One missed detail in a mirror specification can create a costly problem on site. A cutout in the wrong place, an overlooked edge condition, or a late design change can turn a straightforward mirror package into rework and delays.
So what should be defined before the mirror goes into production? This guide breaks down the key decisions architects, contractors, and designers should get right before sending the specification to Decor Glass Specialties Inc. for fabrication.
Define the Application First
Before specifying dimensions, identify where and how the mirror will be used. A hotel mirror has different requirements from a large mirrored wall in a fitness center. A decorative mirror behind a reception desk may prioritize appearance, while an illuminated mirror requires coordination with electrical and millwork drawings.
Typical commercial applications include:
- Hotels and hospitality interiors
- Fitness centers and health clubs
- Retail stores and showrooms
- Restaurants and entertainment spaces
- Offices and corporate interiors
- Multifamily common areas
- Salons and wellness facilities
- Decorative architectural installations
Defining the application early helps our fabrication team understand the performance, finish, and coordination requirements for custom mirror projects in Atlanta and other locations.
Provide Final Dimensions and Site Conditions
Specify the finished mirror size required for each location and identify surrounding conditions that could affect fabrication or installation.
Include:
- Finished width and height
- Number of pieces and orientation
- Wall or substrate type
- Recesses, millwork, or adjacent trim
- Required clearances
- Panel joints or seams
- Relevant field dimensions
Large installations may need several mirror panels instead of a single piece. If so, show the intended joint locations on the drawings.
Repeated rooms also need careful verification. A hotel may have dozens of similar vanity locations, but field conditions can still vary from room to room. This is especially important when specifying custom mirrors for bathrooms or other multi-unit hospitality projects in Atlanta.
Confirm whether one approved dimension can be repeated throughout the project or whether measurements need to be verified by room, floor, or area.
Specify Mirror Type, Thickness, and Appearance
The mirror should be clearly specified rather than simply labeled “mirror.” Decor Glass Specialties Inc. works with options including black, metallic, tinted, and two-way mirrors, along with decorative treatments, specialty finishes, custom shapes, and dimensions.
Your specification should define:
- Mirror type and thickness
- Color or tint
- Decorative finish
- Shape
- Reflective appearance
- Integrated lighting
- Any artwork or design treatment
Thickness should be considered together with size, mounting method, application, and overall design.
ASTM C1503-24 covers quality requirements for certain silvered flat glass mirrors. It does not establish safety-glazing requirements for specific applications, so applicable building codes and project requirements should be considered separately.
Detail Every Cutout, Opening, and Edge
Mirrors may need to accommodate:
- Electrical outlets and switches
- Wall sconces
- Plumbing fixtures
- Hardware
- Mounting components
- Digital displays
- Other architectural elements
Show the exact size and position of every opening using consistent reference points rather than vague notes such as “cut around outlet.” Also identify which edges will remain exposed, which will be concealed, and what edge treatment is required.
For unusual shapes or decorative fabrication, provide detailed drawings or digital files whenever possible. A clear fabrication drawing gives the manufacturer far more accurate information than a written description alone.
Coordinate Lighting Before Fabrication
Lighting should be coordinated before the mirror is produced.
As acustom mirror manufacturer serving Atlanta and beyond, we create mirrors with integrated lighting and backlit etched areas, so illuminated specifications should clearly define:
- Location of illuminated areas
- Etched or clear sections
- Electrical connections
- Driver or power-supply locations
- Distance from surrounding millwork
- Maintenance access
- Relationship to nearby fixtures
This is particularly important in hospitality, retail, and high-end commercial interiors where the mirror, lighting, and surrounding construction function as one visual element.
Define How the Mirror Will Be Mounted
Project documents should identify the intended mounting method and any backing or framing requirements so the installer, contractor, and manufacturer can coordinate before production.
Avoid specifying a large mirror while leaving the supporting wall unresolved. Uneven or poorly prepared substrates can create installation and appearance problems.
Safety requirements should also be considered at the project level. Mirror quality specifications and safety-glazing requirements are separate considerations, so the design team should confirm what applies to the intended location and use.
Maintain Consistency Across Multi-Unit Projects
Hotels, retail rollouts, fitness chains, and multi-location projects may require dozens or hundreds of mirrors with consistent dimensions, finishes, and appearance. The specification should identify:
- Total quantity and unique sizes
- Repeated units
- Required finishes
- Room or location numbering
- Phasing requirements
- Replacement-piece requirements
For larger commercial orders, consistency matters as much as production capacity. As a custom mirror manufacturer serving Atlanta, we work to maintain the specified dimensions, finishes, and appearance across the full project, including phased and multi-location orders.
Plan Packaging and Delivery Before Production
Commercial mirror specifications should also address how the finished products will be packaged, labeled, and delivered to the jobsite. For large or phased orders, define:
- Delivery location
- Quantity per shipment
- Project phasing
- Floor or room identification
- Site access and receiving requirements
- Packaging and labeling needs
Clear labeling is especially important when an order includes multiple sizes, rooms, or installation phases.
For projects in Atlanta, Chicago, and other locations across the country, we coordinate packaging and shipment requirements early so each mirror package can move from fabrication to the correct jobsite with fewer handling and distribution issues.
What Should a Complete Custom Mirror Specification Include?
Before requesting pricing or releasing a mirror package for fabrication, check that it includes:
- Application: Where and how the mirror will be used
- Dimensions: Finished width, height, and quantity
- Mirror type: Standard, tinted, black, metallic, two-way, or another option
- Thickness: Required thickness for the application
- Shape: Rectangular, curved, geometric, or custom
- Edge details: Treatment for exposed edges
- Cutouts: Locations and dimensions for fixtures and hardware
- Finish: Decorative, painted, etched, or specialty detailing
- Lighting: Integrated or backlit elements
- Mounting: Intended support condition
- Drawings: Elevations, shop drawings, or digital artwork
- Identification: Room, elevation, or location numbers
- Delivery: Packaging, phasing, and jobsite requirements
The more complete the specification, the easier it is for a commercial glass and mirror manufacturer to review the project accurately before fabrication begins.
Common Specification Mistakes to Avoid
Using design dimensions without field verification. Confirm when field measurements are required and who is responsible for providing them.
Leaving openings until later. Outlets, lighting, hardware, and other cutouts should be coordinated before fabrication.
Assuming repeated locations are identical. Allow for construction tolerances and variations in surrounding finishes or wall conditions.
Leaving edge conditions unspecified. Identify which edges will remain exposed and what finish is required.
Adding lighting too late. Integrated and backlit features should be coordinated before the mirror design is finalized.
Ignoring delivery logistics. Even a correctly fabricated mirror can create problems if the packaging, labeling, or delivery sequence does not suit the jobsite.

Frequently Asked Questions
What information do I need to request a custom mirror quote?
Provide the finished dimensions, quantity, mirror type, thickness, edge details, cutouts, finishes, and delivery location. Drawings or elevations are especially helpful for commercial projects with custom shapes, lighting, or repeated configurations.
How do I measure for a custom mirror?
Measure the finished opening or installation area and note any trim, millwork, outlets, fixtures, or clearances that could affect the final size. For larger commercial projects, field verification is recommended before fabrication begins.
What thickness mirror do I need for a gym or commercial space?
The right thickness depends on the mirror size, mounting method, wall condition, and intended use. Large gym walls and other commercial installations should be reviewed with the fabricator so the mirror thickness and panel layout suit the project.
Can a custom mirror be cut around outlets and light fixtures?
Yes. Cutouts can be planned for outlets, switches, sconces, and other fixtures, but their exact size and position should be finalized before fabrication. Clear drawings or verified measurements help prevent alignment problems on site.
Can custom mirrors be made for hotels or bulk commercial projects?
Yes. We can produce repeated mirror configurations for hotels, fitness centers, retail rollouts, and other multi-unit projects. For custom mirrors for bathrooms in Atlanta, provide room quantities, size variations, finish requirements, and any phased delivery needs early.
Do custom mirror manufacturers ship nationwide?
Yes. Commercial mirror orders can be packaged, labeled, and coordinated for delivery to projects in different parts of the country. As a custom mirror manufacturer serving Atlanta and other locations, we can plan shipments around project phases, room numbers, and jobsite requirements.
