Best Dual Flush Toilets Reviews

This is the best dual flush toilet reviews there is:

American Standard H2Option

No list of best toilets would be complete without an American Standard toilet. The dual-flush mechanism works smoothly and it’s very quiet, which certainly is a huge bonus. Because the flush mechanism works so well, the bowl will be cleaner (compared to other models).

Moreover, this model is a breeze to install and takes a little time. The unit complies with ADA specifications and is also WaterSense certified. Meaning, it won’t use more than 1.28 gallons of water per flush – so you’ll definitely reduce water consumption in your household.

As for the downside, the model doesn’t come with a seat, so you’ll have to spend some extra cash in order to get one.


Woodbridge Dual Flush

The Woodbridge Dual Flush toilet is one of the most popular dual flush toilets on Amazon. It is equipped with an elongated seat and is ADA, or a comfort height toilet.

It also includes a soft-close toilet which most consumers really appreciate. It has a very sleek and modern design that will look great in any bathroom. The Woodbridge is equipped with a siphon flushing system so that no waste is left behind. You can choose from a 1.0 or 1.6 gpf depending on if you are depositing liquid or waste, giving an average of 1.28 gpf.

This all-in-one package includes the toilet, pre-installed toilet seat, wax ring, floor bolts and instructions for installation.​


TOTO Neorest 550

Now, if you are fine with spending a fortune on a toilet, then this is the way to go. This model comes with all the bells and whistles – Programmable Nightlight, Automatic Flush, Automatic Open and Close Lid.

You’ll be impressed with it and, without a doubt, will love using it (and so will your friends and family). This toilet makes effortless work of using a toilet, as it has an automatic flush and automatic lid. We love the provided light, as it looks really great at night. Plus, it comes in handy.

However, you may need to change the plumbing in the bathroom, in order for this unit to be installed properly. Needless to say, this is not a small thing to do, though this toilet works fantastic.


Kohler Wellworth

In case you have a small bathroom, this toilet will be an ideal fit, thanks to a round-front bowl. This model offers the possibility to flush 1.1 or 1.6 gallons of water per use.

It’s a two-piece model, making installation a whole lot easier. This toilet is well-built, efficient and quiet – plus it comes at a great price.

As for the downside, the toilet is a bit low, so it can be inconvenient for the elderly.


TOTO Aquia dual flush toilet

Beautiful and functional – this model is one of the best dual-flush toilets that money can buy. Toto Aquia comes in a variety of colors to choose from so that you can find the perfect one to match your bathroom’s interior.

This toilet has universal height and features an elongated bowl, which looks more elegant than a rounded one. Despite nooks and cranks, you won’t have any problem with cleaning the toilet.

However, a slight issue is that chrome push-buttons tend to get stuck every now and then. But, this is a common issue with this type of toilets.


Saniflo Sanicompact Toilet

The Saniflo 023 SANICOMPACT is quite different to most standard toilets in that it uses macerating and a pump to remove waste, rather than flushing directly into the drainage system.

This makes the Sanicompact 48 an ideal solution to fitting a toilet in areas where a standard flush toilet is impractical.

A waste pipe from a sink can also be hooked up to the toilet making it an ideal solution to building a half bath in places where a standard toilet would be impractical. The pump on the toilet can pump up to 9 feet in height and 100 feet horizontally, all through a 1” pipe.

As mentioned above, the Sanicompact 48 does not use a conventional flushing system. Instead, once the flush button is pressed, the toilet fills itself with a set volume of water, then this, together with the waste, is drawn through macerating blades and pumped out through the 1” waste pipe.

The flushing system is explained in this video from Saniflo. Here is the full review on the Saniflo Sanicompact.

Toto Washlet with Integrated Toilet Model

This model is a compact, one-piece, skirted toilet and bidet combined. It is one of the very few dual flush toilets that meets all the requirements of ADA compliance.

Although other dual flush toilets meet the height and bowl specifications for ADA compliance, they do not meet the levered flush requirement. It overcomes this by having an automated flushing mechanism. It is a technology packed toilet in both the construction and electronically controlled features. The Washlet is Water Sense certified.

The toilet has Toto’s 3D Tornado flush system that uses a series of nozzles to increase the flushing capability of the toilet using minimal water. In combination with the ultra-smooth ceramic glaze, this helps keep the toilet cleaner for longer and minimizes the need for manual cleaning.

There is an automatic opening and closing of the lid, which then triggers the automatic flush. The seat is heated and the washing feature of the bidet can be adjusted for both direction and temperature.

These functions along with the variable warm air drying can be adjusted via the wireless remote control pad. Read the full review on the Toto Washlet with Integrated Toilet!

What is a Dual Flush Toilet?

A dual flush toilet is very similar to a single flush or regular flush toilet, the only difference is that, the dual flush toilet comes with two buttons/handles to choose between a lower or higher level of water consumption.

The “dual flush” that gives this toilet its name is the ability to choose a flush option for either solids or liquids; the solid waste flush option generally uses 1.6 gallons of water per flush (gpf), while the liquid waste option uses less than 1.1 gpf.

This means that dual flush toilets will comply with the standards necessary for WaterSense certification; in other words, they meet even the lowest flow criteria

The dual flush toilet has the ability to use both 3litres of water and 6litres of water, the first one is used for liquid waste while the latter is for solid waste.

You can use them in basement, small spaces, and offices and even in location where there is limited flow of water.

Dual flush toilets feature a larger trap way in the bowl, which ensures the bowl will be cleaned much better. This also means you won’t need to use very harsh chemicals in order to clean your new dual-flush toilet (and that the quality of the said toilet won’t be decreased).

The dual flush toilet makes use of gravity as against the single flush toilet use of water –siphoning method and this helps to prevent them from clogging easily, which saves you even more money.

Benefits of a Dual Flush toilet

Here are the major benefits of using a dual flush toilet in your home:

  • Reduces water consumption thanks to dual flushing system
  • Has a positive impact on the environment
  • Lowers water bills
  • Requires less maintenance

Best dual flush toilet buying guide and selection consideration

Before you make payment for the best dual flush toilet, you should consider the following considerations to make a better choice:

Appearance of the dual flush toilet

Think about which of these would match your bathroom decor, and your personal style! Be sure to consider angles vs. curved lines, ornate touches vs. simple lines, and so forth!

Remember that most models are offered in both rounded and elongated bowl shapes, so choose what works best for you!

Dimensions of the dual flush toilet

Make sure your new throne is at a comfortable height for you and your family! We try to include ADA-compliant fixtures in our guides, since they tend to be best for everybody.

However, if you don’t find standard ADA toilet heights comfortable, be sure to check measurements and make sure the seat will be appropriate for you.

Warranty coverage of the dual flush toilet

Get covered for the long term, so you don’t have to worry about replacements! Most thrones have generous coverage from the manufacturer.

However, on the more expensive options, extended coverage plans can be a smart buy.

Water usage of the dual flush toilet

Check the actual flow rates on our models, and see how much of a savings you can make! Remember that most dual-flush models use the standard 1.6 GPM for solid waste, so you’ll mostly be saving on your liquid waste removal.

That still adds up over the course of a day! If you want to be saving in both modes, though, look at something with a solid waste option that uses less than 1.6 GPM.

Flushing mechanism of the dual flush toilet

Find something that works best for you, traditional or modern! Do you want buttons, knobs, or something else?

There are lots of options! One way to narrow down your options is to decide how attached you are to being able to store things on top of your tank. If you are, you’ll probably want knobs instead of buttons.
