As early as the 1980s, a study by the architecture professor Roger Ulrich showed the effect of a pleasant spatial environment on the healing process. As a result, patients needed far fewer painkillers, suffered less depression and could be discharged earlier.

The concept of “Healing Architecture” was derived from these findings, the healing architecture of medical facilities and its influence on the physical and mental well-being of patients. More and more operators and planners of those buildings are therefore relying on this "Healing Architecture". Illustrative examples of this are the Eisenberg Waldkliniken in Thuringia and the Blomenburg private clinic in northern Germany, where complete bathroom equipment from Keuco were used.

In terms of the quality of stay, the Waldkliniken in Eisenberg correspond to a five-star hotel. High-quality rooms, designed in soft, natural colors, exude calm and cosiness. In the bathrooms, a decision was made in favor of a complete Keuco bathroom equipment so that everything fits together perfectly: from fittings and accessories to light and cosmetic mirrors to washbasins and vanity boards. The Ixmo fittings in the shower and on the washstand are one-offs that have been provided with the Eisenberg logo, an oak leaf. In addition, the round floor plan of the new building enables each patient to look out into nature from his or her bed - a central aspect of the design by the architect Matteo Thun, which the patients of all health insurance companies (among the 246 patient beds there are "only" 13 for private patients) are able to enjoy.

The private clinic Blomenburg, built in the 19th century, whose therapy and design concept stands for holism, is a place of retreat in the midst of the most beautiful surroundings in the north of Germany and is itself surrounded by an extensive park. It offers 69 spacious, high-quality single rooms and suites. There guests can devote themselves to mental regeneration in a quiet and peaceful stylish ambience, while noble materials and attractive furnishings in the guest rooms create the ideal setting for rest and relaxation. The modern bathrooms were equipped with the X-LINE bathroom furnishings from Keuco in a soft natural tone, which, in addition to the vanity unit and the tall cabinet with shelf arranged on the side, offer a light mirror with a frame as a storage area. The integrated mirror heating ensures a fog-free look in the mirror, even after a hot, relaxing shower. Windowless bathrooms are also equipped in this way to create bright, friendly rooms and guests are offered enough storage space for their personal care products in their temporary home.

A high quality of stay does not only benefit the patients, but the architectural design also has an impact on the medical and nursing staff. An increased quality of stay, which is optimally coordinated with the requirements for hygiene, medical processes and building security, improves working conditions and lowers the level of illness among staff. And if the staff feels comfortable in the workplace, this in turn influences the well-being of the patients and relatives.
