How to Choose a Toilet for a 280mm Tile Gap: A Complete Guide

When it comes to installing a toilet, the distance from the wall (known as the "rough-in") is a crucial factor to consider. If your rough-in measurement is 280mm after tiling, here’s how to choose a toilet, along with some tips for toilet selection.

Choosing a Toilet with a Rough-In of 280mm：

In this case, you should select a toilet with a rough-in measurement of 280mm or less. Since there may be a 10mm installation error, using a toilet with a rough-in greater than 280mm would require you to open the wall to install part of the tank inside it to compensate for the distance, or install an offset flange; otherwise, proper installation may not be possible.

The rough-in measurement is vital for toilets because an incorrect choice can complicate installation. First, confirm the drainage system of your bathroom, then measure the distance from the center of the drainage pipe to the wall. This measurement will give you the rough-in distance, which you can use to select the appropriate toilet, reducing the chances of installation errors.

Toilet Selection Tips：

1、Measure the Rough-In Accurately

It’s essential to measure the rough-in accurately when purchasing a toilet, as this determines whether it can be installed properly. Additionally, consider installation tolerances—ideally, it should not exceed 1cm. Typically, toilets come with rough-in measurements ranging from 300mm to 450mm. However, since bathroom layouts vary significantly, the choice should be based on the specific dimensions of your bathroom.

2、Consider the Toilet Dimensions

The dimensions of the toilet are also critical for ensuring comfort during use. Generally, the footprint of a toilet is approximately 700mm by 400mm, so you should allow adequate space of about 800mm by 1280mm for installation. The 800mm dimension accommodates comfortable legroom while sitting, and the 1280mm dimension provides adequate space for a comfortable seating posture.
