If you are like me and are happier when you have a clean bathroom, you know the importance of having an even more sanitary toilet, especially one that cleans itself with a single flush. To keep my home clean, I started researching online and landed on something called a dual flush toilet.
To refresh your mind, a dual-flush toilet is a flush toilet built with a handle mechanism or features two buttons to flush different amounts of water. That means you press one button to release fewer amounts of water to clean the toilet after peeing.
You use the other button to release more water at high pressure to flush away after going number two. As you can see, this is a beautiful toilet to have in your home.
Furthermore, the dual-flush toilet is popular with many residential and commercial properties that have installed these toilets thanks to their water-saving ability. Armed with this knowledge, I set aside time to learn more about this glorified type of toilet.
By visiting various stores, blogs, and forums, I came up with a list of six different types of dual-toilets with rare reviews. To make things much easier for you, I have made a list depicting the best to the most affordable unit.
Please use the research below to your advantage, especially if you’re in the market for a dual-flush toilet…

What Is A Dual Flush Toilet?
A dual-flush toilet is built as a flush toilet variation incorporated with a hand mechanism or two buttons to flush different amounts of water. The system was developed and released into the market by in 1960 by TOTO, a Japanese sanitary product manufacturer.
The dual-flush toilet has been adopted universally, with countries such as Israel, New Zealand, Australia, and Singapore mandating all modern buildings to install this type of toilet. The thing is, the more intricate the dual-flush mechanism, the higher the price it fetches.
What Are The Benefits of Using A Dual Flush?
The cost savings realized are immense. The toilet brings down the water usage by 4,000 gallons annually in a residential household.
Dual flush toilets are high efficiency that uses a maximum of 1.6 gallons per flush as opposed to the older models that use between 3.5 to 5 gallons per flush. The lower the water usage, the better the environmental impact.
Dual Flush Guide: How To Choose The Best One
When it comes down to selecting the best dual flush mechanism, you should know which is the best unit that meets your needs. Below is a small but significant guide you should use;
Warranty Coverage: when in the market to buy a dual flush toilet, always consider one that has the best warranty cover. One to two years cover is a good start.
You will be guaranteed of its quality build and zero maintenance costs should you need maintenance while the cover is in play.
Water Usage: depending on the frequency of use, you should get a toilet unit that uses the least amount of water per flush. However, if you have enough traffic using the unit, you’re better off going for a 1.6gallon toilet that will leave behind a clean bowl in a single flush.
Flushing Mechanism: the unit employs a large trapway and a wash-down flushing design to push down wastewater into the drain.
Since it eliminates the need for siphoning, the system requires minimal water per flush as the large diameter trapway allows the water to flow out of the bowl with ease.
Size and Space Consideration: Given the size of your bathroom, always go for a toilet unit that will fit without any struggle. Make sure that you take the right measurements of your bathroom before placing an order.
