Have porthole doors caught your eye? Are you wondering if you can install them in your apartment? Read our article to find out what this feature is used for and where it’s best to use it!
Doors with portholes are usually associated with a nautical style—more specifically, a sailor’s home. However, this feature is increasingly being used in interior doors in homes. It’s worth learning about its various applications.

Porthole – what is it? What are its characteristics?
Are you wondering what a porthole is and what it’s used for? A porthole is a small window located in a door. Traditionally, it’s installed in the walls of vessels, such as ships and yachts.
For this reason, it’s usually associated with ship design and nautical-style interior decor. Alongside an anchor or a lighthouse, it is a key element that emphasizes the connection between a given interior and the sea. However, this round porthole has found applications beyond nautical themes. It is increasingly used for lighting and decorating rooms.

A porthole can be used as a form of glazing. Installing interior doors with a porthole provides natural light while maintaining a sense of privacy. Such steel doors with a porthole do not create the sense of discomfort that fully glazed door panels might cause. This solution is very commonly used in bathroom doors. A porthole not only lets light into the room but also allows you to check if anyone is inside at any given time. In this case, however, it is recommended to install opaque glass in the porthole. It can be, for example, stained glass or frosted glass.

A porthole can be incorporated into exterior and interior doors—not just in homes. It is also used in door panels in public spaces, such as saunas and gyms. Such doors are not only practical but also aesthetically pleasing.
