Abstract: Interior construction system for a sanitary area which has plate-shaped wall elements made of glass. The wall elements can be either straight or curved into a radius. The wall elements are connected positively and non-positively to a load-bearing element or stay pipe. Fastening locators on the stay pipe pass through a boring in the wall element and secure the wall element by the use of a fastener on the end of the fastening locator. A panel profile is attached to the stay pipe to conceal the joint formed by the wall elements. The panel profile has an enlarged cross-section at the end of its legs wherein a gasket resides in a groove and forms a seal at the wall elements. The interior construction system for a sanitary area has glass wall elements which are attached to stay pipes at differing angles. The joints of the wall elements on the stay pipes are hidden and sealed by panel profiles which are attached to the stay pipes.
