Did you know the average leaky toilet can waste tens of thousands of gallons of water each year?! That’s not only terrible for the environment but for your wallet too. Keeping your toilet in good repair is one of the smartest moves you can make as a homeowner.

So, in honor of National Toilet Repair Month (yes, it’s a thing!), we’ve put together this blog to help you with one task that will show up in many different toilet repair projects: replacing the wax ring.

Whenever replacing a toilet wax ring, it’s essential to make sure you get the appropriate size for your toilet. If you don’t and try to install a new toilet or put back your old one, you’ll have to buy a brand new ring and start all over!

So, to help you get this job done right the first time here is a quick guide on how to determine the correct wax ring size for your toilet.

How to Determine the Wax Ring Size for a Toilet

There are only two factors to a correctly sized wax ring: width and thickness.

1. Width – Measure the bottom of your toilet.

To determine the correct width for your wax ring, simply turn your toilet bowl on its side, and measure the opening on the bottom of your toilet, called the “elbow neck.”

Whatever width this measurement is, use that width wax ring. E.g. if the elbow neck measures 3 inches, use a 3-inch wax ring.

Alternate option: You can also measure the old wax ring to determine the width – though we recommend also measuring the bottom of your toilet, in case the last person who installed your toilet used an incorrectly sized wax ring.

2. Thickness – Check the toilet flange.

Lucky for you, there are only two thickness options to choose from: regular and double-thick.

To determine which one is right for you, you’ll need to check the “toilet flange” – a metal or plastic piece that can be found over the pipe in the floor under your toilet.

If the flange is level with your floor, a regular-thickness wax ring will be fine. You’ll only use a double-thickness wax ring if the flange is located under the floor.
