Funchal Market has possibly the best public toilet facilities on the island. This delightful old building is crammed with vibrant colours of the flower, fruit and veg stalls is set on two floors. Visiting the surprisingly modern toilet facilities upstairs gives an opportunity to peer down at the fresh fish market below.

Avoid like the plague - unless you enjoy men looking lewdly at you as you go about your 'business'.
Carrer d'Alí Bei, 80
Not quite the reason to go to Chengdu, but should be useful. Nearly all toilets are 'squatties' so be prepared for some calf-stretching stability exercises. Slightly pricier restaurants have neat packets of tissue paper which you should nab whenever you eat there. Even cheaper restaurants have toilet paper available, so grab a bit if you are out. You never know when a touch of the Chengdu-doo-doo will hit you and you will be glad of your forethought.
For public loos (plenty of these on streets, by the river) you normally pay 2 jiao (0.2 rmb) to use them. Some are good, many are less than fragrant. Be prepared for them to be more public than you might be used to. Mens' and womens' are usually marked with picture symbols.
All over town - Chengdu is well endowed with toilets.
