Vanity Lighting Placement: Height, Spacing & What Most People Get Wrong

Vanity lighting gets more attention paid to its style than any other fixture in the bathroom - the finish, the shape, whether it matches the faucet - and less attention paid to the two variables that actually determine whether it works: mounting height and spacing relative to the mirror and the face using it. A beautifully finished sconce mounted at the wrong height still throws shadows across the eyes. A well-reviewed light bar centred on the wrong point still leaves half the mirror dim.

This is also the step most renovation guides skip entirely, because it isn't a shopping decision - it's a measuring one. This guide gives the concrete numbers Canadian bathrooms need: the exact height range for sconces and light bars, the spacing formula for single and double-sink vanities, the colour temperature and CRI figures that actually matter, and the code requirements around damp ratings and GFCI protection that apply regardless of which fixture you choose.

If you haven't chosen your vanity or mirror yet, start with our complete bathroom vanity buying guide for Canada - it covers sizing, materials, and countertops before you get to lighting. This page assumes you already know, or are close to knowing, your vanity and mirror width, and focuses entirely on where the light goes.

Six rules cover essentially every vanity lighting placement decision. Get these right and the fixture you choose becomes a style question, not a functional gamble.

Mounting height is the single most common vanity lighting mistake in Canadian bathrooms, and it's almost always the same error: fixtures installed too high, at whatever height the previous builder-grade strip light happened to occupy, rather than at a height chosen for the person actually using the mirror. The fix is a genuinely simple rule - task lighting at a vanity should land at eye level, because that's the angle that lights a face evenly instead of from above.

This is also why so many existing Canadian bathrooms feel dimly or harshly lit despite having a working fixture: the light is there, but it's mounted at a height that was convenient for the original wiring rather than correct for the face beneath it. Correcting height on an existing switched box is often a straightforward fixture swap - see our guide to installing a bathroom vanity in Canada for the adjacent plumbing and mounting considerations if you're tackling both at once.

Once height is set, spacing is the number that determines whether light actually falls evenly across the face rather than clustering to one side. For a pair of wall sconces flanking a mirror, the workable range is 24-36 inches apart on-centre, and the spacing should be centred on the sink and the face using it - not on the vanity cabinet as a whole. That distinction matters most on offset sinks, vessel-sink vanities, and any layout where the sink isn't dead-centre on the cabinet.

A single recessed ceiling light or pot light positioned directly above the mirror is the most common vanity lighting setup in Canadian homes, and it's also the least functional one for the task actually performed at a vanity. Light falling straight down from above the head lands on the top of the face and casts shadows downward, under the eyes, along the sides of the nose, and beneath the chin - precisely the angle that makes shaving nicks and uneven makeup application more likely, because the person can't see their own face clearly.

This isn't an argument against ceiling lighting - it plays a legitimate role as ambient, whole-room illumination. The problem is relying on it as the only light source at the mirror. A vanity needs dedicated task lighting that hits the face from the sides or straight on at face height, which is exactly what wall sconces, a properly placed light bar, or an LED-backlit mirror are built to do.

All three fixture types can light a vanity correctly - the difference is how much placement precision each one demands from you, and how much electrical work each involves.

For a renovation where the electrical is already open, sconces give the most classic, layered look and are worth the extra placement care. For a refresh where you'd rather not add or move wiring, an LED-backlit mirror is usually the simpler upgrade - it replaces the mirror and the light source in one product, at the power point that's often already there. Bathify's LED Mirrors collection - including the ICO Bath Iris and Denver lines detailed further down this page - is built specifically to solve this without a placement calculation.

A single-sink vanity has one lighting zone: centre the fixture (or fixture pair) on the sink and mirror, and the rest of this guide applies directly. A double-sink vanity is functionally two vanities sharing one countertop, and the lighting should treat it that way - each sink gets its own centred lighting zone, rather than one central pair of sconces awkwardly serving both users from the middle of the cabinet.

In practice this usually means one of two approaches: two matching LED mirrors, one per sink, each centred on its own sink and lit independently; or a continuous light source - a wide light bar or a run of sconces - that spans both zones evenly rather than concentrating light in the centre of the vanity where neither sink actually sits.

Colour temperature, measured in Kelvin (K), describes how warm or cool a light source looks - not how bright it is. For a bathroom vanity, the practical range worth choosing from is 2700K to 4000K. At the lower end, 2700-3000K reads warm and cozy, close to a traditional incandescent bulb, and suits bathrooms where the fixture is also meant to feel comfortable at night. At the upper end, 3500-4000K reads neutral to cool, closer to daylight, and is generally considered better for precise tasks like matching makeup shades or a close shave, because it renders detail more crisply.

Colour temperature alone doesn't guarantee accurate colour, though - that's what CRI (colour rendering index) measures. CRI scores a light source from 0-100 on how faithfully it reveals true colours compared to natural daylight. A budget fixture can carry a flattering-sounding Kelvin rating and still have a low CRI, which shows up as skin looking slightly duller, greyer, or off compared to how it actually looks in daylight. For a vanity specifically, aim for a CRI of 90 or higher - it's the difference between makeup that looks right at the mirror and looks wrong the moment you step outside.

Placement and style aside, every fixture installed near a bathroom sink or vanity in Canada has to meet a basic safety requirement: it needs to be rated for a damp location under the Canadian Electrical Code, and anything installed inside or directly above a shower or tub zone needs a wet rating instead. This isn't a style consideration - it's the difference between a fixture that lasts and one that corrodes or shorts out from ordinary bathroom humidity within a couple of years. Product listings and specification sheets will state the rating directly; if a fixture doesn't mention one, treat that as a reason to check before buying, not assume it's fine.

Height and spacing cover the two biggest errors, but a handful of smaller decisions reliably undermine an otherwise correct layout.

A 3000K sconce pair next to a 5000K ceiling pot light reads as mismatched even when each fixture is individually fine - the eye notices the contrast immediately. Keep every fixture in the bathroom within a similar Kelvin range, even if they come from different collections.

Many Canadian homes built in the 1980s and '90s have builder-grade strip lights mounted well above the eye-level range described earlier, often 74-80 inches up. It's tempting to reuse that exact spot when replacing the fixture - resist it, and remeasure to the 60-65" range instead.

A fixed-brightness vanity light is either too harsh for a 2 a.m. bathroom trip or too dim for a careful morning shave. A dimmer switch, or a fixture with built-in adjustable brightness like an LED mirror's touch controls, solves both without needing two separate light sources.

A standard interior-rated fixture is usually cheaper than its damp-rated equivalent, which makes it tempting to substitute one for the other. It's a false saving - a fixture not built for bathroom humidity tends to fail within a few years, at which point the "savings" have been spent twice.

Run through this before you buy or install. If every box is checked, the fixture itself becomes a style decision rather than a functional risk.
