Antique Combination Soap Tray and Grab Bar.  Classic porcelain enamel and cast-iron construction.  Timeless design appropriate for any vintage inspired bathroom.   

Condition:  Antique used, solid.  Paint wear, paint chipping, surface rust, discoloration.  I pushed hard upon the rusted area and scraped it hard with my fingernail - it feels like surface rust and still very solid.   I didn't see any holes or cracks that threatened its structural integrity.  New owner would likely want to sand and touch up this area before installation to ensure another century of service.  Remnant cement on rear.  

Dimensions:  Please refer to photos.  Approximately 6.75" square.   Depth (portion in wall) approximately 1 7/8".  Depth (portion outside wall) about 3".
