You’ve probably noticed it a hundred times but never really thought about it– those two buttons on your toilet flush.

One small, one big. You press whichever feels right in the moment, without thinking twice. But have you ever paused to ask why there are two buttons in the first place?

No, it’s not some fancy bathroom design trend or an aesthetic choice to make your toilet look “modern.”

There’s actually a smart and super practical reason behind it– and it has a lot to do with how much water you’re flushing away every day.
