Pengilih Point / Toilet blocks / #15 on the layout map

Single toilet cubical, possibly for officer use only?  

Functional local squat style toilets for both enlisted men and officers. These squats are easily constructed on site, bypassing the need to bring in physical toilet bowls from Singapore.

Latrine block beside the mess and cookhouse. The opening is where the removable latrine bucket was placed inside. 3 toilet cublical block probably for enlisted men?
