Basic Tools Required

In addition to the tools, consider stocking up on essential plumbing supplies to avoid any mid-project trips to the hardware store:
- Wax ring: This is crucial for sealing the base of the toilet to the flange.
- Toilet bolts: These provide stability to the toilet during use.
- Flexible supply line: To connect the toilet to your water supply.

With your tools and supplies gathered, you are ready to move on to the next steps of the toilet removal process, making sure all is in order for the installation of your new toilet.
Step-by-Step Process for Removing the Old Toilet
Now that you are equipped with all the necessary tools, it's time to focus on removing your old toilet. This step is critical for ensuring a smooth transition to your new toilet. Follow this step-by-step guide to safely remove the old unit.
Disconnecting the Water Supply
First, turn off the water supply valve located near the toilet. Flush the toilet to drain the tank. If any water remains in the bowl, use your sponge or rag to soak it up. This minimizes spills during the removal process.
Removing the Toilet Tank
Next, unscrew the bolts securing the tank to the bowl using your wrench and screwdriver. Carefully lift the tank off and set it aside. This action lightens the entire assembly, making it easier to handle.
Detaching the Toilet Bowl
With the tank removed, it’s time to detach the bowl. Unscrew the toilet bolts holding it to the floor. Gently rock the bowl back and forth to break the wax seal and lift it off the flange. Be prepared for some residual water. Dispose of the old wax ring properly to maintain hygiene.
Inspecting the Flange and Plumbing
Before installing your new toilet, inspect the flange for damage. If the flange is cracked or broken, it may require replacement. You may also want to check the supply line and other fittings to ensure they are in good condition.
This brings us to the next crucial stage: installing your new toilet!

Installing Your New Toilet: Essential Steps
With the old toilet removed, we now turn to the exciting part – installing your new toilet. This section will guide you through each step, ensuring proper alignment and function.
Preparing the Site for Installation
Before placing your new toilet, ensure the flange is clean and the surface is level. If the flange is lower than the finished floor, you might need to use a flange extender. If not, proceed with applying a new wax ring on the flange.
Positioning the New Toilet
Carefully lift and position the new toilet over the wax ring and onto the flange. Make sure it is centered. Press down to compress the wax ring and secure it in place.
Securing the Toilet Bowl
Insert the bolts through the holes in the base of the toilet, securing it to the flange. Tighten the nuts gradually, ensuring the toilet remains level. Avoid overtightening, which could crack the porcelain.
Connecting the Tank
Next, attach the tank to the bowl if they are separate. Align the tank with the bowl and secure it with the provided hardware. Don’t forget to connect the flushing mechanism to ensure everything functions properly.
Connecting the Water Supply
Finally, attach the flexible supply line from your wall to the new tank. Turn on the water supply valve and let the tank fill. Check for leaks and make corrections as needed.
Final Touches and Maintenance Tips
Completing the installation involves some final touches, including checking the alignment and ensuring it's functioning correctly. Let's look at some essential finishing steps and ongoing maintenance tips.
Sealing the Base
Apply a bead of caulk around the base of the toilet to seal it against moisture. This not only improves aesthetics but also prevents potential water damage to your flooring.
Cleaning and Testing the Toilet
After assembly, it’s essential to clean the area and test the toilet. Flush a few times to ensure everything is functioning well without leaks. Make any necessary adjustments to the water level inside the tank to meet your preferences, keeping in mind the height of the toilet.
Regular Maintenance Tips
To maintain your toilet efficiently:
- Regularly check the flushing mechanism and supply lines for signs of wear.
- Consider scheduling a maintenance check annually to prevent common toilet issues.
- Be aware of any signs of leaks or flushing problems that may arise.
