Can A Toilet Flange Be Higher Than The Floor? Here’s The Answer!

The toilet flange, an unsung hero in the plumbing realm, plays a crucial role in securing your toilet to the floor. However, homeowners may encounter a perplexing question: can a toilet flange be higher than the floor? This blog post will delve into the intricacies of toilet flanges and provide a comprehensive understanding of this plumbing conundrum.

What is a Toilet Flange?

A toilet flange is a metal or plastic ring that is installed on the floor and provides a solid base for the toilet to rest upon. It serves two primary functions:

1. Anchoring the Toilet: The toilet flange bolts hold the toilet securely to the floor, preventing it from wobbling or shifting.
2. Sealing the Connection: The flange creates a watertight seal between the toilet and the drainpipe, preventing leaks and unpleasant odors.

Can a Toilet Flange Be Higher Than the Floor?

Yes, a toilet flange can be higher than the floor. However, this is not the ideal scenario and can lead to several issues.

Consequences of a High Toilet Flange

• Uneven Toilet Seat: A higher flange can cause the toilet seat to slope, making it uncomfortable to sit on.
• Plumbing Problems: If the flange is too high, the toilet may not be able to drain properly, leading to clogs and backups.
• Aesthetic Concerns: A flange that protrudes above the floor can be unsightly and detract from the bathroom’s overall appearance.

Why Might a Toilet Flange Be Higher Than the Floor?

• Flooring Installation Errors: Installing flooring over an existing flange without removing it can raise the flange’s height.
• Subfloor Damage: If the subfloor has rotted or buckled, it can push the flange upward.
• Improper Flange Installation: Installing the flange incorrectly, such as not setting it flush with the floor, can lead to a high flange.

How to Fix a High Toilet Flange

Fixing a high toilet flange requires addressing the underlying cause:

• Remove Flooring: If flooring was installed over the flange, it needs to be removed and the flange reset flush with the floor.
• Repair Subfloor: If the subfloor is damaged, it must be repaired or replaced before installing a new flange.
• Reinstall Flange: If the flange was improperly installed, it should be removed and reinstalled correctly.

Preventative Measures

• Plan Ahead: Before installing flooring, check the height of the toilet flange and make any necessary adjustments.
• Protect the Flange: When installing subflooring, use shims or spacers to prevent the flange from being pushed up.
• Hire a Professional: If you are unsure about how to fix a high toilet flange, it is advisable to consult a licensed plumber.
