Toilet’s Main Components

Before we examine the differences between the two toilet designs, here are the main components of a toilet:


The part of the toilet which makes it rise above the ground is the pedestal. It is also the foundation where the toilet is built upon. Most western-style toilets have pedestals, while a few toilets manufactured in Asia do not have them.


Perhaps the most known part of a toilet is its bowl. This is where the toilet business happens. The bowl is responsible for collecting the waste and providing a pathway to the septic tank or local sewer system.


The powerhouse unit of a toilet is its tank. It has a supply of water that provides the necessary water pressure to flush the toilet. Besides that, it is also where other internal components of the toilet are operating mechanism are located.
