Buying Guide for the Best Toilet for Flushing Large Waste

A flush toilet is an essential part of a home. It can become a severe source of embarrassment and frustration, especially if you have guests around your home. Unfortunately, a great majority of standard toilets can’t move large waste.

Another common problem with this type of toilet is noise and discomfort. Most people associate powerfully flushing toilets with lots of noise. This may be factual in most cases, but not all brands are currently in the market.

So what makes up the best toilet for flushing large waste, and how can you arrive at that decision? We will answer or attempt to solve these and many more questions in this section. So, here are the most important factors worth considering when shopping for the most vigorous flushing toilet.

Toilet Design (Single-Piece Or Two-Piece)

Flush toilets come in either of two designs – one-piece and two-piece. Traditionally, toilets consisted of a tank and a bowl as separate entities. The two parts are connected via a pipe. Such design is what we term two-piece.

Single piece models, as the name sounds, the two parts are lumped together in one thing. Modern models have gone the single-piece way. The question is whether there is a difference between the two models.

While the two differ considerably in appearance, the difference is mainly cosmetic. In terms of performance, the two are at par, according to many people. The significant advantage of single-piece models is their compact design, making installation easy, especially where bathroom space is limited.

The availability of those two design models is excellent because you have the chance to pick the one that is cosmetically appealing to you and meets your expectations.

Flushing Power

This article aims to expound and introduce you to the best toilet for flushing large waste. Well, the ability of a bathroom to wash away vast chunks of human waste depends squarely on the flushing power of such a toilet.

Famous brands are trying to outdo each other in engineering robust flushing systems. Siphon jet is perhaps the most famous and is so far successful. However, many brands are coming up with unique and robust systems that promise to revolutionize the flushing mechanism of contemporary flush toilets.

The primary system includes gravity, pressure-assisted, dual and single flush systems, double cyclone systems, tornado flush systems, double vortex, and tower style. Each of these new mechanisms aims to outperform the earlier versions and succeed.

We would recommend that you try these new flushing mechanisms if the previous one your toilet is using is not working efficiently. If you do not understand what these technologies mean, then you can speak to an experienced plumber to help you make an informed decision.

Water Efficiency

I bet you agree that utility bills can be choking. But, unfortunately, things are even harder right because of the global pandemic. So you should take the earliest opportunity to save on your water bills by installing the most efficient flush toilet.

Toilets are rated in terms of gallons per flush or GPF. Generally, a lower rating would mean the tank is water efficient and will save you some money over time. According to WaterSense and Environmental Protection Agency (EPA), toilets should have a flush rate of 2 gallons per flush or even less.

You will see most brands rated 1.28 GPF or 1.6 GPF. These are well within with EPA criteria for water conservation. In addition, some models feature dual flush technology, which allows you to use lesser water to flush smaller waist and vice versa.

Flush Valve and Trap-way

Although it’s not given much attention, flush valve and trap-way play a vital role in determining the performance of a flush toilet. The wider the valve, the more water it will flow through and hence a more powerful flush.

Standard toilets have valves measuring 2 inches in diameter. Anything larger than that generally generates a faster and more powerful flush. You can easily find the information about valve measurement in the description of the toilet that interests you. Therefore, you need to pay close attention so that promoters do not dupe you.

Comfort And User Friendliness

You will notice that many brands are talking about right height or chair height toilets. How high a bathroom is determined how comfortable and ergonomic the toilet will be. The height should be 17 inches which is the same height as chairs.

Such measurements make it easy to sit down and wake up from the toilet. You will also feel comfortable as short toilets will flex your legs and make you feel tense. Furthermore, people living with physical limitations can easily use right-height.

However, if you are short, very high toilets may feel uncomfortable. Therefore, you need to choose a toilet height that you find comfortable. Taller than average individuals may benefit from toilets taller than 17 inches.

Round Vs. Elongated Bowl

In terms of design, toilets for flushing prominent waste feature either round or elongated bowls. According to many homeowners, elongated bowls are more comfortable than round models. This is because they offer a larger seating surface.

This does not mean round bowl models are uncomfortable. People have different tastes and preferences. Therefore, we leave the decision to you. The truth, however, is that taller toilets with long bowls are a lot more comfortable and ergonomic to use, even by the elderly.

It is also worthwhile and rewarding to point out that round bowled toilets require lesser space for installation. Therefore, they are ideal for smaller bathrooms. The bottom line is you choose wisely.


The most potent flushing toilet is not a cheap investment. It is, therefore, vital for you to know all the costs involved before you decide which brand to go for. Generally, famous brands are more expensive but are trustworthy.

Currently, the price of flush toilets ranges from a few hundred dollars to thousands. Being very expensive does not mean quality and vice versa. You can do some balancing and juggling to find a high-quality but affordable model. It is also worthwhile to have it at the back of your mind that you will pay about $80 to have a plumber install the toilet in your bathroom.


What is the best flushing technology for powerful toilets?

Newer flushing technologies such as double vortex, tornado, or cyclone systems do fantastic jobs. Famous models are now embracing the latest technology.

What is the difference between gravity and siphon jet flush?

Siphon jets tend to use twice as much water as gravity models. Therefore, the larger is more efficient in conserving water than the former. However, a siphon jet flush effectively forces away waste than a gravity flush.

What is the largest trap-way a toilet can have?

Trap-way and valve play a vital role in the performance of a toilet. The larger the trap-way, the more water it will allow to pass and faster speed guaranteeing effective flushing of significant waste. The largest trap-way and valve currently measures 2-3/8 inches diameter and 4 inches in diameter, respectively.

Can I stall a flush toilet on my own?

It is almost impossible for you to install a flush toilet on your own, even if you have the expertise. It’s a bulky and heavy bathroom fixture. Trying to handle it alone can only predispose it to damage. So, it would make a lot of sense to seek a plumber’s service.
