Are you tired of dealing with a leaky or loose toilet flange? This essential component connects your toilet to the drainpipe below, ensuring a secure seal and proper waste disposal. If the flange becomes damaged or misaligned, it can lead to a host of unpleasant plumbing issues. Fortunately, replacing a toilet flange is a relatively straightforward task that can be tackled with the right tools and a bit of DIY know-how. Follow these step-by-step instructions to learn how to remove an old toilet flange and install a new one, ensuring a leak-free and fully functional toilet.
Before embarking on the removal process, it’s crucial to gather the necessary tools and materials. You will need a hacksaw, a utility knife, a flathead screwdriver, a hammer, a chisel, a new toilet flange, and some plumber’s putty. Once you have everything you need, you can turn off the water supply to your toilet and flush the remaining water to empty the tank and bowl.
With the water supply turned off and the toilet bowl empty, you can begin removing the old flange. Start by using a hacksaw to carefully cut through the old flange bolts. Be sure to make the cuts as close to the floor as possible to avoid damaging the subfloor. Then, use a utility knife to remove the old wax ring and any remaining putty from the flange.
Identifying the Toilet Flange
The toilet flange is a circular metal or plastic ring that is secured to the floor of the bathroom and serves as the base for the toilet. It is essential for providing a stable and secure connection between the toilet and the drainpipe. To remove the toilet flange, you must first identify it. Here’s how:
1. Locate the Toilet Base
Begin by removing the toilet seat and lid. Locate the base of the toilet, which is the part that rests on the floor.
2. Inspect the Floor Around the Toilet
Examine the floor around the toilet base closely. The toilet flange will be visible as a circular metal or plastic ring that surrounds the base of the toilet. It may be flush with the floor or slightly raised above it. The flange will have several bolt holes around its circumference, which are used to secure the toilet to the floor.
3. Measure the Flange
To confirm that you have identified the toilet flange, measure its diameter. The standard toilet flange is 4 inches (10.2 cm) in diameter. However, there may be variations, so measuring the flange is important.
| Type of Flange | Diameter |
|---|---|
| Standard Toilet Flange | 4 inches (10.2 cm) |
| Large Toilet Flange | 4 1/2 inches (11.4 cm) |
| Small Toilet Flange | 3 1/2 inches (8.9 cm) |
Once you have identified the toilet flange, you can proceed with the removal process.
Breaking the Seal
Once you’ve removed the toilet bowl, you’ll need to break the seal between the flange and the floor. This can be done with a variety of tools, including a putty knife, a utility knife, or a reciprocating saw.
Using a Putty Knife
If the seal is made of soft material, such as wax or putty, you can use a putty knife to cut through it. Insert the putty knife between the flange and the floor and gently pry upwards. Be careful not to damage the flange or the floor.
Using a Utility Knife
If the seal is made of a harder material, such as silicone, you can use a utility knife to cut through it. Score the seal with the utility knife, then use a putty knife or a small chisel to pry it away from the flange.
Using a Reciprocating Saw
If the seal is particularly thick or tough, you can use a reciprocating saw to cut through it. Use a blade that is designed for cutting metal or plastic. Be careful not to damage the flange or the floor.
Once you’ve broken the seal, you can remove the flange from the floor. If the flange is bolted down, you’ll need to remove the bolts before you can remove the flange.

Removing the Flange
To remove the toilet flange, follow these steps:
1. Turn Off Water Supply
Turn off the water supply to the toilet by turning the valve located behind the toilet. Flush the toilet to remove any remaining water from the tank and bowl.
2. Disconnect Supply Line
Disconnect the water supply line from the fill valve at the bottom of the tank. Use an adjustable wrench to loosen the nuts connecting the line to the valve.
3. Remove Tank and Bowl
Remove the nuts securing the tank to the bowl using a wrench. Carefully lift the tank off the bowl and set it aside. Then, remove the nuts securing the bowl to the floor and lift the bowl out of the way.
4. Remove Flange Bolts
Locate the four flange bolts that secure the flange to the floor. Use an adjustable wrench or socket wrench to loosen and remove the bolts.
5. Pry Up Flange
Use ać’¬bar or flathead screwdriver to gently pry the flange up from the floor. Be careful not to damage the flange or the floor.
6. Remove Wax Ring and Clean Surface
Once the flange is loose, remove the old wax ring from the bottom of the flange. Use a putty knife or razor blade to scrape away any remaining wax or debris from the flange and the floor surface.
Thoroughly clean the flange and the floor surface with a degreasing cleaner to remove any dirt, oil, or other contaminants.
Allow the surface to dry completely before installing a new flange.

Installing a New Flange
8. Install the Flange and Bolts:
a) Apply a thin bead of sealant around the bottom of the flange. This will help to prevent leaks.
b) Carefully place the flange over the drainpipe, aligning the bolt holes.
c) Insert the bolts into the holes and hand-tighten them as much as possible.
d) Use a wrench to further tighten the bolts, but do not overtighten them. Overtightening can damage the flange or the drainpipe.
9. Secure the Flange:
a) If the flange has a metal ring, use a screwdriver to tighten the screws that hold the ring in place. This will help to secure the flange and prevent it from moving.
b) If the toilet is installed on a wooden floor, use wood screws to secure the flange to the subfloor. This will help to prevent the flange from shifting or moving.
10. Install the Toilet:
a) Carefully lift the toilet onto the flange, aligning the bolt holes.
b) Insert the bolts into the holes and hand-tighten them as much as possible.
c) Use a wrench to further tighten the bolts, but do not overtighten them. Overtightening can damage the toilet or the flange.
d) Check to make sure that the toilet is stable and not rocking.
Reconnecting Water Supply
Once you’ve installed the new toilet flange, it’s time to reconnect the water supply. Here are the steps:
- Turn off the water supply to the toilet.
- Disconnect the old water supply line from the toilet.
- Connect the new water supply line to the toilet.
- Tighten the nuts on the water supply line.
- Turn on the water supply to the toilet.
- Check for leaks.
- Adjust the water level in the toilet, if necessary.
- Flush the toilet to make sure it’s working properly.
- Put the toilet seat and lid back on.
| Tools You’ll Need | Materials You’ll Need |
|---|---|
| Adjustable wrench | New water supply line |
| Plumber’s putty | Toilet flange |
| Screwdriver | Toilet wax ring |
| Tape measure | New toilet |
Testing for Leaks
After installing the new toilet flange, it’s crucial to test for leaks to ensure a watertight seal between the flange and the toilet. Here’s how:
- Gather materials: You’ll need a bucket, a flashlight, and some tissue paper or a small mirror.
- Remove the toilet: Unbolt the toilet from the flange and lift it off.
- Inspect the flange: Check the flange for any damage or cracks that could cause leaks.
- Place the tissue: Wet some tissue paper or hold a small mirror under the flange.
- Turn on the water: Turn on the water supply to the toilet.
- Monitor for leaks: Observe the tissue paper or mirror for water droplets.
- Check the floor: Inspect the floor around the flange for any water pooling.
- If no leaks: If no leaks are observed, the flange is properly sealed and you can proceed with installing the toilet.
- If leaks: If leaks are detected, tighten the flange bolts or apply a sealant around the base of the flange.
- Thorough inspection: For a more thorough inspection, use a flashlight to illuminate the underside of the flange and check for any imperfections or signs of water penetration. If leaks persist despite tightening or sealing, additional measures such as replacing the flange or adding a secondary seal may be necessary.
