Product Identity And Target Installations
What The TW 16503 W1690MM H370MM Lixil Represents
This configuration is optimized for projects where the 1690 millimeter width and 370 millimeter depth define the available cavity. It supports clean lines and minimal visual clutter while aligning with Lixil’s water management standards.
Ideal Rooms And Applications
Use in powder rooms, compact en suites, and niche areas where a conventional unit would protrude too far. The slim depth allows placement near mirrors or within half-wall columns without impeding movement.
Technical Specifications And Performance
Dimensional Precision And Layout Fit
Exact width, depth, and height figures ensure compatibility with standard timber studwork and prefabricated panels. Builders can verify cavity readiness before final fixings are installed.
Water Efficiency And Flow Characteristics
Designed to pair with Lixil controls that manage pressure and volume, delivering consistent performance while respecting local water regulations. Reduced turbulence supports quieter operation during peak demand.
Installation Guidelines And Best Practices
Mounting Requirements And Support Planning
Use manufacturer-recommended anchors and ensure vertical alignment across the full height. Reinforce the backline where wall conditions may compromise load transfer to the fixing system.
Maintenance Access And Long-Term Service
Plan service paths for valves and drains, keeping removable panels within reach. Regular checks of cartridge seals and exposed joints help prevent water ingress behind the finished facade.
Recommended Approach And Next Steps
- Verify the exact wall cavity dimensions against the W1690 × H370 mm layout before ordering.
- Confirm compatibility with existing supply lines and waste outlet heights.
- Select trim and fixtures that respect the 370 millimeter depth constraint.
- Schedule professional installation to align mounting points and seals precisely.
- Review local water efficiency standards to confirm flow and pressure compliance.
