Toilet Flange Too High? Here’s How to Fix It

Are you in the process of remodeling your bathroom and have discovered that your toilet flange is sticking out too much?

A toilet flange that is higher than the subflooring can lead to several problems, such as a rocking toilet and potential leaks.

In this article, we’ll explore the causes and consequences of a high toilet flange and provide you with practical solutions to fix the issue.

Whether you’re a DIY enthusiast or prefer professional assistance, we’ve got you covered.

Understanding the Toilet Flange

Before we delve into the solutions, let’s take a moment to understand what a toilet flange is and why it is essential.

Also known as a closet flange, the toilet flange connects the toilet bowl to the sewer pipe.

It acts as a funnel, directing wastewater from the toilet directly into the sewer pipe.

Additionally, the flange helps elevate the toilet to prevent damage to the bathroom flooring.

Consequences of a High Toilet Flange

An excessively high toilet flange can lead to various problems, including a wobbly toilet that can potentially leak water.

This constant rocking motion can cause the bathroom floor to warp and even result in the growth of mold and mildew.

It’s crucial to address a high toilet flange promptly to prevent further damage and potential health risks.

Fixing a High Toilet Flange

Now that we understand the importance of addressing a high toilet flange, let’s explore some effective solutions to fix the issue.

1. Raise the Bathroom Floor

One option to fix a high toilet flange is to raise the bathroom floor to level it with the flange.

While this method can be effective, it is time-consuming and may not be suitable unless you’re already planning a bathroom remodel.

It involves adding thickness to the flooring, which can be achieved by investing in thicker tiles.

To raise the bathroom floor, follow these steps:

1. Measure the difference between the flange and the floor.
2. Purchase floor tiles of roughly the same thickness as the height difference.
3. Lay down the flooring, ensuring it reaches the level of the flange.
4. Once installed, the toilet should no longer wobble.

2. Use Grout to Fill the Gap

If you’re looking for a more cost-effective solution that doesn’t require a complete bathroom renovation, you can use grout to fill the gap between the flange and the floor.

Grout is an excellent material for this purpose and can be applied easily.

Here’s how you can use grout to fix a high toilet flange:

1. Mix the grout by combining one part grout with six parts water.
2. Place rubber shims under the toilet to prevent movement during the grouting process.
3. Pack the mixed grout into the gap underneath the toilet using a small applicator.
4. Allow the grout to dry for at least 24 hours, spraying water on it periodically to aid in curing.
5. Remove or trim any stuck rubber shims.
6. Fill in any remaining gaps with additional grout.
7. Tighten the nuts that hold the toilet down to ensure a secure seal.

3. Replace the Toilet Flange

If the previous methods are not feasible or effective, the last option is to replace the old flange with a new one that sits flush on the bathroom floor.

This solution requires more effort and skill but can provide a long-lasting fix for a high toilet flange.

To replace the toilet flange, follow these steps:

1. Carefully remove the toilet and set it aside.
2. Remove the old flange using a hammer and chisel or a variable-speed drill with a hole saw.
3. If necessary, remove the fitting inside the sewer pipe by scoring it with a sharp utility knife and popping it off.
4. Cut the sewer pipe if it extends too far from the floor, ensuring it is flush with the flooring.
5. Install the new toilet flange, drilling holes in the flooring if needed.
6. Set the toilet on the new flange, aligning the bolts with the holes in the toilet base.
7. Tighten the toilet down using the provided bolts and nuts, ensuring a secure and watertight seal.

Lifespan of Toilet Flanges

Toilet flanges, when correctly installed, can last for many years.

Manufacturers rarely specify a specific lifespan, as it can vary depending on various factors.

However, it’s worth noting that toilet flanges typically outlast the toilet itself and only require replacement if the toilet is replaced.

Leaks from the toilet base are often caused by worn-out wax rings rather than faulty flanges.

Conclusion

Dealing with a high toilet flange doesn’t have to be a daunting task. By following the methods outlined in this article, you can effectively address the issue and prevent further damage to your bathroom.

Whether you choose to raise the bathroom floor, use grout to fill the gap, or replace the flange entirely, make sure to prioritize the stability and functionality of your toilet.

Remember, addressing the problem promptly will save you from future repairs and potential health risks.
