Tools You’ll Need
- New wax ring or wax-free seal
- Adjustable wrench
- Putty knife
- New toilet bolts (recommended)
- Work gloves
- Bucket and towels
Step 1: Remove the Old Toilet
Turn off the water supply valve behind the toilet. Flush to empty the tank. Disconnect the water supply line. Remove the bolt caps and unscrew the nuts securing the toilet to the flange. Rock the toilet gently to break the seal, then lift straight up. Place it on old towels.
Step 2: Clean the Flange
Scrape away all old wax residue from the flange using a putty knife. Inspect the flange for cracks or damage. If the flange is broken, install a repair ring before proceeding. The flange should sit flush with or slightly above the finished floor level.
Step 3: Install New Bolts
Insert new closet bolts into the flange slots. Use the plastic washers to hold them upright. These bolts will secure the toilet to the floor.
Step 4: Apply the New Seal
For wax rings: Place the wax ring centered on the flange, plastic horn facing down if included. Press firmly to adhere.
For wax-free seals: Position the rubber seal on the flange according to manufacturer instructions. Ensure it sits flat and centered.
Step 5: Set the Toilet
Lift the toilet and align the bowl holes with the closet bolts. Lower straight down — do not twist or slide. Let the toilet’s weight compress the seal. Press down firmly around the base.
Step 6: Secure and Connect
Place washers and nuts on the bolts. Tighten evenly, alternating sides. Do not overtighten — this can crack the porcelain. Trim excess bolt length and snap on caps. Reconnect the water supply and turn on the valve. Test flush several times and check for leaks.
Pro Tips
- If the flange is below floor level, use an extra-thick wax ring or flange extender
- Never reuse an old wax ring — always install a new one
- Replace supply line and bolts for best results
- If you smell sewer gas, the seal may not be seated correctly
