Final answer:
Gutters in public shower rooms should be sloped at least 2% to ensure proper drainage and prevent safety and hygiene issues.
Step-by-step explanation:
Gutters in public shower rooms shall be sloped not less than 2%. This is to ensure proper drainage of water and prevent pooling and standing water, which can lead to slip hazards and bacteria growth. A slope of 2% means that for every 100 units in length, the gutter will have a vertical drop of 2 units.
