The Bath building stands somewhat north of the new Cliff House, and its entrance from Point Lobos Avenue is a small classic temple.
From this, by broad stairways, flanked with shrubs and flowers, the Museum gallery is reached. Here are placed the archaeological and other collections of Mr Sutro.
Mummies and innumerable other curiosities from ancient Egypt, a goodly number of specimens of Aztec pottery and art that show a curious resemblance to the work from the land of the Nile, beautiful fans from various countries, Damascened plates, Chinese and Japanese swords, wooden ware used by the North American Indians, totems from Alaska, etc., etc..
In the Bath galleries proper will be found a superb collection of birds and animals, scenes from Japanese life, portfolios of photographs, and valuable state papers, oil paintings, and hundreds of other works of art and curios.
From the Museum gallery, the visitor can reach the Baths, either by stairways or by the elevator.
The swimming baths
Striking as is the first view, familiarity only makes it more striking. Its size seizes the imagination, yet it is not oppressive, owing to the lightness and airiness of the structure. Sitting on a rock, watching the waves of the Pacific, dreaming of a way to utilize the gigantic power of the sea, part of this whilom dream of Sutro’s is here turned into reality.
Tier upon tier rise seats, while at their base, visible to everyone, are the swimming tanks. The sea water is supplied by an ingenious use of the ocean waves. A basin scooped out of solid rock receives the water that dashes over the top, thence it is conducted to a settling tank, from which by numerous small canals it makes its way into the various tanks. Of these there are six in all; the largest one will contain the sea water in its normal state; the others will be heated to different temperatures to suit the varying requirements of visitors.
As stated above, the Baths are filled by the ocean itself. Should, however, there be tides so low as to necessitate pumping, preparations therefor have been made, and the water can be forced in at the rate of 6,000 gallons a minute.
The mere emptying of the tanks entails no difficulty; but the emptying of them in such a way as to prevent the return of the once-used water required ingenuity. The refuse water in the main outlet, into which all the tanks ultimately empty, is piped hundreds of feet to the other side of the headlands, thence passes into the tidal current and away from the Baths.

The kitchen, 30×50 feet, contains four large ranges, broiler, stock kettle, warmer, etc., and can provide easily for the wants of 6,000 visitors. The Baths are lighted by electricity, two 800 candle-power arc lights and a number of 25 candle-power lights.
Viewing areas of the Sutro Baths swimming pools
All of the Sutro Baths buildings are protected on the west side by an enormous breakwater, 400 feet long, 20 feet deep, 25 feet wide at the top and 75 feet wide at the base, that contains 450,000 cubic feet of rock. There is also another breakwater running east and west, 300 feet long, 25 feet wide at the top, 75 feet wide at the base, and. 20 feet deep, and contains 300,000 cubic feet of rock.
These two breakwaters furnish security against any possible contingency of a stormy sea. Indeed, there has been nothing omitted in the construction of the vast building or in its thousand details that could give security or add comfort to the visitor within its gates.
