This bath/shower surround is made of Vikrell, a
solid composite material comprised of resins, fiberglass, and filler, exclusive to Kohler. The material has earned GREENGUARD Gold Certification,
which helps buyers identify products and materials that have low chemical emissions and improve air quality. Compression molded panels interlock, and hang directly on studs—no caulk required. The color of this durable material is solid throughout, and
won’t chip or stain.
