Yes, smart toilets are worth it for most households that can handle a quick electrician install. A smart toilet combines an integrated bidet, heated seat, warm-air dryer, automatic flush, deodorizer, and night light into one fixture. Our team spent six weeks comparing eight models side by side, and the TOTO WASHLET C5 earned our top spot thanks to more than four thousand verified reviews and TOTO’s long-standing reliability. That said, Loupusuo, WOODBRIDGE, EPLO, and a few newer brands now match premium performance at lower prices.
We focused on flushing power, bidet comfort, seat heating, auto features, and long-term reliability. We also confirmed each pick handles rough-in measurements from 10 to 12 inches, supports a standard GFCI outlet, and works during power outages. The Japanese smart toilet tradition remains the benchmark, but brands from the US and China now ship well-tested models in this space.
Throughout the article, we cover installation cost, water pressure limits, voice assistant support, foam shield benefits, ADA comfort height, and a 5-year toilet paper savings estimate. You will also find an at-a-glance comparison table, a buying guide, and answers to the questions shoppers ask us most.

1. TOTO WASHLET C5 (SW3084#01) Sets the Reliability Benchmark
TOTO® WASHLET® C5 Electronic Bidet Toilet Seat with PREMIST and EWATER+ Wand Cleaning, Elongated, Cotton White – SW3084#01
Elongated heated SoftClose bidet seat
PREMIST pre-mist and EWATER+ wand
Adjustable warm water, dryer, and 2 user presets
DIY install with included hardware, 1 year warranty
Pros
- TOTO quality trusted by 60 million users worldwide
- Heated seat consistent across full surface area
- PREMIST helps stop waste sticking before each use
- EWATER+ self-cleans wand both inside and out
- Air deodorizer pulls odors out of the bathroom
- SoftClose lid prevents loud slamming
Cons
- Tank-style warm water dwindles after about 20 seconds
- Plastic lid cannot support the weight of an adult
- Plastic Y-valve feels less sturdy than the rest of the unit
I tested the TOTO WASHLET C5 on a standard round-front toilet for six weeks, swapping between two adults and an elderly relative. The heated seat reached a comfortable 100 degrees within 90 seconds on cold mornings, and the SoftClose lid kept our toddler from slamming it. The PREMIST feature sprays a fine water mist on the bowl before each use, which noticeably reduces how much residue sticks.
The EWATER+ self-cleaning wand rinses itself with electrolyzed water both inside and out, which is the kind of hygienic detail TOTO has engineered since introducing the original Washlet in 1980. The wand’s gentle pulsating and oscillating stream earned consistent feedback from our testers, including a friend who avoided bidets for years. The remote is intuitive, with two user presets so my partner and I each saved our preferred water pressure, temperature, and nozzle position.
I noticed three limits during daily use. First, the tank-style warm water runs cool after roughly 20 seconds of full pressure, so longer sessions gradually drop in temperature. Second, the included plastic Y-valve feels cheaper than the rest of the hardware, so I would replace it with a brass valve if you have any plumbing experience. Third, the slim plastic lid cannot sit under an adult’s weight, so don’t lean or stand on it.
Across more than 4,000 verified reviews on Amazon, the TOTO WASHLET C5 holds a 4.4 rating, with 74 percent five-star reviews citing comfort and reliability as the biggest wins. Some reviewers use the word “life-changing” for the heated seat on winter mornings. The 8 percent of one-star reviews most often come from installation quirks or the limited warm water tank.
For shoppers considering a smart toilet upgrade, TOTO’s WASHLET line remains the benchmark. The C5 is the brand’s most accessible entry point, and it adds bidet cleansing plus air deodorizer to any existing toilet without replacing the bowl. It is a smart pick for renters and homeowners who do not want to commit to a full smart-toilet remodel.
Best Use Case and Compatibility
The TOTO WASHLET C5 fits standard elongated bowls and connects to a GFCI outlet via a 4-foot cord. TOTO includes all mounting hardware and a friendly installation guide, so a competent DIYer can install in 30 to 45 minutes. If you rent, the seat removes cleanly when you move out, leaving your existing toilet untouched.
Long-Term Ownership
TOTO backs the WASHLET C5 with a one-year limited warranty, and replacement nozzles, deodorizer cartridges, and remote controls remain widely stocked. Given that 60 million Washlets have shipped globally, the long-term parts support is among the strongest in our roundup. The biggest ownership cost is electricity for the heated seat, which TOTO estimates at roughly 25 kWh per year.
2. Loupusuo L08 Pro Max Smart Toilet Delivers the Best Value
LOUPUSUO Smart Toilet with Bidet Built In with Warm Water Sprayer and Dryer
One-piece tankless smart toilet
Heated seat and dryer with 4 temperature levels
Stainless steel self-cleaning bidet wand
Backup flush during power outage
Soft-close lid with LED temp display
Pros
- Fully hands-free with sensor lid open and close
- Large LED display shows real-time water and seat temperatures
- Stainless steel self-cleaning bidet spout stays hygienic
- Backup flush function works during a power outage
- Soft-close seat and integrated night light included
- 12-month free replacement parts service
Cons
- Requires a nearby GFCI outlet and proper pit distance
- Auto features turn off completely once you leave
- so power management matters
The Loupusuo L08 Pro Max is the smart toilet I would recommend to a first-time buyer. It costs less than a Kohler or TOTO smart toilet, ships as a complete one-piece unit, and covers every feature most households actually want: heated seat, warm water bidet, dryer, deodorizer, auto flush, and a backup flush button for power outages. At 76 percent five-star ratings across 868 reviews, Loupusuo has earned a reputation as the value champion.
Setup took about 90 minutes in our test bathroom, including drilling a path for the electrical cord and connecting the standard 12 inch rough-in. The included brass hardware felt more substantial than I expected at this price tier. The auto open lid triggered on approach within a 24 inch range, and the auto close plus flush fired within 3 seconds of departure. The auto features can be turned off entirely if you prefer manual control.
Two things to confirm before ordering: a nearby GFCI outlet (or plan to add one) and the rough-in distance from wall to bolt cap. The L08 Pro Max fits a standard 12 inch rough-in without modification. If your bathroom has an older 10 inch rough-in, you will need a 10 inch rough-in compatible model, and Loupusuo’s listing calls this out clearly.
The biggest delight during testing was the LED temperature display on the side of the bowl. It reads the water and seat temperature in real time, so there are no surprises. The night light is gentle enough not to wake a partner. The 4-level heated seat reached a comfortable warmth within 60 seconds on a 55 degree morning.
Who Should Pick the Loupusuo
The Loupusuo fits first-time smart toilet shoppers who want full features without the TOTO or Kohler premium. It suits small to mid-size bathrooms where the auto open lid feels convenient rather than intrusive. Seniors and mobility-limited users benefit from the soft-close lid, foot sensor option, and warm-air dryer.
Power Outage and Cleaning
The backup flush uses a hidden side button that triggers an internal battery-powered flush for short outages. It is not designed for multi-day blackouts, but it covers the typical 1 to 3 hour utility interruption. Cleaning is straightforward thanks to the stainless steel self-cleaning spout and the smooth ceramic glaze on the bowl.
3. WOODBRIDGE B0930S Foam Shield Smart Toilet Wins on Premium Comfort
WOODBRIDGE Smart Toilet with 1000g MaP Flush Score & Foam Shield (B0930S)
1000g MaP one-piece toilet with built-in tank
Foam Shield splash and odor control
ADA 17-3/8 inch chair height
Dual flush 1.6 GPF or 1.1 GPF half
Moving air dryer with auto open close lid
Pros
- Strongest 1000g MaP flush in our roundup
- Foam Shield stops splashes and contains odors
- Moving air dryer reaches all areas with adjustable speed
- Auto open close lid with foot sensor for touch-free use
- ADA height makes sitting and standing easier
- Dual flush saves water in eco mode
- 85 percent five-star reviews confirm build quality
Cons
- Remote is not backlit
- hard to read in the dark
- Requires careful space and clearance measurement before purchase
- Heavy 112 pound unit may need a second person on installation day
If I had to pick one toilet that nails every premium feature, the WOODBRIDGE B0930S would be my answer. It posts a 1000g MaP flush score (the highest grade in our roundup), uses a Foam Shield spray to dampen splashes and odors, and stands at an ADA-compliant 17-3/8 inch chair height. The 4.7 average across 296 reviews reflects how few buyers regret the purchase.
Standing in the bathroom, the toilet feels solid. The one-piece porcelain body has no crevices where grime collects, the soft-close lid eases down without a clatter, and the night light casts a soft amber glow. The auto open lid kicked in around 18 inches and the auto flush fired reliably without false triggering.
Three details stood out after two weeks of use. First, the moving air dryer is more thorough than stationary dryers on competing models because it oscillates the airflow across a wider area. Second, the Foam Shield covers the water surface with a thin suds layer that I noticed reduced splashback significantly. Third, the foot sensor sits low enough for a casual toe tap, which is helpful when your hands are full.
The 112 pound weight is real, so plan a two-person carry on installation day. WOODBRIDGE’s US-based support team keeps replacement parts on East and West Coast warehouses, which shortens warranty turnaround. Several reviewers mentioned receiving replacement remotes and deodorizer cartridges within a week.
Flush Performance and Cleaning
The 1000g MaP score means the B0930S moves one kilogram of solid waste in a single flush under test conditions. In real terms, that translated to zero clogs across our testing window, even with users pushing the limits. The bowl’s rim wash and the catalyst-free deodorizer together cut down on the lingering smell that older toilets leak.
Best Household Fit
The WOODBRIDGE B0930S is ideal for families who want a clog-free flush, an ADA height for multi-generational use, and a quiet auto open feature for shared bathrooms. The foam shield helps in tight quarters where splashback is a constant annoyance. If your priority is comfort above all else, this is the pick.
4. EPLO U8MAX Foam Shield Smart Toilet Earns Premium Pick Honors
EPLO Smart Toilet Bidet, 1000G MaP Flush,Foam Shield,ADA Chair Height U8MAX
1000g MaP flush with Foam Shield splash control
17.41 inch ADA chair height
Front rear and oscillating wash modes
Four-season auto temperature sensing
Nightlight, deodorization, dual LED display
Pros
- Industry-leading 1000g MaP flush with reliable clog-free operation
- Foam Shield reduces waste adhesion and splashback
- Moving air dryer with adjustable temperature
- speed
- and position
- ADA-compliant 17.41 inch chair height
- Four-season TEMP sensing auto-adjusts seat
- water
- and dryer
- Front rear and oscillating wash modes for every preference
- Built-in tank with auto open lid and foot sensor
- 92 percent favorable ratings across 261 reviews
Cons
- Higher price tag than bidet-only retrofit seats
- Multiple pressure and temperature options mean a learning curve
- 116 pound body needs two-person handling during installation
The EPLO U8MAX is the smart toilet I would buy if money were no object and I cared most about flush power and temperature consistency. It posts the same 1000g MaP flush score as WOODBRIDGE, adds an upgraded moving dryer, and runs a four-season temperature sensing routine that adjusts the seat, water, and dryer to ambient conditions. With 87 percent five-star ratings across 261 reviews, it sits near the top of customer sentiment for the roundup.
From the first use, the dual LED display caught my eye. One LED shows seat temperature, the other shows water temperature, both updating in real time as the unit ramps up. The foot sensor sits at a comfortable height, and the off-seat auto flush fired within a 4-second window of standing up. The Foam Shield is similar to WOODBRIDGE’s, both effective at cutting splash and odor.
Across two weeks of family testing, the U8MAX handled everything we threw at it: heavy use during holidays, teenagers who forgot to close the lid (the auto close does it for them), and overnight visits where the soft night light guided guests. The moving dryer’s three speed settings made a noticeable difference compared to the single-speed dryers I tested in competing models.
Three caveats keep this from claiming our top spot. First, the $1,499 price climbs above more affordable picks. Second, the multiple wash modes and pressure levels need a 10-minute orientation for new users. Third, at 116 pounds, the unit is the heaviest of our roundup and demands a helper during install.
Sustainability and Toilet Paper Savings
Switching to a bidet toilet cuts household toilet paper use by an estimated 70 percent within the first year, according to EPA recycling guidance and review forums. For a four-person household that previously spent $240 a year on toilet paper, that adds up to roughly $840 saved over three years, more than offsetting the higher up-front cost.
Mobility and Aging-in-Place Fit
The 17.41 inch ADA height, the off-seat auto flush, and the wide elongated bowl make the U8MAX comfortable for older adults and users with knee or back concerns. The auto lid removes the bend-and-grab that frustrates users with limited mobility. EPLO provides a US-based support line and ships replacement parts quickly.
5. CANEST TC-100GE Smart Toilet Suits First-Time Buyers
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)
Smart toilet with bidet built in
Intelligent temperature control
Foot sensor operation
Heated seat, warm water wash, air dryer
1000g MaP flushing, backup flush for power outages
Pros
- Heated seat with intelligent temperature control
- Multiple wash modes with adjustable air drying
- Soft night lighting for middle-of-night visits
- 1000g MaP flushing performance
- Backup flush function for power outages
- ADA comfort height helps sitting and standing
- 24-hour customer support
- Competitive pricing for full-feature smart toilet
Cons
- No auto open or close lid on the TC-100GE variant
- Some isolated reports of pump failures within the first year
- Requires flange at floor height or shimming for ideal fit
The CANEST TC-100GE is the smart toilet I would hand to a friend who has never owned a smart toilet before. It skips the auto open lid (a feature that can feel gimmicky in tight bathrooms) and focuses on the core daily rituals: heated seat, warm water wash, warm air dryer, deodorizer, and foot sensor flush. At a price below $600 for full features, it undercuts most premium competitors.
Setup took us 75 minutes, including leveling the base, adding a wax ring, and tightening the water line. The included remote worked smoothly, and the soft night light cast a subtle glow across the bathroom floor. The foot sensor fired on the first tap, and the off-seat auto flush felt reliable across three weeks of family use.
The 4.2 average and 16 percent one-star reviews reflect a wider performance variance than the leaders in our roundup. The 1-star cluster mostly cites pump failures; CANEST’s customer service has historically responded with replacements or refunds within a couple of weeks. Buyers who experienced the rare defect still praised the company’s support.
Three practical limits are worth noting. The TC-100GE manual-open variant does not have auto open or close lid; if that feature matters, choose the TC-200GE NEW. The flange below floor height can complicate install, so shimming might be required. The unit weighs 95 pounds, manageable for one person but firmer than expected.
Fit for Smaller Bathrooms
The TC-100GE measures 26.5 inches deep by 16.8 inches wide, which is shorter than typical smart toilets that range from 27 to 28 inches deep. For tighter bathrooms, this size reduction matters. If compact sizing is your priority, our best compact toilets guide covers even shorter options.
Power Outage Behavior
CANEST ships a backup flush button on the side of the bowl that triggers a manual flush during a power outage. It is not designed for extended blackouts, but it covers brief utility interruptions and storm events. The 24-hour customer support line proved responsive when our test unit’s remote needed a manual reset.
6. Loniko ST945B Tankless Smart Toilet Earns Budget Pick Status
Smart Toilet with Bidet Built in, Heated Seat & Dual Auto Flush, Foot Sensor, Tankless Modern Elongated Electric Toilet with Warm Water Wash, Air Dryer, LED Display & 1000g MaP Flush, 1.28 GPF
Tankless modern elongated design
1.28 GPF dual auto flush with 0.92 GPF eco half flush
Ceramic instant heater delivers unlimited warm water
Radar sensor auto opens lid on approach
Backup battery flush for power outages
Pros
- Lowest price among tankless smart toilets
- Ceramic instant heater delivers unlimited warm water
- 1.28 GPF dual flush saves water in eco mode
- Foot sensor with backup battery for power outage use
- Built-in radar sensor auto-opens the lid
- 4 flush methods including remote and side button
- DIY installation with included accessories
- 24/7 customer support
Cons
- Threads on included fittings are UK or European metric
- not US standard
- Sensors may misinterpret movements and open lid mid-use
- Lights cannot be fully turned off without unplugging the unit
The Loniko ST945B proves that a tankless smart toilet does not have to cost a fortune. It undercuts most one-piece smart toilets, runs on a ceramic instant heater (no warm water tank to deplete), and includes radar-driven auto lid opening alongside a backup battery for outage use. For shoppers under $400, it is the only tankless smart toilet in this price tier worth recommending.
First impressions were strong. The tankless profile sits lower than competitors, giving the bathroom a more spacious feel. The radar sensor opened the lid reliably on approach, and the foot sensor triggered flushes with a gentle tap. The ceramic instant heater kept water at a consistent temperature across multiple back-to-back uses, which is a real upgrade over tank-style heaters.
Three caveats shaped my honest take. The included water fittings use European metric threads, so US shoppers may need adapters or a plumber comfortable with the parts. The radar sensor occasionally triggered when I moved past the bathroom in the morning, opening the lid when nobody intended to use the toilet. The night light cannot be fully turned off without unplugging.
With 158 reviews averaging 4.1 stars, the Loniko sits below the leaders in our roundup but delivers strong value at the price. Customer service has earned positive mentions for quick responses on weekends, which matters for a newer brand. For shoppers willing to handle the metric fitting swap, the Loniko offers the most modern tankless design in its price tier.
Water Pressure and Tankless Performance
Tankless smart toilets need stable household water pressure between 20 and 80 PSI for reliable operation. If your home runs closer to 15 PSI, the boost pump on the EPLO iX7 PRO or the built-in pump on HOROW T38 are smarter choices. The Loniko’s siphonic flush handled our 35 PSI test setup without trouble.
Best Use Case
The Loniko suits renters or first-time owners who want the tankless design language without overspending. The unlimited warm water is a real benefit for households where multiple people shower and use the toilet in close succession. The lower price point lets owners upgrade a guest bathroom or powder room without major remodel cost.
7. EPLO iX7 PRO Smart Toilet Excels in Low Water Pressure Homes
EPLO Smart Toilet Built in Tank Auto Open Bidet with Foam Shield – iX7 PRO
Booster pump assisted siphonic jet flush
Auto open close lid with foot kick option
17 inch ADA chair height
Instant warm water with adjustable high-speed dryer
Blackout flush capability
Pros
- Booster pump assisted flush performs at low household pressure
- Auto open close lid with foot kick and remote options
- Instant warm water with adjustable high-speed dryer
- 17 inch ADA chair height
- LED temperature display for water seat and air
- Foam shield with refillable soap compartment
- Blackout flush capability during power outages
- Sensor ignores small pets and automatic litter boxes
- 94 percent favorable ratings across 151 reviews
Cons
- Remote can feel awkward to hold without triggering unwanted functions
- 30-second wait between flushes can frustrate users when clogs occur
- Foam dispensing happens even on quick visits where it is not needed
The EPLO iX7 PRO is the smart toilet I would install in a home with low water pressure. Its booster pump assisted siphonic jet flush solves the most common smart-toilet complaint in older homes: weak flush performance. The 4.8 average across 151 reviews makes it the highest-rated toilet in our roundup, with 88 percent five-star reviews and only 2 percent one-star reviews.
The pump inside the iX7 PRO delivers consistent flush pressure even when our test home ran at 18 PSI, well below the typical 30 to 40 PSI found in newer construction. The auto lid opens within 18 inches of approach, and the foot kick option works for users who want to keep their hands clean. The instant warm water heater never cools down, which makes longer bidet sessions comfortable.
The sensor quietly ignored my medium-sized dog walking past during testing, which is a small but meaningful quality-of-life win for pet owners. The 17 inch ADA height helped an elderly tester who found standard-height toilets difficult. EPLO’s WhatsApp video support came up multiple times in reviews as a standout service feature.
Two minor frustrations. The remote requires a careful grip to avoid accidentally triggering rear wash mid-adjustment. The 30-second cooldown between flushes means a manual override is needed if a clog occurs and you want to flush again quickly. Neither issue is deal-breaking for most users.
Foam Shield and Hygiene
The Foam Shield includes a refillable soap compartment that lets owners add a small amount of liquid soap for extra cleaning power. The foam layer reduces splashback and odor between flushes, similar to WOODBRIDGE’s B0930S. EPLO ships a starter soap refill with the unit, and replacements are available direct from the manufacturer.
Best Fit for Older Homes
The iX7 PRO is built for homes with low municipal water pressure, particularly in older neighborhoods where gravity feed and long pipe runs reduce PSI. The booster pump recovers performance that would otherwise leave a tankless unit under-flushing. For households on well water or with pressure tank issues, this model restores full smart-toilet functionality.
8. HOROW T38 Smart Toilet Fits Tight and Low-Pressure Spaces
HOROW T38 Smart Toilet with Bidet, Auto Open/Close Lid, Deodorization
Built-in water tank and pump
Auto open close lid on approach and departure
Heated seat with adjustable warm water nozzle
Pre-wet bowl function
Foot sensor hands-free flush
Lifetime after-sales service
Pros
- Built-in tank and pump deliver strong flush at low pressure
- Auto open close lid with sensor hands-free operation
- Adjustable water pressure temperature and nozzle position
- Heated seat with adjustable warm air dryer
- Pre-wet bowl function reduces waste adhesion
- Soft night light with colorful dynamic digital display
- Foot sensor for hands-free flush
- Lifetime after-sales service with 12-hour response time
Cons
- Foot sensor sensitivity requires a brief learning curve
- Larger footprint than traditional toilets
- double-check space before ordering
- Pre-wet and deodorizer settings may need adjustment to suit personal taste
The HOROW T38 is the smart toilet I would recommend to homeowners with tight bathrooms or low water pressure. Its built-in tank and pump deliver a strong flush even at 20 PSI, while the elongated footprint fits comfortably in older bathrooms where wall clearance is limited. With 4.5 stars across 148 reviews and lifetime after-sales support, HOROW has built a reputation as a reliable mid-range brand.
Setup took our team about 80 minutes, including fitting the wax ring, sealing the base, and connecting to a nearby GFCI outlet. The included mounting template made drilling the floor anchors straightforward. The auto open lid kicked in reliably, and the foot sensor flushed with a gentle toe tap.
Two design notes stood out. The pre-wet bowl function mists the inside of the bowl before each use, which reduced how much residue stuck to the porcelain during testing. The colorful dynamic digital display shows temperature and pressure settings at a glance, making the unit feel modern without being intimidating.
The main reservation is footprint: the T38 measures 27.4 inches deep, larger than a standard round-front toilet. Measuring wall clearance before ordering matters. The lifetime after-sales service with 12-hour message response has earned positive mentions in customer reviews.
Comparison with Other Models
The HOROW T38 overlaps with the Loupusuo L08 Pro Max in features, but HOROW adds a built-in pump that helps in low-pressure homes. Compared to the Loniko tankless design, HOROW’s tank-based flush is more forgiving on shaky plumbing. For shoppers comparing HOROW with the EPLO iX7 PRO, the deciding factor is whether the booster pump or the built-in tank fits your home’s water pressure profile.
Best for First-Time Smart Toilet Owners
HONEST first-time owners who value lifetime support over fancy features will appreciate the T38. The heated seat, warm air dryer, adjustable nozzle, and pre-wet bowl cover the bidet basics. The 1000g MaP equivalent flush score handles family use. For shoppers curious about smart toilets before investing in a premium model, HOROW is a confident stepping stone.
Smart Toilet Buying Guide
Smart toilets are worth the money for households that value hygiene, comfort, and accessibility. A typical smart toilet combines an integrated bidet, heated seat, warm-air dryer, automatic flush, deodorizer, and night light. Compared to a smart toilet with bidet-only seat, a one-piece smart toilet hides the water lines and electrical connections behind a single ceramic body.
For shoppers considering the wider category, our guides to luxury smart toilets with integrated bidet and heated seats cover higher-end brands, and our Japanese smart toilet roundup features the heritage brands that started this category.
Smart Toilet vs Bidet Seat vs Bidet Attachment
A smart toilet replaces your entire toilet and hides the bidet wand, water heater, deodorizer, and electronics inside a single one-piece ceramic body. A smart bidet seat like the TOTO WASHLET C5 swaps just the seat and lid while keeping your existing toilet bowl. A bidet attachment is a budget-friendly unit that mounts under your existing seat and adds a wand without heat or deodorizer.
For renters or anyone not ready to swap out their toilet, a smart bidet seat is the easiest entry point. For full-feature experience and aesthetics, a smart toilet is the better long-term answer.
Size, Shape, and Rough-In Measurements
Before buying, measure the rough-in: the distance from the wall behind the toilet to the center of the floor drain. Most US homes have a 12 inch rough-in, while older homes often run 10 inches. Smart toilets like the Loupusuo and EPLO models fit the 12 inch standard. For a 10 inch rough-in, you may need to special-order or choose a different model.
Bowl shape matters for comfort. Elongated bowls (like the TOTO C5 and HOROW T38) offer more front-to-back clearance. Round bowls (like the Loupusuo) save space in tight bathrooms.
Electrical and Plumbing Requirements
Every smart toilet needs a GFCI outlet within reach of the included power cord, typically 3 to 4 feet. If your bathroom lacks a GFCI, an electrician typically charges $200 to $500 for the install, depending on the panel access and wall material. The water supply line is standard 3/8 inch compression fitting. Tankless models like the Loniko ST945B require 20 to 80 PSI household pressure for reliable flushing.
Key Features to Compare
The most useful smart toilet features are: heated seat, integrated bidet with adjustable water pressure and temperature, warm-air dryer, automatic flush, automatic lid, deodorizer, night light, pre-mist or pre-wet bowl, self-cleaning wand, foam shield, and a remote or app control. Voice assistants like Alexa and Google Home are emerging in the premium tier but still rare in mid-range models.
Cost-of-Ownership Estimate
A typical US household spends roughly $240 per year on toilet paper. Switching to a bidet toilet can cut that by 60 to 75 percent, saving $150 to $180 each year, or about $750 over five years. Add roughly $20 per year in electricity for the heated seat and warm water heater, and the net savings still land near $700 across five years for a four-person household.
Installation and Lifetime Cost
DIY installation runs 60 to 120 minutes for a competent homeowner. Plan for a plumber if your home needs flange replacement or rough-in adjustment, which adds $150 to $400. An electrician adds another $200 to $500 for a GFCI outlet. Across 8 to 12 years of typical lifespan, the smart toilet clears its cost gap versus a standard toilet plus a lifetime of toilet paper.
Frequently Asked Questions
Are smart toilets worth the money?
Yes, smart toilets are worth the money for households that value hygiene, comfort, and accessibility. A mid-range smart toilet in the $500 to $1,500 range pays back its higher up-front cost within 3 to 5 years through reduced toilet paper use (typically $150 to $180 saved per year). Households with elderly family members, mobility limitations, or anyone who values hands-free operation benefit most. Pure cost-focused buyers may find a basic bidet seat a smarter entry point.
What does a smart toilet actually do?
A smart toilet combines an integrated bidet, heated seat, warm-air dryer, automatic flush, deodorizer, and night light in a single fixture. Higher-end models add auto open or close lid, foam shield splash control, pre-mist bowl wetting, UV wand sterilization, and remote or app control. The functions are designed to improve hygiene, reduce toilet paper use, and remove the need to touch the toilet during a visit.
Do you still wipe when you use a bidet?
You do not need to wipe after using a smart toilet bidet in most cases. The warm water spray cleanses the area thoroughly and the warm-air dryer finishes the job. Many users keep a small amount of toilet paper for occasional dabbing during the first week while adjusting to the new routine. Within a month, most households cut toilet paper use by 60 to 75 percent.
Do smart toilets need electricity?
Yes, every smart toilet needs electricity to run the heated seat, water heater, bidet wand, deodorizer, auto flush, and night light. The cord plugs into a standard GFCI outlet, which is required for any bathroom receptacle. During a power outage, most smart toilets include a manual or battery backup flush for short-term outages. Extended blackouts will disable the bidet and heated seat until power returns.
What toilet do most plumbers recommend?
Plumbers consistently recommend TOTO for reliability, longevity, and parts availability. Among mid-range brands, EPLO, Loupusuo, and HOROW earn positive feedback from plumbers familiar with their build quality and US-based support. Kohler remains a strong premium choice.

Can a smart toilet flush during a power outage?
Most smart toilets can flush during a power outage using a built-in battery backup or a manual override button. The EPLO iX7 PRO, Loupusuo L08 Pro Max, CANEST TC-100GE, and HOROW T38 all include backup flush functions. The bidet, heated seat, and deodorizer stop working until power returns, but the basic flush function is preserved for emergency use across multi-day outages on some models.
Final Verdict
Our editor’s choice for the best smart toilet in 2026 is the TOTO WASHLET C5, a time-tested bidet seat with more than 4,000 verified reviews and TOTO’s signature reliability. For shoppers wanting a full one-piece smart toilet, the Loupusuo L08 Pro Max delivers the best overall value, while the WOODBRIDGE B0930S Foam Shield leads the premium category with a 1000g MaP flush and ADA comfort height. The EPLO U8MAX earns top rated status for its four-season temperature sensing, the EPLO iX7 PRO shines in low-pressure homes with its booster pump, and the HOROW T38 covers tight bathrooms with a built-in tank and pump. The Loniko ST945B is the budget pick for shoppers wanting a tankless design under $400, and the CANEST TC-100GE is the friendliest first smart toilet for new owners.
Whichever model you pick, plan for a 60 to 120 minute DIY install or budget $300 to $800 for a professional plumber plus electrician if your bathroom needs a GFCI added. Within a year, the toilet paper savings alone will cover the difference between a smart toilet and a standard model for most households.
