We are 8 planning to take a private tour this Sept. Can we take bath every day in Tibet ?

Well, you are not advised to take bath every day. You are not advised to take a bath at first days when you arrived in Tibet. The reason way is not limited by the objective conditions, but because of the special geographical environment. For the first time visitors to Tibet, it takes time for the body to adapt to this environment. Even if there is no obvious symptoms of altitude sickness, it is equally inappropriate to take a bath too early.
