However, installing a door under the stairs is relatively easy. We will explain this installation in two parts. Follow these steps to install your stair closet door:

Cut Opening 

• Place your pre-hung door where you want the door to be, and make sure there is space by each door border and jamb. The areas should be equal enough for the door to swing without resistance or obstructions. Adjust the door till you get a perfect position. 
• Use a pencil or chalk to trace the door jamb outline on the stair wall. Then remove the door from the wall. 
• Put a protective material or cloth on the floor to protect your floors from damage. Then use a sawblade to cut through the stair’s drywall or wood. Cut slowly and expose the wall frame. You must ensure no electrical wiring or fitting is around the hole you are cutting. 
• You can use a wood-cutting blade if the saw needs to do a better and faster job. Cut through the studs and ensure that your cut is according to the outlined measurement you took. 
• Once the opening is ready, cut two pieces of a two by four plywood to use as a trimmer. Attach the trimmers to both vertical sides of the wall. Ensure that the trimmers align perfectly with each other. Trimmers help hold the wall load and prevent it from caving in. it also serves as the door frame. 
•  Use your screw drill to drill several screws into the trimmer, attaching it to the stairs wall. The screws should be 8 inches apart from one another. Once this is done, you will have a door frame and are ready for the proper installation. 

Door Installation 

• Insert the door into the door frame opening to ensure it fits perfectly. There should be a little space for the hinges to work correctly. 
• Bring out the door and cut a mortise on the door for your hinges using a chisel. You can ignore the mortise cutting if you want to use a non-mortise hinge. Measure and mark your hinge positions along the door length. 
• Using a screw drill, screw the hinges into the door at their appropriate positions. Then drill screw holes in the door frame where the hinge screws will enter. 
• Lift the door and hang it onto the door frame. With the door in position, screw your hinges tight. Ensure that the screws are very tight. Otherwise, they might come off briefly or make squeaky sounds. 
• Finally, install your door handle or knob. It is best to use a short doorknob. Remember, you are trying to conserve space.  

It’s essential to measure the opening where you plan to install the door carefully so you purchase the correct size door. Use a level to ensure that the door is installed straight and even. A circular saw or handsaw will be needed to cut the door opening to the correct size, and a drill will be necessary to install the hinges.

You will also need wood chisels to create recesses in the door and frame for the hinges and screws to attach the hinges to the door and frame. Use wood glue to secure the door’s hinges and fill any gaps between the door and the frame. Sandpaper can be used to smooth the edges of the door and frame.

Once the door is installed, you can paint or finish it to match your decor. Remember to wear safety glasses and gloves when using power tools and handling sharp objects.
