.8 million color options and dynamic lighting effects that can be set to respond to motion or sound. The "night light" mode is genuinely practical, providing just enough illumination to navigate the bathroom without fully waking you up.
Pros:
- Outstanding smart home integration
- Excellent voice control capabilities
- Built-in speaker system

- Powerful flush performance
Cons:
- Expensive
- Speaker quality isn't audiophile-grade
- App setup can be complex
- Requires strong Wi-Fi signal
Verdict: For tech enthusiasts who want their bathroom to be as connected as their living room, the Numi 2.0 is the obvious choice. Its voice control and automation capabilities are unmatched in the current market.
3. Bio Bidet Ultimate 8000 (Best Value for Features)
Price: $1,300 - $1,700
The Bio Bidet Ultimate 8000 proves that you don't need to spend five figures to get a genuinely excellent smart toilet experience. This model consistently outperforms its price point and offers features that compete with toilets costing three times as much.
Performance and Features
The Ultimate 8000 uses a standard gravity-fed flush system that's reliable if not particularly innovative. The real value lies in its bidet and comfort features. The bidet wand offers five spray modes—posterior, feminine, pulse, oscillating, and a "child mode" that provides a gentler spray for kids or sensitive users.
Water temperature is controlled via an instant water heater that maintains consistent temperature even during extended use. The warm air dryer has three temperature settings and includes a "turbo" mode that's genuinely effective at drying.
Comfort Features
The heated seat is a standout feature, with five temperature levels and a "eco" mode that reduces energy consumption when the seat is unoccupied. The toilet includes a remote control with a backlit LCD screen that's intuitive to use, even in low-light conditions.
The automatic lid opens and closes when you approach or leave, and the unit includes a "night light" that's soft and unobtrusive. The deodorizing system uses a carbon filter that's replaceable, and the bowl features a self-cleaning pre-mist function.
Smart Features
While not as deeply integrated as the Kohler Numi, the Ultimate 8000 does offer Bluetooth connectivity through the Bio Bidet app. The app allows for remote control of settings and provides usage statistics. It's not the most sophisticated app interface, but it's functional and adds value.
Pros:
- Exceptional value for the feature set
- Multiple bidet spray modes
- Consistent water temperature
- Intuitive remote control
- Energy-efficient eco mode
Cons:
- Flush system is basic
- Limited color options
- App features are somewhat basic
- Not as refined as premium models
Verdict: The Bio Bidet Ultimate 8000 is the sweet spot for most buyers. It delivers 90% of the premium smart toilet experience at less than a third of the price, making it our top recommendation for value-conscious consumers.

Water Efficiency and Flush Power
Modern smart toilets are designed to be water-efficient, with most models using between 1.0 and 1.6 gallons per flush (GPF). Look for toilets with EPA WaterSense certification, which ensures they use no more than 1.28 GPF while meeting performance standards.
However, water efficiency shouldn't come at the expense of flush power. The best smart toilets use engineering innovations like TOTO's Tornado Flush or Kohler's Revolution 360 to maximize cleaning effectiveness while minimizing water usage. When testing, pay attention to whether the flush leaves residue or requires multiple flushes—this is a common issue with budget models.
Bidet Functionality and Water Temperature Control
The bidet is the heart of the smart toilet experience. Key factors to evaluate include:
- Spray patterns: Basic models offer posterior and front wash only. Premium models add oscillating, pulsating, and massage modes that can be more comfortable and effective.
- Water temperature: Instant water heaters are superior to tank heaters because they provide consistent temperature regardless of usage duration. Tank heaters can run out of hot water during extended sessions.
- Adjustability: Look for controls that allow you to adjust water pressure, temperature, and nozzle position. The best models allow you to save custom profiles for different users.
Seat Comfort and Heating
Seat comfort is often overlooked but crucial for daily satisfaction. Consider:
- Seat shape and contour: Ergonomic designs that reduce pressure points make a significant difference during extended sitting.
- Heating levels: Multiple temperature settings allow you to find your ideal comfort level. Some models feature gradient heating that's warmer at the front and cooler at the back.
- Slow-close functionality: This prevents loud slamming and is a quality-of-life feature that's worth looking for.
Drying and Deodorizing Systems
A good warm air dryer should be effective enough to reduce or eliminate the need for toilet paper. Look for dryers with multiple heat settings and adjustable airflow direction.
Odor control is another important consideration. Basic carbon filters work adequately but require regular replacement. More advanced systems use catalytic oxidation or ozone technology to neutralize odors at the molecular level, which is more effective and requires less maintenance.
Smart Features and Connectivity
Smart toilet connectivity varies widely between manufacturers:
- App control: Most smart toilets offer basic app control, allowing you to adjust settings and monitor usage.
- Voice assistant integration: Premium models support Amazon Alexa and Google Home for hands-free control.
- Automation: Advanced models support IFTTT, enabling integration with other smart home devices.
- Health monitoring: Some luxury models can analyze urine for health metrics, though this feature is still in its infancy and not yet widely trusted.
Buying Guide: Who Should Buy What
First-Time Smart Toilet Buyers
If you're new to smart toilets, I recommend starting with a mid-range model like the Bio Bidet Ultimate 8000. This gives you the core smart toilet experience—heated seat, bidet, dryer, and basic connectivity—without a massive investment. You'll be able to determine which features you actually use and value before potentially upgrading to a premium model.
Tech Enthusiasts and Smart Home Power Users
For those with established smart home ecosystems, the Kohler Numi 2.0 is the clear winner. Its deep integration with Alexa, Google Home, and IFTTT allows for sophisticated automation scenarios that other toilets simply can't match. The ambient lighting and speaker features also add a "wow factor" that tech enthusiasts will appreciate.
Luxury Seekers and Design-Conscious Buyers
If you want the absolute best in terms of engineering, reliability, and comfort, the TOTO Neorest NX2 is unmatched. TOTO's decades of research into washlet technology result in a product that feels refined in every way. The build quality is exceptional, and the user experience is flawless.
Budget-Conscious Consumers
Smart toilet seats—which convert your existing toilet into a smart toilet—are an excellent budget option. Models like the TOTO Washlet C5 ($400-500) or the Bio Bidet BB-2000 ($350-450) offer good bidet functionality, heated seats, and warm air dryers for significantly less than full smart toilet units. The trade-off is that you won't get the integrated design or automatic lid features.
Elderly Individuals and Those with Mobility Issues
Smart toilets can be life-changing for those with limited mobility. The automatic lid, bidet functionality, and warm air dryer eliminate the need for twisting and turning. Look for models with remote controls that are easy to use and consider toilets with higher seat heights for easier transitions.
Budget Considerations for 2026
- Entry-level smart toilet seats: $300 - $600
- Budget smart toilets: $600 - $1,200
- Mid-range smart toilets: $1,200 - $2,500
- Premium smart toilets: $2,500 - $5,000
- Luxury smart toilets: $5,000 - $10,000+
Remember to factor in installation costs, which can range from $200 for basic installation to $1,000+ for complex setups that require electrical work or plumbing modifications.
Installation & Smart Home Integration
Professional vs. DIY Installation
Professional Installation (Recommended)
Smart toilets require both a water supply connection and a nearby electrical outlet. While some models can be installed as DIY projects, I strongly recommend professional installation for most buyers. Here's why:
- Electrical safety: Smart toilets draw significant power, especially when heating water. Proper grounding and GFCI protection are essential for safety.
- Plumbing considerations: Some smart toilets require specific water pressure levels or supply line sizes. A professional can ensure your plumbing meets requirements.
- Warranty protection: Many manufacturers require professional installation to maintain the warranty.
- Complexity: Modern smart toilets have multiple connections, including water supply, drain, and electrical. Getting these right the first time prevents leaks and electrical issues.
Installation Cost Estimates (2026)
- Basic installation (replacing existing toilet): $150 - $300
- Installation with electrical work: $300 - $600
- Complex installation (new bathroom or extensive modifications): $600 - $1,200
Smart Home Integration Strategies
Wi-Fi Requirements
Smart toilets require a stable Wi-Fi connection for app control and voice assistant integration. Position your router or use a mesh Wi-Fi system to ensure strong coverage in your bathroom. Some users find it helpful to install a dedicated access point for reliable connectivity.
Voice Assistant Setup
For Alexa integration, you'll typically need to enable the manufacturer's skill in the Alexa app and link your account. Google Home integration follows a similar process through the Google Home app. Once configured, you can control your toilet with voice commands like "Alexa, pre-heat the toilet seat."
Automation Scenarios
Here are some practical automation ideas for smart toilet integration:
- Motion-based lighting: Set your toilet's night light to activate when you enter the bathroom at night, triggered by a motion sensor.
- Schedule-based heating: Program the seat warmer to activate 15 minutes before you typically wake up.
- Occupancy-based ventilation: Connect your bathroom fan to turn on when the toilet detects occupancy and turn off 10 minutes after you leave.
- Usage statistics: Track water usage and set alerts for unusual patterns that might indicate a leak.
Troubleshooting Common Issues
- Wi-Fi connectivity problems: Try repositioning your router, using a Wi-Fi extender, or switching to a 2.4 GHz network (many smart devices don't support 5 GHz).
- App connection failures: Ensure your toilet's firmware is up to date and restart your phone before troubleshooting.
- Voice assistant issues: Re-link your smart toilet account in the voice assistant app and ensure you're using the correct device names.
