The Best Smart Toilets of 2026: A Complete Buyer's Review
Introduction
The bathroom has quietly become one of the most upgraded rooms in the modern American smart home. In 2026, smart toilets have moved from luxury novelty to genuinely practical fixtures, offering heated seats, bidet washing, automatic lids, and even health-tracking sensors. If you've ever winced at a cold seat on a winter morning or wondered whether your plumbing could tell you something about your health, this is the category for you. We spent weeks testing and researching the leading models to find the smart toilets that actually earn their price tags. This review breaks down our top three picks, the features that matter most, and everything you need to know before you buy. Whether you're remodeling or simply want a smarter throne, we've got you covered.
Our Top 3 Smart Toilet Recommendations
1. Toto Neorest NX2 — Best Overall Smart Toilet
Toto has long been the gold standard in Japanese bidet technology, and the Neorest NX2 represents the brand's most refined residential offering to date. From the moment you approach, the lid glides open automatically thanks to a proximity sensor, and the seat warms to your preferred temperature before you even sit down. The bidet functions are where Toto truly shines: the ewater+ system uses electrolyzed water to sanitize the wand and bowl after every use, and the oscillating, pulsating spray patterns feel genuinely pampering rather than gimmicky.
The NX2's Tornado Flush system is both powerful and remarkably quiet, using as little as 0.8 gallons per flush while still meeting rigorous performance standards. The integrated nightlight, deodorizer, and remote control round out a package that feels premium in every respect. It's also one of the most energy-efficient models we tested, with an automatic energy-saving mode that learns your usage patterns.
The main drawback is the price. At an estimated $8,500–$10,000 in 2026, the NX2 is a serious investment, and professional installation is strongly recommended. But if you want the best and plan to stay in your home for years, this is the one to beat. It's the closest thing to a spa experience you can install in a powder room.
Pros: Exceptional bidet performance, self-cleaning wand, quiet flush, energy-efficient Cons: Very expensive, requires professional installation, needs a nearby outlet
2. Kohler Numera — Best Smart Toilet for Health Tracking
Kohler's Numera takes a different approach, positioning itself as a wellness device as much as a toilet. Its built-in sensors analyze urine composition and can track hydration, electrolyte balance, and other biomarkers, syncing the data to the Kohler Health app. For anyone managing a chronic condition or simply curious about daily wellness trends, this is a genuinely novel capability that no other mainstream brand matches at this level.
Beyond the health tech, the Numera is a capable performer. It offers a heated seat, adjustable bidet spray, a warm-air dryer, and a self-cleaning stainless steel wand. The flush is efficient and the design is sleek and modern, with a low-profile tank that fits well in contemporary bathrooms. The app experience is polished, though we'd like to see more integration with third-party health platforms like Apple Health.
At roughly $6,000–$7,500, the Numera is priced below the Toto flagship but still firmly in premium territory. If health monitoring is a priority, it's worth the premium. If not, you can find comparable bidet comfort for less.
Pros: Unique health-tracking sensors, elegant design, solid bidet performance Cons: Health data ecosystem is still maturing, expensive, app could integrate more broadly
3. Bio Bidet Discovery DLS — Best Value Smart Toilet
For buyers who want most of the flagship experience without the five-figure price, the Bio Bidet Discovery DLS is our value champion. Priced around $2,200–$2,800 in 2026, it delivers a heated seat, warm-water bidet with multiple spray modes, a warm-air dryer, and a wireless remote. The tankless design saves space and delivers a consistent, powerful flush.
What impresses us most is how little you sacrifice. The stainless steel nozzle self-cleans, the seat temperature is adjustable, and the nightlight is a thoughtful touch for late-night trips. It doesn't have the health sensors or the ultra-quiet flush of the Toto, and the build quality is a step below the premium brands, but for the money it's hard to argue with.
Installation is more DIY-friendly than the top-tier models, though you'll still need a GFCI outlet near the toilet. For most households, the Discovery DLS offers the best balance of features, comfort, and price.
Pros: Excellent value, tankless design, full bidet feature set, easier installation Cons: No health tracking, louder flush than premium models, plastic components feel less substantial
Key Features to Consider
Before you buy, it helps to understand what separates a good smart toilet from a great one. The table below compares our three top picks across the features that matter most.

|---|---|---|---|
| Estimated Price (2026) | $8,500–$10,000 | $6,000–$7,500 | $2,200–$2,800 |

| Warranty | 3 years | 3 years | 3 years |
Bidet performance. Look for adjustable water temperature, pressure, and spray position. Oscillating and pulsating modes add comfort. A self-cleaning stainless steel wand is a must for hygiene.
Heated seat and dryer. These are the features you'll use every day. Variable temperature control matters more than you'd think, especially in colder climates.
Flush technology. Tankless designs save space and deliver consistent pressure, but they require adequate water supply. Check the flush rating and noise level if your bathroom is near a bedroom.
Smart features. Auto open/close lids, nightlights, and deodorizers are conveniences that add up. App connectivity and health tracking are nice-to-haves that justify a premium only if you'll actually use them.
Power requirements. Every smart toilet needs a grounded GFCI outlet within reach of the unit. If you don't have one, factor in the cost of an electrician.
Buying Guide: Who Should Buy a Smart Toilet?
A smart toilet isn't for everyone, and that's okay. Here's how to decide.
You should buy one if: You're remodeling a bathroom and want to future-proof it; you have mobility limitations and would benefit from hands-free operation and bidet washing; you value hygiene and comfort; or you're interested in wellness tracking and want to start with the data you generate daily.
You might skip it if: Your budget is tight and a bidet seat attachment (typically $200–$600) would meet your needs; you're renting and can't modify the plumbing or electrical; or you simply don't use the features you'd be paying for.
Budget considerations. Smart toilets range from about $1,000 for entry-level integrated models to well over $10,000 for flagship units. Don't forget installation, which can run $300–$800 for professional plumbing and electrical work if your bathroom isn't already set up. Also consider ongoing costs: electricity usage is modest, but replacement parts and filters (if applicable) add up over time. As a rule of thumb, spend on the features you'll use daily—heated seat, bidet, and reliable flush—before splurging on health sensors or app integration.
A note on bidet seats vs. full smart toilets. If you love your current toilet and it's in good condition, a high-end bidet seat can deliver 80% of the experience for a fraction of the cost. A full smart toilet makes sense when you're replacing an aging fixture or remodeling anyway.
Installation & Smart Home Integration
Installing a smart toilet is more involved than swapping out a standard model. You'll need a dedicated electrical outlet (GFCI-protected) near the toilet, a standard water supply line, and enough clearance for the unit's footprint. Most manufacturers recommend professional installation, and we agree—especially for tankless models that require precise water pressure and drainage. Expect the job to take two to four hours for a plumber or handyman.
Once installed, integration with your smart home varies by brand. Toto and Kohler both offer apps that let you customize settings, monitor usage, and receive maintenance alerts. Kohler's ecosystem plays more nicely with broader smart home platforms, and its health data can be exported for review. Neither brand offers deep integration with Alexa or Google Home for core functions—you won't be flushing with your voice anytime soon—but app-based control and scheduling are standard.
For most users, the "smart" in smart toilet is really about automation: the lid opens when you approach, the seat warms before you sit, and the bidet remembers your preferences. That's the experience worth paying for, and it works reliably without any hub or subscription.
Conclusion & Final Verdict
Smart toilets have matured into genuinely useful fixtures, and 2026 is a great year to buy. Our top pick, the Toto Neorest NX2, remains the benchmark for performance, hygiene, and refinement—if your budget allows, it's the one we'd choose. The Kohler Numera is the most interesting alternative, offering health-tracking capabilities that hint at where the category is heading. And the Bio Bidet Discovery DLS proves you don't need to spend five figures to enjoy heated seats, warm-water washing, and a warm-air dryer.
Whichever you choose, focus on the features you'll use every day, confirm your electrical setup before you buy, and budget for professional installation. A smart toilet is a long-term investment in comfort and hygiene—and once you've made the switch, you'll wonder how you ever lived without one. For most American households upgrading in 2026, the Bio Bidet Discovery DLS offers the smartest entry point, while the Toto Neorest NX2 is the ultimate destination.
