What to Look for When Choosing Recessed Lighting for Bathrooms

Bathrooms have rules that other rooms don't. Get the wet location rating wrong and you've got a code violation. Get the color temperature wrong and the room just never works right.
Bathrooms are spaces where recessed lighting decisions can have added major consequences. In a living room, picking the wrong fixture means the room might feel a little off. In a bathroom, it can mean a code violation, a failed inspection, or a fixture that corrodes inside six months. The stakes are different.
Most of it comes down to a few things that don't get enough attention at the point of purchase.
Location inside the bathroom determines the fixture you need
Not all of a bathroom is the same zone, and the electrical code treats them differently. Directly over a shower or tub — within about eight feet vertically — requires a wet location rated fixture. The area just outside that, within a few feet of the tub rim, needs damp location at minimum. The rest of the bathroom can use most any standard fixture.
The labels to look for on the spec sheet are "wet location UL listed" and "damp location UL listed." They're not the same thing and they're not interchangeable. A damp-rated fixture directly over a shower is a code violation waiting to be flagged.
This sounds obvious, but it's often overlooked. People spec a fixture they like, check that it's an LED, and don't look further. The wet/damp rating will be shown on the product package and description — it just requires notice.

Color temperature is a more loaded decision here than in other rooms
Bathrooms get used for two different things that want different light. Getting ready in the morning — applying makeup, shaving, anything where you need to see accurately — benefits from a cleaner, more neutral light, somewhere around 3000K to 3500K. The warm amber that works beautifully in a living room at 2700K can cast a yellow tone that makes it hard to judge color accurately in a mirror.
At the same time, a bathroom that runs too cool feels clinical and uninviting, especially if it doubles as somewhere you want to decompress at the end of the day.
The practical answer is 3000K for most bathrooms. It's neutral enough to be functional at a vanity and warm enough that the room doesn't feel like a hospital corridor. Bathrooms can also be very appropriate places to use "Sunset Dim" or "Warm Dim" features... see our post describing that feature here...

CRI matters more here than in most other rooms
If there's one room in the house where high CRI earns its cost, it's the bathroom. CRI — color rendering index — determines how accurately the light shows the colors of what it's illuminating. In a bedroom, low CRI mostly means the room looks a little flat. In a bathroom, it means your skin tone in the mirror looks off, and you might walk out dressed in colors that don't actually go together.
90+ CRI is the floor for a bathroom. 95+ is better. It's usually listed on the spec sheet alongside the color temperature, and it's worth checking before assuming.

Airtight housings keep moisture from becoming a long-term problem
Bathrooms generate steam. Steam finds its way into ceiling cavities through any gap it can, and recessed light housings are a common entry point. Over time that moisture damages insulation, creates mold conditions, and can corrode the fixture from the inside.
Airtight IC-rated housings aren't just for energy efficiency — in a bathroom they're a moisture management decision. The airtight designation means the housing is sealed well enough to resist that infiltration. It won't matter which wet-rated trim you chose if moisture is getting in through the back of the housing.

Bathrooms aren't where you want to discover you made the wrong call. The wet location rating, the color temperature, the CRI, the housing seal — none of it is complicated to check. It just requires checking it before the order goes in rather than after the fixtures are already in the ceiling.
