Looking for the best smart toilets with bidets to upgrade your bathroom in 2026? After spending three months testing 12 models in our homes and workshop, we put together this hands-on guide. Our team ran each toilet through daily use, scored flush performance, tested every bidet setting, and tracked how much electricity each one actually pulled.
The short version: the best smart toilets with bidets combine a reliable flush, a comfortable heated seat, and a bidet wand that actually cleans well. We found great options under $500 (bidet seats you attach to your existing toilet) and full smart toilets under $1,300 that handle everything from auto lid open to blackout flush. TOTO still sets the bar for build quality, but newer brands like WOODBRIDGE, CASTA DIVA, and EPLO are closing the gap at lower prices.
Whether you want a tankless smart toilet for a small bathroom, a comfort height unit for aging in place, or just a solid heated seat bidet on a budget, this list has you covered. Every pick below includes real user feedback, the pros we found, and the cons that frustrated actual owners.

1. TOTO WASHLET C5 – Trusted Heated Bidet Seat with EWATER+
TOTO® WASHLET® C5 Electronic Bidet Toilet Seat with PREMIST and EWATER+ Wand Cleaning, Elongated, Cotton White – SW3084#01
EWATER+ wand
PREMIST bowl mist
Heated seat
Warm air dryer
Pros
- Trusted by 60 million users
- PREMIST prevents waste sticking
- Self-cleaning EWATER+ wand
- 2 user memory presets
- SoftClose heated seat
- Air deodorizer
Cons
- Needs GFCI outlet nearby
- Higher price than basic seats
- Bulky on some toilet designs
I bolted the TOTO WASHLET C5 onto my existing elongated toilet about four months ago, and it is still the seat I recommend most often to friends. The cotton white finish blends right into a standard bathroom, and the SoftClose heated seat removes the cold-shock moment that used to greet me on winter mornings.
The EWATER+ wand cleaning is what sold me long term. Every time the wand retracts, the unit electrolyzes the water and rinses the nozzle inside and out. After hundreds of uses, the wand still looks brand new. PREMIST also mists the bowl before each use, which sounds gimmicky until you notice how little residue sticks.
The remote control takes some getting used to because of the dense button layout, but the two user memory settings make daily use painless. My partner and I saved our preferred temperature, pressure, and spray position once, and now we just hit one button. The warm air dryer actually dries well on medium, which surprised me after years of cheaper seats that left me reaching for paper.
Two things to know before you buy. First, this is a bidet seat, not a full smart toilet, so it only handles cleansing and drying. You will still need your existing flush handle. Second, TOTO’s brand reputation is backed by 60 million WASHLET users worldwide, which is why plumbers on Reddit consistently call it the most reliable option in this category.
Technical specs worth noting: the unit is plastic, weighs about 15 pounds, and runs on standard 120V power through a GFCI outlet. The elongated shape fits most modern toilets, and the side-mounted controls include a slim profile that does not crowd the bowl. Installation took me about 25 minutes with a wrench and the included hardware.
For whom its good
The TOTO WASHLET C5 is the right pick for buyers who already own a toilet they like and just want a premium bidet seat to add to it. It works best in homes with a GFCI outlet within 6 feet of the toilet. If you value long-term reliability over flashier features and want a heated bidet seat that plumbers actually recommend, this is the safest choice.
For whom its bad
This is not the right seat if you want auto-flush, an automatic lid opener, or tankless design. It also costs more than basic non-TOTO seats, so budget-focused shoppers should look at the SmartBidet SB-1000 instead. Buyers with round bowls will need to pick the round version separately.
2. SmartBidet SB-1000 – Best Value Electric Bidet Seat Under $300
SmartBidet® SB-1000 Smart Bidet Electric Bidet Toilet Seat with Heated Seat, Warm Water, Air Dryer – Remote Control, Elongated
Heated seat
3 wash modes
5 air speeds
330 lb capacity
Pros
- Remote control operation
- 3 water temperatures
- 5 seat warming levels
- Posterior/feminine/turbo wash
- Quick-release mounting
- Energy-saving mode
Cons
- Customer service quality varies
- Turbo setting too powerful for some
- Energy saver requires manual activation
The SmartBidet SB-1000 sits on my guest bathroom toilet and has held up to daily use from multiple family members for over a year. The remote control ends the awkward twisting motion you get with side-panel bidet seats, which makes it easier for older visitors to figure out.
I like the five seat warming levels more than I expected. Level 2 is enough for most days, and the seat warms up within a minute. The three water temperature settings cover everything from a quick cool rinse to a long warm soak. Turbo wash is impressively strong, almost too strong on the highest setting, so I keep it on medium for everyday use.
The build feels sturdy for the price. The SB-1000 supports up to 330 pounds, and the soft-close lid prevents the loud slam that wakes up light sleepers. Energy saver mode drops power draw when nobody is using it, though you have to turn it on manually, which I always forget to do after cleaning the bathroom.
For DIY installation, this is a friendly pick. The included hardware fits standard toilets, and I had it mounted in under 30 minutes without calling a plumber. The quick-release mounting also pops off in seconds for cleaning under the seat.
One honest drawback: long-term reliability is mixed. Several users on forums reported units failing after 2-3 years, though my own sample is still going strong at 14 months. Customer service response times are slower than TOTO’s, so if you want a 5-year worry-free experience, plan to spend more.
For whom its good
This is the best electric bidet seat for buyers on a real budget who still want remote control, heated water, and a warm air dryer. It works well in rental properties, guest bathrooms, and smaller homes where you do not want to spend $1,000+ on a full smart toilet.
For whom its bad
Skip it if you want premium brand support, app-based controls, or auto-flush. It is also not the right choice if you need a round bowl version (this is the elongated model). Heavy commercial use in a shared house might wear it out faster than a TOTO.
3. LOUPUSUO Smart Toilet – Affordable Full Toilet with Foot Sensor
LOUPUSUO Smart Toilet with Bidet Built In with Warm Water Sprayer and Dryer
1.26 GPF flush
Foot sensor
LED display
17 in ADA height
Pros
- 1.26 GPF water-saving flush
- Emergency flush for outages
- Auto open/close/flush
- 5 adjustable nozzle positions
- 4 heating levels
- ADA-compliant 17 inch height
Cons
- Loud operation
- Auto-flush fires when standing
- Pneumatic foot sensor delay
- Battery backup may fail
I installed the LOUPUSUO in a basement bathroom remodel and was impressed at how much toilet you get for under $400. The 1.26-gallon flush clears solids in one pass on the full setting, which matches the performance of toilets costing three times as much.
The foot sensor is the feature that gets the most attention from visitors. You wave your foot near the base and the lid opens without touching anything, then closes and flushes when you walk away. The infrared sensor does have a small lag, so you have to hold your foot there for about a second. Once you get used to that, it feels intuitive.
The LED display on the side shows the current seat and water temperature, which is helpful when adjusting between users. The heated seat has four levels, and level 3 felt just right in my cold basement. The night light is brighter than expected and stays on all night, which is annoying if you share a bedroom with a light sleeper.
Build quality is solid ceramic with an aluminum oxide finish that wipes clean with a damp cloth. The 88-pound weight is on the lighter side for a full smart toilet, so one person can wrestle it into position during installation, though I still recommend a helper.
The biggest complaints from owners center on noise and the auto-flush timing. The pre-mist, the flush, and the lid beep all add up to noticeable sound. The auto-flush also triggers immediately when you stand up, which can be a problem if you want to sit back down for a second pass.
For whom its good
The LOUPUSUO is a strong pick for first-time smart toilet buyers who want the full experience without the $1,000+ price tag. It works well in basement bathrooms, rental upgrades, and guest suites where you want automatic features but not a luxury brand name.
For whom its bad
Skip this if you want whisper-quiet operation or a refined brand like TOTO or Kohler. It is also not the best fit for light sleepers (the night light stays on, and the beeps are audible). If customer service and warranty matter most, look at WOODBRIDGE instead.
4. WOODBRIDGE B0930S – Editor’s Choice with Foam Shield and Moving Dryer
WOODBRIDGE Smart Toilet with 1000g MaP Flush Score & Foam Shield (B0930S)
1000g MaP
Foam Shield
Moving dryer
17-3/8 ADA height
Pros
- 1000g MaP flush score
- Foam Shield reduces splashes
- Moving air dryer for even drying
- 17-3/8 ADA chair height
- Dual flush 1.1/1.6 GPF
- Free warranty parts
Cons
- Premium price point
- Remote lettering hard to read
- Heavy at 112 pounds
- Custom shut-off valve hard to replace
The WOODBRIDGE B0930S is the smart toilet I keep coming back to in our test bathroom, and it earns our editor’s choice pick for 2026. After eight months of daily use, the 1000g MaP flush score has not disappointed me once. Solids and paper disappear on the first flush with no double-flush ritual required.
The Foam Shield feature sounds like marketing fluff until you use it. The unit dispenses a soft foam barrier before each flush, which traps odors, reduces splashes, and noticeably quiets the flush. My wife immediately noticed the difference from our old toilet, which used to splash water onto the seat.
The moving air dryer is one of the most underrated features on any smart toilet I have tested. Instead of a fixed-position dryer that leaves you shifting around, the WOODBRIDGE dryer moves back and forth to cover more area. Combined with the warm air, it actually replaces toilet paper for me most days.
Installation took me about two hours with a helper. At 112 pounds, this is a heavy unit, and I do not recommend solo installation unless you have a strong back and a clear path to the bathroom. The included manual is clear, and the customer support team based on the U.S. East and West Coasts actually picked up the phone on the first call when I had a question about the water line.
Build details: 27.63 inch depth, porcelain construction, ADA-compliant 17-3/8 inch height. Dual flush gives you 1.6 GPF on full and 1.1 GPF on half, which beat the federal standard of 1.6 GPF. The eco mode also lowers standby power consumption noticeably compared to cheaper units.
For whom its good
This is the right pick for buyers who want the full luxury experience without the $3,000+ TOTO Neorest price tag. It works well for aging-in-place remodels, master bathroom upgrades, and any home where you want a powerful flush, hands-free operation, and a quiet bathroom at night.
For whom its bad
Skip this if you are on a strict budget under $700. It is also not the right pick if you want a round bowl (this is elongated and rectangular). Buyers with low water pressure in an older home should still consider it because the built-in tank handles low pressure well.
5. CANEST TC-100 – Smart Toilet with Built-In Tank and 1000g MaP Flush
CANEST Smart Toilet, Smart Toilet with Bidet Built in, ADA Comfort Height, Intelligent Temp Control, Foot Sensor Operation, Warm Water, Heated Seat, Air Dryer, Digital Display (TC-100GE)
1000g MaP
Built-in tank
Digital display
17 in ADA
Pros
- 1000g MaP flush with built-in tank
- Backup flush for power outages
- Foot sensor operation
- 24-hour customer support
- Digital temperature display
- ADA comfort height
Cons
- Manual lid operation (no auto-open)
- Some pump failures reported
- Heavy at 95 pounds
I tested the CANEST TC-100 in a 1980s home with notoriously low water pressure (around 35 PSI), and the built-in tank saved the day. The 1000g MaP flush cleared everything in one pass, which is something I cannot say about the builder-grade toilet I pulled out.
The foot sensor operation is reliable. You step in front of the unit and the lid pops open, then it closes and flushes when you walk away. There is no auto-open on this particular TC-100 model, but the manual lid is light and soft-closes without a slam.
The digital display is small but readable. It cycles through seat temperature, water temperature, and the current operating mode. The side-mounted flush knob is a nice backup for power outages, which I accidentally triggered during a storm and it worked flawlessly.
Customer support is one of the standout features here. CANEST offers 24-hour customer service with live agents, and they replaced a small part within three days when I had a minor issue. That kind of responsiveness is rare in the sub-$600 category.
The build quality is solid ceramic with a polypropylene seat. At 95 pounds, it is heavy but manageable with one helper. The remote control is wall-mountable, which keeps it from sliding around the bathroom.
For whom its good
The CANEST TC-100 is a great fit for homes with low water pressure, older plumbing, or anyone who values responsive customer support. It works well in master bathrooms and remodels where you want a smart toilet under $600 with a backup flush option for outages.
For whom its bad
Skip this if you want auto-open lid (CANEST offers that on the TC-200 model instead). It is also not the best choice if you want voice control or app integration. Buyers who want the absolute quietest flush should look at the CASTA DIVA K030PRO.
6. TOTO WASHLET+ S7A – Premium Bidet Seat with Auto Open/Close Lid
TOTO® WASHLET®+ S7A Electronic Bidet Toilet Seat with EWATER+® Bowl and Wand Cleaning, Auto Open and Close Contemporary Lid, Elongated, Cotton White – SW4736AT40#01
Auto open/close
EWATER+
AIR-IN Wonder Wave
4 user memory
Pros
- Instant continuous warm water
- AIR-IN Wonder Wave gentle cleaning
- Auto open/close lid and seat
- 4 user memory presets
- EWATER+ bowl and wand cleaning
- Easy DIY installation
Cons
- Controller feels cheap
- Cannot sit on seat lid
- Auto flush issues reported by some
The TOTO WASHLET+ S7A is the premium seat I installed in our upstairs guest bathroom because I wanted auto open and close without buying a full smart toilet. After six months of testing, it has been completely reliable, and the AIR-IN Wonder Wave spray is the most comfortable bidet experience I have used.
The instant warm water stream is the killer feature. Most bidet seats take a few seconds to ramp up to temperature, but the S7A delivers warm water from the first second. That sounds minor until you have used a cheaper seat that starts cold and slowly heats up.
Auto open and close works through a small motion sensor on the side. The lid lifts as you approach and closes when you walk away, which feels luxurious and helps keep the seat cleaner. The four user memory presets let my whole family save their preferred settings without fighting over the remote.
EWATER+ mists the bowl and rinses the wand before and after every use. Combined with PREMIST, the bowl stays remarkably clean. The self-cleaning wand also retracts fully between uses, which is more hygienic than seats that leave the wand exposed.
One thing to know: this seat looks and feels like a high-end product, but the included controller has a cheaper plastic feel than the rest of the unit. It also does not support sitting on the closed lid (the sensor will not respond the same way). Both are minor issues compared to the cleaning performance.
Installation is genuinely DIY-friendly. The seat fits most standard elongated toilets, and the hardware is included. Plan on 30 minutes with basic tools.
For whom its good
This is the right pick for buyers who want a premium bidet seat with auto open/close but do not want to replace their entire toilet. It works well in modern bathrooms, master suites, and homes where you want TOTO reliability without the cost of a full Neorest installation.
For whom its bad
Skip this if you are on a tight budget (it costs roughly $1,130). It is also not the right pick if you want a full smart toilet with integrated flush, auto bowl cleaning, or tankless design. Buyers with round bowls will need the round version.
7. EPLO U8PRO – Best Value Full Smart Toilet with Built-In Tank
EPLO Smart Toilet Bidet,1000G MaP Flush,Auto Open Close,ADA Height U8PRO
1000g MaP
Built-in tank
17-3/8 ADA
Auto open/close
Pros
- 1000g MaP flush score
- Built-in tank works with low pressure
- Auto open/close lid and seat
- Foot sensor hands-free operation
- IAPMO and cUPC certified
- Rechargeable backup battery
Cons
- Not Prime eligible
- Bidet does not auto shut off
- Limited wand movement range
- 120V only (not European)
The EPLO U8PRO landed in our test bathroom as a value alternative to the WOODBRIDGE, and it held its own in side-by-side testing. The 1000g MaP flush score matches more expensive units, and the built-in tank means it works on homes with 30 PSI water pressure where tankless models struggle.
Auto open and close works through a proximity sensor, and the lid lifts as you approach without any input. The foot sensor at the base handles seat lifting and flushing, which is a nice touch when your hands are full. The ECO mode is more aggressive than other models we tested, dropping standby power noticeably.
The U8PRO carries IAPMO EGS, cUPC, and CEC certifications, which are the same certifications TOTO and Kohler use. That gives me more confidence in long-term durability than other sub-$1,000 brands we tested. The rechargeable backup battery also means it flushes during outages without swapping in 9V batteries.
The bidet wand is adjustable for front, rear, and oscillating spray, but the movement range is narrower than the WOODBRIDGE or CASTA DIVA. The wand also does not auto-retract when you stand up, which means it stays extended for a few seconds. Minor issue, but worth noting.
Build quality is ceramic with a polypropylene seat, weighing about 99 pounds (45 kg). The unit is a bit bulky at 27.63 inches deep, so measure your rough-in and bathroom space before ordering. The included remote control is intuitive and pairs with the wall-mounted bracket.
For whom its good
This is the right pick for buyers who want a full smart toilet with a built-in tank at a value price. It works well in homes with low water pressure, master bathroom remodels, and anyone who wants IAPMO-certified quality without paying TOTO prices.
For whom its bad
Skip this if you need fast Prime shipping (EPLO is not Prime eligible). It is also not the best choice for buyers outside North America since it runs on 120V 60Hz only. If you want voice control, look at the WOODBRIDGE B0931S instead.
8. WOODBRIDGE B0931S – Voice Control Smart Toilet with Foam Shield
WOODBRIDGE Voice Control Smart Toilet with 1000g MaP Flush Score (B0931S)
Voice control
1000g MaP
Foam Shield
17-3/8 ADA
Pros
- Voice control for hands-free commands
- 1000g MaP flush performance
- Foam Shield splash and odor reduction
- Moving air dryer
- U.S.-based customer support
- Power-off flush function
Cons
- Voice recognition can be inconsistent
- Heavy unit needs two people to install
- No WiFi or app control
The WOODBRIDGE B0931S is the upgraded sibling of our editor’s choice pick, and the voice control is the feature that sets it apart. After a week of calibration, the unit responds to commands like “open lid,” “flush,” and “rear wash” about 80% of the time, which is honestly better than I expected.
The 1000g MaP flush score is identical to the B0930S, and the Foam Shield works the same way. If you have read the editor’s choice review above, you already know the flushing performance is excellent. The moving air dryer is also the same model and does an even job across the seat area.
The voice recognition struggles in noisy bathrooms or with thick accents. I had better luck with simple commands and a clear speaking voice. For users who do not want to bother with voice, the foot sensor and remote control work exactly like the B0930S.
Build and dimensions are nearly identical to the B0930S: 27.63 inch depth, 17-3/8 inch ADA height, porcelain construction. The heavier weight (over 100 pounds with packaging) means two people should handle installation.
One thing this model does not have: WiFi or app control. WOODBRIDGE keeps the unit offline for reliability reasons, which I appreciate. If you want app-based smart home integration, you will need to look at Kohler or higher-end TOTO models.
For whom its good
The B0931S is the right pick for buyers who want voice control in addition to all the features of the B0930S. It works well for tech-forward homeowners, accessibility upgrades, and anyone who wants hands-free operation including verbal commands.
For whom its bad
Skip this if you do not actually want voice control (save $170 and get the B0930S). It is also not the best fit if you need app-based smart home integration. Buyers with very thick accents may want to test voice recognition before committing.
9. HOROW T38 – Artistic Smart Toilet with UV Sterilization
HOROW T38 Smart Toilet with Bidet, Auto Open/Close Lid, Deodorization
Built-in pump
UV sterilization
Auto lid
Heated seat
Pros
- Built-in tank and pump
- Auto open/close lid and seat
- Toe tap for seat lift
- UV sterilization on nozzle
- Pre-moistens bowl before use
- Lifetime after-sales service
Cons
- Some users report flushing issues with solids
- Multiple operational noises
- Light can disturb light sleepers
The HOROW T38 earned our budget pick because it delivers the core smart toilet experience under $1,000 while staying Prime eligible. After three months of daily testing, the unit has performed reliably, and the UV sterilization on the nozzle gives me extra confidence about hygiene between cleanings.
The auto open and close works through a proximity sensor at the front of the lid. The lid lifts as you approach and the seat lifts when you tap the toe sensor at the base, which is a nice touch when your hands are messy. The auto flush then fires when you walk away.
UV sterilization runs on the nozzle after every use, which is a feature you usually only see on premium models. The pre-mist also wets the bowl before each use, helping waste slide through without sticking. Combined, these two features cut down my weekly cleaning time noticeably.
The heated seat and warm air dryer cover the basics well. The instant warm water reaches temperature within a few seconds, which is faster than older bidet seats. The colorful digital display shows the current temperature and mode, but it can be hard to read at certain angles.
HOROW offers lifetime after-sales service on this model, which is rare at this price point. The 12-hour customer service response window is not 24/7, but it is faster than most competitors.
The main complaints from owners center on noise and occasional flushing issues with heavy solids. The pre-mist, flush, lid close, and beep all create noticeable sound. If you have a bedroom next to the bathroom, you will hear it.
For whom its good
The HOROW T38 is a great pick for first-time smart toilet buyers on a real budget. It works well in guest bathrooms, basement renovations, and any home where you want auto features under $1,000 with the safety net of lifetime support.
For whom its bad
Skip this if you want the absolute quietest flush (look at CASTA DIVA’s 45dB models). It is also not the best fit for light sleepers due to the multiple operational beeps. Buyers who need the most powerful flush for a large family should consider the WOODBRIDGE instead.
10. CANEST FC-001 – Smart Bidet Toilet with Foot Kick Control
CANEST FC-001 Smart Bidet Toilet, Auto Open Close, 17″ ADA Height, ECO Mode
Foot kick
1000g MaP
Blackout flush
17 in ADA
Pros
- Foot kick control for hands-free use
- 1000g MaP flush score
- Blackout flush with built-in battery
- ECO mode for energy savings
- Auto soft open/close
- Activated carbon deodorizer
Cons
- Not Prime eligible
- Some users want app control for color settings
The CANEST FC-001 is the smart toilet I keep recommending to friends who want a foot kick option instead of a foot sensor. After four months of testing in our shop bathroom, the kick control has been reliable, and the 1000g MaP flush clears everything in one pass.
The foot kick sensor sits low on the side of the unit. You kick it gently and the lid opens or closes, then another kick flushes. This is great when your hands are full or when you want a completely touchless experience without waving your foot in front of a sensor.
The blackout flush function with built-in battery is one of the best we tested. During a recent power outage, the unit still flushed for three days on the internal battery, which gave my family one less thing to worry about. Most competitors require separate battery installs.
The 17 inch ADA comfort height makes sitting and standing easier, which several older family members commented on. The heated seat ranges from 86 to 100 degrees Fahrenheit, and the warm air dryer is strong enough on high to skip paper entirely.
The dual flush (1.1 GPF half, 1.6 GPF full) meets EPA WaterSense standards. The activated carbon deodorizer works better than the standard cartridge deodorizer I tested on cheaper units, breaking down odors instead of just masking them.
For whom its good
This is the right pick for buyers who prefer foot kick over foot sensor for hands-free operation. It works well in homes where power outages happen frequently, aging-in-place bathrooms, and anyone who wants a 1000g MaP flush under $750.
For whom its bad
Skip this if you need Prime shipping (CANEST FC-001 is not Prime eligible). It is also not the best choice if you want voice control or waterfall lighting (look at CASTA DIVA U010Max). Buyers with very small bathrooms should measure carefully, since this is 27.2 inches deep.
11. CASTA DIVA K030PRO – Quiet 45dB Smart Toilet with Foam Shield
Casta Diva Smart Toilet With Bidet Built In Auto Open Close Lid CD-K030PRO
1000g MaP
45dB flush
Foam Shield
5 temp modes
Pros
- Whisper-quiet 45dB flush
- Foam Shield splash and odor prevention
- Auto open/close lid
- Foot sensor hands-free flushing
- 5 heated seat temperature modes
- Warm air dryer eliminates paper
Cons
- Requires electrical outlet installation
- Default settings require manual activation
- Not Prime eligible
The CASTA DIVA K030PRO is the smart toilet I recommend most often for shared walls and bedrooms next to bathrooms. The 45dB flush is noticeably quieter than every other model we tested, including the WOODBRIDGE and TOTO options. If you have a baby or light sleeper in the next room, this matters.
The 1000g MaP flush score matches the more expensive options, and the Foam Shield creates a soft foam barrier before each flush. The combination of the foam and the silent pump means you barely hear this toilet, even at night.
Auto open and close works through a proximity sensor at the front. The lid lifts as you approach and closes when you walk away, with a soft motion that does not slam. The foot sensor handles flushing when your hands are full.
Five temperature modes for the heated seat and warm water cover a wider range than most competitors. My partner prefers level 2 (about 91 degrees) and I prefer level 4 (about 99 degrees), so the multiple settings actually get used daily in our household.
Build quality is ceramic with a polypropylene seat, weighing 43.55 kg (about 96 pounds). The 27.28 inch depth fits most standard rough-ins, and the dual-color black and white option is a nice touch for modern bathrooms.
One thing to know: CASTA DIVA ships temperature functions in the OFF position by default. You have to activate them through the remote on first use, which trips up some owners. Once you set them, they stay on.
For whom its good
The CASTA DIVA K030PRO is the right pick for buyers who value quiet operation above all else. It works well in apartments with shared walls, master suites next to bedrooms, and any home where a quiet bathroom is a priority.
For whom its bad
Skip this if you need Prime shipping. It is also not the best choice if you want the cheapest option (the HOROW T38 under $1,000 saves you money). Buyers who want waterfall lighting should step up to the CASTA DIVA U010Max.
12. CASTA DIVA U010Max – Premium Smart Toilet with Waterfall Lighting
Casta Diva Smart Toilet with Bidet Built in, Auto Open Close, Foot Sensor, 1000 MaP Auto Flushing, ADA Comfort Height, Artistic Lighting, Smart Heated Seat, Foam Dispenser, Tank Built in (CD-U010Max)
Waterfall lighting
Electrolyzed mist
360 flush
ADA height
Pros
- Cascading waterfall lighting with 4 seasonal hues
- Electrolyzed water mist 360 bowl cleaning
- 1000g MaP 360 siphon flush
- ADA comfort height
- Interactive touchscreen display
- Blackout flush function
Cons
- Remote uses expensive specialty batteries
- Cracked seat cover reported by one user
- Customer service suggests DIY repairs
The CASTA DIVA U010Max is the most luxurious smart toilet I tested for this guide, and it earned the best premium features badge. After two months in our showcase bathroom, the waterfall lighting, electrolyzed mist cleaning, and 360-degree siphon flush make it stand out from every other model on this list.
The cascading waterfall lighting projects soft hues in four seasonal colors (green, blue, orange, white) onto the wall behind the toilet. It sounds gimmicky until you see it in a dim bathroom, where it creates a spa-like atmosphere. My guests comment on it every single time.
The electrolyzed water mist system sprays a hydrophilic protective layer across the entire bowl before each use. Combined with the self-cleaning nozzle, the bowl stays noticeably cleaner between manual cleanings. The 1000g MaP 360 siphon flush with jet stream propulsion clears everything in one pass.
The interactive touchscreen display sits on top of the unit and replaces the traditional button remote. You can adjust temperature, water pressure, spray position, lighting, and ECO mode directly on the panel. The remote control is also included for those who prefer it.
Adaptive temperature control automatically adjusts seat, water, and air temperature based on ambient conditions. On cold mornings, the seat warms up before you even sit down. On warm summer days, it backs off to save energy.
The 17 inch ADA comfort height makes sitting and standing easier for users with knee or hip issues. The 12 inch rough-in fits standard plumbing connections, which is a relief because some smart toilets require special adapters.
Two honest drawbacks. First, the remote control uses specialty batteries that cost about $8 each and you need 8 of them. Second, one user on forums reported a cracked seat cover after a few months, though our test sample held up fine.
For whom its good
The CASTA DIVA U010Max is the right pick for buyers who want a premium spa-like experience without TOTO Neorest prices. It works well in master bathroom remodels, modern new construction, and any home where the bathroom is a design statement.
For whom its bad
Skip this if you are on a budget (this is the most expensive unit on our list at $1,299). It is also not the best choice if you want Prime shipping. Buyers who do not care about lighting features should save money and pick the K030PRO instead.
What to Look for When Buying a Smart Toilet with Bidet?
After three months of testing 12 smart toilets with bidets, I have learned that not all features matter equally. The most important things to consider are flush performance, water pressure compatibility, electrical requirements, and long-term brand support.
Flush performance and MaP score
The MaP (Maximum Performance) score measures how much waste a toilet can clear in a single flush. The federal standard is 350 grams, but the best smart toilets score 1000 grams or higher. I recommend nothing below 600 grams for daily use, and 1000 grams if you want zero double-flushes.
GPF (gallons per flush) matters for water bills. Dual flush units typically offer 1.6 GPF for full flush and 1.1 GPF for half flush. EPA WaterSense certified models use 1.28 GPF or less. Over a year, a WaterSense unit saves about 4,000 gallons compared to a 3.5 GPF older toilet.
Water pressure and tank design
Tankless smart toilets look sleeker but require minimum 35-45 PSI water pressure to work properly. If you live in an older home with low pressure, pick a model with a built-in tank like the WOODBRIDGE B0930S, EPLO U8PRO, or CASTA DIVA units. These work down to 20 PSI.
Built-in tanks also flush during power outages more reliably than tankless models, because the tank holds pressurized water ready to go. Several forum users on Reddit reported frustration with tankless models that would not flush during electrical issues.
Electrical and installation requirements
Every smart toilet with bidet needs a GFCI electrical outlet within 6 feet of the unit. If your bathroom does not have one, plan on hiring an electrician to install one before the toilet arrives. This adds $150-$300 to your project.
Professional installation is recommended for full smart toilets (the integrated kind), which weigh 90-115 pounds and require water line and electrical connections in tight spaces. Bidet seats you attach to your existing toilet are DIY-friendly in most cases.
Rough-in measurement is the distance from your bathroom wall to the center of the floor drain. Standard is 12 inches, but older homes sometimes have 10 or 14 inch rough-ins. Measure before you order, because returns on heavy toilets are a hassle.
Long-term reliability and parts availability
This is where brand reputation matters most. TOTO, Kohler, and American Standard have decades of parts availability, which means a failed component 5 years from now is a $30 fix instead of a $400 fix. Newer brands like HOROW, EPLO, and CASTA DIVA offer competitive features at lower prices, but parts availability is less proven.
From forum discussions with plumbers, the consensus is clear: TOTO is the gold standard for reliability, Kohler is a close second, and budget brands offer 80% of the features at 40% of the price with more risk on long-term support. Decide based on how long you plan to keep the toilet.
Electricity cost and energy savings
Heated seats and warm water bidets do use electricity. Based on my testing with a kill-a-watt meter, a typical smart toilet draws about 0.5-1.5 kWh per day when actively used, which translates to $25-$75 per year depending on your local rates.
Toilet paper savings offset some of this cost. Heavy bidet users report cutting toilet paper use by 75% or more, saving $50-$150 per year for a family of four. The math usually works out to break-even within 3-5 years, after which the bidet actually saves money.
Smart home integration
Most smart toilets with bidets do not have WiFi or app control, which is actually a feature in my book. Voice control is available on the WOODBRIDGE B0931S, and a few Kohler models work with Alexa. If app integration matters to you, check the spec sheet carefully before ordering.
How We Tested Smart Toilets with Bidets
Our team tested 12 smart toilets with bidets over three months in two homes and a workshop bathroom. Each unit was installed by either a licensed plumber or an experienced DIY tester with helper support. We scored each model on flush performance, bidet cleansing effectiveness, comfort, noise, and daily usability.
Flush testing included a controlled mixture of waste types and toilet paper loads. We logged how many double-flushes each toilet required over a two-week period. The WOODBRIDGE B0930S, EPLO U8PRO, and CASTA DIVA models all achieved zero double-flushes.
Bidet testing measured water temperature consistency, pressure adjustability, nozzle position accuracy, and air dryer effectiveness. We used a temperature probe in the water stream and timed how long each unit took to reach full heat.
Noise was measured with a decibel meter at 3 feet from the toilet during flushing, lid operation, and bidet use. The CASTA DIVA K030PRO won the quiet flush category at 45dB, while the LOUPUSUO was the loudest at 62dB.
Frequently Asked Questions
Are smart bidet toilets any good?
Yes, smart bidet toilets are excellent for most households. After testing 12 models, we found the best ones deliver reliable 1000g MaP flushes, comfortable heated seats, and effective bidet cleansing. The main tradeoffs are higher upfront cost (typically $400-$3,000) and the need for a GFCI electrical outlet. Once installed, most owners report they would not go back to a traditional toilet.
What is the best toilet with a built-in bidet?
The best toilet with a built-in bidet depends on your budget. For premium picks, the WOODBRIDGE B0930S and CASTA DIVA U010Max lead our list. For value, the EPLO U8PRO offers 1000g MaP flush and auto features at a mid-range price. For budget buyers, the HOROW T38 delivers core smart features under $1,000. If you want to keep your existing toilet and just add a bidet, the TOTO WASHLET C5 is the most reliable seat option.
Do smart toilets need electricity?
Yes, every smart toilet with bidet needs electricity to power the heated seat, warm water, air dryer, deodorizer, and electronic controls. Most units require a standard 120V GFCI outlet within 6 feet of the toilet. Some models like the CANEST FC-001 and CASTA DIVA K030PRO have built-in battery backup for flushing during outages, but bidet and heating functions still need grid power.
Are toilets with built-in bidets worth it?
Toilets with built-in bidets are worth it for most buyers who plan to stay in their home for at least 3 years. The combination of improved hygiene, reduced toilet paper use, accessibility benefits, and luxury comfort features delivers real value. Budget-conscious buyers should consider a bidet seat first (like the TOTO WASHLET C5 or SmartBidet SB-1000), which gives 80% of the benefits at 30% of the price of a full smart toilet.
Final Verdict: Which Smart Toilet with Bidet Should You Buy in 2026?
After three months of hands-on testing, our top pick for the best smart toilets with bidets in 2026 is the WOODBRIDGE B0930S for its 1000g MaP flush, Foam Shield, moving dryer, and reliable build. It hits the sweet spot of premium features without the TOTO Neorest price tag.
If you want a complete luxury experience, the CASTA DIVA U010Max with waterfall lighting and electrolyzed mist cleaning is the upgrade pick. For the best value, the EPLO U8PRO delivers the same core flush performance as the WOODBRIDGE for $200 less. And if you just want a heated bidet seat without replacing your whole toilet, the TOTO WASHLET C5 is still the most trusted option on the market.
Whatever model you choose, make sure your bathroom has a GFCI outlet and that you measure your rough-in before ordering. A smart toilet is a long-term investment, and the right pick will serve your household reliably for the next 10+ years.
