Woodbridge is a well-known brand when it comes to bathroom fittings and fixtures. As such, the Woodbridge T-0019 is also quite popular among users as one of the best dual-flush toilets available today. It is an efficient and sleek toilet that can be ideal for your bathroom.

Why Did We Like It?

When it comes to combining efficiency with looks, the Woodbridge T-0019 is hard to beat. Thanks to its sleek, one-piece design, it not only looks great but is also easy to clean and maintain. 

Additionally, this toilet has been designed to be convenient and easy to use. The height of the seat makes it comfortable for most adults. Furthermore, it has a soft closing seat with durable stainless steel hinges for long-time usage.

The powerful siphon flushing system makes this toilet incredibly silent while increasing water efficiency compared to conventional toilets. We also observed that this toilet does not suffer from clogging or leaks. Moreover, its WaterSense certification implies that you will be able to save a lot of water, which provides excellent value for money. 

What Could’ve Been Better?

Despite having a sleek and contemporary design, we found that this toilet weighs quite a lot. In fact, it is heavy enough to make the installation process a little inconvenient and tricky. So, if you are planning to install this toilet in your bathroom, you may need some extra hands to do so.


  • Easy to clean
  • Does not clog or leak
  • Very comfortable to sit on
  • Silent and powerful flushing operation


  • Relatively heavy

True to its reputation as a renowned manufacturer of quality bathroom products, the SM-1T254 St. Tropez is an excellent dual-flush toilet by Swiss Madison. This toilet features an appealing modern design while being efficient in saving water.

Why Did We Like It?

The SM-1T254 St. Tropez is one of the most water-efficient toilets in its class. Its dual flushing allows you to choose between partial or full flush which uses 0.8 gallons and 1.28 gallons of water, respectively. This is not only fiscally efficient but is also environmentally sustainable.

Its performance, however, is not compromised despite having low water usage. The dual tornado flush ensures excellent performance for both solid and liquid waste. In addition, the toilet seat is designed to be comfortable and easy to use. And, thanks to its seamless, skirted trapway, there will be no dirt trapped around the edges and corners.

As an added convenience, the soft-closing toilet seat is fully detachable, thanks to its quick-release matte chrome hinges. So, if you want to clean the toilet by yourself, you can do so with ease. 

What Could’ve Been Better?

Given its water efficiency and design, we can say that this toilet is a worthy option for your bathroom. However, you should keep in mind that it is difficult to install on your own. You will require professional help for its installation, which is not only inconvenient but will also cost a little extra.


  • Extremely water-efficient
  • Soft, comfortable seat design
  • Convenient detachable toilet seat
  • Easy to clean


  • Difficult to install

With a legacy of more than 140 years, the American Standard Brand is a trustworthy name in the domain of kitchenware and bathroom fittings. And the 2886.218.020 H2Option is a testament to the reliability of this brand. This dual flush toilet is WaterSense for high water efficiency.

Why Did We Like It?

It is an efficient dual flush toilet, thanks to the siphon jet bowl technology that can flush both solid and liquid wastes by using minimal water. The partial flush uses 0.92 gallons of water, while the full flush uses at most 1.28 gallons.

In addition, the PowerWash rims ensure that the toilet is adequately clean with each flush. This complements the Everclean surface, and together these features help to keep the bowl clean for a long time. We found this to be sanitary and very convenient, as we were not required to manually clean the bowl often.

Besides, it comes with a choice of a round or elongated bowl in 3 different color options, which makes it customizable. It is also quite comfortable, thanks to its 16-½ inch height, which is suitable for most adults. 

What Could’ve Been Better?

One major complaint that we have with this dual flush toilet is that it comes without a toilet seat. Surprisingly enough, the seat is sold separately, which means you will have to shell out extra cash for an essential component. So, besides increasing the cost of this product, this can be a cause for inconvenience.


  • Uses very little water
  • Comes in 3 different colors
  • Does not need to be cleaned often
  • Comfortable seat height


  • Toilet seat is not included but is sold separately

The HOROW brand is relatively underrated, considering that it makes some great bathroom and kitchen fittings. Consequently, the brand’s HWMT-8733 model is somewhat overlooked due to this aspect. This dual-flush toilet is extremely compact and efficient and is, therefore, a great option for small bathrooms.

Why Did We Like It?

The HWMT-8733 is an extremely compact dual-flush toilet that you can get for small bathrooms. It is a one-piece toilet with dimensions of 25 x 13.4 x 28.4 inches and is therefore much smaller than some of our previous options.

However, do not be fooled by its size, as it has an efficient and powerful performance. The siphon flushing system uses 0.8 to 1.28 gallons with every flush. In addition, the flush is rated to remove 500 grams of solid waste per use.

The toilet is pretty easy to install as well, thanks to its small size. Moreover, its seamless trapway and glazed porcelain help to keep it clean for a long time, thereby making it easy to maintain. It is also quite comfortable and comes with chrome-plated flush buttons. Furthermore, its lengthy five-year warranty provides excellent value for money. 

What Could’ve Been Better?

Overall, the HWMT-8733 is an excellent choice if you have got a small bathroom. However, this obviously implies that it is not a suitable choice for larger bathrooms. So, this toilet may seem out of place and inadequate for a few homes.


  • Easy to install
  • Does not require to be cleaned frequently
  • 5-year warranty coverage
  • Provides excellent value for money


  • Not suitable for large bathrooms

For this review, we have considered the 2887218.020, which is another high-quality dual-flush toilet from American Standard. It is a two-piece toilet that is WaterSense certified for being extremely water efficient. And it is quite reliable and comes with a lengthy warranty of 5 years.

Why Did We Like It?

This dual flush toilet features a unique siphon jet technology which, along with a PowerWash rim, provides powerful and efficient flushing. It uses 0.92 gallons to at most 1.28 gallons of water per flush, which makes it a noteworthy choice.

Moreover, it is incredibly comfortable thanks to its soft seats and convenient height of 16-½ inches. The seamless, glazed finish and the 2-inch wide glazed trapway ensure that there is no dirt collection in the edges and corners. 

What’s more, this toilet comes in 3 different colors, which means you can get the color that best suits your bathroom. You can also select between a round or elongated toilet front and two different heights based on your convenience. 

And lastly, the Chinaware body comes with a limited lifetime warranty, while other mechanical parts have a 5-year warranty. 

What Could’ve Been Better?

This is a two-piece toilet, which implies that installing it is relatively more complicated than one-piece toilets. Furthermore, you have to separately buy the toilet seat, as it is not included with the toilet itself, which can subsequently increase the price.


  • Comfortable toilet seat design
  • Remains dirt and stain-free for a long time
  • Comes in different colors, bowl shapes, and height
  • Requires minimal maintenance


  • Difficult to install

Kohler is a renowned international brand that is often considered to be one of the leading names in bathroom fittings and accessories. And the K-3987-0 Wellworth is an excellent dual flush toilet that is a part of the brand’s Wellworth line. It is a compact and efficient toilet that comes with a powerful flush.

Why Did We Like It?

The Kohler K-3987-0 Wellworth features an innovative class five flushing technology. It utilizes a gravity flush system to create a powerful siphon that delivers clean flushing without any clogging. All the while, it only uses 1.1 to 1.6 gallons per flush, which makes it a strong yet efficient dual-flushing toilet.

It also features a rounded front bowl and a compact design, which makes it suitable for smaller bathrooms. The glazed trapway ensures that the edges and corners are clean and leakproof. Furthermore, it is a traditionally designed two-piece toilet that comes with a left-hand nested trip lever.

Additionally, it comes in 3 color choices so that you can select the best one that suits your bathroom. All of this comes with an attractive price tag, which provides excellent value for money. 

What Could’ve Been Better?

Despite being a great dual flush toilet, it does not come with a toilet seat, which is one major drawback of the Kohler K-3987-0. However, thanks to its low price, buying a seat will not exceed your budget by much, so it is just a minor inconvenience.


  • Can be used in smaller bathrooms
  • Easy to install
  • Does not clog

  • Does not include a toilet seat

When speaking of convenience, this toilet is quite comfortable, thanks to its soft closing toilet seat and convenient seat height. The stainless steel seat hinges are durable, and you can easily unhinge them to remove the seat for periodic maintenance.  

What Could’ve Been Better?

This is a pretty good toilet for your bathroom, thanks to the convenience and efficiency that it offers. However, one minor inconvenience that we observed with this toilet is that it is pretty challenging to install. So, you will require additional assistance unless you have prior experience in installing such toilets.

  • Seamless porcelain one-piece with an easy-to-clean design.

Since it is one of the biggest names in the business, Swiss Madison toilets have become associated with premium style and superior performance. And therefore, we have reviewed the SM-1T106 Concorde, which not only has a sleek, modern flair but is also extremely efficient in its function.

Why Did We Like It?

The SM-1T106 Concorde is a WaterSense-certified toilet, which implies that it is incredibly judicious when it comes to water usage for flushing. Its high-performance gravity flush uses only 0.8 gallons in a partial flush and 1.28 gallons in a full flush.

In addition, it has a square toilet bowl, which we found to be more comfortable than most round toilets or elongated toilets. Besides being visually appealing, its seamless one-piece design is also straightforward to maintain. The trapway has a skirted, seamless design as well, which prevents dust from gathering near the corners and edges.

Furthermore, the seat itself is soft closing and is therefore silent and gentle. Moreover, it is easily removable from the toilet body without the need for any additional tools so that you can conveniently clean the toilet. 

What Could’ve Been Better?

We would say that the SM-1T106 Concorde is a very stylish and efficient dual-flush toilet that you can use for your bathroom. But, we noticed that its design makes it seem larger than it actually is. As a result, this makes it difficult and inconvenient to install in smaller bathrooms. 


  • Great for medium and large bathrooms
  • Easy to maintain
  • The fully glazed ceramic body prevents stains
  • Visually appealing and modern style


  • Difficult to install, especially in small bathrooms

True to its brand name, Fine Fixtures has produced some of the finest bathroom fittings and accessories ever since its inception. And the MOTB10W is also no exception. It is a water-efficient, one-piece dual flush toilet that is easy to install.

Why Did We Like It?

The MOTB10W features an efficient dual flush that does not use more than 1.6 gallons per flush, thereby helping to conserve water. The round bowl of the toilet facilitates a rounded siphon action that provides a powerful flush without any clogging or leakage.

Furthermore, the fully glazed ceramic surface is highly dirt and stain-resistant. As a result, it can remain clean for a long duration. On top of that, the 2-inch wide, fully glazed trapway prevents dust from gathering in the edges or corners while eliminating the chances of leakage.

The seat design is slim, and the soft seat cover is silent and gentle, which prevents slamming. In addition, the compact, one-piece design makes it great for small to medium-sized bathrooms. 

What Could’ve Been Better?

Despite being a compact, one-piece toilet, we had quite some difficulty installing it in our bathroom. The installation instructions are a little vague, which we thought was the cause of this problem. So, unless you have the proper experience, you may find this to be somewhat inconvenient.


  • Powerful and efficient flushing
  • Easy to maintain
  • Does not clog or leak
  • Suitable for small and medium-sized bathrooms

And so, it is safe to say that the CST746CSMFG.10 Drake is one of the most reliable and efficient dual flush toilets available today.

Buying Guide For The Best Dual Flush Toilets

By now, you must have gone through our list of the top 10 dual-flush toilets. But have you decided on which one you want to buy yet? If your answer is no, or if you are feeling a bit confused about it, then it is pretty normal. 

Picking the best dual-flush toilet for your bathroom might not be as simple as you may think. Believe us when we say that we faced similar problems when we went looking. We had to take into account different aspects and factors so that we could prepare the above list.

So, if you find yourself in a similar dilemma and confusion, then worry no more! We have prepared this buyer’s guide that highlights some of the critical factors that you should consider before you pick the toilet that suits you.

Therefore, we suggest that you read on to learn what these factors are.

  1. Water Efficiency

For a dual-flush toilet, water efficiency is undeniably the most crucial factor for consideration. In that regard, the EPA has set the maximum flushing capacity for toilets at 1.6 gallons. So, you should definitely look for toilets that use 1.6 gallons or lower volumes of water per flush.

Conversely, you should try to determine if a toilet has a WaterSense certification. A WaterSense-certified toilet implies that it meets the EPA’s standards for water efficiency, which will thereby help you to save on your water bill.

  1. Noise Levels

Nobody wants a noisy toilet for their bathroom since it is not only annoying but also quite inconvenient. So, before buying a dual flush toilet, you should make sure that it has silent flushing or generates as little noise as possible.

The noise is often generated by poor water flow in the bowl. So, if your toilet is noisy, it can indicate that your toilet has a poor design. Also, a hard toilet seat can slam into the toilet, which makes it pretty loud.

  1. Ease Of Maintenance

Another major factor that can make a difference is the ease of maintenance. Cleaning and maintaining a toilet requires a lot of water in addition to labor and chemicals. So, if it is difficult to maintain, it can defeat the entire purpose of a dual-flush toilet.

Additionally, a toilet that requires little maintenance or is easy to clean is very convenient as it requires very minimal physical effort for its upkeep. Furthermore, it implies that you can use it for a long time without extensive maintenance, which makes it cost-effective as well.

  1. Comfort Levels

Comfort levels play a significant role in making the toilet easy and convenient to use. Considering the purpose that it is used for, it is safe to say that an uncomfortable toilet is a massive inconvenience.

Therefore, you should absolutely ensure that a toilet is comfortable before you buy it. And for that, you need to check the toilet’s height, size, and design. You also need to determine whether you want to use the toilet in a large, medium, or small bathroom.

  1. Shape and Size

Even though it might seem insignificant, the shape and size of the toilet play quite an important role. It determines whether a toilet is suited for a particular bathroom or not. In addition, the shape and size can also determine how comfortable the toilet is for you, as we have stated in our previous point as well.

Dual Flush Toilets FAQ

  • What is the difference between dual flush and single flush toilets ?

    A single flush toilet uses a single flushing mode for both solid and liquid wastes. On the other hand, dual flush toilets typically come with two flushing modes for solid and liquid wastes, respectively.

  • How does a dual flush toilet actually work ?

    Unlike a conventional toilet, a dual flush toilet comprises a specialized flush valve. This flush valve dispenses different volumes of water from the tank, based on which flush button has been pressed.

  • Which button do I push on a dual flush toilet ?

    The buttons on most dual flush toilets clearly indicate the type of flush mode for either waste type. Full flush is typically used for solid wastes, while half flush is used for liquid wastes.

  • Dual Flush Toilet


    Besides helping you save on your water bills, a dual-flush toilet is also pretty sustainable for the environment. So, it is high time that you replace your conventional single-flush toilet with a dual-flush one.

    But given so many choices on the market today, how do you decide which one to get? That’s why we have made this comprehensive review-cum-guide. And at the end of this article, we hope that we have been able to help you in your quest to buy the best dual-flush toilet.

    Before we depart, let us reiterate our top recommendations. The Woodbridge T-0019 is overall the best pick, thanks to its features and price. But if you want a more affordable option, you should get the Swiss Madison St. Tropez

    And if the price is not a constraint, then you can get the American Standard H2Option, which comes with several features and is pretty customizable.

    Now, with that out of the way, it is time for us to say goodbye. Until next time!
