You could paint the othger three how you wish and I would just paint the door under the stairs the wall color. You really are not looking to make that door a feature or really noticed entity, you just kind of want it there and to blend in and sort of disappear.

Am not sure painting your doors the same color as the walls is a good idea. Would suggest a crisp white for doors and trim including the door to the understair area.

Fair point. I meant a more neutral color (a crisp white) as opposed to a black

Bold doors should lead to something equally bold or great......

Do closets or STAIR qualify? Not usually: )

Alternatively you CAN install a standard height door there, the top part of the door would be 'blind' when opened. Could lead to some knocked heads but can look better. I had this situation in a previous house where the bedroom had full height ceilings but the hall outside had a slope (roof) that would have clipped the top corner of the door off. By leaving the door square it looked much better from the bedroom side and avoided a custom door.

@Jan Moyer, I’m not sure I agree with this statement. Does a bedroom, laundry room or bathroom qualify? I’m more focused on uniformity and symetrt

@hallet & Co, wish this was an option. The door under the stairway is 6’8” so not worried about folks hitting their heads generally. Our other doors are 8’ and there is just not enough space under the stairway for a door that height

But there is enough space in the wall- I assume the wall is standard height on the hall side but you are accessing the space under the stairs with a lower ceiling?

Yes because he landing is not at 10ft (the overall ceiling height)and the door is under where the stairs increase in height to the second floor.

Does this picture help? See the door with a triangle of the opening blocked? That’s the roof slope and I didn’t want a funny shaped door in the bedroom so the wall was framed for a standard door even though the roof rafter blocked the top left corner. Now imagine in your house an 8’ door in a 10’ wall. When you open the door the top 16” would be a blank panel because the room beyond only has an 80” ceiling height.
