Is there really only one bucket in the VIP room where Japanese soup takes a bath?

No, VIP rooms with Japanese soup baths are usually equipped with a variety of facilities and bath options, not just a wooden bucket. The VIP room is usually equipped with a large bath or a plurality of small baths, and one or more wooden barrels or foot baths, so that guests can choose different bathing methods. In addition, VIP rooms usually provide more bath products and facilities, such as towels, shampoo, shower gel, sauna, etc., to provide a more comfortable bathing experience.
