Toilet Hole Spacing: What You Need to Know

When it comes to installing a toilet, there are several important issues to pay attention to in order to avoid problems that could affect its use. Let's take a look at what the toilet rough-in distance is.

What is the toilet rough-in distance？

The common rough-in distances for toilets are typically four types: 30cm, 35cm, 40cm, and 45cm. The rough-in distance refers to the length from the center of the toilet's drainage outlet to the wall. This measurement is a crucial standard for selecting a toilet; if the dimensions do not match, it can result in improper installation.

Additionally, when choosing the toilet rough-in distance, it's essential to consider the layout of the bathroom and the preferences of the user. In practice, it's important to leave an extra 2cm of thickness for the installation of wall tiles. If the wall tiles have already been installed, then this 2cm thickness does not need to be considered.

What to pay attention to during toilet installation？

1、Before installing the toilet, it is necessary to check the drainage pipe for any blockages. If it is clogged with mortar, waste paper, or dust, it must be cleared out before proceeding with the installation to avoid complications later on.

2、Prior to installation, also ensure that the center position of the drainage pipe is correctly identified. You can turn the toilet upside down to find the cross centerline for proper installation.

3、After the toilet is installed, a sealing ring must be installed at the drainage outlet, or a layer of cement mortar should be laid around the toilet to prevent any potential water leaks in the future.

4、Before installing the fittings in the toilet tank, make sure to flush the water pipes thoroughly with clean water. Then connect the angle valve and the flexible hose, followed by connecting the other fittings in order. Once installed, turn on the water source to check if everything functions correctly. If there are issues, they need to be addressed promptly.

In summary：this is an introduction to the toilet rough-in distance and what to pay attention to during installation. Have you understood these points? Measuring the rough-in distance at the beginning is crucial to ensure proper installation and minimize the chances of problems occurring, leading to a more reliable and worry-free usage in the future.
