Aside from kitchen and bedrooms, bathroom is the most essential place we have in our home, right? For hygienic reason no one can live without it. While the toilet bowl is our throne every time there’s call of nature.

Though, some people prefer the traditional single flush toilet while others are choosing the dual flush toilets. Is the dual flush toilet better in anyway than the a single flush toilet? This is what we are going to discuss in this article plus some of the best dual flush on the market today.

Which is better dual flush vs single flush toilets?

There’s a lot of arguing for a single flush and dual flush toilet, the question is which one is better? That’s what we are going to answer to make it clearer for you and easy to understand.

Let’s talk about the single flushing toilet system first. Single flush toilet has the advantage of being dead simple to operate. It has a single flush lever on its side most likely located on the side of the toilet’s tank. You don’t need to choose which one you should be using when it is time to flush the bowl because there’s only one lever is present.

However, you always use the maximum amount of water every time you flush it. It doesn’t matter if it’s a light or heavy waste you’re going to flush. Therefore, you tend to waste more water with the single flush toilet.

On the other hand, in the case of a dual flushing toilet system it gives you choices from heavy and light flushes. For removing maximum bulk of waste you may want to use the heavy flush button. While the light flush button takes care of small waste and urine.

That being said, a dual flushing toilet system saves you more water while a single flushing toilet system you tend to waste more water as it always use the maximum amount of water even for light waste.

From this point, you can see the huge advantage of a dual flushing toilet system compare to a single flush only.

Pros and cons of single flush vs dual flush toilets?

Ease Of Use

Single flush toilets are easier to use due to a single lever push down activation. While some individuals find the dual flush not user friendly which leads to confusion which button is to be push for half or full flush.

Dual flush buttons are located on top of the toilet tank and requires extra force to activate which some elderly persons find it more difficult.

Moreover, some users don’t want the push button and prefers the traditional single lever activation. However, almost all dual flush toilets have an indicator for half flush and full flush for you to easily identify it.

The Verdict: If you want a dead simple to operate you probably stick to traditional single flush toilets. If the dual flush toilet doesn’t confuse you then go for it as it gives you more advantages.


The cost of a dual flush toilet is a bit higher than the single flush although, some good brand offers more affordable price dual flush toilets. The parts for single flush are cheaper and easier to find which is more common. On the other hand, dual flush toilet parts are pricey and more complicated to install.

The Verdict: Single flush toilet is cheaper. If you want to save money on parts and labor single flush is a way to go.

Environmental Friendly

Dual flush toilet is definitely an environmental friendly. Single flush toilets tend to waste too much water as it always uses maximum water consumption every time you flush. This will also hurt your pocket with your monthly water bill. In the long run the single flush toilet will cost you more than a dual flush toilet, right?

The Verdict: Dual flush toilet wins.

Do dual flush toilets save money?

The answer is absolutely yes, as I stated earlier single flush always use its maximum flushing water while the dual flush toilet enables you to choose between light and heavy flushes. For an average household tend to flush 4,000 to 5,000 times per year.

Therefore, it consumes 6,400 to 8,000 gallons of water considering a standard 1.6 GPF (Gallon Per Flush) single flush toilet. Using this simple formula (4,000 x 1.6 = 6,400-gal) to get the yearly water consumption.

However, most of the time you and your family members are using the light flushes only for urinal purposes, right? A dual flush toilet system with 1.6 and 0.8GPF water consumption and considering half of the time you are using the light flush while heavy flush on the other half.

You’re water consumption will cut down to only 4,800 gallon per year instead of 6,400 gal. How we get that? Splitting the 4,000 flushing times into half that was 2,000 x 0.8 gal (half flush) = 1,600-gal and 2,000 x 1.6 gal (full flush) = 3,200 gal then to sum it up 1,600 + 3,200 = 4,800 gal. Instead of 6,400 gal of water your consumption is cut down to only 4,800 gal. This will further be lowered as you frequently use the light flushes most of the time.

As a result, you will save more than 1,600 gal of water every year that will definitely cut your monthly water bill.

How much water do toilets use?

Household toilets uses significant amount of water that was estimated with more than 30% of total water consumption inside your home. Therefore, deciding to choose an ideal toilet for your home is crucial. This will reflect on your additional monthly expenses for water usage only.

Older toilet uses 3 to 5 gallons of water per flush but, some are even 6 gal. If you still using those vintage toilet at home you’ll never know how much water you are wasting. This is the reason why the US federal set a standard for toilets with maximum of 1.6 GPF (Gallon Per Flush).

Modern toilets now are using the low flow or HET (High Efficient Toilet) to further save you more water. It means that, these low flow toilets are using less than 1.6 GPF such as 1.28 GPF or even as low as 1 GPF.

An average person at home flushes 5 times per day but, most commonly more that. Therefore, if you’re using a 1.6 GPF toilet you have to multiply it by 5 and that was 8-gal. In one month you got 240-gal (30 x 8 = 240gal). In one year you have 2,920 gal (8 x 365 2,920).

If you have 6 family members at home you have to multiply the daily, monthly and yearly by 6. For daily 8-gal x 6 = 48-gal, monthly 240-gal x 6 = 1,440-gal, and yearly 2,920-gal x 6 = 17,520-gal.

This is how much water your toilets are using. If you are using a low flow toilet such as the 1.28 GPF and 1 GPF your water consumption will further lessens.
