The ladies' baths partly adjoin the gentlemen's, and are partly separated by an area. They are entered from the side street. On the ground floor is the pay-office and cooling room. Additional couches are provided on the first floor, where is also an attendants' room. In the basement are three hot rooms and two shampooing rooms. A washing room, shower bath, and plunge bath adjoin the shampooing rooms. The hottest rooms of both sets of these baths are within a few feet of each other. Each, however, has its separate and distinct furnace. A passage formed by the area allows access to the stokery and furnace chambers. In Messrs. Nevill's baths at London Bridge the cooling rooms, &c., are in the basement, and the bath rooms proper in a sub-basement. Bartholomew's baths at Leicester Square are an excellent example of a compactly-arranged double set of baths. The various apartments are designed one above the other on different floors, the area of the building being limited. On the ground floor, as usual, are the pay office and a combined cooling and dressing room, and an attendant's room. In the basement are the bath rooms, arranged _en suite_--first a shampooing and washing room, containing, also, in a very compact manner, the plunge and shower baths; next is the tepidarium; then the smaller second hot room; and, lastly, the smallest hot room of a very high temperature. The heating chamber is placed adjoining this. The principle of its construction is that generally adopted in the baths erected under the late Mr. Bartholomew's direction, viz. a furnace with a coil of thin iron flue-pipes, radiating, in a measure, a certain amount of heat directly into the hot rooms. The bath rooms are divided from one another by glazed wood partitions, as distinct from the solid walls dividing baths like the Hammam and Savoy. A consideration of these two methods of dividing the hot rooms, does not, however, concern us here. A staircase from the entrance vestibule leads to the ladies' baths on the second and third floors, where also are manager's and other private rooms. Broadly speaking, baths may be divided into two classes, viz. those in which the various apartments are arranged _en suite_, and those irregularly planned. Where possible the former arrangement is preferable, as, with the hot rooms in a line, the circulation of air is facilitated. Fig. 11 is a section of a set of hot rooms arranged _en suite_; and the baths at Figs. 24 and 25, in Chapter VIII., are planned on this principle.
