Discover our precision-engineered linear shower drains and complementary high-end vanity systems manufactured specifically for commercial hotels, multi-residential apartments, and luxury residential projects across New Zealand.
An in-depth engineering analysis on hydraulic efficiency, sub-floor membrane integration, metallurgical durability, and regulatory compliance tailored specifically for New Zealand architects, hydraulic consultants, master plumbers, and commercial procurement managers.
New Zealand’s architectural landscape has undergone a major paradigm shift toward seamless, barrier-free living environments. Level-entry wet rooms and curbless showers are no longer restricted to specialized accessible design under NZBC G5 (Accessibility); they have become the benchmark standard for high-end residential builds in Auckland, Wellington, Christchurch, and commercial hospitality projects nationwide. Achieving a zero-threshold shower transition without compromising structural integrity requires linear drainage channels engineered for extreme water evacuation rates, precision flange perimeter welding, and seamless bonding with liquid waterproofing membranes.
Exporting sanitaryware and drainage channels to New Zealand demands rigorous adherence to regional plumbing and building codes. Non-compliant drainage systems expose builders and developers to costly council sign-off delays, failed Code Compliance Certificates (CCC), and devastating moisture ingress claims under the Building Act 2004.

| BRANZ Appraisal Alignment | Independent technical verification validating product suitability when integrated with proprietary NZ wet room waterproofing systems. | CAD drawings, BIM models, and technical installation manuals designed for straightforward council consent submittals across all NZ Territorial Authorities. |
New Zealand building typologies require distinct physical drain geometry dependent on the ground floor and upper-floor substrate construction:
Installed directly onto fiber-cement sheet underlayment over structural floor joists. Requires shallow profile linear channels (24mm trough depth) with horizontal outlet connections. Flange detail rests flat on sheet floor, enabling liquid membrane to bridge seamlessly from floor into drain channel without step-ups.
Cast directly into the concrete floor or set into screed recesses. Features height-adjustable levelling legs (range 40mm–90mm) and 360-degree rotating siphon traps for rapid alignment with pre-cast plumbing pipe drops. Vertical DN50/DN75 waste drops ensure maximum gravity-assisted velocity.
Engineered with a 90-degree vertical rear flange wall uplift. Positioned directly against timber wall framing before plasterboard/tiling installation. Eliminates double-slope floor grading, allowing a single single-plane fall towards the rear shower wall for large-format porcelain tiles.
As an OEM/ODM manufacturing partner for major sanitaryware brands and commercial importers across Australasia, our production plant utilizes state-of-the-art fiber laser cutting, CNC hydraulic press braking, and robotic TIG welding lines.
While standard AISI 304 stainless steel performs adequately in low-humidity inland environments, New Zealand's high atmospheric salinity and widespread use of harsh chlorine/acidic tile cleaners make AISI 316 Marine Grade Stainless Steel mandatory for commercial guarantees. AISI 316 contains 2% to 3% Molybdenum, dramatically raising its Pitting Resistance Equivalent Number (PREN) and preventing stress corrosion cracking.
Available in Brushed Brass, Matte Black, Gunmetal Grey, Brushed Nickel, and Rose Gold. Vacuum PVD titanium plating provides ultra-hard surface scratch resistance (HV > 2000), enduring harsh daily scrubbing without fading or peeling.
Under-channel sound deadening rubber pads mitigate impact noise generated by high-velocity water droplets hitting the stainless steel trough, satisfying stringent acoustic reverberation standards in multi-story apartment complexes.
Removable 316 stainless steel hair catchers coupled with dry-seal silicone anti-odor check valves ensure smooth maintenance and prevent sewer gas backflow during seasonal droughts or low-usage cycles in holiday homes.
The New Zealand residential market is rapidly migrating away from 900x900mm acrylic shower trays in favor of fully tiled wet rooms. Tile-Insert linear drain channels (where a strip of floor tile is embedded into the drain cover) account for over 45% of total import demand in Auckland's architectural segment. Invisible slot drains and ultra-slim 20mm minimalist grates represent the fastest-growing niche in luxury builds across Queenstown and Wanaka.
Furthermore, high-density terrace housing developments driven by the National Medium Density Residential Standards (MDRS) require modular, repeatable linear drain units that allow fast-track installation for trade contractors. Our bulk pre-packaged project kits include waterproofing membranes, dry-fit traps, height adjustment blocks, and pre-sloped trough inserts designed to trim total trade installation time by up to 35% per bathroom unit.
We bridge the gap between high-volume precision manufacturing and strict localized compliance requirements for New Zealand plumbing distributors, hotel project managers, and sanitaryware wholesalers.
Custom channel lengths from 300mm up to 3000mm made-to-order within 7 working days. Laser branding of distributor logos, customized barcode labeling, and retail-ready packaging designed for NZ merchant display shelves.
Every linear drain unit undergoes 100% pneumatic pressure testing at 0.6 MPa to verify weld seam integrity before polishing. 24-hour salt-spray chamber testing ensures flawless corrosion resistance under ISO 9227 standards.
Streamlined ocean shipping routes directly servicing Auckland (Port of Auckland / Metroport), Tauranga, Lyttelton (Christchurch), and Wellington. Flexible Incoterms including FOB, CIF, and DDP with complete NZ Customs documentation clearance.
Clear, expert answers addressing compliance, manufacturing tolerances, shipping logistics, and technical specifications for buyers operating in New Zealand.
Yes. Our linear shower drains feature a continuous 30mm–50mm perimeter bonding flange specifically engineered to form a liquid-tight seal when integrated with liquid-applied waterproofing membranes under NZBC E3/AS1. We supply sand-etched metal flanges and pre-bonded fleece membranes for seamless liquid membrane adhesion.
We manufacture outlets specifically tailored for New Zealand waste pipes: DN50 (56mm OD) and DN75 (75mm OD). Outlets are available with central, offset, or dual outlet drops, featuring smooth male BSP threads or push-fit spigots compatible with Marley, Ipex, and standard NZ PVC sanitary pipework.
We strongly recommend specifying AISI 316 Marine Grade Stainless Steel for all New Zealand coastal installations (within 5km of the sea). AISI 316 contains Molybdenum which provides superior protection against chloride pitting caused by coastal salt air and aggressive chemical tile cleaners.
Absolutely. Our laser-cutting and automated bending lines allow us to produce custom drain lengths from 300mm up to 3000mm in single-piece units, or modular interconnected runs for public spa centers and commercial gym projects. Custom orders are dispatched within 10–14 days.
