toilet types

Every morning, we start our day with a trip to the bathroom, whether it be for brushing our teeth, taking an early morning shower, or using the loo. Your toilet is one of the most frequently used elements that make up your bathroom.

As with most inventions of mankind, these waste disposal devices have undergone changes over the years. In the modern era, there are so many different types of toilets to choose from, it can leave you in a perplexing situation.

Today, we will be looking at different types of toilets and their specifications, which will enable you to make a more informed decision when choosing one for your bathroom.

Components of a Toilet

Before we jump into different types of toilets, there are a few basic ideas you’ll need to familiarize yourself with in order to get a better understanding of your preferences.

Generally, toilets have four basic components: the bowl, tank, stop valve, supply tube. As we go deeper, we will look at other sub-components that allow the toilet to function. To begin with, the bowl is the round part of the toilet, which carries the water and waste.

Next, we have the tank, which is the large container that usually has a button we can push to start the flushing process. There are other working parts inside the tank, which we will look into later.

The stop valve is the knob that controls the water supply to the toilet. Using the knob, you can cut off the water supply to the toilet or turn it back on. This is usually located at the back to preserve the toilet’s aesthetics.

Finally, the supply tube is a pipe that is fastened to the stop valve, which transports freshwater from your pipelines to the refill tube of the toilet.

Components of a Toilet

Components inside the Tank

Now let’s take a deeper look into the mechanisms that lie within the toilet tank.

Refill Tube

This tube is responsible for making sure that the toilet never runs out of flushing water. When you use the flush, the tank is emptied, and the refill tube is signaled to fill the tank. Once the tank is filled, the refill tube will turn off the water supply.

Float Ball

This little device works as an indicator of when the tank is full. The float ball, as the name suggests, is a ball that floats on top of the water inside the tank. When the tank is empty, the water supply refills the tank automatically. The float ball indicates and signals when the tank is full to avoid overflowing of water.

Float Cup

In many of the newer models, the float balls have been substituted with float cups. This little device is situated on the valve body. Similar to the float ball, the float cup rises and falls depending on the water level. Once the float cup rises above a preset height, the valve on the refill tube is closed, thus preventing overflow.

Overflow Tube

When the refill tube fails to stop at the right time, the overflow tube steps in and drains the extra water.


When you press the handle or button to flush the toilet, inside the tank, a flapper is lifted. The lifting of the flapper results in suction, which causes the swirling movement of water you see inside the toilet bowl.

Trip Lever

Pressing on the handle to flush sets the trip lever in action. What it basically does is it lifts the flapper once you press flush so all the water in the tank can clean the bowl.


The trip lever and the flapper are connected to each other using the chain.

Components under the Bowl

Let’s get to know about the parts under the bowl.

Wax Ring

This is a very crucial component as it seals the toilet pipelines with the wall or ground (depending on the model). Once the toilet is placed on the wax ring, the wax dilates and creates an airtight seal.


The trap is what separates the toilet from your main sewage line. Traps come in different shapes, the two most common traps are the P-trap and the S-trap. The P-trap connects the toilet to your wall and is located at the back of the toilet. And the S-trap, however, exits below the toilet and is designed to connect to the floor.

Closet Bend

This part enables the waste materials from your bowl to exit your bathroom, and into the sewers.

With the toilet basics out of the way, we can now begin to explore all the different models of toilets that exist in the market. While it’s true that many toilets are closely similar to one another, their extra features are what make them unique and stand out amongst the crowd.

Types of Toilets

Below, we have listed down some of the best-known types of toilets with a key focus on their advantages, making it easy for you to decide on your purchase.

1. Two-Piece Toilet

The two-piece toilet is one of the most traditional yet well-known toilets in the market. What sets this toilet apart is its water tank, which is separate from the bowl. The water tank is, therefore, much larger and can hold a higher volume of water, providing you with a strong flush.

Two-Piece Toilet

Advantages of the Two-Piece Toilet

The advantages are mentioned below:


One of the key reasons this toilet is so widely known is because of its height. The toilet sits at a perfect height above the ground, enabling you to sit comfortably with less pressure on your ankles.


While it’s true that the two-piece toilet accepts defeat when it comes to a battle of aesthetics, it makes up for it in terms of durability. These toilets are thought to be practically indestructible and will last you for decades.

Availability of Parts

You would be pleased to know that the popularity of the two-piece toilet facilitates the availability of its parts in the repair shops. And you would be able to find replaceable parts in any store around town.

Advantages of the Two-Piece Toilet


The two-piece toilets cost relatively less in comparison to other types. And the key reason behind this is the fact that this design has been around for centuries and is growing obsolete.

Easy to Repair

It is a fact that this type of toilet is very easy to repair. So if somewhere down the line the toilet is malfunctioning, there is a high chance that you’d be able to fix it yourself.

Wide Range of Flushing Mechanisms

This toilet type has tons of other variations when it comes to the flushing mechanism. The most common flushing mechanism is known as gravity-feed. This mechanism uses gravity to flush down the waste while having a large water tank definitely aids its purpose.

If you’re looking for more power in terms of flushing, the pressure-assisted model will do the trick! The tank is fitted with a pressure system, which forces water from the tank into the bowl with air pressure. This is more efficient and also reduces the chances of clogging.

The dual-flush mechanism has recently caught the eyes of the crowd. It’s safe to assume these models are a mix between the gravity-feed and pressure-assisted mechanisms. This lets you choose between a half flush and a full flush, which saves water and is more efficient.

2. One-Piece Toilet

The one-piece toilet is said to be the counterpart of the two-piece toilet, mainly because of the similarities they share. As the name suggests, the one-piece toilet comes with the tank and bowl integrated into one body.

One-Piece Toilet

Advantages of the One-Piece Toilet

The advantages of the one-piece toilet are as follows:

Easy Installation

The one-piece design facilitates the easy installation of this toilet. Since the tank and the water bowl are not two separate entities, this toilet doesn’t require assembling.


The one-piece toilet designs are very minimalistic, making them versatile for any bathroom. As they don’t have large bulky water tanks attached to the bowl, they are very compact and aesthetically pleasing.


With the water tank and bowl housed into one unit, the one-piece toilet takes up much less space when compared to its two-piece counterpart.


This type of toilet is slightly lower in terms of height, making it easy for everyone to use. Kids usually have a hard time using two-piece toilets, mainly because they are shorter than adults. The one-piece design is comfortable, whether it’s you or your child that uses the loo.

Easy to Clean

In contrast to the two-piece toilet, the one unit housing of the water tank and the bowl in the one-piece toilet makes it easy to clean.

Soft Close Seat

Certain models of the one-piece toilet come with this subtle soft close seat enhancement. This feature keeps you away from the slamming sound of the toilet seat cover against the seat. Instead, the seat closes in slow and fluid motion when dropped down.

Dual Flush System

Most modern one-piece toilets come with dual flush systems that make efficient use of water while providing you with dual functionality. The half-flush button is used mainly when there is a liquid waste for which less water is needed. Alternatively, the full-flush button is ideal for stronger flushing action.

3. Wall-Hanging Toilet

These types of toilets are mostly available in commercial settings than in residential buildings. Wall-hanging toilets consist of a bowl which is mounted to the wall, while the tank is kept hidden behind the wall. One extra component they come with is the flush plate, which is placed on the wall above the bowl.

Wall Hanging Toilet

Advantages of the Wall-Hanging Toilet

Not every toilet brand makes this type. Here we have the pros of the wall-hanging toilet:


Where space is at a premium, your best bet is to get a toilet, which takes up the least amount of space. The wall-mounted toilet comes with a water tank which is fitted behind the wall, so all that remains inside the bathroom is the bowl. This maximizes space allocation and gives you more room for your other bathroom fittings.

Easy to Clean

With the tank housed inside the wall, the cleaning process of this toilet type becomes much easier. Most toilets of this type have a special coating on their surface, preventing mold from sticking to its surface.

Also, the suspended design allows you to clean the underside of the toilet easily. Generally, the bowl is all you need to pay close attention to when you’re scrubbing away!

Wall-Hanging Toilet
Universal Height

The wall-mounted toilet gives you the freedom to decide on the height measurement that works best for you. While the one-piece and two-piece toilet types both came with fixed height measurements, the wall-mounted toilet gives you more flexibility in this area.


With its sharpness in design, wall-mounted toilets give a touch of sophistication to your bathroom. Their sharp corners and minimalistic colors uplift the aesthetics of the bathroom as a whole.

Dual Flush System

Many modern models of the wall-hanging toilet come with the latest features, such as bidets or a dual flush system.

Depending on the waste to be flushed, you can either choose the half-flush option or the full-flush option. This dual-flush mechanism enables you to contribute to the environment by reducing water consumption.

4. Tankless Toilet

First glances to the name might make you wonder, how will the toilet function without a tank? Well, tankless toilets are directly connected to the pipe. The bowl in this type of toilet has an electric pump, which makes adds power to the flush.

Also, you should know that most tankless toilets with an electric pump require a continuous connection to your electric line. So while it does save water, it will undoubtedly add to your electricity bill.

Tankless Toilet

However, there are variants of the tankless toilet that do not have an electric pump built into the bowl. The flushing mechanism in those variants may not be as powerful as the ones with electric pumps. So, if you are going tankless, get one with an electric pump.

Advantages of the Tankless Toilet

Below are the benefits of a tankless toilet:

Easy to Clean

The majority of the tankless toilets are made of ceramic and SanaGloss, making cleaning almost effortless for you. There are little or no chances of molding to stick on the surface of your toilet due to the SanaGloss coating.

If you’re not tight on your budget, you might consider looking into some expensive models which have a built-in self-cleaning mechanism. With the help of a UV light system fit into the bowl along with an electrolyzed water system, these models guarantee you a clean toilet every time you walk into your bathroom.

Heated Seat

Since the tankless toilets have a constant electricity connection, they can provide you with additional features such as heated seats.

There are tons of benefits to having a heated seat mechanism on your toilet. The warmth helps your whole body relax and avoids tight muscles. Also, it provides better comfort and is considered to relieve pain for people diagnosed with arthritis or recovering from injuries.

Expensive models let you adjust the temperature of the seat as well!


One of the key benefits of using tankless toilets is its ability to minimize the use of water. The electric pump integrated into the bowl adds extra pressure to the water when flushing, therefore reducing the need for high volumes of water.

Automatic Deodorization System

Toilets tend to become smelly if they aren’t properly cleaned. Luckily for you, some of the models of the tankless toilets come with an automatic deodorization system. This mechanism integrates an air freshener and an air purifier within your toilet bowl, leaving a fresh smell in your bathroom every time you walk inside.

Emergency Flush

You know by now that it is best to get a tankless toilet, which houses an electric pump within the bowl. The question might arise, what do you do when there is a power outage? Well, nearly all tankless toilets come with an emergency flushing system.

What this mechanism does is store water in its reserve just in case your electricity line fails you, so you don’t have to worry about not using the bathroom in those situations.

Dual Flush System

In addition to being eco-friendly, the dual flush models of tankless toilets further facilitate its ability to save water. Allowing you to choose between a half-flush and full-flush will ensure the right amount of water is being used depending on the waste.


Eliminating the existence of a water tank makes this toilet one of the most compact designs in the market. These tankless designs take up the least amount of space in your bathroom while being overloaded with features that’ll pamper you every time you use the loo.


Given the fact that tankless toilets are priced higher than the usual one-piece and two-piece toilets, they are made to add a chic touch to your bathroom. With the right curves and smooth corners, these toilets give off a premium feel to your overall bathroom aesthetic.

5. Square Toilet

Square toilets are very similar to standard one-piece and two-piece toilets, but with a touch of modernism. The shape of the toilet seat is more close to being a rectangle than a square, which makes it stand out amongst the basic round shaped bowls. Undoubtedly the aesthetics of this boxy toilet is its most perceptible quality.

However, most people find square toilets to be uncomfortable, while others find it to be an absolute pleasure. Ultimately, its comfort depends on your preferences.

Square Toilet

Advantages of the Square Toilet

The advantages of the square toilet are stated below:


The sharp cut corners of this box-like toilet are what truly makes it stand out amongst a crowd of standard toilets. Its unusual yet sleek design creates a theme of its own in your bathroom. If you are considering putting in angular stainless steel sinks and other bathroom fittings, then the square toilet would fit just right.

One-Piece Design

It can be said that the square toilet is a variant of the one-piece toilet as it houses the water tank and bowl in one unit. This lets you enjoy benefits that are similar to the one-piece toilet type, such as compact space and effortless cleaning.

Large Bowl

Square toilets, because of their angular design, have a larger bowl compared to the standard toilets. The large bowl enables the toilet to catch more waste and dispose of it efficiently.

Soft Close Seat

To preserve the aesthetics and make the toilet experience more satisfying, most square toilets come with a soft-close toilet seat. In essence, the soft-close toilet seat enables you to get rid of the unpleasant slamming sound of the seat cover going against the seat.

Most toilet seat covers tend to crack with time due to the slamming of the cover on the seat. The softness of the closing action of the toilet seat, therefore, aids durability.


The square design is considered to be eco-friendly mainly because it has a smaller water tank. Larger water tanks like the two-piece toilets tend to use loads of water to wash down the waste. The square type toilets are built with smaller but efficient tanks, using less water when flushing.

Dual Flush System

Square toilets tend to have a weaker flush when compared to other toilet types. Having a dual flush system, in this case, can be very helpful, considering that the full-flush button packs an extra punch to the already weak flushing power. Nonetheless, the half-flush will be enough to get the job done.


Compared to traditional round shaped bowls, the square toilet’s rectangular bowl takes up less space in terms of width. This preserves the overall aesthetic of your bathroom while giving you some extra room beside the toilet.

6. Smart Toilet

With an exorbitant price tag, smart toilets are considered to provide you with a luxury experience. So, if you’re in the mood to spend some mad cash to pamper yourself in the bathroom, then this is the way to go.

Smart Toilet

Below are the pros of a smart toilet:


Aesthetics are given when you’re spending a lot on a toilet. Smart toilets, with their nice round finish and overall simplicity, will only add to the aesthetics of your bathroom. They also come with LED lights, which makes it truly stand out above all others.


These toilets aren’t as tall as the basic two-piece toilets, neither are they as low as the one-piece toilets. The universal height of the smart toilet is somewhere between the lines of the one-piece and two-piece model, making it ideal for adults and kids both.

Remote Control System

The toilets wouldn’t be considered “smart” if they didn’t give off a tech vibe, would they? All the features of the smart toilet are controlled by a small remote, giving you the ultimate power. While some remote controls have buttons, others have an LCD touchscreen, which adds to the whole premium feel of the toilet.

Automatic Lid Mechanism

Imagine walking into the bathroom and not having to touch the lid of the toilet. Fancy, right?
