Slope Of A Shower Floor Lip

This post describes the top or overlay of the curb for your traditionally waterproofed shower floor with a liner.

Slope of a shower floor lip.

It will take some time and patience the first time you do it but the reward is that you ll have a perfectly sloped shower pan. To determine the proper slope measure from the drain to each wall and figure a quarter inch of slope per foot of length. It assumes my posts often assume quite a bit they are condescending little bastards that you already have the curb substrate built your preslope in and the liner installed. Continue this process around the entire shower pan.

This will literally lay the groundwork for a beautiful new shower tile floor. If the wall is 3 feet from the drain the cement should rise by 3 4 inches as it goes from the drain to the wall starting at the half inch depth around the drain for a total height of 1 1 4 inches at the wall. 3 16 to 1 4 pitch or slope so water flows in toward the drain. 36 should be considered the minimum depth for any curbless shower.

Using thinset to create a 2nd pre slope on the shower pan in order to give it enough pitch so the water will flow. The curb or lip around the bottom of the shower should to be slanted inward at a 5 degree approx. The larger the shower the easier it is to gradually slope the shower floor to the drain and contain water. A level curb would cause the water to stand while a curb angled away from the drain would cause water to leak onto the bathroom floor.

Overall shower unit size length and depth are critical for water control. Once you ve screeded the slope use a wood float to pack the mud down.
