What is the required waste outlet opening size for individual shower compartments?

A. 1 inch
B. 1.5 inches
C. 2 inches
D. 3 inches

The correct answer is: C. 2 inches

The required waste outlet opening size for individual shower compartments is typically set at a minimum of 2 inches. This size is established to ensure adequate drainage and to prevent clogging, as showers can generate a significant volume of water discharge. A 2-inch opening allows for effective removal of water and accommodates various plumbing systems while complying with standard plumbing code requirements. This feature is particularly essential in preventing backups and ensuring the longevity of drainage systems.
