A few years ago, toilets flushed waste at a whooping rate of 3.0+ gallons per flush. That’s a lot of clean water going down the drain. And that brings along a huge water bill which, when added to heating bills and other end month expenses, the total figure can leave a disturbing dent in your bank account.
Dual flush toilets are a recent technology that allows you to use less water in the bathroom. As the name suggests, there are two flushing options-light and heavy. Light flushing is used to drain liquid waste while the full flush is for solid waste. This operation happens through two buttons and sometimes a lever with the direction indicated for the two flushing choices.
The best dual flush toilets result in 30% less water use, which consequently results in easily payable bills that don’t affect your financial plans. Additionally, it is great to conserve water and help other areas with shortage get something too.
And now to the most important question, how do you tell which dual flush toilet is the best? You cannot unless you conduct thorough research. But you no longer need to do that as this review takes a look at the finest options and includes a brief buying guide that will help you to make the right choice.

Things to Consider While Shopping for Dual Flush Toilets
You are not here to gamble with your money. We will not question you about that. This section will touch on some important things you must consider while looking at dual flush toilet options to help you make sober decisions. Read them below:
One-piece vs. Two-piece
A debate between one-piece vs. two-piece toilets is a never-ending one. And today, it’s your time to decide which one could work well with your restroom.
A one-piece toilet is exactly as the name suggests; it comes in a single piece. In this design, the water tank and the bowl are molded together. Such a toilet doesn’t come with many grooves, which makes cleaning easier. Given that one-piece units are the latest space-saving models, they are a little costlier than a two-piece.
A two-piece toilet comes with the bowl and tank separated. This can allow you to put the tank in any position you want. This design is traditional and springs from way back to the first toilet days. As such, they are relatively cheap, easy to maintain, albeit taking up too much space.
Let’s come straight on this; performance and functionality are more or less the same. It’s just the design that differs. If you are hell-bent on performance, we suggest looking at the flushing technology in the models you are considering. Check out the image below for a complete comparison.
Are you a parent? Do you always find yourself pulling at your hair after finding toys, wipes, bandages, veggies, and loads of toilet paper?
Yeah. We’ve all been that annoyed—Trust us…Kids (phew).
Besides kids, if you have a commercial property, then it really does work a lot harder than all of you. Basically, it is expected to effectively deal with all your shit-literally. These are some of the incidences where a dual flush toilet with powerful performance cannot be underestimated.
The best flushing systems you should consider include Gravity flush, double cyclone, pressure-assisted, and Tornado. These systems sink waste within a single pull of a lever (or button press). Sometimes extremely powerful flushing technologies can result in a bit more noise. We thought you should know that.
You can also take a look at our article on the best flushing toilets for some choices that will keep your home and commercial places stench-free.
Standardization organizations are quality watchdogs that ensure products work as they should. By purchasing a certified toilet, the chances are very high it will flush effectively, conserve water, and accommodate the disabled members of the family. The most common certifications include ADA (disability compliant), EPA WaterSense for water conservation, and CalGreen for environmental protection.
The Toilet tank refill rate is just as important as flushing performance for bigger homes and commercial spaces. When you have a party, there will always be a queue, and nothing is discomforting like sticking around in the toilet for a little longer just so the tank can refill.
Size and Shape
Dual flush toilets come in many sizes and shapes. However, the two common shapes are a round bowl and elongated. The bow is…err…round and usually a bit smaller. This makes them an excellent choice for those with small restroom spaces.
An elongated design is large and oval in shape. They are recognized as the most comfortable and come highly recommended. This is why they cost a little more than round bowl ones. There are also hybrid toilets whose shape is a combination of these two bowl designs.
Warranty does actually matter when it comes to costly items like toilets. If you are like some of us who are extremely skeptical about quality standards, then pick toilets that offer more than two years. The longest period you are going to get is five years, although most units come with a 1-year limited warranty against company defects.
Frequently Asked Questions (FAQ)
Q. What are the benefits of using a dual flush toilet?
A. There are a lot of benefits to be gained from using a dual flush toilet over the standard flush toilet. Some of these benefits include:
Budget-friendly – Dual flush toilets conserve a lot of water, thereby helping you save up on cash that would have been used to pay for high water bills.
Environmentally-friendly – These toilets consume less water than most toilets, thus conserving a very important water resource. This is a good practice in places with a shortage of clean water.
Q. What happens if I push both buttons on a dual flush toilet?
A. You are supposed to push the smaller button for liquid waste and the bigger button for solid waste. If you happen to push both, probably because your fingers are big, you get more water equivalent to a single press of the large button.
Q.Which is better, a single or dual flush toilet?
A. Most countries and manufacturers are now pushing for dual flush toilets as eco-friendly practices gear up. Dual flush toilets are said to save up to 30% of clean water that would otherwise go down the drain. This water can be channeled to other areas for the betterment of humanity.
Unfortunately, if your dual toilet must be pressed twice to drain waste, it is no better than single flush models.
Q. Which is better, a single or dual flush toilet?
A. It is common for some toilets to constantly run even after flushing. In this case, the first step is to turn off the water from the inlet hose pipe. Carefully remove the lid to avoid damaging the toilet’s internal mechanism.
Now, the cistern is stuck to the bottom. To remove, simply grab it with your two arms, then twist it to one side as you gently pull upwards. For some toilets, instead of twisting, you, instead, press down then pull up.
The culprit is the flush valve washer (looks like a rubber seal), which is located at the lower end of the cistern. Usually, it is scaled, and this is the reason it lets out water. You will need to peel it off gently. The image below shows you what we are talking about.
Once out, give the washer a good clean up and slide back to the cistern the same way it was. Most come with some writing on the side that is supposed to remain on top. If you swap the sides, the seal won’t work properly. Now, once in place, place the cistern back, and if everything went well, then the water should stop running. If it continues, then you need to look for a replacement valve.
This is definitely not the ultimate list of the best dual flush toilets. Rather, we just singled out a few of the top options that come highly recommended by home builders, plumbers, and previous buyers.
Dual flush toilets can also come as wall hung toilets or smart toilets with bidet seats than massage your bottom (amazing, right?). A few underdog brands are actually producing decent kits that don’t cost an arm and a leg (as is common with household brand names).
