Sterling Ensemble 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. When used with our wall sets the finished shower unit is 75-3/4 In. tall. Sterling Vikrell shower systems assemble with a tongue and groove system that minimizes the need for caulk. For Sterling doors see Related Items. Sterling Vikrell fixtures are backed by a 10 year consumer warranty. Shower base only - wall set not included.
