Vanity mirrors in multifamily residential units are installed after cabinet installation is complete but before the plumbing sub trims out the bath faucet and before lighting fixtures above the vanity are connected. They are a coordination-dependent installation that appears simple but generates a consistent category of problems when the size, mounting location, or installation sequence is not confirmed at pre-construction.

On Washington multifamily projects, particularly in the Seattle and Bellevue Class A market where design standards are high and the superintendent’s first walk is a detailed review, a vanity mirror that is the wrong size, mounted at the wrong height, or installed before the lighting fixture above it has been located precisely is a punch list item that costs time and money to correct.

Sizing coordination with cabinets and lighting fixtures

Vanity mirror sizing must be confirmed against two fixed elements: the cabinet width below the mirror and the lighting fixture above the mirror. The mirror must clear the cabinet doors and drawers when they are opened. The mirror must not block the lighting fixture above it, and the top of the mirror should align with or fall below the bottom of the light fixture bar.

These are not always the same dimension. A 30-inch-wide single-sink vanity cabinet may be paired with a 24-inch-wide mirror to allow clearance for the cabinet doors, a 30-inch mirror that matches the cabinet width exactly, or a 36-inch mirror that extends beyond the cabinet width to create a larger visual. The project’s design drawings should specify the mirror dimensions. If the drawings do not specify mirror dimensions precisely, the Division 8 sub should request a clarification before ordering.

On projects where the mirror dimensions are not specified and the Division 8 sub orders a standard size without confirming against the cabinet and lighting layout, the result is a mirror that does not look intentional. On Class A projects in Seattle and Bellevue where the developer’s marketing materials feature the bath as a design element, a mirror that looks like a default selection is a deficiency.

ADA mirror requirements in Washington common area restrooms

Common area restrooms in Washington multifamily projects, including leasing office restrooms, fitness center restrooms, and accessible unit bathrooms, must include mirrors that comply with ADA Standards for Accessible Design. The ADA requires that mirrors over lavatories in accessible restrooms have the bottom of the reflective surface no higher than 40 inches above the finished floor.

In practice, this means that a standard mirror mounted at a standard residential height may not comply in an accessible restroom. Confirm the mirror mounting height in every common area restroom against the 40-inch ADA requirement before installation. On projects where the accessible restroom mirror is mounted at a non-compliant height, the correction requires removing the mirror, patching and repainting the mounting holes, and reinstalling at the correct height, which is a cost that no party wants to absorb.

Frameless versus framed vanity mirrors on Washington projects

Frameless mirrors are specified on most Class A and Class B multifamily projects in Washington’s metro markets. Frameless mirrors are cut to the specified size from large mirror stock and polished at the edges. They are mounted directly to the wall with clips or adhesive mounts. The visual result is clean and contemporary.

Frameless mirrors require that the wall behind the mirror be flat and smooth, because the mirror will telegraph any irregularities in the wall surface. If the drywall behind the mirror location has blisters, ridges, or joint compound build-up, those irregularities will be visible in the reflection. Confirm that the drywall and paint in the mirror mounting location are finished to a flat, uniform surface before the mirror is installed.

Framed mirrors are specified on projects where the design calls for a specific frame style or material. Framed mirrors are more forgiving of minor wall surface irregularities because the frame creates a separation between the mirror and the wall. They are more common on projects with a traditional design aesthetic.

Installation sequence for vanity mirrors

Vanity mirrors install after cabinet installation is complete and after prime coat paint is applied to the wall behind the mirror location. Installing mirrors before prime coat means the paint crew will need to mask the mirror during painting, and overspray at the mirror edges is a common result.

Mirrors should be installed before the plumbing sub returns to trim out the bath faucet, so that the plumbing sub does not need to work around the mirror installation. The sequence on a typical Washington multifamily floor: cabinets set, prime coat paint, mirrors installed, finish paint, countertops set, plumbing trim-out, flooring, toilet accessories and wire shelving, window treatments, punch walk.

Common area lobby and fitness mirrors

Common area mirrors in lobbies, fitness centers, and yoga rooms are typically larger than residential vanity mirrors and require specific wall blocking to support the weight of the glass. A large lobby mirror or a full-height fitness room mirror requires structural backing in the wall at the mounting locations. Confirm blocking requirements with the Division 8 sub before the framing crew advances on the relevant walls.

Fitness room mirrors that run floor to ceiling or wall to wall are installed as continuous mirror panels with thin joint lines between panels. The panel joint pattern should be confirmed against the room dimensions before ordering to avoid a layout where the last panel at one end of the room is a narrow strip that looks like a cutting mistake.
