How to Install a Toilet Flange Extender After Tiling · Step 6 of 6
In this video
Begin by applying a generous bead of 100% silicone caulk around the top surface of the existing, low-set toilet flange. To achieve a thick bead, which is necessary for a good seal, lift the tip of the caulk gun slightly away from the flange as you apply the silicone. This bead will act as both a sealant and an adhesive for the flange spacers.
Goal: Seal the existing flange
- For a thicker bead of caulk, pull the nozzle up and away from the surface as you apply it.

FAQs
Why do I need a toilet flange extender after tiling, and how do I know if I need one?
Tiling often raises the floor level, causing the existing toilet flange to sit too low. This prevents the wax ring from creating a proper, watertight seal, leading to potential leaks. You know you need an extender if the top of your existing flange is below the new finished floor level.
Is installing a toilet flange extender a difficult DIY project for a beginner, and how long does it typically take?
This project is rated as 'beginner' difficulty because it primarily involves careful measurement, cleaning, and sealing, not complex plumbing pipework. Most DIYers can complete it in approximately 3 hours, assuming all necessary tools and materials are readily available.
What are the most crucial tools and materials I'll need to ensure a successful, leak-free installation?
Beyond basic tools like a tape measure and caulk gun, a quality toilet flange extender kit and a reliable silicone sealant are critical. Don't skip on robust #10 3” wood screws for securely fastening the extender to the subfloor, as any movement can compromise the seal. Thorough cleaning materials are also essential.
What are the common mistakes to avoid when installing a toilet flange extender to prevent future leaks?
The most common mistakes include not thoroughly cleaning the old flange, failing to apply sufficient silicone sealant for a waterproof bond, and not securing the extender firmly to the subfloor. Always dry-fit the extender to ensure the correct height (flush or slightly above the finished floor) before applying sealant.
