Structure Baidu

While most tubs have swing-in doors, that is, doors which swing into the tub for entry, some have swing-out doors for easier access. While the swing-out doors can make the tub easier to enter, it also brings the possibility of flooding should the door not be latched properly. If not secured properly, the weight of the water in a filling tub could cause the door to open and dozens of gallons of water to spill out into your home. While doors are also water sealed, there is always the chance of a seal failure that could also lead to leaks or flooding.
Because a walk-in tub has a door in the side of the tub itself, you cannot add or drain water while the door is open. This means you’ll spend a considerable amount of time sitting in the tub while waiting for it to fill as well as time waiting for it to drain before you can exit the tub.
