How to Install Tile Shower Pan

Step-by-step guide to installing a leak-proof shower pan

Difficulty: Moderate

Instructions

Things You'll Need:

• Cement
• Sand
• Level
• Hammer
• Roofing nails
• Silicone sealant
• Chalk Line
• Trowel
• Utility knife
• Drain assembly(bottom already installed)

1. The first step is to 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. TIP: Try not to stretch the membrane when nailing to the studs. It should be tight but not stretched.

2. Now it is time to 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, press, apply sealant to the bottom side of the upper piece, then install bolts tightening equally around.

3. 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 4:1 (sand: cement) mix. Mix should ball easily in 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" to 4" depending on preference.
• This is the foundation of your new shower floor. Take the time necessary to do the job right the first time.
• Read warnings on any products used before using them.
• Always wear safety glasses when working with tools!
