Tools and Materials Needed to Change a Toilet

Before getting started, gather these essential items:

• Drop cloth or plywood
• Gloves
• Mini hacksaw
• New toilet
• New wax ring
• Open-ended adjustable wrench
• Plumber’s tape
• Putty knife
• Replacement closet bolts
• Sponge and bucket

How to Remove and Replace a Toilet

Step 1: Shut Off the Water Supply

Locate the shutoff valve (usually behind or beside the toilet) and turn it clockwise until the water flow stops.

Step 2: Drain the Toilet

Flush the toilet to empty the tank and bowl. Remove any remaining water with a sponge and bucket or a turkey baster.

Step 3: Disconnect the Water Supply Line

Loosen the nut connecting the supply line to the tank using your hands or an adjustable wrench. Place a container underneath to catch any drips.

Step 4: Remove the Toilet

Pop off the decorative caps covering the closet bolts. Use a wrench to remove the nuts and washers. Gently rock the toilet back and forth to break the wax seal. Lift the toilet straight up and place it on a drop cloth or plywood.

Step 5: Clean the Flange Area

Scrape away any old wax or debris from the flange with a putty knife to ensure a clean surface for your new toilet.

How to Install the New Toilet

Step 1: Inspect and Prepare the Flange

Check that the flange is undamaged and securely attached to the floor. If necessary, replace it before proceeding.

Step 2: Set the New Closet Bolts

Insert new closet bolts into the flange. Using bolts with plastic tabs makes positioning easier.

Step 3: Apply the Wax Ring

Place the new wax ring on the flange, centering it carefully.

Step 4: Position the New Toilet

Lower the new toilet over the closet bolts and onto the wax ring. Press down evenly using your body weight to create a watertight seal. Avoid rocking or twisting the toilet.

Step 5: Secure the Toilet

Add washers and nuts to the closet bolts, tightening evenly to prevent cracking. Use a hacksaw to trim any excess bolt length, then replace the decorative caps.

Reconnect the Water Supply

• Wrap plumber’s tape around the fill valve threads.
• Reattach the water supply line, tightening by hand first, then with a wrench.
• Slowly turn the shutoff valve back on and allow the tank to fill.
• Check for leaks around the base and supply line connection.
• Flush several times to ensure proper function.

Finishing Touches

Install the Toilet Seat

Follow the manufacturer’s instructions to secure the new seat.

Caulk the Base

Apply silicone caulk around the toilet base for a cleaner look and to prevent water seepage.

Final Flush Test

Flush the toilet several times to verify performance and check for leaks.

Common Issues and Fixes

• Leaks: Re-seat the wax ring or use two rings for a better seal.
• Rocking toilet: Level it with shims before caulking.
• Weak flush: Check the fill valve and flapper.
