Aalto's starting point for the design of the sanatorium was to make the building itself a contributor to the healing process. He liked to call the building a "medical instrument". For instance, particular attention was paid to the design of the patient bedrooms: these generally held two patients, each with his or her own cupboard and washbasin. Aalto designed special non-splash basins, so that the patient would not disturb the other while washing. The patients spent many hours lying down, and thus Aalto placed the lamps in the room out of the patients line of vision and painted the ceiling a relaxing dark green so as to avoid glare. Each patient had their own specially designed cupboard, fixed to the wall and off the floor so as to aid in cleaning beneath it.
