Why Replace Just the Door? Uncovering the Core Problem
The medicine cabinet door is often the first part of the unit to show wear and tear. Constant use, moisture from showers, and accidental impacts can lead to a host of problems that detract from your bathroom’s appeal.
Common Signs of a Failing Medicine Cabinet Door
One of the most frequent issues is hinge failure. Over time, hinges can rust, loosen, or break, causing the door to sag, stick, or not close properly. This not only looks bad but can also be a safety hazard if the door becomes unstable.
Cosmetic damage is another major factor. A cracked mirror, peeling finish, or outdated design can make the entire bathroom feel dated. A fresh, new door is a quick and effective way to modernize the space.
The Hidden Dangers of a Damaged Door
A poorly fitting door can lead to moisture getting inside the cabinet, potentially damaging medications and toiletries. If the entire cabinet is falling off the wall, you have a much bigger problem, but the door is often the first warning sign of instability.
Beyond the obvious cosmetic issues, a damaged door can be a sign of underlying problems. For instance, if the door is misaligned, it might be putting stress on the cabinet’s mounting, a precursor to a more serious failure.
The 5-Step Solution to a Perfect Door Replacement
Replacing your medicine cabinet door is a straightforward project that most homeowners can tackle in an afternoon. Follow these detailed steps for a flawless installation.
Step 1: Identify Your Cabinet and Measure for the New Door
Before you can order a new door, you need to identify the manufacturer and model of your medicine cabinet. Look for a brand name or model number on the inside of the cabinet body. This information is crucial for finding an exact replacement.
If you can’t find any identifying marks, you’ll need to take precise measurements. Measure the height, width, and thickness of the existing door. Also, measure the distance between the hinge mounting holes, both on the door and the cabinet frame. Accurate measurements are the key to a successful replacement.
Step 2: Sourcing Your Replacement Door
With your measurements in hand, you can begin your search. Start by contacting the original manufacturer. Many companies sell replacement parts directly to consumers.
If the manufacturer no longer makes your model, don’t despair. There are numerous online retailers and custom cabinet makers who can create a door to your exact specifications. This is also a great opportunity to upgrade the style or material.

Step 3: Removing the Old, Damaged Door
Begin by carefully emptying the contents of your medicine cabinet. Have a helper support the door while you unscrew the hinges from the cabinet frame. It’s often easier to detach the door from the cabinet first, then remove the hinges from the door itself.
Be gentle during this process to avoid damaging the cabinet frame. Once the door is free, take a moment to clean the inside of the cabinet and the frame. This is also a good time to inspect the medicine cabinet rough opening for any signs of moisture or damage.
Step 4: Installing the New Hinges and Door
Attach the new hinges to your replacement door first. It’s highly recommended to upgrade to new hinges even if the old ones seem okay. Consider installing a soft close hinge insert for a touch of modern luxury and to prevent slamming.
With the hinges secured to the door, have your helper hold the door in position against the cabinet frame. Align the hinges with the pre-drilled holes on the frame and secure them with screws. Start with the top hinge, but don’t tighten it completely until all screws are in place.
Step 5: Final Adjustments for a Flawless Fit
Once the door is mounted, you’ll likely need to make some minor adjustments. Most modern cabinet hinges have adjustment screws that allow you to move the door up, down, left, or right. This allows you to achieve perfect alignment with the cabinet frame.
Take your time with this step, making small adjustments and checking the alignment after each one. The goal is to have a consistent, even gap around the entire door. A perfectly aligned door not only looks better but also functions more smoothly.
Choosing the Right Replacement Door: A Style Guide
Replacing the door is an opportunity to upgrade the style of your bathroom. Consider the overall design of the room when making your choice.
Matching Your Existing Decor
For a seamless look, choose a door that complements your existing fixtures and finishes. If your bathroom has a modern aesthetic, a frameless mirrored door is a great choice. For a more traditional space, a framed door with decorative molding might be more appropriate.
| Door Style | Description | Best For |
|---|---|---|
| Frameless Mirror | A single piece of mirrored glass. Creates a clean, minimalist look. | Modern and contemporary bathrooms. |
| Framed Mirror | A mirror surrounded by a wood or metal frame. Adds a decorative touch. | Traditional, transitional, and farmhouse bathrooms. |
| Wood Panel | A solid wood door, often matching the bathroom vanity. | Creating a warm, cohesive look. |
| Custom Etched/Frosted | Glass door with a decorative design. Adds a unique, personal touch. | Statement bathrooms and powder rooms. |
Beyond the Mirror: Exploring Material Options
While most medicine cabinet doors are mirrored, there are other options to consider. A wood door that matches your vanity can create a beautiful, custom look. You can also opt for a door with a decorative glass insert.
When selecting a material, consider the high-moisture environment of the bathroom. Choose materials that are resistant to warping and mildew. Factory-finished wood and high-quality metals are excellent choices.
Troubleshooting Common Installation Problems
Even with careful planning, you might run into some issues during installation. Here’s how to handle the most common problems.
Dealing with Misaligned Screw Holes
If the screw holes on your new door or hinges don’t line up with the holes on the cabinet frame, don’t force them. The best solution is to fill the old holes with wood putty, let it dry, and then drill new pilot holes in the correct position.
Drilling new pilot holes ensures that the screws go in straight and hold securely. Always use a drill bit that is slightly smaller than the diameter of the screw. This will prevent the wood from splitting.
Achieving the Perfect Door Alignment
Getting the door perfectly level and aligned can be tricky. Use a level to check for straightness. If the door is sagging, you may need to add a shim behind one of the hinges to raise it slightly.
Patience is key during the adjustment phase. Small, incremental turns of the adjustment screws will yield the best results. Don’t be afraid to walk away and come back with a fresh perspective if you’re feeling frustrated.
Frequently Asked Questions
Can I replace just the door of my medicine cabinet?

How do I measure for a new medicine cabinet door?
For a recessed cabinet, measure the height and width of the cabinet opening and add an overlay of about 0.5 to 1 inch on all sides. For a surface-mounted cabinet, you can simply measure the old door. It’s also important to measure for door swing clearance to ensure the new door can open without obstruction.
What tools are needed to replace a medicine cabinet door?
Common tools required for this project include a screwdriver, measuring tape, pencil, and possibly a drill and level.

Having the right tools on hand will help make the installation process smoother and safer.
How do I remove the old medicine cabinet door?
To remove the old door, you typically need to unscrew the hinges from the cabinet frame while supporting the door’s weight. If the door has a piano hinge, you may be able to drive the hinge pin out to separate the door. For sliding glass doors, you may need to remove a holding strip or fascia to lift the doors out of their tracks.
Is it difficult to install the new door myself?
Replacing a medicine cabinet door is often a manageable DIY project. The process generally involves attaching the new hinges to the new door and then mounting the door to the cabinet frame. Following the specific instructions for your new door and hinges is crucial for a successful installation.
