A highly transparent real glass sliding door design for a shower enclosure with floor-level comfort walk-in provides more safety than a swinging construction. It also saves useful space. The highly transparent glass door disappears almost completely behind the fixed segment. The construction dispenses with the upper guide rail, which enhances the high-quality overall appearance and still ensures overall splash protection. The puristic door handle is mounted on the very edge of the glass surface. Thus, the door can be opened and closed easily both from inside and outside. The optional anti-plaque glass treatment allows easy cleaning.
