30L/35L Stainless Steel Laundry Sink Cabinet — Watermark Certified for Bathroom and Laundry

Compact Laundry Sink Cabinet for Space-Constrained Installations

Stamped Single Bowl Construction

Where laundry square footage is limited — in apartment closets, under-stair utility nooks, or bathroom-laundry combinations — a compact laundry sink cabinet with a single deep basin serves daily washing tasks without monopolizing floor area. The stamped 304 stainless steel bowl measures 557 × 453 × 250 mm, holding 30 or 35 liters depending on the model selected. Stamping produces a seamless bowl with no welded seams in the basin floor or walls, which eliminates crevices where residue and moisture can accumulate over years of use. The brushed finish runs consistent across the stamped surface, concealing water spots and minor abrasion from daily loading and unloading of laundry items.

Four Model Variants for Different Layouts

The CLA145, CLA146, CLA142, and CLA143 models cover four orientation and dimension combinations, giving specifiers flexibility to match the sink to the available wall space and plumbing rough-in position. CLA142 measures 560 × 455 mm in footprint with the basin oriented along the wider dimension, while CLA143 reverses that orientation to 455 × 560 mm — useful when the cabinet sits in a narrower alcove or beside existing appliances. This range means a single product family can serve multiple unit types within a residential development, simplifying procurement and standardizing replacement parts across a property portfolio.

Watermark Certification and Plumbing Compliance

Australian and New Zealand Standards

Watermark certification confirms that this laundry sink cabinet meets the plumbing code requirements enforced in Australia and New Zealand, where uncertified fixtures cannot be legally installed in residential or commercial buildings connected to mains water supply. For developers and builders working in these markets, specifying Watermark-certified fixtures is not optional — it is a regulatory prerequisite for building sign-off and occupancy approval. The certification covers the sink’s drainage performance, material safety in contact with potable water supply lines, and structural integrity under normal service conditions.

Global Certification Portfolio

Beyond Watermark, Xinhe holds cUPC certification for North American plumbing compliance, CE marking for European market access, and NSF/ANSI 61 certification for drinking water system component health effects. ISO 9001 and SGS certifications cover manufacturing quality management. This portfolio allows the same product family to be specified across international project portfolios — a developer building residential complexes in Australia, the Middle East, and Southeast Asia can standardize on one sink model and meet regional compliance requirements without sourcing separate fixtures for each market.

Where This Cabinet Belongs

Residential Utility and Apartment Laundry

Apartment developers and residential builders specify this cabinet in individual unit laundry closets where space allocation typically ranges from 1.5 to 2.5 square meters. The 560 mm width fits alongside standard washing machines in stacked or side-by-side configurations, and the 870–900 mm height range matches standard counter levels for visual continuity in open-plan laundry zones. The base cabinet provides enclosed storage for detergent bottles, stain treatment supplies, and cleaning cloths — keeping the visible laundry area uncluttered between uses. In bathroom-laundry combinations common in Australian and Southeast Asian residential design, the cabinet’s moisture-resistant construction handles the elevated humidity levels typical of shared bathroom-laundry spaces.

Mudrooms and Small Commercial Spaces

Mudrooms in family homes use this cabinet for rinsing muddy footwear, washing outdoor gear, and handling messy tasks that homeowners prefer not to do in the kitchen sink. The deep 250 mm bowl accommodates boots and small buckets, and the stainless surface resists staining from soil, clay, and organic matter. Small commercial operations — daycare centers with craft and meal cleanup needs, small cleaning services rinsing mops and equipment — also fall within this cabinet’s service range, where the footprint is too small for a commercial-grade compartment sink but the tasks exceed what a standard bathroom basin can handle.

Cabinet Construction and Moisture Resistance

Base Cabinet Engineering

The cabinet base is engineered for laundry room humidity, with materials selected to resist moisture penetration from both ambient air and incidental water contact. Adjustable legs elevate the cabinet base off the floor, preventing wicking from wet flooring — a common failure point in utility rooms where floor drainage or minor overflows expose cabinet bases to standing water. The legs also accommodate floor irregularities up to 30 mm, which is relevant in older building retrofits where subfloor levels vary. Pre-cut sink openings and pre-installed faucet holes align with standard plumbing configurations, reducing on-site fabrication time during installation.

Surface Finish and Durability

The brushed stainless finish serves a functional purpose beyond appearance: the fine linear texture diffuses light reflections that would otherwise highlight water spots, fingerprints, and minor scratches accumulated through daily use. This makes the cabinet maintain a cleaner visual appearance between scheduled cleaning cycles — relevant in shared residential laundry rooms where multiple households use the same facility. The 304 grade stainless steel resists rust and staining from common laundry chemicals including detergents, fabric softeners, and oxygen-based stain removers.

Sizing and Configuration Guide

Standard Dimensions

Custom Size Options

Beyond the four standard models, custom basin dimensions, cabinet heights, and color finishes are available through OEM/ODM specification. Developers standardizing on a particular cabinet height to match adjacent laundry appliances can request a fixed height rather than the adjustable range. Custom color finishes — including black, white, gun metal, gold, brass, and rose gold — allow the cabinet to match interior design schemes in visible laundry areas within open-plan living spaces.

Procurement and Project Supply

MOQ and Lead Times

Minimum order quantity for this model is 100 units, suited to residential development projects, hotel group procurement, and distributor stocking. Lead times depend on order volume, customization scope, and material availability, with standard production running through Xinhe’s Guangdong facility. For project buyers managing construction schedules, the sales team provides production timelines and can consolidate shipments across product categories — laundry sinks, kitchen sinks, and public sanitary ware — to reduce logistics complexity on multi-unit builds.

OEM Branding and Packaging

OEM services cover private-label branding on cabinet panels, custom packaging for direct-to-site delivery, and accessory bundling (strainers, drain pipes, faucets) matched to the specified basin configuration. Distributors entering the Australian and New Zealand markets can specify Watermark-certified units with their own brand identity, packaging, and documentation. The 20-year track record serving North American, European, and Australian buyers informs the team’s understanding of regional documentation requirements, labeling standards, and compliance paperwork.
