  • Wrench – it is used to unfasten the old bolts of the toilet around the flange
  • Multi-head screwdriver – it is used to loosen the screws and remove the toilet

2. Flush and Empty the Toilet

Turn off the knob to stop the water supply to the water tank. Flush the water tank until it gets empty. Disconnect the water supply hose from the toilet. Keep a big tub/vessel to collect the leaking water, if any.

3. Remove the Toilet

Cover the bathroom with old newspapers. Use a wrench to remove the bolts that hold the toilet down. Now with the help of someone, lift the toilet and place it away from the work area and keep it in the newspaper, so the area doesn’t get spoiled.

4. Block the Outflow Pipe with a Rag

Once the toilet is removed, immediately stuff the old cloth rag in the outflow pipe to prevent an awful odor. Do not stuff much inside that it becomes difficult to pull it outside again.

Remove the rag stuff in the outflow pipe. Now place the wax ring on a clean surface. Insert screws and put the new flange on it. Now with the help of someone, place the toilet on the replaced flange and apply pressure to set the seal. Make sure the toilet is placed straight at once, as it cannot be moved once placed on a wax ring. Tighten up the replaced toilet flange with bolts (use new bolts if old ones are worn out).

7. Reconnect the Water Supply

Reconnect the Water Supply

Reconnect the water supply hose and start the water supply. The tank will begin filling, meanwhile, examine if there is any leakage of water between the toilet tank and supply line. Flush the water several times to check if there is no leakage. If the floor is dry, then you have succeeded in replacing the toilet flange. But if there is a leakage, then you will have to install it again or call a plumber to do the same.

Above were the steps to install or replace a toilet flange, which is detachable and also simple to install.

Now let’s discuss the Toilet flange extender 

A toilet flange extender fits over the existing flange to raise the drain connection to the surrounding flooring. Plastic flanges typically cannot be removed because they’re the glue to the drain pipe. So in such cases, we’d like to use toilet flange extenders, which are made from plastic rings that are available in various thicknesses. Most extenders are secure by fastening them to the subfloor with screws driven through the holes within the old flange.

The materials required for installing a toilet flange extender are the same as that of a regular toilet flange. The only additional piece of equipment needed is silicone caulk. Sometimes toilet flange extenders have rubber gaskets that will not require caulk for sealing the space between the floor and the extender.

Now while installing the toilet flange extender, the procedure remains the same as that of replacing the toilet flange. One minor change is that as the flange is the glue to the drainpipe, the extender is to be applied above the existing one. Apply a liberal amount of silicone caulk on the bottom of the flange extender. Place the extender on the top of the old flange, including spacers as required. Place the screw holes in the extender into the old extender. Tighten up the screws to the extender with the floor.

Since the extenders are not replaceable, one needs to check the durability of them.

What kind of toilet flange extenders should one buy that will last for a longer time?

An extender that has a stainless steel ring will last longer than that of plastic material as they are more prone to damage. It is essential to buy superior quality flange material because the toilet being the moist area is in constant contact with the toilet waste, which makes it more prone to damage.

How often should one change the Toilet Flange?

A wax seal material is used between the toilet, and the flange helps to retain the water from leaking as it passes from the toilet to the sewage pipe. It also seals the awful odors. A wax seal will often last up to 20 to 30 years without needing to be changed.


To conclude the above, there are two methods to replace toilet flange extenders, which are easy to install if done correctly. If you feel that you are not comfortable with doing this work, then a plumber is always there to fix the problem.
