Short answer: No, it’s very likely not misrepresentation.
There are a few reasons the published area and your simple length × width calculation don’t match exactly.
⸻
1) Published area usually includes usable floor area
When developers list a room or bathroom size like “9 sqm,” they generally refer to the usable floor area — which may include:
• Curved or irregular corners
• Areas behind door swing clearance
• Slight wall recesses
• Minor built‑in cabinetry recess
Your straight 2.5 × 3.2 assumes a perfect rectangle, but real floor shapes rarely are.
So even though 2.5 × 3.2 = 8.0 sqm (gross math), the actual measured usable area can be slightly larger once you include the full usable footprint.
⸻
2) Measurement rounding and engineering practice
Developers and surveyors often:
• Round figures to the nearest full number
• Use industry‑accepted tolerances
• Include small pockets of space that a simple length × width doesn’t count
A difference of 1 sqm (about 12–14 sq ft) is very common in property listings.
⸻
3) Where the “9 sqm” likely comes from
• Architectural plan measurements
• Floor plan area from the Singapore Institute of Surveyors and Valuers (SISV)
• Approved plan dimensions excluding structural walls
These tend to be slightly more generous than on‑paper rectangles.
⸻
4) What would be misrepresentation
If the developer claimed:
• 9 sqm usable bathroom PLUS extra space that doesn’t exist
• Gross usable area much less than published
Then it might be questionable — but a 1 sqm difference is generally within normal measurement tolerances.
⸻
5) What you can do if concerned
✔ Ask the developer / sales team for floor plan sheet with area breakdown
✔ Request architect measurement notes
✔ Compare with similar units to see if consistent
If the published size was significantly smaller or misleading, then you could raise it — but in everyday practice, this level of variation isn’t treated as misrepresentation by authorities.

Quick summary
???? 2.5 × 3.2 = 8.0 sqm is a rough rectangle area
???? Developer’s 9 sqm likely includes usable area pockets and measurement tolerances
???? Not usually considered misrepresentation for a 1‑sqm difference

If you want, send me the exact floor plan and the published spec — I can double‑check where the extra area comes from and whether it makes sense.
