What is the minimum slope of a finished shower floor according to the California Plumbing Code?

1/4 inch per foot
1/8 inch per foot
1/2 inch per foot
3/8 inch per foot

The correct answer is: 1/8 inch per foot

The minimum slope of a finished shower floor according to the California Plumbing Code is indeed 1/4 inch per foot. This requirement is crucial because it ensures proper drainage of water toward the designated drain, helping to prevent water pooling and potential slips or falls in the shower area. A slope of 1/4 inch per foot strikes a balance between effective drainage and user comfort, allowing for a safe, functional shower space. If the slope were less than this, such as 1/8 inch per foot, it might not facilitate adequate water runoff, leading to standing water and increased risk of mold or bacteria growth. On the other hand, a slope that exceeds this minimum (like 1/2 inch per foot or 3/8 inch per foot) could be uncomfortable to stand on and may not be necessary for effective drainage. Therefore, adhering to the 1/4 inch per foot guideline helps ensure both safety and comfort for users of the shower.
