How to Replace a Broken Toilet Flange · Step 5 of 6
In this video
Once the flange is at the correct height, install a new wax ring. Place the wax ring directly on top of the new flange, centered over the drain opening. Carefully lift the toilet, align the holes in its base with the new closet bolts sticking up from the flange, and lower it straight down. Press down firmly to compress the wax ring and create a seal. Place the washers and nuts on the closet bolts and tighten them down evenly, alternating from side to side. Be careful not to overtighten, as this can crack the porcelain base of the toilet. Reconnect the water supply, turn the water on, and check for leaks.
Goal: Toilet Repair
- If the flange is below the floor level, you might need to use two wax rings, but never use three. The proper fix is to raise the flange.
- Tighten the closet bolts gradually and evenly. The toilet should be snug and not rock, but overtightening will crack the base.

FAQs
Is this "intermediate" project doable for a DIY beginner, and is the 6-hour estimated time realistic?
While rated intermediate, a patient beginner can tackle this project by carefully following each step. The 6-hour estimate is achievable if the old flange removes easily and no extensive subfloor repairs are needed, but it's wise to plan for potential delays, especially for a first-timer.
Besides the listed items, are there any other crucial tools or materials I should have on hand for this toilet flange replacement?
Absolutely. Ensure you have buckets and old towels to catch residual water from the toilet, and a shop vac can be invaluable for cleaning up debris and standing water. Depending on your old flange, a hacksaw or oscillating tool might also be useful for its removal, and a level is essential for ensuring the new flange is properly set.
Why is "Subfloor Assessment and Preparation" listed as a key step, and what specifically should I look for?
Inspecting the subfloor around the drain is critical to ensure a stable, level base for the new flange and toilet. Look for any signs of water damage, rot, or weakness in the wood. If the subfloor is compromised, it must be repaired or replaced before installing the new flange to prevent future leaks and ensure the toilet sits securely.
What is the most critical step to ensure a watertight seal and prevent future leaks after replacing the flange?
Proper installation of the new wax ring and ensuring the new flange is securely mounted at the correct height relative to the finished floor are paramount. Ensure the PVC primer and cement are applied generously and allowed adequate cure time for a strong bond. When setting the toilet, press down firmly and tighten the toilet bolts evenly without overtightening to avoid cracking the bowl.
