Wondering how tall your shower curb should be? It’s not just about preference; it’s about meeting building code requirements too. Typically, if your shower drain is two feet away from the curb, you’ve already got a built-in clearance of about half an inch thanks to the slope of the shower pan.
For your shower curb to be effective and up to code, it should extend about 1.5 inches above the shower pan’s edge if your drain is four feet from the edge. This setup provides the necessary two inches of elevation change needed.
Curbless showers are an exception. They don’t require a curb if there’s no glass door, and the entire entryway remains open. This design seamlessly integrates into your bathroom floor, eliminating the need for any curb at all.
