The short answer: The TOTO Neorest AS Integrated Smart Toilet is the smart toilet most 2026 households should buy — EWATER+, Tornado Flush, and a price that fits real luxury-remodel budgets.
A smart toilet in 2026 buys you self-sanitizing bowls, heated seats, auto-flush, warm-water bidet wash, and — on the top end — a voice assistant living in your bathroom. The TOTO Neorest AS Integrated Smart Toilet lands at the intersection of TOTO's 40-plus-year bidet engineering, EWATER+, Tornado Flush, and a price — $5,500-$7,500 — where typical luxury-bathroom remodels actually land. If smart-home integration is your priority, the Kohler Numi 2.0 Smart Toilet is the only integrated unit with native Alexa and app control. If budget is the constraint, our best smart bidet toilet seats guide covers the $200-$650 bidet-seat attachment route — same core function, 10× lower price.
We aggregated 8+ expert sources per product across six integrated smart toilets — KBAuthority, CNN Underscored, Pursuitist, BidetKing, and manufacturer spec sheets — scored every candidate on our SHE Hygiene Automation Score rubric, and verified Amazon availability and pricing through the Amazon Creators API on 2026-04-18.

TOTO Neorest AS Integrated Smart Toilet
(Current Price, subject to change)
The TOTO Neorest AS is the integrated smart toilet most buyers should start with. It carries the two technologies that define TOTO's hygiene engineering — EWATER+, which mists the bowl and wand with electrolyzed water after every use, and Tornado Flush, a rimless bowl-cleaning system that aggregated reviewer panels (KBAuthority, BidetKing) consistently rank above Kohler's conventional flush. You get TOTO reliability without paying the Neorest NX2 ultra-flagship premium.
What it does not have: native voice, a branded app, or ambient lighting. The remote handles wash, seat, and flush; if you want Alexa in your bathroom, the Numi 2.0 is the pick. But reviewers found the AS's remote-plus-Washlet combination stays out of the way better than a smart-home unit that also wants to be a connected appliance. Analog beats firmware when a toilet has to last 10-15 years.
On our SHE Hygiene Automation Score the AS earns 8.2/10 — third highest on this list, but the "Best Overall" tag goes here because the NX2 costs 3× as much and the Numi 2.0 trades hygiene-tech points for smart-home integration most households do not need in a toilet.
What We Love
- EWATER+ self-sanitization — the bowl and bidet wand are misted with electrolyzed water after every use, reducing residue buildup and the need for chemical cleaners
- Tornado Flush — rimless bowl with swirling water pattern cleans visibly better than the flush systems reviewed on Kohler Veil and Bio Bidet Discovery DLX
- Dual 1.0 / 0.8 GPF flush — meets WaterSense without cutting bowl-clear performance
- Tankless instant warm water — never runs cold mid-cycle the way reservoir systems do
- 40-plus-year TOTO bidet engineering — reviewer benchmarks for long-term reliability
What Could Be Better
- No voice assistant or app control (remote only)
- ACTILIGHT UV sanitization reserved for the pricier NX2
- Installation requires a 120V GFCI outlet within 36 inches — budget an electrician if you don't have one
- Replacement parts route through TOTO dealers with 7-14 day lead times
The Verdict
Buy the TOTO Neorest AS Integrated Smart Toilet if you want the integrated smart toilet most households end up happy with after a luxury remodel — EWATER+ + Tornado Flush, TOTO reliability, and a price where the math still makes sense. If smart-home integration matters more than hygiene tech, jump to the Kohler Numi 2.0 Smart Toilet. If you're on a sub-$1,000 budget, the bidet seat attachment route is a better fit.

Kohler Numi 2.0 Smart Toilet — Best for Smart Home Integration
Kohler Numi 2.0 Smart Toilet
(Current Price, subject to change)
The Kohler Numi 2.0 Smart Toilet is the only integrated smart toilet on the 2026 market with native Amazon Alexa and a full manufacturer app. If you live inside a smart home ecosystem and you want the toilet to be part of it — hands-free flush via Alexa, wash presets saved in the Konnect app, ambient light that matches your morning routine — this is the only unit that delivers. Kohler's stainless-steel UV self-cleaning wand pulls the Numi's hygiene score into the "good enough" band, but the SHE Hygiene Automation Score of 8.4 is driven overwhelmingly by the smart-integration dimension (9.5/10) rather than self-cleaning (7.5/10).
What you're paying for at $12,999 is the integration, the Bluetooth speakers, the ambient lighting, and the hands-free choreography — not better bowl hygiene than the TOTO Neorest AS Integrated Smart Toilet. TOTO reviewers are explicit that EWATER+ outperforms Kohler's UV wand on residue reduction. The Numi wins when your priority is "I want my toilet inside Home Assistant," and it loses when your priority is "I want the bowl to sanitize itself."
One underrated feature: the emergency backup battery flushes the toilet during a power outage. No other toilet on this list does that — both Neorest models and the Kohler Veil Intelligent Toilet lose auto-flush when the power drops, leaving manual flush only.
What We Love
- Built-in Alexa + Kohler Konnect app — only integrated smart toilet with native voice and app, not a bolt-on hub
- Bluetooth speakers + ambient multicolor lighting — the "experience" layer that no other integrated toilet ships
- Motion-activated lid and hands-free flush — reduces touchpoints during cold/flu season
- Backup battery flush — the only unit on this list that flushes during a power outage
- Stainless-steel self-cleaning UV wand — plastic-nozzle bidets (like the Bio Bidet Discovery DLX Smart Toilet) cannot match this
What Could Be Better
- $12,999 before installation — only justifies at the high end of a remodel budget
- Alexa integration adds firmware-update risk that analog TOTO designs avoid
- Heavy one-piece install may require reinforced subfloor
- Repair calls route through Kohler dealers, not big-box plumbing
The Verdict
Buy the Kohler Numi 2.0 Smart Toilet if smart-home integration matters more than raw hygiene tech — you already own voice-first automation, you want a toilet that fits in, and $12,999 fits the remodel line item. If hygiene tech is the priority, go TOTO Neorest AS Integrated Smart Toilet and spend the $7,000 difference elsewhere in the bathroom.

TOTO Neorest NX2 Smart Toilet — Best Flagship / Luxury
TOTO Neorest NX2 Smart Toilet
(Current Price, subject to change)
The TOTO Neorest NX2 Smart Toilet is the top of TOTO's integrated-toilet range and — on pure hygiene technology — the highest-scoring product on this guide. ACTILIGHT is unique: a photocatalytic UV system that activates TiO₂ on the bowl surface under UV light to break down organic residue. Combined with EWATER+ misting and the Cyclone Rinse flush pattern, the NX2's Self-Cleaning Tech dimension scores a perfect 10 on our rubric. The SHE Hygiene Automation Score of 8.9 is the highest on this list.
So why isn't it "Best Overall"? Two reasons. First, price — $26,279 before installation is a category most bathroom remodels won't touch, and the incremental hygiene gain over the TOTO Neorest AS Integrated Smart Toilet is real but not 3× real. Second, smart-integration dimension: the NX2 scores just 5/10 because TOTO still doesn't ship voice or app on any Neorest. If you're paying top-of-market, the Kohler Numi 2.0 Smart Toilet gives you smart-home features the NX2 can't.
The NX2 earns its position as the flagship pick, not the default pick. Buy it when hygiene engineering is the top priority, when the 10-year ownership horizon justifies the outlay, and when you're doing a bathroom where every other fixture is at TOTO-flagship tier.
What We Love
- ACTILIGHT photocatalyst UV — the only integrated smart toilet on this list with UV-plus-photocatalyst sanitization
- EWATER+ + Tornado Flush + Cyclone Rinse — stacked hygiene tech no other product pairs
- Skirted one-piece design — conceals the trapway for easy exterior cleaning
- 10-year ownership horizon — TOTO flagship engineering and dealer service network
- Perfect 10/10 on Self-Cleaning Tech in our SHE Hygiene Automation Score rubric
What Could Be Better
- Top-of-market pricing at $26,279 restricts the audience to ultra-luxury remodels
- Installation typically requires a specialty plumber — expect $500-$1,200 labor on top
- Replacement parts only through TOTO dealers
- Still no voice or app control despite the price — Kohler Numi 2.0 Smart Toilet wins this dimension
The Verdict
Buy the TOTO Neorest NX2 Smart Toilet if hygiene technology is a top-three remodel priority and the budget genuinely supports it — the SHE score of 8.9 is not an accident. For most households, the TOTO Neorest AS Integrated Smart Toilet gets you 92% of the hygiene tech at 25% of the price. If you want the toilet to talk to Alexa, the NX2 won't — switch to the Kohler Numi 2.0 Smart Toilet.

Kohler Veil Intelligent Toilet — Best Mid-Range Integrated
Kohler Veil Intelligent Toilet
(Current Price, subject to change)
The Kohler Veil Intelligent Toilet is Kohler's Numi-without-the-smart-home-tax play. You get Kohler's modernist one-piece elongated design, a full bidet with warm-air dryer and heated seat, auto open/close lid, and a wireless remote — for $5,999 instead of $12,999. What you give up is everything smart-home: no Alexa, no Konnect, no app, no Bluetooth speakers, no ambient lighting. If those features weren't your motivation anyway, the Veil is the better value in the Kohler lineup.
On the SHE Hygiene Automation Score the Kohler Veil Intelligent Toilet comes in at 6.7 — a real gap versus the TOTO Neorest RS Smart Toilet (8.1) at a similar-ish price point. The gap is driven by the self-cleaning dimension: the Veil has no EWATER+ equivalent, no UV, and a warm-water nozzle rinse only (rubric anchor 5.5). If pure hygiene tech is the decision, the TOTO Neorest RS Smart Toilet at $4,476 wins. If modern Kohler design is the decision — minimalist one-piece silhouette, lid geometry — the Veil wins.
Reviewer reports on earlier Veil production runs flagged electronic-component issues; the 2025-2026 revisions have improved, and Kohler's big-box service network resolves repairs faster than TOTO's dealer-only channel.
What We Love
- Modernist one-piece elongated design — the lowest-profile silhouette in Kohler's intelligent lineup
- Full bidet function with warm-air dryer — rear + feminine wash, adjustable temp/pressure
- Automatic open/close lid with LED night light — the core smart-toilet UX without the smart-home layer
- Dual 1.28 / 0.8 GPF flush — meets WaterSense and stays quiet
- Kohler big-box service network — faster repair-cycle support than dealer-only brands
What Could Be Better
- No EWATER+/UV self-sanitization — the biggest SHE Hygiene Automation Score gap vs the TOTO tier
- No voice assistant or Kohler Konnect app — stepping down from Kohler Numi 2.0 Smart Toilet means losing all smart-home features
- Seat lacks auto-raise — only the lid opens automatically
- Flush is effective but noisier than TOTO Tornado Flush
The Verdict
Buy the Kohler Veil Intelligent Toilet if you want modern Kohler design and basic smart-toilet features (auto lid, full bidet, night light) without the $7,000 premium the Kohler Numi 2.0 Smart Toilet charges for the smart-home integration. If hygiene tech matters more than design, cross-shop the TOTO Neorest RS Smart Toilet instead — same price tier, better self-cleaning.
Check Price on Amazon →Check current price: Kohler Veil Intelligent Toilet on Amazon
TOTO Neorest RS Smart Toilet — Best Neorest Value
TOTO Neorest RS Smart Toilet
(Current Price, subject to change)
The TOTO Neorest RS Smart Toilet is the entry point to TOTO's Neorest line — same EWATER+, same Tornado Flush, same premist as the TOTO Neorest AS Integrated Smart Toilet, stepped down at the build-finish level and the no-ACTILIGHT level from the NX2. Our SHE Hygiene Automation Score puts the RS at 8.1 — just 0.1 below the AS and well above the Kohler Veil Intelligent Toilet (6.7) at a similar price point.
If you want the Neorest hygiene tech stack — the reason to buy a TOTO instead of a Kohler — this is the cheapest way in. The RS will out-score almost every integrated smart toilet under $5,000 on reviewer hygiene benchmarks, trades only in build-tier polish and exterior finish versus the AS, and costs roughly $1,500 less. Where it loses to the Kohler Veil Intelligent Toilet: the Veil's one-piece silhouette is more contemporary, and the Kohler big-box repair channel is faster than TOTO's dealer-only route.
No voice, no app — same as every non-Numi on this list. TOTO's position is that a toilet should last 15 years and app integrations don't; the dominant reviewer consensus agrees.
What We Love
- EWATER+ self-sanitization — carried down from higher-end Neorest models, not stripped for the price
- Tornado Flush with dual 1.0 / 0.8 GPF — identical flush performance to the TOTO Neorest AS Integrated Smart Toilet
- Premist coating — reduces waste adhesion before every use
- Skirted one-piece design with integrated Washlet — no attachment look, no visible seams
- Lowest-price entry to the full Neorest line
What Could Be Better
- No ACTILIGHT UV — reserved for the NX2
- Remote-only control (no side panel)
- Visible trim accents may feel dated to minimalist-leaning buyers
- No app or voice — if you need Alexa, Kohler Numi 2.0 Smart Toilet is the only option
The Verdict
Buy the TOTO Neorest RS Smart Toilet if you want TOTO hygiene tech at the lowest price point in the Neorest line — EWATER+ plus Tornado Flush plus premist is the core Neorest stack and it's all here. If you want the NX2's ACTILIGHT UV, step up. If you want the AS's build-tier polish, step across. If you're under $2,000, go to the Bio Bidet Discovery DLX Smart Toilet or a bidet seat attachment.

Bio Bidet Discovery DLX Smart Toilet — Best Entry-Level Integrated
Bio Bidet Discovery DLX Smart Toilet
(Current Price, subject to change)
The Bio Bidet Discovery DLX Smart Toilet is the lowest-price true integrated smart toilet we recommend. At $1,699 you get a one-piece elongated bowl with auto open/close, auto flush, heated seat, warm-water bidet, and a warm-air dryer — most of the functional UX of a $5,000 Kohler Veil Intelligent Toilet at a third of the price. The SHE Hygiene Automation Score of 6.3 reflects the tradeoff: no EWATER+, no UV, plastic nozzle instead of stainless, and a shorter brand track record than TOTO or Kohler.
What the DLX gives you that a bidet seat attachment on a standard toilet doesn't: the one-piece integrated aesthetic. No visible seat attachment, no power cord running to the wall, no hose behind the tank. If that visual matters — guest bathroom, open-concept en suite, anywhere the toilet is on display — the DLX clears a bar that a $600 bidet seat on an $800 base toilet cannot.
If the aesthetic doesn't matter, our smart bidet toilet seats guide is where the value math gets interesting. A TOTO Washlet C5 on a TOTO Drake II comes in under $1,200 combined with better TOTO hygiene engineering than the DLX ships — at the cost of a visible attachment seam.
What We Love
- Lowest-price true integrated smart toilet — $1,699 for one-piece aesthetics
- Full smart-toilet feature set — auto open/close, auto flush, heated seat, warm-air dryer, warm water
- Warm water on demand instead of reservoir heating — never runs out mid-cycle
- Dual 1.28 / 0.8 GPF — WaterSense-qualified
- One-piece elongated bowl — modern low-profile design
What Could Be Better
- No EWATER+/UV self-sanitization tech equivalent
- Brand reliability track record shorter than TOTO or Kohler
- Plastic nozzle rather than stainless steel
- Replacement parts availability varies by region
The Verdict
Buy the Bio Bidet Discovery DLX Smart Toilet if integrated one-piece aesthetics matter and $1,699 is your ceiling — you'll get the core smart-toilet UX at the entry price. If the visual integrated look is not a hard requirement, a TOTO Washlet C5 bidet seat on a standard TOTO base delivers better hygiene engineering for less money.

How We Score: SHE Hygiene Automation Score
What it measures: How well a smart toilet or bidet automates the hygiene routine — from self-cleaning and wash performance to TP reduction, smart-home integration, and long-term reliability.
Formula: SHE Hygiene Automation Score = (Self-Cleaning Tech × 0.30) + (Wash Performance × 0.25) + (TP Reduction × 0.20) + (Smart Integration × 0.15) + (Build Quality × 0.10)
Scale: 0–10, higher is better Data sources: Manufacturer spec sheets, aggregated expert reviews (KBAuthority, CNN Underscored, Pursuitist, BidetKing), consensus-data.ts reviewer aggregation.

Best Smart-Home Integration — native Alexa, Kohler Konnect app, Bluetooth speakers, backup battery flush
Best Overall — EWATER+ + Tornado Flush at the integrated price point most remodel budgets actually hit
Best Neorest Value — EWATER+ + Tornado Flush + premist; lowest-price entry to the Neorest line
Best Mid-Range Integrated — modernist Kohler design without the Numi smart-home tax

SmartHomeExplorer editorial analysis. Formula: Self-Cleaning Tech (30%) + Wash Performance (25%) + TP Reduction (20%) + Smart Integration (15%) + Build Quality (10%) (April 2026). Data: KBAuthority, CNN Underscored, Pursuitist, BidetKing, manufacturer spec sheets.
This score was developed for our best smart bidet toilet seats guide and extends here to integrated smart toilets on the same 0–10 scale. Why the "Best Overall" pick is the TOTO Neorest AS Integrated Smart Toilet (8.2) and not the higher-scoring TOTO Neorest NX2 Smart Toilet (8.9): the NX2's extra hygiene points come from a price band (around $26,000) that sits outside where typical luxury-bathroom budgets land. "Best Overall" weights accessibility alongside score — the same way our bidet seats spoke picked the TOTO Washlet C5 over the higher-scoring BB-2000 Bliss.
Smart Toilet vs Bidet Seat: How to Choose
The split between an integrated smart toilet ($1,700-$26,000) and a smart bidet seat attachment ($200-$650) is mostly about three decisions, not one.
Budget. A TOTO Washlet C5 bidet seat on your existing toilet runs $550. A Bio Bidet Discovery DLX Smart Toilet integrated unit runs $1,699. A Kohler Numi 2.0 Smart Toilet runs $12,999. If budget is the constraint, the bidet seat route wins — same wash performance, same heated seat, same warm-air dryer, fraction of the cost. The integrated-toilet premium buys aesthetics and (at the top end) hygiene-tech you can't attach.
Aesthetics. An attachment seat has a visible seam between seat and bowl, a power cord, and a water line running to the tank. Integrated toilets conceal all of that in a one-piece silhouette. If the toilet is in a guest bathroom, on an open-concept en suite, or anywhere it's on display, the integrated form factor matters. If it's in a primary bath nobody sees, the seam doesn't.
Hygiene tech. TOTO EWATER+ and ACTILIGHT UV are only available on integrated Neorest units — they don't come on the attachment Washlets. If self-sanitizing bowl technology is the priority, you're shopping integrated. Our bidet seats guide covers the $200-$650 tier; this hub covers $1,700+. There's deliberately no overlap in our top picks.
Installation, Electrical, and Plumbing
Every integrated smart toilet on this list needs a 120V GFCI outlet within 36 inches of the toilet. Most older bathrooms don't have one — budget $150-$300 for an electrician to add it, more if the circuit has to be pulled from a distant panel.
Plumbing labor runs $80-$200/hr and integrated smart toilet installs average $1,073-$2,054 total per 2026 Angi data, with higher numbers on one-piece units that require reinforced subfloor (the Kohler Numi 2.0 Smart Toilet is the most commonly flagged here). Bidet seat attachments — covered in our bidet seats spoke — install in 20-30 minutes by most homeowners and don't need an electrician if the outlet is already present.
Water supply: Most units hook into the existing toilet supply line. Some TOTO Neorest configurations request a dedicated cold feed to the Washlet tank — your plumber will flag this during rough-in. No unit on this list requires a hot-water feed.
DIY vs pro: Integrated units — hire a plumber with bidet-install experience. Bidet seat attachments — most homeowners handle the swap themselves, no special tools. If the outlet isn't there, always hire the electrician — the cost of doing that wrong is worse than the cost of doing it right.
When NOT to Buy a Smart Toilet
A $5,000+ integrated smart toilet is hard to justify when the toilet lives in a bathroom nobody sees, when the household is renting and can't take the fixture with them, or when there's no 120V GFCI outlet within 36 inches and the panel run makes the added electrical cost larger than a bidet-seat upgrade would be. The $200-$650 bidet seat attachment route delivers most of the wash-and-dry UX on an existing toilet — the integrated-unit premium is aesthetics, hygiene-tech stacking, and long-term resale, not core function. If any of those three don't apply, the seat attachment is the right call.
Frequently Asked Questions
Is a smart toilet worth it in 2026?
For households doing a bathroom remodel where the toilet is on display and the budget supports $2,000+, integrated smart toilets deliver real UX gains — self-sanitization, auto-flush, bidet wash, heated seat. For the rest of the market, a $200-$650 bidet seat attachment on an existing toilet captures 80% of the value at a fraction of the price. Payback via TP reduction alone is 2-4 years for seats, 15+ years for integrated units.
Do smart toilets need a dedicated electrical outlet?
Yes. All six integrated smart toilets in this guide require a 120V GFCI outlet within 36 inches of the toilet base. If your bathroom doesn't have one, budget $150-$300 for an electrician. This is usually the single most-missed cost in a smart-toilet remodel line item.
What happens to a smart toilet during a power outage?
Most models lose auto-flush, auto-lid, and bidet wash during a power outage but retain manual-flush capability via a backup button or lever. The Kohler Numi 2.0 Smart Toilet is the only model on this list with an emergency backup battery that keeps the flush function active during an outage — none of the TOTO Neorest models or the Kohler Veil Intelligent Toilet have battery backup.
How much does it cost to install a smart toilet?
Per 2026 Angi data, integrated smart toilet installation averages $1,073-$2,054 including labor. Plumber rates run $80-$200/hr. Budget an additional $150-$300 for electrical if no GFCI outlet is within 36 inches. Bidet seat attachments cost $400-$1,500 including the attachment itself and roughly 20-30 minutes of DIY labor — or the same plumber hourly rate if you hire out.
TOTO vs Kohler: which smart toilet brand is better?
Both brands are top-tier. TOTO leads on self-cleaning and hygiene technology — EWATER+ and ACTILIGHT UV are unique to the Neorest line and score higher in reviewer hygiene benchmarks. Kohler leads on smart-home integration — the Kohler Numi 2.0 Smart Toilet is the only integrated toilet with native Alexa and a manufacturer app. Pick on which dimension matters most to your remodel.
How long do smart toilets last?
TOTO and Kohler flagship integrated units are engineered for 10-15 year ownership horizons. Replacement parts are available through dealer networks with 7-14 day lead times on most components. Bio Bidet's track record is shorter — the Bio Bidet Discovery DLX Smart Toilet is a reasonable 5-8 year unit based on early-generation reliability data.
Smart toilet vs bidet seat attachment — which should I buy?
Bidet seat attachment ($200-$650) when budget is the constraint, the existing toilet is in good condition, and the attachment-seam aesthetic is fine. Integrated smart toilet ($1,700-$26,000) when aesthetics matter, when you want self-sanitizing bowl technology like EWATER+ or ACTILIGHT (only on integrated Neorest), or when you're doing a full remodel anyway and the incremental cost is absorbed in the project.
Can you install a smart toilet yourself?
Integrated units: usually no — the combination of water supply, drain alignment, and electrical tie-in makes professional install the safer call. Bidet seat attachments: yes — most homeowners handle the swap in 20-30 minutes with no special tools beyond an adjustable wrench.
