Hoyles Igsfbkit Basic Shared Bathroom Kit. Sharing one bathroom between two bedrooms can save an entire bathroom worth of floor space plus the cost of the sanitary ware, maintenance and cleaning. By sharing a single facility between two rooms or areas better facilities can be provided in less space and at a reduced cost. Suited to domestic and commercial applications, our Basic Shared Bathroom Solution provides an electronic means of locking two doors of a shared bathroom at the press of a single button. It provides LED indication of the door lock status to the user. The system ensures that one user cannot vacate the bathroom leaving another users door locked as they could if using mechanical locks. What the basic system does not prevent is persons using the bathroom to pass from one room to another, if this is requirement for your installation, please see our Advanced System.
