I would say that no Mamotte bathroom is complete without towels . . . but these are the only bathroom-related items. XD
I've never seen these in person but it looks like the larger Shao towel is a body towel. The small Rishu towel is probably a face cloth. The illustrations on these are really cute. I love Rishu (of course) because of her adorable outfit and despite her comically oversized feet!
