In all honesty - don't. If you try to make her do it before she's ready, you're both in for a long miserable road.
Just buy her a potty & let her do with it what she wants. If she wants it in her room, fine. Living room, fine. Bathroom, fine. Drag it around the house with her.... that works, too. Let her take the lead.
