Need Advice/thoughts on when to clean Poop up in shower

I have a questions for all my cna's. Ive just started working at this Rehab / LTC facility. Ive went above and beyond my duties as a CNA.I love my patients and love working with them. I clean my patients and they are never left smelling. I guess to say im not a lzy CNA. Not to be graphic but here it is....

My concern is today I took my patient into the shower and he pooped a big pile of poop.I dont think towels would cleaned it up.( it was watery).Besides I couldn't sweep it away with the shower like I would normally do because the shower head couldnt reach where it was. You needed the right tools( a mop to clean it up). So i called housekeeping and they told me they would clean it up, so I went about my day . After im done with my shift. The HR person comes to me and asked why I didnt clean it up. i told them i called housekeeping earlier. She said that they didnt do that, only if it is a small job. I informed her that they said they would clean it up.

Hello... if its a small job I can do it. After the conclusion when I found out I had to do it. I just picked up the towels I put over it and left.

Im wondering if Im wrong in any way. is it our jobs to pick up a big pile of watery poopor? isnt that where housekeeping comes in when we can't clean it up properly. Any thoughts or concerns
