Why Shimming a Toilet is Important

Ensuring the proper installation of a toilet is paramount to its stability and protection against damage. A vital step in this process is shimming, which not only prevents leaks and water damage but also maintains the toilet’s level position, thus preventing the escape of sewer gas into the bathroom. When toilets are incorrectly installed, they can become unstable, leading to leaks and damage to the flooring.

By utilizing shimming, the toilet is stabilized, eliminating any gaps between the toilet and the floor, thus preventing leaks and securing the toilet firmly in place. Additionally, shimming plays a crucial role in maintaining a level position for the toilet. An uneven toilet can create a gap between the toilet and the wax ring, allowing sewer gas to escape.

By employing shimming techniques, the toilet is ensured to be level and properly aligned, thereby avoiding any potential issues with sewer gas. In summary, the importance of shimming a toilet during installation cannot be overstated. It provides the necessary stability, prevents leaks and water damage, and ensures a level toilet that effectively prevents the escape of sewer gas.

Taking the time to properly shim your toilet will not only prevent future problems but also guarantee the longevity of your bathroom fixture.

Measuring the Gap

In the delicate art of shimming a toilet, precision reigns supreme. The key lies in accurately gauging the gap between the toilet and the floor, as this will determine the necessary size and type of shims. Begin by carefully assessing the toilet’s stability and alignment.
