Prep Guide
Standard Shower Pan
1. All showers need blocking between each stud, which should be 12 inches high from the floor up. Same applies to (1a.) & (1b.).
2. Every shower needs a damn, which is at very minimum 3 inches high. The shower damn is normally constructed of 2 or 3 (2x4’s) stacked flat on top of each other at the entrance of the shower.
3. An installed shower drain always needs to be flush with the floor. The correct shower drain will have a top and bottom flange held together by 3 or 4 removable bolts.
