The Philippines has a great name for toilets, they call the toilet the comfort room. Now unless you are rich there is no such thing as a comfort room, normally just a room with water all over the floor and water not running in the toilet itself. There will be no toilet paper available in the public toilets and if the toilets are blocked you still have to go- no choice.
If you are a guy, most public toilets are just going to the street and taking a leak. This leak will be in front of anybody walking past. There is no shame really. There may be a public toilet very near, but many will just pee outside. Some places you walk past just smell of urine all the time.
Many toilet seats are broken or just not there, and the toilet bowl if empty will have a few cracks in it for that perfect look. If you are Filipino and do use public toilets then you will need to take tissue paper with you into the booth, as there is very rarely nothing available in the room.
Many bathrooms still have no flusher which means that you must take a bucket of water and pour it at the correct angle and gravity will take care of the rest. I suck at this and usually end up with a toilet of diluted pee. Luckily this is becoming less common in malls but still very prevalent in private homes and small businesses.
Soap is really hard to find and often when you do find it, it is so diluted, it is mostly water. I guess a money saving measure. At a restaurant, you will often see the signs for the employees outlining hand washing. Better not to think too much about how the chef is washing his hands without soap.
Most bathrooms will have signs stating please throw tissues in the trash. Tissue is usually not supposed to be flushed. Most of the tissue paper stays in the bowel as water pressure can be very low and the throwing of water down the bowl does not really move tissue paper.
So, as a visitor it is just best to bring toilet paper with you and just learn to cross your legs and wait. If urgent for a guy do not PEE on the street as that’s disgusting for a foreigner to do that and you can be fined, and that will never really happen to a Filipino where it is just accepted.
