Minimum Slope Shower Floor

We could find no reference to recommended slopes when trench drains are used in a floor.

Minimum slope shower floor.

So mark a line 1 1 2 from the floor all the way around the wall studs. It can be done but several steps must be taken to prevent water from going all the way to the sub flooring but to answer your question and i ve been doing it for 20 years the slope is a minimum of 1 4 per lineal foot i slope it a bit more depending on the shower size and how far it is to the drain. Remember that water will travel in the path of least resistance. I asked for the minimum slope and it looks like it is sloped 1 and 1 4 inch for 22 inches from left to right.

Thresholds should to be slanted inward at a 5 degree 1 4 pitch or slope so water flows toward the drain. Proper slope on shower threshold. Your finished floor after your liner and top mud bed are installed needs to be 1 to 1 1 4 thick at the drain. These stall should have no curb to allow the individual to roll into the.

So if we make the pre slope 3 4 thick at the drain it needs to be a total of 1 1 2 inch thick at all your walls. Land on the sloped curb and shed towards the drain and not onto your bathroom floor. This would be very much like a handicapped shower in its design a bit different but similar. Shower floor slope 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.

I am just trying to understand the code. My contractor has just ripped out my shower floor because it was very uneven.
