Understanding Toilet Flange Sizes: A Comprehensive Guide

The importance of the toilet flange is evident; it serves a sealing function to prevent odors from circulating indoors. So, what are the different sizes of toilet flanges?

一、Toilet Flange Dimensions Explained: Choosing the Right Size

There are two sizes of toilet flanges：30 cm and 35 cm. When installed at the bottom of the toilet outlet, it not only provides a sealing effect, effectively preventing sewage from escaping the toilet to the pipeline and stopping sewage odors from rising, but it also serves a fixed purpose, preventing misalignment of the drain outlet and facilitating future maintenance.

二、How often should a toilet flange be replaced

The flange, commonly known as a sealing ring, is located at the bottom of the toilet outlet and mainly serves the sealing function. As long as there are no leaks or odors coming from the toilet, it does not need to be replaced. It should be replaced only when issues arise or when replacing the toilet itself.

三、Precautions for replacing a toilet flange

1、Choosing the flange

There are many flange models available in the market. When replacing, it is essential to choose a product based on the size of your home’s drain and the toilet outlet. It is advisable to opt for flanges from well-known brands, as they generally offer better quality, odor-sealing effectiveness, and longer lifespan.

2、Flange shape

When replacing, pay attention to the shape of the flange. Typically, it is best to choose a circular flange to ensure compatibility with the drain and outlet. Additionally, be mindful of the installation method or consider hiring a professional to ensure that the sealing effect is not compromised.

3、Flange installation

When replacing the flange, start by applying silicone sealant around the toilet outlet, then install the flange as required. This way, the flange will be more securely attached.
