Sliding, or bypass, shower doors are on a single track and slide from side to side to allow entry into your shower. These are a popular design that incorporates a fixed panel and a sliding panel. The sliding panel sits on rollers within a track and slides behind the fixed panel to allow access. Since the door has to slide behind the fixed panel the minimum size of a sliding door is usually 1000mm. Buy sliding shower doors online at best quality bathrooms online store, England UK!
