The most common mistake isn’t the install. It’s pulling the old cabinet off the wall before you’ve confirmed the new one uses the same mount type. Swap a recessed unit for a surface-mount box and you’re left patching a hole in the drywall.
Know what you’re buying first: our best medicine cabinet roundup covers the field, the recessed medicine cabinet with mirror guide explains in-wall fits, and the small medicine cabinet picks suit narrow walls. The in wall medicine cabinet guide digs into stud cavities, the medicine cabinet without mirror options skip the reflective front, and how to organize a medicine cabinet keeps the shelves usable once it’s mounted.
How Do You Remove the Old Cabinet Safely?
Start by cutting power at the breaker if the cabinet is lighted, then empty the shelves and lift the mirror door off its hinges if it’s removable. That drops the weight before you touch a single screw. Most surface-mount cabinets hang on two or four screws driven through the back panel into studs or drywall anchors. Two screws, usually.
Back those out with a drill, hold the box so it doesn’t drop into the sink, and set it aside. Recessed cabinets are trickier: they’re often screwed through the side flanges into the framing inside the wall, so you’ll feel around the interior edges for fasteners before pulling. Wirecutter recommends confirming the mount type before any demo, because that decision drives everything after it. If the old unit was caulked to the wall, score the seam with a utility knife first so you don’t tear the paint.
Surface-Mount or Recessed: Which Replacement Fits Your Wall?
Match the new cabinet to the opening you already have, or plan on drywall work. A surface-mount cabinet bolts flat to the wall face and needs no cavity, which makes it the safer swap when you don’t know what’s behind the drywall. A recessed cabinet sits inside the wall between two studs and reads cleaner because it barely projects past the surface.
The catch with recessed units is the cavity. Standard framing puts studs 16 inches on center, which leaves a rough opening of roughly 14.5 inches between them, so most recessed cabinets are built narrow enough to slide into that gap. Apartment Therapy notes that recessed cabinets suit small baths precisely because they don’t crowd the room. If your replacement is wider than the cavity, you’re cutting a stud and adding a header, which turns a 30-minute job into a half-day one.
How Do You Find and Frame Into the Studs?
Locate the studs before you drill anything, because a screw in bare drywall won’t hold a loaded cabinet. Run a finder across the wall and mark both edges of each stud, then snap a light pencil line for your top mounting height. A common finished height puts the cabinet mirror around 40 inches above the vanity, though eye level for the household matters more than any single number.
For a surface-mount cabinet, drive the mounting screws directly into at least one stud so the box carries weight instead of relying on hollow-wall anchors. For a recessed cabinet in an existing opening, the side flanges screw into the exposed stud faces. If you had to widen the opening, add horizontal blocking at the top and bottom so the flanges have solid wood to bite. That’s the whole trick: solid framing on all four sides.
Do You Need to Handle Electrical for a Lighted Cabinet?
Only if you’re replacing a lighted or LED cabinet, or adding one where none existed. Swapping a plain mirror cabinet for another plain one means no wiring at all. No wiring, no shutoff.
If the old cabinet had integrated lighting, shut off the circuit at the breaker and confirm it’s dead with a voltage checker before you disconnect anything. A lighted replacement should tie into an existing junction box inside the wall, with wire nuts matching hot to hot, neutral to neutral, and ground to ground. If there’s no box behind the wall, stop, because running new circuit wiring and setting a box is licensed-electrician territory in most jurisdictions and a bathroom’s proximity to water raises the stakes. When the wiring is already there, reconnecting a like-for-like fixture is a reasonable DIY step.
What You’ll Need
A clean swap comes down to three things: a stud finder to map the cavity, a level, and the replacement cabinet itself. Every pick below clears a 4.5 owner rating, and the finders cover two approaches, so match the tool to how you work.
EGHOME 16x28 Brushed Nickel Arched Medicine Cabinet - Metal Frame, Magnetic Door, Adjustable Glass Shelves
Pros
- Durable metal frame and cabinet body resist warping in humid bathrooms
- Tempered glass shelves are stronger and safer than standard glass
- Magnetic door closure eliminates visible hardware for clean lines
- Arched design elevates the look beyond basic rectangular cabinets
- Minimal assembly required out of the box
Cons
- No customer reviews yet to verify real-world durability
- At $180, costs more than basic builder-grade options
- Recessed installation requires wall opening and may need professional help
This cabinet solves the biggest complaint about builder-grade medicine cabinets: they look cheap and feel flimsy. The all-metal construction means no plastic edges to crack or warp when steam from your shower fills the room. That arched door is the detail that makes it feel custom rather than contractor-grade.
The magnetic closure is smarter than it sounds. You push it shut and it snaps flush against the frame with no visible latch or handle interrupting the mirror. It is the kind of small refinement that makes your bathroom feel more finished. The adjustable glass shelves mean you are not stuck with fixed spacing that wastes vertical room or forces you to store tall bottles sideways.
If you want a recessed medicine cabinet that looks intentional and built to last without paying custom prices, this one delivers.
Styles it works with: Modern Farmhouse, Transitional, Contemporary, Minimalist
Best placed in: Primary bathroom above vanity, guest bath for a polished look, powder room where the arched detail becomes a focal point
May not suit: Bathrooms with ornate traditional decor where the clean lines feel too modern, renters who cannot cut into walls for recessed install, very small bathrooms under 40 square feet where a 16-inch width feels oversized
Buy it if:
- You are renovating a bathroom and want storage that looks built-in
- You need a metal cabinet that will not warp in a steamy bathroom
- You want the arched detail without paying for a custom cabinet
Consider waiting if:
- You want to see verified customer reviews before committing at this price point
- You are hoping for a sale since the product is newly listed
Skip it if:
- You cannot install a recessed cabinet and need a surface-mount option
- Your wall opening is smaller than 16 inches wide
- You need a cabinet with interior lighting

The rare-earth magnet is strong enough to grab through drywall, and the felt backing means you are not leaving scuff marks as you search.
What makes it practical for home decor lovers is the built-in bubble level and marking notches. You find your stud, check that your frame or shelf will hang level, and mark your spot all with one tool. It is especially handy when you are rearranging a gallery wall or installing floating shelves, and you can stick several of these on the wall to map out your studs before you start drilling.
If you want a simple way to find studs for picture hanging without spending $40 on an electronic detector you will use twice a year, this one delivers.

This is the kind of tool that lives in your junk drawer and saves you every time you need to hang something heavy.

The rare-earth magnet is strong enough to stay put while you mark your spot, and the felt backing means you won't leave scuff marks on freshly painted walls.
What makes the two-pack especially clever is that you can stick one finder on each stud location, then step back to see if your shelf will hang level before you drill a single hole. The built-in bubble vial helps with that final check.

It sounds technical, but in practice it means you can actually see and reach everything on every shelf without contorting yourself or removing half your products to get to the back. The anodized aluminum construction is not flashy, but it matters in a bathroom where cheaper cabinets start rusting within a year.

The EGHOME arched recessed cabinet (4.7) mounts into the wall for a flush look, while the Kohler frameless mirror cabinet (4.5) works with either mount style. For locating framing, the Klein MSF100 magnetic finder (4.6) snaps to hidden screws and nails and doubles as a bubble level, the MSF1002 (4.6) is that same magnetic tool sold as a 2-pack, and the Klein ESF050 (4.6) is an electronic edge-to-edge finder with LED indicators that maps the full stud width instead of a single magnetic point.
Frequently Asked Questions
Can you replace a recessed cabinet with a surface-mount one?
Yes, and it’s often the easier direction. A surface-mount box covers the old wall opening as long as its footprint is larger than the hole, so you avoid drywall patching. Anchor it to a stud.
Do you have to turn off the electricity to replace a medicine cabinet?
It depends. A plain mirror cabinet has no wiring, so there’s nothing to shut off. If the unit is lighted, cut the circuit at the breaker and confirm it’s dead before touching any wires.
How big is the opening for a recessed medicine cabinet?
Most fit a rough opening of about 14.5 inches wide, the gap left between studs framed 16 inches on center. That’s why recessed cabinets are built narrow. Anything wider means cutting framing and adding blocking.
Can you install a medicine cabinet by yourself?
Yes for surface-mount and simple recessed swaps. The main challenge is holding the box level while driving the first screw, so clamp a temporary ledger board or ask for a second set of hands.
Does a medicine cabinet have to be screwed into a stud?
It depends on weight. A loaded cabinet holding glass, bottles, and a mirror door needs at least one stud anchor. Hollow-wall toggles alone can pull loose over time under repeated door swings.
Should the new cabinet match the old opening size exactly?
No, but bigger is simpler. A surface-mount cabinet larger than the old hole hides it entirely. A recessed replacement should match the existing cavity, or you’ll be reframing the opening.
Is it worth hiring a pro to replace a medicine cabinet?
It depends on the wiring. A like-for-like mirror swap is a solid weekend DIY. Bring in a licensed electrician when there’s no junction box, or when you’re adding lighting where none existed before.
Bottom Line
For most people, a like-for-like swap solves it: match the new cabinet to the mount type and opening you already have, anchor it to a stud, and check level twice before the final screw. A surface-mount replacement is the forgiving choice when you can’t see behind the drywall. Stop and call a licensed electrician the moment you find lighting with no junction box behind it, because water and improvised wiring don’t mix.
