A smart toilet sounds like a gadget until the first cold morning you sit on a heated seat and realize you’re never going back. The 2026 lineup has quietly matured: the seat warms, the lid opens as you walk up, a warm-water bidet wand replaces the paper, a dryer finishes the job, and the whole thing flushes itself when you leave. The luxury features that used to cost $5,000 from a single Japanese brand now start under $600 from a dozen of them.
The catch is that “smart toilet” covers two very different things. Some are integrated units — the toilet and the bidet seat are engineered as one piece, which looks cleaner and packs in features like auto-open lids, night lights, and self-cleaning wands. Others are a standard toilet plus a separate smart bidet seat bolted on, which is cheaper and easier to retrofit. This guide is about the first kind — fully integrated smart toilets you install as a single fixture.
We back-engineered this list from units in stock on Amazon right now, verified every model against its live product page, and spread the picks from a genuinely affordable $500 tankless unit up to a $3,000 TOTO. Six smart toilets, six different budgets and priorities. No discontinued models, no phantom listings.
How We Picked
Smart toilet spec sheets are a soup of acronyms, and “smart” gets stretched thin. We filtered for four things that actually matter day to day:
- Real smart features that work without fuss — heated seat, warm-water bidet wash, auto or foot-sensor flush, and a remote or side panel that isn’t cryptic. Bonus points for auto-open lids and self-cleaning nozzles.
- Flush performance you can trust — a strong MaP (Maximum Performance) score and, for tankless units, a booster pump that handles low or inconsistent water pressure. A smart toilet that clogs is just an expensive problem.
- Verified, live Amazon listing with the correct brand and model on the product page — checked the day this guide was written.
- A real spread of budgets so there’s a pick whether you want the cheapest unit that still feels luxurious or a TOTO that will outlast the house.
Our Top Smart Toilet Picks
WOODBRIDGE B0970S Tankless Smart Bidet Toilet — Best Overall
If you want one smart toilet that gets everything right without the TOTO price tag, the WOODBRIDGE B0970S is the one to beat. It’s the model that shows up on nearly every smart toilet shortlist for a reason: it’s a genuinely complete integrated unit at a mid-range price, and WOODBRIDGE has enough of a track record that parts and support actually exist when you need them.
It’s a tankless design, which means it pulls water straight from your supply line through a built-in booster pump instead of refilling a tank. That gives you unlimited consecutive flushes (handy for a busy bathroom) and a lower, cleaner one-piece profile with no tank to wipe around. The pump also compensates for weaker household water pressure, so the flush stays strong.
The smart features are the full set: a heated seat with adjustable temperature, a self-cleaning warm-water bidet wand with posterior, feminine, and pulsating modes, warm-air drying, and auto deodorization. Flushing is genuinely hands-free — off-seat auto flush, a foot-sensor kick, a button, or the remote. The ADA-compliant chair height makes it easier to sit and stand, which matters more than you’d think for a fixture you use every day for a decade.
Why it’s our top pick: It nails every core smart feature, flushes hard thanks to the booster pump, and costs a fraction of the premium brands — the sweet spot of the category.
Pros:
- Tankless with booster pump — strong flush, unlimited consecutive flushes
- Full feature set: heated seat, warm-water bidet, dryer, deodorizer
- Four hands-free flush methods including foot sensor
- ADA comfort height
- Trusted brand with real support and parts
Cons:
- Tankless units need a nearby GFCI outlet and decent water pressure
- Heavier install than a bidet-seat retrofit
- Remote has a learning curve the first week
EPLO E16 Tankless Smart Toilet — Best Budget
The EPLO E16 is proof that “budget smart toilet” is no longer an oxymoron. For around $500 you get a one-piece tankless unit with the features that used to live only in the premium tier: a heated seat, warm-water bidet washing, dual auto flush, a foot-sensor flush, and an LED display that shows you what the toilet is doing.
It’s also the lightest unit here at around 83 pounds, which sounds like a footnote until you’re wrestling a toilet up a flight of stairs during install. The smaller footprint makes it a smart choice for a powder room or a compact bathroom where a bulkier unit would crowd the space. The dual-flush system runs 1.6 GPF for solids and 1.1 GPF for liquids, so you’re not wasting water on every flush.
You give up some polish compared to the WOODBRIDGE and the TOTOs — the build feels a touch lighter, and EPLO is a younger brand without decades of plumbing pedigree. But the day-to-day experience of a warm seat, a warm-water wash, and a touchless flush is fully intact. If the only thing keeping you out of a smart toilet is the price, this is the on-ramp.
Why it earned the budget pick: It delivers the genuinely useful smart features — heated seat, warm bidet, auto flush — for the lowest price here, in the easiest unit to install.
Pros:
- Lowest price of any full smart toilet in this guide
- Lightest and most compact — great for small bathrooms
- Heated seat, warm-water bidet, dual auto flush, foot sensor
- LED display shows status at a glance
- Water-saving 1.6 / 1.1 GPF dual flush
Cons:
- Build quality is a step behind the premium brands
- Younger brand with a shorter support track record
- Tankless — needs a GFCI outlet and adequate water pressure
HOROW T39 Luxury Smart Toilet — Best Value
The HOROW T39 sits in the sweet spot between the bargain EPLO and the mainstream WOODBRIDGE, and it throws in a few extras that punch above its price. HOROW has become one of the most reliable value brands in this category, and the T39 is their well-rounded modern pick for a bathroom remodel.
What stands out is the feature-per-dollar ratio. You get a heated seat, instant warm water (heated on demand rather than stored in a small tank, so it doesn’t run cold mid-wash), an auto open/close lid, a night light for 3 a.m. trips, and a smart display built into the unit. HOROW also added an anti-splatter foam shield — a spritz of foam that lands in the bowl before you do, cutting down splashback and making the bowl easier to keep clean.
It’s ADA chair height, elongated for comfort, and styled to look like a much more expensive fixture. For anyone who wants the “walks in, lid opens, warm seat, warm wash, self-flush” experience without stepping up to four figures, the T39 is the value play.
Why it earned the value pick: Instant warm water, auto lid, night light, and a foam shield at a price closer to the budget tier than the premium one.
Pros:
- Instant on-demand warm water (no cold mid-wash)
- Auto open/close lid and built-in night light
- Anti-splatter foam shield keeps the bowl cleaner
- Smart display and ADA comfort height
- Strong feature set for the money
Cons:
- Tank-style unit is bulkier than the tankless picks
- Foam shield needs occasional refilling
- Fewer bidet spray customizations than the TOTOs
HOROW T05S Smart Toilet with Bidet — Best for Low Water Pressure
Low or inconsistent water pressure is the quiet killer of smart toilets — a lot of tankless units simply won’t flush well below a certain PSI, and buyers find out the hard way after install. The HOROW T05S Smart Toilet with Bidet is built specifically for that problem. It pairs a water tank with a built-in booster pump, so it stores water and pressurizes the flush regardless of what your household supply is doing.
If you’re in an older home, a high floor of an apartment, a rural property on a well, or anywhere the shower goes weak when someone runs the sink, this is the pick that won’t leave you double-flushing. Beyond the pump, it’s a complete smart toilet: instant warm water, a heated seat, an auto open/close lid, and automatic flushing. It’s an elongated, comfortable unit that looks the part of a remodel centerpiece.
Because it keeps a tank, it’s less minimalist than the tankless WOODBRIDGE or EPLO, but that tank is exactly what makes the flush dependable when your pressure isn’t. For a lot of homes, that reliability is worth more than a slimmer silhouette.
Why it earned the low-pressure pick: The tank-plus-pump design guarantees a strong flush where pure tankless units struggle — the safest choice for older or low-pressure plumbing.
Pros:
- Tank + booster pump handles low or inconsistent water pressure
- Instant warm water and heated seat
- Auto open/close lid and automatic flush
- Reliable flush without depending on household PSI
- Comfortable elongated bowl
Cons:
- Tank design takes up more space
- Pump adds a faint mechanical sound on flush
- Heavier to move and install
TOTO WASHLET+ Nexus S7A One-Piece — Best Premium
TOTO invented this category, and the WASHLET+ Nexus S7A is where their engineering advantage becomes obvious. This is a one-piece elongated toilet paired with TOTO’s S7A washlet seat, and the difference from the value brands is in the details you feel every day: quieter operation, a more refined warm-water wash with genuinely useful spray adjustments, a heated seat that heats evenly, and an auto-open lid and auto flush that just work, trip after trip, year after year.
The standout is TOTO’s CEFIONTECT glaze — an ultra-smooth ceramic finish that keeps waste from sticking, so the bowl stays cleaner with less scrubbing and less water. Combined with the 1.28 GPF flush, it’s the rare premium toilet that’s also efficient. The WASHLET+ design routes the seat’s supply line and cord through the base for a clean, cordless-looking install with nothing dangling.
It’s a serious investment at around $2,600, and it’s overkill if you just want a warm seat. But if this is a forever bathroom and you want the fixture that defined the category — the one with the reliability reputation and the parts availability to match — the Nexus S7A is it.
Why it earned the premium pick: TOTO’s build quality, CEFIONTECT self-cleaning glaze, and refined washlet experience are a real step up from the value brands.
Pros:
- TOTO reliability and long-term parts support
- CEFIONTECT glaze keeps the bowl cleaner, uses less water
- Refined warm-water wash with real spray adjustments
- Auto-open lid and auto flush, cleanly integrated
- Efficient 1.28 GPF flush
Cons:
- Premium price — several times the value picks
- Overkill if you only care about a heated seat
- Professional install recommended
TOTO WASHLET G450 Integrated — Best Luxury
The TOTO WASHLET G450 is the fully integrated flagship — the toilet and washlet engineered as a single seamless unit rather than a seat added to a bowl. That integration is what you’re paying for: cleaner lines, fewer seams to trap grime, and TOTO’s most complete feature set in one fixture.
It uses instant (tankless) water heating, so the bidet delivers an endless stream of warm water instead of running cold once a small reservoir empties — a genuine upgrade if more than one person uses it back to back. The dual flush runs an ultra-efficient 1.0 or 0.8 GPF, among the lowest here, and it still clears the bowl thanks to TOTO’s flush engineering and CEFIONTECT glaze. You also get the full suite of auto open/close lid, auto flush, heated seat, warm-air dryer, and a multifunction remote with several spray settings.
This is the top of the range, and the price reflects it. But for a primary bathroom in a home you plan to keep, or a remodel where the toilet is meant to be a statement, the G450 is the integrated unit that does everything and hides the mechanics behind clean ceramic.
Why it earned the luxury pick: A seamless integrated design, endless instant-heated warm water, and the lowest flush volume here — TOTO’s most complete single-fixture smart toilet.
Pros:
- Fully integrated one-piece design — cleanest look, easiest to wipe down
- Instant water heating for endless warm-water washing
- Ultra-efficient 1.0 / 0.8 GPF dual flush
- Complete feature set: auto lid, auto flush, heated seat, dryer
- TOTO reliability and CEFIONTECT self-cleaning glaze
Cons:
- Highest price in this guide
- Integrated design means the whole unit is the repair unit
- Professional install strongly recommended

Buying Guide: How to Choose a Smart Toilet
Integrated Unit vs. Toilet + Bidet Seat
The first fork in the road. An integrated smart toilet (everything in this guide) is engineered as one fixture — cleaner looking, more features, but you replace the whole toilet. A standard toilet plus a smart bidet seat is far cheaper, installs in an afternoon, and lets you keep your existing bowl — but it looks bolted-on and has fewer bells and whistles. If you’re remodeling or the old toilet is on its way out, go integrated. If you just want a warm seat and a bidet on a budget, a seat is the smarter buy.
Tankless vs. Tank
Tankless units pull water straight from the supply line through a booster pump. Upsides: a slim one-piece look, unlimited consecutive flushes, and no tank to clean around. Downsides: they need adequate water pressure and a nearby GFCI outlet, and they won’t flush well if your pressure is weak. Tank units store and pressurize water, so they flush reliably regardless of household pressure — the safer pick for older homes, upper apartment floors, and wells. If your shower loses steam when someone runs the sink, buy a tank (or a tank-plus-pump unit like the HOROW).
Flush Power (MaP Score)
MaP (Maximum Performance) measures how much waste a toilet clears in a single flush, in grams. Anything at 800g or above is strong; 1,000g is excellent. A smart toilet that clogs constantly erases all the luxury, so don’t ignore this number to save a few dollars.
Warm Water: Tank vs. Instant
Cheaper units heat a small reservoir of water; once it empties, the wash runs cold until it refills. Instant (tankless) water heating warms water on demand for an endless supply — noticeably better if more than one person uses the toilet in a row. It’s worth prioritizing if your budget allows.
The Practical Stuff
- You need a GFCI outlet near the toilet. Smart toilets are electric. If there isn’t one, budget for an electrician.
- Measure your rough-in — the distance from the wall to the center of the drain, usually 12 inches. Buy to match.
- Water pressure matters for tankless units. If yours is low or variable, choose a tank or tank-plus-pump model.
- Bidet users save on paper — a real, ongoing cost offset that adds up over the years. Pair it with a smart faucet and smart water-leak detection and your bathroom is genuinely covered.
Frequently Asked Questions
Do smart toilets need electricity? Yes. Every integrated smart toilet needs a nearby GFCI outlet to run the heated seat, warm-water bidet, dryer, and auto features. If your bathroom doesn’t have an outlet by the toilet, factor in an electrician before you buy.
What happens during a power outage? Most models include a manual or mechanical flush option so you can still flush without power. Tank units with a booster pump generally hold an advantage here. Check the specific model’s blackout-flush feature — several in this guide advertise it directly.
Are tankless smart toilets reliable with low water pressure? Not always. Pure tankless units depend on your household water pressure to flush well. If your pressure is low or inconsistent, choose a tank model or a tank-plus-pump unit like the HOROW T05S Smart Toilet with Bidet, which pressurizes the flush on its own.
Is a smart toilet the same as a bidet? Not quite. A bidet is one feature — warm-water washing — that smart toilets include alongside heated seats, auto flush, dryers, and auto-open lids. You can also get that bidet function alone with a smart bidet seat on your existing toilet, for much less money.
How hard is a smart toilet to install? A tankless integrated unit is a bit more involved than a standard toilet because of the electrical and water-pressure requirements, but it’s a doable DIY job for a confident homeowner with a GFCI outlet already in place. For the premium TOTO units, professional installation is recommended to protect the warranty.
Do smart toilets really save water? The efficient ones do. Dual-flush models (1.0–1.28 GPF) and TOTO’s CEFIONTECT glaze use noticeably less water than an old 3.5+ GPF toilet, and the bidet function cuts paper use. Over years, the savings are real even if they won’t pay off the toilet by themselves.
Are the heated seat and warm water worth it? This is the feature nobody expects to care about and everybody ends up loving. A heated seat on a cold morning and a warm-water wash are the two things owners cite most. If you’re on the fence, they’re the reason to get off it.
Bottom Line
The WOODBRIDGE B0970S is the smart toilet most people should buy — a complete tankless unit with a booster pump, every core feature, and a mid-range price. If budget is the deciding factor, the EPLO E16 delivers the heated seat, warm bidet, and auto flush for the least money, and the HOROW T39 adds instant warm water and an auto lid for a little more.
If your home has weak or inconsistent water pressure, skip the pure tankless units and get the HOROW T05S Smart Toilet with Bidet — its tank-plus-pump design flushes reliably no matter what your plumbing is doing. And if this is a forever bathroom, the TOTO WASHLET+ Nexus S7A and the fully integrated TOTO G450 are the fixtures that defined the category, with the build quality, self-cleaning glaze, and parts support to last decades.
Match the flush type to your water pressure, make sure you’ve got a GFCI outlet, and buy the tier that fits your bathroom. Once you’ve lived with a warm seat and a self-flushing bowl, the old toilet feels like a relic.
