Gabon
It's bins I'm afraid. Put the paper in either the bin provided, or put it in a plastic bag and take it with you to dispose of properly.
Gambia
The locals prefer holes in the ground-style toilets and washing rather than paper. In these toilets you'll be using a bucket of water to flush, so take paper with you or put it in a bin if provided. Some more basic pits are just covered when full and a new hole dug in place, again it's best to take the paper with you as it doesn't break down properly. There are flush lavatories with septic tanks that are periodically emptied, but it's best to check whether these systems will take paper.
Georgia
It's mostly squat toilets in Georgia; however, European-style toilets are on the increase in more upmarket establishments. You'll probably need to put the paper in the bin or take it with you.
Germany
There dashed clever these Germans. In all but the very oddest of cases you can flush the paper down the toilet. Germans are poo-obsessed, so bear in mind that their toilets have little shelves or slopes at the back so, before you flush (presumably several times to shift everything in some cases) you can have a good old look at your producings. Lovely.
Ghana
Bins are the norm in Ghana, although you'll be lucky to be supplied with any paper.
Greece
In Greece, it's paper in the bin time again I'm afraid. The Greek plumbing system can't take paper and it'll be bunged up and flooding if you try to flush the paper. Newer, up-market hotels should be able to accept the papery deposit, but in most cases it's best not to risk it.
Grenada
Did you know it's illegal to swear in public in Grenada? It is, so be careful how you phrase the "where do I put the paper?" question; in answer, bin it.
Guatemala
In common with a lot of Central and South America, the bin by the side of the toilet is for putting paper in and the sewage system and toilet pipery can't cope with paper.
Guinea
In common with much of west Africa you'll be cleaning up with your hand (make sure it's your left hand) and water from a colourful teapot provided if you're living like the locals. If you're using paper, use a bin of provided, if not, dispose of it sensibly. You can't flush the paper.
Guinea-Bissau
Carry your own paper and take a rubbish bag to take the used paper away with you.
Guyana
It's fair to say that if you've done any travelling in South America you quickly learn that you'd better have a roll of toilet paper with you, and you'd better not try and flush it if you don't want the loo to block and flood the floor. Throw paper in the bin, or take it with you and dispose of it properly.
Haiti
There's no such thing as a public toilet in Haiti and anywhere you do go the sewage system will be basic and overstretched at best, so don't try and flush anything; throw your paper in the bin provided or take it with you. The locals are more than happy to relieve themselves behind bushes or just at the side of the road, so don't worry if you get horribly caught short.
Honduras
Western-style toilets are pretty common, but you really don't want to try and flush anything; put your paper in the bin provided.
Hungary
You should be alright to flush the paper in most places in Hungary. Water pressure may be an issue in older buildings, but in the most part the sewage system can take anything you can throw at (in?) it.
Iceland
You will be excellently serviced for public toilets in Iceland and, like the rest of the Scandinavian countries, flushing the paper is no problem.
India
Indian toilets employ a 'wash and go' cleaning facility in the vast majority of cases. If you are going to use paper, put it in the bin provided. Oddly, the internet tells me that there are more mobile phones in india than toilets; I wonder what the ratio is in the UK.
Indonesia
Wash where possible, don't flush. There is an excellent How To... guide on using traditional Indonesian toilets here and presumably this translates nicely for other squatting toilets worldwide.
Iran
The internet suggests that if you can get hold of local paper, it will be huge; twice the size of Western-style paper. Whatever you do though, don't try and flush it, the water pressure is too low and the pipes are too thin to take anything but poo. Iran is another country where the wash-and-go option is preferred by the locals.
Iraq
Yep, you guess it, Iraqis are the fans of the old 'squat and wash' method of using the toilet. If you do have paper, put it in the bin, the holes in the ground and pipes really can't take anything else.
Ireland (Republic)
They might not have any money, but the Irish are more than capable of flushing the paper. Just as well really, all the Guiness and you'll be needing a proper facility.
Israel
Apparently the biggest problem you're going to face with Israeli toilets is the over-exuberant water pressure and flushing action: stand well back. You may well be startled (and presumably unexpectedly washed) by automatic flushers in some public toilets.
Italy
Usually Italian toilets are very powerful and can shift a lot. Feel free to flush unless specifically told not to. Having said that, public toilets are few and far between in most major cities and tend to be pretty unpleasant. Supposely you can use restaurant and cafe facilities for free, but you might be wise to buy something cheap if you're likely to be going back.
Ivory Coast
There is a severe lack of sanitary toilet facilities of any type in Ivory Coast and public health is a major problem. Composting toilets are slowly being introduced wherever possible, but it's holes in the ground that leak straight into the water table in a lot of places. Take your paper with you and dispose of it somewhere safe or burn it.
Jamaica
Public toilets are few and far between and often unpleasant. Waterless composting toilets are being introduced slowly to help with environmental problems. Wherever you happen to go, you'll be throwing the paper in the bin, don't flush it.
Japan
Japanese toilets are incredible space-aged and, if television has taught us anything, are practically intelligent, so you can flush the paper and you'll probably have your weight measured before and after and a pleasant chat or piece of music as you're using the facilities.
Jordan
The Lonely Planet seems to suggest that public toilets should be avoided at all costs, but provides no extra detail. Maybe they're infested with scorpions? You'll find both squat and Western-style toilets, but neither can take flushing your paper, so always use the bin provided.
Kazakhstan
Both the flush systems and holes in the ground usually seen in Kazakhstan are unable to deal with toilet paper, so throw it in the bin. It's also worth bearing in mind that ex-Soviet countries favour large-grain sandpaper style paper, so make sure you've got some lovely soft three-ply with you. Oh, and public toilets are often dark, so a torch will come in handy.
Kenya
Sanitiation in Kenya is a massive problem, and out of the cities you'll be lucky to find anything better than a public pit latrine. Eco-friendly composting toilets are being introduced, but wherever you go, take your paper with you and bin or burn it.
Kiribati
Until fairly recently, just going where you could seems to have been the norm on Kiribati; fortunately this is changing and sanitary systems are being introduced. Bin or burn your paper.
Korea (North)
If you happen to find yourself in North Korea and can find a toilet that doesn't have a microphone listening in to your every word (imagine having the job of listening in to that), you'll probably be throwing the paper down the hole you use, but you can flush it in most decadent Western-style toilets. Who says Communism is a bad thing?
Korea (South)
In general, South Koreans don't flush their paper, they put it in the bin that is provided by the toilet.
Kosovo
Toilet facilities are very limited in Kosovo; carry a good supply of toilet paper and bin or burn it when you're done.
Kuwait
If you can find a public toilet in Kuwait, well done. Kuwaitis are mostly washers not wipers so the sewage system can't deal with paper. Put it in the bin.
Kyrgyzstan
It's ex-Soviet sandpaper again in Kyrgyzstan; in towns, holes in the ground and the incredibly rare Western-style toilets can't deal with the paper so bin it. If you're caught short in the countryside, dig a hole and burn the paper.
Laos
Public toilets are horrific and mostly squatters. Take your own paper with you and throw it in the bin provided afterwards.
Latvia
The bathrooms of the Baltic states have been transformed since the fall of the Soviet Union. None of your crap-in-a-hole problems here and, joy of joys, in the vast majority of places you can flush to your heart's content. That said, outside of the main cities and in the older parts of Riga, you may be binning but it should be fairly obvious.
Lebanon
In many toilets the sewage and flush system is too old to take paper, so don't flush, bin it.
Lesotho
According to the United Nations, the majority of people in Lesotho have no access to proper toilet facilities and sanitary conditions are terrible. You won't be flushing your paper even if you find something that could pass as a "normal" toilet (squat or otherwise). Bin your paper as long drop holes in the ground are the norm.
Liberia
Sanitation in Liberia is horrific and disease is rife. Open sewers are the norm, so paper put into the system will quickly lead to health and vermin problems. Bin it as cleanly as possible, or burn it if you have to use paper.
Libya
Public toilets don't exist, try and use a hotel if you're caught short. You'll be binning the paper, and you'd better be carrying some about because it's not in massive abundance wherever you are.
Liechtenstein
Ruthlessly efficiant these Liechtenstineans (?); flush the paper with alacrity. By many standards, Liechtenstein is considered to have the best public toilets in Europe, I bet that's a hotly contested award every year.
Lithuania
Same as Latvia really; clean, decent toilets that can take flushing the paper. Enjoy!
Luxembourg
Public toilets are rare and you'll be expected to leave a small tip (a few cents), but are generally clean and well maintained. Flush the paper.
Macedonia
Not the greatest of facilities, but in upmarket and European-style hotels you'll be able to flush the paper. In other places, there'll be a bin by the side of the toilet so throw the paper in there.
Madagascar
A lot of Madagascans don't have access to suitable, sanitary toilets, so you'll be lucky to find anything remotely Western-style. Bin your paper.
Malawi
Sanitation is a big problem in Malawi, with clean water and sewage systems that aren't riddled with cholera being very rare; unprotected pit latrines are very common and very unpleasant. Don't try and flush paper, bin it.
Malaysia
Public toilets are so bad they'll test the stamina of even the most rugged traveller. If paper is provided, don't flush it as the system just can't cope. In upmarket hotels you'll probably be ok to flush, but as the locals tend to wash not wipe, you'll be better of binning the paper if a basket is provided, just in case.
Maldives
Most villages now have composting toilets and Western-style toilets are available in the most tourist-minded locations, although a lot of them will be outside and unroofed. Wherever you go you'll probably be washing if you want to blend in; however you chose to go don't flush toilet paper.
Mali
Pollution – water and crap (literal and metaphorical) just lying about everywhere – is a big problem in Mali. All toilet paper should be burned or buried.
Malta
Generally good and clean, plenty if public facilities, but be prepared to pay/tip. Flush the paper.
Marshall Islands
You're not going to find anything approaching a posh toilet here, mostly they'll be very simple systems where your flushing with a bucket of water. Burn or bin the paper, don't flush.
Mauritania
Chances are you'll be crapping in a hole in the ground and burning or burying the paper.
Mauritius
You'll be binning I'm afraid.
Mexico
A lot of the time you're going to be throwing the paper in bins, so keep an eye out for them. Some higher class hotels have European-style flush toilets, but it should be fairly obvious which are which.
Micronesia
You're unlikely to come across a flush toilet. Bin the paper.
Moldova
Many toilets will have a bin by the side for the paper so use that, generally speaking you can't flush the paper or other products.
Monaco
One of the richest countries in the world. Crap away in luxury and flush happily!
Mongolia
Again, the local plumbing is falling apart and can't take anything in the way of paper or other products. use the bins provided.
Montenegro
Montenegro is a lovely place. You'll still be crapping in a hole and using the bins for toilet paper though, sorry.
Morocco
In Morocco there should be a little bin by the side, use that. Or use the local method if there's a bottle or jug of water. This is largely dependent on whether the hotel/restaurant etc has enough water pressure and/or a decent septic tank.
Mozambique
Most areas of Mozambique would consider running water an unaffordable luxury. Those that don't, don't waste much using it to flush toilets so be careful and, if possible, use a squat toilet with a flushing bucket. Throw your paper in the bin, the systems can't cope with it.
Myanmar (Burma)
Why are you in Myanmar/Burma? Good grief, come home now. If you happen to find a toilet (and these days they tend to be Western-style sitters rather than squatting over hole sorts), put the paper in the basket or bin provided. It's worth noting here, that if you're caught short on the road, it's best not to go too far off track to find a bush as there are an awful lot of landmines littered about.
As far as possible this stuff is correct, but it's always best to check with a friend before lobbing dirty loo paper in a bin. If it's obviously wrong, you can email me here. ©2010-2011 for all the good that'll do. Made by @mattkitson; In real life I am a freelance medical writer.
