Get a cup or a small container from somewhere in there (if she's ok with you running to get it) and let her/help her use it to pour the water over her head instead. She won't have to dunk her head that way, but she can still get clean.

Shit, that’s a good idea.
Lana: “How about I get a cup and I can carefully pour some water on ya? I’ll be nice and gentle.”

Kaari: “Eh-ah…yeah, we can try that. Just…knock before coming back in.”

I make a quick trip into the kitchen and-ugh. Please tell me I have clean cups. Please tell me I – YES!

The last cup in the cupboard!

Eugh, yet another thing to clean up later.
