Best Bidet Toilet Combo: Top Smart Toilets for 2026

A bidet toilet combo puts the bidet inside the toilet instead of on top of it. Rather than bolting a seat onto your existing bowl, you replace the whole fixture with a single integrated smart toilet that already has a warm-water wash, heated seat, warm air dryer, and usually a hands-free auto flush. The result looks like a purpose-built modern toilet, not a toilet wearing an attachment, and it is the most seamless way to own a bidet.

That seamlessness comes at a price. Where a good bidet seat or attachment runs $30 to $700, integrated smart toilets start around $900 and climb to nearly $9,000. So the real question is not whether they are nice (they are), but which one gives you the features you will actually use without paying for engineering and brand cachet you will not.

We compared the top integrated smart toilets across wash performance, comfort features, flush and hygiene technology, installation demands, and total cost. Here are our picks at every price point.

Best Overall Value: WOODBRIDGE B0970S

Price: ~$900 | Type: Tankless one-piece smart toilet | Fits: N/A (complete unit)

The WOODBRIDGE B0970S earns our top spot because it delivers almost the entire integrated smart-toilet experience for around $900, which is less than many premium bidet seats cost on their own. You get a heated seat, warm-water wash, warm air dryer, and hands-free foot-sensor auto flush in a clean one-piece design.

Its standout engineering choice is the tankless, booster-pump flush. The B0970S pulls water directly from your supply line and heats it on demand, so warm water never runs out and the unit stays slim. The built-in booster pump keeps flush power strong even on homes with low or inconsistent water pressure, which is exactly where cheaper tankless toilets struggle. The ADA chair height (17.3 inches to the seat) also makes it easier to sit down on and stand up from, a real benefit for taller users and anyone with mobility concerns. If accessibility is a priority, our best bidet for seniors guide covers that angle in more depth.

Key specs (per manufacturer):

• Tankless, on-demand warm water with booster-pump flush
• Hands-free foot-sensor auto flush plus button and remote flushing
• Heated seat, warm air dryer, and adjustable warm-water wash
• Self-cleaning nozzle with posterior, feminine, and pulsating modes
• ADA chair height (17.3 in to the seat), elongated one-piece
• Multi-function remote with adjustable pressure, temperature, and position
• Requires a GFCI outlet

Who it is best for: Anyone who wants a real integrated smart toilet without a luxury price, and homes with weak or variable water pressure that need the booster pump.

The tradeoff: The booster pump is audible during the flush, and WOODBRIDGE does not have the decades-long service network of TOTO or Kohler. You still need a nearby GFCI outlet.

Best Mid-Range: OVE Decors Ella

Price: ~$1,250 | Type: Tank one-piece smart toilet | Fits: N/A (complete unit)

If you want a slightly more polished unit from a brand you can find at Home Depot, Costco, and Amazon, the OVE Decors Ella is the sweet spot. It keeps a built-in tank rather than going fully tankless, which means it flushes reliably at any water pressure without a booster pump. Instant heating still gives you warm water that does not run dry mid-wash.

The Ella covers all the daily-use features (heated seat, warm-water wash, warm air dryer, auto flush, night light, soft-close lid) and adds two hygiene touches you usually see higher up the price ladder: UV sterilization and a pre-mist that wets the bowl before use so waste is less likely to stick. Dual flush at 0.92 and 1.28 gallons keeps water use in check. It is a well-rounded, unfussy pick for a modern remodel.

Key specs (per manufacturer):

• Built-in tank, instant warm-water heating
• Auto dual flush (0.92 / 1.28 GPF), hands-free
• Heated seat, warm air dryer, soft-close lid, night light
• UV sterilization and pre-mist bowl protection
• Elongated one-piece, 15.75 in bowl height
• Multi-function remote
• Requires a GFCI outlet

Who it is best for: Buyers who want a familiar retail brand, reliable flushing at any water pressure, and UV hygiene features at a mid-range price.

The tradeoff: Wash pressure is gentler than the American Standard or a TOTO, and the remote interface is basic. The built-in tank makes it bulkier than a tankless unit.

Best from a Legacy Brand: American Standard Advanced Clean 100 SpaLet

Price: ~$3,400 | Type: Integrated bidet toilet | Fits: N/A (complete unit)

American Standard has been making toilets in the United States for well over a century, and the Advanced Clean 100 SpaLet is where that experience shows up in an integrated bidet toilet. It is a step up in both cleansing power and automation from the value picks.

The cleansing system uses dual self-cleaning nozzles with five position settings, directing warm water independently to front and rear. The heated seat offers five settings (three presets plus two you can save), and the warm air dryer runs at three temperatures. An auto-open/close lid greets you on approach, auto flush handles the rest, and AirShield blue light plus automatic deodorization keep the air fresh. Everything runs from a multi-function remote. It is a genuinely premium experience backed by a brand your plumber already knows.

Key specs (per manufacturer):

• Dual self-cleaning nozzles with five position settings
• Heated seat with five settings; warm air dryer with three temperatures
• Instant warm water
• Auto-open/close lid and auto flush
• AirShield blue light and automatic deodorization, soft night light
• Auto dual flush (1.32 / 0.92 GPF)
• Requires a GFCI outlet

Who it is best for: Buyers who want an established American plumbing brand, dual front-and-rear cleansing, and full lid-and-flush automation without going into Kohler or TOTO territory.

The tradeoff: It costs several times more than the WOODBRIDGE, and pricing swings widely between retailers, so it pays to shop around. Professional installation is recommended.

Best Smart-Home Tech: Kohler Numi 2.0

Price: ~$7,000 | Type: Integrated smart toilet | Fits: N/A (complete unit)

The Kohler Numi 2.0 is what you buy when the toilet is part of your smart home, not just your bathroom. Amazon Alexa is built in, so you can control features (and ask Alexa the usual questions) by voice. Add a built-in speaker system, ambient surround lighting that glows around the base, a touchscreen remote, and control through the KOHLER Konnect app, and it is as much a gadget as a fixture.

None of that would matter if the fundamentals were weak, but they are not. Touchless motion opens the lid, seat, and flush; the heated seat and a foot warmer keep you comfortable; and the warm-water bidet and warm air dryer do the core work. A pre-use bowl mist plus UV and electrolyzed-water wand cleaning handle hygiene, and an emergency flush works during a power outage. The angular, cubist design is unmistakable. Just know you are paying a large premium for the tech and the looks. For a sense of how Kohler-tier engineering stacks up against a great seat, our Neorest vs. Brondell Swash 1400 comparison frames the value gap well.

Key specs (per manufacturer):

• Built-in Amazon Alexa, speaker system, and KOHLER Konnect app control
• Ambient surround lighting; touchscreen remote
• Touchless lid, seat, and flush; heated seat and foot warmer
• Warm-water bidet and warm air dryer
• Pre-use bowl mist, UV and electrolyzed-water wand cleaning
• Dual flush (1.0 / 0.8 GPF), Comfort Height, emergency flush
• Requires a GFCI outlet; professional installation recommended

Who it is best for: Smart-home enthusiasts and anyone who wants a statement design piece with voice control and connected features.

The tradeoff: Around $7,000 for the white finish, and the connected features are more novelty than necessity. It is heavy and complex enough to warrant a professional install.

Best Luxury: TOTO Neorest NX1

Price: ~$8,766 | Type: Integrated smart toilet | Fits: N/A (complete unit)

The TOTO Neorest NX1 is the pinnacle of what a toilet can be. It does everything: the lid opens as you approach, four wash modes cover every need, and the Tornado Flush with CEFIONTECT glaze keeps the bowl spotless. PREMIST, eWATER+, and UV sanitization work together so the bowl and wand stay clean with almost no effort from you. The seamless one-piece form looks like modern sculpture.

Is it worth nearly $9,000? For most people, honestly, no. But if you are building or renovating and want the absolute best with zero compromises, nothing else matches TOTO's engineering. It is the toilet equivalent of a luxury car, where every detail is refined to the point that using it feels like an experience.

Key specs (per manufacturer):

• Auto-open/close lid with approach sensor
• Four wash modes with adjustable warm water
• Tornado Flush with dual flush (1.0 / 0.8 GPF)
• PREMIST, eWATER+, and UV sanitization
• Heated seat, warm air dryer, deodorizer
• CEFIONTECT ceramic glaze; 121 lbs, professional installation required
• Requires a GFCI outlet

Who it is best for: Homeowners doing a high-end renovation who want the ultimate integrated smart toilet with no compromises.

The tradeoff: The price is in a different universe, and at 121 pounds with integrated plumbing, professional installation is mandatory. Repairs are more complex and TOTO-specific.

Bidet Toilet Combo Comparison Table

Bidet Toilet Combo vs. Bidet Seat: Which Should You Buy?

This is the most important decision, and it comes down to how much you want to spend and whether you are ready to replace your toilet.

Buy an integrated smart toilet (this guide) if you are renovating or building, you want the cleanest possible look, and you value having the bidet, heated seat, dryer, and flush engineered as one unit. You will pay $900 and up, and you will remove and replace your existing toilet.

Buy a bidet seat or attachment instead if you rent, you want to spend far less, or you are happy with your current toilet. A heated electric bidet seat gives you warm water, a heated seat, and a dryer for $400 to $700 while keeping your existing bowl, and a basic bidet attachment adds cold or ambient-temperature washing for well under $100. For a full walk-through of every option, our how to choose a bidet guide breaks down seats, attachments, and combos side by side, and types of bidets explains the categories in plain language.

The short version: a bidet seat is the practical upgrade, and a bidet toilet combo is the premium one. Neither is wrong. They just fit different budgets and situations.

What to Look For in a Bidet Toilet Combo

Tankless vs. Tank

Tankless units heat water on demand and stay slim, but they lean on a booster pump to flush well, which is why the WOODBRIDGE B0970S includes one. Tank units like the OVE Decors Ella keep a reservoir that flushes reliably at any water pressure at the cost of a bulkier profile. If your home has weak water pressure, either a tank model or a tankless model with a booster pump is the safer choice.

Wash and Comfort Features

Every unit here has warm water, a heated seat, and a warm air dryer. The differences are in refinement: how many nozzle positions and pressure levels you get, how many heated-seat settings, and whether the dryer offers multiple temperatures. Higher-end units like the American Standard and TOTO give you more granular control.

Automation and Hygiene

Auto-open/close lids, auto flush, deodorizers, and self-cleaning systems reduce how much you touch and clean the toilet. Watch for UV sterilization, pre-mist, and electrolyzed-water cleaning (branded eWATER+ on TOTO), which keep the bowl and wand cleaner between uses.

Installation and Running Costs

Every integrated smart toilet needs a GFCI outlet within about 4 feet of the toilet. If yours does not have one, budget $150 to $300 for an electrician. Heavier units warrant professional installation. Running costs are modest, typically a few dollars a month in electricity, and our bidet cost guide breaks down the full picture of upfront and ongoing expenses.

How We Evaluated These Smart Toilets

We assessed each integrated smart toilet on five criteria:

1. Wash performance: Water pressure range, temperature consistency, and nozzle options
2. Comfort features: Heated seat settings, dryer temperatures, and seat height
3. Flush and hygiene tech: Flush reliability, water efficiency, and self-cleaning systems
4. Installation demands: Weight, outlet requirements, and DIY feasibility
5. Total cost of ownership: Purchase price plus outlet, installation, and running costs

We cross-referenced manufacturer specifications with verified owner feedback to validate claims about flush performance, warm water behavior, and long-term reliability.

The Bottom Line

For most buyers, the WOODBRIDGE B0970S at around $900 is the best bidet toilet combo. It delivers the core integrated smart-toilet experience, a heated seat, warm water, auto flush, and a warm air dryer, for less than many premium bidet seats, and its booster pump makes it a safe bet even on low water pressure.

Step up to the OVE Decors Ella if you want a familiar retail brand with UV hygiene at a mid-range price, or the American Standard Advanced Clean 100 SpaLet for legacy-brand engineering and dual-nozzle cleansing. And if budget is no object, the Kohler Numi 2.0 is the smart-home showpiece while the TOTO Neorest NX1 is simply the most advanced toilet you can buy.

Not ready to replace your toilet? Start with a heated bidet seat and get most of the benefit for a fraction of the cost.
