a box housing body having a rear-side base portion and a sleeve portion projecting forward from the base portion, which sleeve portion peripherally surrounds a sanitary component mounting space, which sanitary component mounting space is accessible via an open front end face of the sleeve portion; and
a connector body disposed on the base portion of the box housing body, which connector body comprises a sanitary component connection contour facing the sanitary component mounting space, a fluid line connection interface structure accessible on an outer side of the box housing body, a fluid conduit structure for fluid connection of the fluid line connection interface structure to the sanitary component connection contour, and at least one electric line feed-through opening leading from an outer side of the connector body through the connector body to the sanitary component mounting space;
wherein:
the base portion of the box housing body is made of a sealing resilient material at least in an electric line connection region adjacent to the electric line feed-through opening of the connector body;
the electric line feed-through opening of the connector body is covered on an outer side by a closure membrane made of the sealing resilient material of the electric line feed-through region of the base portion; and
the base portion of the box housing body in the electric line connection region has an outside, blind hole-shaped tube insertion port opening in the sealing resilient material, wherein the tube insertion port opening in a longitudinal direction overlaps with the electric line feed-through opening of the connector body, and wherein the closure membrane forms a bottom region of the tube insertion port opening.
