Are there bags for shower stuff?

My university is in a different city than the city that I live in. I have one class this semester. Thus, I have to travel every week one day.

My problem is that every week I have to pack my shower stuff, such as shampoo, hair gel, body soap, deodorant etc.

I need to know if there is a specific bag for that. I am asking about a small (supposed) bag specially for these stuff.

I know that I can buy any small bag that suits me, but first I would like to know if there is a standard thing for this.
