How to Verify a Lighted Shower Niche Sample Before Mass Production

To make sure mass-produced lighted shower niches match the approved sample, establish a documented product reference and check production units against its agreed dimensions, finish, lighting performance, electrical requirements, and packaging. The product records provided here describe a swivel heated towel rack rather than an illuminated shower niche, so they cannot confirm niche-specific specifications or certification.

Set the Reference Before Production

Start by identifying the exact niche model and approving a physical sample alongside its drawings and acceptance criteria. The available records contain no lighted-niche dimensions, lighting details, wiring requirements, finish standards, or permissible production tolerances. The heated towel rack data should not be used as a substitute.

Once criteria are agreed, inspect the reference sample and production units using consistent methods. Record each result, and hold any unit with an unexplained difference until it has been reviewed against the approved documents. For lighting and electrical checks, define the test method and pass conditions with the supplier in advance; those requirements are not included in the supplied niche information.

What the Available Records Confirm

The supplied product listing is for an ODO-R2B swivel electric heated towel rack. It specifies 304 stainless steel, a product size of 620 × 218 × 360 mm (customized), 44 W power, IP44 waterproof grade, and CE and design patent certificates. These details apply to the towel rack only, not to a lighted shower niche.

The knowledge base names two shower-niche certificates: “Shower niche CE EMC Certificate-AiTSZ-250428030C-C01” and “Shower niche CE - WUX202404021012RC.” However, the records do not connect either certificate to a particular illuminated niche model or configuration. Verify certificate scope against the exact product being ordered.

ODO describes residential bathrooms and hotels as application scenarios. Its project references include a Warsaw hotel renovation with floor drains and wall-mounted heated towel rails, and a Milan villa project with tile-insert drains, wall niches, and bathroom accessories. These examples do not provide a sample-to-production inspection procedure for lighted niches.

Frequently Asked Questions

Do these records specify an illuminated shower niche?

No. The product listing covers a swivel electric heated towel rack and does not state niche dimensions, lighting requirements, or production tolerances.

Do the listed certificates prove compliance for a lighted niche?

Not on their own. Although two shower-niche certificates are mentioned, the available information does not identify the covered lighted-niche model. Check each certificate against the product and configuration you plan to purchase.

What information should be agreed before mass production?

Document the exact model, approved physical sample, drawings, inspection points, and acceptance limits. Since the supplied records do not include niche-specific criteria, establish them with the supplier before production begins.

Recommendation

Use a signed-off, documented niche sample as the production benchmark, supported by product-specific drawings and measurable acceptance criteria. The available information notes that the company uses 14 QC processes and offers OEM and ODM services, but it does not verify lighted-niche specifications or describe a sample-matching procedure.
