Cause Description Solution
Incorrect Installation The toilet flange may have been installed too high during the construction or remodeling process. Reinstallation of the flange to the correct height or using alternative methods to correct the issue.
Raised Bathroom Floor The bathroom floor might have been raised, causing the toilet flange to be positioned higher than the recommended level. Raising the flange to match the new floor height or adjusting the floor level to align with the flange.
Thick Flooring Materials The use of thick flooring materials such as multiple layers of tiles or excessive underlayment can result in an elevated flange. Adjusting the flange height by adding suitable spacers or replacing the flange with a higher one to accommodate the flooring thickness.

Using Cement

When it comes to filling a high toilet flange gap, there are a few options to consider. One popular choice is cement, known for its durability and ease of use. However, the downside is that it takes time to fully harden and set, which can be a hassle.

If you’re looking for a quicker drying time, epoxy putty or silicone caulk might be worth considering. Keep in mind that while these alternatives may dry faster, they may not be as durable as cement.

Using Grout

Opting for grout as a solution for filling the gap left by a high toilet flange presents itself as a viable and practical choice. Its ease of use and ability to create a seamless finish certainly make it an attractive option. Additionally, grout possesses the capability to effectively fill gaps, ensuring a secure and stable installation.

However, it’s important to acknowledge the drawbacks. Compared to other materials, grout requires a longer drying time, potentially causing delays in the installation process. Furthermore, it may not possess the same level of durability, potentially leading to cracks and subsequent leaks over time.

To ensure a successful application of grout, it is essential to adhere to recommended techniques and allow the substance to fully dry before utilizing the toilet. It is crucial to carefully weigh the advantages, disadvantages, and challenges associated with grout before settling on it as a filler. Seeking the guidance of a professional is always a prudent course of action.
