Key takeaways
- Build a room-based finish schedule with codes, product references and approval status
- Decide on physical samples, not screens, for colour, texture and sheen
- Review samples under the lighting of the destination space
- Treat natural stone variation as a separate approval, not a colour name
- Confirm technical suitability for the intended environment and cleaning method
- Document any substitution and its effect on related items
The aim is a deliberate relationship between surfaces. Tiles, stone, painted cabinetry and metal hardware may complement one another without being identical.
1. Start with a room-based finish schedule
Give each finish a code and list where it will be used. Include the material, supplier reference, surface treatment and sample approval status.
| Field | Example of information to record |
|---|---|
| Location | Kitchen island, guest bathroom or entrance floor |
| Product reference | Manufacturer or supplier code |
| Finish description | Colour, texture, sheen and surface treatment |
| Related items | Worktop, cabinet front, handle or adjacent flooring |
| Approval record | Sample reference, revision and approval date |
| Open decision | Alternative under review or specification still required |
Use descriptive names for convenience, but retain the actual product codes.
NKBA offers kitchen and bath planning guidance; review material choices alongside layout and use requirements. [1]
2. Review physical samples together
Screens and photographs are useful for shortlisting. They can change the appearance of colour, texture and sheen, so use physical samples for decisions where those differences matter.
Compare the major surfaces alongside the smaller details: grout, trims, handles, frames and sealants where relevant. Review them under lighting representative of the intended space. A choice made in one showroom light may look different at the destination.
NCS explains metamerism: surfaces matching under one illumination can differ under another. This supports reviewing samples under relevant lighting. [2]
3. Treat natural variation separately
Natural stone and other variable materials require a discussion about the range of appearance. One small sample may not describe the full slab or batch.
Where pattern or veining matters, ask what larger images or layout approvals are available before cutting. Record whether the approval concerns a general material selection or particular pieces.
The Natural Stone Institute links stone care to its classification and composition; obtain material-specific maintenance information with the selection. [3]
4. Connect appearance with technical suitability
A coordinated palette still needs products suitable for their application. Check the actual product information for the intended environment, cleaning method and installation system. Let the designer or relevant specialist resolve technical requirements that cannot be established from appearance alone.
WBDG identifies specifications and submittals among commissioning records; keep technical product information alongside appearance approvals. [4]
VIGOHOME’s product range includes finishes, fitted products and furnishings. Its service process includes sample approval before production. Ask how the approved selections will be referenced across your quotation and order.
5. Approve substitutions explicitly
If a selected finish becomes unavailable, assess the replacement beside the other approved materials. A similar description does not guarantee the same appearance or performance.
Document the substitute, its effect on related items and the person authorizing the change. Update the schedule so purchasing and inspection teams do not work from different versions.
CIPS begins procurement with defined specifications; keep the purchasing requirement current when a substitute is approved. [5]

Frequently asked questions
Can I approve finishes from photographs?
Use photographs for shortlisting, but decide colour, texture and sheen from physical samples under lighting representative of the destination space.
Why do two matching samples look different on site?
Metamerism: surfaces that match under one light source can differ under another. Review the scheme under the lighting expected in the room.
How should natural stone variation be approved?
Treat it as a separate decision. A small sample may not represent the slab or batch; ask for larger images or a layout approval before cutting.
What should a finish schedule record?
Location, product reference, finish description, related items, approval record and any open decision, so purchasing and inspection teams work from one version.
Next: plan how the approved package will be labeled by room.
