Bought this for a complete bathroom renovation for my mother-in-law. It is absolutely beautiful, and so much more modern and clean than the sliders she had previously.  The door spans approximately 3/4 of the tub, and can be opened both in and out. My mother-in-law loves the product, as it allows the beauty of the tile to shine through. The installer cracked the tile the first time trying to drill the brackets in place, but now that the tile is repaired and the door is up it looks great.
