How to Install Tile Shower Pan
A leak-proof shower pan is essential when putting in a new shower. Water that leaks from the shower around the drain area will cause substantial problems over the years. A shower pan will keep all the water contained so that it goes properly down the drain. This task must be done before the flooring for the shower has been laid. Does this Spark an idea?

Center the new membrane on the floor of the shower. Once it is centered and fairly flat, fold the corners (do not cut to fit always fold) and nail into place. Also, nail at each stud to secure the edge of the membrane. Try not to stretch the membrane when nailing to the studs. It should be tight but not stretched.

Put in the drain. Begin by laying out with a marker where the drain assembly bolts will come through the membrane. Carefully cut a circle using the bolt hole marks as a guide. Be sure the bottom of the drain assembly is clean. Apply a sealant between the lower assembly and the membrane and press it down. Apply sealant to the bottom side of the upper piece, then install the bolts tightening them equally around.

Before applying the cement, trim the membrane at the doorway, fold over and secure with roofing nails. Mix the cement as directed, then add sand to make a 4 to 1
sand/cement mix. The mix should ball easily in your hands. Snap a level line around the outside walls to reference when leveling and pitching cement. Be sure to check pitch and other specs of shower being installed. Use the level and trowel to achieve a nice evenly pitched shower base. After this the tile can be installed.

Tips & Warnings
Read and understand all directions before beginning project.
Be as precise as possible when leveling and pitching the mud.
Check for low spots in mud so water does not have a place to collect after floor installation.
You can also use a wood "float" to pack the mud, but the trowel will work.
The mud layer can be anywhere from 2 inches to 4 inches depending on preference.
Always wear safety glasses when working with tools!
