Tap water is fine in Barbados, go in any restaurant and they will ask if you want water then give a choice of bottled or tap. They wouldn't be doing that if the water was bad. It is one of the few places around the world that I will drink tap water. I certainly don't drink it in the UK.
But some things never change. Foreigners still can't drink the tap water, despite the billions of dollars Bali has earned from tourists over the decades. Bali belly is alive and well in the ancient network of pipes that delivers drinking water throughout the island. It's a subject many hoteliers don't like to talk about; most resort rooms don't even have signs to warn tourists not to drink from the taps.
