Best Dual Flush Toilet Reviews 2024 [Most Popular 10 Toilets]

Best Dual Flush Toilet ReviewsEven though dual flush toilets have not been on the market for so long, they have started gaining popularity because of their water efficiency. Dual flush toilets are unique because they offer flushing options for both liquid and solid wastes. As a result, little water is wasted, and the user also gets to save on their water bill. Depending on your choice, you can select a one-piece or two-piece dual flush toilet. These are smart toilets. But how to find the best dual flush toilet that works great?

For dual flush toilets to serve their purpose, you need to get the right dual flush toilet so that you don’t end up wasting even more water. This is because there are some lower-quality flushing toilet models that might force you to flush more than 2 or 3 times—besides it being annoying, flushing more than once negates the purpose of dual flush toilets, which is mainly to save water.

What is a dual flush toilet?

A dual flush toilet is a variation of the flush toilet that utilizes two buttons or a handle system in order to flush two different amounts of water. This is the best toilet type for you if you want to reduce the amount of water your toilet uses. This toilet is convenient in that it has a partial flush for liquids and a solid flush for solids. So, if you’re a person who frequents the toilet for short calls, you will save half of the water you could have used in a conventional flushing toilet.

What are the advantages of a dual-flush toilet?

The dual flushing system is none other than the biggest water-saving technology in the particular toilet sector. Why should you avoid a single-flush toilet?

-Traditional, outdated design and mechanism
-Less powerful flushing system
-Not water-efficient like dual-flush toilets.
-Might clog frequently
-Not an eco-friendly unit.
-Utilize the same amount of water to flush urine.

But a dual-flushing toilet has several eye-grabbing advantages that are discussed below,

Tremendously water saving

The dual flushing system is mainly discovered to save water. They are mainly called high-efficiency toilets (HET) toilets because they save a lot of water. The traditional toilets use almost 5 gallons of water per flush, whereas the dual flushing toilets consume, on average, 1.6 gallons of water per flush. That means it saves a gigantic amount of water in everyday use. 


Though dual flushing toilets are not that cheap in price but can be cost-effective in some other ways, and you might wonder how that is possible. It is possible, as this toilet model saves more than 4,000 gallons of water every year. Now calculate by yourself how much money that would be. Saving water means indirectly saving some water bills. Nowadays, the government has increased the water bill to impose a hard rule on saving water. That’s why this toilet model can effectively save some on your electricity bill.

Easy and lower maintenance 

It is proven that dual flushing toilets need less maintenance than a single flushing system. Why? The single flushing system uses siphoning pressure to evacuate the waste; on the other hand, the dual flushing system uses a gravity-fed mechanism to flush away the waste; also, there is a supporting system like the broad trapways that helps to evacuate the waste more easily. The bottom line is that fewer skid marks are found in dual flushing toilets, and you don’t need to clean the toilet regularly.

Sleek design 

One of the most significant alluring factors about the dual flushing toilet is that they are super trendy with an astonishing design. This toilet’s sleek and modern architecture amazes anyone, and this kind of toilet increases the glamor of the washroom and adds a tremendous sense of aesthetics to the bathroom interior; that’s why the trend followers use this toilet in their bathroom more sleekly.

Single flush vs. dual flush toilets comparison

It has been a protracted debate about which type of flushing system is more appropriate for a long time. We will discuss this scenario based on some astounding criteria; let’s begin with.

Compare water usage

Undoubtedly, the dual flushing system is far better in terms of water usage considerations. The single flush uses more than 3 gallons of water per flush. On the other hand, the dual flushing system uses not more than 1.28-1.6 gallons of water per flush for dumping solid waste and less than one gallon of water per flush for evacuating liquid waste. On average, the unit use 1.1-1.28 GPF.

Aesthetical design

This depends on the taste and choice of people. Some prefer the old classical one-button flush; for them, the single-flush toilet is more suitable. But some people like the contemporary design, like the dual button function, and the dual flush toilet is best for them.

Cost factor

It is a general fact that the single flush toilet is a lot cheaper than the dual flush toilet. And what is the reason behind it? It is more obvious that the dual flush toilet system uses a more complex toilet system. Here you will find two types of flushing methods. One is a full flush, and the other is a half flush. Maintaining two different toilets requires more complex and extra toilet parts, so it is pertinent that dual flush toilets will be more expensive than single flush toilets.

Maintenance procedure

It is pretty much easier to maintain a single flush toilet than a dual flush toilet because it is difficult to find the parts of the dual flush toilet. In case you have some problem in any of the segments of the dual flush toilet, then you won’t find it easily.


After looking at some of the best dual flushing toilets on the market, you can now go ahead and select a toilet that meets your needs and budget. Dual flush toilets are usually costlier than traditional flush toilets, but they help you save water and are easier to maintain. Choose a good dual flush toilet that fits perfectly in your bathroom, and it is possible. It should blend with your bathroom decor.

Apart from looking at aesthetics when selecting a dual flush toilet, you should also consider size, style, bowl design, flushing system, and any other added features. Note that the more advanced a toilet is, the more expensive it will be. For instance, in this review, you cannot compare the Toto Neorest and American Standard H2Option, as the former is more advanced with amazing features.

Overall, these are amazing toilets that will help you save water and lower your water bill at the same time. Just find the best dual flush toilet for your bathroom.


How is a dual flush toilet beneficial over other types of toilets?

Answer: The dual flush toilet is different from other types of toilets because it lowers the water bill, thus saving some cash, saving water, which is good for the environment, and also requires little maintenance.

How long should my toilet parts last?

Answer: It all depends on some factors and the quality of the parts. The replaceable parts, such as the flappers and seals, usually last for about 4 or 5 years. But if you utilize a chemical bowl cleaner, some flappers won’t last for a year. So, depending on the material that a flapper is made of, some will deteriorate, while others will tend to stiffen up and lose their real shape and flexibility.

Also, factors like the quality of water determine if the parts will last longer or not. In case your water source is heavily chlorinated, then most of the toilet parts that come into contact with water won’t last long. Additionally, if there is grit, sand, or a lower PH, most parts won’t last as long as desired.

Which toilet brands should I consider buying from?

Answer: Since there are so many dual flush toilet brands on the market, it is very important that you buy from a reliable and re-known toilet brand. Ensure that you go through reviews to weigh which toilet is best suited for your needs or if it has issues. Some of the best brands to consider buying from are Toto, Kohler, American Standard, WoodBridge, and Swiss Madison, to name but a few.
