Question: When roughing in a standard residential bathtub, what is the typical minimum distance required from the finished wall to the centreline of the tub spout discharge for adequate clearance and functionality?
Answer options:
- 50 mm (2 in) ✅ 100 mm (4 in)
- 150 mm (6 in)
- 200 mm (8 in)
Correct answer: 100 mm (4 in)
Explanation: A typical minimum distance of 100 mm (4 inches) from the finished wall to the centreline of the tub spout discharge is generally required. This allows for adequate clearance for the spout itself and ensures water properly enters the tub without hitting the wall, as specified by manufacturer guidelines and good plumbing practice.
