In this article, we'll explore the causes, consequences, and solutions to the gap between the toilet and the wall.
Causes of the Gap
The gap between the toilet and the wall can be caused by several factors, including:
- Inadequate installation: If the toilet is not installed correctly, it can lead to a gap between the toilet and the wall.
- Settling foundation: Over time, the foundation of a home can settle, causing the toilet to shift and create a gap.
- Poor alignment: If the toilet is not aligned properly with the wall, it can lead to a gap.
- Wear and tear: As the toilet ages, the seals and gaskets can wear out, causing the gap to increase.
