The water

Tap water is drinkable. Moreover, Sweden has one of the best water in the world, one of the purest, because most of the water comes from snowmelt, and basically there is a lot of water.

The hot water comes out very fast and very hot, and there is a myth (I do not know if it's true) that they hot it by chemical products. That means that it is not harmful to drinking it, but better if you do not do it. It is better to heat the cold water, but takes longer, or heating in water-heating equipment (for tea).

Of the bathrooms you can also drink, and the cold water comes out very cold. If you buy water in supermarkets, or in a restaurant, be careful, because most of the water is sparkling!
