Quick answer: This case study covers a three-piece custom shower-niche sample set: two units at approximately 338 × 827 × 100 mm overall and one unit at approximately 294 × 827 × 100 mm. All three were produced in a coordinated matte black finish with three internal compartments.

Project snapshot

  • Quantity: three custom sample units
  • Configuration: three internal compartments per niche
  • Overall sizes shown on the drawing: two pieces at 338 × 827 × 100 mm and one piece at 294 × 827 × 100 mm
  • Finish: matte black
  • Use case: size-matched recessed storage modules for a coordinated bathroom layout

Why three sizes were tested together

Ordering two units in one width and a third in a narrower width is a useful way to validate a modular design. The buyer can check that the shelf heights, compartment proportions, face frames, and finish remain consistent even when the overall width changes.

Manufacturing and finish inspection

Production photos show the units hanging during finishing and inspection. A repeatable matte black appearance depends on surface preparation, controlled coating, careful handling between stages, and a final review under consistent light. The three-unit sample format makes these differences easier to spot before a larger batch.

Packaging and handoff

The finished set was packed in protective cartons for local transport and onward delivery. For multi-piece samples, labels should identify the width or drawing reference so the installation team can place each unit correctly.

Buyer takeaway

This case is a good model for developers, hotel projects, bathroom dealers, and custom-home contractors who need a family of niches rather than one standard size. Share one dimensioned drawing per variation, specify the finish once, and approve the complete sample set before releasing a larger order.

FAQ

Can the compartment heights be changed?

Yes. The drawing should show each internal opening and the intended shelf or divider position before fabrication.

Can one design include both wide and narrow units?

Yes. The case demonstrates how the same three-compartment concept can be adapted to different overall widths.

How do I request a similar set?

Send the overall sizes, internal layout, material, finish, quantity, and installation conditions through the APEX quotation page.
