14 Important Parts of a Toilet with Diagrams

Parts of a Toilet – Gone are the days when one would have to walk for miles to use an empty field, early in the morning to attend nature’s call. In today’s modern age and time, toilets are considered an essential interior that every house must possess at least to a minimum standard.

Understanding the Parts of a Toilet

Europe discovered the modern toilet system in the 16th century. The flush toilet was invented by Sir John Harrington, Elizabeth I’s godson, who invented a water closet with a slightly elevated water tank and a narrow downpipe through which water ran to flush the waste.

20% of toilets leak. You should be able to fix a toilet on your own or with the help of an expert plumber. You don’t want your house to become a stinky sewage water mess because your toilet overflowed or leaked and you couldn’t call a plumber in time.

It is helpful to know how each part functions when you need your toilet repaired in time and on – budget. Simple skills like these can assist you in resolving little difficulties, and they can also protect you from fraudulent plumbers who would take advantage of your lack of understanding in the field.

In this article, we’ve gathered information on toilet parts, their functions and usage with short and simple descriptions with corresponding diagrams for a better visual understanding. Read on to know more about the modern toilet in today’s world of the 21st century where Chamber pots exist only in museums. 

1. Parts of a Toilet : Trip lever

The trip lever’s purpose is to allow for easy and quick movement of the tub stopper. Basically, the lever is part of an apparatus that allows the stopper to be opened or closed, allowing water to be preserved in the tub or released into the drain.

2. Parts of a Toilet : The toilet flush handle

When you press down on the flush handle on the outside of the toilet tank in the right-hand corner, the trip lever rises. Inside the tank, a chain hangs from the trip lever, lifting the flush ball from its seat. The water from the tank flows into the bowl when the flush ball is lifted.

3. Parts of a Toilet : Wax ring

You can’t see it under your toilet, but there’s an invisible wax ring that seals the bottom of the toilet connected to the floor’s drain opening. An airtight and watertight seal can be created between the sewer line and the toilet with this wax seal. Water can seep out of the toilet’s base when it fails. A wax ring replacement can be a big hassle, but most toilets will eventually require a fresh one.

4. Parts of a Toilet : The Chain

In most cases, users operate tanks and valves by pressing a button, pulling a lever, or pulling a chain. When the tank is empty, you can empty it with the help of the flapper valve. If you pull on the handle, the trip level will move to the next level when you let go of it. This, in turn, tightens the chain and opens the flapper valve, allowing the chain to run freely.

5. Parts of a Toilet : Refill tube

There is a small flexible tube that runs from the water supply valve to the overflow tube, which is located in the centre of the tank. In the refill cycle, this tube sends a small bit of water down into the toilet bowl. If the bowl trap is sealed against sewer gases, it is vital to keep the standing water level in the bowl elevated.

6. Parts of a Toilet : Flush valve seal

Flushing the toilet involves removing the rubber flapper or tank ball from the toilet tank’s overflow tube. The overflow tube is located in the middle of the toilet tank’s flush valve, along with the overflow tube, hole, and rubber tank ball. This is because a broken flush valve prevents water from being held in the tank.

7. Parts of a Toilet : The float ballcock

The ballcock is a valve that is linked to a floating ball on top of a liquid by a detachable arm and automatically opens or closes a tap based on the height of the ball, typically in the storage tank of a toilet flush.

The Four main parts of a Toilet

Parts of a Toilet : Bowl

Toilet bowls and tanks are made of vitreous china, a type of clay.  Clays are hardened by first drying in the air and then firing (baking) in a very hot oven known as a kiln.  Because the entire clay body vitrifies or turns glassy, the toilet is actually waterproof and stainproof throughout its thickness and surface.

At this juncture, the bowl and the tank come together to form a single unit. When you flush the toilet, all the water in the tank is released, flushing out the dirty water in the bowl. The water in the tank immediately replaces it.

Rim holes

When you flush the toilet, the majority of the water leaves the bowl quickly. The bowl’s sides, however, are also washed with water, which washes away any debris that may have gotten stuck.

All of the water enters via small holes in the bowl’s edge. As a result of flushing power, the water circles and eventually finds its way down the drain pipe.


  • A toilet seat is a foldable unit that consists of a round or oval open seat and normally a lid and is fastened onto the bowl of a toilet when used in a sitting position. The seat can be used with either a flush or a dry toilet.
  • As a result of faeces, urine, and maybe vomit contaminating the toilet bowl water, there will be bacteria and other germs in the water droplets. Simply closing the toilet seat is the most effective technique to keep your bathroom clean. When the lid is closed, the distribution of droplets is reduced. Therefore, the toilet seat is an important organ to the toilet system to maintain proper hygiene.
  • You don’t want to sit directly on the cold toilet on a winter morning. This is why toilet seats are typically constructed of one of two materials. Plastic toilet seats are made of polystyrene, a type of thermoplastic. The far more common and lesser costing type of toilet seat is made of a wood-plastic composite.



A toilet flange is a circular piece of material with several holes in it. Bolts are inserted through these holes, securing the flange to the floor as well as to the sewer drain pipe. The toilet is then safely attached to the flange.


Shut-off valve

Usually located at the beginning of the flexible hose, the shut-off valve allows you to completely close the water inlet system. In the event that your toilet runs, leaks, or overflows in any way, the shut-off valve will put a short end solution to the immediate crisis. Until you figure out what’s really wrong, this will keep you occupied.

A flexible hose

It is a pipe that transports water to your toilet. This hose transports water from the tank’s main water supply and connects to the fill valve. 

Most hoses are made of plastic on the inside and are most often encased in steel mail. This keeps them flexible while also preventing any holes that could compromise the water pressure.

How does the Parts of a Toilet work?

When you flush the toilet by lowering the flush handle, the rubber flapper, also known as a float valve, rises. As a result, the water in the toilet tank rushes into the bowl and flushes the waste. As water flows from the tank to the toilet bowl, the flapper slowly sinks back down to rest on the flush valve. As the toilet flapper closes the water supply to the bowl, the toilet fill valve, also known as a ballcock, begins to refill the toilet tank with water in preparation for the next flush.
