Buyer’s Guide

What should you consider when you’re deciding between these top-rated toilets? As we’ve earlier mentioned, finding the most suitable dual flush toilet can be tedious due to the numerous products on the market. To ensure that you do not spend your money on the wrong choice, you have to first consider some factors. By doing this, you’ll be armed with the right information on what to look for when choosing the unit to purchase, making the process far much easier.

Here are some of the things to factor in before choosing a dual flush toilet:

Best Dual Flush Toilets -1

Toilet Material and Styles

There are two different dual flush toilet styles: one-piece and two-piece models. It is up to you to choose the method that works best for you and your space. The two-piece style is the most common, and in this style, the seat tank and bowl are separate items and can be independently replaced. Most users prefer this option because it is easier to find the parts, and they tend to be more affordable than one-piece toilets.

The bowl and tank are attached in a one-piece style, and toilets in this style are more comfortable to install as opposed to their counterparts. If you’re interested in one-piece toilets read our guide – 10 Best One-Piece Toilets

If you’re working with a tight budget, you might want to go for two-piece toilets. But you should also know that one-piece toilets come in a sleeker design, and they are less likely to suffer a build-up of bacteria and germs.

The American Standard H2Option unit is an instance of a topnotch two-piece toilet style, while the Toto G400 Washlet unit is a great advanced example of a one-piece toilet style.

Water Usage

Another vital factor to keep track of is the amount of water per flush the toilet uses. The essence of dual flush toilets is their ability to flush effectively while consuming less amount of water. Less water consumption means that you save on water bills with each flush, and you get to conserve water and protect the environment. When purchasing a dual flush toilet, you should check for the amount of water it uses for both its light flush and heavy flush options. To learn more about the smart toilet flushing technologies read our review of the 9 Best Flushing Toilets

This is calculated with the GPF – gallons per flush. Most products on our list use between 1.28 GPF to 1.6 GPF/ 0.8 GPF to 1.0 GPF for their heavy and light flushes, respectively. What’s more, most of these products are also certified by WaterSense (EPA), the U.S. Environmental Protection Agency program designed to encourage efficiency in water use.

Be sure to go for a commode that enhances the overall outlook of your bathroom, and makes your toilet experience enjoyable. Another thing you should note is that toilets are available in multiple shapes, heights, and sizes, so get one that suits your needs. Be it a wall-mounted toilet like the Toto CT418F#01 Aquia unit, a one-piece, two-piece, or compact toilet, only opt for a design that works best for you.
However, regardless of the type or design, you should check for the toilet height.

Typically, toilets are around 15” height, but you can also get toilets with comfort-height. These toilets are around 17” -19” height, and these are ADA-compliant. If someone is elderly or has a disability, then you need an ADA-compliant commode.

One instance of an ADA-compliant comfort-height toilet is the Convenient Height Model S Extra Tall Toilet, which measures as high as 21 inches.

Bowl shapes are also important. So, you have to choose between elongated and round bowl shapes. Elongated toilet bowls are more comfortable, but round bowls occupy lesser space, and they work in a lot of bathrooms.


Other Features

Some dual-flush toilets come with other advanced features to enhance the user’s convenience. Some of the units on our list, such as the Toto MS992CUMFG#01 G400 come with features like automatic lid opening and closing, a self-sanitizing bidet wand, that rinses you after your toilet business, and a dryer.

Additional costs

Some toilets do not come with seats, so you need to check this out and purchase a seat if necessary. Moreover, there are models that need to be professionally installed, so be prepared to pay extra money for the installation.

Warranty Coverage

One way to ascertain the durability of a dual flush toilet is by checking the manufacturer’s warranty. Most commodes on our list come with generous warranty coverage from the manufacturer. For instance, the American Standard H2Option comes with a limited lifetime warranty on its china and a limited 5-year warranty on mechanical parts.
