How to Properly Light a Bathroom for Function and Design

We’ve been finalizing the design plans for our primary bath, and lately I’ve had lighting on my mind. Lighting can make or break a bathroom- both aesthetically and functionally. Whether you’re renovating or refreshing, proper bathroom lighting is key for creating a space that not only looks beautiful but also works hard in your daily life. From selecting the right bulb temperature to placing the right fixtures in ideal spots, I’m sharing practical tips that I use to help you confidently light your bathroom like a designer. Let’s dive in!

If you’ve been following along, you already know one of my non negotiable bathroom fixtures is an exhaust fan and light combo. I shared a post last month with all the details… but what other types of fixtures should a bathroom include? There is nothing worse than a poorly lit bath. When I’m getting ready in a space with inadequate light, it really makes me appreciate having good lighting here at home. These are my best suggestions…

Why Bathroom Lighting Matters

Good lighting enhances the overall bathroom design, emphasizes architectural elements & tile, makes daily tasks easier, and even flatters your reflection offering a confidence boost (yes please!). Since bathrooms are high-functioning spaces in every home, it’s important to strike a balance between recessed, ambient, task, and accent lighting. I always aim to layer light fixtures in a way that feels thoughtful, warm, and intentional.

The Four Types of Bathroom Lighting

Layered lighting is the key to every well-lit bathroom. Here’s a quick breakdown of the four types of fixtures I always include…

Recessed Lighting

I know can lights get a bad rep, but recessed lighting is imperative to evenly lighting a bathroom. I’ll always choose a recessed exhaust light over a clunky traditional exhaust with a grille. Check out this post for my thoughts on why an exhaust fan & light combo is the best choice! It’s functional with a streamlined aesthetic.

Advice: Always put your recessed lighting on a dimmer or separate switch- that way you have more control and can rely on them as needed. Don’t need to go crazy with too many cans… in a small bath, sometimes one is enough.


Ambient Lighting

This is your overall light source- what fills the room with illumination. These can be a variety of fixtures…

  • Flush mount fixtures
  • Semi-flush mount fixtures
  • Pendants
  • Integrated lighting in architectural features (like skylights)
  • Chandeliers

Designer tip: Avoid harsh overheads as your only light source. They cast unflattering shadows and don’t offer enough task support.


Task Lighting

This is where most people go wrong… task lighting is essential for grooming and your daily routine. Here are some easy examples:

  • Wall sconces mounted on either side of the mirror (or doubles can be installed above)
  • Vertical bath bar lights
  • Backlist mirrors
  • Carefully positioned pendants

Avoid: A single overhead vanity light, which can create shadows and uneven lighting… especially if it’s directly above.


Accent Lighting

Accent lighting is the cherry on top, and probably my personal favorite to style. Accent lighting adds depth and a designer look. Here are some easy options for integrating accent lights in your bath…

  • LED toe-kick or under-vanity lights (a great option for a nightlight)
  • Table lamp (I love a small lamp on a vanity table or shelf)
  • Gallery lights to accent architectural features, cabinetry, or art

If you go the lamp route, cords can get in the way. Check out this post on how to make any wired lamp cordless.

Fixture Placement Tips

Proper lighting placement makes all the difference in an evenly lit and well designed bath. Here’s how to get it right:

  • Sconces: Mount 60–65 inches from the floor, spaced 36–40 inches apart (depending on mirror width).
  • Recessed exhaust lights: Over the shower… depending on the square footage of your bath, two fixtures may be required to adequately vent your space. I also typically include one of these in the water closet or above the toilet.
  • Vanity lighting: I often flank a mirror with sconces. Specialized bathroom bar lights typically go above the mirror, or on either side of the mirror (no more than 10″ from the edge).
  • Overhead lighting: I like to drop pendants just above the vanity mirror, close to the wall. I also love a statement pendant or chandelier dropped above a bathtub for a focal point vignette. I often center ceiling fixtures in the space, or keep them aligned with a vignette (in front of the tub, centered in the water closet, centered with the doorway, etc).

Choose the Right Bulbs

Never underestimate the impact of your light bulb choice. These are my personal preferences for the bathroom…

  • Color temperature: Aim for 2700K–3000K for a warm, flattering light
  • CRI (Color Rendering Index): Look for a CRI of 90+ to accurately reflect skin tones
  • Lumens: For vanity lighting, 1,500–2,500 lumens is ideal
  • Type: LED bulbs are energy-efficient and last longer… they’re my go-to in most cases

FAQ

How many light sources should a bathroom have?

At minimum, three: recessed exhaust, ambient, and task. Ideally, all four to include accent lighting for balance and depth. It really depends on how large your space is. Small powder rooms are the exception in most cases… you can get away with less.

What’s the best lighting for doing makeup in a bathroom?

Sconces mounted at eye level on either side of the mirror provide the most flattering, even light for makeup application. I also like a pendant dropped just above the mirror. Even better if you have a window or natural light source in your bathroom.

Is daylight or soft white bulbs better for a bathroom?

Soft white (2700K–3000K) is more flattering and creates a warm, inviting tone- especially in bathrooms without windows. Daylight tends to lean more cool and clinical.

Do I really need a dimmer in the bathroom?

It’s personal preference, but it’s definitely a thoughtful amenity that allows for lighting flexibility. Dimmers allow you to shift the mood- bright for morning routines and soft for relaxing baths in the evening.

Can I use pendant lights in the bathroom?

Absolutely! Just make sure they’re damp-rated and installed according to code. Pendants work beautifully above a vanity or tub if you have the ceiling height.

  1. Good morning! You raise some important points on lighting quality in bathrooms. I can hardly wait to properly update our primary- which will definitely require a new lighting plan. My challenge will be the vanity lighting- Jeff’s side poses no issues, but mine sits a little too close to the adjacent wall. You already know I have ideas in my head, but when I figure lighting into the mix, it usually ends up with re-working the layout of the space completely. Is that a sign?? Lol. In all seriousness, expect a text when we get to that point.😂 These are phenomenal tips for me to ponder over; hopefully that will get the wheels turning a different direction. Is it normal to redesign a room 85 times in your head? Asking for a friend. Ha! We had a very warm weekend- but the pool is setup for the season (after having to replace it thanks to a roof leak in our shed) and we are in the last week of school. How do I have a middle schooler?? I hope you had a fantastic weekend as well!

      Hi Lauren! I’m with you on feeling ready to renovate our primary. It’s one big eyesore after another. Ha! Maybe it is a sign to rework the entire floor plan… we’re someplace in the middle, but our lighting plan definitely needs an upgrade. Anyway, I hope this gets your wheels turning. I’m always here to help if you need a second set of eyes! It’s totally normal to redesign a space 85 times in your brain, lol. I’m so excited to hear you’ve got your pool setup for the season. Enjoy it!! Time is flying. I can’t believe you have a middle schooler. They’re growing up fast! Hope you can make sweet summertime memories.

  2. Good morning! Well, talk about a lighting lesson. I can’t imagine a detail you missed! Tbh, every time you write about lighting, I am reminded how little I actually consider it. Can we still be friends? As a homeowner (not a designer), I only think about changing or upgrading existing fixtures. (Or buying lamps, obvi.) Adding or moving hardwired lighting? Creating a lighting plan? Um, no. Sarah, buying light bulbs confounds me. I can’t be deciding on the permanent placement of electrified elements. Lol. Although, if I did want to get crazy and improve our bathroom illumination situation, I couldn’t hope for a better resource! Thanks, as always, for your expertise and encouragement. Cheers to Monday and the first week of June!🌈💜

      Hi Peggy! Lighting is one of my favorite design topics. I actually just thrifted a chandelier for our primary bath renovation! An old Visual Comfort fixture- I’m excited to show you (lucky FBMP find). Of course we can still be friends, ha! I know how much you love lamps. Speaking of… those cordless battery powered options have been so nice. We use them every night. Happy June!!

  3. I love your crisp, clean bathrooms!

    We remodeled our bathrooms and chose the wrong bulbs (bright whtie) and it makes a (terrible) difference. I’m trying to be good and wait for them to burn out, but that could take years more so I’m not sure how long I’ll last. Warmer lights to the rescue, please.

    1. Sarah Gibson says:

      Thank you so much, Dawn! The bulb really does make a huge difference. I think I’d swap them sooner rather than later… maybe you could put them someplace else in your home that you don’t spend as much time in, while you wait for them to burn out? I appreciate your persistence! Hope you’re having a good week.

  4. I love your use of pendant lights in the bathroom, so cleaver! We just bought the fan/light combo you recommended, but of course our one useable ceiling bay has a sistered joist so the cavity is too small. But I’m looking forward to using it on the next project.

      Thanks so much, Julie! I love to hear you bought the fan/light combo. Hopefully you can use it for your next project. It’s really awesome!
