Fine Fixtures Dual Flush toilet is a high-quality one-piece toilet with dual flushing capabilities. The Dual-Flush has a 6 LPF (liter per flush or less) rating in terms of efficiency. The toilet’s high-grade structure includes a trapway and a glass surface.

The glass exterior of the toilet also contributes to keeping the bowl fresh between uses. The trapway does not become blocked since no residue is permitted to remain on the glazing substance. This toilet seat is quieter and less obtrusive than ordinary toilet seats, which can be unpleasant if they slam repeatedly. Because the lower portion of the toilet seat is soft, there is no sound when you close the lid.

The soft-closing toilet seat is suitable for families with little children. The dual flush saves water because it uses less than a single flush. With this flush, you can conserve a lot of water while still getting the job done. You’ll also save money on your water bill.

We’d recommend the Kohler K-3987 dual flush toilet for low-cost toilets. Aside from its low price, the almond-colored vitreous china on this item gives the toilet a wonderful appeal. It includes a Class 5 flushing system, which accounts for the flush’s excellent efficacy. This toilet also includes a big valve that allows fast water to flow through the direct-fed jet at high pressure, guaranteeing that the bowl is clean after each flush.

The toilet’s canister, which has a 90% uncapped seal material, ensures leak-proof functionality. The universal red seal is more durable and lasts longer since it is less exposed to the water in the tank.

The Benefits of Using a Dual-Flush Toilet

Factors to Consider While Choosing a Dual Flush Toilet


Remember that a high price tag doesn’t necessarily mean high performance when looking for a new product. According to users’ experience with dual flush vs. single flush toilet models, the ones in the middle of the pricing range are frequently the best. 

A long-lasting toilet built to last can save a significant quantity of water for many years. For this reason, it’s critical to consider these most critical factors while looking for a toilet: drain-line clog, waste removal, and bowl cleaning ability. The following steps outline how to determine a toilet’s efficacy once it has been installed:

Water efficiency

The most important issue for a dual flush toilet is water efficiency. The EPA has set the maximum flushing capacity for toilets at 1.6 gallons. You should look for flush toilets that use less than 1.6 gallons of water each time used. As an alternative, look for the WaterSense logo on the toilet tank. It is implied that a WaterSense-certified toilet meets the EPA’s standards for water efficiency, which will help you save funds on your water bill.

Noise level

Because a noisy toilet is annoying and inconvenient, no one wants to have one in their bathroom. The quietest flushing dual flush toilets are the best choice, so look for this feature before buying. An insufficient water flow in the bowl is frequently blamed for the clamor. Your toilet’s noise level may be an indication of poor construction. It can also be quite noisy when a firm toilet seat is used.

Easy of maintenance

The simplicity of maintenance is another important consideration. A toilet requires a lot of water, effort, and chemicals to clean and maintain. So, if it is difficult to maintain, then the whole point of a perfect dual flush toilet is lost. It’s also advantageous to have a toilet that requires little to no maintenance or cleaning, as doing so requires just a small amount of physical exertion. It may be used for a long period without considerable maintenance and also means that it is cost-effective and efficient to utilize.

Comfort level

The ease with which you can use a toilet has a lot to do with how comfortable it is. It’s safe to argue that an uncomfortably cramped toilet is a major annoyance, given its primary function. Before buying a toilet, you need to make sure that it’s comfy. Check the toilet’s height, size, and design to see if it suits your needs. Consider the size of your bathroom when deciding where to put the toilet.

Seat height

Your toilet’s height plays an important role in your comfort and convenience. As a result, no matter what style or design your toilet has, you should always keep its height in mind. Standard toilets sit around 15 inches above the floor. However, there are a variety of 18-inch-high comfort-height toilets on the market, which are often ADA-compliant. 

The goal of these toilets is to replicate the experience of sitting on a regular chair as closely as possible. This type of toilet is ideal for persons with mobility issues because of its enhanced height and comfort.

Size and shape

Elongated toilets and circular toilets are the two most popular shapes. The elongated variants are well-known for their comfort. Even though they take up more room, their square design offers a more comfortable sitting experience than their round counterparts. On the other hand, round toilets are typically 5 inches smaller and better for tiny children. Finally, if you have a small bathroom, a wall-mounted toilet is an excellent alternative because it can be quickly installed to maximize space.

The Benefits of Using a Dual-Flush Toilet

Municipalities first adopted dual flush toilets to cut costs and waste. Occasionally, you’d see the dual flush option at airports and public buildings. You can dispose of small waste (urine) by pressing one button, while you can dispose of larger trash by pressing another button. For a variety of reasons, dual flush toilets have become increasingly popular.

Reduce cost

First and foremost, they slashed costs. We said that older toilets typically utilize 3.5 to 7 liters of water for flushing purposes in the introduction. That works up to 16 flushes a day for a household of four people who each use the restroom four times a day. It will take 80 gallons of water to flush a 5-gallon tank.

Dual flush toilets use 0.8 gallons for urination and 1.28 gallons of bigger waste with each flush. A family of four uses only 20.48 gallons of water per day if they flush their toilets at 1.28 gallons every flush. That’s a 75% reduction in water consumption per day. That adds up to a significant amount of money saved for a month.


But money isn’t the only factor. A dual flush toilet can save a huge amount of water if you care about the environment. Our climate is changing in some manner, shape, or form. Water shortage is becoming an issue in the Western United States, where rain patterns are unpredictable, and droughts are growing more common. 

Desalination facilities improve water treatment plant efficiency (to recycle water), and grass removal is a method by which states, communities, and individuals reduce their water consumption. Every day, we defecate in freshwater, although many countries do not have access to fresh water or have to trek for miles in search of it.


In some U.S. states, dual flush toilets are also becoming more popular among homeowners due to government incentives and regulations. In several states, new residences must have WaterSense-certified toilets installed as standard (WaterSense is the certifying body for water-efficient toilets). As part of the regulatory approach to decrease waste and water use, it’s a sensible policy that makes sense (WaterSense).

The only exception is for existing homeowners who are exempt from this requirement. Homeowners benefit from rebates and other incentives to buy a new toilet at a reduced price. Family budgets benefit from the refund since it encourages them to replace out-of-date technology while saving water.

Dual flush toilets clog less

It is less probable that a dual flush toilet would clog. Gravity helps with trash collection, and a large trap-way is included in the design to make this process more efficient. There will be fewer clogs because of this compared with a regular toilet. Most dual flush toilets rely on gravity instead of pressure siphoning to flush waste away. As a bonus, the trapway’s size reduces the risk of clogging.


Using a dual flush toilet will save you money because it uses less water. If you think about it, the amount of water you consume on a monthly or annual basis determines your water bill. Because of this, a dual flush toilet can save you money in addition to your shallow baths and quick showers.

Factors We Considered While Choosing These Dual Flush Toilet Brands

Types of Toilet Flushing Systems

Gravity flush

Gravity-based flushing systems use the water’s weight to generate flushing pressure. In some gravity systems, an elevated cistern is used to extend the distance water must travel to the toilet bowl to optimize pressure and improve flushing efficiency. Cleans and removes trash from the bowl simultaneously with the help of the tank water. Since the beginning, toilets have relied on gravity for flushing, one of the oldest methods. They’re also one of the fastest flush systems available, thanks to the limited number of moving elements they contain.


A pressure-assisted system uses an additional mechanism to push water into the toilet bowl even more forcefully than a gravity flush. When water begins to fill the toilet’s ceramic tank, an air-filled balloon in a plastic tank is compressed. Because of the compressed air inside the balloon, flushes can pump water into the bowl at a higher flow rate than achievable in a gravity tank. 

These systems can use less water yet be strong or use the same amount of water more effectively than gravity flush systems. Pressure-assisted toilets are noisier than other flushing systems because of the additional force exerted during the flush. Some people may prefer a quieter, less powerful computer setup.

Dual flush

Environmentally friendly dual flush systems are increasingly popular since they let you use more or less water depending on the amount of trash you need to flush. It is possible to do a “full” or “partial” flush on the same toilet by using two levers or buttons mounted on the same piece of equipment. There is no difference in how much water is used while flushing the toilet with the full flush.

On the other hand, a half flush utilizes only 1.1 liters of water and is suited for liquid waste only. Because of its excellent water-saving qualities, many countries have embraced the dual flush system and require it to be included in all new buildings.

Double cyclone/tornado flush

TOTO, a toilet manufacturing firm, recently developed the “Tornado Flush” toilet technology. The Tornado Flush uses two enormous nozzles on either side of the bowl to create a centrifugal, cyclonic rinsing action instead of the typical rim holes. The same high-efficiency system handles solid and liquid waste, which requires just 1.28 gallons every flush.

Frequently Asked Questions

What is a dual flush toilet?

Toilets with a full flush and a low-flush option are called dual-flush toilets. Water conservation is the most important benefit of a dual flush toilet. As in Europe for decades, dual flush toilets are becoming increasingly popular in the United States. Toilets can take up to 26% of the water consumed in the United States in a year. If you have a dual flush toilet, you’ll save around a third of the water you would come with a standard flush.

On the other hand, modern toilets save a lot of water even with a full flush, compared to previous toilets. Compared to a modern high, efficient toilet, older grandfathered-in toilets can use up to 3.5 gallons of water per flush. One gallon or less is used for a partial flush, while one gallon or more is used per full flush on most modern dual-flush toilets. It’s now a federal rule that toilets cannot use more than 1.6 gallons per flush.

How does a dual flush toilet work?

A unique cylindrical flush valve used in dual flush toilets can accurately release two different volumes of water simultaneously. The flush button on most dual flush toilets will be two separate buttons. This button has a tiny button for liquids and a larger one for solids. It is not uncommon for dual flush toilets to include handles that can control how much water is flushed and how much is flushed completely. 

The light flush (0.8 to 1 gallons) and the full flush (1.2 to 1.6 gallons) typically flush about the same amount of water. Instead of using a rubber flapper, the basic single flush toilet now has a designed flush valve.

Which is better, single or dual flush toilets?

Dual flush toilets conserve water, but it can take some time to get used to them because of their unique design. Having to relearn how to operate buttons and levers might be difficult for some people. Additionally, these toilets are more pricey than their predecessors. On the other hand, dual flush toilets may necessitate more regular cleaning for some users. 

The dual flush toilet is a good alternative to lessen your environmental footprint. In addition to saving water, you may see a decrease in your water bills due to your efforts.

How to convert a single flush toilet to a dual flush toilet? 

To prevent water from overflowing, remove the tank cover and insert the dual flush valve on the toilet’s overflow duct. Afterward, remove the preceding lever and unscrew the corresponding pushbutton actuator. Attach the actuator to the dual-flush valve and secure it to the tube. Lastly, turn on the water supply shut-off valve, and you’re ready to go!

What is the right size of a dual flush toilet?

To begin, think about the height of the bowl. There will be a 15 to 17-inch gap between the bowl and the ground. Each product’s design, however, can differ slightly. For example, toilet bowls 17-19 inches high for the elderly, disabled, or wheelchair users are designed to make them easier. Alternatively, children’s toilet bowls are often less than 15 inches in diameter.

You’ll want to measure the bowl’s breadth and length. Dual-flush toilets come in various shapes and sizes, including round and elongated bowls — the diameter and length of a round bowl range from 14 to 15 inches. The elongated bowl has the same width as the circular bowl. Despite this, it’s a tad bit lengthier. The exact measurement of the elongated bowl’s length is between 18 and 19 inches.
