Description
The Clearwater Siena is a single-bowl kitchen sink made from Quarsil® granite composite, offering a 500mm bowl width and fine-radius corners that keep the look clean and contemporary. It suits kitchens where a flush, uncluttered worktop is the priority — the flat, raised-edge-free surface wipes down easily, and the choice of inset or undermount installation means it works with a wide variety of worktop materials and fitting styles.
Clearwater is a mid-range to premium sink and tap brand focused on combining practical performance with considered design. The Siena range is their granite composite line, available across nine Quarsil® colours — from neutral tones like Polar and Moonstone through to deeper shades including Onyx, Nero, Basalt, Concrete, and Mocha, plus the more distinctive Croma and Poppy. Quarsil® is Clearwater's own granite composite formulation, noted for its R12 slip-rated surface. The sink carries Clearwater's lifetime warranty.
The bowl measures 500mm wide by 400mm front to back, with a 200mm depth. A standard waste kit is included in the box. Cutout templates are available to assist fitting.
