What is the standard thickness of a brass toilet flange?

The standard thickness of a brass toilet flange is typically 1/8 inch. This thickness offers a balance between strength and ease of installation, allowing the flange to provide adequate support for the toilet while being thin enough to fit under the toilet’s mounting bolts without complication. A flange that is too thick could make it difficult to level the toilet properly, while a flange that is too thin may not provide the necessary durability or stability, leading to potential leaks or damage over time. This 1/8 inch thickness also aligns with common plumbing codes and standards, making it the preferred choice for most applications.
