Is the water in the hotel bathroom the water in the tank?

At present, the water in the hotel bathroom is a set of tap water pipes, and the hot water is supplied by the water tank, which comes from the same place as the water in the kitchen. Water sources vary from place to place, some are surface water and some are groundwater.

Hotel bathrooms generally do not need to consider water heaters, because hot water in hotels is usually supplied by hot water tanks, and only some small and not very good hotels will use water heaters.
