Best Dual Flush Toilet Reviews

White Toilet In Front Of Green Wall

Thank you for stopping by and checking out my post on the Best Dual Flush Toilet Reviews.

Money does not come by easily these days. Cutting costs on utility bills is one of the first things that come to mind when it comes to saving money. Sales of energy efficient appliances are on the rise. They not only give lower bills but they also help protect the environment.

There is one great way to save up to hundreds of hard-earned dollars annually. That is by replacing a standard toilet with an ecologically friendly dual flush toilet. If you are not convinced, below are some of the advantages of dual flush toilets compared to traditional toilets.

More environmentally friendly

Before the implementation of the Federal Energy Policy Act in 1992, every toilet flush used around 7 gallons of water. Nowadays, the usual amount of water used per flush in a traditional toilet is 3.5 gallons.

However, with the introduction of dual flush toilets, there are now different mechanisms for solid and liquid waste. The dual setting mechanism lets you choose between a low volume flush or a high volume flush by pressing a button or lever. The low volume flush is for liquid waste and the high volume flush is for solid waste. This new low flush setting conserves more water.

Dual flush toilets are now categorized as high efficiency toilets (HET). They comply with the National Energy Policy Act of 1994 – using no more than 1.6 gallons per flush (gpf) compared to traditional toilets. A low volume flush only uses as low as 0.8 gallons of water and a high volume flush only uses 1.6 gallons of water. Research has shown that low-flow toilets consume 8 gallons per day while dual flush toilets only consume 4.8 gallons per day.  Multiply those savings by 365 days and that equates to a lot of saved water per year!

More money saved

Secondly, dual flush toilets consume less water, resulting in cheaper monthly water bills. The Environmental Protection Agency’s report gives an estimate saving of 4,000 gallons annually for households that use dual flush toilets.  That will lead to big water bill savings per month.

Less maintenance required

Thirdly, older toilet models simply employ a  pressure siphoning mechanism to get rid of waste. Dual flush toilets utilize gravity more efficiently to dispose of waste. As a result, this system greatly reduces the risk of clogging which results in fewer plumbing expenses and less time spent on repairs.

Ecologically friendly

Finally, dual flush toilets significantly reduce the number of waste that gets sent to treatment plants.

Having your own dual flush toilet is not only convenient, but is also durable, water efficient and will be more advantageous in the long term. That is why we have compiled a list of the best dual flush toilets. We want to help you search for the most efficient toilets that suit your needs best. Without further delay, here are the Best Dual Flush Toilets Reviews.

Best Budget Dual Flush System

Toto CT418FGNo.01 Aquia Wall-Hung Dual-Flush Toilet

This Toto model is perfect for those who are on a tight budget but still want to replace their current toilet. It has satisfactory features and will help you save money upfront and in the long run.

How To Choose The Best Dual Flush Toilet

Dual Flush Toilets have many advantages over older models. The Environmental impact comes first. Water conservation is very important and dual flush toilets do this efficiently. Saving water helps to preserve our environment. With reduced demand, less water is required to deliver and process water. This reduces pollution and conserves fuel resources.

The second advantage of using a dual flush toilet is how it will help you save a lot of money in the long run. One dual flush toilet saves approximately 4,000 gallons of water per year and you will see that reflected in your utility bills.

The final advantages of dual flush toilets are how they need less maintenance and how they are a terrific time and energy-saver. They significantly clog less compared to older brands of toilets and some dual flush toilets are even self-cleaning. Instead of doing toilet related repairs and cleaning, you get to spend your irreplaceable time on more important things.

We have prepared a comprehensive Best Dual Flush Toilet Buyer’s Guide for you here:

Best Dual Flush Toilet Buyer’s Guide

Minimal water consumption

Water efficiency should be one of the main reasons why you should consider getting your own dual flush toilet. Always look for toilets with a low gallon per flush. The lower, the better. In fact, four US states require toilets to use 1.28 gallons per flush. These states are California, Colorado, Georgia and Texas.

A WaterSense certified toilet is a good option for water conservation and saving money in the long term.


A dual flush toilet is definitely a great investment. You should not hold back too much when spending money on this particular product. It will be worth it and the returns will be bigger than the cost. Consider your budget and what you can afford. If you are on a tight budget, then choose one whose basic features are satisfactory. These include the power of the flush, the material of the toilet and water consumption per flush. If you have more money to spare, then you can choose a unit with more advanced features.These include, but are not limited to, remote control, adjustable seat temperature, self-cleaning features and dryers.

The proper height

Standards set by the Americans with Disabilities Act (ADA) have bowl heights that are at least 16 inches tall. Adding the toilet seat will make them between 17 and 19 inches tall. Most commercial establishments follow this standard and they are ideal for taller adults. On the other hand, if your household is without a very tall adult, you can go for a shorter bowl. Our recommended height is 14.5 to 15.5 inches. Keep in mind that toilet seats add another inch or two.

The height of any seat will will either please or annoy you whenever you use the toilet. Although there is a universal height feature on most dual flush toilets, you have to be meticulous when buying a toilet. This is especially important if you have any physical conditions, for example, a knee problem. If a toilet seat is too low, it will be difficult to stand up once you sit.  And if a seat is too high, you will not be comfortable.

ADA Compliant Toilets are great choices for people with disabilities and the elderly.

Large flush valves

Bigger flush valves remove more solid waste with each flush. Standard flush valves are usually 2 inches in diameter, but newer models offer 3-inch to 4-inch flush valves for a better solid waste removal performance.

The size of the trapways

Similar to the concept of flush valves, wider trapways allow more waste to exit with every flush. Our recommended measurement is 2.125 inches or more.

Neutral colors

Most toilets are colored white or beige but some come in a wide variety of colors to match any taste. But give much thought to the toilet’s color before you buy one. Real estate professionals came to the conclusion that a toilet in a non-standard color can make your home harder to sell.

Do you live in a state with HET requirements?

California, Colorado, Georgia and Texas have firm policies that only allow HETs (High-Efficiency Toilets) to be installed. For safety, make sure that the dual flush toilet you wish to purchase meets HET standards. Additionally, a HET toilet may also qualify for a rebate from your local water utility which can cover a nice portion of your toilet purchase. The EPA website has a list of participating water utility organizations. The thing to remember here is that you may incur a penalty if you install a non-compliant toilet in your home.

A High Efficiency Toilet may qualify for a water rebate in your state.

One-Piece, Two-Piece And Wall-Hung Type

Most dual flush toilets come in two types: one-piece and two-piece. The two-piece toilet is more common. In a two-piece design, the bowl and the tank are separate and have to be joined together. The two-piece toilet design is usually the less expensive option.

But these days, the one-piece design is becoming more popular among many households. Because there is no seam between the tank and the bowl, cleaning is easier and it has a sleek look. Also, unlike the two-piece setup, the one-piece toilet type needs no assembly and putting together. The wall-hung design is the final type of toilet. This type is relatively new in the market and adds a unique twist on older version of toilets. This type of toilet has a separate carrier tank and it needs to be installed inside your wall. If you prefer this type of toilet, you should modify your plumbing system.

One-Piece Toilet – Easier to clean. Two-Piece Toilet – Cheaper. Wall-Hung Toilet – Space saving and easy to clean.

Size and shape

Dual flush toilet bowls come in two shapes, namely round and elongated. Those circular in shape are the round bowls and those oval or rectangular in shape are the elongated bowls.  Elongated bowls provide more comfort for adults while round bowls are more ideal for children. In most cases, circular toilet bowls are two inches shorter versus elongated toilet bowls. Generally, round toilet bowls are 16–17 inches long and those with the elongated shape are 18–19 inches long. Also, round-shaped toilets take up less space than elongated-shaped toilets so they are ideal for small spaces. They also cost less. On the other hand, elongated toilets provide more comfort thanks to the extra inches. Due to innovation from brilliant minds, hybrid bowls are now available which combine the best features of both types of toilet bowls. Hybrid bowls’ compact oval shape save a lot of space while giving extra comfort.

Round bowls are smaller and good for small spaces.  Elongated bowls are larger and more comfortable for adults.

Pressure assisted flush system and gravity flush system

Fierce competition has given birth to various mechanisms for flushing technology. The flushing system is easily the most vital duty of dual flush toilets. The two types of flush systems available are the pressure assisted flush system and gravity flush system. As the name implies, in a pressure assisted flush system, pressurized air pushes water into the bowl. A combination of water and high-pressure air is utilized to accomplish this.  Every time you flush, the pressurized air flushes the waste down with a very strong force. This method makes a noisy flush and is not cheap; however, this system is more efficient and less water is consumed.

The more common and simple mechanism is the gravity flush system. This method consists of a flush valve which relies on gravity and utilizes the water weight to produce a  flushing pressure. The waste goes through an S-shaped pipe, then a siphon completes the flush. This system is cheaper versus the pressure assisted flush system and does not create a lot of noise during flushing.

Pressurized Flush Systems are more powerful than Gravity Flush Systems, however they may be a little noisier and more expensive.

Rough-in size

A toilet’s rough in is the distance from the wall to the outlet pipe where the waste leaves the toilet. Toilets are designed to fit with rough-ins of specific sizes. Make sure that your toilet rough in size is compatible with the toilet model that you are about to buy.

Does the dual flush toilet have a lever?

Depending upon the setup of your bathroom, you will probably need the trip lever to be located on one side or the other. Most manufacturers offer models with a right- or left-sided trip lever location. Order the one that matches the layout of your bathroom so the lever is always within your reach.

Does the dual flush toilet have a push button?

A big number of dual flush toilets have a two-button flushing mechanism found at the top of the toilet. Many owners prefer this over the lever type, saying it seems more modern. But others claim that the buttons are tricky for the very young or very old to press. Also, the toilet top can’t store things like toilet papers which displeases some people. If you think that a push button toilet cannot meet your needs, stick with dual flush toilets that use a lever.

Final Thoughts

The reviews we’ve shared contain the brands and models which we believe every household would benefit having.
