First-article inspection is the point at which a buyer asks: does the first completed unit represent the approved design closely enough to release the production process? For a bathroom vanity, this review can expose dimensional, construction, finish, hardware, basin and packaging problems before they affect the full order.
The first article is not a random finished unit selected at the end. It should be produced using the intended drawings, materials, components, tools and processes. The inspection result becomes an approval gate, with any limitations recorded explicitly.
Define the purpose and scope
State whether the first article covers one model, one size, one finish or a product platform. Do not assume that approval of a small single-drawer vanity covers a wider double-basin unit, or that one finish validates another process. Identify which variants share construction and which contain new risks requiring separate review.
Agree on the decision outcomes before inspection: release, conditional release for contained operations, or hold and correct. A schedule deadline should not turn an unresolved first article into silent approval.
Prepare the controlled inspection pack
The inspector needs the purchase order, final shop drawing, component and finish schedules, approved samples, critical-to-quality list, inspection method and known deviation log. Each file should carry a revision. Remove obsolete documents from the working pack.
Identify the unit with the project, model, finish, date and production reference. Record whether any material or component differs from the intended production configuration. If the unit uses a temporary substitute, the affected characteristic cannot be fully approved.
Start with identity and configuration
Confirm overall model, size, handedness, finish, top, basin, hardware and included accessories. Compare labels and model markings with the controlled schedule. Configuration errors often look like quality issues but originate in order data, so record the exact mismatch.
The bathroom vanity category can help identify a product family, while first-article approval must refer to the exact ordered variant.
Measure the assembly and interfaces
Measure overall width, height and depth, then critical internal and interface dimensions. These may include drawer clearances, plumbing zones, top overhangs, basin and tap centres, wall contact areas, mounting points and rear service clearance. State the measuring tool, location and approved tolerance.
Check squareness, level relationships, consistent reveals and alignment. Place the unit in a safe, representative position. Wall-mounted products require project-specific structural and installation review by qualified parties; the first-article inspection can verify declared cabinet fixing points but cannot approve the site wall.
Verify materials and construction
Compare declared substrates, thicknesses, surface materials, backs, drawer parts, shelves, reinforcements and joinery with the component schedule. Inspect visible and concealed edges, cut-outs, drilled areas and joints for damage, incomplete finishing or inconsistencies.
Where identification cannot be confirmed visually, use the agreed traceability or supplier records rather than guessing. A colour match does not prove that two materials have the same construction.
Review finish under controlled conditions
Compare colour, sheen, texture, grain direction and acceptable variation with the approved physical reference. Use consistent viewing distance and lighting. Examine fronts together as an assembly because differences can be less visible on isolated panels.
Record scratches, chips, dents, contamination, patchiness, edge exposure and touch-up. Photographs should include the model identifier and a location reference. Camera images support the report but should not replace the physical appearance standard where colour is critical.
Operate hardware and storage
Open every door and drawer. Check rubbing, clearance, alignment, pull access, soft-close behavior where specified, stops, shelf fit and access around plumbing. Confirm that handles and fittings match the schedule and are securely installed.
A short functional check does not establish long-term durability. Its purpose is to detect assembly and operation faults present in the first article. Any required performance or cycle test should use a separately agreed method and acceptance criterion.
Inspect the top, basin and tap interfaces
Check fabricated top dimensions, edge profile, openings, backsplash, seams, support and contact with the cabinet. Review the actual offered surface against its approved reference and variation range. Confirm basin position, support, overflow or waste details where relevant, and clearances to drawers and structure.
If the tap is included in the assembly review, verify hole position, reach relationship and operating clearance. Water, drainage, load or seal tests should be performed only under the defined method and safe setup. Browse basin options and tapware options when building the interface schedule.
Use a characteristic-level report
| Characteristic | Requirement | Observed result | Disposition |
|---|---|---|---|
| Overall width | Drawing value and tolerance | Measured value and tool | Pass / fail |
| Front alignment | Approved visual or measurable limit | Location and observation | Pass / correct |
| Finish | Reference and variation range | Viewing result and photos | Accept / resubmit |
| Drawer operation | Specified movement and clearance | Operation performed | Pass / adjust |
| Basin interface | Coordinated drawing | Measured position and clearance | Pass / revise |
“Looks good” is not a repeatable inspection result. The report should connect each important characteristic to its requirement, evidence and decision.
Classify and close nonconformities
Describe each issue with model, location, requirement, observed condition and photograph. Classify severity using the project’s agreed definitions. Assign cause investigation and corrective action without jumping from symptom to conclusion.
Correction of one unit is not enough when the production process could repeat the issue. Ask what control will prevent recurrence, where it will be checked and which record will confirm implementation. Reinspect the characteristic on the corrected first article or a replacement unit as agreed.
Freeze the accepted reference
After approval, link the first article or retained reference to the drawing, finish sample, component schedule and report. Mark conditional points clearly. If the physical unit will be used as a golden sample, protect and identify it so it cannot be sold, altered or confused with a prototype.
Physical samples can age or vary, so they complement rather than replace dimensions, material descriptions and measurable limits.
Connect approval to process control
Translate first-article findings into in-process checks. A difficult drawer alignment may need a fixture or early measurement; a finish variation may require batch review; a top opening may need template control. State the frequency, responsible role and reaction if the result moves outside the limit.
Release only the processes supported by the accepted evidence. If the top is still pending, cabinet work may be contained while top fabrication remains on hold, provided the interface risk is controlled and authorized.
Do not overlook packaging
Once the product is accepted, review its final packed configuration. The package should protect finished surfaces, corners, moving parts, loose accessories and any glass or top. Validate it using the agreed route or test method, then reinspect the product.
Build the first-article gate into the enquiry
Include first-article expectations before ordering so sample cost, timing and production holds are visible. Review relevant models through the ArcQuay product centre, then send the drawing, finish, quantity, destination and approval plan. A first-article gate is most effective when both buyer and supplier know exactly what it must decide.
