How Wax Toilet Seal Works

A wax toilet seal is a ring made of sticky wax placed between the bottom of the toilet bowl and the opening of the sewer pipe. The weight of the toilet compresses the wax to form an airtight and watertight seal to prevent water and gas leakage from the toilet.

Manufacturers use varying ingredients to make the wax, including beeswax, petroleum, or other ingredients.

Installing a new toilet or replacing the wax ring is not difficult, but getting the heavy toilet in the correct position can be daunting. Expect to ruin several rings before getting it right.


  • They have been used for a long time; hence they are tried and tested for effectiveness.
  • Wax ring seals can adjust in shape to fit any toilet
  • The seal can last for many years
  • Offer better resistance to molds and bacteria


  • They start to leak over time
  • They are messy
  • Melt under heat hence not suitable for heated floors
  • They are not reusable

How Waxless Toilet Seals Works

Waxless toilet seals are made of rubber or foam in place of the wax. Waxless seals hold the toilet in place and prevent leakage using a strong adhesive. What’s more, they address all the problems of wax seals.

5 Instances When To Replace A Toilet Seal

Toilet seals can last for many years as long they are installed correctly. However, for various reasons, sometimes these seals do not work as expected, hence the need for replacement.

Below are signs that your toilet wax or waxless seal is not functioning as it should:

1. Water Pool Around The Toilet Base

A collection of water at the base of the toilet is an indication that the toilet seal is broken or leaking. Some water leaks out through the seal when you flush the toilet instead of going down the drain.

However, you should not be quick to replace the seal because sometimes the pool can result from a leaking tank or pipe. It is safe to consult with a plumber for the correct diagnosis.

2. Odors

Besides preventing water leakages, toilet seals are supposed to avoid the leakage of sewage odors. Therefore, if your bathroom is smelling like sewer or rotten eggs, it means that there is gas leaking out from the drain pipes.

The only way to get rid of the awful smell is to replace the seals immediately. What’s more, ensure that the toilet bowl has enough water and no clogs because the smell could also be coming from the toilet bowl.

3. Wobbly Toilet

If your toilet is rocking from side to side, the flange is highly likely to be broken. To make your toilet firm again, the flange must be replaced and, therefore, the seal.

Note that any time you move the toilet or the bowl, the integrity of the seal is compromised and must be replaced. Wax seals cannot be reused, so; you must purchase new ones.

On the other hand, waxless seals can be reused, but they must be in good condition.

4. Floor Replacement

If you are changing the bathroom’s flooring, it means that you will have to remove the toilet. As mentioned above, any time you move the toilet for whatever reason, the seals must be replaced.

5. Leakage From The Ceiling

If you ever notice leakage on the floor-ceiling below a toilet, there is a high possibility that the toilet is leaking. Sometimes the leaking water penetrates the floor, causing dampness or leakage on the ceiling below.

When you see a leakage on your ceiling, find out the water source immediately; otherwise, you might have to replace the whole ceiling. What’s more, the dampness makes the house very cold and leads to the growth of mold.

If the water is coming from the toilet, replace the seal as soon as the same today to avoid more damage.

How To Replace A Toilet Seal In 7 Steps

Toilet rings are available in most hardware stores, and you can do the replacement on your own. However, you must have average DIY skills for a successful toilet seal replacement.

In addition to the DIY skills, you should have the following tools:

  • A bucket
  • Knife
  • Heavy cloth rag
  • Gloves
  • Wrench
  • Hairdryer
  • Wet/dry shop vacuum

After gathering all the tools above, follow the simple steps below to replace the toilet seal:

1. Disconnect Water Supply

The first step to replacing a toilet is cutting off the water supply to the tank. Locate the valve on the pipe bringing in water to the toilet tank, and turn it off. If you have not moved the valve since installing the toilet, do not be surprised if it is sticky.

2. Drain The Toilet

Flushing the toilet is the easiest way to drain the tank, but all the water will not go away. To dry the tank completely, use the wet/dry vacuum cleaner or a heavy cloth rag to wipe it dry. What’s more, disconnect the pipe under the toilet tank to remove residue water. Catch the water with a bucket to avoid wetting the floor.

3. Remove The Toilet

Carefully remove the caps covering the bolts to access the bolts. Using the adjustable wrench remove the bolts and washers on the toilet’s base and store them safely in a container.

Rock and twist the toilet gently to crumble the old wax ring. Once it’s all loose, take a proper lifting posture and remove the toilet from its position. If it is too heavy for you, call for help or separate the tank and the bowl and move them separately.

4. Remove The Old Wax

To install a new seal, whether a wax or waxless ring, you must get rid of the old wax. For this step, put on your disposable gloves and use the putty knife to scratch away the wax from the flange and the bottom of the toilet.

If the wax is too sticky, use a hairdryer to melt it and use a cloth rag to wipe it away.

Check the flange for any damages or dents and in case of anything unusual, call a plumber for assessment. Also, you can cover the opening of the flange with a cloth to prevent the escape of foul smells from the drain as you get ready to replace the seal.

5. Place The New Ring

Before replacing the seal, ensure that it is the right size for the flange. Also, refer to the installation guide from the manufacturer. After you center the seal correctly, carefully and gently lower the toilet onto the flange.

The replacement is successful if the bolt holes on the toilet are directly aligned with the holes on the bathroom floor.

6. Close The Toilet And Sit

Your body weight will push the seal down and align the toilet correctly. By the end of this step, the toilet base should be lined up with the floor.

7. Replace The Bolts

The last step to keep the toilet in place is replacing the bolts and the covers. After that, replace the water supply lines and open the valve. Before cleaning up the area, flush the toilet severally to ensure that there are no leaks.
