What is the iron bar under the hotel shower for?

The iron bar under the hotel shower you mentioned is actually a kind of handrail, that is to say, especially when some elderly people stay in the hotel, because the ground of the hotel is easy to slip. At this time, although there are many ways to carry out this mat, because there are no handrails, this safety hazard is reduced, so the hotel has strictly treated the sanitary facilities of this bath to prevent the elderly from falling and causing unnecessary trouble.
