What is the minimum pitch for a shower drain?
about 4 percent
To efficiently drain, the recommended minimum slope for a shower floor is about 4 percent, or a 1/2 inch drop per every 12 inches from the shower walls to the drain. In traditional tile shower construction, this slope is established in the mortar pre-pan.
Does a shower drain need to be sloped?
Step 1: Floor Tile Must Slope to the Drain 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 thick should my shower pan be?

Pipes Must Slope Plumbing AND vent lines are all supposed to be installed with pitch or fall. The generally accepted minimum pitch is 1/8 inch per foot of run. You can also install pipes with 1/4 inch of fall per foot of run, but I’d be careful about exceeding that slope.
What should the slope of a shower drain be?
Lining up the P-trap so that it is directly under the drain hole will make the installation much easier. A shower drain pipe should have a pitch, or slope, of 1/4 inch per foot. Mark and drill holes in the floor joists according to this slope.
What’s the best way to install a shower drain?
