No head no tail.
New HDB or 40 years left?

Neighbour upstairs overweight?

Looking at the tap and pipes, it should be a very vintage HDB flat. Maybe built in the 1970s or 1980s.

lemme guess... HDB flat built between 2000 and 2010.

substandard cement? some sand. not enough gravel and aggregate.

I have noticed that the cement on newer pavements and walkpaths are not very good... it becomes 'brittle' and 'powdery' after a while. The older pavements never experienced such a problem, and they only break if a tree root underneath grew too big.

I think it started around the time when Malaysia stopped exporting sand to Sinkieland for making cement. Sinkieland got the sand from elsewhere and/or started making its own cement.

the art and science of making concrete (that can last for at least 69 years) is lost on sinkie, taiwanese and tiong contractors. never trust concrete mixed and cured among these 3some of cuntries where local contractors bid low to win construction projects with low budgets, unreasonable timelines, and dubious structural and architectural designs.

How come never take picture of the hole in the ceiling?

Wonder what is up there.

Shouldn't it be another toilet?

the rebar lines indicate half of the ceiling slab came down while other half is still intact as the "floor" of flat upstairs. so may be no lobang to sexplore and see? this may indicate poor concrete adhesion and or bonding among its composite materials: fine aggregate (usually sand), coarse aggregate (usually gravel), and cement. this concrete failure below has a lack of sand or fine aggregate, as fine aggregate helps to fill up crevices, holes, and spaces between gravel or coarse aggregate and bonds with the cement to make the concrete denser. without fine aggregate, the cement will crack and break away from usually where the rebars and coarse aggregate are as bonding weakens over time. ask any fly by night contractor in sg and jiuhu (don't need to mention prc and tw), and they have no clue what makes good reliable concrete. all they know is anyhow humtum mix this mix that shit. i grew up in my childhood years watching fly by night contractors, foreign workers with hardly any sexperience, and samsui women mixing concrete at construction sites during the early years of hdb construction. amount of materials anyhow humtum. plus they used wooden poles and planks to construct scaffolding and tied them up with wet bamboo strips. no wonder the vertical and horizontal lines were crooked. you can still see crooked lines on hdb blocks that were built in the 60s thru' the 80s.
