Best Smart Toilets & Bidet Toilet Combos
A smart toilet is the all-in-one version of a bidet. Instead of bolting a fancy seat onto the toilet you already own, you rip out the old toilet entirely and replace it with one unit that has the bowl, the heated seat, the warm-water wash, the dryer, and the controls all built in. Everything is engineered to work together, the wiring is hidden, and there is no add-on seat sitting on top making things look bulky.
That is the real fork in the road for most buyers. If you want the cleanest look and a single integrated machine — and you don't mind a bigger spend and a plumber — a smart toilet is the move. If you'd rather keep your current toilet, spend a fraction of the money, and install it yourself in half an hour, a bidet toilet seat does almost everything a smart toilet does. We cover those separately; this page is for people who have decided to replace the whole toilet.
We researched these by synthesizing manufacturer specs, verified owner-review patterns at scale, and analysis from specialist plumbing retailers and independent review sites. We have not done hands-on lab testing, and we say so. Where reviewers flagged consistent reliability or fit problems — good or bad — we report them. Every pick here has real trade-offs worth knowing before you spend, whether that's $700 or $5,000.

TOTO Neorest RH
Key features: Tornado Flush siphon-jet system, dual flush 1.0 / 0.8 GPF (3.8 / 3.0 LPF) · Hands-free auto open/close lid (proximity sensor + remote) and automatic flush with manual backup · Front, rear and soft-rear washes with oscillating + pulsating modes, heated seat (82–97°F), warm-air dryer and O2 deodorizer · EWATER+ electrolyzed-water self-cleaning of bowl and wand, plus PREMIST and CeFiONtect glaze · 120V / 60Hz, ~1,290W, requires a grounded GFCI outlet (about 3.9-ft cord) · One-piece elongated, 12-inch rough-in, ADA chair height (~15.9-in seat); ~27-1/8" D x 15-3/16" W x 21-1/16" H
Pros
- Genuinely self-cleaning: EWATER+ mists the bowl and rinses the wand with electrolyzed water, cutting how often you reach for chemical cleaners
- Powerful, water-thrifty Tornado dual flush at 1.0 / 0.8 GPF that owners say rarely clogs
- Full luxury washlet built in — heated seat, warm-water wash, air dryer, deodorizer and auto lid all in one sleek one-piece unit
- TOTO's reputation for reliability and a clean, skirted design that's easy to wipe down
Cons
- Flagship price — typically $4,400 to $5,100, several times the cost of a toilet plus a bolt-on bidet seat
- Requires a nearby grounded GFCI outlet; many bathrooms need an electrician first
- No UV ACTILIGHT sanitizing (that's reserved for the pricier 750H); the RH relies on EWATER+ alone
- Now an older model that TOTO has been phasing toward the newer Neorest RS/LS, so stock and color options can be limited
Who it's for: Buyers building or renovating a primary bath who want a true all-in-one luxury smart toilet — not a budget seat add-on — and value low-maintenance self-cleaning and water efficiency over the absolute lowest price.
Kohler Veil
Key features: Tankless pump-assisted dual flush: 0.8 or 1.28 GPF, WaterSense certified (up to 20% less water) · Hands-free auto open/close lid and automatic flush, plus Quiet-Close lid and LED bowl nightlight · Warm-water bidet with adjustable spray shape, position, pressure and temperature, plus pulsate and oscillate; front and rear wash · Heated seat, warm-air dryer, and automatic deodorizer, all with adjustable settings · Self-cleaning stainless wand using UV light + electrolyzed water (cleans the nozzle, kills up to 99.99% of germs) · Requires a dedicated 120V GFCI circuit; emergency manual flush works up to ~100 times during a power outage
Pros
- One of the best-looking integrated smart toilets on the market — clean skirted one-piece lines and a true tankless profile
- Strong, no-clog pump-assisted flush that rarely needs a second push
- Loaded feature set (heated seat, warm-water wash, dryer, deodorizer, nightlight) at a price below the comparable TOTO Neorest
- UV + electrolyzed-water self-cleaning wand is a hygiene step most rivals don't match
Cons
- Premium price — this is a four-figure fixture, not a bidet-seat upgrade
- Flush is powerful but loud; owners warn against putting it in a master bath next to a sleeping partner
- Needs a dedicated GFCI outlet and strong water flow, so installation often means hiring a plumber and sometimes an electrician
- Reports of electronics (seat heat, smart controller) failing after a couple of years, against only a 3-year warranty
Who it's for: Homeowners renovating a bathroom who want a true all-in-one luxury toilet — heated seat, bidet, dryer, auto lid and flush — and care as much about how it looks as how it works. Best for buyers with a dedicated outlet nearby (or willing to add one) and a budget for a permanent fixture rather than a clip-on bidet seat.
WOODBRIDGE B0970S
Key features: Dual-flush siphonic: 1.6 GPF / 1.0 GPF (1.28 GPF average), tankless booster-pump design · Full bidet wash suite: posterior, feminine, and pulsating modes with adjustable position, pressure, and water temperature · Heated seat + heated water + warm-air dryer + automatic deodorizer + LED night light · Auto/foot-sensor/remote flush; self-cleaning nozzle; power-outage manual flush (battery sold separately) · ADA comfort height (~17.3 in seat), elongated one-piece, standard 12-in rough-in · Electrical: 110–120V, ~1200–1400W, requires a GFCI outlet
Pros
- Packs heated seat, heated-water bidet, dryer, deodorizer, and auto flush at well under half the price of comparable Toto or Kohler smart toilets
- Tankless one-piece design looks sleek and is easy to wipe down with no tank-to-bowl crevices
- Touchless options galore: foot sensor, remote, and off-seat auto flush
- ADA comfort height plus a night light make it friendly for seniors and middle-of-the-night trips
Cons
- No auto open/close lid at this price point (you raise the lid yourself)
- Only a 1-year limited warranty, short for an electronic toilet costing this much
- Requires a dedicated GFCI outlet nearby, which often means hiring an electrician
- A minority of owners report electronics or sensor glitches showing up within the first year
Who it's for: Homeowners who want a true all-in-one smart bidet toilet, not just a clip-on seat, but refuse to pay $4,000+ for a Toto Neorest or Kohler Numi. It is the value pick for anyone upgrading a single bathroom who wants heated, hands-free comfort without luxury-tier spend.
OVE Decors Felix
Key features: Dual flush, WaterSense-rated (about 1.06/1.59 GPF on the tank model; 1.28 GPF on tankless versions) — strong waste removal at low water use · Heated, soft-close elongated seat with 4 temperature settings · Warm-water bidet wash with adjustable temperature and pressure, plus warm-air dryer · Hands-free automatic flush and automatic deodorizing · LED night light, ECO power-saving mode, built-in side control panel plus a wireless remote · Requires a nearby GFCI outlet (dedicated ~1800W circuit); no separate hot-water line needed
Pros
- Full integrated smart-toilet feature set — warm-water wash, heated seat, dryer, deodorizer, and auto flush — at a price well below TOTO or Kohler equivalents
- Hands-free operation: it senses you stand up, then runs a self-clean rinse and flushes automatically
- Heats its own water instantly, so there's no separate hot-water line to run
- Clean, modern look with a soft-close seat and a helpful LED night light
Cons
- Several owners report plastic seat hinges and lid pieces cracking or coming apart over time
- Some units develop a slow drip or fill-valve leak that's tricky to fully stop
- Fewer refinements (and shorter track record) than premium brands like TOTO; OVE's customer service draws frequent complaints
- Like all electric smart toilets, it stops washing/drying during a power outage and depends on a GFCI outlet you may need to add
Who it's for: Homeowners who want the full luxury-toilet experience — warm water, heated seat, dryer, and a touchless flush — without paying $3,000-plus for a top-tier brand. It's a strong fit for a first smart toilet, a guest bath upgrade, or anyone replacing an aging seat-and-tank combo who'd rather buy one finished, good-looking unit than bolt a bidet seat onto an old bowl.
Swiss Madison Avancer
Key features: Tankless one-piece, dual Vortex flush 1.1/1.6 GPF (water-sipping, WaterSense-class dual flush) · Touchless flushing: auto off-seat flush, foot-sensor flush, remote, plus 9V battery backup flush during outages · Integrated bidet: front/rear wash, adjustable warm water temperature, pressure and spray position, plus warm-air dryer · Heated seat (adjustable), self-cleaning nozzle, and built-in LED night light · Requires a grounded GFCI outlet (standard 120V); no full battery-only operation · Dimensions ~27-3/16"D x 16-3/4"W x 18-3/4"H, 12" rough-in, ~15-9/16" seat height; soft-close lid
Pros
- Integrated smart-toilet features (heated seat, warm-water bidet, dryer, night light, touchless flush) at hundreds less than premium brands
- Clean tankless one-piece silhouette that looks high-end and is easier to wipe down
- Genuinely warm seat and instant-on warm water, not a tepid reservoir
- Multiple flush options including hands-free auto and foot sensor, with a battery backup for power outages
Cons
- Warm-air dryer is widely called slow and weak — most owners still reach for paper
- Needs a nearby GFCI outlet; if you don't have one, budget for an electrician
- Big elongated footprint won't suit tight or small bathrooms
- Newer brand without the decades-long reliability track record of Toto or Kohler
Who it's for: Style-conscious buyers who want a fully integrated smart toilet — heated seat, warm-water bidet, touchless flush, night light — without paying $4,000+ for a Toto Washlet or Kohler Numi. Best for a 12-inch rough-in bathroom that already has (or can easily add) a grounded outlet near the toilet.
HOROW T05
Key features: Pump-assisted 1.03 GPF flush with a concealed built-in tank and booster pump (works in low-pressure homes) · Auto open/close lid plus auto, foot-touch, remote, and manual flush · Heated seat (4 levels), warm-water bidet wash, warm-air dryer (4 levels), and automatic deodorizer · Ceramic instant water heating — endless warm water, no holding tank to run cold · Self-cleaning nozzle with UV/anti-bacterial sterilization and a night light · 12-inch rough-in; requires a grounded GFCI outlet; optional battery pack for power-outage flushing
Pros
- Built-in booster pump delivers a strong, consistent flush even in older homes with weak water pressure
- Packs heated seat, warm-water bidet, dryer, deodorizer, auto lid, and self-clean into a sub-$1,000 price
- Instant ceramic heating means warm water and a warm seat never run out mid-use
- Compact 27-inch depth and standard 12-inch rough-in fit most American bathrooms
Cons
- No battery backup for the flush included — power-outage flushing needs an add-on battery pack sold separately
- Remote has hidden secondary functions that aren't labeled, so there's a learning curve
- Heated seat can show discoloration over time per some long-term owners
- Short warranty (12-month limited on retail purchases) for a feature-heavy electronic toilet
Who it's for: Homeowners who want a full luxury smart-toilet experience — heated seat, warm-water bidet, dryer, auto lid — without the Toto or Kohler price tag, especially anyone fighting weak water pressure or older plumbing where a standard toilet struggles to clear the bowl.
What matters when choosing a bidet seat
- Flush power and reliability. An integrated toilet still has to do the basic job: clear the bowl in one flush, every time. Look for a MaP (Maximum Performance) score of 600 grams or higher, which is plenty for a household, and a dual-flush design that lets you use less water for liquid waste. Tankless luxury models like the TOTO Neorest use a powered, pump-assisted flush instead of a gravity tank, while budget models such as the HOROW T05 hide a small tank and a booster pump inside the unit so they still flush hard in low-pressure homes. Either approach works — what you don't want is a unit owners report needing to double-flush.
- Automatic features. This is the convenience tier that separates a true smart toilet from a glorified bidet. The best units open the lid as you walk up, raise the seat with a separate sensor for men, and flush automatically when you stand. Motion and proximity sensors drive all of this. Higher-end models (TOTO Neorest, Kohler Veil) get full auto open/close and auto flush; budget models (WOODBRIDGE, OVE Felix, Swiss Madison) usually offer auto flush and a foot-sensor or touchless flush, but may need a button press to open the lid. Decide how hands-free you actually want to be — every step up adds cost.
- Bidet wash quality and comfort. The wash is the whole point. You want on-demand warm water that doesn't run cold mid-rinse, a heated seat you can set to your liking, adjustable pressure and nozzle position, and separate front (feminine) and rear wash modes. A warm-air dryer and an air deodorizer are the comfort upgrades that make a unit feel premium. Luxury models heat water instantly and offer oscillating and pulsing massage modes; budget models cover the core warm wash, heated seat, and dryer well but with fewer fine-tuning options. All of these have those basics — the gap is in how dialed-in the experience gets.
- Self-cleaning and hygiene. Because the bowl and the wash wand live in the same unit, the best smart toilets clean themselves between uses. TOTO's EWATER+ electrolyzes ordinary tap water into a mild sanitizer and mists the bowl and wand automatically, and PREMIST wets the bowl before use so less sticks. Other brands use UV light or a self-rinsing wand. The wand on every unit here retracts and rinses itself. None of this replaces normal cleaning, but it dramatically cuts how often you scrub. The more you spend, the more thorough the automated hygiene gets.
- Installation and electrical. An integrated toilet is a full replacement, so it sits on a standard 12-inch rough-in (the distance from the wall to the floor bolts — measure yours first) and connects to your existing water and drain. The one thing every smart toilet needs that a basic toilet doesn't is power: a 120V GFCI outlet within a few feet of the toilet. If you don't have one, an electrician can add it for roughly $100–$200. The toilet swap itself is plumber-friendly but heavier and more involved than installing a bidet seat. Budget a half-day and, for most people, a pro.
- Price tiers. There are two clear worlds here. Budget integrated toilets — WOODBRIDGE, HOROW, OVE Felix, Swiss Madison — run roughly $700–$1,100 and deliver the heated seat, warm-water wash, dryer, and auto/touchless flush that cover 90% of what most people want. Luxury units — TOTO Neorest, Kohler Veil — run $3,500–$6,000 and add instant tankless heating, the most complete self-cleaning systems, the slimmest tankless designs, and the smoothest full-auto operation. The honest question is whether the top-tier hygiene tech and finish are worth four to six times the price for you. For many buyers, the budget tier is the smarter spend.
How we ranked these
We ranked these integrated smart toilets on how well they deliver the four things that actually matter once the whole toilet is being replaced: a reliable, strong flush; a consistent warm-water wash with a comfortable heated seat; genuine self-cleaning and hygiene automation; and convenience features that work day in and day out. Price mattered only as a measure of value — we did not rank a $5,000 toilet above a $900 one unless the extra spend bought a meaningfully better experience, which is why budget standouts share top spots with the Japanese flagships. We weighed verified owner-review patterns heavily and flagged any model with recurring reliability or fit complaints, even when the spec sheet looked strong. We excluded bidet toilet seats entirely — those install on your existing toilet and are covered in a separate guide for buyers who don't want to replace the whole fixture.
Frequently asked questions
Do I need an electrician or a new outlet for a smart toilet?
You need a 120V GFCI outlet within a few feet of the toilet, because every integrated smart toilet runs on electricity to power the heated seat, warm-water wash, dryer, and sensors. Many bathrooms already have a GFCI outlet near the vanity, but it is often not close enough to the toilet. If there's no suitable outlet within reach, you'll need an electrician to add one, which typically runs $100–$200. That is a one-time job, and it's the main thing people forget to check before buying.
Are smart toilets hard to install?
Installing the toilet itself is similar to swapping any standard toilet — it sits on a normal 12-inch rough-in and connects to your existing water and drain — but an integrated unit is heavier and has the electrical connection to deal with, so most people hire a plumber. Budget a half-day. The harder part is usually the prep: confirming your rough-in measurement, making sure the GFCI outlet is in place, and clearing space to maneuver the unit. This is genuinely more involved than a bidet seat, which most homeowners install themselves in under 30 minutes.
Are smart toilets reliable long-term?
The established brands are. TOTO and Kohler have been building electronic toilets for years and carry the reliability records and parts support to match, which is part of what you pay for at the luxury tier. The budget brands — WOODBRIDGE, HOROW, OVE, Swiss Madison — generally hold up well, but owner reviews show more variation in things like control panels, sensors, and customer service. Across every brand, the moving electronic parts (the wash wand, the dryer fan, the sensors) are the components most likely to need service over a decade. Check the warranty length and whether US-based support is available before you buy.
Smart toilet vs bidet seat — which should I buy?
Buy a smart toilet if you want a single integrated unit with the cleanest look, you're already replacing the toilet or doing a remodel, and you don't mind the higher cost and a plumber. Buy a bidet seat if you like your current toilet, want to spend a fraction of the money, and want to install it yourself in about half an hour. A good bidet seat delivers nearly the same warm wash, heated seat, dryer, and hygiene features as an integrated toilet — the smart toilet's real advantages are the seamless built-in look, often smoother full-auto operation, and not having two pieces. For most people the seat is the better value; the integrated toilet is the better experience if budget and aesthetics allow.
What happens to a smart toilet in a power outage?
You can still flush. Every model here has a manual or mechanical flush backup, so even with the power out the toilet works as a basic toilet — you just lose the electronic features like the heated seat, warm-water wash, dryer, and auto open/close until power returns. On some models the manual flush is a button or lever on the unit; on others it's a cap you press on top of the tank or a cable. Check your specific model's manual so you know where the override is before you ever need it. No model on this list leaves you stranded without a flush.
