What is the Standard Size of a Toilet？

What is the size of a toilet? As a beginner in purchasing toilets, you may not be very familiar with toilet sizes. But don't worry, let me briefly introduce some related knowledge about toilets.

Toilet Size：

The size of a toilet generally ranges from approximately 200mm to 400mm, with most households using a toilet size of around 300mm. Meanwhile, the size of the drain pipe is the same as that of the toilet, with an outer diameter of 110mm for the waste pipe. The distance from the center line of the toilet tank to the front of the toilet seat is typically about 520mm, and the width is between 340mm to 390mm. The footprint dimensions of the toilet are usually 700mm × 400mm. Therefore, you should reserve a space of 800mm × 1280mm for installing a toilet.

In addition to the dimensions of the toilet itself, it is essential to have proper installation dimensions, as poor installation can affect comfort regardless of how well the dimensions fit. The 80mm mentioned refers to the comfortable space for the feet when sitting on the toilet, while the 128mm pertains to the comfortable forward tilt of the body. An appropriate toilet height enhances both physiological needs and overall comfort. Through experimental testing, it has been found that the distance from the bent lower leg to the bathroom floor is approximately 30mm to 80mm.

Toilet Purchase Tips：

1、Weight

Heavier toilets generally have better quality. The weight of an average toilet is around 50kg, while a high-quality toilet weighs about 100kg. Additionally, heavier toilets have greater density and meet quality standards. A method for testing toilet weight is to lift the tank lid with both hands to gauge its weight.

2、Outlet

A toilet should have only one waste outlet. Most brands today may have two to three outlets, but having more outlets might affect flushing power.
