What is the proper slope for a shower pan?
In a stall shower, the plumbing code requires the floor to be sloped one quarter (1/4) of an inch per foot in order to carry the water effectively to the drain. This slope, according to the TCNA Handbook is called “sloped fill” or commonly known as the pre-slope.

How do you find the slope on a walk in shower floor?
Measure from the drain opening to the furthest wall, then round up to the nearest foot. Calculate the slope by multiplying the measurement by 1/4 inch. For instance, if the drain opening measures 2-foot 8-inches from the furthest wall, then the shower floor should slope 3/4 inch from that wall to the drain.
