Last Updated on April 13, 2021 When starting a home renovation project or even building a new house, the choice of a toilet might not seem like a complicated decision, but you should take care in your selection. A toilet is by far one of the most frequently used items in a house and a dual flush toilet can mean the difference in the amount of water you use each day.

Choosing the Best Dual Flush Toilet
In order to accomplish the goal of purchasing a toilet that will sustain your household for years to come, you should consider a few things beyond color and style before heading to the local home improvement store to make your purchase.
You should be prepared that a dual flush toilet will most likely cost more than the traditional style you are used to. However, keep in mind the savings on your water bill will add up. You may end up saving as much as 25,000 gallons each year by upgrading to a dual flush system.
An older toilet model can use around 3.5 gallons per use, some as much as 6.5, but the standard on a dual flush toilet is just 1.6 gallons per flush. The water savings add up but be prepared to spend anywhere from $230 upwards to $7,000 on upfront costs.
Again, a dual flush toilet system comes down to water use as the single best reason to purchase this type of toilet. As mentioned, the standard on dual flush toilets is 1.6 gallons per flush, but there are toilets available to buyers with an even lower threshold. If purchasing a toilet with the least number of gallons used per flush is critical for you as a homeowner, search for those toiles with a Water Sense label. Toilets must use 1.28 gallons per flush or less to qualify for this standard.
The good news is when it comes to a dual flush toilet, there are several options for handles available on the market. The most common is a round, two-sided button the top of the toilet, but dual-flush toilets also come with knobs or levers. It is really up to preference which is best for you and your home.
Size and Shape
The size and shape of your new toilet also will come down to personal preference and the style and size of the bathroom you will be installing your brand-new toilet in. The first thing many notice when using a toilet is the height.
Your own height and size will make a difference in whether you prefer the average toilet height of 15 to 16 inches, or a higher one that typically can be found ranging from 17 to 19 inches. If you have a physical disability, purchasing a toilet that is easy to get up and down from will not only come down to comfort but a necessity as well.
As far as shape, older styles come in round bowls and newer versions come with bowls typically two inches longer. If you have a smaller bathroom, you might consider a round bowl, but if space is not an issue, the longer one is typically the choice of consumers.

While reading through the options are great, chances are some questions have popped up in your mind that you would like the answer to before shoveling out hundreds of dollars for a new toilet. Below is the answer to a few questions concerning dual flush toilets before you decide which one is best for your home.
What are the advantages of a dual-flush toilet?
Dual flush toilets allow you to select how strong of a flush you need after every single use, which saves water in the long run. It can help you save dollars and cents on your water bill while also helping the environment.
How does a dual flush toilet work?
The trapway in a dual flush toilet, or the hole at the bottom of the bowl, is used along with a wash-down flushing design that pushes waste down the drain. Unlike a traditional toilet, which uses a siphoning action, this system needs less water and the larger trapway allows for more waste to exit at a time.
What is a comfort height toilet?
Today’s comfort height or right height includes toilet bowls that are 17 to 19 inches high. In comparison, a regular toilet comes around 15 inches. These are great for taller people and the elderly, but if you have kids or shorter adults in your house, a regular height is the way to go. If looking for a toilet that will be installed in a compact space, consider a small toilet design.
What does Water Sense certified mean exactly?
The EPA gives a Water Sense certification to a toilet that has undergone rigorous testing to prove they could meet the criteria for both performance and efficiency. Water-saving toilets that have completed this process include a Water Sense certification label.
Making the decision to purchase a dual-flush toilet is the right choice for not only the environment but your household as well. It will save on water bills and allow you to feel guilt-free knowing you are doing your part to save our planet, but that doesn’t mean you need to sacrifice style or comfort, so take your time in selecting the right toilet for your home. If you do, you will be happy with your selection for years to come.
Now that you have an idea of what exactly you want in your new dual flush toilet, it is time to begin shopping.
