Abstract: A concealed shower drain assembly for placement at the bottom of a shower wall has a rigid vertical flange continuously joined in fixed orientation along one side of a rigid horizontal deck member. An opening in the vertical flange leads to a sealed drain box on behind the flange. A drain pipe at the bottom of the drain box provides egress of waste shower water from the drain box. A removable access panel is supported from the vertical flange a plurality of support posts affixed to the interior wall of the drain box. A gap between the periphery of the access panel and the sides of the opening in the vertical flange provides a flow path for shower waste water into the drain box. The drain assembly can be securely attached in place in a shower stall by nailing or screwing the rigid vertical flange directly to the framing of the shower stall.
