Are Toilet Seats Universal?

Let’s be honest—shopping for a toilet seat shouldn’t be complicated. But when it comes to compatibility, most toilet seats fall short. From mounting issues to shape mismatches, the truth is: toilet seats traditionally aren’t universal.

However, we’re rewriting that narrative. With its growing lineup of universal-fit toilet seat solutions, including the revolutionary Universal Fit™ series, we make it easy to find a seat that fits your needs—and your toilet—perfectly.

Why Most Toilet Seats Still Aren’t Universal

Despite being called “standard,” toilets can differ in small yet important ways:

• Shape Matters: Round vs. elongated bowls demand differently contoured seats.
• Bolt Spacing Varies: Some seats won’t match your toilet’s mounting hole distance.
• Installation Hardware: Many traditional hinges loosen or misalign over time.

These minor differences often lead to major frustration. That’s exactly what Bemis set out to fix.
