To make the best decision, it’s important to understand what makes a one-piece toilet unique. Your ability to make a well-informed purchase selection will be greatly aided by your familiarity with the fundamentals of this plumbing item. Let us now guide you in finding the best one-piece toilets:

best 1 piece toilet

√ Toilet Height

When it comes to using the restroom daily, some individuals spend a large amount of time there while others hardly spend any time at all doing so.

Nobody enjoys being uneasy no matter how long they spend in a restroom. The seat and the height of the toilet are the two most important features of a pleasant toilet.

A toilet seat may be swapped out in a matter of seconds, but the height of the bowl remains fixed. The height of a one-piece toilet is determined by the distance from the floor to the top of the bowl when the toilet seat is removed.

√ Materials

Because it affects things like the toilet’s longevity and how it looks, the material you pick for your one-piece toilet is crucial. Porcelain, vitreous china, and ceramics are the most common materials used to create one-piece toilets due to their famed durability. One-piece toilets are very long-lasting because to the sturdy material and the skirted design that prevents them from leaking. In addition, they are aesthetically pleasing and sophisticated due to their glossy finishes. The one catch is that they tend to be pricey, so you may need to spend more money than you had planned. Plastic units are often used due to their low cost and portability.

√ Size

Although it seems apparent, when faced with so many potential aesthetic outcomes, this detail is often overlooked. Several physical factors should be taken into account to ensure that the toilet you choose fits comfortably in your bathroom.

Will a high toilet seat be necessary? How important is it that the toilet fit through a tight doorway? To what degree of separation from the wall do you like your toilet to be placed? This is the ‘rough-in’ measurement. In general, toilets come in a variety of sizes, so you’ll want to check the measurements of your bathroom before making a purchase.

Rough-in heights are typically between 10 and 14 inches. The ideal height for an adult toilet bowl is between 14 and 18 inches; a child’s toilet bowl should be between 10 and 14 inches from the floor.

√ Shape

Both circular and elongated toilets exist. What you choose will be determined by how much room you have in your bathroom and what kind of style you want to go for. It has been found that many people find the extended toilet bowl to be more accommodating. However, if you’re short on room, a circular toilet is your best choice.

√ Method of Flushing

The market is stocked with a wide variety of flushing commodes to suit your needs. You may not be able to utilize some bogs. That’s why it hurts to try different flushes before you discover the proper one. A soft light should be able to wash away grime. Primarily, it implies that a well-functioning toilet has a decent flush. However, the G-Max, Double Cyclone, and Dual Flushing Symphonic Flush are, to the best of my knowledge, excellent options. Check the toilet’s flushing capability before you purchase it. A dual-flush toilet is the best option, since it solves both problems at once.

√ Comfort

You need to make sure that your bathroom’s toilet seat is just right. Because it will take a long time to get used to it. There are requirements for the assistance features such as a large range of height and size adjustments, a forceful flush, and a simple design that makes it easy to install and clean. The attractive appearance is as much a part of the comfort function as the seat materials. The cumulative effects provide your utmost ease.

√ Eco-Friendliness

With each flush, about how much water does the toilet consume? Why shouldn’t your toilet be the most cost-effective and environmentally friendly choice on the market, given that we’re all a bit more conscientious about preventing unnecessary water and energy use these days?  Almost all modern toilets are made in this way without compromising flush power. Choose a toilet that uses no more than 1.28 gallons of water per flush (GPF). Selecting a toilet that allows for both partial and complete flushes might also be useful.

√ Water consumption

Water use for waste removal in flush toilets is typically high. It seems to reason that if you have to pay more for water, you will also have to pay more for energy. Furthermore, there are opportunities for substantial annual water waste. That’s why it’s important to choose a waterless, energy-efficient toilet that won’t hurt the planet. One-piece toilets that use two to three gallons of water every flush are what you should have.

√ Budget

A tight spending plan is essential when purchasing anything, not just bathrooms. It’s a common misconception that a bigger budget automatically results in a better end result. There are several high-quality one-piece toilets available at a reasonable price, at least in my experience. Don’t fret if money is scarce! It’s not easy to find fitting accessories for your bathroom. Keep in mind that if you want the highest quality and features, you’ll have to pay a premium. The greatest items may often be found at reasonable prices if you take the time to do some research before making a purchase.

√ Ease of cleaning

Knowing how frequently and how challenging it will be to clean the toilet is crucial information to have at the outset. Unsanitary toilets are a breeding ground for germs. The simple design and single component construction of one-piece toilets make maintenance a breeze. These commodes are made without any hidden crevices where mold may hide and spread unchecked.


In this first segment, we review seven of the best one piece toilets on the market as of now:



This Toto Eco Soiree toilet is the one to choose if you want a toilet that will go in with your modern, minimalist bathroom design. The streamlined form and low-profile silhouette of the TOTO MS964214CEFG#01 Eco Soiree Elongated One Piece Toilet are both visually beautiful, yet they do not sacrifice utility. The toilet is expensive in comparison to other similar units that can be purchased for less than $100. However, you will get something that will continue to serve you well for many years to come.

If you decide to go with this toilet, you should anticipate receiving praises when you have overnight visitors. Even in a space as constrained as a powder room, it manages to exude an air of incredible sophistication because to its uncluttered design and small structure.

Compared to porcelain units that do not have a coating, the vitreous china enamel coating on the toilet makes it more durable and glossy. It also has a seat and lid that can be closed and opened with ease. The bowl has a rim around it. The unit as a whole is a single piece, with the exception of the lid. This type satisfies the requirements of the Americans with Disabilities Act (ADA) in terms of the bowl’s form and height, so you don’t have to worry about anybody in your household who is physically impaired or elderly.

The weight of the toilet, which is 90 pounds, makes it rather hefty. However, it is feasible for a single person to set it up on their own without the need for any other assistance. Simply adhere to the instructions about the measurements, and when the adapter has been installed, hoist the toilet onto the assembly.

The lid of the tank does not rest securely on top and may be moved with some effort from its position there. Toto attaches it to the tank with a Velcro strap, ensuring that it will not move until you deliberately move it.

It is remarkable how well the toilet rinses all of the components of the bowl and flushes away the trash. There are two release points that, when activated, cause the water to swirl around the bowl and clean all of its individual components. The application of the SanaGloss finish ensures that the bowl will remain clean for an extended length of time. Because the finish inhibits the development of bacteria and mold, only a minimal amount of stains will be left behind. Make use of some mild cleaning chemicals if you want the shine to remain intact.

You won’t have to deal with many instances of clogging and overflowing when you use this toilet. Even if you flush the toilet two or three times while it is clogged, the water will not overflow. This is due to the fact that each flush only causes the toilet to emit 1.28 gallons of water.

The twin cyclone flush mechanism is one that is very effective and was given the name “Tornado flush” by Toto. The amount of water used is in accordance with the criteria for earning the EPA WaterSense certification. The main drawback is the very noisy flushing, which is made much more audible when it occurs at night.



The American Standard Champion 4 is a one-piece toilet that is ideal for anybody who is just seeking for a toilet that performs very well. Although it does not come with a large number of clever or sophisticated features, it is equipped with high-quality technology that allows it to exceed those of its rivals. Additionally, because to its small size, it is an excellent choice for even the most constrained of bathrooms.

The effective flushing mechanism is only one of the many features that contribute to the greatness of this one-piece toilet. The American Standard Champion 4 comes standard with a flush valve that is 4 inches in diameter and is capable of readily pushing water at a rate that is three times quicker than a conventional two-piece toilet. Because of its huge trapway, it is also capable of moving solid wastes that are 70 percent bigger than the typical toilet. This eliminates the need for you to flush your toilet twice, which would result in a greater amount of water being used. In addition to this, it ensures that your toilet will not get clogged under any circumstances.

With this one-piece toilet with an EverClean surface, you can be certain that your toilet will never get dirty. This is made possible by the bowl’s non-sticky surface, which prevents waste from sticking to the bowl, as well as the bowl’s antimicrobial surface, which can be found on both the inside and the outside of the bowl. Because of these cleaning characteristics, cleaning is now both simple and quick.



The T-0008 is an improved model of two of WoodBridge’s earlier and more successful versions, the T-0001 and the T-0019. This is a more recent toilet. The WoodBridge T-0008 Luxury Bidet Toilet seat provides a higher level of comfort and is designed with features that are on the cutting edge of technology. It has so many different possibilities that you may tailor your own level of comfort to suit your preferences. The cost of the toilet is not cheap; but, given that it is a high-end product, this is to be expected.

The T-0008 looks to have been built specifically for a contemporary restroom due to its modern appearance, which includes an enlarged bowl and a streamlined shape. The low-profile device has a height of 14 inches and provides a sitting height that is suitable for the vast majority of individuals. The extended bowl has dimensions of 28.5 inches by 27.5 inches, making it suitable for use by even the largest of individuals.

It is a wonderful touch and a positive feature that the brand’s one-piece unit comes with an innovative bidet seat that was built particularly for that unit. The bidet function is not included on a large percentage of toilets in this price range. The T-0008 is a wonderful piece that would be an asset to any bathroom because of its high-quality structure as well as its immaculate workmanship.

The equipment comes with an installation instruction booklet that provides illustrated step-by-step guidance. The document is included with the purchase. Nevertheless, due to the fact that the device weighs 134 pounds, you will need the assistance of one more person. Before mounting the unit onto the bolts, make sure that the T-adapter and the hose leading from the bidet seat have been attached to the rear of the toilet, and that the line has been connected to your home’s primary water supply.

The T-0008 is loaded with several cutting-edge technologies that make routine tasks like cleaning and flushing a breeze to do. The heated seat has a temperature control dial with five different settings, in addition to a heater that supplies warm water and is constructed with a contoured seat for optimal comfort.

The bidet seat is equipped with some of the most effective functions for maintaining personal cleanliness. In addition to the three different wash choices, there is also the capability to alter the water pressure for improved cleanliness. The option to clean with warm water may be accessed with the press of a button. To ensure a thorough cleaning, the nozzle located under the seat will spray water in a pulsating or oscillating pattern. After you have finished washing, a self-cleaning function will automatically clean and disinfect the nozzle for you, so you don’t have to worry about keeping it sanitary. Lastly, utilize the function of the air dryer to finish drying yourself off.

It is simple to clean a one-piece toilet, and the T-0008 makes this chore even simpler by including a mechanism that allows the bidet toilet seat to be detached from the tank in a matter of seconds.

When the toilet is flushed, 1.28 gallons of water are discarded, which not only helps save water but also is sufficient for cleaning away garbage. Do you want to reduce your electricity expenses by a greater amount? Put yourself in a state of mind to save energy!

Additional features include an integrated LED light that can be used throughout the nights and a limited guarantee on the bidet for a period of two years.



The Swiss Madisson SM-1T256 Carré is a toilet that has a square design and blends beauty with water economy in a single product. Because of its unusual design, it will provide you with additional space to sit on while also giving your bathroom a more contemporary appearance. Because it has a dual flush mechanism, it is one of the one-piece toilets that we studied that is the most environmentally friendly.

Despite its inviting appearance, the toilet in question does not comply with ADA standards. It has a comfort height of 15 inches, which is the same as the height of the majority of toilets on the market today. The glazed skirted trapway and 12-inch rough-in measurement provide for simple maintenance of the dual-flush toilet’s other convenient features. The outside is composed of totally grazed ceramic, which gives it a brilliant shine; also, it has a quick-release soft-closing seat, which provides you with additional comfort. A toilet has almost everything that one would need.

In contrast to the majority of one-piece toilets available on the market today, the Swiss Madisson SM-1T256 Carré includes a gravity-assisted flushing mechanism that is very effective. This mechanism of flushing is quite effective, and the tank will automatically replenish itself within a few minutes in the event that you need a second flush. If you have the dual-flush option, you may flush liquid waste with the smaller 0.8 gallon per flush capacity while flushing solid waste with the larger 1.28 gallon per flush capacity.

This one-piece toilet is not only simple to install but also simple to use. If you are looking for a one-piece toilet that has an antique look but a contemporary design, this is an excellent option to consider.



KOHLER K-4007-47 If you have a little bathroom and are looking for a toilet that is both attractive and functional, you may consider purchasing a San Souci model. The toilet does not have SMART capabilities, but it has a current appearance thanks to its streamlined form and elegant curves. Additionally, it performs well because to its powerful AquaPiston technology, which distributes water evenly throughout the whole of the bowl.

This one-piece toilet has a flushing capacity of just 1.28 gallons, which is much lower than the usual flushing capacity of contemporary toilets, which is 1.6 gallons, and the flushing capacity of historic toilets, which is 3.5 gallons. When it comes to your monthly payments, this indicates that you will have a lot more money saved up at the end of the month as a result. Despite this, one should not draw the conclusion that the flush is insufficiently effective. Since of its AquaPiston technology, you won’t need to flush the toilet twice because it’s strong enough.

This space-saving one-piece toilet has dimensions of 25.6 inches by 16.75 inches by 24.25 inches, and it has an extended bowl with some nice curves on the edge as well as a flush lever that is chrome-plated. The compact size of it ensures that it won’t take up too much space in your powder room, which means you’ll still have plenty of room to stretch out and get comfortable. The superb design of the KOHLER K-4007-47 San Souci is further enhanced with a soft-closing seat, which will shut the lid without the need to smash it. This is just one of the many ways that this model excels.



Because Toto is widely considered to be one of the most trustworthy brands in the toilet business, you can rest certain that the TOTO UltraMax II will provide you with a superior experience in the bathroom. However, the fact that this one-piece toilet comes from a well-known brand is not the only advantage of purchasing it; it also has a great many other advantages. This is everything you need if you are seeking for a one-piece toilet that is not only attractive but also quite effective.

The streamlined appearance of this particular style of toilet is the very first thing that catches your eye about it. All of its enticing attributes have been crammed into a single, space-saving element of the toilet, which, in addition to reducing clutter, highlights the style of your bathroom. The CEFIONTECTTM glazing, which gives it a more refined and high-quality finish, contributes further to this product’s overall superiority. The coating has another beneficial property, which is that it prevents any waste from clinging to the bowls. This is a really cool feature.

The fact that this one-piece toilet meets all ADA requirements was another feature that won our praise. It is able to accommodate all users, including senior citizens and those with physical disabilities. Toilets that comply with ADA standards provide the people for whom they are designed a level of height comfort that is difficult to find elsewhere. In addition to this, it complies with both the CEC and CalGreen, so you can be certain that you are purchasing a high-quality toilet.

Additionally, you will like the twin cyclone flush technology that it have. This technique employs a strong centrifugal motion to clean both the inside and outside of your bowl, leaving it looking as good as new. In addition, the tank may be refilled in a matter of seconds for added convenience.



If you are searching for a lovely one-piece toilet for your little bathroom, you might consider purchasing the Kohler San Souci. It is an excellent option. The compact toilet may not have any high-tech features, but it has an impressive number of useful functions despite its lack of size. It has a classy appearance and would look great in either a modern or a classic bathroom.

The gorgeous toilet, which has an expanded bowl, graceful curves on the tank, a flush lever plated in chrome, and a compact structure, might be a perfect complement to any project involving the refurbishment of a bathroom. The distance from the back of the wall to the front side is just 25 5/8 inches. When it comes to maximizing space in a compact or medium-sized bathroom, a smaller footprint may make all the difference.

The San Souci bowl has a front that is rounded and this helps to reduce the amount of space that is taken up by the bowl overall. When the bathroom is on the smaller side, the space-saving design will allow you to have more area to stretch out your legs.

The fact that the seat may be closed softly and without any slamming movement is a significant benefit of having a soft-close seat. Installation is made noticeably less difficult by the presence of quick-release hinges, quick-attach hardware, and rubber bumpers. Because the design of the canister exposes very little of the seal material, the performance will be completely leak-proof.

Since of its one-piece construction and vitreous china finish, this toilet is more simpler to maintain and clean than others of its kind because it accumulates less stains.

One of the available options at San Souci is a single flush that is WaterSense certified and uses 1.28 gallons of water. When compared to a toilet that holds 3.5 gallons of water, it saves roughly 16,500 gallons of water annually. A standard toilet holds 3.5 gallons. The use of water is reduced by 20% in comparison to standard 1.6-gallon toilets.

The San Souci generates a forceful flush by using AquaPiston technology, which also pushes water to the bowl from all angles, ensuring that it is properly scrubbed. Because it is a powerful flush, the toilet does produce some noise, but it is not loud enough to be obnoxious.


Both one- and two-piece toilets have several characteristics in common with one another. They both have the same installation technique, come with flushing systems that use the same amount of water, have interior features that are almost comparable to one another, and consume the same amount of water. There is no discernible difference between the two in terms of their flushing power or efficiency.

The main disadvantage of a toilet that is made up of a single piece is that the whole fixture has to be replaced if even a single component breaks. Because the tank and bowl of a two-piece toilet are distinct from each other, you may repair just the portion that is broken. This makes a two-piece toilet more affordable than a one-piece toilet. On the other hand, the two-piece design lacks some of the benefits that are offered by the one-piece devices.

Sleek Profile

The one-piece units have a streamlined construction and superb aesthetics, making them appear like they are a wonderful fit for modern bathroom decorating. In addition to this, they are the finest option when there is a limited amount of room.

The tank and bowl of a one-piece toilet are combined into a single unit, which allows for more efficient use of the bathroom’s floor space. For the tank to be supported, you will not need to place any clamps or drill any holes on the wall.

Easy Cleaning

The ease with which one-piece units may be maintained and cleaned is the primary benefit that comes with having such units. If you have ever dealt with the hassle of cleaning a two-piece machine, you will really appreciate the ease of this one. Mold and bacteria are likely to have already established a colony in the portion that connects the two other parts. If you let it go uncleaned for too long, it will turn into a chaotic mess. It is rather difficult to clean the crevices without removing the tank, and the region where the bowl connects to the tank has a connection that might leak.

Because there are no nooks or crevices in which filth and grime may hide, one-piece toilets are more simpler and quicker to clean than their two-piece counterparts. Since the tank and bowl are essentially made of the same piece and there is no seam between them, there is no possibility of a leak occurring.

Extremely long-lasting

When there are fewer pieces that link together, a piece of machinery or other apparatus is more durable. Because it is made from a huge, singular piece of porcelain, a one-piece toilet is designed to survive for a very long period without developing any leaks.

A two-piece version, on the other hand, has a rubber gasket that seals the tank but wears down with time, causing it to develop leaks that let water out.


We finish off by answering some of the common questions about the best one piece toilets:

best single piece toilet

Q1. Is the one-piece toilet more convenient?

A. One-piece toilets are often more difficult to move and more difficult to clean, but they also allow for less room for germs to thrive. Two-piece toilets are more adaptable to individual preferences in terms of desired designs and heights. This is because the tank may be removed from the bowl. Both types may come with additional features and options, such as attachments for bidets or water- and energy-saving low-flow options.

Q2. How should one-piece toilets be cleaned?

A. The cleaning process for a toilet that is made up of one component is simple. In point of fact, the vast majority of contemporary toilets are equipped with some kind of self-cleaning mechanism, which makes the process even less difficult. When it comes to cleaning the outside of the toilet, you may use a solution of water and vinegar on a wipe cloth. When it comes to cleaning the inside of the bowl, a chemical detergent can be the most effective option. At the very least, you should clean your toilet once every seven days on average.

Q3. Are there any drawbacks to using one piece toilet?

A. The weight of one-piece toilets is much higher. This is due to the fact that a one-piece component includes everything in a single mold, but a two-piece component must be disassembled before it can be moved, which doubles its weight. It could be more difficult to move, and the shipping expenses might end up being much greater.

Q4. Can a one-piece toilet take the place of a two-piece toilet in my bathroom?

A. In the majority of instances, the installation of a one-piece toilet may successfully take the place of a two-piece toilet without turning into a major undertaking. Make sure that the rough-in dimensions and bowl size of the new toilet match those of the one that is already installed in your bathroom.

Q5. What is the optimal height for a toilet?

A. Rims that are standard height are 14 to 15 inches from the floor and should work well for persons who are shorter than that. If you are above 6 feet tall, you should look for chair height toilets, which have a seat that is at least 17 inches above the floor.

Q6. Should the tank of a toilet be allowed to touch the wall?

A. In the vast majority of houses, the bathroom has a toilet that is recessed into the wall. It’s possible that there will be a space between your wall and its tank on occasion. You should measure the length of the gap, despite the fact that it is not anything that should cause you any anxiety. If it is smaller than two inches, there shouldn’t be any issues with it.

Final verdict

If you focus in on this area, you’ve already done quite a decent degree of filtering out among your selections. However, you may still need to pick among the top one-piece toilets. You’re almost there with finding the one, and we’re certain that the advice and suggestions we’ve given you will be of tremendous assistance to you in your endeavor.
