Oatey Toilet Flange Extender Kit, Set-Rite, 1/4 to 1-5/8 in

Overview

Renovating a bathroom can reveal an imperfect toilet flange height, which may lead to misalignment and imperfect sealing around the base. The Oatey Set-Rite Toilet Flange Extender Kit is designed as a watertight solution that lets you raise the flange surface above the finished floor. With a properly positioned flange, a standard wax ring can seat more evenly, helping you achieve a cleaner, steadier base for your toilet.

Why choose Set-Rite for your remodel

This kit focuses on fit, durability, and ease of use, so you can adapt to existing plumbing without major changes. The design supports a confident retrofit, delivering a solid foundation that can contribute to a steadier toilet posture and a neater bathroom floor line.

What’s included

• Four spacers in varying sizes to reach the target height
• Six self-tapping screws for quick, secure mounting
• Complete hardware for typical flange extensions, compatible with common pipe work
• Construction designed to endure typical bathroom use and reconfigurations

Compatibility and use

• Works with PVC, ABS, cast iron, or stainless steel ringed flanges
• Extends flange height from 1/4 inch to 1-5/8 inches above the finished floor
• Designed to create an optimal seal with a standard wax ring

How it helps in real life

During remodels, flooring changes or flange misalignment—common bathroom refresh scenarios—the Set-Rite kit provides a practical path to restore proper flange height. The result can be a more stable toilet base, a consistent base line around the toilet, and a cleaner transition where the floor meets the fixture.

Installation notes and tips

• Shut off water, drain the line, and remove the existing hardware as needed
• Plan the desired height using spacers before tightening screws
• Securely fasten the kit to the flange, then set the wax ring per standard practice
• Inspect the area for a clean seal and run a test flush to verify alignment

Oatey has earned the trust of plumbing professionals for over a century, and Set-Rite continues that legacy by offering a practical, adaptable solution for flange height challenges.
