Recommended sand baths (container and sand) for dwarves?

Hi all!

I'm bringing home a girl dwarf hamster on Thursday, and have been a bit puzzled as to how big of a sand bath container to get her, and what material (glass, plastic, etc). She's very small, even for a dwarf hamster (vet visit imminent to ensure this is just... her, and not some pervasive health issue). I've really only had Syrians in the past so my sense of scale is a bit off. I was going to facilitate it with reptile sand, but I was equally wondering if anyone has any preferred brands or any types/sub varieties I should look for.

tl;dr: what it says on the tin: what size bath container, what material bath container, what preferred types of sand?

Thanks in advance!
