Making ghusal in a shower

Q:

1. As most houses have showers in the bathrooms for taking baths. Please advice what will be the way for taking ghusl-e-janaabat with shower.

2. I have hip dislocation from birth due to which I am not able to lift my legs after a certain height. As in most of the offices there isn't a proper place for wuzoo and people doing wozoo in the wash basin also wash their feet in the wash basin. My problem is that I can't lift my legs till the height of the wash basim. What should I do in that case?
