Step-by-Step Guide to Create the Rough Opening

Clearing the Space

Start by clearing the area around where you plan to install the door. Remove any drywall, plaster, or other materials to expose the studs on both sides of the wall.

Measuring and Marking

Measure the width and height of your door, and mark these dimensions on the wall where the rough opening will be.

Cutting the Opening

Using a circular saw, carefully cut along the marked lines to create the rough opening.

Framing the Opening

Frame the rough opening with 2×4 lumber, ensuring it’s plumb and level. This frame will provide support for the door.

Checking for Plumb and Level

Use a level to make sure the frame is plumb and level. Adjust as necessary by adding shims behind the frame.

Installing the Door Frame

Install the door frame kit into the rough opening, securing it to the studs with nails. Follow the manufacturer’s instructions for proper installation.

Insulation and Weatherproofing

Add insulation around the door frame to improve energy efficiency. Apply weatherstripping to seal any gaps between the door frame and the wall.

With the rough opening ready, you can now prepare to install the bathroom door itself. Follow the door manufacturer’s instructions for installation.
