Understanding Toilet Sizes: The Three Standard Dimensions You Need to Know

Toilets are an essential part of home life, and when purchasing and installing one, it is important to consider various detail issues to ensure proper usage in the future. The three standard sizes of toilets are as follows:

一、Toilet Sizes

The three standard sizes of toilets are 280mm, 290mm, and 300mm. Most bathrooms are designed based on standard dimensions, and the size of the toilet is related to the rough-in distance, which typically ranges from 200mm to 400mm. The rough-in distance commonly used in households is 300mm, and the pipe size for the toilet is the same, with an outer diameter of 110mm.

二、When selecting a toilet, there are several considerations:

1、Weight of the Toilet: When purchasing, you can weigh the toilet. The heavier the toilet, the better it usually is, as a heavier toilet often has a higher density and better quality.

2、Toilet Seat: It is advisable to avoid toilet seats made of PP material as they are prone to yellowing. For smart toilets, this issue does not exist. Additionally, the toilet seat should be easy to disassemble, preferably with a stainless steel design for easy cleaning.

3、Design Around the Toilet Base: The design around the base should be fully enclosed and curved, making it easier to clean. A non-fully enclosed design may collect dirt and odors more easily.

4、Height and Shape of the Toilet: It is crucial to sit on the toilet in person to determine if it is suitable, especially for taller individuals. You need to sit and assess the comfort of your thighs and feet.

5、Inspecting Toilet Water Components: Quality bathroom fittings are made from high-quality plastic, which offers excellent water resistance and corrosion resistance.

6、Glaze Quality: Pay attention to the toilet glaze, which should be bright, smooth, and saturated. For the drain outlet diameter, choose a larger diameter for better waste disposal, lower chances of dirt accumulation, and reduced risk of blockage.

summary：

the three standard sizes of toilets are 280mm, 290mm, and 300mm. Most bathrooms are designed based on these standard dimensions.
