Minimum width of WC in residential buildings
Formula
NONE
Step-by-step solution
1. Building bylaws specify dimensional standards for water closets (WC) in residential buildings to ensure usability. 2. The minimum width recommended for a WC enclosure is 0.9 m. 3. This width allows comfortable access and proper fixture installation within the space. Answer: A
Explanation
In residential building planning, a water closet room requires a minimum width of 0.9 m to provide adequate ergonomic space for proper usage. This width allows comfortable seating and movement within the space without feeling restricted. Therefore, 0.9 m is the prescribed minimum width requirement.
Why the other options are wrong
B) 1.0 m exceeds the absolute minimum required width for an individual w.c. C) 1.2 m is typically the minimum width required for a combined bath and w.c. space. D) 1.5 m is much larger than the minimum functional width needed for a residential w.c.
Shortcut
Minimum width for a residential W.C. is 0.9 m.
