Since the revival of the bath of antiquity, and its introduction into this country under the name of the Turkish bath, this method of bathing has become very generally adopted; and although onward progress is rendered less rapid than it might be, by the wide-spread popular ignorance that ascribes an element of danger to the bath, erroneous impressions are being gradually removed, and the continual building of new baths testifies to the manner in which the institution flourishes on British soil.

To what extent the delusion concerning the supposed danger connected with this form of bathing is to be ascribed to popular ignorance and prejudice, or to the fact that baths of unsuitable design and construction, and of faulty heating and ventilation, are put before the public, it would be hard to say. Certain it is that the latter cause has done much—very much—injury.

I cannot but think that one of the chief obstacles to the progress of the bath in this country, is that little or nothing has been written or said about its proper design, construction, and working, and that no full inquiry has been made into the best possible method of supplying heat to the bathers. As a consequence, we have had, and still have, placed before the public, and meeting with undeserved success, "Turkish baths" which are such only in name—unhealthy, ill-ventilated cellars, where the air, deteriorated at the outset by the heating apparatus, stagnates in the sudatory chambers, and becomes loaded with the exhalations and emanations of the bathers, and not unfrequently charged with a nauseating and disgusting odour. What wonder that we so often hear persons remark that they have tried the bath, but neither enjoyed it nor did it agree with them! The damaging effect of "baths" of this type on the prospects of the true bath is incalculable.

In the absence of enlightenment, however, thousands, convinced of the value and benefit of the bathing, periodically attend these miserable substitutes for properly-planned, hygienically-heated, and effectively-ventilated Turkish baths. Viewing any self-evident shortcomings as irremediable evils, ignorant of the true principles of bath construction, and knowing little or nothing of the physiological action of the bath, they have neither the means of ascertaining, nor the power to detect, the genuine article from the harmful substitute. With the public the best bath will be the most elaborate and most flashily decorated, and the moth-and-candle principle comes into play with striking semblance to the original type.

So much has been written and said about the arrangement, design, and working of the baths of the ancient Romans, and of the Oriental nations of to-day, that it will be superfluous and unnecessary here to enter upon the subject, fascinating though it be to any one interested in the building of modern baths. An intelligent study of old plans, and of the writings of those who have given their attention to the elucidation of the special purposes to which the various apartments of the Roman ThermÆ were devoted, serves in no small degree to a complete understanding of the problems involved in the perfecting of the bath in modern times. So also with regard to the Hammam of the East, an acquaintance with its plan and working is equally instructive. But to fully elucidate the history of thermo-therapeutic architecture would require a volume of itself, since the many questions that present themselves to the student of ancient baths cannot be properly understood without considerable and lengthy description. Those desirous of studying the subject of the design of ancient and Oriental baths will find many works within easy reach. In his 'Manual of the Turkish Bath,' the late David Urquhart has given a most complete account of Eastern baths; and in Sir Erasmus Wilson's 'Eastern or Turkish Bath,' will be found a popular account of the sumptuous baths of antiquity, which will serve as an introduction to further researches with the aid of more abstruse works, such as Wollaston's 'ThermÆ Romano-BritannicÆ,' Cameron's 'Baths of the Romans,' and particularly the careful description of the Pompeian BalneÆ in Sir William Gell's 'Pompeiana.' In the admirable works of Samuel Lysons, the Gloucestershire antiquary, will be found interesting accounts of the remains of old Roman baths in this country; and in Daremberg and Saglio's 'Dictionnaire des AntiquitÉs Grecques et Romaines,' is a most capable essay on ancient BalneÆ. In Eastern travellers' books, desultory descriptions of the Oriental bath will be found; and in Owen Jones's work on the Palace of the Alhambra, at Granada, plans and sections are given of the elegant little bath that the Moorish builders erected therein.

For the purposes of this work, and for the sake of brevity and convenience, I have thought fit to adopt the following terms from the old Roman vocabulary, to designate the apartments of the modern bath. I respectively term the first, second, and third hot rooms, the Tepidarium, Calidarium, and Laconicum. Although the exact nature of the ancient Roman laconicum is still a question in debate, I have chosen to employ the term to designate herein the hottest of the hot. The washing room I call the Lavatorium; the cooling room, the Frigidarium; and the separate dressing room, the Apodyterium.

The modern "Turkish bath" is rather a revival of the Roman bath, than that of the East. Among the Orientals, the air of the sudorific chambers is charged more or less heavily with vapour. In the ancient Roman bath, the atmosphere must have been more or less dry. And it has been decided by physiologists and physicians of the hydropathic school, that the air of the bath cannot be too free of all moisture. With a perfectly dry atmosphere a high degree of heat can be borne, and the dryness moreover is conducive to perspiration. This absolute need for a dry atmosphere in the bath will be found fully explained in an admirable work by Dr. W.B. Hunter, M.D., entitled 'The Turkish Bath: its Uses and Abuses.' But notwithstanding the fact that the type of bath employed at the present day resembles, in point of dryness of atmosphere, that of ancient Rome, the name of Turkish bath, originally given to it by Mr. Urquhart, has held good, and must now be accepted as the correct modern designation.

Neither the term "Turkish," however, nor the designation "hot-air" bath, convey to the uninitiated any idea of the true principle of "the bath," as I shall hereinafter call it for brevity's sake. More properly it is a "heat bath"—a thermal cure. In the ordinary hot-air bath, the heated air is simply a medium; and, as I have endeavoured to explain in the body of this little work, the heat is best supplied to the body of the bather by direct radiation. By the "Turkish bath," therefore, I would be understood to mean a method of supplying pure heat—not necessarily hot air—to the surface of the human body for hygienic, remedial, and curative purposes.[1]

In the following pages, however, I have, in this respect, treated of the subject from the broadest point of view, and have explained the method of designing the hot-air bath pure and simple, looking upon the convected and radiating heat principles as both good of their kind, and perfectly admissible modes of applying heat to the human frame. I have adhered to this plan throughout, because, even supposing that it were shown conclusively to-morrow, that the principle of heating by convection is absolutely wrong, baths of this type would, owing to the slow march of improvement in this country, still be built and require to be planned. Moreover, it has been in the past, and still is, the generally accepted idea that the Turkish bath is a hot-air bath pure and simple.

Medical men of eminence who have studied the question have thought fit to retain the term "hot air" in descriptions of the Turkish bath. In deference to their opinion I may hereinafter, in places, speak of the hot-air bath. The arguments put forward in favour of radiant heat, with a comparatively cool atmosphere, in the sudorific chambers, are, for the most part, the result of my own experience and study.

I treat of my subject in two sections, dealing with public and private baths respectively. Chapters II. to VII. are devoted to the elucidation of the principles to be observed in the building of public baths, either for true public purposes or as commercial speculations. It is unnecessary to speak of these two classes of baths under separate heads: what is required of the one is required of the other. The only difference is that one is the property of the people, and may be required to be designed in a block of buildings containing other kinds of baths; and the other is owned by a company of persons or by a single individual as the case may be, and is generally an establishment complete in itself.

It is not to the credit of the English nation that so little has been done in connection with Turkish bath building for the people. The attention given to the question of supplying bath-houses of any kind is of the most meagre character. The provisions of the Public Baths and Wash-houses Act are entirely inadequate. In these matters the German nation is far ahead of us. Fortunately for the general health, the Englishman is renowned for his morning "tub." But the cold tub is merely a tonic bath, and the Turkish bath cleanses both the inward and outward man, besides constituting a most perfect tonic. The cleanliness of the vast body of the English depends on the warm shallow bath, an ineffective means at the best, and, often, when taken at a high temperature, fraught with a real danger to certain constitutions. Used, as customary, without a tonic application of cold water, it is eminently conducive to cold-catching. But one cannot blame the average Englishman for his neglect of the health-giving habit of scientific bathing, unless he sees the advantage of, and has means to afford, a Turkish bath in his own house. He looks in vain for an appropriate, comfortable, and attractive bath-house provided for him by the Legislature, and he dislikes the thought of the impure atmosphere and odours of the so-called "Turkish baths" provided by enterprising business men. He can do nothing but fall back on his warm water bath and cold morning tub.

In the second section, comprised in Chapters VIII. to X., I have dealt with private baths, including the bath in the house and mansion, in institutions of one kind and another, and in connection with training stables. In the chapter on the bath in the private house, will be found plans of baths of several types, from the smallest and least expensive to the most elaborate and costly.

It is my hope that this little work may lead to some attention being bestowed on the question of providing public Turkish baths worthy of the country; that it may add a stimulus to the building of high-class baths as commercial speculations; and that, from its pages, those desirous of experiencing the luxury of a model Turkish bath in their own homes, may learn the best methods of its design and construction.
