Tile Over Toilet Flange Mistake? Don’t Panic! Here’s How to Fix It

Tiling a bathroom floor can be a significant home improvement project, but what happens if you realize after the fact that your toilet flange is too low? Don’t panic! Raising a toilet flange after tiling is possible with the right tools and techniques. This comprehensive guide will walk you through the steps involved in this adjustment, ensuring a secure and functional bathroom fixture.

Step 1: Gather Your Tools

Before you begin, gather the following materials:

• Adjustable wrench
• Hacksaw
• Utility knife
• Toilet flange extender
• Shims (optional)
• Plumber’s putty
• Wax ring

Step 2: Remove the Toilet

Start by turning off the water supply to the toilet and flushing to empty the tank. Disconnect the water supply line and unbolt the toilet from the floor. Carefully lift the toilet and set it aside.

Step 3: Cut the Old Flange

Use a hacksaw to cut through the old flange at the base of the drainpipe. Be careful not to damage the pipe itself. If the flange is made of plastic, you can use a utility knife instead.

Step 4: Install the Flange Extender

Place the flange extender over the drainpipe and secure it with the bolts provided. Tighten the bolts firmly using an adjustable wrench.

Step 5: Add Shims (Optional)

If necessary, use shims to ensure the flange is level and at the appropriate height. Place the shims between the flange extender and the floor, adjusting as needed.

Step 6: Apply Plumber’s Putty

Apply a generous amount of plumber’s putty around the base of the flange extender. This will help create a watertight seal between the flange and the floor.

Step 7: Install the Toilet

Place the toilet back on the floor, aligning the bolts with the holes in the flange. Tighten the bolts securely, but avoid overtightening.

Step 8: Install the Wax Ring

Place the wax ring on the flange, ensuring it is centered and properly seated.

Step 9: Reconnect the Water Supply

Reconnect the water supply line to the toilet and turn the water back on. Flush the toilet to test for leaks.

Seal the Gaps

Use caulk or silicone sealant to fill any gaps between the toilet base and the floor. This will prevent water from seeping into the subfloor.

Troubleshooting Tips

• If the flange is too high, you can remove the toilet and cut off a portion of the flange extender.
• If the flange is not level, adjust the shims accordingly.
• If you encounter any leaks, tighten the bolts or apply additional plumber’s putty.
