The door locks automatically when it is slid shut and the handle must be lifted to slide the door open. As an added safety precaution, the seal puts pressure on the side of the tub when there is water in the tub. The more water there is in the bathtub, the harder it is to open the door. The pressure on the seal locks it in place. It is possible to force open the door with water in it, but unlikely that someone would do it accidentally. It would take over 50 lbs of force to overcome the pressure seal compared to 2 lbs of pressure to open the door when the tub is empty.
