How to give a bath in a shower chair?

0 Hey guys, this is my first time posting anything to this site, hope to this works out.

I have just started my first clinical rotation and at this time we are focusing heavily on getting experience assisting with ADL's, but the clinical site I am assigned to has already provided a challenge that was not addressed in our training (only 2nd day). In lecture we were taught the method for giving a complete bed bath and checked off on that in skills lab. The facility I am assigned to, however, uses showers for anyone who can ambulate to an from a chair, even if they need fully dependent for hygiene care. So here is my problem: I can't quite figure out how I am supposed to preserve the patients modesty with a bath blanket, while cleaning rinsing them off with a detachable shower head. One other student and I were asked to assist with a shower and found it quite awkward and by the end the bath blanket was quite soaked. Also I am not sure how to clean the back side and perinial area if I cannot role the patient. Hopefully someone has experience with this technique or even better can direct me to tutorial of videa explaining the process. My clinical instructor was not entirely familiar with the process and the staff nurses don't want to be bothered as the facility is under staffed and the expect competence from the students working with them...
