In the generality of modern baths, the frigidarium forms also the apodyterium. This arrangement is economical of space, and has been found, in practice, the most convenient for bathers; but there is much to be said in favour of a separate and distinct cooling room, such as that at the Camden Town Turkish Baths. Erected from the designs of Mr. H. H. Bridgman, F.R.I.B.A., these baths are specially noteworthy for their spacious frigidarium and ample plunge bath. Entering from the street, a corridor conducts to a short flight of stairs leading to the office. Adjoining this is an apodyterium, fitted with two ranges of dressing-boxes, one above the other, a gallery forming the floor of the upper tier. From hence a short staircase leads to the door of the tepidarium, at right angles to which is the calidarium. Adjoining the tepidarium is a combined shampooing and washing room, a door in which opens into a chamber containing a plunge bath of quite exceptional dimensions. A staircase leads to the door of the lofty and spacious cooling room. This is lighted from the top, and contains a fireplace, a feature usually omitted in cooling rooms, and really superfluous, though adding greatly to cheerfulness of aspect in the winter. From this frigidarium the bather can return to his dressing-box by way of a lobby. Thus he makes a complete round, and does not meet the incoming bathers on the staircase to the tepidarium. The latest built elaborate commercial baths in London are those of Messrs. Nevill in Northumberland Avenue (Fig. 2). They were designed by Mr. Robert Walker, F.R.I.B.A., and comprise both ladies' and gentlemen's baths, though, as at the old Pompeian _Balneæ_, the former set are ungallantly cramped into a very small space. They occupy a corner site, and the entrance to the gentlemen's bath is formed at the rounded angle. In the vestibule is the usual cashier's office, and provision for hats and coats. From the vestibule the combined cooling and dressing room is entered, after passing the boot room on the left and the refreshment bar on the right. Between the boot room and the staircase is the hairdresser's room. Dwarf wooden partitions divide the cooling room. Off a landing on the staircase are a lavatory and w.c.'s and toilet-table. The staircase leads to the first floor--where are provided extra couches--and to the bath rooms in the basement. The first floor is practically a gallery. In the basement are three hot rooms, the tepidarium being an elegant apartment elaborately adorned with marbles and rich faïence. A heated smoking room adjoins the second hot room. There are in this bath three shampooing rooms--an arrangement conducing greatly to privacy. A douche room and plunge bath are provided in the angle of the building. Vaults under the street are utilised as a laundry, attendants' room, meter room, and engineer's shop, and as store-rooms. [Illustration: FIG. 2. Turkish Baths, Northumberland Avenue, Charing Cross.]
