A bathroom feature that is already common in hotel rooms are glass bathroom doors, which are just as hated.
But it seems some hotels are going even further - and getting rid of doors entirely.
Experts have said this is common in cities such as London and Tokyo when hotel space is tight, meaning rooms are often smaller.
By ditching the doors, it makes a bedroom seem larger and trendier.
Kenneth Cronin, who has worked as a project coordinator for hotels, told Thrillist: "The key lies in thoughtful design and careful consideration of sight lines, which are the views extending beyond a space’s immediate confines.
"For instance, the view from a corridor when a bedroom door opens or the placement of a mirror that might reflect a private area.”
This was backed up by interiors supplier Drench last year.
They told Sydney Morning Herald: "The lack of dividing walls means that natural lighting can fill the room and the panoramic views can be fully appreciated.
"If well-designed, the close proximity can make the bedroom-bathroom areas feel much more spacious than they actually are."
