18 Gauge Premium Grade Stainless Steel Finish: Polished Stainless Steel Drain: 2″ Contemporary Design Shower drain base not included but is required and available as model # ABDB55. This linear drain does not include a cover. This provides you with the opportunity to install a tile over the drain, matching the remainder of your shower design and offering the appearance of a concealed drain. In order to maximize water drainage, instillation requires that the shower floor include a slight slant towards the direction of the drain. See installation instructions for further details.
