Sutro Baths and visitors. Adolph Sutro, the self-made millionaire who designed Sutro Heights and later the second Cliff House, developed the Sutro Baths in 1894. He constructed an ocean pool aquarium among the rocks north of the Cliff House. Sutro then expanded his ocean front complex by constructing a massive public bathhouse that covered three acres and boasted impressive engineering and artistic details.
