Home / Blog Center / Chargers / Toilet Installation Guidelines: Standard Distance from Wall
30/12/2024 | Hawkrown
Before purchasing a toilet and carrying out plumbing renovations, it is essential to know the distance from the toilet to the wall, commonly referred to as the toilet rough-in distance. Let's take a look at the specifications for this dimension.
一、Specifications for Toilet Distance from Wall
The specifications for the distance from the wall to the toilet are 300 mm, 350 mm, 400 mm, and 450 mm, among others. When determining the toilet rough-in distance, it should be decided based on the actual size of the bathroom, as different households have varying bathroom sizes, which will influence the installation position of the toilet. The rough-in distance should be determined based on the bathroom design, with a standard 20 mm reserved for wall tile thickness. Therefore, the actual distance from the centerline of the toilet drain to the wall will be 320 mm or 420 mm, with a normal error of about 10 mm.
二、Considerations for Toilet Rough-In Distance
1、Measuring the toilet rough-in distance is straightforward; it involves measuring the distance from the center of the toilet drainage pipe to the wall. However, before measuring, it's crucial to consider the thickness of the wall tiles. For instance, if the rough-in distance is 400 mm, the actual rough-in distance will be 380 mm.
2、As mentioned, the rough-in distances of 300 mm, 350 mm, etc., are measured before tiling, so an additional 20 mm should be taken into account. For example, if the distance from the wall to the sewage outlet is 320 mm, we need to reserve 20 mm, which means we should purchase a toilet with a 300 mm rough-in distance.
3、The standard toilet rough-in distances are 300 mm and 400 mm, with a drain diameter of 110 mm. If the rough-in distance is between 275-375 mm, it is recommended to choose a toilet with a 300 mm rough-in. For distances between 375-450 mm, a toilet with a 400 mm rough-in is advisable. Generally speaking, a rough-in variance of around 10 mm is acceptable for installation.
