Visign M4 appears as an integrative technical and formative element in the relaxation area bath tub. Affected by technical quality, the completely new feature reduces the structure height of Visign M4 to a minimum and extends the activity room in the tub considerably. Especially the combined overflow and outflow is corresponding with each other and complements the modern, plain formative language of architecture and design reticently, but self-confident. The foldout handle element confirms simple basic geometry and allows for a save use in each situation.
