How To Install A Wax Ring On A Toilet

If you’re ready to tackle a DIY plumbing project, installing a wax ring on a toilet is a great place to start. A properly installed wax ring ensures a tight seal between the toilet and the floor, preventing leaks and odors. In this article, we’ll walk you through the steps of how to install a wax ring on a toilet.

Gather Your Tools and Supplies

Before you start, make sure you have all the necessary tools and supplies. You’ll need a wax ring, a new set of bolts, a putty knife, a pair of gloves, a wrench, and a bucket. You may also want to have some towels on hand in case of any spills.

Remove the Old Wax Ring

The first step in how to install a wax ring on a toilet is to remove the old wax ring. Turn off the water supply to the toilet and flush it to remove as much water as possible. Then, use a putty knife to scrape away the old wax ring from the base of the toilet and the flange.

Inspect the Flange

While you have the old wax ring removed, take a moment to inspect the flange. Make sure it is in good condition and securely attached to the floor. If it is damaged, you may need to replace it before proceeding with the installation.

Prepare the New Wax Ring

Take the new wax ring out of its packaging and allow it to warm up to room temperature. This will make it easier to work with. Then, gently shape the wax ring with your hands to fit it around the base of the toilet.

Install the New Wax Ring

Carefully lower the toilet onto the new wax ring, making sure to align the bolts with the holes in the flange. Use your body weight to press down on the toilet, compressing the wax ring and creating a tight seal.

Secure the Toilet

Once the toilet is in place, insert the new bolts and hand tighten them. Then, use a wrench to tighten them further, being careful not to over-tighten and crack the toilet. Finally, trim the excess bolt length with a hacksaw.

Reconnect the Water Supply

Reconnect the water supply to the toilet and turn it on. Check for any leaks around the base of the toilet. If you see any water, tighten the bolts a little more until the leak stops.

Clean Up

Clean up any excess wax or debris from the installation process. Wipe down the toilet and surrounding area with a disinfectant cleaner.


What if the toilet wobbles after installation?

If the toilet wobbles after installation, it may be because the flange is not level. You can use shims to level the flange and prevent the toilet from wobbling.

What if the wax ring doesn’t create a tight seal?

If the wax ring doesn’t create a tight seal, it may be because it is not the right size for your toilet or because it was not installed properly. Remove the toilet and start over with a new wax ring.

How often should I replace the wax ring?

It is recommended to replace the wax ring every time you remove the toilet for any reason. This ensures a tight seal and prevents leaks and odors.


Now that you know how to install a wax ring on a toilet, you can confidently tackle this DIY plumbing project. With the right tools and supplies, it’s a relatively simple task that can save you money on a professional plumber. Just remember to take your time and follow the steps carefully for a successful installation.
