How to Install a Wax Ring on a Toilet: A Complete Guide

The installation of a wax ring is a vital step in setting up a toilet, as it ensures a leak-proof and odor-free connection to the plumbing system. This guide covers the tools, materials, and steps required for a successful installation.


Safety and Preparation: Before starting, turn off the water supply, drain the toilet, and wear gloves for hygiene.

Tools and Materials: Essential items include a new wax ring, wrench, putty knife, sponge, and old towels.

Work Area Setup: Clear the space around the toilet and cover the floor with towels for spill protection.

Removing the Old Toilet

Step-by-Step Removal: Shut off the water supply, flush the toilet, disconnect the water line, remove bolts, and gently lift the toilet off the flange.

Avoiding Damage: Handle the toilet carefully to prevent porcelain damage and contain water spillage.

Preparing the Flange

Flange Maintenance: Clean off old wax, inspect for damage, and ensure it’s level with the floor.

Flange Adjustment: If the flange is too low, use flange extenders or extra-thick wax rings.

Damage Check: Replace the flange if it’s cracked or broken.

Choosing the Right Wax Ring

Wax Ring Types: Select between standard rings or reinforced rings with a plastic horn, based on your toilet’s specifications.

Size and Fit: Ensure the wax ring fits the toilet’s outlet and the flange’s opening.

Installing the Wax Ring

Installation Steps: Center the wax ring on the flange and press down lightly to affix.

Seal Integrity: Avoid distorting the wax ring during installation to maintain a proper seal.

Setting the Toilet

Toilet Placement: Align and lower the toilet onto the flange, ensuring the bolts pass through the base.

Securing the Toilet: Tighten the bolts gradually, alternating sides to keep the pressure even.

Preventing Seal Damage: Avoid excessive movement once the toilet is set.

Final Steps

Water Connection: Reattach the water supply and turn it on slowly, checking for leaks.

Leak Testing: Flush multiple times to test the integrity of the installation.

Cleanup: Dispose of the old wax ring and materials, and tidy up the area.

Troubleshooting Common Issues

Leak Solutions: Tighten bolts or reposition the toilet for leaks at the base.

Adjusting for Rocking: Shim the toilet base if it’s unstable, and ensure it’s level.


Proper installation and regular maintenance of the wax ring are crucial for a functional and hygienic toilet. Regular inspections for leaks can prolong the wax ring’s life.
