Description
The Clearwater Lumen SB 340 is a compact single-bowl sink engineered for contemporary kitchens where clean lines and practical performance matter. Clearwater Sinks & Taps combines functionality with design versatility across their ranges, and the Lumen collection exemplifies their modern aesthetic with a focus on durability and choice.
The sink is manufactured from Quarex® granite composite — an advanced material comprising 80% quartz enriched with silver ions. These nano-particles form a protective coating on the surface, reducing bacterial and microbial growth by up to 98%. The result is a hygienic, dirt-repellent surface ideal for food preparation areas. Quarex® also delivers high resistance to scratches, impacts and heat, maintaining its appearance through daily use.
Installation is flexible: undermount for a seamless finish with solid surface worktops, or inset for compatibility with all worktop types including laminate. The bowl measures 340 × 400 × 200 mm (W × H × D), with an overall footprint of 390 × 450 mm, requiring a minimum 450 mm cabinet width. Available in a choice of six contemporary colours to coordinate with modern kitchen palettes.
The sink is supplied with a standard waste kit and backed by a lifetime warranty. It suits smaller kitchen layouts, utility rooms, or secondary preparation zones where space efficiency and geometric simplicity are priorities.
