Sterling 48″ x 34″ Ensemble white shower bases are made of Sterling’s exclusive Vikrell material with high-gloss finish. Vikrell is a sheet molded compound that is solid color throughout, and stronger than fiberglass. The base features a lightly pebbled slip-resistant bottom for safer footing. Drain not included. These bases can be used with tiled-in applications, or with the Sterling Ensemble back wall and end walls. For Sterling’s simulated tile walls use back wall model No. 72122100-0 and end walls model No. 72105100-0; for Sterling’s curved walls use back wall model No. 72222100-0 and end walls use model No. 72205100-0. When used with our wall sets the finished shower unit is 48″ x 34″ x 75-3/4″ tall. Sterling Vikrell shower systems assemble with a tongue and groove system that minimizes the need for caulk.
