The rough in shower drain flange is installed in the master bathroom.
I had to use the power hammer to break up the concrete around the drain and eventually cut out a section of rebar to fit the drain below the floor. I trimmed about 2″ off the existing pipe and then filled in around the hole with expanding foam. The drain sits level with the concrete bottom of the shower.
The lineal pan drain I want to use will sit about 1″ above the rough in drain. The shower floor is recessed about 1 1/2″. I am hoping at 1/4″ per foot, I can slope the shower floor enough to have a curbless shower. In order to avoid two levels of shower pan, I plan to use a Schluter system which is described as a single layer system.
