What Is a Rimless Toilet?

Rimless toilets are a kind of toilet that has no rim around the bowl. It was first introduced in 2002 by a Japanese company. After many years of perfection and advancement in craftsmanship and design, rimless toilets have captured the attention of customers around the globe and therefore made their way into and livened up innumerable households.

How Do Rimless Toilets Work?

With cutting-edge engineering and compact designs, these rimless toilets use an advanced technique known as “cyclone flushing” and offer an effective and efficient way to get rid of waste. By replacing the curved rim around the inside of the bowl with a flat surface, rimless toilets direct water into the trapway below, creating a wider area for waste to flow away quickly. This process also helps reduce any unsightly buildup of debris since it is strictly swept away by water.

What Is the Difference Between Rimless Toilets and Standard Toilets?

The differences are manifest in mainly two aspects: appearance and flushing method. Here let’s see how do they perform: rimless toilet vs standard toilet.


Compared to traditional toilets with rims, the rimless toilets have no rims around the bowl, which makes it easier to clean and is also more hygienic than standard toilets. Rimless models are often seen as being more aesthetically pleasing too, as they create one continuous smooth curved line which is uninterrupted by an inner rim.

Flushing Mechanism

As for traditional toilets, the water flows into the bowl from underneath the rim, whereas for rimless toilets, the water flows horizontally and then vertically, forming a powerful and effective flush. This flush has enough power to clean the entire inner surface of the toilet bowl with little to no splashing.

Rimless Toilets Pros and Cons

As a new design, it is reasonably expected that rimless toilets will also have pros and cons, similar to anything else. Let’s see them below:

Pros of a Rimless Toilet

  • Rimless toilets are easy to clean

This type of toilet is particularly easy to clean since it has no rims, which can easily contain bacteria and grime, contributing significantly to bathroom hygiene. The rimless design also facilitates the cleaning process by allowing full contact with the inner surface of the bowl. On the other hand, traditional toilets are prone to accumulate grime and dirt under their rims, which has the potential to persist despite repeated cleaning sessions. Thus, rimless toilets have done a great job of simplifying the tedious task of cleaning and boosting bathroom hygiene.

  • Rimless toilets boast powerful flushes

Most rimless toilets on the market often utilize the advanced direct flush technique. This technique enables water to flow around the whole of the bowl, resulting in more powerful cleaning of the pan than conventional toilet suites. Thus, your toilet will become visibly cleaner after every flush. As a comparison, conventional toilets are sometimes criticized for their feeble discharge of water and consequently inadequate flushing. Needless to say, this can cause a lot of trouble for the user of the toilet, and has become one of the driving factors behind customers switching to the more advanced rimless toilets.

  • Rimless toilets are more aesthetically appealing

Rimless toilets feature a more modern and elegant look. As such, they are suitable for those who want a clean and minimalistic decor in their bathroom. On the other hand, traditional toilets often appear bulky in comparison, which could reduce the overall ambiance of a bathroom.

  • Rimless toilets are more water-saving

The special design allows rimless toilets to maximize the efficiency of flushing, which mainly involves two aspects: a more powerful flush and less water use. When efficiency increases, a better flushing effect can be achieved with the same amount of water. Therefore, we can truthfully say that rimless toilets are more water-saving.

Cons of a Rimless Toilet

Apart from the good sides, rimless toilets’ problems are also present, which include:

  • Rimless toilets have a tendency to splash if improperly installed

Although rimless toilets have done a lot to reduce splashing, it might still occur if improperly installed. For example, if the flush flow valve is not properly positioned, water splashing might ensue, creating a mess in your bathroom. Thus, it is recommended to do the installation with care.

  • Rimless toilets have a higher cost

As you might expect, rimless toilets can cost more than their rimmed counterparts, given their fancy designs. But the margin is usually small; rimless toilets generally cost just a little more than rimmed ones, which is certainly a relief.

  • Rimless toilets might have the potential to leak

If the model quality is poor, leakage can happen at times, which can definitely cause a headache. So it is vital to pay extra attention to product quality when purchasing rimless toilets. For example, you can consider toilet manufacturers that are known for exceptional product quality, such as MyHomeware, when you are in the market for rimless toilets.

Types of Rimless Toilets

Just as the case with traditional toilets, rimless toilets can largely be categorized as follows:

Rimless wall hung toilets

These toilets are completely hung on the wall, which means no contact with the floor happens. Therefore, the cistern and all the pipework are located inside the wall cavity. This results in a simplistic appearance for the toilet, which is quite aesthetically pleasing. This kind of design is suitable for those looking for a modern, clean look.

Rimless back to wall toilets

These toilets sit flush against the wall, and no gaps are present between the toilet pan and the wall. This type of design is particularly suited for cleaning since it excludes the possibility of grime and dirt building behind the pan. This kind of design caters to those who prioritize hygiene and maintenance.

Rimless close coupled toilets

The cisterns of these toilets are positioned on the back of the pan, forming one integral unit, reducing the space needed for installation. Therefore, this kind of design is a good choice to consider for those who are working with limited space.
