"Give your bathroom a modern, spa-like upgrade with this frameless sliding shower door in matte black stainless steel and crystal-clear 5/16"" (8mm) SGCC-certified tempered glass that resists shattering and stays bright and easy to clean. The adjustable design fits 56""-60"" openings and assembles to 60"" L x 0.5"" W x 76"" H, installs left or right, and features a stainless steel top guide rod and structural hardware built to resist rust and heavy use. Advanced waterproof sealing with side strips stops splashes and mist so your bathroom stays dry while the sleek handle doubles as a handy towel rack for modern convenience. Assembly is straightforward with clear instructions but professional installation is recommended for the best performance and long-lasting, leak-free use."
