toilet replace by Toronto PlumbersGet the tools you will need

To replace a toilet you will need just a few tools. You will need either an adjustable wrench or a standard wrench set with different sizes. You will also need a razor knife and some towels for cleanup.


The most obvious will be the toilet itself. The brand and model of toilet will depend on your taste and budget. However, when purchasing a toilet make sure to measure the distance between the mounting holes of the toilet tank and the wall. You will need to know the clearance you have; as many toilets have different size tanks. The other items you will need is a toilet bowl wax ring and toilet bowl mounting bolts. You may want to pick up a tube of silicone caulk as well.

Removing the Old Toilet

First shut off the water supply to the toilet by turning the shut off valve located at the back of the toilet on the wall. Now flush the toilet several times to remove as much water from the bowl as possible. Remove the lid of the toilet tank and open the flapper valve to drain as much water out of the tank as possible and flush again. Now use a small cup or large towels to soak up any remaining water in the tank.

Next you will need to disconnect the water supply line. Use a standard wrench or adjustable wrench. If the supply line nut is made of plastic then use a pair of channel locks. If you are removing the entire toilet then you will not need to take the tank off the toilet bowl unless you want to for convenience of carrying it out.

If you are removing the tank, than do so by taking the nuts off the tank bolts located under and back of the toilet tank. If the nuts turn the bolt then you may need a screw driver on the bolt from the inside while turning the nut from below to break them free.

To remove the toilet bowl start by using the razor knife to cut away any caulk that is around the bowl. Removing the caulk will ensure you do not damage the floor when pulling up the toilet bowl and will make it much easier to do so.

Now take the two toilet mounting bolts off. They are located under the caps on both sides of the toilet base. In some cases these bolts can be rusted to the nuts and will not break free. If this is something you come across then use a small hacksaw blade to cut the bolt under the nut.

Now you can remove the toilet by gently rocking it from side to side, to break the seal the wax ring has made. Once the toilet is free simply pull straight up and out.

Replacing the toilet

Prepare the area for the new toilet by cleaning the flange where the old wax ring was. Clean the floor of any debris and secure any loose flooring down. Set your new toilet mounting bolts in the slots provided on the floor flange. Tip the new toilet bowl on its side and gently press the new wax ring to make it stick to the toilet bowl.

Now carefully guide the toilet bowl over the mounting bolts in as straight downward motion as possible. Be careful not to damage the wax ring as you guide the toilet bowl in place. Now rock the toilet from side to side to set the wax ring in place and push the toilet bowl all the way down to meet the floor. Now place the nuts on the mounting bolts being careful to not over tighten as you can crack the porcelain very easily.

Mounting the Toilet Tank

Follow the instructions supplied by the manufacturer on what seals to use between the tank and bowl. Guide the tank over the mounting holes and set the tank down. Now run the mounting bolts with any washers the manufacturer has included through the tank and place the nuts on the bottom. Tighten the nuts carefully, getting them snug but not too tight.

Be careful not to over tighten to prevent cracking the porcelain.

Now connect the supply line back to the underneath of the toilet. Open the supply line shut off valve slowly and let the toilet tank fill. Check for leaks all around the toilet as you do this. Once the tank is full, flush the toilet to ensure the wax ring sealed correctly.

You should not see any water coming from under the bowl. If you do you may have damaged the wax ring when placing the bowl down or did not set it correctly. If everything is working correctly all you have to do is caulk around the toilet bowl, put the tank lid on and the mounting bolt covers for the bowl.

That’s all there is to it and now you can enjoy hours of sitting time on your new toilet.
