## Long description

Undermount granite countertop washbasin deante CQS AU4S 600x400 mm is a compact rectangular sink designed for installation beneath a worktop. Manufactured from solid granite composite, the basin provides a hardwearing surface with a matte finish that resists everyday scratches and staining. Its 600 x 400 mm footprint fits typical undermount cutouts and is intended for residential bathrooms and light commercial washrooms where a discreet, integrated look and easy maintenance are required.
Advantages
The granite construction delivers thermal and impact resistance compared with standard ceramic bowls, while the undermount design creates a seamless transition between countertop and basin for easier surface cleaning. The compact rectangular shape maximizes usable counter space and simplifies installation in smaller vanities. The smooth internal geometry and durable surface finish reduce dirt accumulation and make routine cleaning with mild detergents straightforward.
Suitable for
 Residential bathroom vanity installations with undermount countertops

Key specifications
 Type: undermount granite countertop washbasin
 Shape: rectangular
 External dimensions: approximately 600 x 400 mm
 Material: granite composite (solid stone-based composite)
 Finish: matte, smooth interior surface
 Installation: designed for undermount fitting beneath a finished countertop
 Use: everyday residential and light commercial use
How to use
Prepare the countertop cutout to match the basin's dimensions and secure the sink to the underside of the worktop using suitable adhesive and mounting clips as recommended by the countertop manufacturer. Connect the waste and overflow (if applicable) to the existing plumbing according to local plumbing codes. After installation, seal the joint between countertop and sink with a compatible sanitary sealant to prevent moisture ingress. For daily use, operate like a standard bathroom washbasin.
Usage recommendations
Clean the granite surface with a soft cloth and a neutral pH cleaner; avoid abrasive pads, strong acids or alkalis to preserve the finish. Wipe away standing water and avoid dropping heavy objects into the basin to reduce the risk of chipping. For best results, follow countertop manufacturer's guidance for bonding and sealing to ensure a durable undermount installation.
