What Is a Dual Flush Toilet?
A dual-flush toilet uses two buttons or a handle to flush different amounts of water. The TOTO-style hand-washing system was first introduced in 1960. It was the first system to feature a built-in hand-washer. In 1976, American designer Victor Papanek suggested the dual flush system, which uses both a low and high flush. The system was first implemented in 1980 by Australian company Caroma.
The dual-flush toilet has become widely used in several countries, such as Australia, Singapore, and Israel. Its simplicity and cost-effectiveness make it an excellent choice for new buildings.
Pros & Cons of a Dual Flush Toilet
As with every other product in the world, dual flush toilets brings forth a series of advantages, but also some drawbacks that every customer should know about in order to establish whether these toilets are the right choice for them:
Pro: They save water. This is one of the biggest advantages of owning a dual flush toilet. We don’t want to get into the specifics that we already talked about in this article, but we’re going to underline the fact that a dual flush toilet allows you to use less water for flushing liquids, and that’s something that a traditional single flush model can’t do.
Con: They’re expensive. Yes, dual flush toilets cost more (the product and the installation are both expensive compared to getting a regular toilet up and running).
Pro: They don’t clog as much. That’s because they use gravity to aid in waste removal and are designed with a large trap-way to be more efficient in this area. This eventually leads to fewer clogs compared to those you get to experience when you own a traditional toilet down.
Con: They are more difficult to clean. With every flush, these toilets will have less water in the bowl, making them look dirtier compared to traditional models. Unless you opt for a smart self-cleaning dual flush toilet, you’re going to have to clean the bowl more often.
Pro: They have more powerful flushes. If you invest in a highly-efficient model, you will be the owner of a toilet with a very powerful flushing mechanism that you only have to use when necessary.
Types of Dual Flush Toilets
There is more than just one type of dual flush toilet available out there, and here are the three main categories that you’re bound to come across.
In contrast to the more usual two-piece toilet, which comes with a separated bowl and tank, a one-piece toilet has these two components merged into a single unit. Despite the fact that two-piece toilets are more widespread, one-piece toilets are gaining popularity due to their distinct advantages. To begin with, one-piece toilets are simpler to clean. Because they don’t have as many nooks and crannies compared to two-piece systems, bacteria and germs have less room to hide. They also have a sleeker appearance that may go in better with the current decor in a modern bathroom. One-piece toilets have internal components that are less likely to leak and don’t require that many repairs in the long run. They also tend to be heavier, more difficult to install and maintain, and more expensive. The aesthetic appeal, simplicity of cleaning, and the enhanced durability, on the other hand, may compensate for the heavier weight and higher price.

The most common toilet design is a two-piece toilet. It is made up of two parts: the tank and the bowl. Some of the advantages that this model brings forth is the ease of repair and the ease of moving, compared to a single-piece. Because the parts are more accessible, these toilets aren’t as durable. Two-piece toilets have the advantage of being available in a variety of sizes and shapes. As a result, they can accommodate a greater range of interior design elements and bathroom areas. They’re also usually less expensive than one-piece toilets.
The two models we looked at earlier are considered floor-mounted, but there is another option worth considering and that category is represented by wall-mounted toilets. As opposed to floor-mounted models, this one comes with its components hidden inside the wall. As a result, you have about 10 extra inches of small space to work it, making these models particularly suitable for small bathrooms. The bowl is also suspended from the wall, leaving free space beneath it. This feature makes your bathroom floor more accessible and, therefore, easier to clean. You can also modify the floor-to-seat height with wall-hung toilets, which can be installed from 15 to 19 inches above the floor. They are typically more costly, more difficult to maintain, and more complex to install than their floor-mounted equivalents.

How to Choose a Dual Flush Toilet for Your Home
If you’re ready to make the transition from a single flush to a dual flush toilet, here are the main features that you need to look for in order to determine which products are best suited for your needs:
The majority of dual flush toilets are composed of plastic or porcelain. The most prevalent material used in the manufacture of toilets is porcelain. This is due to the fact that porcelain is durable, provides a watertight seal, and the manufacturing process isn’t that expensive. Plastic toilets aren’t that common due to the difficulty of producing a plastic that is equal to porcelain in terms of quality.
White is the most common toilet color you’re going to find because it’s a pretty standard choice that matches almost every bathroom style and design out there. Naturally, there are also other color and finish options, but if you have a white bathroom sink, paring it with a chrome toilet isn’t exactly recommended. In terms of colors, you want to choose something that matches the rest of your bathroom decor.
Round bowls are more compact and less expensive than their elongated counterparts. That makes them a better choice for a smaller bathroom where you want to maximize floor space as much as possible. To comply with the Americans with Disabilities Act (ADA) rules, most construction codes demand the existence of a minimum of 21 inches of floor space in front of the toilet.
The two most common shapes for toilet bowls are round and elongated. Round toilets are not as expensive as elongated models, as the latter are generally considered to be more comfortable. Elongated toilets are the most popular since they provide more comfort, which is why they are often advised for bathrooms with enough space.
Dual flush toilets are distinguished by their flushing mechanism. Unlike the standard single flush model, dual flush toilets use two types of flushes to get rid of solid and liquid waste. Liquid flushing utilizes about half the amount of water that solid waste flushing does. This nearly-gallon-per-flush figure can save thousands of gallons of water annually. Toilets that have a dual flush mechanism do so due to a particular flush valve that limits the volume of water exiting the tank. On the other hand, single flush toilets will remove all the water from the tank each time you flush.
Did you know that about 30 percent of the water you use in your home every day goes into flushing the toilet? In other words, it is the main source of water consumption in your home. Most healthy people dispose of liquid waste three to four times more frequently than solid waste, but they use nearly twice as much water to do it. You can stop wasting water by installing a dual flush toilet. When you use the flushing mechanism that uses less water, you can save up to 67 percent more water compared to people that use a single flush toilet with the same amount of water usage each time they flush.
The starting price for a decent dual flush toilet is $150, but to get a really good price-to-quality ratio, you have to be willing to spend about $250 to $350 (naturally, there are toilets that are even more expensive). The installation cost for dual flush toilets is between $200 and $350.
Dual VS Single Flush
If you ask pretty much anyone to name the two main categories of toilets they know about, most people would label them as single or dual flush. But what are the differences between these two types of toilets, exactly?
The most prevalent form of toilet found in old homes is the single-flush model. The name derives from the fact that these units come with a single flushing mechanism that uses all the water in the tank regardless of the waste the needs flushing (which can be up to five gallons).
Dual flush toilets have two of these mechanisms which are typically represented by two buttons located on the top of the tank. One button activates a flush that uses less water (about 0.8 gallons) and is exclusively for liquid waste, while the other activates a flush that is for solid waste (about 1.6 gallons).
Because they have fewer parts, single flush toilets are typically cheaper to repair when parts of them break down. Furthermore, some people believe that it’s more difficult to use a dual flush toilet because the buttons that one needs to press to flush the toilet are one next to another, relatively small, and require more pressure to push. On the other hand, dual flush toilets consume way less water, which is more cost-effective in the long run.

Is a dual flush toilet worth it?
Yes. A dual flush toilet consumes way less water in a 24-hour span compared to a single flush model. When you use a traditional toilet, you are using the same amount of water for liquid and solid waste, which isn’t necessary. A dual flush toilet helps prevent that and uses less water when there’s not that much waste to flush.
What happens if you push both buttons on a dual flush toilet?
Pushing both flush buttons at the same time will lead to a larger water consumption and water being released with a lot of pressure.
Which is better single or dual flush toilets?
Even if dual flush toilets are more expensive and cost more to repair in case of damage, they also save up a considerable amount of water. To determine which is better, you’re going to have to prioritize what it is you hope to obtain from such a product.
There are plenty of reasons why you should choose a dual flush toilet. Even if it requires a higher upfront investment (even installation costs more for these models), it can help save a lot of water. When you look at the statistics, it’s troublesome to think about how much water is wasted when using a single flush model, so investing in a dual flush toilet seems like the responsible thing to do.
