Throughout the years, dual flush toilets have gained significant popularity because they are considered as the first choice for thousands of customers on the market. One of the main reasons is the fact that they offer the user two different water levels to choose from with the intention to minimize the water expenditure as much as possible, and in some case studies, this means that the water usage is reduced for more than half.

This relatively new technology is exclusive in comparison with the older models which often use the typical pull/push functioning pattern are known for clogging unquestionably more than the dual flush toilets and the result of “misflush” isn’t new with the older models.

Dual flush toilets do not only minimize the water expenditure but, they have also proven themselves as a truly reliable option in terms of avoiding misflush and preventing clogging.

However, choosing the right dual flush toilet can be problematic at times, because there are hundreds of them available on the market, and each of them differs mainly in price and durability even though the mechanism is the same. Check out our buying guide about the best toilets to see all different types.

In this article, I will review the best dual flush toilets to save you from the need of exploring everything by yourself and doing your own research. Each product mentioned in this article has been analyzed to the very last detail, so let’s get started and see what I have prepared for you!

We are going to start our best dual flush toilets list with a very reliable option. The American Standard H2Option Siphonic is currently among the most highly-rated dual flush toilets on Amazon as well as on the market as a whole, and you’ve likely seen this name multiple times while you were searching for on the Internet which definitely has to mean something. My job is to reveal it for you right now, so let’s see what can you expect from it!

From a design perspective, this model sports a sleek, all-white construction that measures 29.8 x 15 x 29.5-inches, weighs approximately 91 pounds, and if we take a closer look at these specs, I can easily say that this toilet is appropriate for small, medium and large bathrooms because it doesn’t occupy a chunk of space!

In addition, its form has a quite convenient shape and what’s also cool is that the surface is specifically designed to maintain being clean, so, both in terms of maintenance and hygiene, these two attributes make everything be smooth.

To be more precise, the surface does an unbelievably good job in protecting the toilet itself from various things, including fungus, algae, mold and mildew which by default means that you will have to put a considerably less effort for maintenance on one side, while on the other, this also comes handy especially in preventing the chances of staining.

When it comes to the installation, the American Standard H2Option Siphonic pre-installed bolts and grommets which will save you up to 30% of the time you would require to install this unit properly. However, I’d advise you take a close look at the installation instructions if you prefer to install this toilet by yourself, because if you follow them correctly, you will never face any undesirable situations. On the other side, if you face any difficulties, do not hesitate to hire a professional that can do everything for you.

Before we move to the next section, I would also like to inform you that unfortunately, this unit does not come with a seat which may be seen as a fairly normal thing due to the fact that by doing this the company has managed to keep the toilet price low.

Moreover, the American Standard H2Option Siphonic performs pretty well and if you have ever had a chance to take a look at the reviews, you have likely seen that customers expressed compliments regarding its performance. Namely, the toilet’s dual flush system delivers a water flow output of up to 1.6-gallons per flush( full flush) and has a partial flush of 1-gallon per minute. The manufacturer has also set marks on the buttons, so even if you are new with dual flush systems, you will know the way they operate.

But that’s not all! This toilet includes a very useful feature which is known as the power washing. This feature works closely with the Jet-Powered Siphon. To simplify this, the siphon is instantly activated with the push of the jet and once this process is done, the siphon releases the bowl of the used water. By doing this, the flush becomes powerful and smooth at the same time which by default means that your toilet will be extremely clean.

Last but not least, the American Standard H2Option Siphonic meets the EPA WaterSense Criteria, and this is surely a reliable proof that says a lot about this toilet. Being a WaterSense-certified product means that a specific unit is designed to preserve water expenditure on one side, while on the other, that product can be tested by third-party. Well, this toilet meets the criteria so without a doubt I can say that the manufacturer has done a really good job here!

To summarize everything, the American Standard H2Option Siphonic is an affordable dual flush toilet that does not look or perform in such a way, and if you ever decide to purchase it, you will unlikely regret that decision!

The manufacturer has also included a well-written user manual, so feel free to check it out in order to avoid hiring plumbers. However, some users have reported that they had some difficulties reaching the bolts because most of them are situated at the inside, but, this doesn’t mean you will have such “problems” as well.

First of all, I would like you to know that the WoodBridge T-00010 is WaterSense-labeled, and has two flush buttons of which one uses 1.0-gallons per flush liquid waste, while the other uses 1.6-gallons per flush, so, without a doubt I can say that this model has all the attributes of a water-efficient product.

In addition, this toilet uses a so-called Siphon Flushing Action which I particularly like, mainly because of the fact that the toilet remains silent even though it produces a fully glazed flush!

The siphon flushing prevents clogs and leaks as well, and so far, I don’t have any remarks regarding its design and performance.

Last but not least, users claim that they were satisfied with the comfort that is offered by this toilet, and to be honest, I’m not even surprised considering its overall design that makes it suitable for both, children and adult users.

To conclude, the WoodBridge T-0001 is worthy of considering because of two reasons, the first is because it has received thousands of positive critiques from the users on the market, and the second is due to the fact that this unit justifies its price tag with its performance and offers even a greater value for its cost!

I didn’t think twice before I managed to list the Toto Neorest 700H as the best dual flush toilet on the market, due to the fact that this unit covers basically everything and has all the attributes which in my opinion a dual flush toilet should have. Design, comfort, performance. All of these three attributes comprise the Neorest 700H! Intrigued? Let’s see the advantages of having it in your bathroom!

When it comes to the design, the Toto Neorest 700H looks modern and since its fully covered in white, it means that regardless of your bathroom decor, this toilet will suit each bathroom perfectly fine!

In addition, its dimension makes this unit be a real space saver, since if we take into consideration that its dimensions measure only 32.5 x 15.5 x 21.5-inches, by default, it means that the Neorest 700H is compact enough to fit in a small, medium and large bathroom without any problem!

Thanks to its well-made design, this unit is appropriate for young children, adults and even people with disabilities which require special self-care treatment, and I have to express my gratitude towards the manufacturer! They have really cared literally about everyone!

For your information, the package is unlike the conventional toilets, so it requires being a professional in order to install it properly. For instance, If you have never installed a toilet before, then I’d strongly recommend you hire a plumber that has experience with such high-end toilets. Some of the users that we were in contact with the claim that they couldn’t do it on their own, but this is fairly normal due to the fact that not every one of us is an expert in every field, including the process of installing a toilet.

Moving on, the Neorest 700H incorporates many interesting features, so, let’s briefly explain each of them.

Firstly, since we are talking about a dual flush toilet, it means that you will have an option to choose between the two flushing modes such as the 1.0-gallons per flush and the 9.8-gallons per flush. What’s interesting is that this model is WaterSense-certified, and this says a lot especially when it comes to water-efficiency.

Furthermore, this unit utilizes a built-in automatic feature that opens and closes the lid, so from now on, you won’t deal with slamming on one as well as you won’t have to worry whether you or your loved have left the lid up.

Since I’ve mentioned the lid, there is yet another interesting thing. Once you open the lid, you can immediately notice the nightlight, and if you ask me, this is a really convenient feature, especially when you require going to the bathroom during the night.

But, the manufacturer did not stop here! This toilet integrated a temperature control on the seat, a self-cleaning wand, an air dryer and even an air deodorizer which will drastically improve the hygiene of your bathroom, and I have to admit that Toto does really deserve our compliments here!

Moreover, keep in mind that this toilet is tank-less, which means that it uses electricity to power everything and the flush part isn’t different at all. So, if your bathroom faces a power failure this could make this unit unable to flush. This shouldn’t sound like a disadvantage, because the Toto has already backed you up with the needed information in case of an emergency flush. All you would have to do would be to follow the instructions that are written in the manual!

To conclude, the Toto Neorest 700H is indeed a masterpiece that should be considered as a must-have dual flush toilet for every household who is not tight on budget but would like to invest in a premium looking and performing toilet!

How Dual Flush Toilets Work

One of the best dual flush toilets that we recommendFirst of all, let’s make a comparison between the standard and the dual flush toilets in order to have a better understanding of their performance. Standard toilets use a so-called “Siphoning” method which consists of a siphoning tube whose purpose is to evacuate waste. This method performs in such a way that when air enters the tube, the siphoning action stops.

On the other side, dual flush toilets employ a larger diameter trap way which has proven itself as a far more reliable and better option when compared with standard flush toilets mainly because of their ability to prevent clogging, a common thing that often happens with standard flush toilets.

Contrary to upflush and portable toilets, dual flush toilets are a bit more expensive. Not only because of the fact that they clog as often as the conventional toilets, but also because they save more water and are far more efficient.

Types of Toilet Flushing Systems

The most common types of toilet flushing systems are:

  • Dual Flush: These systems have gained popularity throughout the years and can be named as one of the most effective if not the most effective flushing units. Dual flushing systems use less water without sacrificing performance.
  • Double Cyclone: Currently, they are a new technology from Toto toilets but what’s interesting is that they have also become popular throughout the years mainly because of the ability to use approximately 1.28 gallons of water per flush.
  • Gravity Flush: Gravity flush systems as the name suggest, are using the water to make a flushing pressure which basically forces everything from the tank and bowl to be released through the trap way.
  • Pressure Assisted: These toilets are a bit nosier than the other 3 systems, but what’s good is that they will less likely clog due to the fact that they are powerful. In practice, they are using pressurized air with the intention to let the water into the bowl and eliminate the waste.

Advantages Of Having A Dual Flush Toilet

  • Cost-Efficient: Dual flush toilets require less water usage and therefore, its performance will not affect the cost of your monthly water bills.
  • Water Savings: According to United States Environmental Protection Agency (EPA), if each conventional toilet in the U.S is replaced with a new, high-efficient model, this could save up to 2 billion of water every day. So, having a dual-flush toilet does really save water and it is a good practice since every one of us should care about the environment.
  • Less Maintenance: Dual flush toilets offer a better, clog-free operation if you compare them with the standard toilets, and what’s even better is that you will unlikely have to hire plumbers to fix some defects for you.
