For indoor and outdoor drainage installations requiring a low-profile, high-capacity drainage channel, the Lauxes NeXT Generation 21 NXT21 Linear Drain Kit offers a highly customizable anodised aluminium system. This shallow 21mm deep drain integrates an anti-water tracking design to manage surface run-off efficiently, making it suitable for wet areas, patios, and driveways where height clearance is limited.
What it does
The NXT21 drainage system provides a modular, customizable channel drainage path. Water is captured through a sleek, roll-out top grate designed for fast removal during regular cleaning and maintenance. Engineered with an anti-water tracking design, the anodised aluminium tray channels water directly to the waste outlet without tracking along the underside of the grate. The system is UV stable to prevent degradation in outdoor service conditions and is backed by a lifetime rustproof warranty.
Numbers that matter
- 21mm depth: Extremely shallow profile for installation in screeds or suspended slabs where slab depth is restricted.
- 100mm width: Standard architectural width for seamless integration with floor tiles in indoor bathrooms or outdoor paved areas.
- Class B load rating: Rated for a maximum load of 10.2 tonnes, making it suitable for pedestrian areas and light vehicle traffic.
- DN90 40mm, 50mm, 72mm, and 80mm: Highly customizable waste outlet options to match common residential and commercial drainage pipe sizes.
Installation
The linear drain must be installed by a licensed plumber in accordance with AS/NZS 3500.2. All Lauxes grates and accessories are WaterMark Certified to WMTS-040.
For precise preparation, cut the bottom tray 3mm shorter than your final installation space to accommodate the end caps. The top grate should be cut 1mm shorter than the bottom tray to ensure a clean, drop-in fit. Use a compound mitre saw with a multi-material cutting blade (80 teeth or more) to ensure clean cuts, and drill the waste outlet with a Lauxes TCT hole saw. Secure the end caps and the pop waste to the tray using a trade-grade silicone bead.
Limitations
- Cement-based contact: Always use a template during installation to ensure the anodised aluminium grate does not come into contact with wet cement-based products, which can damage the anodised finish.
- Anodising wastage: For the 3.0m kit (total length 3.2m) and 5.6m kit (total length 5.8m), the total usable length is 3.0m and 5.6m respectively to allow for anodising process wastage.
- Maintenance restrictions: Do not use abrasive cloths, scouring pads, or acidic chemicals on the anodised grates during cleaning.
