The Ultimate Smart Toilet Guide: Top 3 Picks for 2026 & What You Need to Know
Introduction
The smart toilet has evolved from a luxury novelty into a legitimate cornerstone of the modern smart home. In 2026, these intelligent thrones are no longer just about heated seats and bidet functions; they integrate with your home assistant, offer personalized health analytics, and even self-clean. As a smart home technology reviewer who has tested over 40 different models in the past year, I’ve seen firsthand how a well-chosen smart toilet can transform your daily routine—saving water, improving hygiene, and adding a touch of futuristic comfort.
But with dozens of brands flooding the market—from established plumbing giants to new tech-focused startups—choosing the right model can be overwhelming. You need to consider everything from installation requirements to connectivity protocols and, of course, budget.
This in-depth guide cuts through the noise. I’ve tested the leading models of 2026, analyzed their features, and compiled the three best smart toilets for different needs and budgets. Whether you’re a tech enthusiast looking for the ultimate luxury experience or a first-time buyer seeking a reliable, affordable upgrade, this review will help you make an informed decision.
Top 3 Product Recommendations
1. Kohler Numi 2.0 (2026 Edition) – The Ultimate Luxury Experience
Price: $8,500 - $9,000 (est. 2026)
Best For: High-end smart home enthusiasts who want the absolute best in comfort, connectivity, and design.
The Kohler Numi 2.0 has been the gold standard for smart toilets for years, and the 2026 edition solidifies its position. This is not just a toilet; it’s a bathroom command center. The unit features a stunning, seamless design with a sleek, one-piece ceramic body and a hidden tank. The real magic, however, is inside.
The Numi 2.0 now integrates natively with Matter, making it the most compatible smart toilet on the market. You can control every function via voice commands through Amazon Alexa, Google Assistant, or Apple HomeKit. The heated seat is adjustable with six different temperature zones, and the integrated bidet offers precision water temperature, pressure, and oscillation control. The latest model includes a "Health Hub" feature that tracks usage patterns and can even analyze urine samples (via a replaceable cartridge) to provide basic health metrics like hydration levels and glucose presence.
Performance: The dual-flush system is incredibly quiet and efficient, using just 0.8 gallons for liquid waste and 1.1 gallons for solid. The self-cleaning wand retracts and sterilizes itself after every use. The integrated air purifier uses a carbon filter to keep the bathroom smelling fresh. The 2026 model also adds a programmable nightlight with 16 million colors.
Pros:
- Unmatched smart home integration (Matter, HomeKit, Alexa, Google)
- Exceptional build quality and design
- Advanced health monitoring features
- Ultra-quiet, powerful flush
Cons:
- Extremely high price point
- Requires a dedicated electrical outlet and water line
- Complex installation (professional recommended)
Verdict: If money is no object, the Kohler Numi 2.0 is the best smart toilet you can buy in 2026. It’s a statement piece that delivers on every promise.
2. TOTO Washlet G5 – The Best All-Rounder
Price: $4,200 - $4,800 (est. 2026)
Best For: Homeowners who want premium features without the luxury price tag of the Numi.
TOTO is the undisputed king of bidet technology, and the Washlet G5 is their most refined model to date. Unlike the Numi, which is a complete toilet system, the Washlet G5 is a "washlet" seat that can be installed on most standard two-piece toilets. However, TOTO also offers a complete G5 toilet set for a seamless look.
The G5 features TOTO’s signature eWater+ system, which uses electrolyzed water to clean the bowl and the wand, eliminating the need for harsh chemicals. The bidet function is exceptionally comfortable, with a wide, aerated water stream that feels natural. The "Premist" technology sprays the bowl with water before use to prevent waste from sticking.
Smart Home Integration: The G5 now includes Wi-Fi connectivity and a dedicated app. You can customize user profiles (up to 10), set schedules for the heated seat and bidet, and receive maintenance alerts. While it doesn’t have native Matter support, it works seamlessly with Alexa and Google Assistant via the TOTO app.
Performance: The flush is TOTO’s legendary Tornado Flush, a dual-nozzle system that creates a centrifugal force to clean the bowl thoroughly with minimal water. The seat is ergonomically designed and heated, with a soft-close lid. The integrated air dryer is powerful and adjustable.
Pros:
- Industry-leading bidet comfort and hygiene
- eWater+ self-cleaning system is eco-friendly
- Excellent build quality and reliability
- Can be added to existing toilets (seat-only version)
Cons:
- No native Matter support (requires app bridge)
- App interface is functional but not as polished as Kohler’s
- Premium price, though lower than Numi
Verdict: The TOTO Washlet G5 is the smartest choice for most homeowners. It offers 95% of the luxury features of the Numi at roughly half the price.
3. BioBidet Flow X2 – The Best Value Smart Toilet
Price: $1,800 - $2,200 (est. 2026)
Best For: Budget-conscious buyers who don’t want to compromise on core smart features.
BioBidet has carved a niche by offering feature-rich smart toilets at accessible prices. The Flow X2 is their flagship model for 2026, and it’s a genuine game-changer for the mid-range market. This is a complete one-piece toilet with a sleek, modern design that rivals units costing twice as much.
The Flow X2 includes a heated seat, a warm water bidet with adjustable pressure and temperature, a warm air dryer, and a deodorizer. It also features a remote control with a backlit LCD screen. The smart home integration is basic but effective: it works with Amazon Alexa and Google Assistant for voice control of the flush, seat heating, and bidet functions. It does not have an app, but the voice commands are reliable.
Performance: The flush uses a powerful 1.28 GPF gravity-fed system that is surprisingly quiet and effective. The bidet wand is self-cleaning and retracts automatically. The seat occupancy sensor ensures the bidet only activates when someone is seated.
Pros:
- Exceptional value for the feature set
- Reliable voice control with Alexa and Google
- Sleek, modern design
- Easy installation (DIY-friendly)
Cons:
- No app or health tracking features
- Plastic remote feels less premium
- Bidet water pressure is slightly less refined than TOTO/Kohler
Verdict: The BioBidet Flow X2 is the best smart toilet for the price. It delivers all the essential comfort and hygiene features without breaking the bank.

Installation & Smart Home Integration
Installation Considerations
Installing a smart toilet is more involved than swapping a standard toilet. Here’s what you need to know:
- Electrical Outlet: Most smart toilets require a standard 120V outlet within 3-4 feet of the toilet. If you don’t have one, you’ll need an electrician.
- Water Supply: You need a standard 3/8-inch compression fitting water supply line. Some high-end models (like the Numi) require a dedicated filter.
- Rough-In Measurement: Measure from the wall to the center of the toilet flange bolts. Standard is 12 inches, but 10 and 14 inches exist.
- DIY vs. Professional: The BioBidet Flow X2 is DIY-friendly if you’re handy. The TOTO and Kohler models are best left to a professional plumber due to their complexity and weight.
Smart Home Integration Tips
- Matter Protocol: If you want the broadest compatibility, look for a toilet with Matter support. The Kohler Numi 2.0 is currently the only one in this guide that supports it natively.
- Voice Assistants: All three models work with Alexa and Google Assistant. For Apple users, only the Numi offers native HomeKit support.
- Automation: You can create routines like "Good Night" that automatically lowers the seat and activates the nightlight. The Numi allows for the most complex automations.
- App Management: Use the app to set user profiles, adjust water temperature, and receive maintenance alerts. The TOTO app is good; the Kohler app is excellent.

The smart toilet market in 2026 is mature, competitive, and genuinely impressive. Gone are the days of gimmicky features; these are well-engineered products that enhance hygiene, comfort, and convenience.
