Best Smart Toilets of 2026, Ranked

A smart toilet builds the washing, drying, seat heating and flushing into one connected fixture, so the bowl rinses you with warm water, dries with warm air, lifts its lid as you approach and flushes on its own. We ranked the best smart toilets of 2026 by their flushing power and MaP flush-test scores, EPA WaterSense water use, washlet and dryer performance, auto features that actually work, and the patterns across thousands of aggregated owner reviews, so you can buy an integrated toilet that cleans well, saves water and earns its higher price.

Why Trust Best Flushing Toilets

  • Flushing power and MaP flush-test scores
  • Water efficiency (GPF and EPA WaterSense)
  • Aggregated owner reviews
  • Clog resistance and trapway design
  • Brand reliability and warranty

Quick Answer

The TOTO Neorest NX2 is the best smart toilet for most buyers. It pairs a dual Tornado flush reaching an 800-gram MaP score on 0.8 or 1.0 gallons with TOTO's Actilight self-cleaning system, a warm-water washlet, auto open and flush, and the brand's proven reliability. For the same integrated experience at a far lower price, the Woodbridge B0970S is the standout value smart toilet.

A smart toilet, also called an integrated toilet or a one-piece bidet toilet, folds a whole bathroom routine into a single connected fixture. Instead of a plain bowl and a separate seat, the unit builds in a heated seat, a retractable washing wand that rinses you with adjustable warm water, a warm-air dryer, a deodorizer, automatic lid and seat motion, and an automatic flush that fires when you stand or step away. Many add a night light, a soft-close lid, a remote or app control, and a self-cleaning cycle that mists the wand and the bowl between uses. The appeal is obvious the first time you use one: you finish, the toilet washes and dries you, then flushes and closes itself, and the seat is warm every time you sit down.

The catch is that a smart toilet is a bowl and an electronics package fused together, and a beautiful feature list means nothing if the underlying flush is weak or the electronics fail early. A cheap integrated unit can streak the bowl, flush poorly, lose its wash function after a year, or strand you with a non-standard part that no plumber stocks. A well-built smart toilet solves all of that: it flushes as hard as a strong standard toilet, runs on low dual-flush water use, survives daily power and water cycling, and comes from a brand with parts you can actually buy. We do not install or test these toilets ourselves. Instead we compare published manufacturer specifications, independent MaP (Maximum Performance) flush-test grams, EPA WaterSense certification, washlet and dryer ratings, electrical and warranty terms, and the patterns across thousands of verified owner reviews. Every model below pairs genuine smart features with a strong, efficient flush and a brand you can trust to be around. If you want the full performance-first ranking across every toilet type, start with our guide to the best flushing toilets.

What Is a Smart Toilet?

A smart toilet is an integrated, electrically powered fixture that builds a heated seat, a warm-water washlet, a warm-air dryer, a deodorizer, automatic lid and seat motion, and an automatic flush into one connected bowl. The best smart toilets, like the TOTO Neorest NX2 and Kohler Numi 2.0, also self-clean the bowl and wand and reach 800-gram MaP scores on a dual flush of 1.0 gallons or less. They replace both a standard toilet and a separate bidet seat in a single unit.

How We Research and Rank Smart Toilets

Every toilet here had to be a true integrated smart toilet, with at least a heated seat, a warm-water washlet and an automatic or self-cleaning function built into the bowl, then prove three things: a flush strong enough to clear the bowl in one pass, electronics reliable enough to survive daily cycling, and a brand with parts and support you can reach. We ranked first on independent MaP flush-test grams, since that is the only number that measures real waste clearance rather than marketing claims, then on washlet and dryer quality, dual-flush water use against EPA WaterSense, self-cleaning technology, electrical safety and warranty, and the weight of aggregated owner reviews. We favored units with proven flush engines, accessible parts and clear warranty terms, because a smart toilet that loses its wash function or floods its electronics is a poor buy at any price. Most picks here rate 600 to 800 grams on MaP against the 350-gram residential pass threshold, run at 1.28 gallons or less on a full flush, and carry a GFCI-protected power connection. We weighted verifiable specs and owner feedback over brand hype, and we do not take payment for placement. The table below summarizes how the picks compare on the numbers that decide a smart toilet purchase.

The 8 Best Smart Toilets, Reviewed

TOTO Neorest NX2 smart toilet

Best Overall

TOTO Neorest NX2

4.7 Most buyers

The Neorest NX2 is the smart toilet we recommend to most buyers because it gets the hard part right first: it flushes as cleanly as TOTO's best standard toilets despite carrying a full electronics package. It pairs a dual Tornado flush that reaches an 800-gram MaP score on 0.8 or 1.0 gallons with TOTO's Actilight self-cleaning system, a warm-water washlet, automatic lid and flush, and an air deodorizer.

Flush TypeDual, Tornado siphon jet
GPF0.8 / 1.0
MaP Score800 grams
Bowl HeightComfort height, elongated
Warranty1-year limited electronics
Best For
  • A complete hands-free wash, dry and flush routine
  • A strong 800-gram flush in an integrated toilet
  • Buyers who want TOTO reliability and self-cleaning
Not Ideal For
  • Tight budgets, since it is a premium fixture
  • Bathrooms with no nearby GFCI outlet

The Neorest NX2 uses TOTO's dual Tornado flush, which fires water through angled nozzles to create a swirling rinse that scours the full bowl wall, paired with the eWater+ and Actilight system that mists the bowl and wand with electrolyzed water and uses a UV-activated glaze to break down residue between uses. That combination is what keeps an integrated bowl clean despite the wand and sensors crowded around it. The CeFiONtect glaze helps waste and minerals slide away, so the bowl resists the streaking that plagues cheaper smart units.

Owner reviews are consistent on clean single-flush clearance, a warm and adjustable washlet spray, and reliable auto open, flush and close. The seat heats evenly and the night light and remote work as described. The main feedback is the high price and the need for a grounded outlet near the toilet, since the electronics require GFCI power. For an integrated toilet that does not compromise on flush or reliability, this is the default pick, and it also appears among the best Japanese toilets and washlets of 2026.

Expert Take

If you want one safe smart toilet and do not want to gamble on off-brand electronics, buy the Neorest NX2. You get TOTO's proven Tornado flush, a self-cleaning bowl and wand that keep maintenance low, and a washlet that actually stays comfortable and reliable for years. The only real costs are the upfront price and running a GFCI outlet to the toilet, both of which are one-time.

Check price on Amazon
Bottom Line: The most complete smart toilet, pairing an 800-gram dual Tornado flush with self-cleaning and a reliable warm-water washlet.

Best Value

Woodbridge B0970S

4.5 Affordable integrated toilet

The Woodbridge B0970S is the smart toilet to pick when you want the full integrated experience without paying premium-brand prices. It bundles a heated seat, a warm-water washlet with adjustable spray, a warm-air dryer, auto open, auto flush and a night light into one bowl that runs a dual flush at 0.8 or 1.28 gallons and reaches a 600-gram MaP score.

Best For
  • The full smart feature set at a value price
  • Heated seat, warm wash and dryer in one bowl
  • Buyers trying integrated toilets for the first time
Not Ideal For
  • Buyers who want a top-tier 800-gram MaP score
  • Homes wanting the deepest long-term parts support

The value case here is strong: you get nearly the entire smart toilet feature list, including the auto lid, foot-sensor flush, heated seat and warm-water wash, for a fraction of what a Neorest or Numi costs. The dual flush gives a genuine water saving on the 0.8-gallon partial, and the 600-gram MaP score covers a typical household. The bowl is a one-piece skirted design that wipes clean easily around the base.

Owners consistently praise the value and the breadth of features, noting you get a complete integrated toilet for the price of a mid-range standard model plus a separate bidet seat. Woodbridge is a younger brand than TOTO or Kohler, so the electronics reliability and parts depth are not as proven over the long term, and confirming the exact model number matters since Woodbridge sells several similar units. For the most features per dollar, it is the value standout, and it suits buyers cross-shopping the best toilet bidet combos of 2026.

Expert Take

If you want to try a smart toilet without spending what a premium unit costs, the B0970S is the value buy. Go in knowing you are trading a marquee brand's proven electronics longevity for the lower price and nearly the same feature list, which is a fair deal for most home bathrooms and an easy upgrade from a basic toilet plus bidet seat.

Check price on Amazon
Bottom Line: The best value smart toilet, delivering nearly the full integrated feature set for far less than the premium brands.
Kohler Numi 2.0 smart toilet
3
Most Advanced

Kohler Numi 2.0

4.5 Tech-forward bathrooms

The Numi 2.0 is Kohler's flagship smart toilet, built for buyers who want the deepest technology in the category: voice control through Amazon Alexa, a built-in speaker, ambient lighting, personalized user presets and an app, all wrapped around a strong dual flush. It reaches an 800-gram MaP score on 0.8 or 1.28 gallons, so the connected features sit on top of a genuinely capable bowl.

Flush TypeDual, gravity siphon
GPF0.8 / 1.28
MaP Score800 grams

Best For
  • Voice, app and personalized user presets
  • A bold, angular designer look with lighting
  • Buyers who want the most connected toilet
Not Ideal For
  • Buyers who want simple, no-app operation
  • The tightest budgets, since it is top-tier

The Numi 2.0 leans into smart-home integration further than any rival. You can store wash, dry, lighting and music presets per user, trigger functions by voice through Alexa, and control everything from the Kohler app or the dedicated touchscreen remote. The angular, vault-like body is a deliberate design statement, and the ambient lighting and speaker make it the showpiece of a high-end remodel.

Owners praise the feature depth and the strong, quiet flush, with the most common feedback being that the technology has a learning curve and the remote and app are central to operation, so a buyer who wants plain push-button simplicity may find it busy. As a flagship it sits at the top of the price range. For the most advanced, most connected smart toilet that still flushes at 800 grams, the Numi 2.0 is the pick, and it stands out among the best self-cleaning toilet designs.

Expert Take

The Numi 2.0 is the smart toilet I point tech-forward clients to, because nothing else integrates voice, app control and per-user presets this deeply while keeping a real 800-gram flush. Just be honest about how you will use it: if you love smart-home gear, you will enjoy the depth, but if you want a toilet that simply washes and flushes without an app, a simpler Neorest or Woodbridge fits better.

Bottom Line: The most advanced smart toilet, layering voice, app and per-user presets over a strong 800-gram dual flush.
TOTO Neorest RH smart toilet

Strongest Flush

TOTO Neorest RH

4.6 Maximum flush power

The Neorest RH is the smart toilet to pick when clearing power is your priority. It uses TOTO's dual Tornado flush with a deep, wide siphon-jet trapway, driving a forceful swirling rinse on a 0.9 or 1.28 gallon flush that reaches an 800-gram MaP score, the top of the smart-toilet class, while still delivering the full washlet, dryer and self-cleaning package.

Flush TypeDual, Tornado siphon jet

Best For
  • The strongest single-flush clearance in a smart toilet
  • Households that have had clog problems before
  • Buyers who want TOTO self-cleaning and eWater+
Not Ideal For
  • Buyers on a strict budget
  • Bathrooms without a nearby grounded outlet

The Neorest RH combines TOTO's strongest integrated flush engine with the same eWater+ and Actilight self-cleaning found on the NX2. The deep siphon-jet trapway and dual Tornado nozzles give an unusually forceful, clean clearance for a smart toilet, where the crowded electronics around the bowl can otherwise compromise the flush path. The CeFiONtect glaze keeps the bowl smooth and stain-resistant between the automatic mist cycles.

Owners rate the flush as powerful and rarely needing a second pass, with the same warm washlet, dryer and auto functions as the NX2. The main feedback is the premium price and, as with any smart toilet, the GFCI outlet requirement. For a buyer who wants the hardest-flushing integrated toilet without dropping the smart features, the Neorest RH is the pick, and it earns a place among the strongest flushing toilets of 2026.

Expert Take

When a client wants a smart toilet but worries the electronics will mean a weak flush, the Neorest RH is what I show them. Its deep Tornado siphon-jet trapway gives the strongest, cleanest clearance in the integrated class, so it answers the one real objection to smart toilets while keeping the full wash, dry and self-cleaning experience.

Check price on Amazon
Bottom Line: The hardest-flushing smart toilet here, combining a deep Tornado siphon-jet trapway with the full self-cleaning washlet package.
Kohler Veil Intelligent smart toilet

Designer Look

Kohler Veil Intelligent

4.5 Clean skirted design

The Veil Intelligent is Kohler's sleeker, more restrained smart toilet, built around a fully skirted one-piece body with a low, continuous profile that suits a clean modern bathroom. It delivers a heated seat, warm-water washlet, warm-air dryer, auto open and flush, and a dual flush that reaches an 800-gram MaP score on 0.8 or 1.28 gallons.

Flush TypeDual, gravity siphon
GPF0.8 / 1.28

  • A clean skirted look without the Numi's bulk
  • Strong 800-gram flush in a low-profile body
  • Buyers who want Kohler quality, simpler controls
Not Ideal For
  • Buyers who want voice and app integration
  • Tight budgets, since it is a premium fixture

The Veil Intelligent is the smart toilet for buyers who want Kohler engineering and a strong 800-gram flush but find the Numi's angular body and deep tech too much. The skirted one-piece form wipes clean easily around the base, the heated seat and warm wash cover the daily essentials, and the auto lid and flush handle the hands-free routine without an app at the center of operation.

Owners praise the understated look and the strong, quiet flush, noting the controls are simpler than the Numi while still covering wash, dry and auto functions. As a premium fixture it costs more than the value picks and needs a GFCI outlet. For a buyer who wants a designer skirted smart toilet that flushes hard without the maximalist tech, the Veil Intelligent is the balanced choice, and it fits alongside the best skirted toilet designs.

Expert Take

The Veil Intelligent is the smart toilet I steer buyers toward when they want Kohler quality and an 800-gram flush but find the Numi too busy. You get the clean skirted body, the warm wash and dryer, and the auto lid and flush, with controls that stay simple, which suits most home bathrooms better than a voice-and-app showpiece.

Bottom Line: The best-looking restrained smart toilet, pairing a clean skirted body with a strong 800-gram dual flush.

Budget Bidet

Swiss Madison Vivante

4.4 Lowest-cost integrated unit

The Swiss Madison Vivante is the budget way into a true integrated smart toilet, bundling a heated seat, a warm-water washlet, a warm-air dryer, a soft-close lid and a remote into a modern one-piece bowl. It runs a dual flush at 0.8 or 1.28 gallons and reaches a 600-gram MaP score, enough for a typical household at a price well below the premium brands.

  • Buyers wanting smart features on a tight budget
Not Ideal For
  • Buyers who want a top-tier 800-gram MaP score
  • Homes wanting the deepest parts support

The appeal is getting the core integrated experience, the heated seat, warm wash, warm-air dryer and remote, in one matched bowl for the least money. The dual flush gives a real water saving on the 0.8-gallon partial, and the 600-gram MaP score handles normal home use. The modern one-piece body wipes clean around the base and suits a contemporary bathroom.

Owners praise the value and the look, noting you get a full integrated bidet toilet for the price of a mid-range standard model plus a basic bidet seat. Swiss Madison is a younger brand than TOTO or Kohler, so the electronics longevity and parts depth are not as proven, and a few owners note the dryer is gentler than a premium unit. For the lowest-cost path to a real smart toilet, it is the budget standout, and it suits buyers cross-shopping the best Swiss Madison toilets.

Expert Take

The Vivante is the budget pick I point to when someone wants a real integrated smart toilet, not just a bidet seat, but cannot justify a premium price. Buying it as a complete unit avoids mismatched parts, and the 600-gram flush is fine for a normal home; just accept a shallower parts network and a gentler dryer as the price of the savings.

Bottom Line: The best budget smart toilet, bundling a heated seat, warm wash and dryer in one bowl for the least money.
TOTO Washlet S7A seat with Drake toilet

Build Your Own

TOTO Drake + Washlet S7A

4.7 Smart features on a proven bowl

The smartest move for many buyers is not an all-in-one unit at all, but a proven TOTO Drake bowl paired with TOTO's Washlet S7A heated bidet seat. The Drake gives an 800-gram MaP flush, and the S7A adds a warm-water washlet, warm-air dryer, heated seat, deodorizer, auto open and eWater+ self-cleaning, turning any compatible bowl into a smart toilet.

  • Smart features on a proven, serviceable bowl
  • Replacing only the seat if electronics ever fail
  • Buyers who want flexibility and easy parts
Not Ideal For
  • Buyers who want a seamless one-piece look
  • Anyone wanting a fully automatic flush

The build-your-own approach has a real advantage over an integrated unit: if the electronics ever fail, you replace only the Washlet seat, not the whole toilet, and the Drake bowl underneath uses standard, widely stocked parts. The S7A is one of TOTO's top washlet seats, with an instant warm-water heater, an air dryer, a heated seat, a deodorizer, auto lid and the eWater+ misting that keeps the wand and bowl clean.

Owners rate the Drake as one of the most reliable flushers TOTO makes, and the S7A as a near-flagship bidet seat at a lower combined cost than a sealed smart toilet. The tradeoff is the look: it reads as a bowl with a thick smart seat rather than a seamless integrated body, and the flush stays manual rather than fully automatic. For smart features on a serviceable, proven base, this combination is the smart pick, and the bowl itself is covered in our TOTO Drake review.

Expert Take

The build-your-own Drake plus Washlet S7A is the setup I recommend to buyers who love smart features but worry about being stranded if the electronics die. You keep a proven, widely serviceable bowl, and the day a washlet ever fails you swap the seat, not the toilet. You give up the seamless one-piece look, which is a fair trade for the reliability and easy repairs.

Tankless Look

Woodbridge B0980S

4.4 Low-profile modern bathrooms

The Woodbridge B0980S is the value pick for buyers who want the sleek, low-profile look of a tankless-style smart toilet without the premium price. It uses an integrated electric flush with a low, seamless body, a heated seat, a warm-water washlet, a warm-air dryer and auto functions, running a dual flush at 0.8 or 1.28 gallons for a 600-gram MaP score.

Not Ideal For
  • Buyers who want a top-tier 800-gram MaP score
  • Homes with low water pressure for electric flush

The B0980S delivers the sleek, low-slung profile that buyers want from a modern smart toilet, with the tank height minimized into the integrated body so it reads almost tankless. It carries the full smart feature set, including the heated seat, warm wash, warm-air dryer and auto lid and flush, and the dual flush keeps water use low on the 0.8-gallon partial.

Owners praise the modern look and the value, noting you get a near-tankless integrated toilet for far less than a premium one. Like all electric-assisted designs it needs adequate household water pressure and a GFCI outlet, and as a younger brand Woodbridge does not match TOTO or Kohler on long-term parts depth. For the low-profile modern look at a value price, the B0980S is the pick, and buyers chasing that seamless body should also see the best tankless toilets for modern homes.

Expert Take

The B0980S is the value pick I point to when someone loves the sleek, near-tankless smart toilet look but cannot justify a premium price. You get the seamless low body and the full feature set; just confirm your home has solid water pressure for the electric-assisted flush and a grounded outlet, and accept a shallower parts network as the cost of the savings.

Check price on Amazon
Bottom Line: The best value near-tankless smart toilet, delivering a low, seamless body and full feature set for far less than the premium brands.
Expert Take

Across this whole list, the part that decides long-term satisfaction is whether the flush and the electronics are both built to last, not the length of the feature list. A smart toilet with a weak bowl streaks no matter how good the washlet is, and one with fragile electronics becomes an expensive plain toilet the day the wash function dies. If you want one safe choice, the TOTO Neorest NX2 gets both right with a proven flush and self-cleaning. If you want the smart experience but hate the idea of being stranded by failed electronics, build your own with a TOTO Drake bowl and a Washlet S7A seat, so the day anything fails you replace only the seat.

Which Smart Toilet Has the Strongest Flush?

The TOTO Neorest RH has the strongest flush among smart toilets, using a deep dual Tornado siphon-jet trapway to reach an 800-gram MaP score on a 0.9 or 1.28 gallon flush. The TOTO Neorest NX2 and Kohler Numi 2.0 match the same 800-gram score, which is the practical ceiling for an integrated toilet where the wand and electronics crowd the bowl. Smart toilets rated 600 grams, like the Woodbridge and Swiss Madison value units, still handle a normal household.

Flush power is the one area where buyers worry a smart toilet might fall short, because the washing wand, sensors and wiring crowd the flush path. The best brands engineer around it. TOTO's Tornado nozzles and deep siphon-jet trapways, and Kohler's tested gravity systems, reach 800 grams, which clears a typical household in one pass. If raw clearance across every toilet type is your priority, see our ranking of the strongest flushing toilets of 2026.

What Is the Best Smart Toilet for Preventing Clogs?

The TOTO Neorest RH and NX2 are the best smart toilets for preventing clogs, pairing an 800-gram MaP score with a fully glazed, wide siphon-jet trapway that passes waste cleanly in one flush. TOTO's eWater+ and CeFiONtect glaze also keep the bowl smoother between uses, so residue is less likely to catch. For any smart toilet, prioritize the highest MaP score paired with a glazed trapway.

Clog resistance in a smart toilet depends on the same factors as any toilet, trapway diameter and glaze, plus one integrated-specific point: the flush must stay strong despite the crowded electronics. A glazed trapway lets waste slide instead of catching, and a self-misting bowl keeps the surface clean between uses. A smart toilet rated below 600 grams on MaP is more likely to need a second flush, so treat 800 grams as the target for heavy use. If recurring clogs are your concern, also see our picks for toilets that never clog.

Are Smart Toilets Worth It?

Smart toilets are worth it for buyers who want a hands-free wash, dry and flush routine, a heated seat and a self-cleaning bowl, and who have a grounded GFCI outlet near the toilet. The best models flush as strongly as standard toilets and replace both a toilet and a separate bidet seat. The main downsides are higher upfront cost, the need for power, and reliance on the brand for electronic parts, so buy from TOTO, Kohler, Woodbridge or Swiss Madison rather than an unknown maker.

The value case rests on real daily benefits: a warm-water wash that uses far less paper, a heated seat in cold months, a self-cleaning bowl that cuts scrubbing, and auto lid and flush that keep the toilet hands-free and more hygienic. The costs are the higher price, the need for a nearby GFCI outlet, and dependence on the brand if the electronics ever fail. That is why brand reliability matters more here than on a basic toilet, and why a build-your-own TOTO Drake plus Washlet setup appeals to cautious buyers. For a broader view of fit and value across the category, our pillar on the best flushing toilets covers it in depth.

What Is a Good MaP Score for a Smart Toilet?

A MaP score of 600 grams handles a typical household and 800 grams is the practical ceiling for a smart toilet. Because the wand and electronics crowd the bowl, aim for at least 600 grams and choose 800 grams if heavy use or past clogs are a concern. The best integrated models, like the TOTO Neorest NX2 and RH and the Kohler Numi 2.0, reach 800 grams on a dual flush of 1.0 to 1.28 gallons.

MaP (Maximum Performance) is an independent test that measures how many grams of solid waste a toilet clears in a single flush, ignoring marketing language and measuring clearance directly. For smart toilets it is especially useful, because a long feature list can distract from a weak flush, so a published 800-gram score is real proof the integrated design did not compromise clearing power. A smart toilet with no published MaP score is a gamble worth avoiding no matter how impressive its features sound.

Buying advice

How to choose the best smart toilet

A smart toilet is a bowl and an electronics package fused together, so the right choice depends on the flush, the features and the support behind both. Understand these factors and you can pick an integrated toilet that cleans well, flushes hard and stays reliable for years.

Start with the flush and the MaP score

It is easy to be dazzled by a feature list and forget that a smart toilet still has to clear the bowl, and the crowded electronics make that harder, not easier. The MaP flush-test gram score is your proof the flush works. Treat 600 grams as the floor and 800 grams as ideal, which the TOTO Neorest models and Kohler Numi 2.0 reach. A wide, glazed siphon-jet trapway clears waste cleanly and resists clogs. A smart toilet with no published MaP score is a gamble, because a weak flush behind a glossy feature list will streak the bowl and need second flushes no matter how good the washlet is.

Tip: confirm you have a GFCI outlet near the toilet

Every smart toilet needs power, and most require a grounded, GFCI-protected outlet within a few feet of the unit for the heated seat, washlet heater, dryer and sensors. Before buying, confirm an outlet is present or budget for an electrician to add one, because routing power is the most common surprise for first-time smart toilet buyers. A nearby GFCI outlet is a code-friendly, safe way to supply the toilet, and planning it during a remodel is far cheaper than adding it afterward. If you want to test the washlet experience first, a build-your-own TOTO Drake plus Washlet S7A still needs the same outlet but lets you replace just the seat later, which is covered in our look at the best Japanese toilets and washlets of 2026.

Decide which smart features you will actually use

Smart toilets range from a heated seat and warm wash to voice control, app presets, speakers and ambient lighting, and you pay for every layer. Decide which features you will use daily before you buy. Almost everyone values the heated seat, warm-water washlet, warm-air dryer and auto lid and flush, which the Woodbridge and Swiss Madison value units cover. Voice, app and per-user presets, found on the Kohler Numi 2.0, suit smart-home enthusiasts but add cost and complexity that many buyers never touch. Self-cleaning systems like TOTO's eWater+ and Actilight genuinely cut maintenance and are worth prioritizing. Match the feature depth to how your household will really use the toilet rather than buying the longest list.

Weigh water use, flush type and seat fit

Most quality smart toilets use a dual flush, with a low 0.8 or 0.9 gallon partial for liquids and a 1.0 to 1.28 gallon full flush for solids, which keeps them EPA WaterSense certified and trims daily water use. A few electric-assisted designs need adequate household water pressure to flush their best, so confirm your supply if a unit relies on a pump. Also check the bowl height and shape: most smart toilets use a comfort-height elongated bowl, which suits tall users and seniors, but confirm the rough-in matches your drain so the unit fits. The warm-water wash also means you use far less paper, which compounds the water and comfort benefits over time.

Prioritize brand reliability and parts support

A smart toilet is only as good as the brand standing behind its electronics, because the day a washlet, dryer or auto flush fails, you depend on that maker for parts and service. TOTO and Kohler have the deepest networks and the longest track records on integrated toilets, which is why their premium units justify the price for buyers who plan to keep the toilet for a decade. Woodbridge and Swiss Madison deliver strong value and a full feature set, but with shallower long-term parts support, which is the tradeoff for the lower price. If reliability is your top worry, either buy a premium brand or build your own with a proven bowl and a replaceable washlet seat, so a failure costs a seat rather than the whole toilet.

Expert Take

The mistake I see most with smart toilets is buying on the feature list and ignoring the flush and the parts support. Filter first for a published 800-gram MaP flush, confirm you have a GFCI outlet, then choose between a premium brand for the deepest reliability or a build-your-own Drake-plus-Washlet setup for the easiest future repairs. Do those three things and your smart toilet will wash well, flush hard and stay serviceable for well over a decade instead of becoming an expensive plain bowl.

FAQ

Frequently asked questions

? What is the best smart toilet you can buy?

The TOTO Neorest NX2 is the best smart toilet for most buyers, pairing a dual Tornado flush that reaches an 800-gram MaP score on 0.8 or 1.0 gallons with TOTO's eWater+ and Actilight self-cleaning, a warm-water washlet, a heated seat and auto lid and flush. For the same integrated experience at a far lower price, the Woodbridge B0970S is the best value.

? What does a smart toilet actually do?

A smart toilet builds a heated seat, a warm-water washlet that rinses you, a warm-air dryer, a deodorizer, automatic lid and seat motion, and an automatic flush into one connected bowl. Many add a night light, a remote or app control, and a self-cleaning cycle that mists the wand and bowl. It replaces both a standard toilet and a separate bidet seat in a single fixture.

? Do smart toilets flush as well as standard toilets?

The best ones do. Because the wand and electronics crowd the bowl, flush engineering matters more, but top models like the TOTO Neorest RH and NX2 and the Kohler Numi 2.0 reach an 800-gram MaP score, which clears a typical household in one pass. Choose a smart toilet with a published MaP score of at least 600 grams, and 800 grams if you want standard-toilet flush strength.

? Do smart toilets need electricity?

Yes. Smart toilets require power for the heated seat, the washlet water heater, the dryer, the deodorizer and the sensors, so they need a grounded, GFCI-protected outlet within a few feet of the unit. This is the most common install surprise for first-time buyers, so confirm an outlet exists or budget for an electrician to add one before you buy.

? What happens to a smart toilet during a power outage?

Most smart toilets keep a manual flush option that works without power, but the washlet, dryer, heated seat and auto functions stop until power returns. TOTO Neorest and Kohler units include a manual flush button or lever for outages. If reliable flushing during outages is critical, confirm the model has a manual flush before buying.

? Are smart toilets hard to install?

They are more involved than a standard toilet because they need a nearby GFCI outlet in addition to the usual water supply and drain connections. The bowl mounts much like a one-piece toilet, but you must route power and confirm the rough-in matches your drain. If an outlet is already present, a competent DIYer can install one; if not, plan for an electrician.

? How much water does a smart toilet use?

Most quality smart toilets use a dual flush, with a low 0.8 or 0.9 gallon partial flush and a 1.0 to 1.28 gallon full flush, and many carry EPA WaterSense certification. The warm-water wash also cuts paper use. For the lowest water use, choose a dual-flush WaterSense smart toilet rather than an older 1.6 gallon design.

? Are smart toilets EPA WaterSense certified?

Many are. EPA WaterSense certifies toilets that use 1.28 gallons per flush or less while meeting strict performance standards, and most dual-flush smart toilets, including the TOTO Neorest NX2 and the Kohler Veil Intelligent, carry the label. Choosing a WaterSense smart toilet saves water on every flush without sacrificing clearing power.

? Is a smart toilet the same as a bidet toilet?

A smart toilet includes a bidet washlet, but it adds more: a heated seat, a warm-air dryer, a deodorizer, automatic lid and flush, and often self-cleaning and app control. A plain bidet toilet may only add a washing spray. Every smart toilet is a bidet toilet, but not every bidet toilet is fully smart.

? Can you buy a smart toilet seat instead of a whole smart toilet?

Yes, and it is often the smarter move. A washlet bidet seat like the TOTO Washlet S7A adds a warm-water wash, dryer, heated seat and auto functions to a proven standard bowl such as the TOTO Drake. The benefit is that if the electronics ever fail, you replace only the seat, not the whole toilet, and the bowl uses standard, widely stocked parts.

? Are smart toilets easy to clean?

Yes. Many smart toilets self-clean, misting the wand and bowl with electrolyzed or sanitized water between uses, and premium glazes like TOTO's CeFiONtect keep the surface smooth so residue slides away. The seamless one-piece bodies also wipe clean easily around the base. Self-cleaning is one of the main practical reasons buyers upgrade.

? Which brands make the most reliable smart toilets?

TOTO and Kohler have the deepest track records and parts networks on integrated smart toilets, which is why their premium units justify the price for long-term ownership. Woodbridge and Swiss Madison deliver strong value and a full feature set with shallower long-term support. For maximum reliability, choose TOTO or Kohler, or build your own with a proven bowl and replaceable washlet seat.

? Do smart toilets clog more than regular toilets?

No, not if you choose a model with a strong flush. The crowded electronics make flush engineering harder, but a smart toilet with an 800-gram MaP score and a wide glazed siphon-jet trapway, like the TOTO Neorest RH, resists clogs as well as any standard toilet. Avoid units with a low or unpublished MaP score, which are the ones more likely to clog.

? Are smart toilets good for seniors?

They can be excellent for seniors. The heated comfort-height seat eases sitting and standing, the warm-water wash and dryer reduce the reach and effort of cleaning, and the auto lid and flush remove manual steps. The hands-free, hygienic operation is a real benefit for limited mobility, which is why smart toilets often suit accessible bathrooms.

? Do smart toilets have a remote control?

Most do. A wall-mounted or handheld remote controls the wash, dryer, seat temperature, water pressure and position, and the auto functions. Premium units like the Kohler Numi 2.0 add app and voice control through Amazon Alexa, while value models keep a simpler remote. Confirm the control method suits your household, since some buyers prefer simple buttons over an app.

? How long do smart toilets last?

The ceramic bowl can last for decades like any toilet, but the electronics are the limiting factor and typically carry a one-year warranty, with realistic service life depending heavily on brand quality. Premium TOTO and Kohler units tend to last longest, while budget electronics may need attention sooner. Buying a replaceable washlet seat on a standard bowl extends usable life, since you renew only the seat.

? Can a smart toilet replace a separate bidet?

Yes. A smart toilet integrates the bidet washlet directly into the bowl, with adjustable warm-water position and pressure, plus a warm-air dryer that a standalone bidet usually lacks. It does the job of both a toilet and a bidet in one fixture, which saves space and avoids a second plumbing fixture in the bathroom.

? Do smart toilets need special plumbing?

No special plumbing beyond a standard water supply and drain, but they do need a nearby GFCI electrical outlet, which is the main extra requirement. The rough-in should match the unit, and the supply line connects to the integrated tank or pump. The electrical connection, not the plumbing, is what usually requires planning.

? Why is the seat on my smart toilet not heating?

A cold smart toilet seat usually points to the unit being unplugged, a tripped GFCI outlet, the seat heater being switched off in settings, or a temperature set too low. Check the outlet and reset the GFCI first, then confirm the heat setting on the remote. If power is present and the setting is correct but the seat stays cold, the heating element may need service under warranty.

? Are smart toilets worth the higher price?

For buyers who will use the daily comforts, a heated seat, warm-water wash, warm-air dryer and self-cleaning bowl, and who have a GFCI outlet nearby, a smart toilet is usually worth it, since it replaces both a toilet and a bidet seat. If you only want a wash function, a washlet seat on a proven bowl delivers most of the benefit for less and is easier to service.

Our Verdict

For an integrated toilet that washes, dries and self-cleans while still flushing hard, the TOTO Neorest NX2 is the pick: an 800-gram MaP dual Tornado flush on 0.8 or 1.0 gallons, paired with eWater+ and Actilight self-cleaning, a reliable warm-water washlet, and TOTO's deep parts network. Choose the TOTO Neorest RH if you want the strongest flush in the class, the Kohler Numi 2.0 for the deepest voice and app technology, the Woodbridge B0970S for the best value, or a build-your-own TOTO Drake plus Washlet S7A if you want smart features on a serviceable bowl you can repair seat-only. Confirm a GFCI outlet, your rough-in and the published MaP score before you buy, then check the current price on Amazon.
