The best bathroom wall lights are a matched pair either side of the mirror, centred at about 1.6 metres from the floor, IP44 rated, 3000K, with opal or frosted glass, on their own switch. That one decision does more for a bathroom than any ceiling light, because it is the light you see your own face by. Everything else on the wall, the up-and-down light on the far wall, the picture light over the bath, the low-level marker light, is a second layer, and a good one.
Wall lights are the most under-fitted item in the British bathroom. Most rooms have a ceiling light and nothing else, which is why most people think they look tired in their own bathroom and fine in a hotel. The hotel has wall lights. We have sold lighting for 41 years and if we could change one thing about the average bathroom it would be this.
The four kinds of bathroom wall light
| Type | What it does | Where |
|---|---|---|
| Mirror-side wall light | Lights the face from both sides, no shadows under the eyes or nose | Either side of the mirror, at eye level. The one that matters |
| Over-mirror light | A bar or tube above the mirror, washes down the face | When there is no wall space either side. Second best, but far better than nothing |
| Up-and-down wall light | Throws light up the wall and down it; ambient, not task | The wall opposite the mirror, beside the bath, a wet room. Adds height and softness |
| Low-level and marker lights | A pool of light at skirting height | Beside the bath, along a wet room wall, for the 2am visit without the ceiling light |
The pair at the mirror, and why it beats the ceiling
Light from above drops shadows into the eye sockets and under the nose and chin, which is why a bathroom lit by a single ceiling fitting makes everyone look ten years older at 7am. Light from the sides at face height fills those shadows in. That is the entire trick of the theatre dressing room, and it costs two wall lights. Fit them so the centre of each light is at roughly eye height, 1.5 to 1.7 metres from the floor for most households, and 600 to 900mm apart, either side of the mirror. If the mirror is wide, a light at each end; if it is narrow, a light each side of the frame.
Put them on their own switch, separate from the ceiling. The face light is what you want at the mirror; the ceiling wash is what you want when you are cleaning the floor. They are different jobs, and a bathroom with both on one switch is always too bright for one and too dim for the other. The detail on mirror lighting, including the over-mirror alternative and illuminated mirrors, is in bathroom mirror and vanity lighting.
What rating a bathroom wall light needs
A wall light beside the basin is almost always in zone 2, the 0.6 metre band around the bath, shower and basin, which means it needs a minimum of IPX4 under the wiring regulations. IP44 is the rating to buy, and it is what every fitting in our bathroom wall light range carries. Directly over a bath, within 2.25 metres of the floor, is zone 1 and needs IPX4 too, or IPX5 where a shower jet could reach it; IP44 covers the first and IP65 the second. A wall light on the far wall of a large bathroom may technically sit outside the zones, but buy IP44 anyway. Steam finds the fitting whether or not the regulations say it is there. The zone map and the electrician question are in bathroom lighting zones and IP ratings, and the wider IP44 or IP65 decision is in IP65 vs IP44.
Glass, Kelvin and colour rendering
- Opal or frosted glass. The light has to be soft to be flattering. A clear glass wall light beside a mirror shows you the bulb and your reflection shows you the bulb again. Opal, always, unless the lamp is a decorative filament on a dimmer.
- 3000K. Warm enough to be a home, clean enough to keep white tiles white and to match daylight through the window. 2700K is fine if the rest of the house is 2700K and the room has no strong daylight. 4000K is for a clinic.
- CRI 90 at the mirror. This is the one place in the house where colour rendering is worth paying for, because you are matching make-up and judging your own skin. Astro's integrated LED wall lights are CRI 90; a standard replaceable lamp is 80. What CRI is explains the number.
- Dimmable. Most bathroom wall lights are, on a compatible dimmer. It turns the same two fittings into the evening light for the bath.
Which style for which bathroom
Match the finish to the taps, not to the ceiling light. Chrome with chrome, brushed nickel with nickel, brass with brass or unlacquered brass if you want it to age. In a period bathroom with a roll-top bath, a traditional wall light with a bell or fluted glass shade, in brass, on a dimmer, is the whole look; Elstead's Dryden and Quintiesse's Ashland Bay do it properly and both are IP44. In a modern or hotel-style room, a slim tube or a flat opal panel, Astro's Zeppo, Bari or Roma, disappears into the wall and lets the light do the work. In a small bathroom go slim and flat, because a projecting wall light beside a narrow basin is the thing you knock with your elbow every morning; the small bathroom guide covers the rest.
The second layer: up-and-down lights and low-level light
Once the mirror is sorted, the far wall is the next place light belongs. An up-and-down wall light, or a pair, on the wall opposite the mirror or beside the bath throws light up the wall to the ceiling and down towards the floor, and it does two things a ceiling light cannot: it makes the room feel taller, and it gives you a light for the bath that is not in your eyes. Astro's Kyoto is an IP44 up-and-down light built for exactly this. Lower still, a marker light at skirting height beside the bath or along a wet room wall is the light for the middle of the night, and a good scheme has all three: face, wall, floor. That layering is set out in the complete guide to bathroom lighting, and the ceiling light that goes with it is in the best bathroom ceiling lights.
What we would overrule you on
- One wall light, off to one side of the mirror. It lights half your face and shadows the other. Two, or an over-mirror bar. Never one.
- A wall light above the mirror when there is room beside it. Above is the fallback for a narrow wall. If there is 200mm either side of the frame, use it.
- Wall lights wired to the ceiling switch. Separate switch, or a dimmer, or you will never use them properly.
- A clear-glass wall light with a visible LED beside a mirror. You will see the bulb twice and your face not at all.
- Matching the wall lights to the ceiling light rather than the taps. The taps are at eye level next to the wall lights. The ceiling light is not.
The bathroom wall lights we would fit
- Astro Zeppo Wall: a flat opal-glass drum in chrome, IP44, dimmable, and about as close to a universal bathroom wall light as exists. Slim enough for a narrow basin wall.
- Astro Roma: a small, sharp cylinder in matt gold, chrome or black, for the modern bathroom that wants the fitting to be part of the design.
- Astro Bari: the simple opal cylinder that suits everything and costs less than you expect. Buy two.
- Endon Ashbury: a chrome-and-clear-glass traditional lantern shape at IP44, for the period bathroom on a budget, on a dimmer with a filament lamp.
- Quintiesse Ashland Bay: a natural brass four-light bar with opal shades, IP44, the over-mirror fitting for a wide mirror in a house with brass taps.
- Elstead Dryden: a polished brass wall light with a fluted glass bell shade, IP44, the classic beside a roll-top bath, on a dimmer with a filament lamp.
The short version
- A matched pair either side of the mirror at eye level is the single best change you can make to a bathroom. On their own switch.
- IP44 for every bathroom wall light; the mirror wall is zone 2 and IPX4 is the legal minimum. IP65 only if a shower jet can reach it.
- Opal glass, 3000K, CRI 90 if the LED is built in, dimmable.
- Match the finish to the taps. Slim and flat in a small room.
- Then add the second layer: an up-and-down light on the far wall and a low-level light for the night.
Frequently asked questions
Where should bathroom wall lights be positioned?
Either side of the mirror with the centre of each light at eye level, roughly 1.5 to 1.7 metres from the floor, and 600 to 900mm apart. If there is no wall space beside the mirror, a bar above it is the fallback. Up-and-down wall lights go on the wall opposite the mirror or beside the bath.
Do bathroom wall lights need to be IP rated?
Beside the basin or bath, yes: that is zone 2 under BS 7671 and the minimum is IPX4, so buy IP44. Directly over a bath within 2.25 metres of the floor is zone 1, also IPX4, or IPX5 where a shower jet can reach. On a far wall outside the zones there is no legal minimum, but IP44 is still the sensible buy.
How many wall lights should a bathroom have?
Two at the mirror as the minimum, one each side. A larger bathroom adds one or two up-and-down lights on the far wall or beside the bath, and a low-level light for the night. A single wall light beside a mirror is the one arrangement to avoid.
What is the most flattering lighting for a bathroom mirror?
Light from both sides at face height, in warm white at 3000K, from opal or frosted glass so it is soft, with a colour rendering index of 90 if you can get it. Overhead light alone drops shadows into the eyes and under the chin.
Should bathroom wall lights match the ceiling light?
Match them to the taps and the mirror frame instead, because those sit at the same eye level. Chrome with chrome, brass with brass. The ceiling light can be a plain opal flush fitting in any finish and nobody will notice.
Can you put a wall light above a bath?
Yes, if it is rated IPX4 or better, which any IP44 bathroom wall light is, and it sits above the bath within zone 1 up to 2.25 metres from the floor. Where a shower is over the bath and a jet could reach the fitting, use IP65. Inside the bath itself is zone 0 and no wall light is allowed.
