Medicine cabinets look like a simple purchase until you actually start shopping. Recessed or surface mounted? Lighted or plain? One door or three? The choice gets much easier when you answer four questions in the right order: what your wall allows, who uses the bathroom, which feature tier you really need, and only then, what style suits the room. Work through them in sequence and a full medicine cabinet collection narrows itself to a shortlist in about ten minutes.
Question 1: What will your wall allow?
Space comes first because it eliminates more options than any other question. Medicine cabinets come in three mounting types, and your wall usually decides which ones are on the table.
- Recessed cabinets sit inside the wall cavity, so only the mirror and a slim frame project into the room. They look built in and keep a small bathroom feeling open, but they need an empty cavity: no plumbing stack, no wiring, no ductwork behind the drywall. In a wood-framed house that is often achievable. In a concrete-walled condo tower in Vancouver or Toronto, it usually is not.
- Semi-recessed cabinets sink partway into the wall and project the rest. They are the sensible compromise when the cavity is too shallow for full recessing.
- Surface-mounted cabinets fasten to the finished wall, no cavity required. They install almost anywhere, including over tile, and they are the default for concrete walls, rentals and any wall you would rather not open up.
One caution specific to Canadian homes: think twice before recessing into an exterior wall. That cavity is where your insulation and vapour barrier live, and carving a cabinet-sized void into a wall that faces a Prairie winter invites cold spots and condensation. On an exterior wall, semi-recessed or surface-mounted is the safer route, and it is worth a conversation with a contractor who knows your local building requirements before anyone cuts drywall.
Before you browse, take three measurements: the width of your vanity or sink, the height available between backsplash and ceiling or light fixture, and, if you hope to recess, the usable depth and stud spacing inside the wall. A cabinet the same width as the vanity below it, or slightly narrower, almost always looks intentional. One that is wider rarely does.
Question 2: Who is using this bathroom?
The second question sorts out size, door count and interior layout.
- A shared family bathroom earns a wide double-door or triple-door unit with adjustable shelves, so two people can claim their own side and morning routines do not collide.
- A couple's ensuite is where interior extras pay off: mirrored door backs for a three-way view, an interior outlet for a toothbrush or shaver, and deep shelves for the bottles that never seem to shrink in number.
- A bathroom kids use argues for a mounting height adults can reach comfortably, and ideally an upper shelf or compartment that keeps medications well away from small hands.
- A powder room often does not need a medicine cabinet at all. There is little to store, and a well-chosen piece from a bathroom mirror collection will do more for the room than a shallow cabinet opened twice a year.
Question 3: Which feature tier do you actually need?
Rather than anchoring on a dollar figure, think in tiers, because the jump between tiers is about features as much as materials.
| Tier | What you typically get | Best suited to |
|---|---|---|
| Entry | A mirrored box with basic shelves and simple hinges | Secondary baths, rentals, tight budgets |
| Mid-range | Rust-resistant aluminum bodies, soft-close hinges, adjustable glass shelves, mirrored interiors | Most primary bathrooms |
| Premium | Integrated LED lighting with dimming, mirror defoggers, interior outlets, refined engineering from specialist manufacturers | Ensuites and forever homes |
Two Canadian notes here. First, any lighted or electrified cabinet sold for our market should carry a recognized certification mark such as CSA or cUL. If a listing is silent on certification, treat the silence as your answer. Second, hardwired lighting means an electrician. Electrical requirements vary by province, so budget for the installation as well as the cabinet and let a licensed local professional handle the connection.
Humidity deserves a thought at every tier. A cabinet lives in steam daily, so protected interiors and quality hinges are not luxuries. They are the difference between a cabinet that ages gracefully and one that shows rust streaks within a few seasons.
Question 4: What style finishes the room?
Style comes last on purpose. Once mounting type, size and tier are fixed, the remaining choices are genuinely aesthetic and hard to get wrong. Frameless cabinets all but disappear into the wall and suit contemporary rooms, especially alongside the clean lines of modern vanities. Framed cabinets bring warmth to traditional and transitional bathrooms; match the frame finish to your faucet and hardware, whether that is chrome, brushed nickel or matte black, and the room reads as planned rather than assembled.
Red flags to watch for in listings
- A "recessed" cabinet with no rough-in opening dimensions published. Without them you cannot know whether it fits your wall.
- Lighted models that never name a certification mark.
- Vague material descriptions such as "metal body" with no mention of rust resistance.
- No word on door swing or hinge reversibility. A door that opens against the shower or an adjacent wall is a daily annoyance.
- Photos that never show the interior. Shelf count and adjustability matter more than another angle of the mirror.
- Unclear delivery terms. Mirrored cabinets ship as fragile goods, and a Canadian retailer should be upfront about shipping across the country, from Vancouver to Halifax, before you reach checkout.
The final checklist
- Confirmed the mounting type your wall supports, and avoided recessing an exterior wall.
- Measured width, height and, for recessed models, cavity depth and the rough-in opening.
- Matched door count and interior layout to the people using the room.
- Verified CSA or cUL certification on any lighted model, and budgeted for an electrician if it is hardwired.
- Checked door swing, hinge reversibility and shelf adjustability.
- Confirmed delivery terms and the return policy for mirrored goods.
Run every candidate through that list and the weak options remove themselves. For the rest of the room, from vanity pairing to lighting layers, our bathroom and kitchen guides cover the renovation one decision at a time.
Frequently asked questions
Is a recessed or surface-mounted medicine cabinet better?
Neither is better in the abstract. Recessed looks built in and saves space, but it needs an empty interior wall cavity and some carpentry. Surface-mounted installs almost anywhere and is the practical pick for concrete-walled condos, rentals and finished bathrooms you do not want to open. Choose the one your wall makes easy.
Can I recess a medicine cabinet into an exterior wall?
In most of Canada it is a poor idea. Exterior wall cavities hold insulation and the vapour barrier, and removing a cabinet-sized block of both invites heat loss and condensation. If the only available wall is an exterior one, go semi-recessed or surface-mounted, and check with a local contractor about your provincial requirements first.
Do lighted medicine cabinets need an electrician in Canada?
Plug-in models only need a nearby outlet, though the cord run should be tidy and safe. Hardwired models tie into your bathroom circuit and should be installed by a licensed electrician working to your provincial electrical code. Either way, look for a CSA or cUL mark on anything electrified before you buy.
What size medicine cabinet should I buy?
Choose a cabinet the same width as your vanity or a little narrower, centred over the sink. For height, make sure the mirror covers eye level for both the tallest and shortest adults in the household. If you are recessing, remember that the rough-in opening, not the outer mirror dimension, is the number that has to fit your wall.
