An automatic flush toilet does one simple job: it senses you and handles the flush for you, so nobody has to touch a handle again. But the models on this list are not the same machine in a different wrapper. Some open the lid as you walk in and flush as you leave. Some add a bidet wash, a heated seat, a warm-air dryer, and a foam layer that stops splashes before they happen. The catch most buyers miss is the plumbing behind the wall — your rough-in distance and a nearby power outlet decide which of these will actually fit your bathroom.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You will see how flush power is scored, why a built-in tank beats your home’s water pressure, and which seat height saves your knees. Every pick below is measured against the same standard so you can find the best automatic flush toilets for your bathroom without guessing.
Our Picks at a Glance
How To Choose The Best Automatic Flush Toilets
Three measurements decide almost everything before you read a single feature list. Get these wrong and the best-reviewed toilet on this page still will not fit your floor.
Measure Your Rough-In Before Anything Else
Rough-in is the distance from the finished back wall to the center of the drain hole in the floor, and these toilets are built around a standard 12-inch rough-in. Measure yours with the old toilet out, not around it. A toilet built for 12 inches sitting on a 10-inch rough-in leaves a gap at the wall that no amount of caulk hides.
Find Out Whether You Have Low Water Pressure
Many automatic flush toilets skip the tank and rely on your home’s pressure to push waste away. If your pressure is weak, that is the wrong machine. A built-in tank or a booster pump with a MaP (Maximum Performance) score of 1000 grams flushes the same regardless of pressure. This is the number serious buyers check first.
Check That You Have a Power Outlet Nearby
These are electric toilets. They need a live outlet within reach of the power cord, and most cords run roughly 12 to 47 inches. A heated seat, warm-water wash, and a dryer all draw power, so an outlet behind the toilet or on the side wall is what you want. An extension cord across a wet bathroom floor is not the answer.
Decide Which Hands-Free Features You Actually Want
Every pick here flushes automatically, but the extras split them apart. Auto open and close lid, a foot sensor that lifts the seat without bending, a heated seat, a bidet wash, a warm-air dryer, a foam shield, and a deodorizer are the common upgrades. Know which two or three you care about, because paying for the rest is wasted money.

In‑Depth Reviews
1. WOODBRIDGE Smart Toilet with 1000g MaP Flush Score & Foam Shield (B0930S)
Our pick — over 4.5★ from 250+ verified ratings; the strongest balance of quality and price.
The do-everything smart toilet that still keeps a 1000-gram flush score.
A flush performance score of 1000 grams MaP is the headline here, and it means the toilet clears the bowl in one go while using less water than an older unit. That is backed by a built-in tank, so weak water pressure in your home is not a problem. The dual flush lets you pick 1.6 GPF for a full flush or 1.1 GPF for a half flush, which trims water use without asking you to sacrifice anything.
What wins people over is the build and the day-to-day function, and that reads clearly across the reviews. The lid opens as you approach and closes and flushes after you leave, and there is a foot sensor for touch-free seat and lid control. A soft foam layer goes down before each use to cut splashes, odors, and flush noise, and a catalyst-free deodorizing system works on odor molecules in the air. The moving dryer runs back and forth at low, medium, or high speed, so you can skip paper more often.
Here is the honest trade-off: this is a heavy one-piece porcelain unit at 112 pounds, and it needs two people to set in place. It is also the larger footprint of the two WOODBRIDGE picks — 27.63″D x 16.53″W x 19.75″H against the GT090’s 27″D x 15.4″W x 19.1″H. The 17-3/8″ floor-to-seat height is aimed at buyers with knee trouble, since standing up is easier from that height. The crowd favorite with the strongest rating here, it sits at 4.7 stars across 290+ ratings.
1000g MaP flush
- 1000g MaP score flushes cleanly in a single pass, even with low home water pressure, thanks to the built-in tank.
- Foam shield plus a catalyst-free deodorizer cut splashes, stains, and smell between cleanings.
- The moving dryer runs low, medium, or high, so you rely on paper far less.
- Power-off flush keeps it working through an outage using the side button.
- 17-3/8″ ADA height makes sitting down and standing up noticeably easier on stiff knees.
smart features add cost
- At 112 pounds it is the heaviest indoor pick here, so plan on a second pair of hands for the lift.
- The footprint is wider than its GT090 sibling, so measure your available floor space first.
- No auto seat open on the P-model cousin — the woodbridge foot sensor handles it instead.
strong flush pick: you want the most complete automatic flush toilet on the list, with foam, a moving dryer, and a flush score that does not depend on your plumbing.
budget buyers: you need the lightest or narrowest body, or you want a lower entry point into hands-free flushing.
2. TDH Luxury Smart Toilet with Bidet Built In, Instant Warm Water Dryer Heated
A big black screen, a vortex flush, and less than half the weight of the top pick.
If you want an oversized LCD that shows real-time water and seat temperature in Fahrenheit, this is the pick. The black display is the standout here, and it works with four adjustable heating levels for the seat and water plus a constant warmth mode. Motion gets the lid and flush handled — the lid works touch-free, and a foot sensor handles the seat and flush so nobody bends or touches anything.
It flushes with a 1.26 GPF vortex system and includes an emergency flush function for power outages. Pre-wetting the bowl keeps it cleaner between uses, and the multi-clean setup gives you rear, feminine, and massage wash modes with a self-cleaning nozzle, five position and pressure levels, and both a remote and a side knob. Night use is quiet, with a gentle night light and a soft-close lid that eliminates the noise and impact.
At 89 pounds it is 23 pounds lighter than the WOODBRIDGE B0930S, which matters most on installation day when you are lifting the unit onto the flange. Its 17-inch ADA height and 12-inch rough-in match the rest of the field. The catch is that flush power draws mixed opinions from owners, so if you have hard-to-clear waste this may not be the one. Note that the standard 12-inch rough-in applies.
instant warm water: you get a lot of display and bidet features for the money, so the real question is whether the 1.26 GPF flush (1.26 gallons per flush, a low-flow rate that saves water) fits your household. Buyers report after a year of use: quality holds, it works as advertised, it saves water, and the look still reads premium — though the dryer vent could push more air.
warm water comfort: you want a large readable temperature display, a 12-inch rough-in fit, and a lighter body than the premium picks.
simple toilet need: you need the most forceful flush possible, since owners are split on flush power here.
3. DeerValley Luxury Smart Toilet with Bidet Built in Bubble Wash
A sleek dual-color one-piece that leads its class on looks alone.
The reason this one stands out in the group is appearance, and it is the most-photographed style of the set. The one-piece body is a modern Japanese silhouette, and the included remote controls the LED display easily. You can choose from three flush modes — exit sensor, foot sensor, or the remote — so you can flush without touching anything at all.
The unique bubble wash is the bidet standout here. It delivers front, rear, and oscillating spray with adjustable water temperature, pressure, and spray position, all run from the wireless remote. An electrically heated seat and a warm-air dryer work alongside an ambient nightlight, and instant warm water means the wash is not cold on the first pass.
A jet-push tankless flush pushes waste through even in a low-pressure home, and it comes with an integrated filter to keep the water supply clean and protect the internal parts. At 78 pounds it is the lightest floor model in this group, which makes the install easier for one careful person. The catch to know: the flush performance and installation process draw mixed feedback from owners, and the lid functionality gets the most notes against it.
spa-like cleaning: buyers who care most about how the bathroom looks and want a 12-inch rough-in, dual-color one-piece with a filter built in.
mainstream brand fans: flush performance is your top priority, or you want a build that skips the plastic seat material.
4. CANEST FC-001P Bidet Toilet, 17″ Chair Height, 1000g MaP Flush, Heated Seat
The low-pressure specialist: its built-in tank and pump flush with zero inlet pressure.
If your house struggles to send water up the pipe, this is the pick. It carries a 1000-gram MaP score and uses a built-in tank with a pump, so it flushes on zero water pressure. The dual flush splits between 1.6 GPF and 1.1 GPF (6 and 4 LPF) to keep water use down while preserving the strong flush.
The FC-001P is the value member of the CANEST line, so it keeps the heated bidet, the warm-air dryer, the self-cleaning nozzle, the foot sensor (a sensor you tap with your foot to flush), and blackout flushing (a manual flush that works when the power is out), but it does not include auto-opening or foot-sensor opening for the lid and seat. Owners single out the 17-inch ADA comfort height as the feature that makes sitting and standing easier. The wireless remote, LED display, night light, and auto deodorization round out the feature set.
One heads-up that comes through in owner feedback: the setup is not always intuitive and the documentation is thin. A few owners had to figure out the pump and water-supply arrangement on their own, though the manufacturer answered questions when they called. If you want the fully hands-free lid operation, the standard FC-001 is the version to look for instead, since the P here trades that away for the lower price.
17 inch chair height: the power users behind the pump are the same people who tend to buy a second one. Owners mention the foot sensor and off-seat auto flush work flawlessly, and the 17-inch comfort height eases strain on knees. It totals 4.9 stars across 30+ ratings — the highest score on this list.
easy sit down: low-water-pressure homes, or anyone who wants a 1000g flush and an ADA-height seat without paying for the auto lid.
dryer required: the lid does not open automatically here, and the included documentation leaves the first setup to some guesswork.
5. WOODBRIDGE Bidet Smart Toilet with Auto Open/Close & Foam Shield (GT090)
The one pick where you can tune how far away the lid wakes up.
Most automatic toilets open the lid at whatever distance the factory chose. This one lets you set the sensor range to 20, 40, 60, 80, or 100cm, so it only reacts when you mean it. You can also switch the sensor function off entirely. The lid opens on approach and closes and flushes after you leave, and the foot sensor handles touch-free lid and seat operation.
What rounds it out beyond the top pick is a built-in fragrance tablet that releases a steady scent. Pulse wash alternates water pressure rhythmically for a massaging clean, and the foam shield system lays down a layer that cuts splashes, stains, odors, and flush noise, with a bottle of foam solution in the box. The self-cleaning curved stainless steel nozzle sprays before and after each use and resists rust. Rear and front moving wash, bowl pre-moistening, adjustable water temperature and pressure, and a heated seat with a digital water-temperature readout for easy adjustment complete the set.
A backup battery box with 10 AA batteries keeps it flushing in an outage, though the batteries are not included. At 77 pounds it is the lightest of the WOODBRIDGE picks, sitting below the 112-pound B0930S and the 116-pound EPLO U8MAX. The 17.4-inch chair height and 12-inch rough-in keep it install-friendly. Expect about an hour of install time, and plan on a helper, since it still ships as one heavy piece.
auto open close lid: quality is the most-praised aspect by a wide margin, and it is the smaller, quieter cabin-mate to the flagship above. One owner upgraded from an older WOODBRIDGE model and reported this one beat a unit they had already loved.
hands free users: small bathrooms where the lid firing off from the hallway would drive you mad, thanks to the tunable 20-100cm sensor range.
manual lid fans: you want the extra drying-room space and heavier build of the flagship, since the GT090 is the lighter unit.
6. EPLO Smart Toilet Built in Tank Auto Open Bidet with Foam Shield — iX7 PRO
A 1000-gram flush with a booster pump for houses where pressure is not perfect.
The iX7-PRO pairs a built-in tank with a booster pump, so the 1000-gram MaP flush holds up in a home with weak water supply. The siphonic jet flushing technology drives waste through quietly, and the practical result is a strong clean without depending on your plumbing. Owners running low pressure at home report it outperformed a previous tankless unit that was inconsistent.
Beyond the flush, this is a fully loaded smart toilet: heated seat, high-speed warm-air dryer, instant warm water, automatic flushing, kick flushing, soft-close lid, night light, warm wash, and an LED temperature display. The auto open/close lid can be switched off, and when it is off you can still open and close by foot kick or remote. Flushing comes four ways — off-seat auto, side button, foot kick, or remote — and it can flush during a blackout.
Independent testing is where this model stands apart from most of the field: it is CUPC and ETL listed, registered in the CEC database, and carries a Japanese SIAA certification. Its 17-inch ADA seat height and 12-inch rough-in match the group standard. The one negative that keeps surfacing, even from owners who love the toilet, is volume — it runs loud. Several note they would not pay over the odds for a quieter unit, so the trade-off may not matter to you.
no tank worries: you want certified flush performance and a pump that fights back against a weak water supply.
low maintenance want: you value a quiet bathroom, since homeowners repeatedly flag this model as the loud one.
7. EPLO Smart Toilet Bidet, 1000G MaP Flush, Foam Shield, ADA Chair Height U8MAX
One-flush 1000-gram power with a foam shield and a quieter, smarter dryer.
This is a flagship build with a 1000-gram MaP score, and it clears waste in a single flush while keeping the noise down. The moving air dryer adjusts temperature, wind speed, and position, so you tend to reach for paper less. Humidity is handled: a foam shield lays down a protective layer that fights splashback and keeps waste from sticking to the bowl.
Comfort is where this shines. Its 17.41-inch floor-to-seat height meets ADA Standard 117.1, easing knee and back strain for taller and older users. Auto open on approach and auto close and flush on exit work with a built-in foot sensor for the lid, seat, and flush. Front, rear, and oscillating wash modes all run with adjustable water pressure, spray position, and temperature. A four-season temperature system auto-adjusts the heated seat, warm water, and dryer to the ambient air, alongside a nightlight and a dual LED display.
Dual flush splits between 1.6 GPF full and 1.1 GPF half. The 27.63-inch depth and 16.14-inch width are the widest footprint of the EPLO group as well.
foam shield odor: the EPLO name carries with it a reputation for fanatical support — customers note the kind of service that sends a replacement remote a year in, out of warranty. Build quality is the most-praised aspect by a long margin, followed by function and value. It has held 4.7 stars across 250+ ratings.
odor control seeker: buyers who want heavy build quality, a moving dryer, and the tallest ADA-friendly seat in this list.
basic flush need: your bathroom is tight and you need the smaller footprint or the lighter weight of a competitor.
8. Casta Diva CD-U010Max Smart Toilet with Bidet Built in, Auto Open Close
A 45dB whisper flush with four seasons of built-in lighting.
Noise is the specification that matters most here. The 45dB flush is about as quiet as a running conversation, which keeps the whole house asleep on a midnight trip. What heightens that is the lighting: a cascading waterfall band with four seasonal hues — green, blue, orange, and white — plus a soft-glow nightlight for navigating the dark.
Cleaning is engineered into the mechanics. An electrolyzed water mist sprays across the ceramic bowl during cleaning for 360° coverage, and it forms a hydrophilic protective layer that keeps residue from sticking. A dense foam barrier descends on sitting, cutting splashes and odors and cushioning waste impact, and it can be mixed with most liquid soaps. Warm water is instant for front, rear, and oscillating wash, and the self-cleaning nozzle handles itself before and after each use.
A 1000-gram MaP-certified flush runs off a built-in tank, so low-pressure homes and high-rise apartments need no extra retrofit. If the power dies, blackout flush still works. The 17-3/8-inch ADA seat height eases knee strain for seniors, expectant mothers, and recovering patients. The one note to know: the temperature function ships off by default, so you will need to switch it on per the manual, and it adjusts across four preset modes.
feature maximalist: buyers who want a nearly silent flush and a bathroom that glows — the 45dB operation and four-hue lighting are one-of-a-kind here.
value shoppers: the comfort features ship switched off, so plan a few minutes to enable them per the manual.
9. Casta Diva K030 Smart Toilet With Bidet Built in Auto Open 1000g MaP Flush
The one smart toilet you never have to aim at — it just reacts when you sit.
The seat sensor here is the unique trick. Instead of hunting for an activation point, the bidet seat triggers whenever anyone over 28.66 pounds sits down, which makes it easy for adults and gentle for kids. A blue-light foot sensor controls the seat, lid, and flush, so full hands-free use is possible without any buttons. The lid opens on approach and closes and flushes when you leave.
Raw flush power does not take a backseat. It has a 1000-gram MaP score with a built-in tank, no water-pressure restriction, and a siphonic flush that runs quietly at 45dB. The foam shield drops a thick barrier on sitting to block splashes, trap odors, and resist sticking to the bowl, and the recipe is simple: mix dish soap 1:1 with water. The self-cleaning nozzle primes before each use, then you get rear, front, and oscillating warm-water massage modes with 0.1s instant warm water.
An intelligent temperature system adjusts the seat and water across five presets based on ambient temperature, though it defaults to off on first use and needs to be switched on per the manual. The wider five-speed heated seat, warm-air dryer, dual flush, night light, auto deodorizer, and digital display round out the roster. The installation is a two-hour job that needs an outlet nearby — the same starting requirement as every pick above.
auto open lid: the recommendation rate is high across the reviews, and performance and value score close behind it. Reviewers point out the automatic flush does the job most of the time, with one noting the drying function feels gentle yet effective.
convenience seeker: you want a warm-water bidet, a 1000g single-pass flush, and a seat that senses you without any aiming.
brand loyalist: temperature adjustment starts switched off, so the first setup needs a manual check.
Understanding the Specs
MaP Flush Score
MaP stands for Maximum Performance, and it is a test score in grams of how much waste a toilet clears in a single flush. A 1000-gram score is the top of the scale these smart toilets quote, and it tells you the unit should handle a full load in one pass rather than two. That matters because a second flush wastes water and time. If a toilet lists a 1000g MaP score, that is the number serious buyers weigh against every other feature on the box.
GPF and Dual Flush
GPF stands for gallons per flush, the water volume each flush uses. Many of these toilets give you two choices — often 1.6 GPF for a full flush and 1.1 GPF for a half flush — so you can match the water to the job. It is a small lever with a big effect: the half-flush setting uses less water every time you choose it. A built-in tank or pump lets these units deliver that flush strength even when your home’s water pressure is low.

Final Thoughts: The Verdict
The overall winner among the best automatic flush toilets goes to the WOODBRIDGE B0930S because it pairs a 1000-gram MaP flush (a test that measures how much waste a toilet clears in one flush) with a built-in tank, a foam shield (a layer that keeps bowl water from splashing), a moving dryer, and ADA-height seating (a taller seat that meets accessibility guidelines) — and buyers rate it 4.7 stars across 290+ ratings. If quiet operation is what matters most, the Casta Diva CD-U010Max delivers a 45dB flush (about as quiet as a soft conversation) with four-season lighting. For low-water-pressure homes, the CANEST FC-001P flushes on zero inlet pressure, and if a blackout-flush backup is non-negotiable, the EPLO DP7PRO holds a replaceable battery. Match the 12-inch rough-in and confirm a nearby outlet, and one of these will fit your bathroom.
