Sterling 60" 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. 72132100-0 (SKU 443407), end walls model No. 72105100-0 (SKU 443381); for Sterling's curved walls use back wall model No. 72232100-0 (SKU 443791), for end walls use model No. 72205100-0 (SKU 404887). When used with our wall sets the finished shower unit is 60" x 34" x 75-3/4" tall. Sterling Vikrell shower systems assemble with a tongue and groove system that minimizes the need for caulk. Use Sterling doors model No. 5475-59S-G05 (SKU 443443), 5475-59N-G05 (SKU 443452), and 5976SP-59S (SKU 452735). Sterling Vikrell fixtures are backed by a 10 year consumer warranty.
