When removing a toilet, replacing the wax ring between the bathroom and the floor-mounted toilet flange (commonly referred to as a closet flange) is essential. The wax ring’s purpose is to create a water and air-tight seal that can withstand years of use.

This blog will provide a step-by-step guide on replacing a toilet wax ring and offer tips to ensure your project is executed correctly.

We want to remind you that while DIYing is admirable, some jobs require a licensed professional. Always be honest about your skill level and call for help when needed.

What to Consider Before Replacing a Toilet Wax Ring

  • New Flooring: If you plan to replace vinyl flooring with something thicker, such as ceramic tile, this can create a gap between the toilet and the toilet flange. We recommend using a flange spacer to raise the flange to the proper height. Toilet flanges should sit on top of the finished floor.
  • Check Your Toilet Flange: Does your toilet wobble from side to side? If your toilet rocks enough for one side of the base to lift off the floor — even just a bit — you may have a broken toilet flange. As a precaution, we recommend picking up a flange repair kit.
  • Test Your Toilet’s Flapper: Fixing a leaky flapper can save hundreds of gallons of water. A good time to replace a leaky flapper is after you’ve drained the toilet tank and disconnected the water supply. To test the flapper before turning off the water, tint it in the tank with food coloring and let it sit for 10 minutes. If any colored water leaks into the bowl, replace the flapper.
  • Check For Water Damage: If you are removing the toilet because of a leak at the base or water damage in the ceiling below, confirm the cause of the damage before heading to the store. Water can damage the subfloor enough to affect the strength of the fasteners attaching the toilet flange — and the toilet — to the floor. Determine whether you need to cut away the damaged subfloor and replace it.
  • Inspect T-bolts: Anytime a wax seal is replaced, you should replace the T-bolts that attach the toilet to the flange. Some toilet wax rings come in a complete kit with new mounting bolts.
