Powerful Flushing Toilets (Strong Flush) 10 Reviews – Toiletable

The American Standard Champion 4 is a mighty waste-eating beast, featuring an accelerator flush valve of 4 inches, the largest of all toilets!

It’s a gravity flush-type toilet with a siphon-action bowl that jets waste through the spacious waterway at a cyclonic speed, ensuring a clean, powerful flush.

The fully glazed siphon trapway measures 2 3/8 inches, which is also the largest in its class. It claims to remove 70% more solid waste than any other toilet on the same level.

Its special EverClean glaze coating on the toilet surface blocks the growth of sticky stains and odor-causing bacteria, protecting the toilet’s vitreous china material. This glaze, along with the one-piece style, makes this toilet one of the most durable and reliable out there.

Although it is not EPA-compliant, the American Standard Champion 4 still saves water compared to standard toilets. At 1.6 gallons per flush, you’ll be amazed at how powerful each flush is while staying water-wise.

The Champion 4 is available in 3 different colors and two different heights; comfort and normal height. People of every age, height and body weight will be comfortable on the ADA-height compliant height, which makes sitting down and standing up easier. The elongated seat provides added comfort. A sleek one-piece design makes for easy cleaning and installation, which comes alongside a slow-close, slam-proof toilet seat.

With a high customer rating, Amazon reviewers rave about the Champion 4’s flushing system and high-quality material!

Taking all of this into account, we’ve concluded that the Champion 4, with its virtually clog-free flushing system, is our favorite flush on the market! So please read our in-depth review of this toilet here and see if you agree with us.

Facts Outside of Manual

We checked out some of the more relevant and frequently asked questions about the Champion 4, and here’s what we found; 

❓ Customers wondered if the toilet came with a complete kit, and although the toilet comes with a seat included, the wax ring and supply line will need to be purchased separately.

❓ When it comes to cleaning, avoid harsh detergents and bleaches, instead opting for softer toilet cleaners, using a soft-bristled brush.

❓ The tank can be manually filled for homes off-grid or in a situation where the water line is off.

Review Highlights 

👉  The Champion 4 leaves a lot of customers very satisfied. In fact, one customer loves their Champion 4 so much, they gave it the nickname “The Beast”.

👉  This is a common sentiment. Customers commented on the stylishness and reliability of this model, even in households with admittedly “busy-bowels”.

👉  The powerful flush and EverClean coating lend themselves to minimal bowl cleaning. Customers mentioned the comfort of the Champion 4, both height and seat-wise.

Kohler is well-known all over the world for its high-quality products. Among the most popular options is the Kohler K-3999 Highline flushing toilet, both effective and powerful.

The Highline is made of high-quality china, making it durable and crack resistant. As it is a floor-mounted flushing toilet, the installation process is simple with users rarely facing any difficulties.

The Kohler Highline’s reasonable price did not come at the expense of its performance, and we love this toilet for its powerful flushing system and affordable cost.

The Class Five flushing technology allows for a virtually clog-free flush, making the Kohler Highline one of the top flushing toilets on the market. The flushing system uses the force of gravity and a precision-engineered design to create a strong siphon during flushing, which we found prevents both clogging and streak marks on the bowl. 

It may not be the most water-efficient option, but it still falls within EPA guidelines and saves gallons more than a normal toilet. In fact, the Highline consumes only 1.28 gallons per flush, compared to a normal 3.5 gallons per flush toilet. That’s up to 16,000 gallons of water saved every year!

Still, we noticed that the Highline does tend to be a little noisy.

The Kohler Highline is a two-piece flushing toilet, making it slightly more difficult to clean, but still much lighter than a one-piece toilet. We found that its lighter weight makes installation easier, especially if you have trouble lifting heavy items. In addition, its three-bolt quick-connect technology also simplifies the installation process.

Due to the comfort height seat, it is a good choice for the elderly and people with movement disabilities. The elongated bowl also adds room and comfort.

The Highline is available in two colors, biscuit or black, and three different finishes, with the option for a round or elongated bowl.

Unfortunately, the seat and supply line are sold separately.

Facts Outside of Manual

Customers helped one another and answered each other’s important questions. Here’s what we found:

❓ The flush is short, only about 4 seconds long, and fill-up is quick and quiet.

❓ You won’t need to worry about a weight limit. One customer commented that his Highline had no problems with a house member weighing over 300 pounds.

❓ The Highline fits comfortably in small spaces, like inside a mobile home.

Review Highlights 

👉  Customers loved the comfort and accessibility of this toilet. One customer praised the “comfortable landing” which suited his wife’s needs perfectly after her hip surgery.

👉  Customers raved about the Kohler Highline’s easy installation. One woman put it together in no time, and we agree with her when she says it was quite a feat – after all, she is only 5”4! 

👉  The Highline’s easy and minimal cleaning requirements make this toilet even more popular. One review let us know that any plunger will fit the Highline despite its unique design. In all his time of owning this toilet, he’s only had to clear a clog once – unlike the troublesome toilet it replaced. He’s right when he says “the difference is in the hardware.”

American Standard siphonic dual flush models are some of the best flushing toilets on the market when it comes to engaging the most impactful flushing technology in modern bathrooms. The two-piece style makes this a versatile toilet, with a sleek design that would fit both contemporary or classically furnished bathrooms.

The H2Option’s PowerWash rim and siphon jet bowl technology provide optimal flushing performance while still saving a substantial amount of water.

It is both EPA WaterSense certified and meets MaP premium criteria thanks to its water efficiency. The H2Option’s name speaks for itself – this really is one of the most water-conscious toilets out there.

In this dual-flush American Standard model, the primary flushing (or full flush) rate is 1.28 GPF, whereas the secondary flushing (or half flushing) capacity is 0.92 GPF.

While the weaker flush option can steadily eliminate liquid waste with a single flush, we found that the full flush mode will wipe off stains from even the most obscure curves of the bowl. The ability to choose your water usage per flush will undoubtedly save money on your water bill without sacrificing cleanliness. 

The American Standard H2Option is equipped with an EverClean surface, which prevents the growth of bacteria, mold, and mildew on the surface. In addition, the toilet’s powerful flushing system ensures a clear flush, which we found reduces how often the toilet needs to be cleaned. The 2 inch trapway helps effectively clear the bowl with every flush and prevent clogging.

The H2Option comes in three different finishes and has a limited 5-year warranty on all mechanical parts. There is an option for a round bowl or an elongated bowl, as well as two different options for the height of the toilet. We found installation to be relatively easy and loved the classic white color of the toilet. Unfortunately, the seat is sold separately. 

The H2Option comes in two different models. The model above is not ADA-compliant, but the other one is. Both of the models have a dual flush option and are available in three different finishes. Additionally, both are highly efficient, consuming only 1.28 gallons of water per flush.

Facts Outside of Manual

We put together the most common and useful customer-asked questions about the H2Option. Here are the answers we found:

❓ American Standard will help you directly should you need any replacement parts. 

❓ American Standard don’t offer a specific matching toilet seat for the H2Option, but any standard elongated seat will work.

❓ The stiff dual-flush buttons may make it difficult for a small child to push down.

Review Highlights 

👉   One customer summed up the H2Option beautifully – “save water, save space, and feel happy white you do it.” He was especially happy about no longer needing to double flush given his diet of brick-like foods. 

👉   The H2Option’s flushing power has impressed dozens of customers. One review said that the toilet can “deal with six double bacon-chilli-cheeseburgers” and still leave the bowl sparkling afterwards.

👉  Customers of all ages, including the elderly, love this toilet. A customer remarked that he has been loyal to American Standard for years and as he and his wife get older, American Standard only continues to meet their needs.

The Kohler Wellworth toilet is a powerful flushing toilet with Class Five flushing technology that offers a comfortable, but modern design. Kohler toilets are known to be high-calibre, and the Wellworth Classic is no exception.

The Wellworth Classic’s flushing system impressed us with its power and efficiency. It uses a precision-engineered tank and the force of gravity to flush. It has a wide trapway and creates a strong siphon during flushing action to prevent clogging, and a canister flush valve further optimizes flushing performance.

The Wellworth Classic consumes only 1.28 GPF and is considered a low-consumption toilet. Compared to normal toilets, this level of water consumption saves you approximately 16,000 gallons a year!

The Wellworth has a classic two-piece design with an elongated bowl for added comfort. It is made out of durable china and is available in four finishes, with the seat and supply line sold separately. This model is unfortunately not ADA compliant, however, and would be better suited in homes without those needs.

The Wellworth Classic is also quite easy to install due to the standard 12-inch rough-in. Additionally, it features the DryLock install system, which we found to be foolproof and fast, preventing any leakages that could occur during the installation process. It coordinates with other products in Kohler’s Wellworth collection for a streamlined bathroom design.

Facts Outside of Manual

Here we have the most useful and common questions about the Wellworth:

❓ The Wellworth comes without a wax ring and lid.

❓ The tank is insulated.

Review Highlights 

👉   Wellworths must be contagious – as soon as you put one in one bathroom, they start appearing in the others. At least that’s what happened to one reviewer, who ended up loving his first toilet so much, he got 3! We guess he just couldn’t get enough of this “amazingly quiet, super quick-flushing” model.

👉   We can’t forget about another Wellworth highlight – the reliability. Customers remark that the toilet is “very efficient” when it comes to flushing and cleaning.

👉   The look of this toilet had customers very satisfied. “Classy and simple, but in an elegant way,” the Wellworth compliments any bathroom.

The next toilet on our list is a WaterSense certified and ADA-compliant model from TOTO, the Ultramax ll. The Ultramax II was a close runner-up in our list, with plenty of attractive flushing and design features.

The ceramic toilet bowl, coated with TOTO’s own Cefiontect, inhibits the build-up of bacteria and microbes that cause odor. As a result, you get a fresh-smelling, hygienic, crystal-clean toilet after each flush.

The exclusive Cefiontect glaze prevents dirt and dust from sticking to the ceramic surface, which we found made it much easier to clean compared to other toilets. 

Despite using only 1.28 gallons of water per flush, the Ultramax ll has one of the best flushing systems on the market. The Tornado Flush flushing system fills the bowl quickly and empties it forcefully, effectively removing all streaks and waste from the bowl.

We found that the toilet refills quickly and quietly within a matter of seconds, and with a large 2 1/8 inch, computer-designed trapway, clogging is something you’re rarely like to face.

We love the TOTO Ultramax ll’s streamlined, modern look. It is a one-piece toilet with an elongated bowl, and is available in a number of different colors, including several white tones, beige, and ebony. With the option for a right or left hand trip lever, this toilet can be completely customized to suit your bathroom. 

The trip lever comes in ten different finishes (note: there is an up-charge for some of the finishes). The Ultramax ll has a slow-close seat, which prevents slamming, and the Universal Height feature allows people of all ages to enjoy a comfortable toilet experience.

Having reviewed many toilets, we found this one to be easier than most to install, requiring just a few necessary parts.

Facts Outside of Manual

We found answers to some of the most common and useful questions about TOTO’s Ultramax II:

❓ Any TOTO washlet or bidet will be compatible with the Ultramax II.

❓ The brightest, most purest white colour available is Cotton White

❓ There is no way to change the bowl’s water level, but you can adjust the water level in the tank if necessary.

Review Highlights 

👉   Customers consider the Ultramax II to be “the closest you can get to a pressure assisted toilet,” like in an aeroplane, minus the noise and installation issues. 

👉   The Ultramax II boasts an “excellent design and flushing system.” Customers who have had this toilet for months have not experienced a single clog!

👉   It seems like there can’t be enough said for the quiet flush and low water consumption coupled with considerable power. Rest assured, 1.2 gallons will be more than enough to deal with those “ample bowlfuls.”

A popular and thoroughly reviewed toilet, the TOTO Drake ll is an impressive toilet with a beautiful design and powerful flushing system. The amount of reviews allow us to get a solid sense of user happiness, and the Drake II doesn’t disappoint. It is an EPA WaterSense certified and ADA compliant toilet, suitable for a variety of height and comfort needs.

The TOTO Drake II’s double cyclone flushing system is the lifeline of this wonderful, highly water-efficient model. The two nozzles jet down the water in the toilet bowl at exhilarating speed for flawless flushing action, especially around the rim and bowl wall.

Some reviewers did note that the flush tends to be louder than other toilets, but felt that the power makes up for that.

The fully-glazed trapway is computer designed to prevent clogs, which the TOTO Drake ll proved to be excellent at doing in our flushing tests. 

Special credit goes to the 1.28 gallons per flush maximum flushing rate! This low consumption level helps save water, benefiting the environment and reducing your water bill.

In addition, we found that this toilet helps you save time cleaning and maintaining it thanks to the SanaGloss coating on the bowl. This gloss coating prevents stain build-up and the growth of bacteria and fungi, ensuring that your toilet stays clean and sparkling. The powerful flushing action around the toilet’s rim and bowl wall keeps it clean longer than toilets with less powerful flushing systems.

Of all of the many toilets we’ve reviewed, this one offers the most options when it comes to color, coming in five different finishes!

In addition, there is an option for a right hand or left hand trip lever, which comes in nine different finishes (note: there is an up-charge for some of the finishes).

The elongated bowl adds comfort and the universal height features makes sure that people of all ages will find it easy to use.

The wax ring, seat, and supply have to be purchased separately, but otherwise, installation is easy.

Facts Outside of Manual

Of the questions asked, we found the most useful out-of-manual information about the Drake II:

❓ The correct cleaning approach is to use a mild dish detergent and a soft plastic brush. Avoid cleaner, polishing powder or detergents with a gritty texture, and hard metal brushes, which will damage the seal .

❓ You can get color swatches from TOTO to ensure your toilet is the perfect fit for your bathroom. This is the case with most TOTO toilets, not just the Drake II.

Review Highlights 

👉  The Drake II saw some shining reviews. TOTO is known for their quality and the Drake II continues that reputation, transforming customers into lifelong TOTO buyers. It seems the toilet is so life changing, “every time someone ensconces themselves upon it’s cool seat of perfection, the angels sing. The stars shine brighter. Your troubles melt away to nothingness. Your life has meaning.” If that isn’t a happy customer, we don’t know what is!

👉   The Drake II’s reliability is a marvel to this customer, who made sure to put it to the test when it came to clogs. His toilet has seen “over 500 flushes without any misses!” The low 1.28GPF means that every one of these flushes save water and money.

👉   Installing the Drake II is a breeze! One woman in her fifties said that, with just a little home repair knowledge, it took her just half an hour to install the easily carryable two-piece toilet.

A toilet designed for cleanliness, the TOTO Promenade ll features TOTO's renowned, ultra-powerful Tornado Flush flushing system and is both EPA-certified and ADA-compliant.

With this toilet, you certainly won’t have any cleaning or maintenance problems. One of our favorite TOTO features, the Cefiontect ceramic glaze, prevents debris and waste from sticking to the toilet bowl and ceramic parts of the toilet. You won’t need to waste time with frequent cleans when it comes to the Promenade II.

To reduce the frequency of cleanings even more, the toilet uses the Tornado Flush flushing system. With this streamlined and systematic flushing system, you won’t have to waste water flushing multiple times to remove waste from the bowl and likely needing to clean afterwards.

This model is quite water efficient, consuming only 1.28 gallons per flush, potentially saving you hundreds or even thousands of dollars each year in water bills! 

The Promenade II comes in four different color options - cotton and colonial white, sedona beige, and bone - complementing all bathroom types.

The trip lever comes in four different finishes, and there is an option for a right or left hand trip lever (note: some finishes have an up-charge). The Promenade II is slightly heavier than other toilets in its class and weighs about 91.5 pounds.

If you can lift it, installation should be easy, as it is a two-piece toilet.

Facts Outside of Manual

The more frequent and important questions asked by customers were answered by both the manufacturer and other customer’s experience:

❓ The Promenade II comes with a washlet channel, which you will need an outlet for if you choose to set it up. This channel only fits regular washlets.

❓ The noise level of this toilet is what you would expect from any high-performance model. The flush is not obnoxiously loud, but the flush is louder than a normal toilet. Environmental factors like the size of the room or the toilet’s proximity to the door will influence the volume level.

Review Highlights 

👉   One customer called this the upgraded Drake II, saying he “shelled out the extra few bucks because I wanted a more ornate toilet,” and couldn’t be happier with his choice. 

👉 Customers love how easy this toilet is to clean, giving credit to the improved CeFiONtect glaze. This low-maintenance is a huge timesaver for users, who can now “flush once and move on (after washing your hands of course)” as one customer described. The bowl design also makes cleaning a breeze, with a larger base than standard toilets to help avoid the “splatter” caused by standing men.

👉  The Promenade II’s performance is the most talked about review topic. The rotational flush cleans every inch of the bowl,  and ensures that every bit of waste goes down the drain. One customer said its as easy as pulling the lever towards you and… “woooosh! It’s all gone!” Simple as that.

The American Standard Baby Devoro is a powerful toilet with an excellent flushing system. Since it has a 10.25-inch seat, kids and smaller adults will be able to easily access this flushing toilet. This makes it a great choice for healthcare or daycare facilities for kids. 

Let’s not overlook how powerful and efficient this toilet is. Size is the only thing about it that’s small - the flushing power is massive. It offers a clean and strong flush, consuming only 1.28 GPF and meeting EPA WaterSense criteria. The strong siphon flushing action ensures a clean bowl after each flush. The Baby Devoro has a 2-1/8-inch glazed trapway, which we found prevents clogs. The MaP score is 500 grams at 1.28 GPF, not the highest score possible, but still excellent! 

Since it has a round-shape, this might not be the most comfortable model, but, taking into account that it is a toilet meant for kids, this shouldn’t be much of a problem. When it comes to durability, the Baby Devoro FloWise does a great job. It is made of long-lasting high-quality china that we found to be easy to clean.

The Baby Devoro two-piece toilet comes in one color, white, and also includes two bolt caps that match the color of the toilet. The seat is unfortunately not included, but installation shouldn’t be too difficult, especially considering the smaller size and lower weight.

Facts Outside of Manual

These are two of the most frequently asked and useful questions about the Baby Devoro:

❓ The Baby Devoro fits all standard sewage pipes, and can be installed in the place of any standard toilet. However, be sure that your rough-in is 10 inches for a perfect fit, or your new toilet won’t connect to your water system.

❓ The Baby Devoro comes without the seat. One can be bought through American Standard, or you can find a suitably sized seat elsewhere - multiple reviewers suggest the Bemis seat, a great choice when it comes to children and potty training.

Review Highlights 

👉   The Baby Devoro is designed to suit the diverse needs of children, and many customers were relieved to find the proper solution for their potty problems. One user was struggling to potty train her three year old, but the Baby Devoro made it easier than she could have imagined! “There are only a few parents out there who would be willing to go this far,” she says, “but it is well worth it if you do!” 

👉   This toilet is lightweight and easy to install, and fits your standard sewer pipe, like a regular sized toilet, so there’s no need to do any resizing at your drain. One preschool teacher reviewed that she was easily able to carry and install more than one Baby Devoro in no time at all!

👉   Hang on though, this toilet isn’t just for kids! One customer installed this toilet in his cozy RV, and it fit perfectly. The Baby Devoro is compact and sturdy, with a flush that works for children and adults. Using the Baby Devoro can even boost your digestive health! The short height puts the user in a “natural squatting position that is more efficient and healthy for using a toilet,” according to both this RV-driving reviewer and health care professionals.

With its unique design, the Eco Soiree definitely stands out from the crowd. This strong flushing toilet is durable and efficient, meeting both EPA WaterSense criteria and ADA regulations.

This toilet features one of our favorite TOTO technologies: the Cefiontect ceramic glaze. This glaze keeps the ceramic pieces of the toilet free from dust and dirt, reducing how often you will need to clean it and protecting your toilet.

Additionally, the TOTO Eco Soiree comes with TOTO's renowned powerful Tornado flushing system, which uses gravity and centrifugal force to eliminate all waste from the bowl quickly and without clogs. We were impressed by how well it kept the bowl clean, further reducing how often it needed cleaning!

The TOTO Eco Soiree is made of ceramic and weighs about 90 pounds. Since it is made of such a high-quality material, it is quite durable. It is a one-piece toilet with an elongated bowl, and its ergonomic, universal height design provides you maximum comfort.

The Eco Soiree also comes along with a soft-close seat made out of high-impact plastic. Characteristic of TOTO, the Eco Soiree comes in five colours

It has a classic 12-inch rough-in and is very simple to install.

Facts Outside of Manual

These are the answers to some of the most interesting and common questions asked by customers:

❓ The Eco Soiree is compatible with most toilevators, provided the toilevator is designed for a standard toilet size.

❓ TOTO offers the standard 12 inch rough-in size, but the Eco Soiree can also be adapted for A 10 inch rough-in, allowing for a cozier fit in smaller spaces.

Review Highlights 

👉   The power of this flush has customers blown away. Clogs are a problem of the past, as the Eco Soiree seems to cleanly suck the contents of the bowl down the drain. One customer trusts his toilet’s flush so much, he said “you could probably flush a beach towel down it if you wanted to, not that I would recommend it!” Maybe beach towels are a stretch, but the Eco Soiree is guaranteed to handle all the natural waste you’ve got.

👉 The attractiveness of this toilet has customers beaming with pride. Customers “are confident that whenever guests come over and need to use the bathroom that they will have a pleasant experience.” This stylish appearance is made even better by the Eco Soiree’s low maintenance cleaning needs. The powerful flush, sleek clean lines and protective Sanagloss will ensure your toilet is always presentable for any guest.

👉  Installing the Eco Soiree can be tricky because it’s a heavy one-piece toilet, but this depends on who’s installing it - one 68-year-old customer said he installed 2 toilets himself. The same man is very happy with his purchase, even if this model is a tad pricey. But, in his words, “you get what you pay for and these 2 are going to be around long after I die.”
