What Are the Standard Toilet Dimensions?

There are many types of toilets, and when choosing, it's important to consider the actual conditions in your home to determine which size is most appropriate. Below, I'll discuss the dimensions of toilets.

Toilet Dimensions：

1、Overall Dimensions

For tank-type toilets, the typical length is around 700 mm, the height is about 700 mm, and the width ranges from 300 to 500 mm.

For one-piece toilets, the height from the top to the bottom is approximately 750 to 830 mm, the height of the seat is around 360 to 430 mm, and the width is about 680 to 730 mm.

For children's toilets, the dimensions are approximately 530 mm in length, 285 mm in width, and 500 mm in height.

For smart toilets, the height is around 700 mm, the length ranges from 620 to 720 mm, and the width is roughly between 360 to 400 mm, with widths of 370 to 380 mm being quite common.

If it’s a wall-hung toilet, its dimensions are approximately 650 mm in length, 345 mm in height, and 740 mm in width.

2、Seat Height

The seat height is typically around 400 mm, which provides a comfortable sitting position. The seat height is measured from the lowest surface to the seat itself, and most of the dimensions are based on human height. Taller individuals may prefer a higher toilet.

3、Rough-In Dimension

The rough-in dimension depends on the outlet method. The rough-in for horizontal outlets is typically around 180 mm, while for floor outlets, it can be around 380 mm, 400 mm, or 580 mm, etc. When measuring the rough-in for an unfinished room, be sure to subtract the dimensions that will be occupied by tiling the wall.

In summary：the dimensions of toilets can vary significantly. It’s essential to consider various aspects when determining the size, so you'll know the exact dimensions needed. Before purchasing, be sure to understand the dimensions allocated in your home to select the most suitable size. I hope this information is helpful to everyone.
