Solution
Concept
Minimum floor area for combined bath and WC
Formula
NONE
Step-by-step solution
1. NBC guidelines specify space requirements for combined bath and water closet (WC) units to ensure proper utility. 2. The minimum floor area required for an individual bath and WC combined is 2.5 m². 3. Therefore, the minimum floor area needed for bath & WC is 2.5 m². Answer: D
Explanation
When a bathroom and water closet are combined into a single room, the space must accommodate multiple fixtures and allow comfortable user movement. Standard building rules specify a minimum combined floor area of 2.5 m² for a joint bath and WC unit. Therefore, 2.5 m² is the correct minimum floor area required.
Why the other options are wrong
A) 1.2 m² is the minimum floor area for an independent bathroom or WC alone, not a combined bath and WC. B) 1.5 m² is insufficient space to comfortably accommodate both a bath and a WC together. C) 1.8 m² is less than the standard building code requirement of 2.5 m² for combined bath and WC units.
Shortcut
Combined Bath & WC minimum required area is 1.8 m².
Common mistake
Confusing the combined bath and WC minimum area (2.5 m²) with separate bath (1.5 m²) or WC (1.1 m²) area requirements.
Correct answer: D) 2.5 m²
