Sterling adds a new nature-inspired design to its line of Deluxe By-Pass Shower Doors: Birchwood. This design incorporates images of slender birch trees silhouetted against a precise field of dots. It is a mix of geometric and organic forms that takes on a different look with each new angle. For added options at the time of installation, both the top track and the towel bar are reversible with a different aesthetic on either side. The door is available with nickel or silver framing finishes.
