Toilet Installation Essentials: Structural Adhesive vs. Silicone Sealant

When installing a toilet, glue is often needed for fixing it, but many people do not know whether to use structural adhesive or silicone sealant. Let's take a look at how to install a toilet and what to pay attention to.

Structural Adhesive or Silicone Sealant for Toilets：

It is generally recommended to use silicone sealant. The area where silicone sealant is needed is the connection between the bottom edge of the toilet and the floor. Due to the high humidity in bathrooms, silicone sealant has superior water resistance and weather resistance compared to structural adhesive, making it the preferred choice.

What to Pay Attention to When Installing a Toilet：

1、Before installing the toilet, it is essential to choose a suitable model; otherwise, it may affect usability or even result in installation issues. When selecting, measure the rough-in size beforehand and purchase accordingly.

2、During the installation, check whether the floor is level. If the toilet is installed on an uneven surface, it will be challenging to secure it, possibly leaving gaps. This could allow unpleasant odors from the sewage system to return into the room, affecting the user experience.

3、When installing the toilet, first determine the position of the toilet. Mark the position of the toilet's drain outlet and the floor's sewage outlet. Then, use a power drill to make holes, install expansion screws, and finally seal the base of the toilet with silicone sealant.

4、Once the toilet is secured, do not use or expose it to water for at least 24 hours to allow the silicone sealant to cure thoroughly. Also, check the functionality to ensure all components are working properly, that the drainage speed is adequate, and that there are no blockages, as these can significantly affect future use.

summary：To sum up, we have discussed whether to use structural adhesive or silicone sealant for toilets, as well as what to pay attention to during installation. It is important to fix the toilet with silicone sealant to prevent unpleasant odors from the sewage system from entering the home, especially since it is difficult to achieve a perfect seal between the toilet and the floor.
