Nestled in between the museum formerly known as MOMA, and the African Diaspora Museum, the St. Regis is a swinging spot with fantastic people watching. The bathrooms feature a sleek and modern design, with floor to ceiling doors on the private stalls. Sit and stay awhile. Pee to your heart’s content.

Ladies, you’re in luck at the Four Seasons with complimentary feminine sanitary napkins. There's plenty of stalls to go around, but give give yourself time to get through the elevator ride from the lobby (no emergencies here). Still, it beats using the public bathrooms at the nearby Westfield mall.

We were impressed with the complimentary scented hand lotion available at the Mark Hopkinss, and the moody dimmed lighting. The only downside is that these stalls are all open air -- not the closed off private rooms found at the other hotels on this list. But we’ll deal with the sharing of air space in exchange for free hand lotion any day.

It doesn’t get much classier than the Ritz Carleton, and we love this historical building's neo-classical design and opulent details. It'd be great if that taste of luxury extended to the public bathrooms, which are clean and pretty but a bit plain.

Hotel Adagio was recently revamped, and it's a treat to experience the results on your way in and out of the facilities. Take some time to enjoy the industrial pop playing in the swanky lobby. Our only warning is the options are limited for the men -- only one urinal and one stall, fellas.

The Fairmont is one of San Francisco's most luxurious hotels, and the turn-of-the-century opulent charm extends from the lobby into the public bathrooms, consisting of vanities, waiting room, and private stalls galore.
