How to Make a Large Bathroom Mirror Redo to Double Framed Mirrors and Cabinet DIY

If your bathroom still has that huge builder-grade mirror stretching wall-to-wall over the vanity, you are not alone. They’re practical, surebut they also scream “contractor special” and rarely match your style. The good news? You can transform that giant sheet of glass into two stylish framed mirrors with a custom cabinet in between, all with a weekend DIY project and a reasonable budget.

Inspired by popular Hometalk-style makeovers, plus advice from DIY blogs that specialize in framing builder-grade mirrors and adding storage, you can pull off this upgrade without hiring a pro. The result looks like a custom remodel: double mirrors, extra storage, and a bathroom that suddenly feels intentional instead of “builder basic.”

Why Redo a Large Bathroom Mirror Into Double Framed Mirrors?

Before we dive into tools and lumber, it’s worth understanding why this project is so popular in real-life remodels:

1. It Makes a Builder-Grade Bathroom Look Custom

That one massive mirror may be convenient, but it rarely looks high-end. Splitting the space into two framed mirrors over a double vanity adds symmetry and gives the room a boutique-hotel vibe. Many homeowners report that framing or replacing their big mirror is one of the fastest visual upgrades they’ve madeoften for under $100–$150, depending on materials.

2. You Gain Extra Storage With a Center Cabinet

By turning the center section into a wall cabinet, you add hidden storage for toothbrushes, skincare, medicine, and hair products that normally clutter your countertop. DIYers often build shallow cabinets 4–6 inches deep so doors can open easily above the faucet area while still holding everyday essentials.

3. You Don’t Have to Live Through a Full Gut Reno

Instead of ripping out tile, drywall, or the entire vanity, you’re basically giving the mirror a makeover. Most projects involve:

• Safely removing or modifying the existing mirror
• Framing new mirrors or reusing cut sections
• Building a simple cabinet box and door
• Painting or staining to tie everything together

Compared with a full remodel, this is low mess, low risk, and high rewardperfect for a first “big” DIY.

Step 1: Decide Remove the Big Mirror or Work With It?

The original Hometalk-style project usually takes one of two routes:

1. Remove the large mirror and replace it with two separate mirrors and a cabinet.
2. Keep the mirror on the wall, add trim to visually “split” it into two framed mirrors, and mount a shallow cabinet in front of the center section.

Removing a glued mirror can damage drywall if you rush, so weigh your comfort level. Big-box tutorials recommend taping the entire mirror with painter’s tape, using safety glasses and gloves, and loosening adhesive with gentle heat before prying. If you’re not comfortable with glass and drywall repair, the “leave it up and add trim” option is kinder to your nerves.

How to Inspect Your Existing Mirror

• Check whether it’s held with clips, mastic (glue), or both.
• Look for chips or black spots around the edgesthese can often be hidden with a frame.
• Measure the overall width and height, plus the space between the sinks to plan your cabinet size.

If the mirror is in good shape and firmly attached, framing in place is usually the easiest route.

Step 2: Plan Your Layout and Measurements

Grab a tape measure, notepad, and maybe a snackthis part matters.

Key Measurements You Need

• Total mirror width and height
• Centerline of each sink (measure from one side wall or vanity edge)
• Desired cabinet width (often 18–24 inches for a double vanity)
• Clearance from faucets to the bottom of the cabinet doors

Many designers suggest centering each mirror over its sink for a balanced look, then fitting the cabinet in the remaining middle space. Sketch a quick front view of your wall and mark:

• Left framed mirror
• Center cabinet outline
• Right framed mirror

This sketch will help you calculate the outer dimensions of each mirror frame and cabinet, and how wide your trim boards should be.

Step 3: Gather Tools and Materials

Your exact list will vary by design, but most DIYers use a combination of:

Basic Tools

• Miter saw or miter box and hand saw
• Drill/driver and bits
• Stud finder
• Level and tape measure
• Caulk gun
• Sanding block or orbital sander
• Safety glasses and cut-resistant gloves

Materials for Double Framed Mirrors

• Two mirrors (or cut sections of the existing mirror)
• MDF or wood trim boards for frames (1×3, 1×4, or decorative casing)
• Mirror mastic or compatible construction adhesive made for glass-to-wood or glass-to-wall bonding
• Painter’s tape and drop cloths
• Wood filler, caulk, and paint or stain

Materials for the Center Cabinet

• 1×12 or 3/4-inch plywood for cabinet box
• 1×2 or 1×3 boards for face frame
• Cabinet door (store-bought or DIY)
• Small hinges and knob/pull
• Shelf pins and shelves (optional)
• Anchors or screws for mounting into studs

For a faster project, some bloggers use pre-made framed mirrors from big-box stores, then build only the cabinet to fit between them.

Step 4: Safely Remove or Prep the Existing Mirror

If You’re Removing the Mirror

1. Protect everything. Lay down drop cloths, cover the vanity top, and tape cardboard along the countertop edge.
2. Tape the glass. Use wide painter’s tape in a grid or large X pattern across the entire mirror. This helps contain shards if it cracks.
3. Remove clips. If there are plastic or metal clips at the top, loosen them while someone else supports the mirror.
4. Loosen adhesive. Gently heat the mirror with a hair dryer or heat gun on low, then work plastic shims or putty knives behind the mirror to separate it from the wall, moving slowly.
5. Lower the mirror carefully. Once the top is loose, tilt and lift the mirror off the wall with a helper.
6. Repair the drywall. Scrape off remaining mastic and patch torn paper or divots with joint compound.

If You’re Keeping the Mirror

If you leave the big mirror in place, clean it thoroughly and lightly sand or degloss any wall paint around it where trim will attach. Some DIYers build “stick-on” frames that adhere directly to the mirror using strong construction adhesive or double-sided mounting tape, avoiding any wall damage.

Step 5: Build and Install the Center Cabinet

The cabinet is the star of this projectit breaks up the long mirror and adds storage.

1. Build the Cabinet Box

1. Cut two sides, a top, and a bottom from 3/4-inch plywood or 1×12 boards.
2. Assemble a simple rectangular box using wood glue and screws or pocket-hole joinery.
3. Add a back panel (hardboard or plywood) if you want a fully enclosed cabinet; otherwise, mount directly to studs and let the wall act as the back.
4. Attach a face frame made from 1x2s or 1x3s to give the cabinet a finished edge and match the mirror frames.

2. Mount the Cabinet

1. Use a stud finder to mark studs where the cabinet will hang.
2. Hold the cabinet in position (you may want a helper or temporary ledger board).
3. Drive cabinet screws through the back (or through a French cleat) into studs.
4. Check with a level before fully tightening.

Make sure the bottom of the cabinet clears the faucet height and doesn’t block your view too much while still aligning nicely with the top of the mirrors.

3. Add the Door and Shelving

• Install hinges and hang the door so it swings away from the most-used sink.
• Add a knob or pull that coordinates with your faucet and hardware.
• Insert adjustable shelves for flexible storage of bottles, jars, and small baskets.

Step 6: Frame the Double Mirrors

Whether you’re framing separate mirrors or visually dividing a single mirror, the basic steps are similar.

1. Cut the Frame Pieces

1. Measure the outer dimensions of each mirror section.
2. Cut top and bottom frame boards to length with 45° mitered ends.
3. Cut side pieces to height, also with mitered ends.
4. Dry-fit all pieces around the mirror to confirm sizing.

Many DIYers use baseboard or decorative casing for a more custom look, then add a small secondary trim (like shoe molding) inside for extra detail.

2. Deal With Mirror Clips and Gaps

If your mirror uses clips, you can:

• Notch the backs of the frame boards where they hit the clips, or
• Replace the bulky clips with low-profile brackets so the frame sits flat.

Use a chisel, router, or oscillating tool to create shallow pockets for the clips, then test-fit again to ensure the frame rests flush against the mirror.

3. Assemble and Attach the Frames

1. Either pre-assemble the frame on a flat surface or build it in place on the mirror (the “stick-on” approach).
2. Apply mirror-safe adhesive or strong construction adhesive to the back of the frame, avoiding the inner edge where it might squeeze onto the glass front.
3. Press the frame onto the mirror or wall, use painter’s tape as “clamps,” and check for level.
4. Let the adhesive cure per manufacturer instructions before removing tape.

Once both mirror frames and the cabinet are installed, you’ll start to see that magazine-worthy transformation.

Step 7: Caulk, Paint, and Finish Like a Pro

The finishing touches are what make your DIY look intentional instead of “weekend project gone rogue.”

Fill, Sand, and Caulk

• Fill nail holes and seams in the wood with wood filler; let dry and sand smooth.
• Run a thin bead of paintable caulk where the frames meet the wall and where the cabinet face frame meets the wall for a seamless look.
• Wipe excess caulk with a damp finger or caulk tool.

Prime and Paint (or Stain)

Use a good-quality primer on bare wood or MDF, then finish with semi-gloss or satin paint for wipeable, bathroom-friendly surfaces. Many homeowners choose:

• White for a classic spa vibe
• Black or deep charcoal for modern contrast
• Warm wood stain for a rustic or farmhouse look

Try to match or intentionally contrast your vanity color and hardware. This creates a cohesive design that feels thoughtfully planned.

Step 8: Style Your New Double Mirrors and Cabinet

With construction done, it’s time for the fun partstyling.

• Add matching sconces on either side of the cabinet for better lighting.
• Use the cabinet to hide away everyday clutter: toothbrushes, razors, cotton pads, and skincare.
• Place a small plant or candle between the sinks to soften the straight lines.
• Hang matching hand towels beneath each mirror to visually anchor the space.

The final look can rival many inspiration photos you see on Hometalk, Pinterest, or design blogsbut you’ll know you built it yourself.

500-Word Experience: What It’s Really Like to Redo a Large Bathroom Mirror

On paper, “How to Make a Large Bathroom Mirror Redo to Double Framed Mirrors and Cabinet DIY” sounds straightforward: a few boards, some screws, a little paint. In real life, it’s a mix of “This is amazing!” and “Why is there sawdust on my toothbrush?”and that’s okay.

The first big moment is usually standing in front of that massive mirror with painter’s tape and a heat gun, wondering if this is the day you accidentally create seven years of bad luck. That’s why so many DIYers swear by over-prepping: extra tape, heavy drop cloths, a helper nearby, and a slow, patient approach to loosening the glass. Once you see even a tiny gap between mirror and wall, your confidence jumps about 200%. The mirror removal turns from terrifying to oddly satisfying.

Another common experience: realizing how much measuring matters. It’s easy to look at inspiration photos and think, “Two framed mirrors and a cabinetgot it.” Then you discover that if your frames are off by even half an inch, the mirrors won’t line up with the sinks, and your brain will notice every time you brush your teeth. Many DIY folks say they measured, re-measured, and even made cardboard templates for the cabinet before cutting actual wood. That extra half hour with a tape measure can save you a lot of patching later.

Building the cabinet tends to be the “aha” moment. Suddenly you realize how much storage you’ve been missing. People often say that the cabinet ends up holding all the little things that drove them crazy on the countertopfloss, travel-size lotions, kids’ toothpaste, and the 14-step skincare routine that can finally live behind a door instead of scattered around the sink. It’s a small change that makes everyday life less chaotic.

There’s also a real sense of pride that comes from the finishing details. Caulking, sanding, and painting are not glamorous, but they’re what make your project look like a high-end custom installation rather than “my first DIY experiment.” Many homeowners share that once they saw the freshly painted frames and the cabinet all in one color, the bathroom suddenly felt “finished” in a way it never had beforeeven if the flooring or vanity were still original.

Emotionally, this project often becomes a gateway DIY. If you can safely work with glass, build a cabinet, and install trim that looks good enough to see before coffee every morning, you start to believe you can tackle bigger projectslike tiling a backsplash or upgrading the vanity next. It’s not just about the mirrors; it’s about building skill and confidence.

And then there’s the moment someone walks into your bathroom and says, “Whoa, when did you remodel?” You get to smile, shrug casually, and say, “Oh, I just redid the mirror and added a cabinet. No big deal.” (Secretly, you know it was a big deal, and you earned every compliment.) That’s the Hometalk spirit: taking an ordinary builder-grade feature and turning it into something that feels like you.
