Tools and Materials

Before you begin installing a new toilet in your bathroom, make sure you have all the necessary tools and materials. Here’s a list of what you’ll need:


  • Adjustable wrench
  • Screwdriver (Phillips or flathead, depending on your toilet)
  • Putty knife
  • Hacksaw
  • Level
  • Tape measure


  • New toilet
  • Wax ring
  • Closet bolts
  • Toilet seat
  • Caulk

Preparing for Installation

Before you start the installation process, there are a few essential steps you should take to ensure a smooth and successful installation.

1. Measure the space

Start by measuring the space where your new toilet will go. Measure the distance from the wall to the center of the bolts that hold the toilet to the floor. Make sure these measurements match the requirements of the toilet you have purchased.

2. Remove the old toilet

If you already have a toilet in place, you’ll need to remove it before installing the new one. Start by turning off the water supply to the toilet and flushing to remove any water from the tank. Disconnect the water supply line and loosen the nuts that hold the toilet in place. Carefully lift the toilet and set it aside.

3. Clean the area

Once the old toilet is removed, take the time to thoroughly clean the area where the new toilet will go. Remove any old wax or debris from the flange and floor. This will ensure a proper seal and prevent any leaking.

4. Check the plumbing

Before installing the new toilet, it’s crucial to check the condition of your plumbing. Inspect the flange to ensure it is in good condition and securely attached to the floor. If there are any issues, it’s best to address them before proceeding with the installation.

Installing the New Toilet

Now that you’ve completed the necessary preparations, it’s time to install your new toilet. Follow these steps to ensure a successful installation.

1. Assemble the toilet

Begin by assembling your new toilet according to the manufacturer’s instructions. This typically involves attaching the tank to the bowl and connecting the necessary hardware.

2. Install the wax ring

Place the wax ring onto the flange, ensuring it is centered and properly aligned with the bolts. The wax ring creates a watertight seal between the toilet and the flange, preventing any leaks.

3. Position the toilet

Carefully lower the toilet bowl onto the wax ring, aligning it with the bolts on the flange. Apply gentle pressure to compress the wax ring and create a secure seal. Make sure the toilet is centered and level.

4. Secure the toilet

Once the toilet is properly positioned, secure it to the floor by tightening the nuts onto the closet bolts. Be careful not to overtighten, as this could crack the porcelain. Use a level to ensure that the toilet is perfectly balanced.

5. Connect the water supply

Attach the water supply line to the fill valve on the underside of the tank. Use an adjustable wrench to tighten the connection. Make sure the water supply valve is open.

6. Test for leaks

Once everything is securely connected, turn on the water supply and allow the tank to fill. Check for any leaks around the base of the toilet and around the water supply connection. If you notice any leaks, tighten the connections or replace any faulty parts.


Sometimes, even with careful installation, issues may arise. Here are a few common problems and how to address them.

1. Leaky connections

If you notice any leaks around the water supply line or the base of the toilet, try tightening the connections. If this doesn’t solve the issue, you may need to replace the wax ring or faulty parts.

2. Uneven toilet

If your toilet isn’t sitting level on the floor, it can cause discomfort and potentially lead to leaks. Use a level to check the toilet’s balance and adjust the closet bolts accordingly.

3. Toilet rocking

If your toilet is rocking back and forth, it may not be securely fastened to the floor. Tighten the nuts on the closet bolts until the toilet is stable. If the floor beneath the toilet is uneven, you may need to use shims to create a level surface.

4. Fixing a wobbly toilet

If you have a wobbly toilet, it’s best to start by inspecting the toilet bolts. If they are loose or damaged, tighten or replace them as needed. You can also use shims to stabilize the toilet and prevent it from rocking.

Finishing Touches

After successfully installing your new toilet, there are a few finishing touches you can add to enhance its appearance and functionality.

1. Trim the bolts

If the closet bolts are too long, you can trim them using a hacksaw. Be sure to leave enough bolt protruding to secure the toilet, but not so much that it’s visible or interferes with the wax ring.

2. Attach the toilet seat

Most toilets do not come with a seat included, so you’ll need to purchase one separately. Follow the manufacturer’s instructions to attach the toilet seat securely.

3. Caulk the base

To create a clean and finished look, consider applying a bead of caulk around the base of the toilet where it meets the floor. This will provide a watertight seal and prevent any debris from collecting in the gap.
