Why don't five-star hotels use trash cans in their bathrooms?

There is no trash can in the bathroom of a five-star hotel because sanitary ware can flush toilet paper. Because the bathroom space of five-star hotels is small, it is easy to breed bacteria and produce odor when it is wet all the year round. In order to ensure the health of passengers, sanitary ware is designed to flush toilet paper, so there is no trash can in the bathroom. Therefore, five-star hotels don't need trash cans in the bathroom, because sanitary ware can flush toilet paper.
