If coming into a physical space, new employees should come in on their first day to a clean workspace and basic work necessities. If your new hire is a remote employee, all basic necessities should be sent to them well in advance of their start date.

You can also contact your new hire directly and ask them what items they will need to feel comfortable in their working environment.
