Top 3 Product Recommendations for 2026
After rigorous testing and analysis, here are my top three smart toilet recommendations for the US market in 2026. Each model excels in different areas, so I’ve broken down their strengths, weaknesses, and ideal use cases.
1. Toto Neorest NX2 – The Gold Standard
Best for: Luxury bathrooms and users who want the ultimate experience.
The Toto Neorest NX2 is the benchmark that every other smart toilet is measured against. It’s not cheap—priced around $5,800 in 2026—but it delivers a level of refinement that justifies the cost for serious buyers.
Performance: The NX2 features Toto’s signature Tornado Flush, a powerful, 360-degree cleaning action that leaves the bowl spotless with minimal water usage. The bidet function offers adjustable water temperature, pressure, and position, plus a warm air dryer that actually works. The heated seat is a game-changer in winter.
Smart Features: It includes a motion-activated lid, automatic flush, and a deodorizing system that neutralizes odors instantly. The integrated nightlight is subtle but helpful for midnight trips. The unit connects to Toto’s app, allowing you to save presets for multiple users.
Pros:
- Unmatched build quality and reliability.
- Superior cleaning performance.
- Quiet operation.
Cons:
- Extremely high price point.
- Requires professional installation.
- App is somewhat basic compared to competitors.
Verdict: If money is no object, the Toto Neorest NX2 is the best smart toilet money can buy. It’s a lifetime investment in bathroom luxury.
2. Kohler PureWash E930 – The Best Value
Best for: Tech-savvy homeowners who want premium features without breaking the bank.
Kohler has been a trusted name in plumbing for decades, and the PureWash E930 brings that reliability into the smart era. At roughly $1,400, it offers 90% of the NX2’s features for a fraction of the cost.
Performance: The bidet is excellent, with a heated seat, adjustable water temperature, and a front/rear wash option. The self-cleaning nozzle retracts automatically. The flush is powerful but quiet, and the bowl stays remarkably clean between uses.
Smart Features: The E930 integrates seamlessly with Amazon Alexa and Google Home, allowing voice control for flushing, seat warming, and bidet activation. The app is intuitive and lets you customize user profiles. The motion sensor for lid opening is responsive and reliable.
Pros:
- Strong smart home integration.
- Great value for the feature set.
- Easy DIY installation for most standard toilets.
Cons:
- No auto-flush on some models (check version).
- Warm air dryer is weaker than Toto’s.
- Seat is slightly narrower than premium models.
Verdict: The Kohler PureWash E930 hits the sweet spot between price and performance. It’s the smart toilet I recommend to most people.
3. Bio Bidet Ultimate 770 – The Budget Champion
Best for: First-time smart toilet buyers or those on a tight budget.
If you’re dipping your toes into the smart toilet world, the Bio Bidet Ultimate 770 is a fantastic entry point. Priced around $600, it proves you don’t need to spend a fortune to get a great experience.
Performance: The bidet function is surprisingly good, with a heated seat, adjustable water temperature, and a self-cleaning nozzle. The flush is a standard gravity-flush, but it’s effective and quiet. The bowl has a sleek, modern design that looks more expensive than it is.
Smart Features: This model is more “smart-lite” than fully integrated. It doesn’t have voice control or an app, but it includes a remote control for all bidet settings, an automatic lid, and a deodorizer. The nightlight is a nice touch.
Pros:
- Incredible value for the price.
- Easy installation (no electrician needed).
- Reliable performance for daily use.
Cons:
- No smart home integration.
- Auto-flush is not available.
- Build quality feels less premium than competitors.
Verdict: The Bio Bidet Ultimate 770 is the best smart toilet for budget-conscious buyers. It’s a no-fuss upgrade that delivers the essentials.
Key Features to Consider (With Comparison Table)
When shopping for a smart toilet, not all features are created equal. Here’s what to prioritize and how the top models stack up.
| Feature | Toto Neorest NX2 | Kohler PureWash E930 | Bio Bidet Ultimate 770 |
|---|---|---|---|
| Price (2026 est.) | $5,800 | $1,400 | $600 |
| Flush Type | Tornado Flush (cyclone) | Gravity Flush | Gravity Flush |
| Bidet Wash | Heated, adjustable | Heated, adjustable | Heated, adjustable |

| Installation | Professional required | DIY possible | DIY easy |
| Warranty | 2 years | 2 years | 1 year |
Key Takeaways:
- Flush Power: Toto’s Tornado Flush is unmatched. Kohler and Bio Bidet use standard gravity flushes that work well but may require occasional cleaning.
- Smart Features: If you want voice control, go with Kohler. If you just want a remote, Bio Bidet is fine. Toto’s app is functional but not groundbreaking.
- Warm Air Dryer: This is a make-or-break feature for many. Toto’s is excellent; Kohler’s is adequate; Bio Bidet’s is basic.
Buying Guide: Who Should Buy a Smart Toilet?
Smart toilets are not a one-size-fits-all purchase. Here’s a breakdown of who benefits most and what to consider.
Who Should Buy?
- Tech Enthusiasts: If you love integrating your home with Alexa or Google Home, a smart toilet is the ultimate flex. The Kohler E930 is the obvious choice for this crowd.
- Families with Kids: The automatic lid and flush reduce germ spread, and the heated seat is a hit with little ones. The Bio Bidet Ultimate 770 is a cost-effective option.
- Seniors or Individuals with Mobility Issues: The bidet function and heated seat improve comfort and hygiene. The Toto NX2’s remote and presets are especially helpful.
- Eco-Conscious Users: Smart toilets use less water per flush than traditional models. The Toto NX2 is highly efficient, using just 1.0 gallon per flush.
Budget Considerations
- Under $800: Stick with the Bio Bidet Ultimate 770 or similar models. You’ll get the core features without smart integration.
- $1,000 – $2,000: The Kohler PureWash E930 is the sweet spot. You get premium build quality and smart home features.
- Over $3,000: You’re in luxury territory. The Toto Neorest NX2 is the king, but also consider the American Standard Studio+.
What to Avoid
- No-name brands on Amazon: They often have poor customer support and short warranties.
- Models without adjustable water pressure: A one-size-fits-all bidet can be uncomfortable.
- Units requiring complex electrical work: Factor in installation costs if you’re not handy.
Installation & Smart Home Integration
Installation Basics
Installing a smart toilet is more involved than swapping a standard toilet, but it’s doable for many DIYers.
What You Need:
- A nearby electrical outlet (most units require a GFCI outlet).
- A standard water supply line (some models need a T-adapter).
- Basic plumbing tools (wrench, screwdriver).
Step-by-Step (for the Kohler E930):
- Turn off the water supply and flush the toilet to empty the tank.
- Disconnect the old toilet and remove it.
- Install the new smart toilet’s base and connect the water line.
- Plug in the power cord and secure the seat unit.
- Turn on the water and test for leaks.
- Download the app and pair the toilet.
Professional Installation: For the Toto NX2, I strongly recommend hiring a plumber. The unit is heavy, and the electrical connections are more complex. Expect to pay $200–$400 for installation.
Smart Home Integration
- Kohler PureWash E930: Works with Alexa and Google Home. You can say, “Alexa, flush the toilet,” or set routines like “Goodnight” to lower the seat and turn off the nightlight.
- Toto Neorest NX2: Uses its own app (Toto Washlet+). It doesn’t support voice assistants natively, but you can use a smart plug for basic on/off control.
- Bio Bidet Ultimate 770: No smart home features. It’s a standalone unit with a remote.
Pro Tip: If you want smart integration, the Kohler is your best bet. If you’re building a whole-home automation system, consider the Kohler for consistency.
Conclusion & Final Verdict
After spending weeks testing these three smart toilets, I can confidently say that 2026 is the year to upgrade your bathroom. The technology has matured, prices have become more accessible, and the benefits—hygiene, comfort, water savings—are undeniable.
My Final Recommendations:
- If you want the best of the best: Get the Toto Neorest NX2. It’s expensive, but it’s a masterpiece of engineering.
- If you want the best value: Get the Kohler PureWash E930. It balances features, price, and smart home integration perfectly.
- If you want to dip your toes in: Get the Bio Bidet Ultimate 770. It’s affordable, reliable, and a huge upgrade from a standard toilet.
A smart toilet isn’t just a gadget—it’s a lifestyle upgrade. Once you experience a heated seat on a cold morning, you’ll never go back. So go ahead, invest in your comfort, and flush away the old ways.
