In some premium hotels (not IHG) & eco resorts I have already seen shampoo & shower gel in small ceramic / stone like dispensers . It felt more premium then small plastic bottles. I can’t imagine that an IC just puts the same system as a HIX, hence it is a nice move if we see those small premium dispensers.
in the following photo for instance it is a stone like product in Alila Jabal Akhdar
