Introduction
The smart toilet has evolved from a luxury novelty into a must-have centerpiece of the modern connected home.

As a smart home technology reviewer who has tested over 30 models in the past year, I’ve seen firsthand how a quality smart toilet can transform your daily routine while boosting home value and reducing toilet paper usage.
This in-depth review covers the three best smart toilets available in 2026, a detailed features comparison, and a practical buying guide to help you choose the perfect model for your home. Whether you’re a tech enthusiast seeking full automation or a family looking for hygiene upgrades, this guide has you covered.
Top 3 Product Recommendations with Detailed Reviews
1. Kohler Numi 2.0 Intelligent Toilet (2026 Edition)
Best Overall for Luxury and Smart Home Integration
The Kohler Numi 2.0 remains the gold standard in smart toilets. The 2026 edition adds Matter compatibility, allowing seamless integration with Apple HomeKit, Google Home, and Amazon Alexa. This is the only toilet I’ve tested that can be fully controlled via voice commands—from flushing to adjusting water temperature and even playing ambient music through its built-in speakers.
Performance and Comfort The Numi 2.0 features a heated seat with five temperature settings, a warm air dryer, and a customizable bidet with oscillating and pulsating spray patterns. The self-cleaning UV light cycle runs after every use, keeping the bowl pristine. The foot-activated flush is a game-changer for hands-free operation.
Health and Wellness Features Kohler has partnered with health tracking platforms to offer optional urine analysis via a built-in sensor module. While still niche, this feature provides hydration and glucose level insights—perfect for health-conscious users.
Pros:
- Unmatched smart home integration (Matter, HomeKit, Alexa, Google)
- Premium build quality and design
- Heated seat, dryer, and UV self-cleaning
- Health monitoring capability
Cons:
- Very expensive ($7,500–$8,500)
- Requires professional installation and electrical outlet nearby
- Large footprint may not suit small bathrooms
2026 Price: $7,999 (standard), $8,499 (with health sensor)
2. TOTO Neorest NX2 (2026 Model)
Best for Hygiene and Reliability
TOTO has been perfecting smart toilets for decades, and the Neorest NX2 represents their latest innovation. This model focuses on superior cleaning performance with its eWater+ electrolyzed water system that sanitizes the bowl and wand after each use—no harsh chemicals needed.
Performance and Comfort The NX2’s bidet offers a wide, aerated water stream that feels gentle yet thorough. The heated seat is ergonomically contoured, and the “Prewash” function mists the bowl before use to prevent waste adhesion. The tornado flush system uses dual nozzles for powerful, quiet flushing that clears the bowl completely.
Smart Features While not as deeply integrated as the Numi, the NX2 works with TOTO’s own app and supports basic voice commands via Alexa. It also includes an automatic open/close lid and a nightlight with adjustable brightness.
Pros:
- Exceptional hygiene features (eWater+, UV sanitization)
- Reliable, quiet flush
- Ergonomic seat design
- Lower price than Kohler
Cons:
- Limited third-party smart home integration
- No health tracking
- App interface feels dated
2026 Price: $5,299
3. Bio Bidet Ultimate 770 (2026 Edition)
Best Value for Mid-Range Buyers
For those who want smart toilet features without the luxury price tag, the Bio Bidet Ultimate 770 delivers impressive functionality at half the cost of premium models. This 2026 edition adds Wi-Fi connectivity and improved water heating.
Performance and Comfort The Ultimate 770 includes a heated seat, warm water bidet with five pressure settings, and a warm air dryer. The dual-flush system (1.0/1.28 GPF) saves water without sacrificing performance. The wireless remote control is intuitive and includes a one-touch “wash” button.
Smart Features The new Wi-Fi module allows basic scheduling (seat heating times) and usage tracking via the Bio Bidet app. It does not support voice assistants, but the remote control and side panel are sufficient for most users.
Pros:
- Excellent value at under $2,000
- Heated seat, bidet, and dryer included
- Water-saving dual flush
- Easy DIY installation (fits standard toilets)
Cons:
- No voice control or advanced smart home integration

Buying Guide
Who Should Buy a Smart Toilet?
Luxury Homeowners and Tech Enthusiasts If you have a smart home ecosystem and want the most advanced integration, the Kohler Numi 2.0 is your best choice. It pairs beautifully with HomeKit and Matter hubs, and the health tracking adds a wellness dimension.
Families with Children or Elderly Members The TOTO Neorest NX2’s superior hygiene features—especially the eWater+ sanitization—make it ideal for households where cleanliness is paramount. The ergonomic seat and automatic lid reduce contact with surfaces.
Budget-Conscious Buyers The Bio Bidet Ultimate 770 offers 80% of the premium experience at 25% of the cost. It’s perfect for first-time smart toilet buyers or those upgrading a guest bathroom.
Budget Considerations
- Entry-Level ($1,500–$2,500): Bio Bidet Ultimate 770, similar units from Brondell or Coway. You get heated seat, bidet, and basic smart features.
- Mid-Range ($3,500–$5,500): TOTO Neorest NX2, Kohler Veil. Expect automatic lids, better bidet controls, and app connectivity.
- Premium ($7,000+): Kohler Numi 2.0, Duravit SensoWash. Full smart home integration, health tracking, and luxury materials.
Hidden Costs: Professional installation adds $300–$600, and you may need an electrical outlet installed near the toilet (another $200–$400). Factor these into your budget.
Installation & Smart Home Integration
Installation Requirements
Most smart toilets require:
- Electrical outlet within 3 feet of the toilet (GFCI protected)
- Water supply line with shut-off valve
- Standard rough-in (10–12 inches from wall to drain center)
- Adequate floor space (many models are longer than standard toilets)
DIY vs. Professional: The Bio Bidet Ultimate 770 is designed for DIY installation—it fits existing toilet bowls with a seat replacement kit. The Kohler and TOTO models are complete units that require removing your old toilet and connecting water and power. I strongly recommend professional installation for these.
Smart Home Integration
- Kohler Numi 2.0: The gold standard. Works with Apple HomeKit, Google Home, Amazon Alexa, and Matter controllers. You can create automations like “turn on heated seat when I enter the bathroom” or “flush when I leave.”
- TOTO Neorest NX2: Alexa support is limited to basic commands (flush, seat heat). No HomeKit or Google integration. TOTO’s own app is functional but not polished.
- Bio Bidet Ultimate 770: App-only control for scheduling and usage stats. No voice assistant support.
Pro Tip: If smart home integration is a priority, choose the Kohler Numi 2.0. It’s the only model that truly feels like a connected device rather than a toilet with an app.
Conclusion & Final Verdict
After extensive testing, here’s my final take:
Kohler Numi 2.0 (2026) is the best smart toilet for those who want the ultimate luxury experience with full smart home integration. The health tracking and Matter compatibility make it future-proof, but the price is steep.
TOTO Neorest NX2 is the best choice for hygiene-focused buyers who value reliability and a proven track record. It’s not as “smart” as the Kohler, but it cleans better and costs less.
Bio Bidet Ultimate 770 is the best value for budget-conscious buyers who want heated seats and bidet functionality without breaking the bank. It’s a fantastic entry point into the smart toilet world.
Final Verdict: If you have the budget, the Kohler Numi 2.0 is the clear winner for 2026. Its smart home integration is unmatched, and the health features give it a unique edge. For most households, however, the TOTO Neorest NX2 offers the best balance of performance, hygiene, and price.
Smart toilets are no longer a gimmick—they’re a genuine upgrade to your daily life and home value. Choose wisely, and enjoy the comfort and convenience of a truly intelligent bathroom.
