Doors
Two questions settle this page: how wide is your rough opening, and do you want to see into the room or not.
Every door here arrives prehung in its own frame, so your job is a plumb, square opening rather than fitting a slab to a jamb on site. That is roughly the difference between a morning and a weekend.
For glass, the ProSaunas all-glass door is the one most people picture, and its reversible hinges let you set the swing direction at install instead of having to choose at checkout. Thermory’s Modern Black pairs gray glass with black hardware in a reversible frame, and its Premium door frames the glass in thermo-aspen.
For wood, the PROSAUNAS prehung door is solid Douglas Fir with a natural Hemlock jamb, handcrafted in Minnesota, with insulated dual-pane tempered glass and self-closing hinges. It comes in four widths: 24, 26, 30, and an ADA-width 36 inches.
The mistake we watch for is ordering the door on its own. A door is not a moisture barrier. The wall it sits in still needs foil with taped seams, and the room still needs its two vents, so put those on the same order while the wall is open. All of it is in sauna materials.
Call or text (844) 565-1113 with your rough opening width and we will tell you which of these fits.
