A wall installation connection box unit including 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 space is accessible via an open front end face of the sleeve portion, a functional surface body including a functional surface, and a connection device which is configured for releasable fastening of the functional surface body to the base portion in different axial levels of the functional surface and includes at least one connection structure on the base portion radially outside the sleeve portion and a connection body cooperating with the connection structure, which connection body is user-operable via an actuation interface to be movable relative to the connection structure and to the functional surface body between a released position and a fastened position. Illustratively, the actuation interface of the connection body is located on a side of the functional surface body facing away from the base portion of the box housing body or the actuation interface, or the connection body is rotatable between the released position and the fastened position, or the connection device is configured for selective releasable fastening of the functional surface body in front of a front side or behind a rear side of the base portion of the box housing body.

A wall installation connection box unit, including 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 an installation component mounting space, which space is accessible via an open front end face of the sleeve portion, an extension sleeve which is configured for coaxial arrangement on the sleeve portion and axial pushing back relative to the sleeve portion, and a retaining structure which allows axial pushing back of the extension sleeve on the sleeve portion from a mounting position to an end use position on variable axial level and retains the extension sleeve in the end use position on the sleeve portion. Illustratively, the retaining structure includes a retaining ridge structure radially projecting from the sleeve portion, which is formed integrally with at least one adjacent axial partial region of the sleeve portion from a sealing resilient material, and a counter-retaining structure cooperating with the retaining ridge structure in a frictionally engaged and/or form-locking manner, provided on the extension sleeve and made from a material which has greater stiffness as compared to the sealing resilient material. In addition or as an alternative, the wall installation connection box unit includes a spacer element which is attachable to the box housing body in a securing position in a detachable manner, where the spacer element secures the extension sleeve in the mounting position against axial pushing back.

A sanitary wall installation connection box unit, including a box housing body having a rear-side base portion and a sleeve portion projecting to the front from the base portion, which sleeve portion peripherally surrounds a sanitary component mounting space, which 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 includes 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. Illustratively, 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, and 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 connection region of the base portion.

A wall installation connection box unit, including a box housing body having a rear-side base portion and a sleeve portion projecting forward from the base portion, and a connector body disposed on the base portion. The sleeve portion peripherally surrounds an installation component mounting space, which space is accessible via an open front end face of the sleeve portion. The connector body includes an installation component connection contour facing the installation component mounting space and a conduit connection interface structure accessible on an outer side of the box housing body. Illustratively, the sleeve portion and the base portion of the box housing body are integrally formed from a synthetic foamed material, and the connector body is embedded in the synthetic foamed material of the base portion, wherein the conduit connection interface structure and the installation component connection contour are exposed.

A pull-out hose guiding device for guiding a pull-out hose having at least one hose bend of variable hose bend length, wherein the pull-out hose guiding device includes a hose guiding box configured for accommodating the hose bend in an anti-twist manner in a box-inwards hanging position, and a guide weight roller arrangement including at least one guide weight roller which is insertable into a bend reversion zone of the hose bend for rotary motion about a roller rotational axis. The guide weight roller with its roller rotational axis is capable of translational motion in a hose bend lengthwise direction box-outwards with decreasing hose bend length and box-inwards with increasing hose bend length. A sanitary shower device may be equipped with such a pull-out hose guiding device.
