Question! Help a mama out

I have a 19 month old who officially started walking on his own about two weeks ago. He's been soo curious, doesn't stop at all and trys to get into anything. How do I shower when I'm home alone with him? (dad works early) can't do it at night because it wakes him up and during the day can't be in his crib without throwing a tantrum. Idk how to do it anymore.
