Any good Northern California clothing-required hot springs / public baths?

First off, I’m pro-nudity and I myself would smirk at this question. But are there places to go if someone is uncomfortable with nudity (themselves or others)?

Places similar to Kabuki in SF (except Tuesdays, I know), Orr hot springs, Wilbur, Harbin, etc. I’m more interested in bigger ones like those than small ones like Sweetwater in Mendocino, but will take any suggestions.

It’d be nice to have a personal recommendation to somewhere you’ve been.
