The Ultimate Smart Toilet Review: Transforming Your Bathroom into a High-Tech Sanctuary in 2026
Introduction
The bathroom has long been the last frontier of home automation. While our living rooms, kitchens, and bedrooms have embraced smart technology, the humble toilet has remained largely analog—until now. In 2026, the smart toilet has evolved from a novelty into a legitimate home investment, offering features that blend hygiene, comfort, and connectivity in ways that would have seemed futuristic just a decade ago. From heated seats and bidet functions to voice-activated flushing and health monitoring, today’s smart toilets are redefining what it means to have a truly intelligent home. Whether you’re a tech enthusiast looking to complete your smart home ecosystem, someone with mobility concerns seeking greater independence, or simply a homeowner wanting to reduce toilet paper usage and improve sanitation, this review will guide you through the best options available. We’ve tested the top contenders to help you decide which smart toilet deserves a place in your home.
Top 3 Product Recommendations
1. Kohler Numi 2.0 Intelligent Toilet
Overview: The Kohler Numi 2.0 is the gold standard of smart toilets, and for good reason. This isn’t just a toilet; it’s a bathroom command center. With a sleek, modern design that resembles a piece of contemporary furniture, the Numi 2.0 integrates seamlessly into any high-end bathroom. It features a built-in bidet with adjustable water temperature, pressure, and position, a heated seat, a warm air dryer, and even a deodorizer. But what sets it apart is its voice-control capabilities, compatible with Amazon Alexa, Google Assistant, and Apple HomeKit. The Numi 2.0 also includes customizable user presets, a nightlight, and a remote control with a full-color touchscreen.
Performance: In our testing, the Numi 2.0 delivered an exceptional user experience. The bidet function is precise and comfortable, with multiple spray patterns including a gentle “feminine wash” and a more targeted “posterior wash.” The heated seat is a game-changer during winter months, and the warm air dryer is surprisingly effective—you may never need toilet paper again. The voice control works flawlessly, allowing you to flush, open the lid, and adjust settings hands-free. The self-cleaning feature uses UV light to sanitize the bowl after each use, which is a huge plus for hygiene.
Pros:
- Industry-leading build quality and design
- Comprehensive smart home integration (Alexa, Google, HomeKit)
- Exceptional bidet and drying performance
- User presets for multiple family members
- Self-cleaning UV sanitation
Cons:
- Extremely expensive ($7,000–$8,500)
- Requires professional installation
- Large footprint may not fit small bathrooms
Price: Approximately $7,500 (2026 estimate)
Verdict: If budget is no object and you want the absolute best, the Kohler Numi 2.0 is the smart toilet to beat. It’s a luxury item that delivers on every promise.
2. Toto Neorest NX2
Overview: Toto has been a pioneer in bidet technology for decades, and the Neorest NX2 represents the pinnacle of their engineering. This toilet combines Toto’s legendary Tornado Flush system with a high-end bidet seat that includes oscillating and pulsating wash modes, a heated seat, and a warm air dryer. The NX2 also features Toto’s eWater+ system, which uses electrolyzed water to clean the bowl and the wand, reducing the need for harsh chemicals. It’s compatible with Amazon Alexa and Google Assistant, though it lacks Apple HomeKit support.
Performance: The Neorest NX2 is a workhorse. The Tornado Flush is incredibly powerful yet quiet, using a cyclonic rim wash to clear the bowl completely with just one flush. The bidet experience is refined, with adjustable water temperature and pressure that feel precise and luxurious. The eWater+ system is a standout feature—it automatically cleans the bowl and the bidet wand after each use, ensuring maximum hygiene. The seat is ergonomically designed and heated, and the lid opens automatically when you approach. Voice control is responsive, though it requires a separate hub for full functionality.
Pros:
- Powerful, efficient flush system
- Excellent bidet with multiple wash modes
- eWater+ self-cleaning technology
- Automatic lid and seat operation
- Reliable Toto quality and durability
Cons:
- No Apple HomeKit support
- Voice control requires additional hub
- Expensive ($5,500–$6,500)
- Limited customization compared to Kohler
Price: Approximately $6,000 (2026 estimate)
Verdict: The Toto Neorest NX2 is a close second to the Kohler, offering superior flushing performance and self-cleaning technology at a slightly lower price. Ideal for those who prioritize reliability and hygiene.
3. Bio Bidet A7
Overview: For those who want smart toilet features without the luxury price tag, the Bio Bidet A7 is an excellent choice. This is a bidet seat attachment that can be added to most standard toilets, transforming them into smart toilets. It includes a heated seat, a warm water bidet with adjustable pressure and temperature, a warm air dryer, and a remote control. The A7 also features a deodorizer, a nightlight, and a slow-closing seat. It’s compatible with Amazon Alexa and Google Assistant for voice control.
Performance: The Bio Bidet A7 punches well above its weight. The bidet function is surprisingly powerful and adjustable, with a comfortable spray pattern. The heated seat warms up quickly, and the air dryer, while not as powerful as the Kohler or Toto, gets the job done. The remote control is intuitive, and the voice control integration works well for basic commands like flushing and seat heating. Installation is straightforward—it can be done in under an hour with basic tools. The A7 is also one of the most energy-efficient options, with an eco-mode that reduces power consumption.
Pros:
- Affordable entry point for smart toilet features

Buying Guide
Who Should Buy a Smart Toilet?
- Tech Enthusiasts: If you love automating every aspect of your home, a smart toilet is the ultimate addition. Voice control, user presets, and health monitoring features will appeal to early adopters.
- Elderly or Mobility-Impaired Users: Automatic lid opening, heated seats, and hands-free bidet functions make smart toilets ideal for those with limited mobility or arthritis.
- Eco-Conscious Homeowners: Smart toilets can significantly reduce toilet paper usage, saving money and reducing waste. Many models also use less water per flush than standard toilets.
- Families: User presets allow each family member to have their own comfort settings, while self-cleaning features reduce the need for constant scrubbing.
- Luxury Home Renovators: If you’re remodeling a master bathroom, a high-end smart toilet like the Kohler Numi 2.0 can be a stunning centerpiece.
Budget Considerations
- Under $500: The Bio Bidet A7 and similar seat attachments are your best bet. They offer most essential features without requiring a full toilet replacement.
- $1,000–$3,000: Mid-range integrated toilets from brands like American Standard and Woodbridge offer good features like heated seats and bidets, though they may lack advanced smart home integration.
- $4,000–$8,500: Premium models like the Kohler Numi 2.0 and Toto Neorest NX2 offer the best performance, design, and smart features. Expect professional installation and a longer warranty.
Installation Considerations
- DIY vs. Professional: Seat attachments like the Bio Bidet A7 can be installed in under an hour with basic tools. Integrated toilets require professional plumbing and electrical work, which can add $200–$500 to the total cost.
- Electrical Requirements: Most smart toilets need a nearby electrical outlet. If your bathroom lacks one, you may need to hire an electrician.
- Plumbing: Ensure your bathroom has the correct water supply line (usually 1/2-inch or 3/8-inch). Some models require a dedicated hot water line for the bidet.
Installation & Smart Home Integration
Installation Process
Installing a smart toilet can range from simple to complex depending on the model.
For Seat Attachments (e.g., Bio Bidet A7):
- Turn off the water supply and flush to empty the toilet tank.
- Remove the existing toilet seat.
- Attach the bidet seat to the toilet using the provided mounting brackets.
- Connect the T-valve to the water supply line and attach the bidet’s water hose.
- Plug the bidet into a nearby electrical outlet.
- Turn on the water supply and test for leaks.
For Integrated Toilets (e.g., Kohler Numi 2.0):
- Hire a licensed plumber to remove the old toilet and prepare the floor flange.
- Ensure a dedicated electrical outlet is within 3 feet of the toilet.
- Install the toilet according to the manufacturer’s instructions, which usually involves securing the base, connecting the water line, and plugging in the power cord.
- Set up the remote control and connect to your Wi-Fi network.
- Calibrate the sensors for automatic lid and seat operation.
Smart Home Integration
All three recommended models support voice control, but the level of integration varies:
- Kohler Numi 2.0: Works with Amazon Alexa, Google Assistant, and Apple HomeKit. You can create routines like “Good Night” to dim the nightlight and lower the seat.
- Toto Neorest NX2: Compatible with Alexa and Google, but requires a Toto Connect+ hub. No HomeKit support.
- Bio Bidet A7: Works with Alexa and Google via the Smart Life app. Basic commands like “flush” and “heat seat” are supported.
For a truly seamless experience, the Kohler Numi 2.0 is the best choice, especially if you’re an Apple user. However, even the Bio Bidet A7 adds a surprising amount of convenience for its price.
Conclusion & Final Verdict
The smart toilet market in 2026 offers something for every budget and lifestyle. The Kohler Numi 2.0 remains the undisputed king, offering unparalleled luxury, design, and smart home integration. It’s a statement piece that transforms your bathroom into a spa-like retreat, but its $7,500 price tag puts it out of reach for most homeowners.
The Toto Neorest NX2 is a worthy alternative, especially if you value flushing performance and self-cleaning technology. It’s slightly more affordable and backed by Toto’s legendary reliability, though it lacks Apple HomeKit support.
For the vast majority of buyers, the Bio Bidet A7 is our top recommendation. At just $450, it delivers the core smart toilet experience—heated seat, warm water bidet, and voice control—without requiring a full bathroom renovation. It’s easy to install, energy-efficient, and compatible with Alexa and Google. While it doesn’t have the premium feel of integrated models, it offers the best value for money.
Final Verdict: If you can afford it, buy the Kohler Numi 2.0. If you want the best performance-to-price ratio, go with the Toto Neorest NX2. But if you’re looking for a practical, affordable way to upgrade your bathroom, the Bio Bidet A7 is the smart choice.
