Just think about the advantages that a new and efficient toilet can offer.

You might want to go for the best  toilet you can get your hands on.

The following article will widen you knowledge about the best dual flush toilet and also help you to choose the best one that suitable for your own bathroom. Let’s take a closer look!

What is a Dual Flush Toilet?

American industrial designer Victor Papanek was proposed the system in his 1976 book Design for the real world. Beside that, the first practical implementation was designed by staff at the Australian sanitary-ware company Caroma in 1980. Although the first generation caught on, a redesign of dual-flush toilet in 1993 cut water usage in half compared with traditional toilets, when used properly. The dual-flush toilet has been widely used in Australia, New Zealand, Singapore and Israel (often mandated by legislation in those countries). However, due to the more complex mechanism, it is more expensive than many other types of low-flush toilets.

A dual-flush toilet is a variation of the flush toilet that uses two buttons or handles to flush different amounts of water. This style of toilet is one of the most popular items among people who are trying to reduce water usage. Think about how many times you go to the bathroom in a day, especially if you’re drinking as much water as you should. Each time you make a bathroom trip just to pee, you’re wasting water if you use the same flush as when you’re taking #2 trip. So, these thrones give you two options to choose from, so you can decide how much water you actually need when you are using it.

Usually they feature two buttons on the top of the tank, one for liquid waste and one for solid. The first button releases a reduced volume of water for liquids, and the second releases a larger volume to flush solids, which is more like a conventional fixture. You are conserving water without actually compromising on sanitation or convenience!

During our research, we compared, tested and evaluated numerous toilet models and specifications. We even go through all the available feedbacks to help you narrow down your search for the best one.

However, you need to be very careful while choosing the dual flush toilet for you own bathroom. Installing a lower quality one might require you to flush twice and sometimes even thrice. This defeats the entire purpose of installing a toilet that reduces your environmental footprint.

This has been found to result in the use of less chemicals and water when it comes to cleaning. Moreover, it gives the toilet a shiny look all the times. To make sure the tankless toilet is suitable for adults and young children, it comes in a universal height. As a wall hung toilet, it can be paired with TOTO in-wall tank system plus other brands. This enables you to take the advantage of water when the pressure is too low or it is temporarily not available at a moment.

Tips: The wall mount toilet may not support the weight of every individual. This would result in the toilet being loose at the wall causing it to creak when sat on.

#3.American Standard 2889218.020 H2Option Siphonic Dual Flush Normal - an HET (High-Efficiency Toilet) in accordance with the Water Sense specifications for dual flush toilets

This could be a compact and affordable choice to those working with a medium budget. Not overly expensive but still contains some nice features and made by a reputable brand. It has a full flush of 1.6 gallons per flush and a partial flush of 1 gallon per flush. All the toilets are 100% flush tested at the factory and the whole toilet has a 5 year limited warranty. Due to the round shape and the overall height to the toilet seat (which must be purchased separately), this toilet does not meet ADA specifications. Toilets that do not meet ADA requirements cannot be fitted to new or refurbished restrooms that are used by employees or the general public. Two piece design, meaning the tank and bowl need to be attached to one another. A white color is not particularly unique, but that is a color we highly recommend over many other options out there, simply because it is so versatile at matching different themes.

Furthermore, it has been called the H2Options thanks to the two power levels that are operated via usage of button actuators on top of its tank lid. The lower flow will produce 0.92 gallons, while the stronger will send 1.28 gallons through the bowl. This means both fit WaterSense standards, which can enable people to make savings of around twenty percent compared to federal standard of 1.6. The bowl features something known as EverClean antimicrobial surface coating which stops things such as mold, odors and stains from the toilet by halting the growth of bacteria. Those of you who set high standards of hygiene for the bathroom, will appreciate this. It also has an easy connect feature which reduces its installation time by approximately 30 percent. And because it is easy to set up, you do not need to go through the hassle of hiring a contractor.


#4. TOTO CST412MF.01 Aquia Dual Flush Elongated Two-Piece Toilet

The TOTO Aquia is a close coupled and two piece that is made in vitreous china and finished in a cotton color. Instead of the traditional trip lever you find on most older loos, this one includes a chrome button on top of its tank that are used to trigger either of the two flushes. When combined with the skirted style mentioned previously, it has a contemporary feel to it that I believe many consumers will appreciate.

This dual flushing toilet will gives you two separate power buttons that will send either 1.6 or 0.9 gallons through the valve into the bowl. While the 0.9 option meets WaterSense requirements, the 1.6 does not. The lesser amount is usually used to remove liquid waste, and the larger amount for getting rid of solid waste that requires a little bit more power.

The toilet with a seat (which must be purchased separately) is what TOTO refer to as ‘universal height’. This means that the shape and height of the seat meet the requirements of the ADA specifications, but due to having a flush triggered by buttons rather than a lever, the toilet is not fully compliant. An elongated shape that is skirted and hides the trapway effectively, boosting the overall aesthetics. The smoother surface can also be beneficial in keeping it clean and hygienic as there is less cracks, nooks and cranies for dirt, bacteria and dust to build up inside. It is taller than your standard size too improving accessibility for people who find it hard to sit down.

By spending time to researching products, we have come across several of the best rated TOTO toilets on the market. This might not the most efficient unit out there but in my opinion, the CST412MF.01 model is another one that absolutely deserves to show up our guiding list.

Tips: 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.

#5. TOTO MS992CUMFG#01 Neorest 1.0 GPF and 0.8 GPF 700H Dual Flush

Although not as popular as some other models, the Swiss Madison SM-1T254 St. Tropez One Piece has a lot of great pros about it.


#8. SANIFLO SANICOMPACT TOILET.

This type of toilet 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. It has 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. Instead of a conventional flushing system, 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 Saniflo Sanicompact does not have a traditional tank which makes it look smaller but it sits like a normal toilet. The pump and grinder are concealed under the base of the toilet and we are very happy with the fit and finish of the product. When you flush there is a sump-pump like sound afterwards (it is an up-flush so it pumps the water up to the discharge line) and it has plenty of power. The sink also drains into the pump so when you run the water the pump kicks in afterwards. This is an option so if you do not need to drain a sink as well this model will still work for you.

On the other hand, there is a little more complex to install than a standard flush toilet. If it is a new installation, rather than a replacement macerating toilet, there is a likelihood that you will need to run a 1” pipe from the toilet to the waste pipe, which can be a little involved depending on the route that the pipe has to follow. That being said, the installation of the toilet, even including the option to use the toilet to get rid of waste water from a sink, is quite straightforward. An electrical outlet is needed nearby to provide power to the pump and macerator. Saniflo installation instructions explain all the steps. The electrical outlet used to power the toilet should be connected to a ground to reduce the risk of electric shock. The manufacturer recommend using a plumbing professional for installation.
