The London Hammam was the first public Turkish bath erected in this country, and owes its existence to the fervid zeal of the late David Urquhart. It was erected in 1862, from the designs of the late Somers Clarke. The bath rooms proper are modelled on the Eastern plan, and have quite an Oriental effect, with the stars of stained glass sparkling in the sombre domed tepidarium. In this bath the office is arranged in the old building in Jermyn Street, adjoining which is the combined frigidarium and apodyterium, a structure of wood, originally intended as a temporary building only. This is covered with an open-timbered roof, and divided into nave and aisles by cut-wood posts, and lighted by a clerestory. These posts form the divisions of the divans, which are separated from one another by ornamented wood partitions worked in an Eastern manner. Connected by double doors with this apartment are the hot rooms. The main room--a very moderately-heated tepidarium--is a square on plan, with splayed angles, over which rises a dome of brickwork. On either side of this square, and connected with it by the horseshoe arches supporting the dome, are transept-like apartments, used as portions of the tepidarium, similar adjuncts existing at the ends and joining on the one hand the frigidarium, and on the other a heated smoking saloon, which occupies a position corresponding to that of a Lady-chapel in this very ecclesiastical-looking plan. On either side of this saloon are two calidaria. A drying room and laundry are arranged over the smoking saloon, and w.c.'s, &c., are placed at the end of the latter apartment. In the splayed angles supporting the dome are doors leading to four apartments--two used as hot rooms of different temperatures, and the others as a washing-room and a shampooer's waiting room. Under the dome there is an extensive platform of marble slabs, beneath which is the douche room, reached by a short flight of steps. The plunge bath is placed, partly in the tepidarium, and partly in the frigidarium, with an arrangement to prevent the transmission of the hot air, such as I have herein before explained. In the centre of the frigidarium is a little marble fountain. One of the divans is partitioned off for the accommodation of the chiropodist. A gallery is provided for the hairdresser, and connected with a shop in Jermyn Street. The ground sloping considerably, a descent of a few steps has to be made to reach the frigidarium from the street. A refreshment bar is placed in the frigidarium. The manager's room is on the second floor, adjoining the old building, and has a window overlooking the frigidarium.
