Step 1: Cut Subfloor and Set Drain
NOTE: This drain can be installed with or without a shower curb. If the curb is used, then the subfloor does not need to be cut out.
Step 2: Blocking to Support the Subfloor
Step 3: Create Slope to Drain
When the proper height is calculated, draw a line to use as a guide when creating the mortar bed slope. If the shower is larger, it will be necessary to add blocking between the wall studs to accommodate the height of the mortar.
The mortar sits right on the subfloor. All waterproofing will be done after the drain body and mortar bed are installed.
