With the flange securely installed, prepare for the toilet placement. Insert the new T-bolts into the flange slots, facing them upwards. Place a new wax ring directly onto the flange, centering it perfectly over the drain opening. This will create the final seal between the toilet and the flange.

FAQs
Is replacing a toilet flange truly a 'beginner' DIY project, and can it realistically be done in 4 hours?
While categorized as beginner, this project requires careful attention to detail, especially during toilet removal and flange installation. The 4-hour estimate is achievable for someone with basic DIY experience, but unexpected issues like rusted bolts or subfloor damage can significantly extend the time. Always plan for potential delays and have extra materials on hand.
Do I need specialized tools beyond the screwdriver, level, adjustable wrench, and putty knife listed in the guide?
For removing old flanges, you might need additional tools. A hacksaw, oscillating multi-tool, or grinder can be essential for cutting stubborn plastic or metal flanges. If dealing with a severely corroded cast iron flange, a cold chisel and hammer might be required. A wet-dry vacuum is also very helpful for cleaning debris from the drainpipe.
What should I do if I discover significant subfloor damage around the old flange after removal?
Significant subfloor damage must be repaired before installing the new flange to ensure a stable and leak-proof seal. Carefully cut out the damaged section and replace it with new plywood or cement board, ensuring it is level with the surrounding floor. Improperly repaired subfloor can lead to rocking toilets and future leaks.
How can I ensure a leak-proof seal when installing the new toilet flange?
First, make sure the subfloor surface where the flange sits is clean, dry, and level. Dry-fit the flange to confirm it sits flush with the finished floor. Secure it with the appropriate #10 3” wood screws, but be careful not to overtighten and crack the flange. The proper wax ring (or waxless seal) will then create the final watertight connection with the toilet.
