The Perform Broadway Acoustic Style Waterproof Shower Panel is exactly that. These panels look like acoustic panels with the shadow gap but aren't on a foam backing, making them 100% waterproof and the ideal feature panel that is designed to be in contact with water. The panel is 2400mm high, 600mm wide (face 598mm), 11mm thick, and the backing is 5 layers of ply with a thicker laminate face, as the shadow line has been etched, giving the touch of real tiles.
