Seems you have one of em stubborn ones. Will take lots of patience but if you keep at it and are consistent with your commands, you will get through in time.
Main tip I will throw in is to teach her her name. Using a clicker and rewards, start in the bathroom with closed door and a handfull of high value treats ( VIP Chicken Chunkers/steak/pork sausage/cheese) and call her name. If she moves an eyelid in your direction, click and reward. 5 minutes and let her go. Rinse and repeat but as you get more and more reaction to her name, hold back on the click and reward. When you get a fast head turn or she is moving towards you, move to a larger room with distractions but go back to step one as far as the click is concerned. Rinse and repeat and move outside where you start again with the click if she so much as looks at you.
Whole idea here is to show that if you call her name a reward will follow but take small steps and ensure you have a strong connection before you move on. You could then try using a long line to reinforce coming when you call her name.
