Tips & Tricks for Choosing the Best Toilet Flush System for Your Bathroom 

There’re some crucial tips to keep in mind whenever you’re shopping for a top flushing toilet. Remember, a toilet with bad features may translate to a bad experience during use, while one with exceptional features will definitely be easy and fun to use.

So, what is the best flushing toilet? Here I discuss the most essential features to consider so you can use them as a guide at the point of purchase.

  • Construction Material 

Most flushing toilets are constructed using porcelain or ceramic. From my experience and testing, I recommend porcelain and ceramic as they’re more durable and long lasting than other materials like plastic and vitreous china.

Although toilets made with these two materials are more expensive than their other counterparts, it’s totally worth it. Besides, toilets made of porcelain and ceramic look premium and elegant.

If you can’t afford a porcelain or ceramic toilet, I’d recommend that you settle for one made of vitreous china. This material comes in the third slot in my durability rating.

  • Flush Type

You can choose between the gravity flush and pressure assist flush system. On the one hand, the gravity flush option entails a flush valve which moves the waste from the toilet bowl down the drain using the force of gravity.

In this flush system, water comes from the tank and jets into the bowl where it eliminates urine and feces and moves them down the train.  Flush valve can range from 2 to 4 inches in measurement.

Beefy flush valves measuring above 3 inches deliver more powerful flushes.  Compared to pressure assist toilets, gravity flush toilets are more powerful and quiet, but they’re also easy to clog.

On the other hand, the pressure assist toilets move urine and feces down the drain using pressure.  Pressure-assisted toilets have a sealed tank that generates powerful pressure responsible for eliminating the waste.

For the pressure-assisted toilets to work, you must be having not less than 25 pounds per square inch of water pressure at home. You can determine the water pressure of your bathroom using a gauge that connects to an outdoor spigot.

The pressure assist flush toilet system is highly recommended for a large household, because it’s very efficient in removing solid waste. On the downside, this flush system is noisy and more expensive to install.

  • Rough-in Size 

A rough-in is a term in plumbing that describes the distance in between the back of your toilet and the wall, where there’s a large pipe allowing water to leave the bowl. The rough-in measurements for most standard toilets range from 10-14 inches.

Confirming your toilet rough-in isn’t a hard task provided you have a measuring tape.  Before measuring the rough-in, I recommend that you check the number of bolts on the side of the toilet which secure it to the floor.

If there are two bolts, find their exact center and measure from there toward the back wall. Measuring the rough-in may be a bit challenging if there’s only one bolt securing the toilet.

Place the measuring tape’s flat end directly against the back wall, making sure not to add in the molding or baseboard on the wall. Then, pull back the measuring tape until it reaches the exact center of the two bolts. That way, you’ll be able to determine your toilet rough-in size.

A rough-in plays a pivotal role in choosing the right flushing toilet, because you can’t buy a toilet whose rough-in size is 14 inches long when your toilet rough-in is only 10.  If your bathroom is modern or you’ve just renovated it, then you should go for between 10 and 12 inches rough-in size. 

  • Water Conservation Technology

According to research, a flushing toilet consumes an average of 30% of all the water in our homes. So why not purchase the best flush toilet equipped with the water saving technology?

To conserve as much water as possible and reduce your water bills, some manufacturers have created toilets that contain a Water Sense Label. Toilets that arrive with this technology are ADA approved, and can conserve the environment better.

A good toilet should consume no more than 1.28 gallons of water per a single flush. This helps minimize water usage per every session of a short call or a long call.

  • Dual Flush Technology

For added water conservation, I recommend opting for toilets with a dual-flush technology. While the classic single flush technology is cheaper, the dual-flush technology lets you save more in the long run.

The dual-flush technology is an advanced flushing system containing two buttons on the tank. This dual flush mechanism lets you use less water to remove urine and more water to move solid waste to the drain.

Using the two different flushing buttons, you’ll be able to select a partial flush for liquid waste and a full flush for solid waste.  In essence, the dual-flush technology allows you to save a lot of water because you’ll choose the flush mode as per the wastage.

  • Type of Bowl

There are numerous factors determining the kind of bowl to choose, including your desired comfort and size of your bathroom.  A toilet bowl can be rounded or elongated, each having its own benefits and limitations.

A round bowl takes the least space in the bathroom but provides minimal seating room. An elongated bowl, on the other hand, is more comfortable than its round counterpart but takes up more space in the bathroom.

I’ve noticed most people prefer rounded models, but a considerable number of homeowners are also leaning toward the elongated bowl shape. All in all, the choice of the bowl shape is entirely dependent on your needs.

The good news is that modern flushing toilets have been designed to be as compact as possible. That means, whether you opt for a round bowl or an elongated one, you’ll still be able to use just a small space in your bathroom.

  • Seat Height 

You need to consider the appropriate seat height when choosing a toilet. Flushing toilets come in different heights and it’d be useful to actually try out different models to gauge their comfort level.

The standard height for most toilet bowls ranges from 14 to 15 inches off the floor. For utmost comfort, I recommend opting for 17 to 19 inches but, of course, it all boils down to your comfort level and personal preference.

Some people prefer a lower toilet while others like a taller one. However, as my two cents, I encourage people to purchase a model that’s neither too high nor too low for your own height.

If too high, it might be challenging to sit down and stand up. And if too low, it might feel very uncomfortable to sit down for extended period and you might actually feel some pain in your lower back.

With a comfortable height, you won’t need to bend down and put pressure on some parts of your body.  Also, if you’re using a wheelchair or a related piece of equipment, I recommend opting for ADA-compliant models for they’re typically lower to the ground. You’ll find it easy to move from the wheelchair to a lower model.

  • Design & Color 

It’s vital to choose a toilet that blends with your bathroom décor, because this will accentuate your bathroom scheme.  A dull looking bathroom won’t be alluring.

Therefore, make sure to choose something that mixes and matches to make your bathroom as appealing to the eye. Pick a flush toilet that also matches the color of your bathroom.

I’ve noticed that 90% of buyers still opt for white, even though more and more colors are now available, such as green and blue. Going with white isn’t a crime, but just ensure it matches the color of your bathroom and makes it more appealing.

  • Noise Level 

A good flushing toilet is whisper quiet and lacks a noisy flush. Getting the best toilet with the quiet flush is even more important if your bathroom is located in proximity to the kitchen or living area.

A noiseless toilet won’t broadcast every flash, and is a great choice for small homes.  Another thing; make sure the toilet lid closing is also quiet.

Some toilet lids close so fast and end up making some irritating banging noise. I can tell you for a fact that such types of toilets can be precarious for young kids.


The little ones may accidentally have their slender fingers crashed against the bowl while closing the toilet lid. To avoid this mess, go with a quiet-close toilet lid that poses no danger to every user.

Final Verdict

Up to this point, I believe my best flushing toilet reviews have been an eye opener and you’re now in a position to select the best flushing toilet based on your needs.

You can choose the right model based on numerous factors, such as your toilet style or features like powerful flushing system, self-closing seat, and so much more.

Based on my years of experience in the plumbing industry, I strongly recommend the TOTO Drake CST744S-01 Toilet for all my friends. I’ve installed this one in my bathroom and it’s really giving my family and I the best toilet flushing experience. Try it too!
