1. Ensure that your subfloor is flat and level. If not, use leveling compound before beginning installation. Locate drain

position and arrange pan pieces to center over drain area. If the area is smaller than the pan or pan plus extension(s),

trim foam with a fine-toothed hand, power saw, or utility knife and straight edge - preferably equally from each side

until the pan pieces fit the custom space properly with the hole centered on the desired drain location. If the overall

pan size is smaller than the desired floor plan by more than 1/2”, dry-pack mortar mix may be used to extend the size of

the shower pan where needed. When using dry-pack mortar (the mix ratio is usually not critical for small “patch” areas

- 3:1 to 5:1 sand to portland cement should be fine), be sure to protect a wood subfloor with tar paper. For gaps of 1/2”

or less, you may use modified thin-set mortar which can be directly applied to wood surfaces.
