The Hotel Bathroom Mirror: What to Specify Before BDNY 2026

By Beverly Gene, Design Consultant, Claris Company. Every product detail in this guide is checked against the specifications of the mirrors Claris builds.

Published October 2026.

To specify a hotel bathroom mirror, set CRI 90+ light at one colour temperature per room type, anti-fog in every bathroom with a shower, controls a guest understands without instructions, an accessible mounting height, and one size per room type, repeated across the keys.

Every guest uses it, every morning, in a room they do not know. BDNY, the boutique hotel design fair, comes to the Javits Center on November 8 and 9. Here is the detail behind each point, before you walk it.

Hotel mirror specification checklist

BDNY 2026 at a glance

BDNY is organized by Emerald. The 2025 edition drew more than 11,000 qualified attendees from more than 50 countries, with about 750 exhibitors.

How should a hotel bathroom mirror be lit?

Light the face, at CRI 90 or higher, with one colour temperature per room type. A hotel bathroom is lit for a stranger. They will shave, do their makeup or check a shirt under that light, often before sunrise.

The research agrees. In the NKBA's 2026 bath trends report, 91% of the experts surveyed rank lighting quality as a top priority, and 92% say task lighting belongs in every primary bath. Integrated lighting in mirrors is listed as an emerging trend.

Three things to ask:

• Colour rendering. Claris mirrors carry CRI 90+ LEDs. Skin stays warm. Whites stay white.
• Colour temperature. 3000K is warm, 4000K is neutral, 5000K is cool. Read 3000K or 4000K for the bathroom for the full comparison.
• Where the light goes. Front-lit puts light on the face. Backlit washes the wall. See backlit vs front-lit mirrors, and our designer's guide to bathroom mirror lighting.

The glass matters too. Claris builds on Diamond ClearVision, an extra-low-iron Belgian glass. Standard mirror glass is faintly green. In a white marble bathroom, the guest sees the difference.

What anti-fog should a hotel mirror have?

A heated film behind the glass, specified at the start. A fogged mirror is the first complaint after a hot shower. On Claris anti-fog models, a heated film sits behind the mirror and clears the glass where the guest looks.

On a shaped or custom mirror, the film is a sealed element: it cannot be cut, and nothing else mounts on it. The factory lays out the rest of the mirror around it. More in how anti-fog mirrors work, or browse anti-fog mirrors.

Which mirror controls do hotel guests understand?

A wall switch or a wave sensor: neither needs instructions. Every control is a question the guest has to answer at night.

• A wall switch. The simplest. Hardwired to the room switch, the mirror has no buttons. Light and anti-fog come on together.
• A wave sensor. A hand passes in front of it. Claris ships the wave motion sensor on its sensor builds.
• Dimming from the wall. Possible, and decided at the factory. A mirror built for a wall dimmer has no internal driver; an external dimmable driver sits in the wall or the vanity. Choose it with the order.

Plan the rough-in with the electrician before the walls close: the supply position behind each mirror, a separate connection behind the glass for anti-fog, and, on a wall-dimmed build, where the driver lives. A mock-up room is the place to prove all three before the order runs across the keys.

Mounting and service access

Ask two questions at specification. How is the mirror secured to the wall? And how does maintenance reach the connections later? Plan solid blocking in the wall behind every mirror before drywall, and keep any external driver where an engineer can reach it, in the vanity or a serviceable box, without lifting the glass off a tiled wall.

How high should a hotel bathroom mirror hang in accessible rooms?

In accessible rooms, the 2010 ADA Standards set the height. Over a lavatory or countertop, the bottom edge of the reflecting surface sits 40 inches maximum above the finished floor. A mirror that is not over a lavatory or counter goes lower: 35 inches maximum.

A tall mirror solves both at once: the bottom edge comes down to the counter line, and the top still reaches eye level for a standing guest. Our architectural mirror sizing guide has the height formula.

How should hotel mirrors be sized across room types?

One size per room type, built once and repeated across the keys. Hotels are built in key counts. A mirror that fits one room has to fit two hundred, the same way, from the same build.

Claris builds to the size the project calls for. Shape, lighting, controls and anti-fog are configured per room type and repeated across the keys. Lead times are confirmed in every quote. Start with how to specify a custom mirror. For double-vanity suites, pieces such as MERCURE carry two round apertures, one over each basin.

Care across the keys

Housekeeping cleans every mirror every day. A microfiber cloth and warm water do the job: liquid on the cloth, never on the glass, and no ammonia-heavy, acidic or abrasive cleaners near the edges, where the silvering and the electronics live. Read how to clean an LED mirror without damaging it and pass it to the operations team at handover.

Mirrors for the lobby washroom

The lobby washroom and the restaurant bathroom are where a design hotel shows what it is. That is the room for a piece. At OCHE King West in Toronto, the Gemini and Butterfly mirrors did that job: read the OCHE King West washroom case study.

Frequently asked questions

What should a hotel bathroom mirror include?

CRI 90+ lighting at one colour temperature per room type, anti-fog in any bathroom with a shower, controls a guest understands without instructions, an accessible mounting height, and a size built to the room type and repeated across the keys.

What colour temperature suits a hotel bathroom mirror?

Most guest bathrooms sit at 3000K or 4000K. 3000K is warmer and calmer; 4000K is closer to daylight and better for grooming. Match it to the room's other lighting.

How high should a mirror be in an accessible hotel bathroom?

Over a lavatory or countertop, the bottom edge of the reflecting surface sits 40 inches maximum above the finished floor, under the 2010 ADA Standards (603.3). Elsewhere, 35 inches maximum.

Should a hotel mirror have anti-fog?

In any bathroom with a shower, yes. A heated film behind the glass keeps the face area clear.

Can a hotel mirror dim from a wall dimmer?

Yes, when it is built for it at the factory, with an external dimmable driver. A standard hardwired mirror does not dim from the wall.

When is BDNY 2026?

November 8 and 9, 2026, at the Javits Center in New York, 10 am to 5 pm both days.
