Sauna room doors can be purchased after you’ve already installed your sauna and want to upgrade the appearance of the entrance, or if you want something jazzier than what came with your kit.
The door you select for the sauna room must not only be able to stand up to exposure to high dry heat and humidity, but its parts - the window, handle, hinges and other hardware - will be under the same stress.
Since the door is one of the most important parts of a sauna room and one that has both a functional as well as aesthetic look, you’ll want to get the door installed correctly or the result will be a loss of heat.
You can order a door either by itself or already pre-hung on a frame. If you get the door pre-hung, it will come complete with jamb, threshold, hinges, ball catch and wooden handle, and will only cost an extra $100. If you are building a custom sauna room from scratch, a pre-hung door could save you a lot of time and trouble.

Other notes for installing the sauna door:
Should the hot air and humidity in the sauna room eventually cause the door to swell, you may need to follow the steps above to adjust the door, or replace it altogether.
If you do need a new door for your sauna room installation, there’s a variety of doors for sale on the internet to choose from. Some inexpensive styles come in solid wood, while others are more elaborate; they come with artistically etched glass, or they can be ordered with clear or obscured glass.
The choice of door will depend on your preferences for privacy or if you want to let in outside light to a wood-burning sauna room that does not have electricity or lights. The windows on these doors must be made of tempered safety glass in order to withstand the extremes and changes of a sauna room.
You should pass on any sauna room doors that contains lexan acrylic instead of glass as the lexan scratches easily and will discolor within a few years.
