Step 1: Cut Subfloor and Set Drain

Use the drain body as a template to mark the subfloor.  Cut out the subfloor so that the flange rests on the floor.  You will notice that the flange is the thickness of typical floor backerboard.  The backer board will butt up against the drain body on the bath floor outside the shower.

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

2x6" blocking is added to support the floor, outlining the area where the subfloor is cut away for the drain.

Step 3: Create Slope to Drain

Create the slope by finding the place on the studs that is level with the drain body.  Add 1/4" of height for every foot of width.  I had 2 1/2' of shower pan to cover, so that adds up to 5/8" extra height was needed.  The skills needed to create the mortar bed are very similar to those needed when creating a mud pan.

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.
That looks like a really nice neat job, thanks for sharing your advice and experience.

Really beautiful! Never seen this before, why continuing to install 'hole drains' once you saw this?!
Very interesting. Thanks
