A small bathroom is exactly where a medicine cabinet earns its keep. Instead of a mirror that only reflects, you get a mirror that also hides toothbrushes, razors, prescriptions and the collection of half-used bottles that otherwise ends up on the vanity top. The catch is that a poorly chosen cabinet can make a compact room feel even tighter. This guide walks through the formats that work in tight Canadian bathrooms, the scale and clearance rules that matter, and the visual tricks that make a small space read larger. When you are ready to compare options, our medicine cabinets collection ships Canada-wide.
Start with the wall, not the cabinet
Before you fall for a particular style, figure out what your wall can accept. Small bathrooms tend to fall into three situations.
- Interior wall with open stud bays: the best case. A recessed cabinet can sit between studs so the door finishes nearly flush with the wall, which is the single biggest space-saver available to you.
- Exterior wall: common in older homes from Halifax to Victoria, and in most Canadian climates the cavity is full of insulation and vapour barrier. Cutting into it is a bad idea for both heat loss and moisture control. Plan on a surface-mount cabinet here.
- Plumbing wall: vent stacks and supply lines often run directly behind the sink. If you cannot confirm what is back there, a surface-mount cabinet avoids an expensive surprise.
If you are unsure, a contractor can check with a stud finder and a small inspection hole. In condos and multi-unit buildings, strata or condo rules may restrict opening walls at all, so ask first.
Recessed, semi-recessed or surface mount
Each format trades depth against installation effort.
| Format | How much it projects | Best for | Trade-off |
|---|---|---|---|
| Recessed | Nearly flush | Tight rooms with a clear interior stud bay | Requires opening the wall; width limited by stud spacing unless framing is modified |
| Semi-recessed | Partial | Shallow cavities, or where you want a bit more storage than the wall depth allows | Still needs a wall opening; visible side panels |
| Surface mount | Full cabinet depth | Exterior walls, plumbing walls, rentals, tile you do not want to cut | Projects into the room; watch elbow and head clearance |
In a genuinely small bathroom, recessed wins whenever the wall allows it. Surface mount is no embarrassment, though: many modern units have slim profiles and mirrored sides so they disappear visually, and they are the realistic answer for a large share of Canadian bathrooms.
Scale rules that keep the room balanced
A cabinet that is too wide overwhelms a small vanity and a cabinet that is too narrow looks like an afterthought. A few reliable guidelines:
- Match the vanity width, or go slightly narrower. The cabinet should sit inside the visual footprint of the vanity below it. A single-sink vanity in a compact room pairs naturally with a single-door cabinet.
- Centre it on the sink, not the vanity. On an offset-sink vanity, centre the mirror on the basin so the person using it sees themselves straight on.
- Height follows the users. Place the centre of the mirror around eye level for the primary user, then check that the shortest user can still see their face. Taller cabinets add storage without adding width, which is exactly what a narrow room wants.
- Depth is the number people forget. In a bathroom where the vanity already crowds the door swing, every centimetre of projection counts. Look for the shallowest cabinet that still holds what you need.
Clearances to check before you buy
These are the practical checks that prevent the cabinet from being a daily irritation.
- Faucet and cabinet bottom: leave enough room above a tall or vessel-style faucet so the door clears it when it swings.
- Door swing: a door that opens toward a wall, a shower enclosure or a light fixture will hit it. Many cabinets offer reversible hinges; choose the swing that opens toward the open side of the room.
- Lighting: sconces beside the cabinet must not block the door swing. In a narrow room, integrated lighting or a fixture above the cabinet is often cleaner. Browse our wall sconces if you have the width.
- Wall-mount vanities: a floating vanity makes the floor read larger and pairs well with a recessed cabinet for a flush look. See our wall-mount vanities.
- Electrical: lit or powered cabinets need a nearby circuit. Look for CSA or equivalent Canadian certification marks, and have an electrician make the connection to your provincial electrical code.
Visual tricks that make a small bathroom feel bigger
- Frameless or slim-frame doors read as pure mirror, which is what enlarges the room. Heavy frames chop up the reflection.
- Mirrored interiors and mirrored door backs bounce light around when the cabinet is open and give you a rear-view for grooming.
- Full-height mirror doors on a tall, narrow cabinet stretch the wall vertically and draw the eye up.
- Integrated LED lighting replaces a separate vanity light, removing one more object from a crowded wall. Add a defogger if ventilation is weak, which is common in older Canadian homes in winter when windows stay shut.
- Colour-match the cabinet sides to the wall on surface-mount units so only the mirror registers.
If the storage is not worth the projection, a plain mirror and a slim shelf can be the better call. Our bathroom mirrors collection covers that route.
Picks by tier
Rather than naming models, here is how the category breaks down across the brands we carry.
- Entry and mid-range: aluminum or steel bodies, single or double mirror doors, adjustable glass shelves and usually reversible hinges. This is where surface-mount cabinets shine, and a sensible choice for rentals and secondary bathrooms. Kohler offers compact cabinets in this range in a variety of widths.
- Premium: integrated LED lighting, defoggers, interior outlets and soft-close hinges become standard, and recessed options widen. Duravit and Kohler both have lit cabinets that suit a narrow room.
- Specialist: Swiss-made cabinets from Sidler are the reference point: precise recessed installations, double-sided mirror doors, lighting built into the body and very slim profiles, which is exactly what a small bathroom rewards.
Pricing is in Canadian dollars and varies by brand, size and features, and a recessed installation adds labour that a surface mount does not. Trade customers can ask about the Vatero trade program for project pricing.

Frequently asked questions
Can I install a recessed medicine cabinet in an exterior wall in Canada?
It is strongly discouraged. Exterior walls in Canadian homes carry insulation and a vapour barrier, and cutting a cavity into them creates a cold spot, condensation risk and a break in the air barrier. Use a surface-mount or semi-recessed cabinet on exterior walls, and save recessed installations for interior partitions.
How wide should a medicine cabinet be for a small vanity?
Keep the cabinet the same width as the vanity or slightly narrower, and centre it on the sink. In a narrow room, gain storage by choosing a taller cabinet rather than a wider one, so the unit stays within the vanity's visual footprint.
Is a lit medicine cabinet worth it in a tiny bathroom?
Often yes. An integrated light removes the need for a separate vanity fixture, which frees up wall space and reduces clutter. Confirm the unit carries a Canadian certification mark, and have the wiring done by a licensed electrician to your provincial code.
Do medicine cabinets ship across Canada?
Yes. We ship medicine cabinets to every province and territory, from British Columbia to Newfoundland and Labrador. Recessed units are lighter than they look; larger lit cabinets may ship as oversized parcels, so check the shipping details on the product page before ordering.
