How to Remove an Old Toilet

Before installing a new toilet, you need to remove the old one properly. This process can take you anywhere from 15 minutes to 30 minutes. Here are the steps you will need to follow: 

1.Drain the toilet 

The first step is to empty the cistern. You will need to flush the toilet to drain your cistern. Even after this, there might still be some water left. After lifting the lid, you can use the sponge or cloth to soak up the remains. 

     2.  Halt water supply 

You don’t need any water when replacing the toilet unit, so it’s best to disconnect the water supply at the very source for the time being. 

      3. Remove the cistern 

The cistern is the part that holds the water for flushing. It’s usually mounted on the wall behind the toilet bowl or hidden inside a wall behind it. You don’t need to worry about this step if your toilet system comes in one piece. 

Remove the lid of the cistern. It should come off unless it is a push-down flush system instead of a lever one. Then you need to remove the screws and bolts at the bottom of the cistern. If you have trouble removing the bolts due to rusty or worn-out, you can use a wrench or pliers.

    4. Unscrew the mounting nuts

The mounting nuts are what hold your toilet in place on the floor. These need to be removed. Use a screwdriver or a wrench to remove these nuts. You may need to add a bit of muscle here since these may be rusty due to being in place for a while. 

      5. Lift the toilet and remove the caulk 

Most toilets are attached to the floor using caulk or silicone. You can scrape this material off using a utility or a putty knife. Once done, use a cloth to clean up the toilet floor. 

Carefully lift your toilet without getting injured, as the unit can be pretty heavy. 

       6. Remove wax ring 

Your toilet is attached to the sewer line, so before you can completely lift it and put it aside, you will need to disconnect it from the sewer line. Use a utility or putty knife to cut through the old wax ring that connects the toilet to the sewer line. 

        7. Remove flange and bowl bolts 

The flange is what keeps your toilet unit stable on the floor. Once you can locate it, it’s time to unscrew it. This is the last step in removing your toilet. 

How to Fit a Toilet

Now that you’ve successfully removed the old toilet, it’s time to install your brand new toilet. Follow these steps: 

1.Install new wax ring and mounting bolts 

Keep your water supply turned off to avoid any mess. Take your new mounting bolts and screw them in the old holes on the floor. Now, install the new wax ring. Wear gloves because the wax ring substance is quite sticky. 

     2. Fit the unit 

Fix the unit by tightening the bolts with the nuts. Ensure that your bolts are fitted right and align with the new unit by hovering your toilet over the bolts. Your new toilet is now connected to the floor.  

    3. Install cistern 

Take the new cistern and attach it to the toilet using screwdrivers. This step doesn’t apply if you’re installing a one-piece system. 

   4. Turn on the water supply

You should now be ready to turn on the water supply but understand that there might be some leakage. 

     5. Check for leaks 

Ensure there are no leaks and drips by repeatedly flushing the toilet. You don’t want all that hard work to go to waste, so make sure that there isn’t water leaking onto the floor.

      2. When should you replace a toilet? 

You will need to replace a toilet after every 50 years. However, this time frame will depend on the condition of the toilet and how well it is taken care of. If the toilet wasn’t installed properly or wasn’t used the right way, it might need to be replaced sooner. 

       3. Are one-piece toilets better?

Your choice will depend on your needs. One-piece toilets are easier to install and have less chance of accumulating bacteria. If you need more customization in size and height, then two-piece toilets are a better option for you.
