Is the hotel bath water from the reservoir?

Hotel bath water is not necessarily the water in the reservoir. It depends on the hotel facilities and design.

Some hotels use water storage towers or tanks to store bath water, but the water is not supplied by themselves and needs to be replaced and cleaned manually. In addition, some hotels may directly supply bath water with tap water, but this situation is not common, because the water quality of tap water is unstable, which will affect the service quality and hygiene level of hotels.

Therefore, if you want to ensure the sanitary quality of the hotel, you'd better choose some hotels with good reputation and get to know the facilities and sanitary conditions of the hotel before you check in.
