This high-tech commode will blow you away with its list of features, but we’ve rounded up a handful of comparable models as well. We have also put together a buying guide to help you choose the right model for your home.

6 Best Smart Toilets Reviewed

Choosing a new toilet for your home is important, from comfort to water conservation.

Smart toilets are no different, and below you’ll find six of the best smart toilets available, including budget-friendly toilets along with premium porcelain thrones.

The Best Smart Toilet Overall

  • Dual-zone bidet
  • Automatic lid
  • Warm air dryer
  • Stainless-steel bidet wand
  • Touchscreen remote control
  • Auto flush
  • Deodorization system


  • Single-flush system

The KOHLER Karing 2.0 stands out from other smart toilets with its smooth design. It’s also the best toilet overall when you’re looking for the perfect balance of price, performance, and quality you can trust.

This skirted toilet has a tankless design that makes cleaning an absolute breeze. It has an elongated bowl for additional comfort, and you’ll never have to dirty your hands by opening or closing the lid.

The heated seat is adjustable, while odors are made a thing of the past with an automatic deodorizer. The Karing 2.0 has a bidet function with a self-cleaning wand like most smart toilets.

This wand is made from stainless steel, however. Its self-cleaning system uses a combination of UV light and sterilized water to sanitize the bowl.

The bidet’s front and rear wash features are adjustable, and the bowl is lightly misted before each use. It also has a night light, warm air dryer, and comes with a touchscreen remote control.

While it has plenty of features, it is only a single-flush toilet. It has a rating of 1.08 GPF using the Power Lite Flushing system.

2. TOTO G400 Tornado Flush Smart Toilet

A Smart Toilet with a Powerful Flush

  • Automatic toilet seat
  • Dual-Max flush system
  • Memory setting
  • Multiple settings for water pressure
  • Adjustable heated seat
  • Deodorizer


  • Could have difficulty installing
  • Tech support

TOTO has produced more smart toilets than most manufacturers, and their Washlet series has proved popular with consumers across the globe. The G400 is our top choice from the company and a powerful toilet with plenty of brains.

The TOTO G400 is one of the more automated alternatives on our list. It will automatically flush itself when you rise from the bowl through the company’s Dual-Max flushing system.

It determines how much water is needed and will choose between 1.28 GPF for solids or 0.9 GPF for liquid waste. An ionized charcoal air filter will help cleanse the air while the bidet system cleans your undercarriage.

You can choose from front, rear, or soft rear wash with adjustable water pressure. The heated seat will automatically open or close, and the system will clean the wand and bowl with each use.

It’s hard to find a fault with the TOTO G400 washlet, and homeowners largely agree. The skirted shape is easy on the eyes and has just as many features as our top choice. On the downside, some felt the customer support was lacking and thought it was challenging to install.

3. Swiss Madison Well Made Avancer Tankless Smart Toilet 

A Stylish Smart Toilet from Swiss Madison

Best Smart Toilets  5Best Smart Toilets  6


  • Integrated Bidet
  • Vortex dual-flush at 1.1/1.6 GPF
  • Heated seat
  • Hands-free flushing
  • Night light
  • Remote control


  • Not quite as smart as other toilets
  • 1-year warranty

One of the newer toilets to make our list comes from Swiss Madison Well Made. The Avancer is one of the more affordable smart toilets available to homeowners and geared towards water consumption as well.

This one-piece toilet has a similar design to other smart commodes, so it’s tankless with an elongated bowl. While the lid will not automatically open or close, it will flush itself.

The Avancer can lightly rinse and flush while you’re sitting, but that isn’t the only noteworthy feature of this dual-flush toilet.

The soft-closing toilet seat is heated with six temperature levels that extend to the bidet itself. The spray is adjustable for men and women.

A self-cleaning wand, LED night lights, and air drying system round things out on the Swiss Madison Well Made Avancer SM-ST060.

Swiss Madison put a lot of thought into the design of this smart toilet. It may not have as many features as Neorest or Karing, but it’s considerably cheaper. Reviews are still light on this model, however, as it’s one of the newest models in their catalog.

4. TOTO Neorest 700H Smart Toilet 

The Best Smart Toilet for Water Conservation

Best Smart Toilets  7Best Smart Toilets  8


  • Front, rear, and soft washlet settings
  • Automatic lid
  • Heated seat
  • Hands-free automatic flush
  • Air purifier
  • Remote control & Timer


  • The automatic lid can be too sensitive
  • The price tag

Whereas some toilet manufacturers have a few smart toilets in their catalog, TOTO has a collection. The TOTO Neorest 700H is designed for water conservation and a commode packed full of high-tech features.

The Neorest 700H is coated in the company’s CEFIONTECT ceramic glaze, while the one-piece design takes up a minimal amount of space. It’s ADA compliant with the toilet seat attached but is shorter than some models with a bowl height of 15 9/16” from floor to rim.

Waste is effectively removed from the toilet thanks to their Tornado Flush siphon jet system. It’s also one of the most efficient smart toilets on the market, with 0.8 and 1 gallon per flush.

You don’t have to use a lever, as this toilet will automatically flush itself when you leave the commode.

TOTO covered all the bases with this smart toilet from the EWATER+ system that uses electrolyzed water to clean the bowl to the deodorizer. Homeowners love the features, although some felt the lid sensor was too sensitive.

5. American Standard Cadet Touchless Toilet 2989709.020

A Smart and Simple Toilet From American Standard

Best Smart Toilets  9Best Smart Toilets  10


  • Chair height with elongated bowl
  • Automatic flushing sensor
  • Soft-close toilet seat
  • EverClean surface
  • Excellent warranty


  • Requires batteries for the flap sensor

Most major toilet manufacturers have broken into the world of smart toilets. American Standard doesn’t have as many models as the competition, but the Cadet Touchless is an interesting alternative to brainier commodes.

This toilet has a traditional yet updated style with a two-piece design and soft close toilet seat. There’s a lid and tank at the top, along with a manual flush button on the side.

What makes this commode smart is an auto-flush sensor that homeowners can place within 3 feet of the toilet.

American Standard used a concealed trapway on this model, making it easy to clean. It’s a single flush toilet with a rating of 1.28 GPF and a 3-inch flush valve. This chair-height smart toilet comes with a slow-close lid and sports a MaP score of 1,000.

This two-piece toilet may not be the flashiest or have the most features, but it’s well-built and a more intelligent toilet than your typical commode.

We couldn’t find any significant drawbacks, although the battery-based flap sensor may be an issue for some.

6. WOODBRIDGE B0970S Smart Bidet Toilet

The Best Budget Smart Toilet

Best Smart Toilets  11Best Smart Toilets  12


  • Dual-flush system
  • Elongated one-piece design
  • Heated seat & LED night lights
  • Warm air dryer
  • Automatically flushes
  • Deodorizer


  • 1-year warranty
  • Installation could be challenging

When shopping for the best smart toilet, things can escalate quickly if you don’t keep your budget in mind.

The WOODBRIDGE B0990S is geared towards homeowners that don’t want to spend thousands and has an impressive list of smart toilet features for the price.

The first feature we want to highlight on the B0990S is the flushing system. It’s dual-flush with a rating of 1.0 or 1.6 gallons per flush, that’s built for low water pressure.

An ionized carbon filter takes care of odors, and the toilet will flush soon after you depart from it.

Posterior and feminine wash are available through the bidet, while a current of warm air will keep you dry. The air is adjustable, like the contoured heated seat on the WOODBRIDGE B09990S.

Other features to note include auto-flushing, foot sensor, and a night light.

This smart toilet is comfort height, and while it bears a striking resemblance to similar models, it has a more palatable price tag.

The automatic dual-flush system and other features bring a lot of value to the table, although it has a short warranty and some consumers felt it was challenging to install.

How to Find the Best Smart Toilet

Smart toilets are fairly new on the scene but have seen a surge in popularity because of their hands-free features. If you’re considering upgrading to a smart toilet, there’s more to consider than the style or trapway size.

Traditional Toilet Features

Before we get into what makes a toilet “smart,” we’re going to talk about a few features that should be important to every homeowner looking for a new toilet.

Dual-Flush Toilets

A dual-flush toilet offers a distinct advantage over a single-flush toilet. They save water by letting you choose a flush for solid or liquid waste, and while it raises the price, it’s well worth it if you want to conserve water.

Gallons per Flush

Another water-saving metric to keep an eye on is GPF which stands for gallons per flush. This tells you how much water a toilet uses every time it’s flushed. To meet WaterSense standards, a toilet must have a rating of 1.28 GPF or less.

Bowl Height

If you find a toilet uncomfortable to sit on, bowl height could be the issue. A comfort or chair height toilet measures around 16.5 inches or higher with the toilet seat included. A standard toilet is typically 14.5 to 15 inches by comparison.

Toilet Style

Toilets can come in different shapes and sizes, but all are either one or two-piece by design. Two-piece toilets have a separate bowl and tank, while one-piece toilets are easier to clean. A one-piece toilet can be more expensive, but they are less prone to leaks. 

Intelligent Toilet Features

The areas we touched on are key with any type of toilet whether it’s a luxury smart toilet with an air dryer or traditional model. When you start looking into smart toilet brands all the features are important.

With that in mind, we’re going to discuss the most popular features found on intelligent toilets from the automatic flush system to heated seats and self-cleaning toilet bowls. 

Smart Toilet Seats

The first feature most homeowners think of when it comes to intelligent toilets are the seat. Heated seats are relatively common in this class, but the best smart toilet can have seats that will do more than that.

If you want a truly hand-free toilet, look for one with an automatic lid. They will automatically open as you approach and quietly close as you step away. Some only open the lid, however, whereas models automate the entire toilet seat.

Heated seat functions vary, but some of the top models have multiple settings. It’s a good idea to check on those beforehand, along with the time it takes for the system to actually open the toilet seat.

Hands-Free Flushing

The other feature that can help make your time in the bathroom hands-free is how the intelligent toilet flushes.

A smart toilet can handle the waste automatically, although they can do this in different ways.

A budget-friendly smart toilet may come with physical sensors that work in conjunction with the toilet. High-end models will have that feature built-in, but you’ll want an alternative flushing method for any automated system.

All of the best smart toilets with automatic flushing provide a battery-based backup in case of power failure. Some also flush at intervals while you are on the throne to keep things tidy until you’re finished. You can even find a smart toilet bowl with a remote control.


We’ve seen a number of homeowners turn towards bidet toilet seats for commodes in the past several years. Well, many smart toilets have built-in bidets with some very surprising features.

When looking for a smart toilet with a bidet toilet seat, check how many zones it covers. Two are standard and provide coverage to the front and read. A few models have three zones, and most have more than one mode.

Whether you prefer a gentle spray on your bottom or one that oscillates, consider the modes along with the total coverage. A great smart toilet will allow you to adjust the spray and angle.

Warm air dryer features are standard on most of these models as well.

Self-Cleaning Smart Toilets

Nobody likes cleaning a toilet bowl, regardless of new chemicals or tools that make things relatively simple. A self-cleaning smart toilet can take care of that for you through several different methods.

The most common way smart toilets clean themselves is with a pre-spray. The bowl is misted before use, which makes waste removal easier. The water itself may be treated or electrolyzed with a system inside an intelligent toilet.

Keeping the bowl tidy is a definite bonus, but it’s also important to consider the bidet wand itself. You can even find stainless steel wands and UV sterilization on a handful of premium models.

Air Purifying Smart Toilets

There have been thousands of jokes made about foul odors coming from bathrooms, even if air fresheners have helped in that regard. Consider a smart toilet with built-in air purification if you don’t want your bathroom smelling like a bouquet of flowers.

Activated carbon is the most popular type of filter used in smart toilets today. They will help clean the air quickly when activated, but you should check on the cost and availability of refills beforehand.

Smart Toilet Installation

It doesn’t matter if you’re buying the best one-piece toilet or one designed to remain clog-free. An improperly installed toilet can lead to significant issues in your bathroom and a large repair bill.

Many smart toilets are tankless compared to one or two-piece toilets that have a traditional tank on top.

These systems actually have water in the bottom and are entirely different to install than a conventional commode. With any smart toilet, pay attention to the rough-in sizes and how it’s powered as well.

Several models on our list require a GFI outlet to function. While those are standard in many new homes, the length to the outlet is critical, along with cord placement.

Replacement Parts and Customer Support

It’s not uncommon for homeowners to occasionally replace flappers and other parts inside the toilet tank. Those parts are easy to acquire, but things aren’t as simple when you have a smart toilet.

Components like a warm air dryer and the automatic flushing system are a little harder for homeowners to address.

Even simple parts like the toilet seat can be tricky to acquire and install. That’s where a good warranty comes into play, along with customer support.

You can easily find warranty information on every toilet from our list, but tech support can be hit or miss.

We found that companies like KOHLER and American Standard excel in that department while others can prove difficult to work with.

Don’t underestimate the importance of tech support or a solid warranty with a smart.

Our Verdict

As you can see, the selection of smart toilets is relatively small compared to a standard commode. While we chose something for everyone, we felt the KOHLER Karing 2.0 gives homeowners the best bang for their buck.

This high-end toilet has every feature you could imagine, although the Swiss Madison Well Made Avancer provides many of those smart toilet features at a fraction of the price.

What’s considered a good warranty for a smart toilet?

In our research, we found that most companies only provide a 1-year guarantee on components within the toilet. Top manufacturers can have tiered warranties ranging from 3-4 years, however.

Are smart toilets challenging to install?

Compared to a traditional toilet, they can be. They don’t need to be wired by an electrician, but it’s a good idea to call in a professional for a high-tech tankless design.

Do you need to use special toilet paper with a smart toilet?

Unless otherwise specified, you can use toilet paper in intelligent toilets just like a standard commode.

Will a smart toilet use a lot of electricity?

Any fixture that requires electricity to run will increase your electric bill to a degree, but the top smart toilets are energy efficient and save money on your water bill.
