Identify and Assess Wall Imperfection

What happens here

The video begins with a demonstration of a common issue in construction: a shower wall stud that is either not perfectly plumb (vertically aligned) or is bowed along its length. The presenter uses a long orange level to illustrate this. When the level is held against the stud, the bubble in the vial is observed to be significantly off-center, indicating that the stud is leaning inward or outward, or is curved, rather than being perfectly straight and vertical. The presenter points out the gap behind the level, further confirming the imperfection.

Goal: Confirm that the shower wall stud is not plumb or is bowed
