The FN-R21 is a frameless double sliding fluted glass shower door built for distributors, private-label brands, and project buyers who need consistent quality at volume. Manufactured directly by SANIKB, it pairs 3/8" (10mm) fluted tempered glass with a 304 stainless steel bypass system, with custom sizing and three hardware finishes to fit a wide range of U.S. projects and product lines.

The reeded glass surface diffuses light while adding visual privacy, which makes it a practical fit for residential renovations as well as multifamily and hospitality bathrooms. The vertical fluting runs the full panel height, and the 10mm tempered construction delivers the strength and safety performance buyers expect from a frameless enclosure. The double sliding (bypass) design opens from either side, suiting wider openings without the swing clearance a hinged door requires.
