How to Replace a Toilet Wax Ring – Step-by-Step DIY Guide

Written By Esteban .

Introduction

We know a leaking or wobbly toilet can cause frustration—and costly water damage if ignored. One of the most common causes? A worn-out wax ring. This small but mighty seal keeps water and sewer gas from leaking at the base of your toilet. Replacing it is a quick DIY fix or an affordable professional service we provide across the Chicago area.

Windy City Home Repair shows you how to replace a toilet wax ring like a pro. Follow our step-by-step guide to stop leaks, eliminate odors, and secure your toilet.

Why Do Wax Rings Fail?

Wax rings typically fail because of:

  • Loose toilet bolts

  • Floor movement or settling

  • Age and wear

  • Improper installation

Signs You Need a Wax Ring Replacement

  • Water pooling around the toilet base

  • Unpleasant sewer odors

  • Toilet rocking or wobbling

  • Persistent leaks after flushing

What You’ll Need

  • Adjustable wrench

  • New wax ring (standard or flange type)

  • Putty knife

  • Rubber gloves

  • Sponge/towels

  • Disinfectant cleaner

  • Bucket

  • Optional: New closet bolts

Step-by-Step Guide to Replacing a Wax Ring

1. Shut Off Water & Drain

Turn the shut-off valve clockwise, flush the toilet, and remove any leftover water using a vacuum or sponge.

2. Disconnect and Lift Toilet

Unscrew water line and bolts, then gently rock and lift the toilet straight.

3. Remove Old Wax Ring

Scrape away all wax residue from both the toilet and flange.

4. Install New Wax Ring

Set it evenly on the flange or toilet horn per package instructions.

5. Reinstall Toilet

Align bolts, lower toilet straight down, and press firmly to seal.

6. Tighten & Reconnect

Tighten bolts evenly (not too tight), reconnect water line, and turn water back on.

7. Test for Leaks

Flush several times while inspecting for leaks.
