What is a Dual Flush Toilet?

A dual flush toilet, as the same suggests, comes with two flushing options that include a half flush for liquid waste and a full flush for solid waste. The dual flush mechanism has been quite popular in Europe and has been gaining traction in the U.S. over the past couple of years. The prime advantage of a dual flush is its water-saving capability that can help you save gallons of water per year per toilet and also reduce your annual water bills.

 

Every half flush uses 35% lesser water compared to a full flush and with modern technology, even the full flush uses less water compared to the old toilets that used 3.5 gallons per flush. In fact, today, some states have made it mandatory to use low-flow toilets. The federal regulations have also set 1.6 GPF as the maximum limit for the new toilets.

 

The best dual flush toilets that you find in the market today use 1.28 to 1.6 GPF for a full flush and 0.8 to 1.0 GPF for half flush. Most of the top rated dual flush toilets sport two buttons on the top of the tank lid, however, few models also come with a trip lever. However, the low water-consumption needs to be coupled with a strong flushing mechanism else you might end up flushing twice or thrice, which ultimately defeats the entire purpose of a dual-flush toilet. With that thought in mind, let us proceed to our top 6 dual flush toilet reviews.

Things to Consider When Buying a Dual Flush Toilet

We all want the best toilet but what defines the best is something that most of the users falter at. To take the confusion out of the equation, here are the essential features that you must make a note of while heading out to select the best dual flush toilet.

 

 

Configuration

The best rated dual flush toilets are available in one-piece, two-piece, and wall-hung designs. The two-piece models are cheaper and more commonly found. The one-piece design is gaining popularity as they are easier to clean. They are also quicker to install. There is also a third type, the wall-hung models that come with a separate career tank which needs to be installed inside the wall. They are the most expensive and you will also need to modify your plumbing system, which further adds to the cost.

 

 

Shape and Size

You can choose between round or elongated bowls according to your comfort. The round bowls take up lesser space, therefore, are more suitable for smaller bathrooms. The elongated bowls offer more comfort due to extra legroom but they occupy more space. You can also find hybrids that feature a compact elongated bowl but they take up the same space as a round toilet, e.g. WOODBRIDGE T-0019. You can also go for a square-shaped seat that is more modern in look and feel, e.g. WOODBRIDGE T-0020. While selecting the toilet you must also keep the rough-in measurement in mind.

 

 

Flushing Mechanism

The top rated dual flush toilets sport different flushing mechanisms with company patented technology. TOTO offers a powerful TORNADO flushing mechanism, while KOHLER is famous for its Class Five Flushing system. Also, you can choose between gravity-fed toilets and pressure-assisted toilets. The gravity-fed ones are more common and they make lesser noise. The pressure-assisted ones use compressed air along with water to flush out the waste. These models are more expensive and are also louder.

 

 

Buttons vs. Handle

The majority of dual-flush toilets come with dual flush buttons located on the top of the tank. However, keeping up with user demand, companies have also started integrating dual flush options in trip levers. One added-advantage of a trip lever is that you can use the top of the tank as extra storage space.

 

 

Toilet Height

Best rated dual flush toilets are available in the seat height range of 15” to 20”. However, the taller comfort height seating is more preferable for all kinds of users, especially for people with disabilities.  But you can go for the standard height if you have shorter people or kids in your family.

 

 

Warranty coverage

Since toilets are expensive bathroom fixtures, you should look for a model with a longer warranty cover. Also, you must read their warranty terms carefully before purchasing the toilet so that you don’t have to struggle with replacements later.

 

 

Budget

The average cost of the best rated dual flush toilets will fall between $200 to $800, excluding the bidet models. How much are you willing to pay for the best dual flush toilet is a very personal choice. You must also factor in the shipping and installation cost before selecting a model. Though the one-piece toilets are more expensive, they do have certain advantages like more durability, quicker installation, easy maintenance, etc. More the features more would be the cost, but you need to decide if the features are worth it.

 

 

Types of Dual Flush Toilets

The best rated dual flush toilets fall under three major types: one piece vs. two piece, and wall hung.

  1. Two-Piece Toilets: These are the more commonly found toilets where the bowl and tank come separately and need to be joined together at the time of installation. The two-piece models are preferred by households as they are cheaper and also easier to install. It is also easier to find their spare parts.
  2. One-Piece Toilets: The name is self-explanatory, these toilets come as a single unit and are easier to clean as there are no joints between the tank and the bowl. However, they are more expensive than the two-piece models. Plus, it can be difficult to install these heavier units single-handedly.
  3. Wall-Hung Toilets: These toilets are more modern in looks and they take up lesser space, keeping the floor space free. However, they are quite expensive and the installation is also cumbersome and costly.

 

 

Frequently Asked Questions

Ques 1. What is the difference between a single flush and dual flush toilet?

Ans: The single flush toilets come with one flush mechanism which means that the same amount of water will be released for both solid and liquid waste. This leads to excess use of water. The dual flush toilets, on the other hand, have two flush mechanisms that release two different quantities of water depending on your need. This functionality helps to save more water as you need lesser water to flush out liquid waste.

 

 

Ques 2. How does a dual flush toilet work?

Ans: The dual flush toilets have a specialized cylindrical flush valve, instead of a flapper, that releases two different amounts of water, based on the button that you push. Most of the dual flush toilets have two buttons where the smaller button corresponds to half flush and the larger button is for a full flush. The dual flush toilets also have a larger trapway that helps in pushing down the waste into the drain using lesser water.

 

 

Ques 3. Are dual flush toilets worth it?

Ans: In our opinion and also according to the best dual flush toilets consumer reports, these toilets are completely worth it. Firstly, you will do the environment a favor by reducing your carbon footprint. You will be saving gallons of water every year, which means reduced water bills. You can even earn water rebates in some states by installing a low-flow toilet.

 

 

Ques 4. Are dual flush toilets more expensive?

Ans: We will not deny; the top rated dual flush toilets are certainly more expensive than the standard toilets. However, they prove to be economical in the long run. Though their initial cost is higher, they last longer and also help to save on your water bills.

 

 

Ques 5. Is a single flush or dual flush toilet better?

Ans: If it comes to saving water, the dual-flush toilets are hands down a more viable option. They are eco-friendly and can help you save up to 70% more water than single-flush toilets. However, the flushing performance can vary as certain dual flush toilets are unable to clear out the entire solid waste in one go. But the same problem can also arise in standard toilets.
