The issue of toilets and what to do with used toilet paper can cause confusion. In general, if there’s a wastepaper basket next to the toilet, that is where the toilet paper goes (many sewage systems cannot handle toilet paper). If there’s no basket, flush paper down the toilet.
Toilet paper is usually provided though it’s wise to keep a stash of your own while on the move.
There are still some squat toilets in public places and out in the countryside.
The scarcity of public toilets is more of a problem for women than for men. Vietnamese men often urinate in public. Women might find roadside toilet stops easier if wearing a sarong. You usually have to pay a few dong to an attendant to access a public toilet.
