As in, actually getting my 14 month old clean in a standup shower.

My ambitious husband tried to fix something in the shower/tub, and now can't get it back together again. While he waits for a part (or divine intervention) we are bathing in the stand up shower in the guest bath, which is fine for us but challenging with a one year old. I put her tiny blow up pool in there which worked ok but took forever to fill and had some issues. I feel it would b easier to just stand in the shower with her but I've only rinsed her that way, never washed hair or anything.

How do people do it?
