How to Replace a Broken Toilet Flange · Step 3 of 6
In this video
Ensure the floor and the bottom of the pan are clean and free of dust and debris. Apply a polyurethane sealant, such as XtraBond 9500, to the underside of the pan in the channels and in a wavy pattern across the flat surface. Also apply a bead around the drain fitting. Now, apply PVC cement to the inside of the installed drain fitting and the outside of the floor pipe. Carefully lower the pan into position, aligning it with your floor marks and the drain pipe. Step into the pan and wiggle it to spread the sealant and ensure a strong bond with the subfloor.
Goal: Adhere the washer pan to the subfloor and connect the drain

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.
