A medicine cabinet does two jobs in one: it holds medicines, skincare and grooming tools off the counter, and it replaces the wall mirror you would otherwise hang separately. In a bathroom under about 40 square feet that matters, because there is no spare wall to give up twice.
We compared 12 wall, corner and over-toilet cabinets and sorted them by the thing that decides a purchase in a small room: exterior width and depth. Every pick below lists exact inches, because a wall-mounted cabinet is the least forgiving thing you can buy for a tight bathroom.
Are medicine cabinets in bathrooms outdated? No. What changed is the shape of them: slim 5 to 7 inch bodies, corner units, behind-the-door designs and LED-lit mirrors have moved up, while deep builder-grade boxes have not.

1. Spirich Corner Bathroom Cabinet: Best Overall When the Walls Are Gone
Spirich Corner Bathroom Cabinet with Doors and Adjustable Shelf, White
23.62 inch W x 12.4 inch D x 31.89 inch H
Engineered wood
Floor mount corner unit
25.8 lb, 35 lb capacity
Pros
- Right-angle design uses dead corner floor space
- Substantial engineered wood build
- Simple assembly with labeled hardware
- Beadboard doors suit many decor styles
Cons
- Interior volume smaller than buyers expect
- Instructions confuse a few users
- No mirror front
When every wall is occupied, the corner is the last usable surface in the room. This 23.62 inch wide by 12.4 inch deep right-angle unit adds enclosed storage without claiming any wall at all.
It holds 4.6 stars across 1781 ratings, the strongest rating and review-volume pairing we found, which is why it leads this list. The FSC-certified engineered wood feels solid for a flat-packed cabinet at 25.8 pounds, and the raised-panel doors read as furniture rather than a plastic box.
The caveat is the interior: two doors and one adjustable shelf, which buyers consistently call smaller or shallower than they pictured. Plan it for daily medicines and small bottles, not a family restock. It is also a floor-mounting piece that needs a genuine corner with two clear walls.
Who this corner cabinet suits
It suits half baths, powder rooms and apartment bathrooms where the corner is empty and the floor is the only free surface left. Two people can carry it in and assemble it with basic tools, usually in under an hour.
Who should skip it
Skip it if you need a mirror over the sink, since this is a plain door unit, and skip it above the toilet. Renters should confirm the corner clears the door swing before ordering.
2. SoBuy Over Toilet Wall Mount Medicine Cabinet: Best Over the Toilet Fit
SoBuy Over Toilet Wall Mount Medicine Cabinet, Wall Size, White
21.7 inch W x 7.9 inch D x 23.6 inch H
Wall-mounted over toilet
MDF with painted finish
Two doors with one adjustable shelf
Pros
- Compact footprint for small bathrooms
- Shelf adjusts to three heights
- Detailed instructions and mounting hardware included
- Smooth painted finish wipes clean
Cons
- Shallow depth limits upright storage
- Feels light beside larger models
- Best for light items
At 21.7 inches wide and 23.6 tall, this spans a standard toilet tank without crowding the flush handle, which is the failure point behind so many wasted over-the-toilet purchases.
It rates 4.5 stars across 970 ratings, and owners highlight the clean modern look, quick assembly and useful capacity in guest bathrooms and laundry rooms. The single shelf sets at three heights so tall bottles and short tubes share one compartment.
Depth is the limitation. At 7.9 inches it clears most tanks, but the interior is genuinely shallow, and buyers note it is smaller than they expected. Flat tubes and squat bottles fit; a full pump bottle does not. Owners also describe it as feeling less substantial than larger models, so use solid wall anchors.
Check before you buy
Measure the clear space behind the tank, not the tank width alone. You need roughly 7.9 inches of depth for the body plus a little room for the tank lid and the flush lever.
Where it falls short
If the gap behind your toilet is already tight, go narrower rather than forcing this one. And in a room with weak ventilation, the painted MDF surface is the part that shows wear first.
3. Tangkula Mirrored Wall Cabinet: Best Storage Density on a Usable Wall
Tangkula Bathroom Medicine Cabinet with Mirror, Modern Wall Mounted Space-Saving Storage Organizer with Mirrored Door, 4 Internal Shelves & 6 Open Side Shelves, Bathroom Wall Cabinet (White)
26 inch W x 6.5 inch D x 25 inch H
Wall mount
Engineered wood and glass
4 internal plus 6 side shelves
21 lb
Pros
- Highest shelf count in this roundup
- Mirrored door doubles as a grooming mirror
- Waterproof surface wipes clean
- Magnetic catch and metal knob
Cons
- Mirror shows fingerprints
- Wall mounting needs correct anchors
- 26 inch width is wide for a small wall
This is the pick for the bathroom that has one usable wall strip and needs a mirror plus storage on it. At 26 inches wide, 25 tall and only 6.5 deep, the Tangkula unit puts ten shelves behind and beside a single mirrored door.
It carries 4.4 stars across 1976 ratings, the largest review base in the set, and reviewers repeatedly point to how much storage fits in a slim body. Four internal shelves, three removable, plus six open side shelves for quick-access bottles.
The mirror is the honest tradeoff: a recurring minor complaint is fingerprinting, which matters where the mirror is touched constantly. At 21 pounds with a 66 pound capacity rating, this is the most substantial wall-mounted unit here, though owners note the anchors must suit your wall type rather than relying on a drywall plug.
Why the shelf count matters
Ten shelves in a 6.5 inch deep body is what separates this from a plain two-shelf cabinet. The open side shelves hold daily items visibly while medicines go behind the mirror, and that single decision clears a lot of counter clutter.
When it does not fit
Twenty-six inches is not small. If your only free wall gap is under about 20 inches, skip to the next pick. There is also no defogger pad, so in a steamy room you will wipe the mirror more often.
4. Tangkula Louvered Wall Cabinet: Best 16.5 Inch Wide Fit
Tangkula Medicine Cabinet, Wall Mounted Bathroom Cabinet Single Door Wooden Bathroom Wall Cabinet with Adjustable Shelf
16.5 inch W x 6.5 inch D x 27.5 inch H
Wall mount
Engineered wood with louvered door
One adjustable shelf
13 lb
Pros
- Narrow width fits tight wall gaps
- Three-position adjustable shelf
- Louvered door improves airflow
- Round handle and magnetic catch
Cons
- 6.5 inch depth constrains larger bottles
- Wood-look engineered wood finish
- Works better as secondary storage
Sixteen and a half inches wide is the number to remember here. It fits beside a vanity, in the gap between a tub edge and a wall, or above a compact vanity in a guest bath where a 20 inch box will not go.
It holds a 4.4 rating across 532 reviews. Buyers like the slim wall-mounted footprint and the ventilated louvered door, and report the adjustable shelf handling a good range of toiletries without the unit bowing.
The louvered door is a working feature, not decoration: slatted venting moves air through the interior, which matters in a small room where the cabinet warms up every time the shower runs. Depth is the constraint, and at 6.5 inches taller containers have to live elsewhere.
How it fits beside a vanity
Measure clear wall width rather than vanity width. A 16.5 inch cabinet clears most small vanity ends, and the tall vertical format needs far less wall height than a square unit of the same width.
When to choose something else
Choose something else if you store bulk or tall products, since one shelf at 6.5 inches deep will not carry a family restock. In a bathroom with no working fan, the painted finish shows wear first.
5. CHOEZON Mirrored Medicine Cabinet: Best Small Mirror and Storage Combo
CHOEZON Bathroom Medicine Mirror Cabinet, 13.8'' x 19.7'', Wall-Mounted Bathroom Vanity with Mirror, Bathroom Medicine Cabinet with Storage Function, Hanging Storage Cabinet, Adjustable Shelves, White
13.78 inch W x 5.51 inch D x 19.69 inch H
Wall-mounted
Particleboard with mirrored door
Two adjustable shelves
13.82 lb
Pros
- Clear distortion-free mirror in a compact body
- Two shelves at three height positions
- Reversible door handing
- Lightweight enough for a simple install
Cons
- Two-person job for wall mounting
- Particleboard can crack near hinge screws
- Brand advises against plaster walls
At 13.78 inches wide and 5.51 deep, this is the smallest mirror-and-storage combination in the roundup. If your wall gap is genuinely narrow, this is the unit most likely to fit on the first attempt.
Owners like the mirror clarity, the soft-close doors and how much storage the size delivers, giving it 4.4 stars across 478 reviews. The precision hinges adjust so the door closes evenly, and the door fits either hand opening.
Why the 5.5 inch depth matters
Depth is where small bathrooms win back usable room. A 5.51 inch projection lets a door in front of the cabinet still open, which a 7 to 8 inch body does not guarantee in a tight room. Two shelves at three height settings handle a daily routine well for one or two people.
What to watch before mounting
Mounting is a two-person job, and one review describes the particleboard body cracking at the hinge screw while unsupported. The manufacturer also advises against hollow or plaster walls, which rules it out in homes built before 1940 without a stud.
6. Homleke Barn Door Wall Cabinet: Best Value for Small Bathrooms
Homleke Bathroom Wall Cabinet, Medicine Cabinet with Adjustable Shelves
21.7 inch W x 7.9 inch D x 23.6 inch H
Wall mount
MDF with moisture-resistant finish
Three shelves, two doors
18 lb
Pros
- Three tiers of adjustable shelving
- Moisture-resistant MDF finish
- Complete accessory kit and clear instructions
- Metal handles add durability
Cons
- Barn door hardware draws attention
- White engineered wood shows scuffs
- Needs a modern farmhouse look
This is the strongest rating paired with meaningful review volume: 4.6 stars across 458 ratings, with buyers describing a tidy over-the-toilet solution for small bathrooms. Its 21.7 by 7.9 by 23.6 inch footprint matches the SoBuy above, so the two compete for the same wall gap.
What separates it is shelving. Three tiers of adjustable and removable shelves across three compartments hold a noticeably larger volume of toiletries than a single-shelf cabinet, while the shallow vertical layout keeps the footprint tight.
The barn-style doors give it a modern farmhouse look, and the moisture-resistant white MDF finish is specified for humid rooms. At 18 pounds with metal handles it is heavier and more stable than the lighter units here, and owners consistently call the wall installation straightforward.
Who should buy this one
Buy it if you want the most storage per square foot of wall and your decor can carry a farmhouse or transitional detail. Three compartments let you dedicate one tier to daily items and another to refills.
Where it will not work
It will not work in a minimal bathroom where sliding hardware and white MDF are the wrong visual language, and the white finish shows scuffs in a high-traffic guest bath. It needs a stud or solid anchor, not a drywall plug.
7. Fundin Black Beveled Mirror Cabinet: Best Recessed Ready Design
Plastic Black Medicine Cabinet 16x24 Beveled Mirror, Recessed/Surface Mount
16 inch W x 4.3 inch D x 24 inch H
Recessed or surface mount
Plastic carcase, black metal frame
Two shelves
9.7 lb
Pros
- Installs recessed or surface mounted
- Reversible door handing
- Arrives fully assembled
- Lightweight body wipes clean
Cons
- Plastic shelves feel flimsy
- Mounting holes may need enlarging
- Weak magnetic catch
- Frame can dull with steam
This is one of only two picks here that works as a recessed install, and it publishes exact cavity numbers, which is rarer than it should be. The recessed box measures 13.5 inches wide by 17.6 tall by 3.1 deep, and the required wall opening is 13.6 by 17.7 by 3.3 inches.
With those figures you can check your wall before you buy. A 3.3 inch opening fits a standard framed wall, and the same hardware lets it hang on the surface if your wall is thinner or already has an old opening.
It arrives fully assembled, which matters in a small bathroom where there is nowhere to stand and lay out flat-pack panels. Reviewers rate it 4.4 across 431 reviews, and several note that 16 inch widths are hard-to-find sizes that fit small bathrooms and RVs.
How to know if recessed is possible
Run a stud detector along the intended wall and measure between studs. A recessed box needs about 3.3 inches of depth and roughly 13.6 inches of width, so it fits standard 16 inch stud spacing without cutting a stud.
What to watch out for
Buyers describe the plastic shelves as flimsy against wood models, and several report enlarging the mounting holes. The magnetic catch is weak and the metal frame can dull in humid rooms. A 10 kilogram capacity suits medicines, not a loaded family store.
8. ChooChoo Small Medicine Cabinet: Best for Powder Rooms
ChooChoo Small Medicine Cabinet with Towel Bar, Hanging Storage, 3 Hooks
15 inch W x 7 inch D x 22 inch H
Wall mount
Engineered wood, open frame
One shelf, towel bar, three hooks
12 lb
Pros
- Very compact 15 inch width
- Removable towel bar plus three hooks
- Numbered hardware and clear instructions
- Magnetic closure works smoothly
Cons
- Interior smaller than buyers anticipate
- Included anchors are flimsy in drywall
- Doors can swing closed on their own
Fifteen inches wide by 22 tall makes this the smallest wall-mounted unit in the roundup, and it is the one to point a reader toward for a powder room with no vanity storage at all.
Owners like the size and the off-white farmhouse styling, and it holds 4.4 stars across 325 reviews. A closed cabinet, an open bottom compartment, an adjustable shelf, a removable towel bar and three hooks give a lot of function from a small footprint.
The complaints are consistent: the interior is smaller than some buyers expect, the doors can swing closed on their own, and the supplied anchors are not suitable for drywall alone. Buy anchors matched to your wall rather than trusting the fixings in the box.
Best use in a powder room
A powder room has no shower, so humidity is a smaller problem and a compact unit is a safe bet. Use the open compartment for spare rolls and the hooks for a towel, a robe and a spare cloth.
Where it falls short
At 12 pounds it is light enough for one person to hold and mount, which makes it realistic for a renter using adhesive mounting. But there is no mirror, so plan a separate one, and the 7 inch depth projects further than a 5.5 inch model.
9. HOOBRO Double Mirrored Wall Cabinet: Best Lightweight Option
HOOBRO Medicine Wall Cabinet with Mirror, Bathroom Storage Cabinet with Hidden Space and Towel Bar, Double Mirrored Doors, Detachable Shelf, for Bathroom, Living Room, White BW41CW01
16.1 inch W x 7.1 inch D x 24.8 inch H
Wall mount
Engineered wood, metal frame
Two shelves, two mirrored doors
6.9 kg
Pros
- Compact width works in small bathrooms
- Twin mirrored doors conceal stored items
- Open shelves plus hanging rod
- Metal X-frame sides reduce shaking
Cons
- Particleboard can split if a drill is used
- No knobs so mirrors show fingerprints
- Mirror corners arrived chipped on one unit
Two mirrored doors with a push lock is an unusual combination, and it is why this cabinet works in a shared family bathroom. Contents stay hidden rather than on display, which matters in a room a guest can see.
At 16.1 inches wide, 7.1 deep and 24.8 tall, it holds a 4.4 rating across 213 reviews. The black metal X-shaped side frame keeps the particleboard body from shaking when you open a door, which is normally when a light cabinet feels cheap.
Assembly is where care is needed. Owners report that particleboard can split if a power drill is used and recommend an electric screwdriver instead. With no knobs you push the doors open, so the mirror picks up fingerprints with no handle to grip instead.
Why the push-lock doors help
Mirrored doors add a surface to clean, but they also hide the contents. For a family cabinet holding prescriptions and first aid supplies, privacy usually wins, and 16 inch width fits almost any remaining wall strip.
When to skip it
Skip it if you are comfortable with a power drill and impatient, because the particleboard carcass is unforgiving. The load is manageable, but the back panel needs solid anchors or a stud to stay rigid.
10. HOOBRO Narrow Fluted Wall Cabinet: Best Farmhouse Style
HOOBRO Narrow Bathroom Wall Cabinet with Towel Rack, Space Saving Medicine Cabinet for Small Spaces, Farmhouse Fluted Wall Storage Cabinet with Adjustable Shelf, Natural
15.7 inch W x 7.9 inch D x 22.6 inch H
Wall-mounted
Engineered wood, stained natural
Enclosed storage, open shelf, towel bar
6.5 kg
Pros
- Narrow body maximizes vertical storage
- Enclosed storage plus open shelf and towel bar
- Adjustable shelf handles varied bottles
- Fluted front adds warmth to plain walls
Cons
- Assembly is time-consuming
- Included anchors are not suitable for drywall
- Paint can chip and doors hang unevenly
- Handles may clash with other hardware
This is the pick when the cabinet does decor work as much as storage work. The fluted farmhouse front in a natural wood stain warms up a plain wall in a way a flat white or mirrored unit does not.
It rates 4.2 stars across 139 reviews, and buyers call out the ideal small-bathroom size and the fluted look, with the unit feeling sturdy once assembled. Enclosed storage with an adjustable shelf, an open shelf and a bottom towel bar cover most of a powder room list.
Expect a longer assembly
Buyers describe assembly as time-consuming, with instructions that are not always clear, paint that can chip during the build and doors that may hang unevenly afterwards. Treat the stained finish gently, since a small ding is easier to hide than a cracked frame.
Which bathrooms suit it
It suits a farmhouse, cottage or transitional room with warm wood tones already in place, paired with white tile and matte black or brushed nickel fittings. Owners recommend buying better fixings than the ones included, since the supplied anchors do not suit drywall.
11. Spirich Compact Single Door Cabinet: Best Single Door Unit
Spirich Small Medicine Cabinet, Bathroom Wall Cabinet Over Toilet, White
18.7 inch W x 8.7 inch D x 20.6 inch H
Wall mount
Engineered wood, painted white
Two shelves, magnetic door
14.7 lb, 100 lb capacity
Pros
- Fits above toilets or beside vanities
- Two shelves with one adjustable
- 100 lb weight capacity
- Labeled parts and illustrated instructions
Cons
- Engineered wood less durable than metal
- Single door limits full interior access
- 14.7 lb body needs solid anchoring
This is the only unit in the roundup rated to carry 100 pounds, and that is a real spec advantage. The cabinet itself stops being the limiting factor, so a loaded family store becomes a mounting question rather than a cabinet question.
It scores 4.3 stars across 125 reviews, with 68 percent of ratings at five stars. Reviewers highlight the space-saving dimensions, hidden magnetic-door storage, adjustable shelving and a classic white style with decorative molding.
Depth is the number to check. At 8.7 inches this is one of the deeper bodies here, so it projects further into the room than a 5.5 or 6.5 inch unit. A single door also means you cannot see the full interior at once.
Where the weight rating helps
A 100 pound capacity means you can load it with a full shelf of medicines, paper products and backup supplies, so family bathrooms use it as the main store rather than a secondary one. The body is 14.7 pounds before contents, so it needs solid anchoring.
Material reality check
The carcass is FSC-certified engineered wood with a painted finish, and buyers note it is less durable than solid wood or metal in humid bathrooms. If your room has no working fan, running an exhaust fan during and after a shower protects the finish better than any coating.
12. Keonjinn Metal Framed Medicine Cabinet: Best Build for Damp Rooms
Keonjinn Black Bathroom Medicine Cabinet with Mirror 16"x26", Metal Framed
16 inch W x 5 inch D x 26 inch H
Surface or recessed mount
All metal frame and carcase
Two shelves and one drawer
Beveled mirror
Pros
- All-metal body resists rust and moisture
- Reversible door swing
- Recessed or surface mount
- Arrives fully assembled
Cons
- Shelves need unscrewing to reposition
- No soft-close damping
- Heavy enough to need two people
- 5 inch depth limits to flatter bottles
If your bathroom is genuinely steamy, this is the durability answer. The frame and carcase are metal rather than engineered wood, and the specification lists rust resistance, moisture resistance and shatterproof glass, a different material story from every other pick here.
It carries the highest average rating in the roundup at 4.8 stars, though across a smaller base of 81 reviews with 86 percent at five stars. Owners praise the build quality, the beveled mirror, the option to recess it, the reversible door and the fact that it arrives fully assembled.
What the metal build changes
An all-metal carcase does not swell, smell or delaminate the way MDF and particle board can, which is why we keep this pick despite the smaller review count. It also adds a drawer alongside two shelves, which no other unit here offers.
Where it holds back
At 16 inches wide, 26 tall and just 5 deep, the shallow profile keeps a door in front of it clear. But shelves require unscrewing rather than lifting out, there is no soft-close, and the unit is heavy enough to need two people unless it is recessed into the wall.
How to Measure Your Bathroom Wall Before You Buy
Measure before you shop, because a wall-mounted cabinet cannot be returned once the studs are marked. The whole check takes about two minutes and it decides recessed versus surface mount.
First, run a stud detector along the intended wall and measure the clear span between studs, typically 16 inches on center in a framed wall. A recessed cabinet must fit between those studs, so allow an inch of clearance on each side.
Second, measure cavity depth with a tape pushed past the drywall. Standard framed walls give roughly 3.5 to 4 inches between studs, which is why the Fundin recessed box above needs only a 3.3 inch opening.
Third, check the door swing. A 7 to 8.7 inch deep body can block a door that swings in from the same wall, and that problem is invisible until the cabinet is already hung.
Fourth, check faucet clearance above a vanity so the spout and the mirror do not compete, and so you can lift a bottle from the lowest shelf without hitting it. Fifth, confirm the wall type: plaster and lath in older homes crumble, and tile backer makes cutting risky.
Recessed vs Surface-Mount vs Corner: Which One Fits Your Room
Recessed sits flush inside the wall and takes up zero room but needs a cavity. Surface-mount hangs on the wall and protrudes roughly 4 to 8 inches. Corner units use dead floor space. Behind-the-door and narrow tower units use space nobody else is competing for.
Choose recessed when you have a framed wall with a cavity at the right height and you want the flattest profile possible. It is the only option that adds storage without adding depth, which is why recessed units with lighting are worth a separate look.
Choose surface-mount when the wall is thin, plaster, tiled or rented. It is the most forgiving install and the widest selection, and the trade is that 5 to 7 inch projection a door in front of it has to clear.
Choose a corner unit when every wall is occupied, and an over-the-toilet unit when the wall above the tank is unused. Check the tank dimensions before buying, since that mismatch causes the most wasted purchases in this category.
Installation Reality Check: What You Can Do and What Needs a Pro
Flat-pack wall cabinets in a small bathroom are a weekend job with a helper and a bad experience alone. The tight room is the difficulty, not the hardware.
You can handle a surface-mount install yourself if you have a stud, the right anchors and a second pair of hands to hold the unit level. Buyers report the supplied anchors are frequently unsuited to drywall, and a stud plus proper fixings beats any plug alone.
You need a professional for a recessed install in an older home. Homeowners in pre-1970 houses describe recessed cabinets as requiring a pro and sometimes a wall rebuild, and it is the most common installation regret mentioned on Reddit's r/BathroomRemodeling.
Renters have a workable path. One RV owner reported mounting a medicine cabinet with 3M mounting tape instead of screws with no problems after three years, which is a genuine option for a light cabinet on smooth painted drywall. Keep the load modest, since tape mounting does not suit a loaded cabinet.
Do not surface-mount over an existing recessed cabinet. Owners report a doubled depth and a half-finished look, and it is usually better to remove the old unit or refill and close the opening.
What to Use When You Have No Wall Space Left
When there is genuinely no wall left, a medicine cabinet is the wrong tool. These alternatives cover most remaining gaps in a small bathroom.
An over-the-toilet storage cabinet uses the dead band of wall above the tank. Measure the tank first, since that is where these units most often fail to fit, and our over-the-toilet storage guide covers the sizing in more detail.
A narrow tower or slimline floor cabinet uses a floor corner that a wall unit cannot reach. Floating or open shelves give a display surface with no door and no projection, at the cost of visible clutter and no concealed storage.
A slim wall mirror paired with a separate shelf splits the job, and if lighting is the deciding feature our recessed medicine cabinets with lights guide covers that category. For what hangs below the counter, our picks for floating vanities for small bathrooms are the other half of the storage problem.
Frequently Asked Questions
Are medicine cabinets in bathrooms outdated?
No. Medicine cabinets still earn their place because they store toiletries and double as the bathroom mirror in the same few inches of wall. What has changed is the shape of them: slim 5 to 7 inch bodies, corner units, behind-the-door designs and LED-lit mirrors have all moved up while deep builder-grade boxes have not.
What can I use instead of a medicine cabinet?
When a bathroom has no usable wall left, the practical alternatives are an over-the-toilet storage cabinet, a narrow tower or slimline floor cabinet, floating or open shelves, a separate wall mirror paired with a shelf, or a full mirrored wall panel with shallow storage. A corner unit works if the wall space is gone but a floor corner is still open.
What are the pros and cons of a recessed vs. surface-mount medicine cabinet?
A recessed cabinet sits flush inside the wall and adds no depth, but it needs a cavity of roughly 3.5 to 4 inches between studs, and older plaster or lath walls often do not have one. A surface-mount cabinet hangs on the wall, works on almost any wall including rentals, and offers a far bigger selection, but it projects 4 to 8 inches into the room and can block a door swing.
Where is the best place to put a medicine cabinet in the bathroom?
Above the sink or vanity is the best spot, because the mirror and the daily-use storage sit in the same place. The next best option is the wall directly above the toilet, which is usually empty and takes a wide shallow unit well. Avoid narrow gaps beside a tub where the door cannot open fully.
How far above the sink should a medicine cabinet be?
Mount it so the bottom edge sits roughly 6 to 8 inches above the faucet and the countertop, which keeps the mirror usable for a standing adult. Leave enough clearance to lift a tall bottle out of the lowest shelf without hitting the spout. A common working range is about 38 to 42 inches from the finished floor.
Conclusion: The Small Bathroom Medicine Cabinets Worth Buying in 2026
The best medicine cabinets for small bathrooms are the ones whose width and depth you measured against your own wall first. Our pick for most rooms is the Spirich corner cabinet, because it uses the one piece of space a wall unit can never reach, and it carries the strongest rating and review combination in the set.
If you have a usable wall, the Tangkula mirrored cabinet gives you the most storage per foot of wall and the Homleke barn door unit is the value answer with three tiers of shelving. In a damp room with no fan, the Keonjinn metal cabinet is the one that will not swell or smell over the years.
Measure the gap, find the studs, then pick. If you are still weighing mirrored or lit options, our medicine cabinets with mirrors guide goes deeper on that side of the category.
