Our bathtub, was installed, at a slight tilt. It is tilted from back to front. The sliding door, even with adjustments, most of the time slides open. We have jimmied an object between the doors to stop the sliding. Also, there is a slight leak at the front of the bathtub (Where the front vertical panel meets the bathtub). The leak if not sealed will leak into the walls. The tilt is not that bad.
