Is Your Toilet Flange Too High? Here’s How To Fix It!

A toilet flange is a crucial component that connects the toilet to the drainpipe, ensuring a secure and leak-proof connection. However, if the toilet flange is too high, it can lead to installation problems, leaks, and even toilet bowl instability. Determining whether your toilet flange is too high is essential for addressing these issues effectively.

Signs of a Toilet Flange That Is Too High

• Uneven or wobbly toilet bowl: A toilet flange that is too high can cause the toilet bowl to sit unevenly or wobble, creating an unstable and uncomfortable experience.
• Difficulty installing the toilet: If the flange is too high, it can be challenging to fit the toilet bowl onto the flange and secure it properly.
• Leaks around the base of the toilet: A high flange can create gaps between the toilet base and the floor, allowing water to seep out and cause leaks.
• Visible gap between the flange and the floor: If you notice a noticeable gap between the flange and the floor, it’s an indication that the flange may be too high.

How to Check if Your Toilet Flange Is Too High

To determine if your toilet flange is too high, you can use a simple measurement method:

1. Measure from the floor to the top of the flange: Using a measuring tape, measure the distance from the finished floor to the top of the toilet flange.
2. Subtract 1/4 inch: Subtract 1/4 inch from the measurement you obtained in step 1. This is the ideal height for the top of the toilet flange.
3. Compare the result: If the actual measurement exceeds the ideal height by more than 1/4 inch, it indicates that your toilet flange is too high.

Fixing a Toilet Flange That Is Too High

There are two main methods for fixing a toilet flange that is too high:

1. Using a Flange Extender

• Purchase a flange extender: A flange extender is a device that can be installed on top of the existing flange to raise its height.
• Install the extender: Follow the manufacturer’s instructions to install the flange extender securely.
• Reinstall the toilet: Once the extender is installed, you can reinstall the toilet bowl.

2. Resetting the Toilet Flange

• Remove the old flange: Carefully remove the existing toilet flange using a reciprocating saw or a utility knife.
• Clean the floor: Clean the area where the old flange was installed to remove any debris or sealant.
• Install the new flange: Install a new toilet flange at the correct height using appropriate fasteners and sealant.
• Reinstall the toilet: Once the new flange is installed, you can reinstall the toilet bowl.

Other Considerations

• Floor type: The type of flooring can affect the height of the toilet flange. If you have a thick flooring material, you may need to adjust the flange height accordingly.
• Wax ring: The wax ring that seals the connection between the toilet and the flange should be of the appropriate thickness to compensate for any variations in flange height.
• Professional assistance: If you are unsure about how to fix a toilet flange that is too high, it’s advisable to seek professional assistance from a licensed plumber.
