What Is The Most Powerful Toilet?

Jump to Section

Finding the best flushing toilet can be a daunting task. There are so many options, and each of them has its own set of pros and cons. 

The problem with some toilets today is that they don't have enough power to get rid of all your waste in one flush. This is because most modern toilets use 1.6 gallons per flush (GPF) or less when it comes to flushing water down the drainpipe below ground level into a sewer system or septic tank. This means that you're wasting money every time you flush your toilet. Be sure to also check out our guide for Toto toilets vs. American Standard toilets vs. Kohler toilets to pick only the best and the most powerful toilet for your bathroom.

We've found some great examples that will save you money while giving you peace of mind knowing that all your waste will go down without clogging up pipes –  let's get right into the best picks when it comes to the most powerful flushing toilets.

The Toto CST744SF/R is a classic-style toilet, but this one comes with extra features to make it more attractive. It has an elongated bowl that allows you to sit comfortably and the 16.5″ height makes it perfect for people who need help getting on or off of their feet easily. This bathroom fixture also meets ADA guidelines so anyone can enjoy using this restroom item. 

One feature we love most about the seat cover is its powerful flushing capabilities; they're 125% stronger than regular 2” valves which mean everything will be cleaned away without any issues whatsoever. The 1.6 gallons per flush ensures nothing gets left behind when you push down on these buttons– your plumbing system becomes cleaner in just one flush.

This is another one of the Toto toilets and it is very similar to the one we have just looked at. However, this is a smaller, lower version that will appeal to anyone who prefers to be closer to the ground. It features the same G-Max powerful flushing system as its larger counterpart and uses 125% more water per flush than regular toilets – it's WaterSense certified.

This sleek, classic-style toilet from the well-known brand American Standard is designed with an advanced flushing system that ensures powerful and water-efficient cleaning.

The PowerWash rim features jets of pressurized air which force the bowl clean when you flush it; while siphoning sucks all contents away leaving a completely dry seat for your next visit to the restroom.


What to look for in a flushing toilet

1.GPM/gallons per flush (GPF) rating:

When shopping for new toilets, it's important to know which is the main number to look for – this is known as gallons-per-flush or GPF. You may have noticed that measuring cups in the kitchen are marked with a certain capacity, but aren't labeled with ‘gallons per minute' or ‘liters per second.'

This is because 1 gallon equals about 3.7 liters and so these units cancel each other out when you're working out how much water will be used in an average flush. So, if your home has 1″ pipes and you want a toilet that uses just 1 gallon of water per flush, then this means every time you push down on the flushing lever, the toilet will release 3.7 liters of water. 

2. Gravity-fed or pressure-assisted flush

Pressure-assisted toilets are those which use some kind of tank to store pressurized water, usually air that is forced into a holding tank by an electric pump or a gas mechanism below ground level. 

This happens before it is released through a hose and ejected out into the drainpipe at very high speeds in order to push everything in front of it down and away from the opening at the bottom of your toilet bowl.

Gravity-fed toilets on the other hand don't rely on any sort of external pressurized water source for power; rather, they ‘push' waste through your pipes to sewer destinations using only gravity as a main source of power.

3. Flushing mechanism

The flushing mechanism in a flush toilet is the part that you need to pay attention to. It's important that your new toilet has quality construction and is made of durable, high-quality materials, or else it'll break down on you sooner than later. Toilets can be a real pain to deal with when they start to break down, and if you're not careful about how much water pressure is used with every flush, then your bathroom pipes are going to cause more trouble than the toilet itself.

When choosing a new toilet look for one that has an ‘A' or ‘A+' rating on its flushing mechanism. These ratings mean that there has been scheduled testing on these toilets so they've proven themselves in the category of reliability and durability. 

4. Type of water pipes

Another thing to consider when shopping around for new toilets is what type of plumbing connections your home already has set up; this will make finding replacements even easier because you can just look for those same types again. The most common types are ‘P' shanks and ‘T' bolts.

If you have P-shank type connections installed throughout your house then chances are good that either an elongated bowl or round bowl will work well for you, but if T-bolt type connections are installed, then you'll want models that have the T-shaped bolt holes for more compatibility and ease of re-installing.

What toilet is best for not clogging?

Now and then you might find yourself with a clogged toilet, no matter how hard you try. From time to time, even the best toilets will clog up because they were not installed properly or there is just too much waste being flushed down them regularly. 

It is important to know that not all toilets are as good as others when it comes to avoiding clogs; though luckily for you, knowing what makes a toilet clog-proof can go a long way towards helping you avoid problems in the future.

Further considerations when it comes to choosing the right flushing toilet

Size of pipe

One of the most common reasons why a toilet tends to get blocked up is because its pipe size is too small for it; which means that the amount of pressure pushing waste through pipes gets restricted before it even gets to the toilet itself. When this happens, clogs are created and you can bet that your toilet will be backed up as a result.

Special flushing systems

Certain toilets have special flush mechanisms or nozzles installed in them which allow for more efficient flushing through larger amounts of water. Because these types of toilets use stronger pressure than other models to get rid of waste, they also produce much more force pushing collected waste down towards the pipes below.

This combination is very effective for ensuring a good flush every time. Just be careful not to block up your bathroom pipes by using too strong of a force when flushing your toilet. 


Finally, there's one last thing you should know about choosing the best toilet to avoid clogs, and that's the material from which it is constructed. Some of the most clog-resistant toilets on the market today are made from durable ceramic and plastic, but there are also some good models made from porcelain or even steel.

The Oval vs. Round bowl debate

Some people believe that round toilets are better, while others argue that the oval variety is truly superior. Of course, there's no right answer in this regard; it all depends on your preferences and needs (and the bathroom design of your home). 

If you have an older house or a traditional style, then round bowls will probably work more effectively for you. But if you like something more modern in appearance with more chrome accents, then it might be worth considering an oval toilet bowl instead.

Size of the toilet

The size of your toilet depends on where you plan to install it. This is especially important if you are remodeling a space and want to match the existing plumbing fixtures in your home. Aside from that, there are two main considerations when choosing the right size for your bathroom: one is comfort and another one is appearance.

Environmental impact

If environmental conservation is important to you, then one last thing to keep in mind when choosing a new toilet is what kind of effect it has on our environment. This includes both how much water is used by each model as well as whether or not it is made from sustainable, recycled, or biodegradable materials.

How do I make my toilet flush more powerful?

There are many ways you can make your toilet flush more powerfully, and some of them are mentioned below.

Changing the flapper

If you're one of those people who doesn't exactly like the noise that your toilet's flapper makes each time it seals shut, then we suggest changing it for a newer, quieter version. 

This is usually a straightforward procedure; just dump out all of the water from inside the tank (first), remove the old flapper by getting rid of its mounting screws, put the new flapper in place with fresh gaskets, and sealant tape, and then refill your bowl to finish off.

Water pressure adjustment on the tank

Another trick to putting extra pressure behind your bathroom fixtures is by using a pressure regulator attachment on top of the tank. 

This part of your toilet is responsible for storing your water, so if you're experiencing problems with low pressure it could be a good idea to try adjusting that setting up to see if it solves any issues you have when flushing waste away. 

O-ring replacement

It's also possible that the O-rings inside your toilet or its tank are worn out or damaged; this can create lower than usual water pressure and therefore a less forceful flush. If you think replacing these rings will help, then just unscrew them and put in new ones from home depot or a similar hardware store.

Adjusting float level

The float ball controls how much water leaves the tank each time you flush, so reducing its level will increase the flush's force. To do this, make use of a flat head screwdriver to adjust it until you get the desired effect.

Using a toilet tank auger

An alternative method you can use to clear your toilet's blockage is by using a toilet tank auger. This hand-held plumbing device has an extended cable on it with a removable tip, which helps it bust through any clogs that are in the way and clear your bowl. 

The bad news is though, not all of these items are created equally; some of them are more effective than others when they come to unclogging wet traps or other tough spots.

Shop for new parts or replacement components:

If none of those methods worked then perhaps you need to change out some broken parts instead. For example, if you want to buy a new flapper for your toilet then look for that specific part name along with “replacement” and it should show some results that will help.

Final thoughts on the most powerful toilets

Regardless of or not you make changes to your existing plumbing system or invest in replacement parts, there's no denying that it is possible to increase the force behind a toilet's flush. 

In any case, your goal should be to improve how well your bathroom fixtures work without making too many changes; as long as nothing is broken or damaged on these fixtures already, then it's good to know that you're fully capable of making minor adjustments.
