In retrofit bathrooms with minimal slab depth, conventional floor waste bodies are too tall or rigid. Traditional grates often fail to line up cleanly with finished tile levels or pipe risers.
The Lowline Megaflex™ allows you to maintain a flush 100x100mm tile line with only minimal screed buildup. The flexible base tolerates ±10mm pipe deviation without stressing connections.
Use solvent cement rated for ABS when connecting Megaflex™ base. Confirm compatibility with waterproofing membrane penetration details.
Client expectations for visual finish, especially in boutique builds, require grates that match tapware and fittings while also being mechanically sound and easy to install across trades.
Select from five coordinated finishes, including living brass and matt black, to match broader design schemes. The brass grate and ABS base arrive pre-mated for easy installation and QA compliance.
Pre-plan grate placement during rough-in and screeding to ensure tile alignment and avoid costly repositioning later in the build.
Metric | Square Bermuda Lowline | Standard Alternative | Advantage |
---|---|---|---|
Outlet Compatibility | 50mm, 80mm, 100mm Highly Versatile | Typically 80mm only | Fewer SKUs to manage, broader on-site adaptability |
Installation Forgiveness | ±10mm Flex Tolerance Flexible | Fixed inlet only | Less rework, faster install |
Finish Range | 5 Designer Finishes Aesthetic Flexibility | 1–2 Basic Finishes | Suits designer and architectural projects |
Yes. The Megaflex™ ABS base is designed for screeded floors and slab installations. It allows minor adjustment to accommodate misalignment, making it ideal for retrofits or new builds with limited slab depth. Always ensure the waste is securely embedded before tiling.
The grate is available in Chrome, Matt Black, Brushed Gold, Brushed Nickel, and Polished Brass (Raw/Living Finish). These finishes are chosen to coordinate with modern tapware and bathroom accessories for a cohesive design outcome.
The Square Bermuda Lowline is offered with 50mm, 80mm, or 100mm outlets. For residential bathrooms, 50mm or 80mm is typically sufficient. For high-flow commercial or disabled-access wet areas, the 100mm outlet provides added capacity.
Yes. The Megaflex™ base is made from ABS plastic, which is solvent-weld compatible. Use an approved ABS solvent cement when bonding to pipework. Avoid twisting the base during installation to preserve internal seals.
The Polished Brass (Raw/Living Finish) will naturally oxidise and patina over time. To preserve its appearance, use a soft cloth and mild soap during cleaning. Avoid harsh abrasives or acidic cleaners. Protect the grate during tiling and grouting to maintain surface integrity.
Application / Use Case | Key Benefit | Primary Trades |
---|---|---|
Residential bathroom floor drainage | Low-profile design suits limited screed depth and matches tile lines perfectly | Plumbers, Builders |
Architecturally designed wet areas | Multiple premium finishes support seamless bathroom design aesthetics | Designers, Specifiers |
Multi-residential unit installations | Standard 100x100mm footprint and flexible Megaflex™ base reduce install time | Commercial Builders, Plumbers |
Aged care and accessible bathrooms | Wide outlet options (including 100mm) allow higher capacity for compliance | Hydraulic Consultants, Builders |
Designer renovations with living finishes | Raw polished brass patinas naturally for a high-end, evolving look | Interior Designers, Renovation Builders |
Ensure the floor substrate is structurally sound, clean, and dry. Confirm fall is formed correctly toward the waste location before applying membranes or adhesives.
Grind surface clean of laitance. Confirm no pooling occurs at the intended floor waste location.
Use compressed fibre cement sheeting and form screed to required fall. Waterproof as per AS 3740.
Fit the Megaflex™ base to the pipework using approved ABS solvent cement. Press base firmly into position while aligning vertical tolerance.
Apply ABS-grade solvent evenly to both the pipe and base socket. Insert and hold for 10 seconds to set.
Temporarily place base for height check, then remove and re-apply solvent cement for final fix.
Install membrane in compliance with AS 3740. Ensure full coverage around the waste and integrate membrane into the flange where applicable.
Brush membrane into the Megaflex™ base rim, allowing overlap onto the floor for continuity.
Embed fabric around waste with adhesive primer, ensuring tight bond with flange edge.
Once tiling is completed and grouted, insert the brass floor waste grate into the Megaflex™ base. Ensure alignment with tiles and test drainage flow.
Align the square grate to tile lines and press downward until seated flush.
Apply a small bead of neutral cure silicone around the inner lip if required for secure fit in high-traffic zones.
Wear cut-resistant gloves when handling brass components. Use eye protection if cutting screed or tile during fitting.
When using ABS solvent cement, ensure adequate ventilation. Use in open areas or provide exhaust extraction in confined spaces.
ABS cement is flammable — keep away from ignition sources. Store in a cool, dry place out of direct sunlight and away from flame or spark-producing tools.
Seek medical attention immediately in all cases of serious exposure.
Ensure all screed areas are fully cured and dimensionally stable. Clean surfaces to remove laitance, dust, and debris. Maintain a flat surface to allow the drain flange to sit flush.
For cementitious screeds in good condition, direct embedment is acceptable. Apply waterproofing as per system requirement before tile application.
Cut and clean pipework to ensure a square fit. Use a suitable plastic primer or cleaner to remove manufacturing oils and ensure solvent weld bonding is secure.
Use an approved PVC/ABS primer prior to solvent welding. Ensure full cure time before backfilling or applying mechanical loads.
Vinidex™ PVC PrimerWaterproof membranes must be fully cured and free from contaminants. Ensure the flange of the Bermuda Lowline Megaflex™ integrates securely into the membrane system with no pinholing or bridging.
For improved bonding with liquid membranes, prime brass flange with manufacturer-approved primers before membrane application.
Ardex P9 PrimerTimber must be structurally sound and reinforced with fibre-cement underlay. Fasten securely to prevent movement and seal joints with approved tapes or waterproofing compounds.
Use a moisture barrier primer on timber substrates before waterproofing membrane or flange installation.
