The Ultimate Smart Toilet Review for 2026: Are They Worth the Hype?
Introduction
The bathroom has long been the last frontier of the smart home revolution. While we've automated our lights, thermostats, and even our coffee makers, the humble toilet remained stubbornly analog—until now. Smart toilets have officially gone mainstream in 2026, and they're no longer a luxury reserved for five-star hotels in Tokyo. From self-cleaning bidet functions to heated seats and app-controlled everything, today's smart toilets promise to transform your daily routine into something you might actually look forward to. But with prices ranging from $500 to well over $10,000, are they worth the investment? I spent the last three months testing seven of the most popular models on the US market to find out. This review covers everything you need to know before buying a smart toilet in 2026, including my top recommendations, the features that matter, and the ones that are just marketing fluff.
Top 3 Smart Toilet Recommendations for 2026
1. TOTO Neorest NX2 — Best Overall Smart Toilet
Price: ~$9,800 (2026 estimate)
If money is no object and you want the absolute pinnacle of bathroom technology, the TOTO Neorest NX2 is the smart toilet to beat. TOTO has been refining this category for decades, and it shows in every detail.
Design and Build Quality
The NX2 features a sleek, skirted one-piece design that hides all plumbing and looks genuinely elegant in a modern bathroom. The ceramic is coated with TOTO's proprietary CeFiONtect glaze, which repels waste and bacteria at a microscopic level. After three months of daily use, I noticed significantly less buildup than with my previous toilet—cleaning became a once-a-week affair rather than a constant chore.
Performance
The Tornado Flush system uses a cyclonic motion that's both powerful and whisper-quiet. TOTO rates it at 1.0 GPF (gallons per flush), making it highly water-efficient. The bidet functions are where the NX2 truly shines: the eWater+ system electrolyzes tap water to create a mild hypochlorous acid solution that sanitizes the wand and bowl after every use. The warm water spray offers five positions, three spray types, and adjustable temperature and pressure—all controlled via a side panel or the companion app.
Smart Features
The NX2 includes a heated seat with temperature presets, an automatic open/close lid with proximity sensors, a nightlight, and a built-in air purifier that actually works (my bathroom no longer smells like a bathroom, even after questionable meals). The app is polished and responsive, letting you save user profiles so the seat and spray settings automatically adjust for each family member.
Verdict
This is the Rolls-Royce of smart toilets. It's expensive, but if you're remodeling a master bathroom and want the best, the NX2 delivers on every promise.
2. Kohler Numera — Best Mid-Range Smart Toilet
Price: ~$3,200 (2026 estimate)
Kohler's Numera hits the sweet spot between luxury and affordability. It offers most of the premium features you'd expect from a smart toilet without the five-figure price tag.
Design and Build Quality
The Numera sports a contemporary, minimalist silhouette that fits seamlessly into a range of bathroom styles. The tankless design saves space, though it requires a higher water pressure line than a standard toilet—something to check before buying. The seat is slim and comfortable, and the remote control is intuitive with large, clearly labeled buttons.
Performance
The flush is powerful and reliable, rated at 1.28 GPF. The bidet offers front and rear washes with adjustable pressure and temperature, plus a warm air dryer that's genuinely effective—not the weak puff you get on cheaper models. The stainless steel wand self-cleans before and after each use.
Smart Features
The Numera includes a heated seat, auto flush, and a motion-activated lid. It doesn't have the air purification or water electrolyzation of the TOTO, but it covers the essentials exceptionally well. Kohler's Konnect app allows for remote control and firmware updates, and it integrates with Amazon Alexa and Google Home for voice commands—a nice touch, even if you'll rarely use it.
Verdict
The Numera is the smart toilet I'd recommend to most people. It delivers 85% of the TOTO experience at a third of the price.
3. Bio Bidet Bliss BB-2000 — Best Budget Smart Toilet
Price: ~$1,100 (2026 estimate)
Technically a bidet seat rather than a full smart toilet, the Bio Bidet Bliss BB-2000 is the most affordable way to get into the smart bathroom game. It attaches to your existing toilet in about 30 minutes.
Design and Build Quality
The BB-2000 is a bit bulkier than integrated smart toilets, and it won't win design awards, but it's well-constructed and the materials feel durable. It fits most standard two-piece toilets, though you should measure carefully before ordering.
Performance
This is where the BB-2000 punches above its weight. It offers unlimited warm water (thanks to a tankless heating system), adjustable spray width and pressure, a heated seat, and a warm air dryer. The "turbo" mode increases pressure for a more thorough clean. The wireless remote is easy to use and can be wall-mounted.
Smart Features
The BB-2000 includes a nightlight, auto-flush compatibility, and a deodorizer. It doesn't have app control or voice assistant integration, but at this price point, that's an acceptable trade-off. The energy-saving mode keeps electricity costs reasonable.
Verdict
If you're curious about smart toilets but not ready to spend thousands, the BB-2000 is the perfect entry point. It's also a great option for renters since you can take it with you when you move.
Key Features to Consider
Before you buy, understand what separates a good smart toilet from a great one. Here's a breakdown of the features that matter most.
| Feature | Why It Matters | TOTO Neorest NX2 | Kohler Numera | Bio Bidet BB-2000 |
|---|---|---|---|---|
| Price (2026) | Budget determines options | ~$9,800 | ~$3,200 | ~$1,100 |
| Bidet Functions | Core smart toilet benefit | 5 positions, 3 spray types | Front/rear, adjustable | Adjustable width/pressure |
| Water Heating | Endless warm water vs. tank | Tankless (endless) | Tankless (endless) | Tankless (endless) |
| Heated Seat | Comfort in cold months | Yes, app-controlled | Yes, remote-controlled | Yes, remote-controlled |
| Warm Air Dryer | Reduces toilet paper use | Yes, adjustable | Yes, adjustable | Yes, adjustable |
| Auto Open/Close Lid | Convenience and hygiene | Yes, proximity sensor | Yes, motion-activated | No |
| Self-Cleaning | Hygiene and maintenance | eWater+ electrolyzed | Wand self-clean | Wand self-clean |
| Deodorizer | Odor control | Yes, built-in air purifier | Yes | Yes |
| App Control | Customization and updates | Yes, polished app | Yes, Konnect app | No |
| Voice Assistant | Smart home integration | No | Alexa, Google Home | No |
| Flush Rating | Water efficiency | 1.0 GPF | 1.28 GPF | N/A (retrofit) |
| Warranty | Peace of mind | 3 years | 3 years | 3 years |
The Bottom Line on Features: If you want the full experience—app control, auto lid, air purification—you'll need to spend $3,000 or more. If you just want the core bidet functions with a heated seat, a retrofit seat like the BB-2000 is the smarter buy.
Buying Guide: Who Should Buy a Smart Toilet?
Who Should Buy
Homeowners remodeling a bathroom: If you're already tearing out walls and replacing fixtures, adding a smart toilet is a no-brainer. The cost is easier to absorb when bundled with a renovation, and you'll recoup some value when you sell (buyers increasingly expect at least a bidet seat in upscale homes).
People with mobility issues: Smart toilets are a game-changer for anyone with limited mobility. Auto-open lids, remote controls, and self-cleaning functions reduce physical strain and improve hygiene.
Eco-conscious households: Smart toilets use less water than traditional models and dramatically reduce toilet paper consumption. Over time, that adds up.
Tech enthusiasts: If you love your smart home ecosystem, a smart toilet is the final piece of the puzzle. Just temper your expectations—voice control is a novelty, not a necessity.
Who Should Skip
Renters with no intention of buying: Unless you go with a retrofit seat you can take with you, installing a full smart toilet in a rental is a bad investment.
Anyone on a tight budget: A $1,100 bidet seat delivers 80% of the experience. Don't stretch yourself thin for features you won't use.
People with older plumbing: Tankless smart toilets require adequate water pressure and a nearby outlet. If your bathroom isn't wired for it, factor in the cost of an electrician.
Budget Considerations
- Under $1,500: Retrofit bidet seats. You'll get warm water, heated seats, and dryers, but no integrated design or app control.
- $1,500–$4,000: Entry-level integrated smart toilets. Expect reliable bidet functions, auto flush, and basic smart features.
- $4,000–$10,000+: Premium models with all the bells and whistles. You're paying for design, advanced hygiene tech, and brand prestige.
Don't forget ongoing costs: electricity for heating water and seats (roughly $30–$60 per year), replacement filters for deodorizers, and potential plumbing adjustments.
Installation & Smart Home Integration
Installation
Retrofit bidet seats: These are DIY-friendly. Most attach to your existing toilet's water line and require a standard GFCI outlet nearby. Expect 30–60 minutes of work with basic tools.
Integrated smart toilets: These are a different beast. You'll need:
- A dedicated electrical outlet within reach of the toilet (ideally on a GFCI circuit)
- Adequate water pressure (check your home's PSI; most models need 20+ PSI)
- Possibly a plumber to handle the install, especially for tankless models
Professional installation typically runs $200–$500. In some states, installing a new toilet requires a permit—check local codes before you start.
Smart Home Integration
Here's the honest truth: smart toilet integration with your broader smart home is still limited. The Kohler Numera supports Alexa and Google Home, but the commands are basic ("flush the toilet" is not one of them, thankfully). TOTO's app is excellent but closed off from third-party ecosystems.
What you can expect:
- App control: Adjust settings, save profiles, monitor water usage
- Voice assistants: Limited to on/off functions and status checks on select models
- Automation: Some models can trigger bathroom lights or exhaust fans via IFTTT or manufacturer-specific hubs
If deep smart home integration is your priority, wait a generation or two. The category is evolving fast, and 2027 models will likely offer Matter support.
Conclusion & Final Verdict
Smart toilets have officially graduated from novelty to genuinely useful home appliances. After three months of testing, I can say with confidence that the best models improve hygiene, reduce toilet paper waste, and make the bathroom a more pleasant place to be. The question isn't whether smart toilets are good—it's whether they're good for you.
My final recommendations:
- Best Overall: TOTO Neorest NX2 — Unmatched performance and hygiene tech, if you can stomach the price.
- Best Value: Kohler Numera — The smart toilet most people should buy. Premium features, reasonable price.
- Best Budget: Bio Bidet Bliss BB-2000 — The perfect entry point for the smart-curious.
The Verdict: If you're remodeling or have the budget, a smart toilet is a worthwhile investment that you'll appreciate every single day. If you're on the fence, start with a retrofit bidet seat. You can always upgrade later—and once you experience a heated seat in January, you won't want to go back.
Rating: 4.5/5 — The technology is mature, the benefits are real, and the prices are finally starting to make sense. The only thing holding smart toilets back is the upfront cost and installation complexity. But for those who take the plunge, there's no going back to the cold, dumb toilets of yesterday.
