A good bathroom lighting layout always comes down to three layers working together: ambient, task, and accent. Space recessed fixtures using the ceiling height divided by two rule, size the vanity light to the mirror, and only install wet-rated fixtures over a shower or tub. The Versa 3" Recessed Modular Downlight is a solid starting point for the ambient layer in most bathrooms.
TL;DR:
- Recessed lighting should be spaced roughly half of the ceiling height apart, with specific distances: four feet for an eight-foot ceiling, and five feet for a ten-foot ceiling.
- The vanity light should be approximately 75% to 100% of the mirror’s width, mounted just above the glass, with two sconces on either side for even cross-illumination.
- Fixtures over showers or tubs require wet ratings of IP65 or higher, with proper certification and early planning to avoid costly relocations after drywall.
- Use ambient fixtures that spread light evenly across the room, avoiding placement directly over the vanity mirror to prevent shadows.
- Smaller bathrooms benefit from single low-profile fixtures with layered lighting focused on the vanity and critical zones, rather than multiple recessed fixtures.

Understanding the three lighting layers
Ambient light fills the room evenly, usually from a ceiling fixture or recessed downlights. Task light handles grooming at the mirror, where you shave, apply makeup, or check your skin tone in detail. Accent light is the extra layer, a niche light in the shower, a soft glow under a floating vanity, or a night light for late hours.
- Ambient: overall ceiling fixtures or recessed pots spread evenly across the room
- Task: vanity sconces or a linear bar mounted at mirror height for shadow-free grooming
- Accent: shower niches, toe-kick strips, or backlit mirrors for mood and safety at night
Aim for roughly 70 to 100 lumens per square foot of general bathroom illumination, with more concentrated at the mirror where fine detail matters. A bathroom around 60 square feet lands somewhere near 4,200 to 6,000 lumens total before you add extra punch at the vanity.
For colour, stick to 2700K to 3000K for a warm, flattering tone, and look for a CRI of 90 or higher so skin tones and makeup read true rather than washed out or grey. Before buying anything, confirm the fixture’s rating matches its location and check for a CSA or cULus mark on the packaging or spec sheet.
How far apart should recessed lights be in a bathroom?
A simple rule gets you most of the way there: divide your ceiling height in half, and that’s roughly how far apart your recessed fixtures should sit from each other and from the walls.
- 8-foot ceiling: space pots about 4 feet apart, keeping them 2 feet from walls
- 9-foot ceiling: space pots about 4.5 feet apart for even coverage
- 10-foot ceiling: space pots about 5 feet apart, since the extra height spreads light wider
Lower ceilings call for smaller trims, often 4 inches, to avoid a bulky look, while taller ceilings can handle 5 or 6 inch housings without feeling heavy. A baffle trim softens glare in a small room, while a reflector trim pushes more light into a larger one.
One placement mistake shows up again and again: a recessed pot centred directly over the vanity mirror. The downward angle throws shadows under the eyes, nose, and chin, the opposite of what you want at a mirror. Shift ambient recessed fixtures away from the mirror zone and let a dedicated vanity light carry the task layer instead.
Pro Tip: Mark your recessed layout on the ceiling drywall with chalk before cutting, then stand under each mark to check it clears joists and existing plumbing runs.
Sizing and placing your vanity light
The vanity light does the real work in a bathroom, and getting its size and position right makes the difference between a flattering mirror and a shadowed one.
- Choose a fixture roughly 75% to 100% as wide as your mirror for balanced coverage
- Mount a single bar centred above the mirror at a height that clears the glass by a few inches
- Favour two sconces, one on each side of the mirror, for true cross-illumination
- Set side sconces at roughly eye level, often close to 65 to 70 inches from the floor, adjusted for the household’s typical height
Frontal, cross-angled light from both sides of a mirror is widely recommended over a single overhead fixture because it lights the face evenly and avoids the shadows that downward light creates, a point echoed in Natural Resources Canada’s home lighting guide. A single top-centre bar still works in tighter spaces, but it rarely matches the evenness of two-sided light.
For a deeper walkthrough of fixture styles and mounting heights, our best bathroom vanity lights guide and our vanity light sizing guide both cover specific fittings in more detail, and our bath vanity collection and illuminated mirrors are worth a look for anyone planning a mirror and light together.
Lighting a shower or tub safely
The Canadian Electrical Code sorts bathroom areas into dry, damp, and wet locations, and the fixture you choose has to match where it’s going. Most of a bathroom ceiling counts as a damp location, while the space directly over a shower or tub counts as wet.
- General bathroom ceilings need fixtures rated IP44 or better for damp locations
- Anything mounted directly over a shower or tub needs a wet rating of IP65 or higher
- Always confirm a CSA or cULus mark alongside the IP number, since a high IP rating alone doesn’t guarantee Canadian certification
A sealed, gasketed recessed trim is the standard choice for over-shower installations, and a sealed surface flush mount works well for a damp ceiling nearby. Planning fixture rough-ins before the walls are closed up saves real money. Moving a sconce or recessed can after drywall goes up is far costlier than getting the layout right at framing stage, so loop in a licensed electrician early if you’re touching wiring near a wet location. Our IP65 shower rating guide and ceiling and recessed collection are good next stops for matching fixtures to each zone.
Adjusting the layout for small bathrooms and primary ensuites
A powder room or small ensuite doesn’t need the same fixture count as a primary bath, and cramming in too many pots makes a small ceiling feel busy rather than bright.
- Use one low-profile flush or semi-flush fixture for ambient fill instead of multiple recessed pots
- Put most of your lumen budget at the vanity, where the room actually gets used
- In a primary bath with a separate shower, treat each zone (vanity, tub, shower) as its own lighting decision rather than one blanket plan
- For a pocket shower or a bathroom with a skylight, layer in a dimmer so daytime glare and evening darkness both have a comfortable setting
A compact flush mount centred in a small room, paired with a well-sized vanity light, usually outperforms a scattered grid of mini recessed pots. Our small bathroom lighting guide walks through a few more compact layouts, and our flush mounts collection is a practical place to browse options sized for tighter ceilings.
Finishing touches that make a bathroom feel complete
Matching your lighting finish to your faucet and cabinet hardware pulls the whole room together instead of leaving fixtures feeling like an afterthought. A warm brass vanity light paired with brass faucets and pulls reads intentional, while mixing several unrelated finishes in one small room tends to feel scattered. The Roux Wall Sconce is a good example of a finish that pairs easily with most hardware families. For readers also rethinking the door and trim, coordinating finishes across doors and fixtures is worth a look at the same time.
- Add a dimmer to your vanity light for a softer evening setting
- Consider a backlit mirror for gentle, even task light without a separate sconce
- A toe-kick LED strip gives safe night lighting without flipping on the main fixtures
Pro Tip: Run LED strip wiring inside the toe-kick channel before the vanity cabinet is installed, so the connection stays hidden and accessible for future bulb swaps.
Why it’s worth planning with a lighting specialist
A well-planned layout prevents the two mistakes that cost the most to fix later: putting a fixture in the wrong rating zone, and locating boxes before the mirror and vanity size are settled. Our showroom and curated catalogue exist partly to catch these problems before drywall goes up, since swapping a damp-rated fixture for a wet-rated one after installation almost always means cutting into a ceiling again. A short consultation at the framing stage, paired with our vanity and shower lighting guides, tends to save far more time than it costs.

A few fixtures worth starting with
For readers piecing together a layout, a few fixtures cover the three layers without overcomplicating the plan.
- Glaze Large Flushmount: a low-profile ambient fixture suited to standard and lower ceilings
- Versa 3" Recessed Modular Downlight: a compact recessed option for even ambient spread
- Roux Wall Sconce: a flexible task light for vanity cross-illumination or accent placement
| Fixture | Layer it serves | Where it fits |
|---|---|---|
| Glaze Large Flushmount | Ambient | Ceiling centre, low to standard ceiling heights |
| Roux Wall Sconce | Task | Either side of the vanity mirror |
Pro Tip: Buy the vanity light first, then choose ambient fixtures that complement its finish rather than the other way around.
Checking fixture ratings before purchase matters more than most renovators expect: an IP65 rating is the minimum for anything mounted directly over a shower or tub.
Plan the vanity light first, confirm the wet and damp zones second, and fill in ambient coverage last.
Browse our full ceiling lighting, wall lighting, and table lamps selection, our cabinet and bathroom hardware for coordinating finishes, or our fans and furniture and decor if you’re planning the whole room at once.

FAQ
How do I lay out bathroom lighting?
Confirm every fixture near a shower or tub carries a wet rating before installing it.
What is the most flattering lighting for a bathroom?
Frontal, cross-angled light from sconces on both sides of the mirror tends to flatter the face more than a single overhead fixture, since it avoids the downward shadows that recessed pots create, a point supported by Natural Resources Canada’s lighting guide. Pair that with a warm 2700K to 3000K colour temperature and a CRI of 90 or higher for accurate skin tone.
What is the rule for spacing recessed bathroom lights?
Divide your ceiling height by two to get the rough spacing between fixtures and from the walls. An 8-foot ceiling suggests about 4 feet of spacing, while a 10-foot ceiling allows closer to 5 feet.
What’s trending in bathroom lighting right now?
Backlit and illuminated mirrors, warm dimmable LEDs, and layered finishes that match cabinet hardware are showing up in more current bathroom designs, alongside a continued shift away from a single bright ceiling fixture toward distributed layers.
Do bathroom lights need to be GFCI protected?
Bathroom circuits, including lighting near sinks, showers, and tubs, typically require GFCI protection under Canadian electrical rules, and any wiring near a wet location should be confirmed with a licensed electrician rather than assumed safe.
