Shower Pan and Tub Combo
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 is required to have a damn, which is at a very minimum 3 inches high. the shower damn is normally constructed of 2 or 3 (2 x 4’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. Applies 3a. and 3b.
4. A platform has to be built where the tub will sit. This platform can be as low as 2 3/4 inches high from the subfloor. It should also have a hot mop drain or proper tub free standing tub drain.
5. In this shower there are two drains on the shower side of the combo, placing a flat 2x4 in the center of hte shower helps to properly slope the drains on each end.
