Have you ever watched your toilet swirl around endlessly and seem to take forever before the water is totally flushed? You have probably thought to yourself that takes a lot of water to get rid of just a little bit of urine in the bowl. Well if you did you would have thought right. That is one of the main reasons that companies now make dual flush toilets that are designed to save a lot of water. That is why we have taken the time to help you find the best dual flush toilet by doing a series of in-depth dual flush toilet reviews.
What exactly is a dual flush toilet? It is a toilet that is designed to save hundreds of gallons of water use in a single month. These toilets can do this because they have two flushing positions on their handles or activation buttons. Slight pressure on them will trigger a smaller flush that is great for getting rid of urine. When full pressure is applied on the handle or button they will clean solid matter from the bowl with a more powerful flush.
There are many dual flush toilets available in the plumbing marketplace. After taking a closer look at many of them these are the ones that we feel worked the best dual flush toilet reviews and should be brought to your attention.
What is a Dual Flush Toilet?
Most dual flush toilets have their flush activated by a push-button on top of their water storage tank. This button is actually divided into two parts. There is a large and small button as a result of this division.
How Does a Dual Flush Toilet Work?
Now, let’s look into how dual flush toilets work. The large button uses the full flush capacity of the toilet and lets all the water out of the toilet’s tank at once. This is a more powerful flush that should only be used when there is a solid waste in the toilet. It generally cleans the toilet bowl completely out without leaving any residue.
The small button is the extreme water-saving button. It is used predominately when there is online urine present in the toilet bowl. When the small button is pressed it does not let all of the water out of the toilet storage tank at once because it is not necessary when only getting rid of urine in the bowl. This saves a lot of water over a long period of time.
Single Flush vs. Dual Flush – Which One Should I Buy?
As the name suggests, single flush toilets come with one flush mechanism. One will use approximately 5 gallons of water for every flush with this kind of toilets. on the other hand, dual flush toilets come with two buttons on their tanks. One button is for a less powerful flush which you can use for liquid waste while the second button is for more powerful flushes.
The main difference between single flush and dual flush toilets is the amount of water consumption. Dual flush toilets are more environmentally friendly and they can drastically lower your water bill. Therefore, they are a great option for those who want to protect the environment while saving some money.

Best Dual Flush Toilet Reviews (Updated List)
1. Toto MS992CUMFG#01 Neorest Dual Flush Toilet
This is a simply amazing toilet, to say the least. It has many features that most people would really be surprised that you would find on a toilet. If you are the type of person that likes to make even going to the bathroom easy, then you will absolutely want to have this model toilet. It even flushes great and that’s why it is number one on our list.
Special features: Body dryer, bidet, seat warmer, auto flush, an auto seat close, remote control compatible
There really are many things that we like about this toilet. Since we are talking about dual flush toilets we have to mention how well this one does it. This toilet has a low 0.8gpf flush for urine and a jet-assisted 1.0gpf for solid waste. The bowl cleans very completely for such a low rate of water use.
This model toilet needs a dedicated GPS protected electrical hook up which makes it much more difficult to install than toilets that don’t require electrical power.
2. Woodbridge Dual Flush Elongated One Piece Toilet
You have seen the top of the line fanciest toilet in review number one and now we go completely to the other end of the spectrum. This is a very simple and affordable model dual flush toilet that works great. It is a toilet model that will allow those of us that are on a budget to have the water savings benefits of dual flush toilets just like everyone else.
Special features: Includes rings and bolts, soft closing, easy to clean, quiet operation, stylish
We really like the looks of this dual flush toilet. It is very simplistic in design yet is modern and sleek looking at the same time. This toilet will really compliment the looks of just about any bathroom setting you install it in.
There were two concerns we had with this model toilet. When the seat is up it partially blocks the flushing mechanism. It is also a little high for children and smaller users.
3. EAGO TB353 Dual Flush Eco-Friendly Ceramic Toilet
Here is another simple yet good looking and well-designed dual flush toilet. It is also a very affordable price for all that you get with it. The dual flushing capability on it will really save you a lot of water over time. It will nicely complement the décor of many different styles of bathrooms.
Special features: the soft closing seat, powerful flush, sleek modern design, easy to clean, balanced water distribution.
The power of the flush on this model with the higher setting is pretty incredible. This is most likely due to the fact that this toilet features a 3” tank valve opening. That means that more water gets into and out of the bowl faster so it completely cleans the solid waste out of the toilet bowl.
One thing that we really did not like about this toilet is the lid and seat combination that came with it. It is thin plastic and built a little flimsily. Improving the quality of the seat would make this toilet much better.
4. Ariel Bath Hermes Contemporary Dual Flush Toilet
Here is a water-saving dual flush toilet that has a more contemporary style to it. It is very simple to operate yet flushes powerfully and leaves the bowl sparkling clean almost every time. This toilet is quite different in looks than many of the other toilets we will review and will go great with any contemporary themed bathroom.
Special features: Unique elongated shape, dual flushing, soft closing toilet seat, one-piece construction
The design of this toilet is very different than most people are used to seeing in bathrooms. It has a very thin and high tank that not only gives this toilet a unique look but also helps it take up less space. This toilet does not stick out from the wall as much as regular style toilets do because of its thinner tank design.
The installation with this toilet makes it more difficult to install. This model uses its own 6 bolt toilet plate to mount it to the floor. Allow yourself at least an hour just to attach the holding plate to the floor.
5. Saniflo 023 SANICOMPACT 48 Dual Flush Toilet
Here is a very interesting and efficient toilet model. It is considered a dual flush toilet because you can flush it like a regular toilet or use its maceration feature in combination with the flushing mechanism. It uses only a very small amount of water per flush and cleans the bowl very thoroughly each time.
Special features: Vertical flushing capability, up to 100’ horizontal flush, can attach a sink drain to its plumbing, super-compact design
The maceration feature on this toilet is very interesting, to say the least. It grinds the solid waste down into liquid slurry so it can be flushed out easily. This toilet can also be plumbed below the level of your household plumbing and still work.
Here is another toilet that requires you to put an electrical connection to it. We are not big fans of electrical connections in harsh bathroom environments. This toilet also clogs easily if you put anything besides toilet paper in the bowl.

6. American Standard H2Option Siphonic Dual Flush Toilet

It has a modern design with an exposed style trap that gives it a distinct contemporary look. It has an excellent dual flush capability and a sleek glossy look that is easy to keep clean. This toilet is also available in one of three different colors.
Special features: extreme water-saving, siphon flush action, three color choices, tall seat height
The light urine flush on this model toilet will save you much water over time and save you on your water bill too. It uses only 0.92 gallons of water on each slightly activated flush. This is a toilet that will definitely make your home a little greener.
There is very little water that sits in the bowl in this toilet. That means that it will sometimes leave some excrement residue on the sides of the toilet after it flushes. A second flush usually takes care of it but that is defeating the purpose of having a water-saving toilet.
7. Renovator’s Supply Dual Flush Corner Toilet
This is another very unique design that is supposed to open up more space for you in your bathroom. That makes this toilet ideal for installation in smaller size bathrooms. It has a nice push button dual flush feature and a good looking stain and scratch-resistant finish. It looks as good as it works. This toilet is also one of the easier models on our review list to install.
Special features: Stain-proof/Scratch-proof China Finish, water-saving dual-flush, space-saving corner design, push-button convenience
The design of this toilet is very unique, to say the least. It not only saves some space in your bathroom but it also looks great while doing it. You will be amazed when you see how little room this toilet takes up compared to more conventional toilet installations.
There is a lot to like about this toilet but the lid and seat combination is not one of them. The design of these items is very flimsy and there is a lot of wiggle to them when they are being opened and closed.

8. TOTO CST424EFG#01 Promenade E-Max Dual Flush Toilet
This is a really solidly made dual flush toilet from the reputable manufacturer Toto. It is more of a crossover design that can be used in both older and more modern bathroom themes. It is powerful yet flushes quietly when working. This Toto toilet has many computer designed features that contribute to how well it works.
Special features: advanced computer designed bowl and trapway, quiet operation, larger water surface, powerful flush
The high flush setting on this model toilet is very powerful. If you are the type of person that detests cleaning solid waste residue out of your toilet bowl, then you will really like this model toilet.
This is a model toilet that has a high seat design. While that makes it great for taller people to use you definitely do not want to install this model toilet in a bathroom that your children will use.
9. Aquia II Dual Flush Elongated 2 Piece Toilet
This is a very good water-saving dual flush toilet. Aquia has done a very nice job with the design of it. This two-piece toilet has a unique shaped bowl design that broadens out the water level so it flushes clean in most instances. Everything you need for its unique installation is included in the package too.
Special features: two-piece construction, extreme water-saving, stylish design, multiple color choices, easy to install
This is a very stylish model toilet that will fit well in both contemporary and modern bathrooms. It has a narrow two-piece design which makes the overall appearance of your bathroom look bigger. This is a very versatile toilet as far as the looks of it go.
One very annoying aspect of this toilet is the flushing button. When you are trying to do a full flush you have to hold the button down for a very long period of time. This seems like it would be a tough toilet to install also because of the way it is designed.
10. Toto CT418FGNo.01 Aquia Wall-Hung Dual-Flush Toilet
If you are looking to save room without having to sacrifice dual flush capability then you should take a close look at this top-notch wall-mounted toilet. Not only will it save you on your water usage but it easy to maintain and use. It also features Toto’s exclusive SanaGloss finish which helps it stay shiny even after years of use.
Special features: Space-saving wall mount toilet, easy to clean around, water-saving, simple design
Wall-mount toilets have some distinct advantages over floor mount toilets. For one, their plumbing is not exposed so your bathroom does not look cluttered. They are also very easy to clean around since they have no base that is mounted to the floor.
There are a few concerns we had with this product. One is that it comes with no seat and absolutely no hardware either. The other concern we have is that is has a simplistic design that does not really enhance the looks of your bathroom.
How Do You Adjust a Dual Flush Toilet Mechanism?
There are some small water level adjustments that you can make on a dual flush toilet. If you remove the toilet tank cover you will see the fill assembly in the center of the tank. At the top or the side of the part that floats up and down on the fill valve, you will also see a stainless steel screw.
This screw will allow you to adjust the water level on the tank. You will need to turn the screw with a Philipp’s screwdriver in order to raise or lower the water level. If you turn the adjustment screw clockwise it will raise the water level in your tank. Turning the screw counter-clockwise will lower the water level in the tank.
This can be useful to do such things as make your toilet save even more water or it can flush a little more powerful.
How Much Water is Used Up When a Dual Flush Toilet Is Flushed?
This is a question that can only be answered if you know which model dual flush toilet you are talking about. No two manufacturers make the flush rates on their toilets exactly the same. But there is one thing you know when you are talking about a water-saving toilet.
There is a set standard that makes a toilet a water-saving model. According to the EPA’s WaterSense program in order for a toilet to be certified as a water-saving toilet model, it must use 1.6 gallons of water per flush or less. A high-efficiency toilet (HET) is one that uses 1.3 gallons or less.
So although you don’t always know the exact gallonage a toilet uses when it flushes, you will know approximately how much water dual toilet water uses per flush by whether it is certified water-saving or not. Every toilet on our review list is considered to be a water-saving model because none of them use more than 1.6 gallons even on the most powerful flush setting.
Dual Flush Toilet Frequently Asked Questions
There are certain questions that we get over and over again about dual flush toilets. We thought we would share them with you in case they are questions that you have been thinking about too as far as dual flush toilets are concerned.
Would I be better off not getting a dual flush toilet and get one that flushes more powerfully?
Water flow is not the only key as to how well a toilet flushes. Even though dual flushing toilets are considered to be water-saving toilets they still flush very well. They accomplish this by doing such things as making the surface of the toilet very smooth so nothing can cling to it.
These toilets are also usually specially designed to be a shape that is conducive to complete cleaning and they let water get from the tank to the toilet bowl faster which creates more pressure.
Which works better a one-piece dual flush toilet or a two-piece dual flush toilet?
The answer here is whether a toilet is built using one-piece construction or two-piece construction makes no difference in how well it flushes. There is absolutely no reason why a two-piece constructed toilet cannot flush just as effectively as one that uses one-piece construction.
It is up to the innovativeness of the manufacturer’s toilet design that determines how well a toilet flushes. The number of pieces in its construction has nothing to do with it.
Are there any drawbacks when it comes to dual flush toilets?
The answer here is yes.
- Dual flush toilets generally cost a little more than single flush toilets do. This is because of the more difficult plumbing that they are constructed with.
- There are usually not as many styles to choose from when it comes to dual flush toilets as there is with single flush models. This is changing as dual flush toilets keep getting more popular.
- Dual flush toilets are usually slightly harder to operate too. This is because of the way their flushing mechanisms are set up.
Most of the time the water and money-saving benefits of dual flush toilets far outweigh any of the drawbacks associated with them.
What are the advantages of having a one-piece dual flush toilet as opposed to a two-piece dual flush toilet?
There are some distinct advantages to having a dual flush toilet that is made out of single-piece construction.
- They are much easier to clean than two-piece toilets. This is because they do not have all of the tough to clean nook and crannies that two-piece toilets always are seen to have all over them.
- One-piece toilets are much easier to install in most cases. Obviously, they come mostly assembled, whereas two-piece toilets have to have the top storage tank assembled onto the bowl and drain section of the toilet before installation of the toilet can begin.
